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.
TYPES AND DETAILS
There are two types of gas filled shock absorbers-
Mono tube with high pressure
Twin tube with low pressure
MONO TUBE
COMPONENTS:
Cylinder also called housing.
Piston connected to a piston rod.
Floating piston also called separating piston.
Piston rod guide.
Upper and lower attachment.
WORKING
The cylinder is not completely filled with
oil; the lower part contains nitrogen at
25-30 bar.
Gas and oil are separated by floating
piston.
REBOUND STROKE
When the piston rod is pulled out, the oil between piston and guide is forced to flow through the piston.
This resistance generates rebound damping.
At the same time part of piston rod will emerge from cylinder and free piston move upwards
TIPS BEFORE MOUNTING
Avoid stiff suspensions.
Avoid new shocks to compensate for
old and tired springs.
Worn shocks reduce safety and
handling.
The best advice come from a mechanic
who knows your vehicle.
