Suspension system

Hi guys, this is Pushan Mohanta and today I am writing on suspension system. In last blog I discussed about braking system.


Suspension is the system of tires,tires air,springs,shock absorbers and linkages that connects a vehicle to its wheels and allow relative motion between the two.

Basic parts

Control Arm-
                        Movable lever that fasten the steering knuckle to the vehicle body or frame.

Steering knuckle-
                                Provides a spindle or bearing support for the wheel hub, bearings and wheel assembly.

Ball joints-
                   Swivel joints that allow control arm and steering knuckle to move up and down and side to side.

 Springs-
                Supports the weight of the vehicle;permits the control arm and wheel to move up and down.

Shock absorbers or dampener-
                                                         Keeps the suspension from continuing to bounce after spring compression and extension.

Control arm bushing-
                                       Sleeves that allows the control arm to swing up and down on the frame.

Let's discuss that suspension system, there are two types of systems

Non-independent suspension-
                                                       Both right and left wheel attached to the same solid axle.when one wheel hits a bump in the road,it's upward movement causes a slight tilts of the other wheel.

Independent suspension-
                                               Allows one wheel to move up and down with minimal effect to the other.

For any enquiry or any other requirement or to explain any part of it you can add a comment

Thank you
