Description
Technical Field
The utility model relates to a bumper shock absorber technical field specifically is a no round pin bumper shock absorber that punches a hole.
Background
The principle of the existing double-cylinder shock absorber is that a floating piston is arranged at the lower part of a shock absorber cylinder barrel, so that a working chamber is formed into three parts. Filling high-pressure nitrogen into a chamber formed by the floating piston and one end of the cylinder barrel; the hydraulic oil of the shock absorber is arranged above the floating piston, and the floating piston is provided with an O-shaped sealing ring with a large section to completely separate the oil from the gas to form a gas sealing piston. When the wheel jumps, the working piston of the shock absorber reciprocates in the hydraulic oil, so that oil pressure difference is generated between an upper cavity and a lower cavity of the working piston, pressure oil pushes away a compression valve or an extension valve to flow back and forth, and the valve generates a large damping force on the pressure oil to attenuate the vibration. Due to the existence of high-pressure nitrogen in the lower cavity, the expansion and the compression of the nitrogen can be utilized, and the change of the volume of the cylinder barrel caused by the inlet and the outlet of the piston rod can be compensated by the up-and-down movement of the floating piston. The double-acting cylinder type shock absorber is provided with a working cylinder barrel and an oil storage cylinder barrel, so the double-cylinder type shock absorber is called.
At present, a conventional double-cylinder shock absorber is filled with high-pressure nitrogen gas and generally adopts a plate-type oil seal structure, the oil seal lip is formed by slotting with the aid of a gas needle or a piston rod, the pure rubber multi-lip oil seal is inconvenient to realize inflation, and most of the pure rubber multi-lip oil seal shock absorber is inflated at a bottom cover, so that the inflation difficulty is high.
