Description
【発明の詳細な説明】 本発明は車両用後輪懸架装置に関するものである。[Detailed description of the invention] The present invention relates to a rear wheel suspension system for a vehicle.

輪を回動可能に支持したトレーリングアーム式懸架装置
が一般に用いられている。As a rear wheel suspension system for an automobile, a trailing arm type suspension system is generally used, in which a wheel is rotatably supported at the rear end of a suspension arm that is attached to a member at the front end of the vehicle body so as to be rotatable in the vertical direction. ing.

たわみ量の設定が難しく、かえって車輪支持が不安定と
なる等の不具合を有している。The above-mentioned trailing arm type suspension system has a bushing made of an elastic material such as rubber interposed in the attachment part of the suspension arm to the vehicle body to absorb and reduce the transmission of vibrations from the wheel side to the vehicle body. Therefore, when a side force is applied to the wheel (outer wheel side) when turning, etc., the bushing bends and the wheel is angularly displaced in the toe-out direction, which worsens the steering stability.This problem is solved. Therefore, in a type of suspension arm that uses a two-pronged link, the link arm closer to the wheel is made of a leaf spring, and when a side force is applied to the wheel during turning, the link arm made of the leaf spring is A wheel that deflects inward to displace the wheel in the toe-in direction has been developed (see Japanese Patent Publication No. 52-34288), but if the suspension arm itself is made of a leaf spring as described above, the leaf spring will not respond to the side force. It is difficult to set the amount of deflection of the wheel, which results in problems such as unstable wheel support.

At the rear of the suspension arm 2, the rear part of the rigid arm 8 has an axle 6 projecting laterally at approximately the center thereof, so that the rear part of the suspension arm 2 can be rotated in the left and right directions by an approximately vertical shaft 5. installed,
The front part of the arm 8 is connected to a bolt 11. to a bracket 9 provided on the suspension arm 2 via an elastic body 10.10' such as rubber.
It is mounted so that it cannot easily be displaced in the vertical direction due to washers 12 and the like, but can be displaced around the vertical axis 5.

The arm 8 is rotatably mounted on a shaft 5 that is substantially perpendicular to the shaft 5, and the mounting portion by the shaft 5 is rigid against loads in a direction perpendicular to the axis of the shaft 5, that is, in a lateral direction. .1
Since it is attached to the bracket 9 of the suspension arm 2 with both sides of the arm 8 in the rotational direction around the axis 5 being clamped at 0', when a side force F is applied to the wheel γ such as when the vehicle turns, the arm 8 compresses and deforms the inner elastic body 10 to rotate inward (clockwise in FIG. 1) around the shaft 5, and the wheel 7 is angularly displaced in the toe-in direction, thereby improving steering stability. .

るものである。Compared to the elastic body 10.1σ, it is made thinner as shown in the figure so that it is considerably harder against loads in the left and right directions and less elastic deformation occurs, and side force F acts on the wheel T when turning. Then, the inner elastic body 10 of the front support part is greatly compressed and deformed with respect to the inner elastic body 13 of the rear support part of the arm 8, the arm 8 rotates inward about the rear support part, and the wheel γ moves in the toe-in direction. As described above, according to the present invention, the rear part of the arm, which receives the axle that supports the wheel in the middle part, is at the rear part of the suspension arm, so that it can be angularly displaced. The front part of the arm is attached to the suspension arm via an elastic body so that it cannot be displaced in the vertical direction, but can be displaced in the left and right direction within the range of deformation of the elastic body. With this structure, when a side force is applied to the wheel such as when the vehicle turns, the arm elastically deforms the elastic body of the front support part and rotates inward around the rear support part to move the wheel in the toe-in direction. The angular displacement is aimed at significantly improving steering stability, and the number of component parts is small. The amount of angular displacement in the toe-in direction against the side force is determined by the elastic deformation characteristics of the elastic body interposed in the front support part of the arm. This can be easily carried out by appropriately selecting the wheels, and stable wheel support can be ensured. Combined with the low cost, this can bring about great practical effects.
