NEED FOR SHOCK ABSORBERS
Springs alone cannot provide a
satisfactorily smooth ride.
Oscillation of spring causes the wheel to
rebound, or bounce up and down.
Control over the vehicle can be lost.
Shock absorbers prevent these spring
oscillations.
HOW IT WORKS?
All shock absorbers use hydraulic fluid to convert the energy of the spring to heat.
Consists of two strokes
Compression &
Rebound
WHY GAS FILLED SHOCKS?
Rapid movement of the fluid between the chambers cause foaming.
Results in a lag because the piston moves through an air pocket which offers resistance.
Foaming results in a decrease of damping and a loss of spring control.
GAS FILLED SHOCKS
Designed to reduce foaming of the oil.
Construction is similar except the double tube, here a dividing piston is used.
Two chambers – oil & gas.
TYPES AND DETAILS
There are two types of gas filled shock absorbers-
Mono tube with high pressure
Twin tube with low pressure
