Abstract
The utility model relates to a composite rubber air spring, which comprises an upper cover, an upper clamping ring, a lower clamping ring, a rubber bag, a piston, an upper O-shaped ring, a lower O-shaped ring and a quick connector, wherein the quick connector is fully surrounded by the piston, and an outward extending part of the piston forms a supporting platform; a lower seam allowance of the rubber bag is clamped on the piston, and the lower seam allowance is tightly buckled on the rubber bag through the lower clamping ring; and an upper seam allowance is tightly buckled on the upper cover through the lower clamping ring. Based on the traditional buckling process, a structure of a buckling mold is adjusted, and the buckling contact area is appropriately reduced, so that every mold block can be mutually buckled in buckling, the buckling roundness is ensured, and the air tightness of products is greatly improved. The original quick connector is arranged on the piston and then is exposed to the outside, so that the quick connector is easily damaged due to collision when the quick connector is in transportation and in use, thereby leading to the failure of a product assembly. Therefore, a local structure of the piston is optimized, and a threaded joint of the piston is sunk, so that the quick connector is fully surrounded by the piston, the quick connector is prevented from being damaged without affecting the installation, and simultaneously the service life of the products is improved.
Description
Technical field
The utility model relates to a kind of shock-absorption device that is used on truck, commercial car, the heavy truck, specifically, relates to a kind of combined type rubber air spring.
Background technique
Along with the development of China Higher level highway, the increase of transport volume and the raising of living standards of the people, control stability, smoothness and the Security of automobile are had higher requirement.Hang with conventional steel and to compare, air suspension has a lot of advantages, and the most important is exactly that the elastic stiffness of spring can be regulated as required automatically.The combined air air spring can be used on the air suspension of the operator cabin that heavily blocks vehicle and MPV, SUV, promptly can save installing space after combining, and the vibration damper function is not fully exerted, and can also protects vibration damper.American-European 80% passenger vehicle, commercial car and heavy truck all are equipped with AIRMATIC Dual Control at present.Domestic starting late has approximately at present on 30% the heavily card combined type air suspension system is housed.There is certain defective in the tightness of existing combined air air spring, and quick inserting joint to be installed on the piston back exposed outside, the damage of colliding with easily in transportation and in using causes the product assembly failure.
The model utility content
The poor air-tightness that the utility model exists at existing combined air air spring, product short problem in working life have proposed that a kind of tightness is good, simple and reasonable, the novel combined rubber air spring of long service life.
The technical solution of the utility model is: a kind of combined type rubber air spring, comprise loam cake, snap ring, capsule, piston, O type circle and quick inserting joint up and down up and down, described quick inserting joint is surrounded in the piston fully, and the described piston outside extends outward a part and forms a support platform; The rim of the mouth is stuck on the piston under the described capsule, and by following snap ring and the tight latch closure of capsule, snap ring and the tight latch closure of loam cake are down passed through in last rim of the mouth.
Preferably: described loam cake central authorities are provided with the O RunddichtringO.
Preferably: described piston bottom is provided with down the O RunddichtringO.
The beneficial effects of the utility model are: the utility model enlarges the loam cake root opening by adjusting the thread groove size, makes capsule that enough packing spaces be arranged when withholding, and satisfies the tightness requirement.Withhold on the technology basis existing, adjusted and withheld mould structure, suitably reduce to withhold area of contact, make when withholding to have guaranteed to withhold circularity by each lobe mould piece latch closure mutually, improve products air tightness greatly.Expose outside after original quick inserting joint is installed on the piston, the damage of colliding with easily in transportation and in using causes the product assembly failure.For these partial structurtes to piston are optimized, the piston thread joint is sunk, quick inserting joint is fully enclosed in the piston, under the situation that does not influence installation, avoided quick inserting joint to be damaged, improved the working life of product simultaneously.
Description of drawings
Accompanying drawing 1 is the cross-sectional view of the utility model specific embodiment.
Embodiment
Embodiment of the present utility model is as follows: a kind of combined type rubber air spring, comprise loam cake 1, snap ring 2,4, capsule 3, piston 5, O type circle 8,7 and quick inserting joint 6 up and down up and down, described quick inserting joint 6 is surrounded in the piston 5 fully, and described piston 5 outsides extend outward a part and form a support platform; 3 times rims of the mouth of described capsule are stuck on the piston 5, and by following snap ring 4 and capsule 3 tight latch closures, last rim of the mouth is by last snap ring 2 and loam cake 1 tight latch closure; Loam cake 1 central authorities are provided with O RunddichtringO 8, and the piston bottom is provided with down O RunddichtringO 7.
During work, the combined air air spring is fixed on the capsule upper and lower end on loam cake and the piston respectively by upper and lower snap ring, and fills exhaust by quick inserting joint, at last by the sealing of O type circle realization with vibration damper.
Claims (3)
1. combined type rubber air spring, comprise loam cake (1), snap ring (2), (4), capsule (3), piston (5), O type circle (8), (7) and quick inserting joint (6) up and down up and down, it is characterized in that: described quick inserting joint (6) is surrounded in the piston (5) fully, and described piston (5) outside extends outward a part and forms a support platform; Described capsule (3) is stuck on the piston in the rim of the mouth down, and by the tight latch closure of following snap ring (4) and capsule (3), last rim of the mouth is by the tight latch closure of last snap ring (2) and loam cake (1).
2. combined type rubber air spring as claimed in claim 1 is characterized in that: described loam cake (1) central authorities are provided with O RunddichtringO (8).
