Suspension is the term given to the system of springs, shock absorbers and linkages. The suspension acts as an intermediate between the car and the road and solves several problems:
- Transfer to the frame or body of forces and moments arising from the interaction of wheels with the road surface;
- Link wheels with body or frame;
- Provides the necessary for the normal movement of the position of the wheels relative to the frame or body and the road;
- Ensures acceptable running smoothness, compensates for uneven pavement.
So a car suspension is not just a set of components for connecting wheels and body or frame, but a complex system that makes normal and comfortable movement on car driving.
