Shock Absorber Types for Car
Shock absorbers are devices that help to control the up-and-down movement of a vehicle. Without them, your car would ride very rough and be difficult to steer. Shock absorbers allow you to speed bumps with minimal effect on passengers. Different types of shock absorbers are available for cars, depending on the vehicle’s make and model. This article reviews three types of shock absorbers:
- Monotube design
- Twin-tube design
- External Reservoir Shock Absorbers
- Coil-Over Shock Absorbers
A monotube shock consists of a single tube. A piston and shock absorber hydraulic fluid is housed within the tube. These sorts of shocks have an exposed tube directly in contact with the environment. This makes them vulnerable to dirt and other road debris.
Twin-tube shocks are designed with two tubes: an outer tube that makes up the shock’s body and an inner one inside which the piston travels. When the shock is operating, oil flow via valves and holes in the piston.
A twin-tube shock absorber contains two separate tubes housing the piston and hydraulic fluid. The outer tube is separated from the inner one by an internal floating piston, which allows for much smoother movement than a monotube design. This type of shock offers improved comfort and handling over a monotube one.
External Reservoir Shock Absorbers:
An external reservoir shock absorber is also called an accumulator or air-cell shock absorber. It contains both the piston and hydraulic fluid within its outer tube, but there is no oil inside the inner tube.
Instead, this type of shock absorber contains an external hydraulic fluid reservoir. The extra space within the outer tube is used to hold pressurized oil, which provides damping force.
Coil-Over Shock Absorbers:
A Coil over shock absorber does not have a traditional shock body at all; instead, it consists of just two spring coils and shocks that attach directly to the vehicle. The increased ride height and spring travel make this type of shock absorber excellent for off-road vehicles.
What is Shock Absorber?
A shock absorber is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of an object into another form of energy (heat, sound), often dissipating it in the process.
The shock absorber is an instrument designed to lessen the effect of abrupt shock by the extravagance of the shock energy. On cars, motorbikes or similar automobiles, this device is planted to help the frame absorb the coming from the wheels.
While driving, we may face holes on the roads or speed breakers, the spring helps to cope with the shock by contracting and expanding. It comes into the act to stabilize the mainframe and do it by constricting the movement of the springs.
Hydraulic is the most preferred shock absorber in the case of automobiles. This type of absorber formation is of a casing that built of two tubes, both telescoping each other. Because of their telescoping feature, when a spring wants to contract or expand they must both push the bottom points.
As the ends of the damper shock are built to be highly resistant, the spring movement is quickly restricted. On some of the new technologies, hydraulic suspension works the part of both spring and absorber. Aircraft shock absorber working principle to reduce the risk factors of landing. On some machines, elastic materials are used in the making.
They lay aside the vibration generated by the machine acting as the shock absorber. One great example is the cork we see on bottles. Another name for a Shock absorber is Damper damper shock.
