Bidirectional action cylinder shock absorber
The working principle of two way cylinder shock absorber is explained. In the compression stroke, refers to the car wheels close to the body, the shock absorber is compressed, at this time the piston in the shock absorber moves downward. The volume of the lower chamber of the piston decreases, the oil pressure rises, and the oil flows through the flow valve to the chamber (upper chamber) above the piston. The upper chamber is partially occupied by the piston rod, so the increased volume of the upper chamber is less than the reduced volume of the lower chamber. These valves save oil and form the damping force of the suspension subjected to compression. When the shock absorber extends the stroke, the wheel is equivalent to far away from the body, and the shock absorber is stretched. The piston of the shock absorber moves upward. The piston upper chamber oil pressure rises, the circulation valve closes, the upper chamber oil pushes the extension valve to flow into the lower chamber. Because of the existence of the piston rod, the oil flowing from the upper chamber is not enough to fill the increased volume of the lower chamber, and the main cause of the lower chamber to produce a vacuum, when the oil in the tank pushes the compensation valve to flow into the lower chamber to supplement. Because of the throttling effect of these valves, the suspension plays a damping role in stretching motion.
Because the spring stiffness and pre-tightening force of the expansion valve are designed to be greater than that of the compression valve, under the same pressure, the total load area of the expansion valve and the corresponding normal opening channel is less than that of the compression valve and the corresponding normal opening channel. This makes the damping force produced by the stretching stroke of the shock absorber is greater than the damping force produced by the compression stroke, and meets the requirements of rapid vibration reduction.
