Suspension

The suspension is the link between the road and the car body. The job of the suspension is to reduce, as far as possible in a controlled fashion, the vibrations from the wheel and the car body caused by an uneven road or changes of direction. Every attempt must be made to prevent these vibrations from being transmitted to the car body in order to reduce rocking, pitching and diving, avoid swaying, and ensure optimum road contact and traction with minimum slip. The suspension system comprises a range of components, including strut support bearings, springs, shock absorbers, connecting rods (coupling rods), stabilisers, axle supports, wheel bearings, suspension arms (control arms and pull rods), wheel brakes, rims, tyres, final drives and steering.

Shock absorbers and how they work

The shock absorbers reduce and slow down the vibrations from the springs, which is why technically they are correctly referred to as vibration dampers. Vibration dampers convert kinetic energy into thermal energy through fluid friction. This involves the flow of oil being slowed down by the valve passages inside the damper.

Hydraulic Shock Absorber

The hydraulic shock absorber provides its dampening action by transferring oil, under pressure, through valves which restrict the oil flow.

The dampening action of a hydraulic shock absorber comes from transferring oil, under pressure, through valves that restrict the oil flow. Resistance to motion is low when the piston moves slowly and high when its velocity is high.
