What Are the Shock Absorber Components and Different Types?

 Shock Absorber Types

Shock absorbers are mechanical devices that are used to absorb the energy of sudden impulses or shocks in machinery or structures.

When the vehicle encounters a bump, the lower eye opens. As a result, fluid from the lower side valves flows through to the upper side, but because the volume of the space above the valve is less than the volume of the rod, the fluid exerts pressure on another valve. The damping forces are determined by the pressure of the fluid valves as they open. As a result, when the lower eye moves down, fluid flows from the upper side of the valves to the lower side and vice versa.

The shock absorber must be refilled with shock absorber fluid at the manufacturer's recommended intervals during a car service in Reading. When its condition necessitates it. The service of modern telescopic shock absorbers is no longer available. They should be replaced if they leak or do not provide adequate resistance to push and pull.

Shock Absorber Components

Shock absorbers differ in design and operation, but the main components are the same. The following are some shock absorber components:

• Valve
• Valve springs
• Piston
• Linkage

1.     Mount for Shock Absorbers 

      Shock absorber mounts secure shocks to the mechanical body and suspension. It could be an upper or lower mount.

2.     Brush for Shock Absorber

      Shock absorber brushes are typically found on the mounting. Rubber or urethane absorber brushes are used. To prevent noise and wear, an absorber brush absorbs vibration and separates metal parts.

3.     Coil Springs for Shock Absorbers

      The coil spring is a component of the shock absorber assembly, also known as the coil over shock absorber.

4.     Piston Shock Absorber & Piston Rod

      The piston rod of a shock absorber contains valves or openings. The piston rod component guides the piston within the shock absorber cylinder.

5.     Cylinder of Shock Absorber

      The shock absorber cylinder is the tube that makes up the shock absorber's body. It primarily contains compression oil and serves as the tube through which the shock absorber piston moves.

Telescopic Shock Absorber Construction

The upper eye is attached to the axle, while the lower eye is attached to the chassis frame. A two-way valve is attached to the rod, and another two-way valve is connected to the lower end of the cylinder.

What Are the Different Types of Shock Absorbers?

The following are some of the most common types of shock absorbers:

1.     Shock Absorber of the Hydraulic Kind

      These are mostly found in passenger vehicles. They resist spring action by forcing a fluid through check valves and small holes. They operate on the principle of converting kinetic energy into thermal (heat) energy. When force is applied to the shock absorber, fluid flows through the outlet and valve system, producing hydraulic resistance.

2.     Shock Absorbers with Dual Action

      A double-acting shock absorber provides resistance during both compression and rebound holes. They are commonly found on modern vehicles and have the ability to use highly flexible springs.

3.     Shock Absorbers with a Single Action

      During operation, they only produce resistance at the rebounding stage.

4.     Shock Absorber with Friction

      Because of the unpredictability of damping characteristics, friction type shock absorbers have become almost obsolete (outdated).

5.     Shock Absorber with a Lever

      Lever types are of the indirect variety. They are made up of levers and links that are bolted to the chassis. A double piston arrangement forces oil through a valve as the axle moves up and down. They are used in car suspension devices that use hydraulic oil, and the resistance forces increase as the speed increases. This results in improved damping characteristics for longer suspension bumps.

6.     Shock Absorber of the Telescopic Type

      Telescopic types are of the direct variety. It is essentially mounted between the axle and the frame. They have the ability to be compressed or extended. They are classified as bi-tube or twin-tube dampers.

Shock absorbers are an important component of a vehicle's suspension. The purpose of a shock absorber is to absorb or dampen the compression and rebound of the springs and suspension. They are in charge of reducing unwanted and excessive spring motion. Shock absorbers keep your tyres in constant contact with the road.
