What is an inflatable shock absorber

The working cylinder is equipped with a working piston and a floating piston. The working piston is on the top and the floating piston is on the bottom. The working cylinder is divided into three parts. The closed gas chamber formed between the lower part of the floating piston and the cylinder is filled with high-pressure nitrogen. A large-section O-ring seal at the edge of the floating piston separates the oil above the floating piston from the nitrogen below. The working piston is provided with a compression valve and an expansion valve that can change the passage flow area with the change of the piston movement speed. Both valves are composed of a group of spring steel sheets with the same thickness and different diameters, arranged from large to small.China electric scooter shock absorber

 

When the wheel moves relative to the frame, the working piston reciprocates in the oil, causing an oil pressure difference between the upper and lower chambers of the working piston, and then the pressure oil pushes the compression valve or the expansion valve back and forth to flow. Because the valve generates a large damping force on the pressure oil, the vibration is attenuated. The cylinder volume change caused by the presence of the piston rod is compensated by the up and down movement of the floating piston.

The upper end of the hollow connecting rod is fixed on the lower shell of the air chamber. A plunger rod and a plunger are also installed in the hollow connecting rod. The upper end of the plunger rod bears against the spring seat and the diaphragm. A spring is installed between the spring seat and the plunger rod. The lower end of the hollow connecting rod is provided with a throttle hole near the upper surface of the piston
