Shock Absorber (Absorber), suction rebound after the quake spring shock Absorber is mainly used to suppress the shock and impact from the road. While the shock spring can filter the vibration of the road, the spring itself has reciprocating motion, and the shock absorber is used to suppress the spring. The shock absorber is too soft, the car body will jump, the shock absorber too hard will bring too much resistance, prevent the spring normal work. In the process of about modification of the suspension system, the shock absorber of hard goes to the hard spring and the hardness of the spring and is closely related to vehicle weight, so the heavier car generally adopt a hard shock absorbers. A device that is connected to a crankshaft to counteract the torsional vibration of the crankshaft (that is, the crankshaft is twisted by the impact of the cylinder ignition).

Hydraulic shock absorber:

Hydraulic shock absorber is widely used in automobile suspension system. Its principle is that when the chassis and axle relative do reciprocating motion and the piston within the cylinder of shock absorber reciprocating movement, shock absorber in the shell oil has repeatedly from the inner chamber, through some narrow pore into another lumen. At this point, the friction between the liquid and the inner wall and the internal friction of the liquid molecules will form the damping force of the vibration.

Inflatable shock absorbers:

Inflatable shock absorbers are a new type of shock absorber developed since the 1960s. The structure is characterized by a floating piston in the lower part of the cylinder barrel, which is filled with high pressure nitrogen in an airtight chamber formed at the end of the floating piston and cylinder. The floating piston has a large section O ring seal, which separates oil and gas completely. The piston is fitted with a compression valve and an expansion valve that changes the area of the passage with the speed of its movement. When the wheel jumping up and down, shock absorber piston for work in the oil to do reciprocating motion, make the work of a piston cavity and produce oil pressure difference between inferior vena, pressure oil will open compression and stretching valves and flow back and forth. Because the valve has a large damping force on the pressure oil, the vibration attenuation.
