car Suspension System

car suspension system

This project Dept of Mechanical Engineering Final Year Project presents the independent suspension which deals about the automobile suspension system providing the wheels to move in the vertical position. The movement depends on live axle and beam axle that affect both the wheels. The left and right suspension spring are tied by anti-roll bar. Many vehicles possess independent front suspension (IFS) and independent rear suspension (IRS). IRS includes rear wheels sprung.

The important thing for lower unsprung weight is for driven wheels. The motion between the wheels and the differential is by using swinging drive shafts linked by universal (U) joints and analogous to the constant-velocity (CV) joints.

Vehicle dynamics is defined as the forces provided on a movable car. There are two views considered by automobile engineers for moving car are RIDE and HANDLING. Ride is the ability of a car to move on a rough road and handling is ability of a car to drive safely brake, accelerate, and corner.

There are four kinds of suspension. They are conventional suspension system, independent suspension system, air suspension system, and hydro-elastic suspension system.

The system has no reaction on steering. It needs major distance to stop rolling action. The front axle provides better road holding tendency of tyres. There is less vibration. It offers smooth ride and rear wheels are stable.


Typically, the project on independent suspension systems provides the good ride characteristics and quality because of lower unsprung weight. IRS makes the wheel to jump on a hard land. The system needs expenses and engineering effort for live axle arrangement. IRS offers great manufacturing rates.
