Abstract

In a multi-link rear suspension ( A ) in which a wheel support ( 11 ) is connected to a vehicle body through five links ( 6-10 ) and vehicle body side ends of the links are provided with rubber bushes ( 26 ), respectively, the lower end of a damping device ( 14 ) formed by coaxially arranging a coil spring ( 12 ) and a damper ( 13 ) is pivoted to a portion of the wheel support ( 11 ) located toward the inside of the vehicle body so that the vertical reaction force of the damping device ( 14 ) produces a moment Mn toward negative camber on a rear wheel (2) . The moment Mn is set to be always larger than a moment Mp toward positive camber produced by a side force on the outside rear wheel. The damping device ( 14 ) is disposed with respect to a suppositive king pin axle K so that the vertical reaction force thereof produces a moment toward toe-in on the rear wheel ( 2 ). In this manner, the multi-link suspension provides a sharp driving feeling applicable even for a sports car while maintaining a good ride through the involvement of the rubber bushes (26).

Description

technical field

[0001] The invention relates to a rear wheel suspension device of an automobile, in particular to a multi-link suspension composed of five I-shaped connecting rods. Background technique

[0002] A conventional multi-link suspension is composed of five I-shaped links, and each link has an elastic bushing at least at its end on the vehicle body side (for example, refer to Japanese Patent Application Laid-Open No. 2-38106). This multi-link suspension composed of 5 I-shaped links can arrange each I-shaped link to correspond to 5 degrees of freedom of motion except the up and down stroke of the rear wheel, so that the rear wheel The movement of the wheels is constrained to be optimal and thus a form of suspension with high performance positioning.

[0003] In general, however, multi-link suspensions suffer from stiffness issues, especially in configurations where the links are mounted via elastic bushings, as mentioned earlier. That is, when the wheel is subject...
