Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle attitude adjustment device, and in particular, effectively utilizes a torsion bar stabilizer to reduce the difference in the left and right buffer clearance (gap between the buffer rubber and the chassis frame) of the vehicle. To provide an attitude adjustment device that can easily eliminate the left and right tilt of a vehicle without having to attach a vehicle.

In conventional vehicles, if there is an accumulation of weight errors in the parts that make up the vehicle or if a situation occurs where the left and right weight distribution is not appropriate, the vehicle may lean to the left or right. In vehicles with leaf spring suspension, this inclination was adjusted by interposing a spacer shim between the leaf spring and the axle, but this is preferable because the adjustment is in series and there is a difference in left and right buffer clearance. There wasn't. In addition, in vehicles with air splash suspension, this inclination was adjusted using rear axle leveling pulp ronds installed independently on the left and right sides, but this method could only be adjusted if the vehicle body's stiffness was small. However, there was a drawback that made it difficult.

The present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to interpose an elastic member, that is, a spring, between the axle and the chassis, and to provide a spring at one end of the pair or a torsion member. To adjust the suspension IT of a vehicle equipped with a torsion bar stabilizer in which a part of the bar is attached to an axle or a chassis, so that the left and right tilt of the vehicle can be adjusted very easily, and also so that a difference in buffer clearance between the left and right is caused. Vehicle posture that allows for 1. ! :v device.

Another example is when the vehicle user attaches optional parts to the vehicle and the left and right weight distribution of the vehicle changes, causing the vehicle to lean sideways.
．． The purpose is to be able to adjust the tilt of the vehicle by doing #l''.

In short, the present invention provides a suspension system for a vehicle that includes an elastic member interposed between an axle and a chassis, and a torsion bar stabilizer in which one end of a pair or a portion of a torsion bar is attached to the axle or the chassis. The device is characterized in that it is equipped with a left-right height adjustment mechanism that allows for a difference between the vertical and vertical mounting positions of the torsion bar stabilizer, the axle, and the chassis on the left and right sides of the torsion bar stabilizer. It is.

The present invention will be explained below based on the embodiments shown in the drawings. 1st
In the figure, a suspension system M of a vehicle 1 according to the present invention is shown.
2, a leaf spring 6, which is an example of an elastic member, is interposed between an axle 4 to which a wheel 3 is attached and a chassis 7 frame 5, which is an example of a chassis.See also FIGS. 2 to 6. The torsion bar stabilizer 8 is provided, and one of the pair of torsion bar stabilizers 48a+
8b is attached to the axle 4 via a connecting member 10 to a bolt 11, and a torsion bar 8118c is additionally attached to the chassis frame 5 by a pair of rods 12.12. Then, the mounting positions of the torsion bar stabilizer 8, axle 4, and Gyxi frame 5 are set to be different from each other on the left and right sides of the torsion bar stabilizer 1) S1! The height adjustment mechanism 15, which includes the j mechanism 15, has the first height adjustment mechanism 15 shown in FIGS.
In the embodiment, one of the rods 12 connecting the torsion bar msc and the chassis frame 5 is formed with a turnbuckle 16, for example, and the length of the rod is changed by rotating the central nut 17. The posture of the vehicle 1 tilted left and right is returned to a horizontal state by the reaction force acting on the chassis frame 5 from the stabilizer 8.

Same again <M4! In the embodiment shown in Q, the height 11'
In structure 15, the rod 12 may be configured with a turnbuckle 16, and a spacer 19 may be interposed between the nut 18 that tightens the upper end 12a of the rod 12 to the chassis frame 5 and the dispensing surface 5a of the chassis frame 5. Then, by changing the N-position of the spacer and thereby changing the length of the rod 12, the attitude of the vehicle 1 is also changed by the reaction force acting from the torsion bar stabilizer 8 on the chassis frame \5. 17 may be used to adjust.

Next, in the second height embodiment shown in FIG. 6, the height adjustment mechanism 15 includes a spacer 20 interposed between the connecting member 10 at one end 8a of the torsion bar stabilizer 8 and the axle 4, and By changing the thickness, the vertical position at which the torsion bar stabilizer 8 is attached to the axle 4 is changed, and the attitude of the vehicle 1 is similarly adjusted by the reaction force acting on the chassis frame 5 from the torsion bar stabilizer 8. .

The present invention is SN as described above, and its operation will be explained below. As shown in FIG.
(to the left in the figure), the shaft 7 frame 5 and torsion bar stabilizer 8 should move downward to the right (lower left in the figure) as shown in Figure 8 from the normal horizontal state shown in Figure 7. υ), and the length to of lot 12 at this time remains unchanged from the normal state. As shown in Figure 12, turnbuckle 16 of lot 12
When rod 7 is rotated in the direction that the rod becomes shorter, rod 1
The length of 2 is 4, which is shorter than 20 and becomes zl. However, one end 8a of the torsion bar stabilizer 8.

8b is connected to the axle 4 and remains horizontal with respect to the road surface 22, so the torsion bar stabilizer 8
In Figure 9, it is twisted as shown by the arrow AC.
As a result, the rod 12 is moved from the torsion bar portion 8c.
As shown by arrow B, a downward initial reaction force acts on
The rod 12 pulls the left end (right end in the figure) of the chassis frame 5 downward, the chassis frame returns to a horizontal state, and the vehicle 1 assumes a military horizontal state. In this case leaf spring 6
There is no difference in the buffer clearance between the chassis frame and the left and right sides of the vehicle 1.

Also, the length of the rod 12 is 1. In order to substantially reduce KIS, it is sufficient to make the spacer 19 thicker, and by doing so, a downward initial reaction force is also generated at the left end (right end in the figure) of the torsion bar portion 8c of the torsion bar stabilizer 8, and the force is pushed to the right. The tilted attitude of the vehicle 1 can be adjusted.

In addition, in the second embodiment shown in FIG. 6, if the vertical position of the weir with respect to the axle 4 of the connecting member 10 on the left side in the traveling direction of the vehicle 1 is changed, a downward initial reaction force that returns the vehicle 1 tilted to the right to the horizontal position is applied. occurs, so the size of the spacer 20 can be reduced, and the same result as on the male side can be obtained by doing so.Next, as shown in FIG.
If the wheel tilts to the left and the distance h between the chassis frame 5 and the top surface of the wheel 3 (indicating when the treadmill is normal) becomes shorter as shown by the solid line on the left side, do the exact opposite of the above. That's fine. That is, in the first embodiment, by rotating the nut of the turnbuckle 16 of the rod 12, the length of the rod is 1. The length t2 of the lot 12 may be substantially extended by making t2 longer, or by reducing the thickness of the spacer 19, thereby making the left end of the torsion bar portion 8c of the tone 1 number stabilizer An upward initial reaction force is generated at the right end in the figure, and the vehicle 1, which has tilted to the left, returns to a horizontal state.

Further, in the second embodiment, the thickness of the spacer 20 may be increased, which also allows the torsion bar portion 8 to
An upward initial reaction force is generated at the left end (right end in the figure) of c, and the vehicle 1 that has tilted to the left returns to a horizontal state.

In this case as well, there is no difference between the left and right buffer clearances, so no problem arises.

Since the present invention is configured and operates as described above, an elastic member, that is, a spring is interposed between the axle and the chassis, and one end of the pair is attached to the axle or a part of the torsion bar is attached to the axle or the chassis. In the suspension system of nine vehicles equipped with a torsion bar stabilizer, the left and right tilt of the vehicle can be adjusted very easily and without causing any difference in buffer clearance between the left and right sides. The effect of being able to provide a posture adjustment device is obtained. In addition, if the vehicle user installs optional parts on the vehicle, and the distribution of responsibility on the left and right sides of the vehicle changes, causing the vehicle to tilt sideways, the user can make a simple adjustment to improve the vehicle's position. It has the great advantage of being able to adjust the tilt. In particular, the present invention provides excellent effects in a suspension that combines an air spring and a torsion bar stabilizer.
