Shock absorbers are one of the most important components in your car. They protect vehicles and passengers from unwanted kicks or vibrations that happened due to road bumps. They make the movement of the vehicle smoothly and make the journey comfortable for the occupants.
Various types of Suspension & Shock Absorbers are available, each of which has its own function depending on the needs of the vehicle. We briefly discuss some of them.

Main Double Tube:
The double tube contains two cylindrical tubes that are inserted such as the working tube and the tank. Both pipes contain hydraulic fluid. A piston is inserted into the inner tube and the piston cap has small holes so that the hydraulic fluid can move when the piston moves back and forth. The shock energy is then converted into heat and dissipated. The dual-tube shock absorbers are as follows:
The Double Tube Is Filled With Gas:
In this case, nitrogen gas is used in the tank instead of hydraulic fluid. This is a significant improvement over the main dual-tube as it eliminates problems such as ventilation and foaming, as well as the discharge of hydraulic fluid from the tube caused by piston action. Due to this prevention, excess heat is greatly reduced.
Sensitive Position Shock Absorbent
The sensitive position damping system includes two additional grooves so that the piston moves freely over the tube when the vehicle is traveling on a smooth surface. At the same time, movement is hampered when the vehicle is traveling on uneven surfaces where the up and down motion of the piston is more intense. These new advancements in shock absorber systems have allowed car designers to build shock absorbers based on size, weight, maneuverability, etc. from the car.
Unlike the twin-tube shock absorber, the single tube shock absorber does not have a tank. When the piston is pressed, the hydraulic fluid must be moved firmly. This is controlled when the fluid adapts to pressure. This is achieved by filling the bottom of the tube with nitrogen gas. The hydraulic fluid and nitrogen gas are separated by a "floating piston".
