Main Functions

Featuring a basic structure made up of pistons, cylinders, hydraulic oil and valves that work under load alongside steel springs, this shock absorber generates buffering resistance as hydraulic oil flows through throttling holes: on compression strokes when wheels rise upward, the descending piston pushes oil through orifices to cushion impacts; on rebound strokes when springs reset and pistons travel backward, reverse oil flow restrains quick spring rebound. Its core function transforms mechanical energy from road vibration into dissipated thermal energy to eliminate persistent vehicle shaking and boost driving stability, yet its fixed stiffness, rigidity and ride height restrict automatic adjustment based on varying road surfaces or driving speeds.
