Q-1 How Shock Absorber Works?
Ans- Shock absorber functions against hydraulic fluid in the
pressure tube. They are generally attached at the end of the piston. The up
and down movement of the piston forces the hydraulic fluid through minute
holes inside the piston. The fluid insertion reduces the speed of the piston
thereby slowing down the piston, which in turn slows down spring and
suspension movement.
Q-2 What is a Twin Tube Shock
Absorber?
Ans- Twin tube shock absorber consists of tube inside the outer
shock body. It is basically a low pressure shock. The tube contains the
piston assembly. The coil spring inside the shock body are used to create
damping force. Outer tube of the shock absorber is called as reserve tube
containing hydraulic fluid.
Q-3 What is Mono Tube Shock
Absorber?
Ans- Mono tube shock absorber functions by regulating the oil flow
between the compression and compensation chambers by using mechanically
fixed base valve. Mono tube design, utilizes the deflective discs for
creating the damping force.
Q-4 How Gas Shock Absorber
Works?
Ans- In gas shock absorber, at the end of the piston, gas (Nitrogen
gas) is used. The use of gas prevents aeration of the oil and reduces
foaming and hence increase the performance of the shock absorber.
Q-5 What can effect shock
absorbers durability?
Ans- Some of the solutions that can enhance both the functions and
life of the shock absorbers are: Side load submersion in radio active waste
- Submersion and pressurization sub sea
- Pressure wash down
- Extraordinary impact force or velocity
- Localized welding heat or splatter etc.
Q-6 Is it possible to use
only part of the shock absorber stroke?
Ans- Yes you can use only part of the stroke but it is recommended
that you use the last part. The reason is that using the stroke up to the
end of the stroke will provide you a linear deceleration effect thereby
bringing the mass close to rest. But you won't be able to use the full
energy capacity available or the lowest deceleration rate.
Q-7 Can I use my shock absorbers
at very high ambient temperatures?
Ans- Using shock absorber in ambient temperatures our above the
desired limits, the hydraulic fluid starts to break down. This can result in
the expansion of the encapsulated air in the return accumulator.
Subsequently the rod seals start to melt and the shock absorber loses its
fluid. This finally results in the failure of your shock absorber.
Q-8 What is a telescopic shock
absorber?
Ans- Today most of the vehicles use telescopic shock absorber. It is
an important shock absorber that can be compressed and extended into bump
stroke and rebound stroke. Nowadays most of the telescopic shock absorber
are configured into double acting, which means hydraulic resistance in both
bump and rebound.
Q-9 What is coil over shock
absorber?
Ans- In coil shock absorber spring and shock absorber are assembled
as a single unit. If any problem arises in the spring then the shock
absorber is replaced as a unit. It is an effective device that is known for
its effective damping without torsional loads.
