Car Shock
absorbers along with the struts helps in keeping the tyres firmly on the
road and hence give the driver smooth and pleasant drive. Shock absorbers
along with suspension, are used to provide smoother pivots. They are used
for dampening the up and down oscillation of the car's leaf springs. The
principle behind the working is simple that it ease out the shock impact to
disperse kinetic energy by changing motion into heat.
In different cars different types of shock absorber. Shock absorber used in
cars are determined largely by the car's construction, set up, race track
qualities, driving dynamics and weight allocation. Improvement in the
bonding of the chassis movement and weight transfer improves the performance
and driving dynamics of the car. The shock value differ from car to car. The
shock value is design to provide maximum speed to the car and the distinct
driving style to the driver.
Working of Car Shock Absorber
The principle on which the shock absorber works is that it moves the spring
and convert the kinetic energy into heat. There is a piston rod that works
with the hydraulic fluid on the car's pressure tube. The movement of the
suspension forces the hydraulic fluid to the tiny holes inside the piston
however as the hole is small, the piston slows down and reduce the movement
of the suspension and spring.
The resistance depends on the quantity and size of the holes or orifices in
the piston and the suspension's movement. Many car uses very advanced shock
absorbers having velocity hydraulic damping devices. This lead to the speedy
movement of the suspension in order to attain greater resistance.
There are different designs in which car shock absorbers are available. The
most popular shock absorber are twin tube designs and mono tube designs.
There are two tubes in twin tube shock absorber. It consists of an inner and
outer tube which work together for achieving the intended purpose. Mono tube
on the other hand consists of single tube which is mounted in an upside down
position to decrease weight. Some of the shock absorber also comes with
nitrogen gas at the end of the piston which reduce foaming and increase the
performance.
For racing purpose Shock absorbers are essential in order to reach optimum
speed and performance. For racing purpose, shock absorbers come in various
disk designs and valve combinations.
The factors which should be considered for achieving proper shock absorber
positioning are:
- Rebound resistance from within the shock.
- Compression pressure inside the shocks.
- Distance rearward from the axle.
- Arc of travel from the car's locating arms.
- The compression or rebound travel.
The effectiveness of its purpose is also dependent upon its location.
For cars equipped with suspension that moves up and down like Ford, shock
absorbers must be mounted on the outboard as close as possible on the ball
joints. The versatility of Ford shock absorbers allows easier adjustment to
cope with various road conditions. The location of shock absorbers may
depend upon the specifications and features of the car.
Shock absorber replacements must be of right size and length especially for
Ford auto makes. Mercedes Benz shock absorber is a piece of equipment used
at each wheel of the suspension system to help control the up, down, and
rolling motion of a car body by simply dampening the oscillations or jounce
of the springs when the vehicle goes over bumps. Without this thing, the car
occupants will truly have a bad experience especially when traversing rocky
roads. All vehicles are equipped with shock absorbers because they work a
very significant job.
