Hello, Guys, I am here with a post about suspensions of vehicles. The suspension is the most important component of the car for stability and comfort. Suspension maximizes the friction between the road and tries for good handling.

If the road were flat without any irregularities, there would be no requirement of suspension. But our roads are filled with bumps and irregularities which implies force on tries, therefore suspension is must to keep the car on the road with good friction.

The bumps cause the wheels to move in perpendicular motion which causes vertical acceleration. This motion transfers the force to the body frame, the downward gravity slams the wheel back into the road surface. As a result, the tyre will lose contact with the road.

1) Independent Suspension :

This kind of suspension allows each wheel on the same axle to move independently in a vertical position when moving in an uneven surface. This way a force on the wheel will not affect the other wheel cause they are not mechanically connected. In most of the vehicle, it is mounted on the front wheels.

This kind of suspension provides good ride quality and handling due to less un-sprung weight. It requires less space and it is lightweight which provides better steerability.

Types of Independent Suspension :

MacPherson Strut

It is an independent type of suspension, got its name from Earle S. McPherson who developed this design. It is a very popular suspension, because of its simplicity and low manufacturing cost. They have a low un-sprung weight which helps in low vehicle weight and comfortable ride.

The disadvantage is that it is more difficult to insulate against road-noise, for this an upper strut mount is necessary, which should be decoupled as possible. It also requires greater clearance height.

Double wishbone/A-ARM

It is also a type of independent suspension with two wishbone-shaped arms. Each wishbone has two mounting points to the chassis and one joint at the knuckle. The angle movements of the compressing and rebounding wheels can be managed by using arms of unequal length.

This allows easy adjustment of camber, toe and other parts of the suspension. This type of suspension also provides increasing negative camber gain all the way to full bounce travel.

It has a design limit and takes more space and it is more complex than the other system like Macpherson strut.

Type of Dependent Suspension :

Independent Suspension there a linkage between the two-wheel on the same axle, the force acting on one wheel will also affect on the other wheel on the same axle. It is mostly used on heavy vehicles. It can bear shocks with a great capacity than independent suspension.

Solid Axle

It is one of the types of dependent suspension. It is mostly used in rear wheels. The vertical movement of one wheel influences the other, because of this it can lose control when the vehicle is turning.

There are various ways for a solid axle. One it has two leaf spring supporting the rear axle. Leaf spring is mostly used in trucks or heavy vehicles, it is not very good suspension but a cheap option to use and durable.

Trailing control arm is a good option as it prevents the axle from side movement and front & back movement because it is connected to chassis and the axle.

It is the most durable suspension system.

There are various other types of suspension but these are the most used systems.
