The spring rate is the rate of the spring and damper measured at the damper. The wheel rate is the rate the tyre is going to see and this is dictated by the motion ratio and spring rate. Let us know discuss the mechanics of how to calculate the wheel rate.
There are three basic types of suspension components: linkages, springs, and shock absorbers. The linkages are the bars and brackets that support the wheels, springs and shock absorbers. Springs cushion the vehicle by dampening shock loads from bumps and holes in the road.
A car suspension acts as a spring-mass-dashpot system on each wheel. This allows the car to stay on the road and enable good handling of the car under normal driving conditions. We examine a \quarter car" model that involves a second order di erential equation for one wheel.

The main function of the dampers is to control the transient behavior of the sprung and unsprung masses of the vehicle. This is accomplished by damping the energy stored in the springs from suspension movement. The damper generates a force defined by the characteristic curve and the velocity of the damper.
The primary function of the damper on the vehicle is to damp the sprung and unsprung masses at their resonant frequencies. For the sprung mass, this includes the pitch, heave and roll resonant frequencies.
