The suspension system

Suspension is a collection of individual components functioning dampen shock, vibration that occurs in vehicle due to an uneven road surface which can enhance driving comfort and vehicle control. Vehicle suspension system is located between the body (skeleton) with wheels. There are two main types of suspension are:

1. The suspension system dependent or rigid axle suspension system (rigid)
2. Independent suspension system or independent suspension system.

The suspension system dependent

Wheels in a shaft connected to the shaft stiff (rigid), rigid shaft is connected to the body by using springs, shock absorbers and control arm (control arm)

Initially all vehicles using this system. Until now most of the heavy vehicles such as trucks, still use this system, while commercial vehicles generally use this system on the rear wheels.
Independent suspension system

Between the wheel in one axis are not directly connected, each wheel (left and right wheels) is connected to the body or frame to the suspension arms (suspension arm), springs and shock absorbers. Shock or vibration in one of the wheels does not affect the other wheel.

Generally passenger vehicles use this system for all wheel axles, while commercial vehicles generally use this system on the front wheels, while the rear axle suspension system uses dependent on the rear axle. Type MacPherson strut and double-wishbone included in this type of system.

THE MAIN COMPONENTS

spring

With the elastic properties of springs, spring serves to receive wheel vibration or shock result of the condition of the road in order to vibration or shaking of the wheel is not channeling the vehicle body or frame.

Some types of springs used in the suspension system:

> Screw spring (coil spring), also known as 'a snail', the type used is a spring or spring-threaded screw press to accept compressive load.> Spring leaf (leaf spring), commonly used on heavy or commercial vehicles with a suspension system dependent.> Torsional spring or known as torsion bar springs (torsion bar spring), commonly used on vehicles with a load is not too heavy.

shock absorbers

Shock absorbers serve to dampen shock loads or vibrations or shocks received by spring.

suspension sleeve

Suspension arm or suspension arm only in dependent suspension system, mounted on the vehicle body or frame, is used to hold the frame wheel vehicles. Complex movements on the wheel in order to sync with the movement of the movement of the suspension arms are ball joint suspension arms on the binding framework of wheels.
