Strut and link nondrive rear independent suspension

(Fig. 10.50) With this suspension the wheel hub carrier's up and down motion is guided by the strut's sliding action which takes place between its piston and cylinder. The piston rod is anchored by a rubber pivot to the body structure and the cylinder member of the strut is rigidly attached to the wheel hub carrier (Fig. 10.50). A transverse link (wishbone arm) connects the lower part of the hub carrier to the body, thereby constraining all lateral movement between the wheels and body. The swing link arm and sliding strut member's individual movements combine in such a way that the hub carrier's vertical motion between bump and rebound produces very little change to the static wheel camber, either when the laden weight alters or when cornering forces cause the body to roll.

Braking fore and aft inertia forces are transmitted from the body to the hub carrier and wheel by trailing radius arms which are anchored at their e

Fig. 10.50 Strut and link non-drive independent rear suspension forward ends by rubber pin joints to the body under-structure. Owing to the trailing radius arms being linked between the body and the underside of each wheel hub carrier, deflection of the coil springs will cause a small variation in wheel toe-in to occur between the extremes in vertical movement.

The positioning of the body roll centre height will be largely influenced by the inclination of the swing arm relative to the horizontal; the slope of these transverse arms are usually therefore chosen so that the roll centre height is just above ground level.
