Abstract
The utility model relates to the field of piston sealing mechanisms, and provides a floating piston sealing mechanism of a single-cylinder shock absorber. The floating piston sealing mechanism of the single-cylinder shock absorber comprises a floating piston, an oil cylinder and an air cylinder. One end of the oil cylinder is connected with one end of the air cylinder. The floating piston is installed between the oil cylinder and the air cylinder. According to the floating piston sealing mechanism of the single-cylinder shock absorber, shock absorber oil and high-pressure nitrogen are separated, and oil products are effectively prevented from being emulsified and cavitated; the shock absorber oil is always in the pressed state due to the action of the high-pressure nitrogen, and therefore it is ensured that the shock absorber does not idle in any motion state, is started rapidly and reacts sensitively.
Description
Technical field
The utility model relates to a kind of floating piston sealing mechanism, relates in particular to a kind of floating piston sealing mechanism of single drum shock absorber.
Background technique
Concussion when the plug sealing mechanism of the vibration damper using at present, is mainly used to suppress rebound after spring shock-absorbing and from the impact on road surface.When through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and the piston sealing mechanism of vibration damper is used for suppressing this spring jump.The sealing of plug sealing mechanism is unstable, causes vibration damper too soft, and vehicle body will jump up and down, and vibration damper will bring too large resistance too firmly, hinders spring normal operation.In the retrofit process about suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight.
Model utility content
The technical problems to be solved in the utility model is, for the deficiencies in the prior art, and provides a kind of floating piston sealing mechanism of single drum shock absorber.
The utility model solves the technological scheme that its technical problem adopts: the floating piston sealing mechanism that a kind of single drum shock absorber is provided, comprise floating piston, oil cylinder and cylinder, one end of described oil cylinder is connected with one end of described cylinder, and described floating piston is installed between described oil cylinder and described cylinder.
The utility model further preferred version is: described floating piston is hollow circuit cylinder body structure, on its two wall, is provided with groove.
The utility model further preferred version is: O RunddichtringO is installed in described groove.
The utility model further preferred version is: the outer diameter of described floating piston is slightly less than the inner diameter of described oil cylinder.
The utility model further preferred version is: the outer diameter of described floating piston is slightly less than the inner diameter of described cylinder.
The utility model further preferred version is: the diameter of described oil cylinder is identical with the diameter of described cylinder.
Implement the technical solution of the utility model, there is following beneficial effect: the utility model is separated with high pressure nitrogen by shock absorber fluid, effectively prevent oil emulsion and cavitation, effect due to high pressure nitrogen, shock absorber fluid is all the time in pressured state, so guaranteed vibration damper under any motion state without idle running, play fast power, be quick on the draw.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the floating piston sealing mechanism of a kind of single drum shock absorber described in the utility model.
In figure: 1, floating piston 2, C RunddichtringO 3, oil cylinder 4, cylinder, 5, groove.
Embodiment
