Types of shock absorbers
Although all shock absorbers do the same job, different types of vehicles and suspension designs require different types of shock absorbers which can appear radically different.
No matter the application, they fit into one of three broadly defined types:
- Conventional telescopic shock absorbers
- Struts or spring seat shocks
COIL SPRINGS SUSPENSION
The springs in your vehicle’s suspension system work with your struts and shocks to absorb road impact, support the weight of your vehicle, and keep all four of your wheels planted on the ground. How tightly springs are wound and the stiffness of the suspension springs used can also have an effect on a car’s handling performance, ride smoothness and correct ground clearance.
Torsion bars and leaf springs can be found on trucks, heavy-duty vehicles, and automobiles that predate 1985. The most common type of suspension springs used on vehicles today is coil springs.
SUSPENSION Rubber Bushes
Rubber bushes is a type of vibration isolator. It provides an interface between two parts, damping the energy transmitted through the bushing. A common application is in vehicle suspension systems, where a bushing made of rubber (or, more often, synthetic rubber or polyurethane) separates the faces of two metal objects while allowing a certain amount of movement. This movement allows the suspension parts to move freely, for example, when travelling over a large bump, while minimizing transmission of noise and small vibrations through to the chassis of the vehicle. A rubber bushing may also be described as a flexible mounting or antivibration mounting.
