Abstract

The invention discloses an air-compression vehicle shock absorber, which comprises an upper cylinder, a lower cylinder and a baffle between the upper cylinder and the lower cylinder, wherein two air compression tubes are fixed in the center inside the upper cylinder and the lower cylinder respectively; a piston rod is arranged in each air compression tube; one end of each piston rod is connected with a gas piston; the piston rods can do to-and-fro movement up and down in the air compression tubes; and two air-compression energy conversion valves are arranged on the bottom walls of the two air compression tubes respectively. The shock absorber has the advantages that the shock absorber is small in volume, can save installation space, only uses air instead of oil, can save large quantities of hydraulic oil resources, and can reduce the environmental pollution of hydraulic oil during maintenance. The shock absorber adopts two-level independent air-compression shock absorption, and two levels of shock absorbers are good in respective independence and capable of mutual compensation, thereby overcoming the defect that the prior single-level air shock absorption or hydraulic shock absorption can only absorb shock but cannot reduce shock. The shock absorber is good in damping effect, ensures more stable running, and is suitable for various vehicles.

Description

【Technical field】 [0001] The invention relates to a shock absorber for a motor vehicle, in particular to an air compression vehicle shock absorber. 【Background technique】 [0002] Currently known motor vehicle shock absorbers, the more advanced hydraulic damping structure, it is through a wear-resistant and pressure-resistant rubber piston in the cylinder to move up and down, to promote the hydraulic oil in the cylinder through a pressure relief device, so that Hydraulic oil plays a vibration damping effect under a certain pressure. But the current hydraulic shock absorber mainly has the following defects: First, the single-stage shock absorption effect is not ideal. When the vehicle runs into a protruding high point, the shock absorber will be squeezed by the external impact force. When the shock absorber is at a low point, its own rebound force will increase, and the vehicle will be thrown to a higher high point, and a vehicle vibration will be unintentionally generated d...
