The shock absorber used in the car has two-way drum absorber, inflatable shock absorber and adjustable resistance shock absorber 3 kinds.
　　Resistance adjustable shock absorber cylinder is equipped with a piston, the piston hole is equipped with a hollow connecting rod, the upper end of the hollow connecting rod fixed in the air chamber, the hollow rod is also equipped with plunger rod and plunger. The upper end of the plunger rod rests against the spring seat and the diaphragm. A spring is fitted between the spring seat and the plunger rod. The lower end of the hollow link has an orifice near the upper surface of the piston. As shown in Figure 4.
　　The resistance adjustable shock absorber is used on the suspension of the elastic element as an air spring. During operation, as the vehicle load increases, the air pressure in the air spring rises, and the air pressure in the chamber is also increased, and the diaphragm is pressed down until it equilibrates with the pressure generated by the spring. When the diaphragm moves down, the plunger rod and its lower plunger are pressed and moved down. When the plunger relative to the hollow link on the orifice position to reach the beginning of sealing, the orifice of the channel cross-sectional area began to decrease, so the amount of fluid through the orifice reduction, which increases the flow resistance of the oil. When the vehicle load is reduced, the plunger on the move, the orifice of the channel closure area increases, reducing the flow resistance of the oil.
