Abstract

PURPOSE:To automatically adjust the inclination of a seat by using a motor and an inclination detecting sensor and rotating the motor in the normal and reverse directions according to the inclination measured value. CONSTITUTION:When a motor 44 is rotated in the normal and reverse directions, the decelerating rotating force is transmitted to a rotating cylinder 51 to turn a seat 32 forward and backward. An inclination sensor 43 is fixed to the side of a rotating plate 42, thereby obtaining the angle between the direction of gravity and the direction of rotating plate 42. That is, the inclination sensor 43 detects the forward and backward inclination of the seat 32. When the inclination sensor 43 detects the forward and backward inclination of the seat, a motor 44 is driven to turn the seat 32 in the reverse direction, so that the seat 32 is always kept horizontally.

Description

[Detailed Description of the Invention] (2) Summary A new passenger trolley is connected between the power car and the trolley of a single-gauge transport vehicle.

Passenger trolleys are used to transport people. It has a seat on which a person can sit.

The tilt of the seat in the longitudinal direction is detected by a tilt sensor.

To rotate the seat back and forth, a motor, worm,
Equipped with a rotating mechanism such as a gear.

The tilt sensor's tilt readings cause the motor to rotate forwards and backwards, automatically adjusting the seat's tilt. This allows humans to sit horizontally at all times.

(b) Technical field Single-track transport vehicles are installed in hilly areas such as tangerine orchards.

It is used for transporting agricultural products, fertilizers, etc.

There is only one rail. Easy to install.

It is equipped with a drive mechanism in which a rack and a pinion are engaged. This makes it easy to go up and down steep slopes.

A conventional single-rail transport vehicle is made up of a power vehicle and a truck connected together.

A power vehicle includes a power transmission system such as an engine, a reduction gear, and a pinion, and a braking system.

The braking system includes a normal stop brake, a constant speed brake,
It often includes an emergency stop brake.

A trolley is used to carry cargo. Although the bogie has the ability to run on rails, it has no power or braking mechanism.

Single-track transport vehicles are not allowed to be ridden by humans.

This is because it is dangerous. Naturally, there is no space for humans to ride.

Since there are no humans on board, the single-track transport vehicle runs unmanned from the beginning to the end of the laid rails.

It also has all the mechanisms for unmanned driving.

At the starting point, one worker loads or unloads the load, unlocks the stop brake, and pulls hard on the engine starting wire to start the engine and start the motor vehicle.

The single-track transport vehicle travels unmanned on the rails until it reaches its final destination.

At the end point, there is a brake stick on the ground near the rail. When the motor vehicle reaches this point, the brake rod hanging from the motor vehicle collides with the brake stopper rod. The brake lever rotates and the brakes are applied. The transport vehicle stops.

The other worker at the end of the line unloads or loads the load, switches gears in the opposite direction, and starts the engine again.

In this way, single-gauge transport vehicles were, in principle, to run unmanned.

However, with this transportation method, at least one worker must be on standby at each end of the rail. However, the number of people engaged in agricultural work is decreasing.

It is becoming increasingly difficult for two people to be on either end of the rails of a single-gauge vehicle at any given time.

Therefore, the following method is used as an expedient.

One person does all the work. Start the single-track transport vehicle at the starting point and walk with the transport vehicle to the final point. Loading and unloading work is done here. In this way, one person moves along with a single-gauge truck.

The law stipulates that no humans are allowed to ride in single-gauge transport vehicles.

However, single-track transport vehicles are sometimes faster than walking speed, so it is not always easy to follow them on foot.

Moreover, there are many slopes, so it can be difficult to walk.

Therefore, in reality, workers often ride on single-track transport vehicles instead of walking. It will be easier if you do this.

However, single-gauge transport vehicles were not originally designed to be ridden by humans. It is often dangerous. You may fall and get injured. It is not safe because it takes up a small space on the cargo bed.

The Ministry of Agriculture, Forestry and Fisheries also appears to be willing to permit passenger mole rail.

In fact, there are many people who ride single-gauge transport vehicles, and if they do not ride them, they cannot perform agricultural work efficiently. It is unrealistic to ban riding. The intent of the law is to prohibit riding because it is dangerous. However, on the other hand, it would be better to create something with a high degree of technical perfection that is safe to ride.

Since people still ride them today, they should make something that they can ride with peace of mind.

For this reason, the Ministry of Agriculture, Forestry and Fisheries also seems to be planning to ease restrictions.

(2) Prior art technology for passenger trolleys Since it is prohibited for people to ride on single-gauge transport vehicles, there are no single-gauge passenger transport vehicles that are widely used in public. Lack of technical knowledge.

JP-A-52-22212 (February 19, 1977) and JP-A-52-22213 (February 19, 1977) disclose a passenger single-rail transport vehicle. This has a twist on the brakes.

The seats are fixed. There are no improvements to the seats.

2) Technical issues of passenger single-rail transport vehicles Passenger single-track transport vehicles are required to:

(1) The vehicle can be stopped and started by the passenger's operation.

(2) The passenger trolley on which the passenger rides must have an independent brake separate from the motor vehicle's braking system.

(3) Passengers should not be injured by sudden rake.

(4) The rider should be able to maintain a comfortable posture when climbing up and down slopes, mountains, and valleys.

etc. Of these, (1) and (2) can be solved by providing a new brake to the passenger trolley.

(3) Ha';' Overcome and kill by selecting and adjusting the rake.

Issue (4) is likely to be overlooked, but it is an important issue.

A single-track transport vehicle runs on rails with many ups and downs, like a roller coaster. However, unlike roller coasters, the length of the train is not long.

If a passenger trolley is added, it will be short in the longitudinal direction and tall in the vertical direction. It becomes vertically long and unstable.

If the relationship between the seats and wheels of a passenger trolley is fixed, the following problems will occur.

When going downhill, gravity tends to cause you to slide forward from your seat.

When going uphill, the center of gravity will shift to the rear, making you feel like turning backwards.

If the seat is fixed, there is a risk of falling forward or backward.

In fact, the site where the single-gauge vehicle is laid may include a slope of 45°.

If the slope is around ±100, a fixed seat may be used. However, if it exceeds 3o0, it is dangerous for fixed seats.

It is better not only from a physical safety point of view, but also psychologically that the seat be horizontal.

(3) Prior Art of Movable Seats The present inventor noticed the importance of passenger single-rail transport vehicles from an early stage.

He has also invented several passenger trolleys that can adjust the seat angle depending on the inclination angle.

1) Japanese Patent Publication No. 60-60057 (S 60.4.6)
2) Japanese Patent Publication No. 60-60058 (S 60.4.6)
3) Japanese Patent Publication No. 60-76459 (S 60.4.30
)4) JP-A-61-81269 (S 61.4.'2
4) 1) has a swing-type swing mechanism. The seats are suspended from pillars erected on both sides, so that the seats face straight down due to their own weight. Of course, there is also a locking mechanism. Adjust the tilt, then lock.

(2) is effectively the same as the swing type. Fix the arc-shaped rail to the trolley side. There are rollers under the seat. This roller rolls on the rail.

Similar to swinging on a swing, the seat rolls back and forth on an arc-shaped rail and automatically stops facing straight down.

It also has a locking mechanism.

In both (1) and (2), when the inclination angle changes, the rider removes the locking mechanism, adjusts the inclination again, and locks.

You often have to adjust the tilt angle yourself.

(3) also has a swing-type tilt angle adjustment mechanism.

In (4), one end of the seat is pivoted, and the height of the other end can be changed.

At the other end is a pillar with several bolt holes. Secure the ends of the seat with bolts inserted through either bolt hole.

All of these seats allow you to change the direction of the seat back and forth. Moreover, it has the advantage that no particular energy is required to change the inclination of the seat.

However, each has its drawbacks.

(4) requires bolts to be attached and removed, so the angle of inclination can only be changed when the vehicle is stopped.

This can only be used when traveling on rails with a constant slope.

In (2), even if the center of gravity is below the center of the arc, the resistance of the roller is large and it may not move smoothly.

(1) and (3) are easy to swing because they are suspended by swings, but the swings do not stop immediately at the optimal point.
The seat is not necessarily level when the lock is engaged. The vehicle uses the rider's senses to detect the horizontal position and lock the vehicle, but this is not reliable and the vehicle may lock at an angle.

However, the biggest difficulty with (1) and (3) is that the device becomes large-scale because the seat is suspended by a swing. This increases manufacturing costs. It also makes the transport vehicle heavier. This reduces the amount of luggage you can carry. Additionally, the left and right sides of the passenger are blocked by pillars.

This makes it inconvenient and cramped to get on and off the train.

A problem common to (1) to (4) is that in all of them, the tilt adjustment is not automatic and must be performed by the passenger at any time.

This is not only a hassle, but also a safety issue.

Qω Purpose It is an object of the present invention to provide a passenger carriage of a single-track transport vehicle with a mechanism for automatically leveling the seat.

(1) Configuration The passenger trolley of the single-rail transport vehicle of the present invention uses a motor and an inclination sensor to automatically keep the seat level.

For this reason, the seat can be rotated forward and backward.
Supported by a fulcrum shaft. Then, the seat can be rotated by an arbitrary angle around the fulcrum shaft using the motor.

A tilt sensor attached to the seat side detects the difference between the seat surface direction and the horizontal direction, and the motor is rotated so that this difference becomes O, automatically adjusting the seat angle.

The contents of the present invention can be summarized as follows.

More specifically, the configurations of the present invention are enumerated as follows.

The passenger bogie of the single-rail transport vehicle of the present invention comprises: (1) upper wheels that sandwich the rails from above and below;
2) a vehicle frame that rotatably supports the upper and upper wheels; (3) a support box supported by the vehicle frame; and (4) a support box pivotally connected to the support box by a fulcrum shaft so as to be rotatable back and forth. (5) An inclination sensor that detects the inclination of the seat, (6) A battery attached to the vehicle frame, (7) A motor attached to the support box that can rotate in forward and reverse directions, and (8) The rotational force of the motor. (9) A binion that is fixed to the axle of the vehicle frame and meshes with the rack; (10) Coaxial with the binion or via a reduction or speed increase mechanism. It consists of an emergency brake that is installed on the vehicle, and a handbrake that allows the passenger to operate the emergency brake (formerly).

Among these elements, (1) is the driving function. This is because you are running on rails, so of course you have to be prepared.

(9) to (II) relate to the braking mechanism. This is also used in the passenger trolley mentioned above.

The novel features are elements (2) to (8) for automatically adjusting the inclination angle of the seat.

(R) Embodiment FIG. 1 is a side view of a single-rail transport vehicle including a single-rail passenger trolley according to an embodiment of the present invention.

FIG. 2 is a side view of only the power vehicle and passenger truck, FIG. 3 is a plan view, and FIG. 4 is a rear view.

The single-rail transport vehicle includes a power vehicle 1, a passenger trolley 2, and a loading trolley 3.
It is made by connecting.

The single rail that supports these consists of a rail 4 with a rectangular cross section, a rack 5 welded to the side surface of the rail 4, and a support 6 that supports the rail 4 on the ground.

The power vehicle 1 is for towing the entire transport vehicle.

The power vehicle 1 has a frame 7 made of aluminum alloy, cast iron, or the like.

Upper wheels 8 and 9 are attached to the frame 7 via axles.

The motor vehicle 1 has a power source such as a fuel tank 10 and an engine 11. The rotational force of the engine 11 is transmitted to the drive pinion 18 through a gear reduction system located inside the frame 7.

Operations such as forward/backward movement and gear changes are performed using the mission switch (-13
It is done by

By operating the stop-start lever 14, a stop brake (not shown) is activated or released.

A constant speed brake 15 for a power vehicle is provided on the side of the frame to prevent the speed from exceeding a certain level.

In addition to this, there is also an emergency stop brake.

Such motor vehicles have been manufactured by the applicant for some time.

The cart 3 is used to carry luggage.

The loading truck 3 has a wide loading platform 20 supported by two vehicle racks 21, each of which has one BL. The vehicle frame 21 has an upper wheel 22 and a lower axle 23. A luggage fence 24 is erected in front and behind the loading platform. Fences may also be erected on the sides.

The cart 3 has also been manufactured by the applicant for some time.

The passenger trolley 2 will be explained.

The passenger trolley 2 is supported by a carriage 25 with respect to the rails 4.

The vehicle frame 25 is made of aluminum, aluminum alloy, cast iron, or the like.

The vehicle frame 25 is rotatably provided with an upper wheel 26 and a lower axle 27 that sandwich the rail 4 from above and below.

One of the lower axles is provided with an emergency brake 28 and a pinion 29 connected to it and meshing with the rack 5.

When the emergency brake 28 is actuated, the pinion 29 connected thereto stops. Since the pinion 29 is engaged with the rack 5, the passenger trolley 2 stops.

This is activated by the passenger pulling up the handbrake lever 33 when he/she wishes to stop the vehicle in an emergency.

Further, a constant speed brake 31 for a bogie is provided diagonally in front of the vehicle frame 25.
will be provided. This is to prevent the speed from increasing too much when disembarking, and to keep the train running at a constant speed. Although it is installed on power vehicles, it is also installed on passenger trolleys.

A basic frame 35 is attached to the vehicle frame 25 via a universal joint 60 and a plate 64.

The universal joint 60 allows rotation in the horizontal direction and rotation in the front-back direction.

For this reason, a vertical shaft 62 is provided upward from the center of the vehicle frame 25.

The vertical shaft 62 can be rotated horizontally.

Above the vertical axis 62 is a horizontal axis 63.

The receiver has brackets 65 on the left and right lower surfaces of a plate 64, and both ends of a horizontal shaft 63 are inserted into holes in the brackets. Therefore, the support plate 64 can rotate around the horizontal axis 63 in the front and rear directions.

The universal joint 60 thus allows horizontal rotation and longitudinal rotation, but prohibits rotation in the left-right direction. This is natural since the seat must be supported.

The basic frame 35 is bent downward at the front, becomes horizontal, and is connected to the power vehicle 1 by a universal joint 61.

A wide footrest 30 is fixed to the front horizontal part.

The basic frame 35 is a rigid body made by bending iron or the like.

This is supported by a universal joint 61 at the front and a universal joint 60 at the rear.

The front universal joint 61 also has a vertical shaft 66 and a horizontal shaft 67.

Allows horizontal and vertical rotation.

The rails may appear pale in the vertical direction.

This is because the basic frame 35 rotates around the horizontal axis 63.67, so it can follow the rail blue curve.

Sometimes the rails curve horizontally.

Since the basic frame 35 rotates around the vertical axes 62 and 66, it can follow the forward curve of the rail.

In this way, the center of the vehicle frame 25 and the universal joint 61 of the power vehicle 1
The basic framework 35 is stably supported on the line connecting these.

A handbrake lever 33 is provided on the basic frame 35 so as to be movable up and down. This and the emergency brake are connected by a handbrake wire cable 34.

A U-shaped support box 40 with an upward opening is fixedly installed on the basic frame 35.

A fulcrum shaft 41 is supported on both sides above the support box 40.

The seat 32 has a rotating plate 42 vertically attached to its central lower surface.

A rotating cylinder 51 is fixed in front of the rotating plate 42.

The aforementioned fulcrum shaft 41 is inserted into the rotating tube 51 .

The seat 32 can rotate back and forth about the fulcrum shaft 41. This means that when the rail tilts back and forth,
This is to keep the seat 32 substantially horizontal.

DC motor 4 to provide power to rotate the seat
4 is attached to the side of the support box 40.

A battery 45 is mounted on the plate 64 to drive the DC motor 44 .

FIG. 5 shows the AA cross section and the BB cross section in FIG. 2.

The DC motor 44 is decelerated by a worm gear 46 .

Several gear trains are rotatably attached to the sides of the support box 40.

A first small gear 47 is fixed to the worm gear shaft.

The first small gear 47 meshes with a first large gear 48 located diagonally rearward.

The first large gear 48 is integrated with a second small gear 49 on the side, and is rotatably supported by an intermediate shaft 52.

The second small gear 49 meshes with the second large gear 50.

The second large gear 50 is welded to the rotary cylinder 51. Rotating tube 51
is fixed to the rotating plate 42 and the seat 32.

Therefore, when the motor 44 rotates in the forward and reverse directions, the deceleration rotational force is transmitted to the rotating tube 51, causing the seat 32 to rotate back and forth.

A tilt sensor 43 is attached to the side of the rotating plate 42. This allows the angle between the direction of gravity and the direction of the rotating plate 42 to be determined.

In other words, the inclination sensor 43 can detect the inclination of the seat in the longitudinal direction.

When the tilt sensor 43 detects the tilt of the seat in the longitudinal direction, it drives the motor to rotate the seat in the opposite direction. This way, your seat will always remain level.

There are side rails 39 on both sides of the seat 32.

A controller 36 is attached to one side of the hand t11) 39.

In order to reduce the rotational force of the motor 44, a reduction gear train consisting of a worm gear and a spur gear is used in this example.

However, the configuration of the reduction gear is arbitrary. It is also possible to use two stages of worm gears. You can also increase the speed reduction of the spur gear by one or two steps.

Alternatively, a planetary gear reducer can also be used.

The side rails 39 serve as a handhold when sitting on the seat 32 and when exiting the vehicle, and have the effect of keeping the passenger's posture stable during travel.

A front handrail 38 is vertically erected from the front of the basic frame 35.

The passenger sits on the seat 32, places both feet on the footrest 30,
Hold the front handrail 38 with both hands. This is a safe position.

Although the braking mechanism is not the main focus of the present invention, since braking is important for passenger vehicles, this will be explained.

Constant speed brakes 15.31 are provided both on motor vehicles and on passenger vehicles.

In order to stop at the starting and ending points, an automatic operating rod (not shown) is suspended from the lower right side of the motor vehicle. This is connected to a stop brake (not visible in the diagram).

When the automatic operation stopper hits the stopper rods set at the start and end points,
The automatic operation lever rotates and automatically applies the brakes.

A stop/start lever 14 is attached to the same member as the automatic operation lever. This can be rotated back and forth as shown in FIG.

The forward leaning position is the starting position. The position when standing back is the position when stopped.

The vehicle is traveling with the stop/start lever 13 tilted forward. When you pull this back, the brakes are applied.

However, it is not easy to operate for the passenger of the passenger trolley to reach out and pull up the stop/start lever 13.

Therefore, the brake support shaft 53 to which the stop/start lever 13 is attached
Attach the foot brake lever 37 to.

When the foot brake lever 37 is stepped on with the foot, the brakes of the power vehicle are applied.

When the passenger wants to stop the vehicle urgently, he or she depresses the foot brake lever 37 with his foot and pulls up the 71st brake lever 33 with his hand.

The foot brake operates the brakes on the motor vehicle, and the hand brake operates the emergency brake on the passenger trolley.

The foot brake lever 37 is connected by the accelerator wire 55.
When the pedal is depressed, the engine will stop.

The above-mentioned Japanese Patent Application Laid-Open No. 60-60057.60-60058.
60-76459, 61-81269, etc., when the handbrake was pulled, the brake of the passenger trolley was activated and the engine of the motor vehicle connected by wire was stopped.

In the case of the present invention, in order to make such a braking mechanism even more reliable, the brakes of both the power vehicle and the passenger truck are operated simultaneously.

The foot pedestal 30 has a horizontal plate, a front inclined plate 68 in front, and a rear inclined plate 69 in the rear.

The angle of inclination of the forward tilting plate 68 is 50° in this example.

The angle of inclination of the rear tilting plate 69 is 60° in this example.

The most distinctive feature of the present invention is that the seat can be kept horizontal at all times by automatically changing the angle of the seat.

Therefore, this part will be further explained.

The fulcrum shaft 41 and the rotating cylinder 51 serve as a center Q of rotation of the seat.

The center of gravity G when a passenger sits in a seat differs from person to person,
It also depends on how you sit.

However, the average center of gravity position G can be determined.

It is mechanically convenient to set the center of rotation Q so that it lies midway along a vertical line drawn from the center of gravity G.

However, experiments have shown that doing so does not make sitting comfortable.

This causes the feet to protrude in front of the foot rests 30 when the user leans forward. When I lean backwards, the soles of my feet don't touch the foot rests 30, which makes me feel uneasy.

Even if the seat rotates back and forth, it is better not to change the position of your feet too much. For this reason, the center of rotation Q is changed from the center of gravity G
be positioned in front of the vertical line that passes through it.

The center of rotation q is about 160 degrees ahead of the vertical line passing through G (when the rail is horizontal).

The tilt sensor 43 generates an output voltage (2) according to the angle θ formed by the direction of the sensor with respect to the direction of gravity.

A commercially available product can be used for this.

For example, Accustar Cli manufactured by 5PERRY
nomC11no trademark name).

FIG. 7 shows the relationship between the tilt angle θ and the output voltage V.

In this way, the linearity of the output voltage is extremely good.

The electric circuit will be explained with reference to FIG.

The tilt sensor 43 is attached to the seat and generates an output voltage V according to the tilt angle θ of the seat from the horizontal.

This power, lid (r): 27/Z L/-tar GO
The signals are input to the non-inverting input and inverting input of MPI and GOMP2, respectively.

The upper reference voltage U is provided by a variable resistor 70 connected between the power supply and ground.

The lower reference voltage is provided by a variable resistor 71.

U is connected to the inverting input of GOMP 1, and D is connected to the non-inverting input of (:OMP 2.

The terminals b1 c of the DC morph 44 are connected to the terminal a of the battery 45 and the ground I via four switches.

Switches SWI and S are connected between terminals S and C and terminals S and S.
W3 is connected.

A switch SW4 is connected between terminals C and ground G.
sw2 is connected.

SWI and SW2 open and close at the same time by the output U of COMP l.

The output d of GOMP 2 causes SW3 and SW4 to open and close at the same time.

The battery 45 is a rechargeable battery, and the battery 45 is a rechargeable battery.
1, it is constantly charged.

Current is drawn from a power generation coil 74 provided close to a rotating magnet linked to the engine, through a lighting line 72, to a diode rectifier 73.

Since the electromotive force of the generator coil 74 is alternating current, it is bridge rectified to charge the battery 45.

The effect of Fig. 8 will be described.

When the seat is approximately horizontal, the output V of the tilt sensor is higher than the lower reference voltage and lower than the upper reference voltage U.

D≦V≦υ (1) At this time, the outputs u and d of COMP l and GOMP 2 are both at L level. In this case, the motor will not move.

When the rail starts descending, the seat tilts forward (θ〉0)
Therefore, the sensor output V increases.

When the upper reference voltage U is exceeded (v>U), the output U of COMPl becomes H level. Therefore, SWI and sw2 are closed.

From battery 45, 4% bs cs j! As such, a current flows. Current will flow in the motor 44 in the forward direction.

The worm gear 46 and gears 47 to 50 rotate at a reduced speed. The rotating tube 51, the rotating plate 42, and the seat 32 tilt rearward.

As the vehicle tilts backward, the sensor output V decreases.

Eventually, it will fall into the range of (1). GOMP 1 output U is L
become the level. SWI and SW2 open. Motor 4 stops.

This will return it to almost horizontal.

When the rail goes up, the seat tilts backwards (θ〈0)
.

Sensor output V decreases. V (When it comes to D, GOMP
The output d of 2 becomes H level. SW3 and SW4 close. Motor 44 rotates in the opposite direction.

The seat tilts forward. Eventually, the sensor output V returns to the range (1). The motor will stop. The seat is almost horizontal.

In this way, the inclination of the seat is automatically adjusted whether the rail is going up or down.

If the distance between U and D is small, the motor will rotate frequently to maintain the horizontal position.

If the distance between U and D is large, the motor will rotate less frequently, but the seat will not necessarily be level.

Therefore, for both U and D, the seat is 2.5 degrees from the horizontal.
The value is chosen to be equal to the value of V when the angle is shifted by 3.0°.

This means that the maximum inclination of the seat is 2.5° to 3.0°.

The maximum inclination of the rails of single-track vehicles is 45°. Therefore, it is preferable to rotate the seat within a ±45° rotation range.

However, when tilting backwards, it is approximately 15 degrees, and when tilting forwards, it is approximately 10 degrees.
I know that to a certain degree, I don't feel anxious.

Therefore, the seat angle adjustment range is at least 30
°, later 35° is necessary.

(2) Effects (1) In the past, people were often forced to ride on single-track transport vehicles that had little room for people to ride.

This was dangerous. According to the present invention, it becomes possible to connect a passenger trolley to a single-gauge transport vehicle.Agricultural work can be carried out safely and efficiently.

There are seats so you won't feel tired.

(2) Even if the rail is tilted, the seat is automatically maintained horizontally.

The human upper body is always maintained in a safe state.

Since it is not manually operated by a human, it does not require any skill from the rider. Frees you from complicated adjustment work.

In other words, even unskilled people can ride it.

(3) Since the tilt sensor detects the discrepancy between the direction of gravity and the direction of the seat, horizontal control can be achieved with high precision. In terms of motor load. Although it may be set to about ±25° to +3.0°, it is also possible to perform high precision control to about ±1.0°.

In this respect, it is superior to the swing type.

(4) Since the passenger trolley is also equipped with a brake, the passenger can easily stop the vehicle.
