Rear Suspension: Overview

Rear Suspension

OVERVIEW
The double wishbone type rear suspension is a fully independent design assembled on a steel subframe. Large diameter bushes isolate the subframe from the vehicle's body.
Toe links, installed between the wheel knuckles and the subframe, are used to adjust the toe angle of the rear wheels.
The wheel knuckles are attached to the upper and lower control arms. A spring and damper assembly is located between each lower control arm and the vehicle body.
The spring and damper assemblies incorporate air springs controlled by the air suspension system.

Air Suspension System
The air suspension system provides a fully automatic self-leveling function that ensures the vehicle maintains a constant attitude, irrespective of load, by adjusting the rear ride height to match the front ride height.
The air suspension system comprises of:
- An air spring in the spring and damper assembly of each rear wheel.
- An air compressor assembly.
- A valve block.
- A reservoir.
- A silencer.
- A network of pipes to connect the individual components.
- Four suspension height sensors (one for each corner of the vehicle).
- An air suspension module.
