    THE SUSPENTION SYSTEM (GENERAL CONSTRUCTION)

    The basic construction consists of: SRINNG, SHOCK ABSOBER, ARM MECHANISM and

    STABLIZER.

    SPRING: Relieve the up and down movement of the car due to the road surface irregularities.ARM MECHANISM :Support the vehicle weight and wheel movement.SHOCK-ABSORBER: Absorb up and down spring oscillation or vibration.

    STABLIZER: To prevent rolling especially when cornering, it also tends to reduce wheel

    wobbling, but has little effect on spring stiffness.

    SPRINGS

    Mainly three types are used.

    1.  Leaf spring. Which is long flat at ends, elliptic in shape. Sometimes one or few leafs are bound together. (here the springing action is by bending.)

    2.  Coil Spring. (action is by spring compression)

    3. 

    Torsion Bar. To this type one end is fitted on the lower wishbone and the other on theframe through the lever. (action here is by Twisting force.)

    The Suspension can be classified by two types:

    1.  Rigid axle type or

    2.  Independent type.
