Abstract
The invention discloses an air spring which comprises end caps, locking bolts and a rubber air spring, wherein the end caps comprise an upper end cap and a lower end cap; the upper end cap and the lower end cap are fixed to the upper end and the lower end of the rubber air spring through the locking bolts; aluminum alloy flanges are arranged outside the locking bolts; O-shaped sealing rings are arranged on the contact parts of the locking bolts and the rubber air spring; the rubber air spring adopts a three-layer structure which comprises an inner placing layer, a reinforcing layer and an outer medium-resistant layer from inside to outside in sequence. The air spring has the beneficial effects that the structure is compact and the service life is long; the O-shaped sealing rings are adopted, so that the sealing effect is excellent; the rubber air spring adopts the three-layer structure, that is, the inner placing layer is made of butyl rubber, so that the air impermeability is excellent; the reinforcing layer is made of glass fiber reinforcing rubber, so that the pressure resistance is good.
Description
Technical field
The present invention relates to a kind of pneumatic spring.
Background technique
The effect of pneumatic spring is to fill with pressurized air in telescopic seal container, utilizes the effectiveness that realizes spring of the elastic reaction of air.Be commonly called as air bag, balloon-type cylinder, leather bag cylinder etc.Thereby traditional gas spring is just by simply realizing the realization to buffering to pressurization in an air-tight movable sleeve pipe, and because the characteristic of air compressing, pneumatic spring under unexpected severe impact than being easier to occur touch end phenomenon, and pneumatic spring critical pressure is many greatly compared with spring, cannot adapt to some sensitivity and require high operating mode.So pneumatic spring is very strict to selecting of tightness and material, the tightness of a lot of pneumatic springs is poor in the market, therefore, needs a kind of new technological scheme to address the above problem.
Summary of the invention
The invention provides a kind of compact structure, pneumatic spring that tightness is good.
Beneficial effect of the present invention: a kind of pneumatic spring comprises end cap, lock bolt and rubber air spring, end cap comprises upper end cap and lower end cap, the two ends up and down of rubber air spring are fixed with upper end cap and lower end cap by lock bolt respectively, lock bolt outside is provided with aluminium alloy flange, lock bolt and rubber air bolt contacting point are provided with O-ring seals, rubber air spring is three-decker, is followed successively by from the inside to surface build-up layer, enhancement layer and media-resistant skin.
Above-mentioned rubber air spring be shaped as the shape for M, the centre of described rubber air spring is fixed with girdle ring.
Further, the material of build-up layer is butyl rubber, and the material of enhancement layer is fiberglass reinforced elastomers.
Beneficial effect of the present invention: pneumatic spring compact structure of the present invention, long service life; Adopt O-ring seals, good airproof performance; Rubber air spring is three-decker, and build-up layer is butyl rubber, and tightness is useful, and enhancement layer is fiberglass reinforced elastomers, and resistance to pressure is strong.
