The principle of air shock absorber

1. Automotive air-type shock absorbers are called shock absorbers, which control unwanted spring movement through a process called damping. A shock absorber slows and dampens the magnitude of vibratory motion by converting the kinetic energy of suspension motion into thermal energy that can be dissipated by hydraulic fluid. To understand how it works, it is best to look at the structure and function inside the shock absorber;

2. The shock absorber is basically an oil pump placed between the frame and the wheels. The upper mount of the shock absorber is attached to the frame (i.e. sprung mass) and the lower mount is attached to the axle near the wheel (i.e. unsprung mass). In dual-barrel designs, one of the most common types of shock absorbers has the upper mount attached to the piston rod, which is attached to the piston, which sits in a cylinder filled with hydraulic oil. The inner cylinder is called the pressure cylinder, and the outer cylinder is called the oil storage cylinder. The oil storage tank stores the excess hydraulic oil;

3. When the wheel encounters a bumpy road and causes the spring to be compressed and stretched, the energy of the spring is transmitted to the shock absorber through the upper support, and is transmitted down to the piston through the piston rod. There are holes in the piston, and when the piston moves up and down in the pressure cylinder, the hydraulic oil can leak out through these small holes. Because these holes are so tiny, very little hydraulic fluid can pass through under high pressure. This slows down the movement of the piston, which in turn slows down the movement of the spring.
