SACHS rear cabin suspension shock absorber
Sachs OE number 290 202

A cabin shock absorber in a car is primarily responsible for reducing the impact and vibrations experienced by the passengers inside the cabin. It is designed to absorb the shocks and bumps from uneven road surfaces, potholes, and other obstacles encountered during the vehicle's movement. By doing so, it enhances the comfort and safety of the passengers by preventing excessive jolts and vibrations that may cause discomfort or fatigue. The cabin shock absorber works in conjunction with the suspension system to maintain stability, control, and smoothness in the car's ride quality.

The main function of the cabin shock absorber is to dampen the energy generated from the vertical movement of the wheels. It does this by converting the kinetic energy into heat energy through the hydraulic or gas compression mechanism. This process involves a piston that moves up and down within a cylinder filled with hydraulic oil or gas. When the wheel encounters an impact, the piston compresses the oil or gas, which absorbs the shock and prevents the sudden transmission of force to the cabin. The dampened energy is then dissipated as heat, allowing for a controlled rebound and reducing the oscillations in the cabin. Overall, the cabin shock absorber plays a vital role in providing a smooth and comfortable ride experience for the occupants of the car.
