INTRODUCTION
For a smooth and comfortable ride the disturbing forces should be
eliminated or reduced considerably by using some devices. Shock
absorbers are such devices which isolate the vibrations by absorbing some
disturbing energy themselves. Of the many types telescopic shocks are
widely used which has got the draw back that the flow of oil in the cylinder
can cause foam of oil and air to form. These limit the optimum throughout
of the flow in the valves. Gas shocks represent an advance over traditional
shocks. Nitrogen filled gas shock absorbers are the results of years of
extensive research and development with top flight shock design
engineers. They are designed for both lowered and stock vehicles to
provide shock absorbers that would out perform anything on the market
today. Nitro shock absorbers are high quality, nitrogen filled shocks
designed and gas charged specifically for each vehicle application. The
addition of nitrogen under pressure limits the foaming effect and increases
efficiency
NEED FOR SHOCK ABSORBER
Springs alone cannot provide a satisfactorily smooth ride. Therefore an
additional device called a “shock absorber” is used with each spring.
Consider the action of a coil spring. The spring is under an initial load
provided by the weight of the vehicle. This gives the spring an original
amount of compression. When the wheel passes over a bump, the spring
becomes further compressed. After the bump is passed the spring attempts
to return to its original position. However it over rides its original position
and expands too much. This behaviour causes the vehicle frame to be
thrown upward. Having expanded too much, the spring attempts to
compress that it will return to its original position; but in compressing it
again overrides. In doing this the wheel may be raised clear of the road and
the frame consequently drops. The result is an oscillating motion of the
spring that causes the wheel to rebound or bounce up and down several
times, after a bump is encountered. If, in the mean time, another bump is
encountered, a second series of rebounding will be started. On a bumpy
road, and particularly in rounding a curve, the oscillations might be so
serious as to cause the driver to lose control of the vehicle.
WHY GAS FILLED SHOCK ABSORBERS?
he rapid movement of the fluid between the chambers during the
rebound and compression strokes can cause foaming of the fluid. Foaming
is the mixing of free air and the shock fluid. When foaming occurs, the
shock develops a lag because the piston is moving through an air pocket
that offers up resistance. The foaming results in a decrease of the damping
forces and a loss of spring control.
During the movement of the piston rod, the fluid id forced through the
valuing of the piston. When the piston rod is moving quickly, the shock
absorbers oil cannot get through the valuing fast enough, which causes
pressure increases in front of the piston and pressure decreases behind the
piston. The result is foaming and a loss of shock absorb
CONCLUSION
In the current scenario of automobile industry the need for vehicles which
provides smooth and comfort ride is growing. Nitro shock absorbers are
designed to be ultimate in performance and comfort. In a country like ours
whose roads are not up to world standards the need for automotive
components like nitro shocks are necessary. It goes without saying that if
the right choice is made the improvements in vehicles ride and handling
can be shockin
