Independent Front Suspension System:

Purpose of Suspension System:

Due to a number of disadvantages of the beam or rigid axle front suspension, the manufacturers use an improvised version i.e. independent front suspension for passenger cars. However, earlier generation vehicles used rigid axle front suspension because of its simple design. It is also cheaper to manufacture and maintain.

Besides, its shock-absorbing property is poor which results in a bumpy ride and instability. Ideally, a good front suspension system should possess springiness and damping qualities.



Independent Front Suspension System:

In this system, the wheels connect to the frame in such a way that the movement of one wheel is not dependent on the other. Hence, each wheel acts as a separate suspension unit. The rise and fall of either wheel has no direct effect on the other. As a result, each wheel is able to maintain its level position regardless of the action of the other front wheel.

Today, most passenger cars use independent front suspension. It provides softer springing action, improved steering geometry and better bonding of wheels with the road. Additionally, this suspension improves the ride and handling qualities of the vehicle. Thus, it offers better ride comfort for the passengers.



Types of Independent Front Suspension System:

This system is also known as the parallelogram type suspension system. This is because the upper arm, lower arm, and stub axle form a shape of a parallelogram when connected. It consists of an upper arm and lower arm which attaches to the stub axle carrier or steering knuckle. Generally, the lower arm is larger than the upper arm and they may not be parallel.

1.Coil Springs type I: This design uses coil springs which provides springing action to the suspension. The spring sits between the upper and lower arms. The lower arm attaches to the frame at a single point.
