Front

Fig. 1 Cross-sectional View Of Front Strut Assembly:

The front suspension consists of MacPherson struts with integral air springs and dual-damping shock absorbers, and two height sensors, one at each control arm.

The air suspension and dual damping functions are controlled by a microcomputer based module which receives inputs for vehicle speed, door switch position, damping actuator feedback, steering wheel turning rate and angle, engine vacuum, throttle position, brake actuation, ignition switching, and vehicle ride height. The dual-damping function automatically switches from a soft to firm ride when the driving situation (hard cornering, acceleration or braking, etc.) dictates the need for increased damping effect.

The front struts are mounted to the body through a precision ball bearing and rubber mount system. The ball bearing provides a durable pivot for the strut/wheel assembly, while the rubber mount provides for a smooth ride on rough roads with minimal noise. The rotary design Hall effect type height sensor, identical to the rear sensor, permits multiple height positions to be defined, resulting in specialized leveling during all types of driving and load characteristics.
