Suspension (Rear suspension): Description and operation

REAR SUSPENSION

1. Hydragas unit
2. Damper unit
3. Upper suspension arm
4. Lower suspension arm

Suspension springing and damping is provided by the Hydragas unit mounted vertically above the upper suspension arm. An additional damper unit also vertically mounted to the upper suspension arm, is employed to provide a more responsive suspension. The damper unit assists in absorbing the energy stored in the Hydragas unit after passing a bump. Quickly terminating the reciprocating motion of the suspension and returning the Hydragas unit to the rest position.

5. Tie bar
6. Anti-roll bar
7. Adjustable track control arm

The track control arm and lower arm make up the suspension wishbone to provide the necessary fore-and-aft stiffness to resist braking torque. A tie bar fitted between the lower arm and the front of the subframe, resists longitudinal dynamic loads and braking torque. Both upper suspension arms are interconnected by an anti-roll bar which provides the required stiffness to prevent body roll.
