Independent rear wheel suspension.

摘要

An independent rear wheel suspension for a motor vehicle having front wheel drive includes a wheel support member (28) and two laterally extending control arms (20, 22) pivotably connected at their outboard ends to the wheel support member (28) and at their inboard ends to the vehicle chassis (10). The two laterally extending control arms (20,22) are longitudinally and vertically spaced apart. One arm (22) has an integrally formed spring seat (30) which seats a coil spring (31) interposed between the arm (22) and the vehicle chassis (10). A trailing arm (24) is rigidly connected to the wheel support member (28) and has its front end (50) connected to chassis (10) throuogh a resilient bushing (60).

The resilient bushing (60) has an outer sleeve (61) coaxially mounted about an inner sleeve (63) with layers of bonded elastomeric material (64) and coaxial rings (65) interposed therebetween and bonded to the inner and outer sleeves (61, 63). The central axis of the inner and outer sleeve are angled rearwardly and inboard. The outer sleeve (63) is axially fixed to the front end of the trailing arm (24) and can move axially against the resilient forces of the elastomeric material (64). As the wheel recesses, the bushing (66) allows the front end of the trailing arm to move inboard and promotes the wheel to toe-in during recession.
