した車両のリヤサスペシヨンに関する。[Detailed description of the invention] This invention relates to the rear suspension of an automobile.
More specifically, the suspension support member is attached to the vehicle body via a front cushion and a rear cushion that are spaced apart from each other, and the rotational axis of the wheel is aligned between the front cushion and the rear cushion in a plan view. This relates to a rear suspension of a vehicle in which a suspension arm that supports wheels is pivotally mounted so as to be located between the rear suspension arms.

るが、反面、前後に配置されるクツシヨンの剛性
によつて、乗心地や操縦安定性が影響を受ける。 A rear suspension is constructed by pivoting a suspension arm to a suspension support member, and attaching this suspension support member to the vehicle body via elastic cushions arranged at intervals in the front and rear. Compared to a type in which the arm is pivoted directly to the vehicle body, it has advantages such as excellent vibration isolation performance and ease of assembly on the production line. Comfort and handling stability are affected.

ーバステアとなる方向にサスペンシヨン支持部材
が変位するように、弾性変形し勝である。 That is, the cushions disposed at the front and rear preferably have low longitudinal stiffness in order to improve riding comfort, but they need to have high lateral stiffness in order to improve handling stability. However, since it is difficult to create a cushion with low longitudinal stiffness and as high lateral stiffness as possible, the stiffness is set at a compromise. With such a compromise in stiffness, lateral forces acting during a turn tend to cause the rear cushion to elastically deform in such a way that the suspension support member is displaced in a direction that oversteers the rear wheels.
本考案の目的は、後輪が横力を受けても、オー

2 to form a suspension support member, a semi-trailing member is attached to the suspension support member so that the axis of rotation of the rear wheel is located between the front cushion 24 and the rear cushion 26 in plan view. The arm 10 is pivotally connected, and the suspension support member is attached to the vehicle body via cushions 24 and 26. Thereafter, the restraining means 30 are attached to the vehicle body and to the rear of the suspension support member.

後輪はアンダステアにもたらされる。 While the vehicle is running, the suspension support member is displaced in the longitudinal and vertical directions due to the elastic deformation of the cushion. When the vehicle turns, the suspension support member tends to displace laterally due to the lateral force applied to the rear wheels, but since the restraining means 30 is provided, the rear part of the suspension support member is not displaced laterally. is regulated. In this way, the stiffness of the cushion 26 in relation to the rear member 22 is
It can be set to be sufficiently soft. On the other hand, the restraining means 30 restricts the lateral displacement of the rear part of the suspension support member, but has little effect on the front part. Therefore, due to the lateral force acting on the rear wheel, the cushion 24 associated with the front member 12 is deformed as in the conventional case.
The rear wheels are brought into understeer.

き、操縦安定性を向上できる。 According to the present invention, since the lateral displacement of the rear part of the suspension support member is regulated by the restraint means, it is possible to set the cushion placed on the rear side to be sufficiently soft, resulting in a comfortable ride. can be improved. In addition, although the restraint means restricts the lateral displacement of the rear part of the suspension support member, it has almost no effect on the displacement of the front part, so when turning, the suspension disposed on the front side deforms. By displacing the front portion of the suspension support member, understeer can be added to the rear wheels, and steering stability can be improved.
