Shock absorbers support the springs by converting vibration energy into heat. In this way, the body reaches its rest position much faster than without additional damping. Today, almost exclusively hydraulic vibration dampers are used in the automotive sector, in which a piston moves in a cylinder and forces oil or gas through small bores or valves. By changing the resistance, shock absorbers can be adapted to the vehicle properties. Modern shock absorbers are even electronically adjustable and allow comfortable or sporty damping, as well as adjustments to the load condition of the car.
