Spring And Shock Absorber Assembly

Spring 

The coil spring fitted differs with vehicle specification; each spring is color coded to identify its rating and fitment requirements. The spring assembly is supplied with the upper and lower isolators attached.

The lower end of the coil spring is located in the lower control arm which contains a feature for orientating the spring assembly. The design of the lower isolator prevents the spring rotating. The spring has a linear rate compression and is inclined to counter cornering forces.

The upper-end of the coil spring is also located in a spring isolator underneath the vehicle's body member. Both upper and lower spring isolators are made from rubber and reduce any noise produced during shock absorber and spring compression and extension, from being transmitted to the vehicle body.

Shock Absorber 

The shock absorber assembly is a mono-tube design; the lower end of the shock absorber is fitted with a bush and is attached to the wheel knuckle. The shock absorber top mounting is secured to the vehicle's body.

The shock absorber functions by restricting the flow of hydraulic fluid through internal galleries within the shock absorber. The shock absorber rod moves axially within the shock absorber, its movement limited by the flow of fluid through the galleries, providing damping of undulations in the terrain. The shock absorber rod is sealed at its exit point from the shock absorber body to maintain the fluid within the unit and to prevent the ingress of dirt and moisture. The seal also incorporates a wiper to keep the rod clean.

The threaded outer end of the shock absorber rod locates through a hole in the top mount. A self-locking nut secures the top mount to the shock absorber rod. The shock absorber rod on the adaptive shock absorber has an electrical connector integrated to the end of the shock absorber rod. For additional information, Refer to: VEHICLE DYNAMIC SUSPENSION
