The suspension of a car is the system of springs, shock absorbers and linkages that connect a vehicle to its wheels.
The suspension consists of
that connect the car to its wheels.
The purpose of suspension systems is that it contributes to roadholding or handling and braking for good safety and driving pleasure, while keeping the occupants in a vehicle comfortable and reasonably isolated from road noise, bumps, and vibrations.
The suspension must keep the wheel in continuous contact with the road surface, because all the forces acting on the vehicle, do so through the contact patches of the tyres on the road. The suspension also protects the vehicle itself and any load from damage and wear.
A spring is an elastic object used to store mechanical energy. Springs are usually made out of spring steel.
A leaf spring is a simple form of spring that is used for the suspension in wheeled vehicles.
Coil springs or helical springs are used to absorb shock. Compression coil springs are usually used in cars.
C. Steering linkage, frame and control arm (wishbone) Steering is the term applied to the collection of components and linkages, which allows a vehicle to follow a desired course.
