Air bag type shock absorber for two-wheeled or three-wheeled vehicle

Abstract

An embodiment of the invention discloses an air bag type shock absorber for a two-wheeled or three-wheeled vehicle. The air bag type shock absorber comprises a hydraulic shock absorber assembly, an air spring assembly, an anti-collision buffering mechanism and a pressure monitoring mechanism. The air spring assembly is arranged on the hydraulic shock absorber assembly in a sleeving manner. The anti-collision buffering mechanism is arranged on the hydraulic shock absorber assembly and arranged in an inner cavity of the air spring assembly. The pressure monitoring mechanism is arranged outside the air spring assembly. The pressure monitoring mechanism comprises a communicating hole and a pressure gauge. The communicating hole is formed in an air spring piston. The pressure gauge is arranged outside the communicating hole. The interior of the communicating hole communicates with the inner cavity of the air spring. The anti-collision buffering mechanism comprises a buffering block and a lower supporting gasket. The lower supporting gasket is arranged at an end of a sleeve. The buffering block is fixedly arranged at an end of a hydraulic telescopic rod. The buffering block and the lower supporting gasket are oppositely arranged. The air bag type shock absorber is simple in structural design, good in buffering effect, accurate in pressure monitoring and good in anti-collision effect.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobile shock absorbers, in particular to an airbag type shock absorber for a two-wheel or tricycle. Background technique [0002] In order to quickly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the car, the car suspension system is generally equipped with a shock absorber. With the development of the shock absorber, the car shock absorber is widely used Double-acting cylinder shock absorbers, airbag shock absorbers, etc. [0003] Among them, the airbag shock absorber is an inflatable shock absorber, which uses air resistance to slow down the vibration of the frame and achieve the purpose of driving comfort. Existing airbag shock absorbers have been used in many high-end models, improving user experience, especially with the development of shock absorbers, the combination of air springs and barrel shock absorbers has appeared in t...

AI Technical Summary

Problems solved by technology

Existing airbag shock absorbers have been used in many high-end models, improving user experience, especially with the development of shock absorbers, the combination of air springs and barrel shock absorbers has appeared in the prior art Shock-absorbing buffer structure, its application effect combines the advantages of airbag air spring and cylinder shock absorber, but in the process of use, because the gas in the airbag will gradually seep out from the edge, the air pressure will gradually decrease, weakening its Cushioning effect, at the same time, there is no air pressure monitoring function, so it is difficult to replenish air in time; at the same time, when the cylinder shock absorber is in use, it is easy to cause damage due to collision between the sleeve and the air spring
