Abstract
The utility model relates to the technical field of configuration of automobiles, particularly relates to a kind of two-stage type hydro pneumatic suspension device.This two-stage type hydro pneumatic suspension device comprises piston, first order pressure cylinder, diaphragm of rubber one, diaphragm of rubber two and second stage pressure cylinder, described piston is placed in pipeline, first order pressure cylinder and second stage pressure cylinder is provided with in the both sides of pipeline, be provided with diaphragm of rubber one in described first order pressure cylinder, the bottom of described second stage pressure cylinder is provided with diaphragm of rubber two.The structure of this two-stage type hydro pneumatic suspension device is simple, even if automobile travels on uneven road surface, by the effect of chamber internal gas pressure, still can travel by held stationary.
Description
Technical field
The utility model relates to a kind of hydro pneumatic suspension, particularly relates to a kind of two-stage type hydro pneumatic suspension device.
Background technology
Vehicle suspension system is the key factor affecting automotive performance, and good suspension design can isolate the vibration on road surface effectively, suppresses the resonance of wheel and vehicle body, provides good travelling comfort, riding comfort; Good road-holding property and driving safety can also be provided simultaneously, improve the average speed of operation of automobile.The passive suspension system of the mechanical type that general automobile adopts mostly is made up of bumper and coil spring or steel spring.Spring stiffness is a definite value normally, in order to the stationarity ensureing that vehicle travels on different road surface, needs the rigidity of suspension softer, thus needs larger suspension space.The size of jolting and vibrating of car body depends on the structure of suspension system and the quality of its performance.
Summary of the invention
The technical problems to be solved in the utility model is: the size of jolting and vibrating of car body depends on the structure of suspension system and the quality of its performance, provides a kind of two-stage type hydro pneumatic suspension device.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical matters adopts: this two-stage type hydro pneumatic suspension device comprises piston, first order pressure cylinder, diaphragm of rubber one, diaphragm of rubber two and second stage pressure cylinder, described piston is placed in pipeline, first order pressure cylinder and second stage pressure cylinder is provided with in the both sides of pipeline, be provided with diaphragm of rubber one in described first order pressure cylinder, the bottom of described second stage pressure cylinder is provided with diaphragm of rubber two.
According to another embodiment of the invention, described first order pressure cylinder and the rounded shape of second stage pressure cylinder is comprised further.
The beneficial effects of the utility model are: the structure of this two-stage type hydro pneumatic suspension device is simple, even if automobile travels on uneven road surface, by the effect of chamber internal gas pressure, still can travel by held stationary.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, piston, 2, first order pressure cylinder, 3, diaphragm of rubber one, 4, diaphragm of rubber two, 5, second stage pressure cylinder.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, comprise piston 1, first order pressure cylinder 2, diaphragm of rubber 1, diaphragm of rubber 24 and second stage pressure cylinder 5, described piston 1 is placed in pipeline, first order pressure cylinder 2 and second stage pressure cylinder 5 is provided with in the both sides of pipeline, be provided with diaphragm of rubber 1 in described first order pressure cylinder 2, the bottom of described second stage pressure cylinder 5 is provided with diaphragm of rubber 24.
Integrally-built feature has two air chambers arranged side by side at upper piston area, but its operation pressure is different, the nitrogen that air pressure is close with normal single air chamber hydro pneumatic suspension is filled with in A air chamber, the nitrogen higher than main gas tank air pressure is filled with in B air chamber, gas and fluid all separate with diaphragm of rubber by two air chambers, the effect of two air chambers just as spring main in steel spring the same with the effect of auxiliary spring.
Such a construction ensures automobile zero load and have roughly equal eigentone with at full load suspension, thus improve the ride comfort of running car.
