Abstract
A kind of automotive seat pneumatic spring, comprise valve, upper working of plastics, upper press ring, leather bag, lower pressure ring and lower working of plastics, it is characterized in that: described upper working of plastics integrated molding includes the screw for connecting product, for connecting the inlet hole of valve and the groove for waling leather bag, valve is fastened on the suction port on upper working of plastics by hexagon nut, the upper end of leather bag inwardly folds into banding and is sealed between working of plastics and upper press ring, the lower end banding of leather bag is sealed between lower working of plastics and lower pressure ring, upper working of plastics, leather bag and lower working of plastics three form a cavity, described upper press ring and lower pressure ring include outer shroud and inner ring.The utility model by adopting dicyclo pressure ring, make leather bag not easily from upper and lower cover plates come off and in joint not easy-rupturing, extend the working life of pneumatic spring, structure is simple, easy to assembly.
Description
Technical field
The utility model relates to a kind of pneumatic spring, particularly a kind of automotive seat pneumatic spring.
Background technique
Pneumatic spring is a kind of by the non-metal elastic element formed with the pressurized air pouring its inner chamber as capsule by cord, and its anti-vibration performance is mainly subject to the impact of stiffness characteristics, frequency characteristic and damping characteristic.Pneumatic spring is except being applied on vehicle, and be also applied in all kinds of locomotive seat damping, when vehicle receives the impact from uneven road surface, the air in pneumatic spring is compressed, and can effectively solve directly impacting the effect playing time delay and shock-absorbing.But the working life of pneumatic spring is shorter, affect the life-span of the mainly air bag of pneumatic spring physical life, several mode of failure below main appearance: 1, seal not labor and cause air bag to come off from upper and lower cover plates, 2, air bag is in the joint fatigue fracture etc. with upper and lower cover plates.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art part, the utility model provides longer automotive seat pneumatic spring in a kind of working life.
The technical solution adopted in the utility model is: a kind of automotive seat pneumatic spring, comprise valve, upper working of plastics, upper press ring, leather bag, lower pressure ring and lower working of plastics, it is characterized in that: described upper working of plastics integrated molding includes the screw for connecting product, for connecting the inlet hole of valve and the groove for waling leather bag, valve is fastened on the suction port on upper working of plastics by hexagon nut, the upper end of leather bag inwardly folds into banding and is sealed between working of plastics and upper press ring, the lower end banding of leather bag is sealed between lower working of plastics and lower pressure ring, upper working of plastics, leather bag and lower working of plastics three form a cavity, described upper press ring and lower pressure ring include outer shroud and inner ring.
Described inner ring sleeve is located in outer shroud, first with inner ring by leather bag banding on working of plastics, be located at outside inner ring with exterior ring cap again, outer shroud is strip, fasten with buckle after interior ring is tight, inner ring inwall is provided with some grooves, be equipped with the groove for entangling inner ring outward, inner ring and outer shroud are rubber ring, and elastic performance is good, inner ring width is 10cm, outer ring width is 15cm, and dicyclo uses the difficult drop-off that can leak gas by leather bag banding and not easily, good airproof performance, banding area ambassador leather bag joint not easy-rupturing when Long-Time Service, extends the physical life of pneumatic spring.
Described leather bag can adopt surplus leather bag or shortage of money leather bag according to different automobile types.
Described upper plastic part surface and lower plastic part surface are equipped with some stiffening ribs.
The beneficial effects of the utility model are: the utility model by adopting dicyclo pressure ring, make leather bag not easily from upper and lower cover plates come off and in joint not easy-rupturing, extend the working life of pneumatic spring, structure is simple, easy to assembly.
Accompanying drawing explanation
