Three-wheel solar car suspension with automatic roll function

technical field

The invention relates to a vehicle frame of a three-wheel solar vehicle with an automatic roll function, and belongs to the technical field of vehicles.

Background technique

The power of a practical solar car is very small, generally less than 1000W due to the limitation of the area of the solar panel. Due to the limitation of power, the body weight of the solar car is required to be as light as possible, but the lighter body is easy to roll over when turning, and the comfort is poor, and the components are easy to be damaged. Therefore, the stability of the light solar car body can be increased when turning, so that the body can automatically roll when turning, so as to adjust the center of gravity to increase the stability of the car body, and at the same time increase the comfort of passengers and drivers. This is the light solar car Challenges faced in bringing to market.

Contents of the invention

The technical problem to be solved by the present invention is to provide a three-wheel solar car suspension with automatic roll function, which can ensure that the three-wheel solar car can automatically tilt with the size of the centrifugal force when the vehicle body is light. Increase the stability of the car body when cornering and the comfort of passengers and drivers.

The solution adopted to solve the technical problem of the present invention is: in the seat box of the three-wheel solar car, a support frame is fixed, the lower end of the support frame is welded together with the main beam of the vehicle, and a vertical vibration-damping support is fixed in the middle of the rear wheel axle. column, and a swing bearing is installed at the top of the vibration-damping support column, and the middle part of the upper end of the support frame is hung on the swing bearing.

The shape of the support frame in the above-mentioned seat box can be a symmetrical A-frame, and the intersection point of the upper rods is fixedly connected to the rotating shaft, and is suspended on the swing bearing through the rotating shaft; the vibration-damping support column is a casing structure, and the vibration-damping spring is installed Inserted into the casing, the vibration-damping support column can damp vibration in the vertical direction in the casing. In order to prevent the vehicle body from swinging randomly, a damping sheet is installed between the support frame and the shock-absorbing support column.

The beneficial effects of the invention are: no power required, low noise, no pollution, compact structure, small size, light weight, convenient and flexible use, extremely low cost, and easy maintenance; it is suitable for use on light-duty three-wheeled solar vehicles; it can realize Automatically tilt the body according to the size of the centrifugal force, so as to achieve the purpose of adjusting the center of gravity to increase the stability of the body and the comfort of the ride.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawings 1 to 3 and embodiments.

The suspension of the three-wheeled solar car is mainly composed of an A-type support frame 3, a roll swing bearing 4, a vibration-damping support column 5, and a damping sheet 6. The support frame 3 is fixed in the seat box 2, and its lower end is welded together with the vehicle main beam 10. The weight of the passenger, the driver and the vehicle floor all presses on the vehicle main beam 10. The top of the A-shaped support frame 3 is equipped with a rotating shaft and is suspended It is hung on the fixed swing bearing 4 at the upper end of the damping support column 5, so that the A-type support frame 3 can freely swing on the vibration damping support column 5, and can perform damping motion up and down simultaneously. When the solar car is stationary, when a person gets on the car from one side, although a lateral force is applied, the front wheels are in contact with the ground, and there is static friction, which constrains the main beam connected to the front wheels, and the body does not swing. roll. During the movement, the front wheel and the ground are in rolling friction, and its friction force is much smaller than the static friction force. The constraint between the front wheel and the ground is reduced, and the faster the relative movement, the greater the influence of the lateral force on the swing of the main beam. When going straight, there is no centrifugal force. At this time, the A-type support frame 3 does not swing, and the vibration exists in the direction perpendicular to the road surface. The vibration-damping support column 5 moves up and down to reduce vibration; when turning, due to the effect of centrifugal force, the car body The center of gravity of the car body begins to deviate, and the center of gravity of the front part of the car body is shifted by the roll of the front wheels, while the center of gravity of the rear part is on the main beam 10, and the center of the swing bearing 4 begins to swing outwards, so that the entire body floor begins to deflect, The outward shift of the center of gravity ensures the stability of driving, and the size of the deflection angle depends on the size of the centrifugal force, which also realizes the function of automatic body roll when turning. In order to prevent the vehicle body from swinging randomly, a damping sheet 6 is sandwiched between the shock-absorbing support column 5 and the A-shaped support frame 3 .
