Description
Technical field
The present invention relates to a kind of spring, particularly relate to a kind of hydro-pneumatic spring.
Background technique
Gas spring is divided into pneumatic spring and hydro-pneumatic spring two kinds, and structure, the principle of pneumatic spring are all very simple, and comparatively greatly, existing hydro-pneumatic spring complex structure, safeguards inconvenient for using effect and hydro-pneumatic spring difference.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides a kind of hydro-pneumatic spring.
In order to overcome the defect existed in background technique, the technical solution adopted for the present invention to solve the technical problems is: this hydro-pneumatic spring comprises piston, group star valve, spherical chamber, air chamber, barrier film and clutch release slave cylinder, the upper end of described clutch release slave cylinder is provided with spherical chamber, piston is provided with in described clutch release slave cylinder, the centre of described spherical chamber is provided with barrier film, the upper end of described barrier film is air chamber, is provided with organizes star valve bottom spherical chamber with clutch release slave cylinder joint.
The invention has the beneficial effects as follows: the structure of this hydro-pneumatic spring is simple, easy to maintenance, has the characteristic of variation rigidity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Wherein: 1, piston, 2, group star valve, 3, spherical chamber, 4, air chamber, 5, barrier film, 6, clutch release slave cylinder.
Embodiment
Fig. 1 is structural representation of the present invention, figure comprises piston 1, group star valve 2, spherical chamber 3, air chamber 4, barrier film 5 and clutch release slave cylinder 6, the upper end of clutch release slave cylinder 6 is provided with spherical chamber 3, piston 1 is provided with in described clutch release slave cylinder 6, the centre of described spherical chamber 3 is provided with barrier film 5, the upper end of described barrier film 5 is air chamber 4, is provided with organizes star valve 2 bottom spherical chamber 3 with clutch release slave cylinder 6 joint.
When load increase and vehicle frame and vehicle bridge close to each other time, piston moves, clutch release slave cylinder internal volume is reduced, oil pressure raises, and fluid backs down orifice valve and enters spherical chamber, promotes barrier film and moves as air chamber direction, gas chamber volume is reduced, and nitrogen pressure raises, and the rigidity of hydro-pneumatic spring increases.When load decreases, move to direction, grease chamber at the effect lower diaphragm plate of high pressure nitrogen, indoor fluid flows back to clutch release slave cylinder through orifice valve, and promote piston and move down, at this moment gas chamber volume increases, and nitrogen pressure declines, and spring rate reduces.
The structure of this hydro-pneumatic spring is simple, easy to maintenance, has the characteristic of variation rigidity.
