Description
Technical field
The utility model is mainly concerned with the clutch operation of vehicle transmission, especially relates to a kind of dust protected clutch booster.
Background technique
Heavy goods vehicles clutch booster is connected with the clutch housing of gearbox front portion conventionally, with high-pressure air, promotes clutch separation.In the course of the work, the piston in cylinder comes and goes and can produce respiration, and the circulation that produces whereby inner air and outer air, sucks needed air, the muddy gas after exhalation internal work; On cylinder, be generally provided with ventilation barrel for this reason, meet piston and come and go movable needed gas.But, the clutch booster that we are seen on market, the ventilation barrel on it is arranged on the dust cap of clutch booster front portion, such Shortcomings that arranges:
First, because the setting position of clutch booster is overhead lower, make clutch booster in the higher environment of dust closeness, under this respiration producing at cylinder piston back and forth movement, can suck a large amount of dusts, and then formation cylinder interior accumulates a large amount of dusts, finally condense into piece, impact is used, and block object is easy to scratch cylinder block and Sealing, causes clutch booster to lose efficacy.
The second, even follow-up, clear up, also there is trouble, not only need to dismantle dust cap, and piston comes and goes the ventilation barrel making on dust cap and has contraction back and forth to a certain degree for a long time, causes the dust cap life-span to be reduced, easily aging.
In addition, in the market for the piston head in booster, along with the prolongation of operating time, cause the wearing and tearing of seal ring, seal clearance can not get compensation, and sealing effect declines, and causes gas leakage, and clutch booster was lost efficacy.
Model utility content
The purpose of this utility model is to provide a kind of dust protected clutch booster, improves sealability and the working life of whole dust-proof effect, piston, simultaneously easy to maintenance.
Dust protected clutch booster, there is the pneumatic cylinder and the oil hydraulic cylinder that along same axis, connect, described piston is placed in pneumatic cylinder, front shroud at pneumatic cylinder is provided with the push rod being connected with piston, it is characterized in that: described front shroud is provided with the first ventilation barrel and the second ventilation barrel, the port of described the first ventilation barrel is provided with the first removable cover by spring part, at the port inner wall of the first ventilation barrel, is provided with male member, and restraint cover plate is inwardly movable; The port of described the second ventilation barrel is crossed spring part and is provided with the second removable cover, in the port of the second ventilation barrel, is provided with male member, and restraint cover plate is outwards movable; Described the second ventilation barrel connects rubber hose, at the inlet end of rubber hose, is provided with fixed end, and at fixed end, place is provided with air filter.
Further, described air filter is a breather plug.
Further, described air filter comprises the circular body with outlet side, forms a plurality of apertures in circular body, and inside is provided with filter cotton, is provided with filter screen on outlet side.
Further, described piston comprises piston rod, in the end of piston rod, forms piston head, and two annular grooves of outer wall formation at piston head are provided with Sealing in annular groove.
Further, described Sealing is y-type seal ring, and when described seal ring is placed in annular groove, lip is outside.
Further, the outboard end formation scrobicular ring at annular groove is provided with elliptical seal ring in scrobicular ring.
Further, the outside of described fixed end is provided with fixing frame.
Further, the outside of described fixed end is provided with magnetic part.
Compared with prior art, the utility model has the advantage of:
1, the utility model arranges the first ventilation barrel and the second ventilation barrel on the front shroud of cylinder; wherein the first vent slot pipe is used for giving vent to anger; and the second vent slot pipe is used for air inlet, both separate; raise the efficiency; effectively reduce and enter the Dust Capacity in cylinder; and be conducive to improve the inner dust of discharge, protect cylinder block and Sealing and inner element.
2, the utility model otherwise address dust cap short problem in working life, also removed the trouble that needs dismounting from.
3, the air filter in the utility model, can be connected and be placed on a high position by fixed end, or the relatively less and comparatively hidden place of dust, so can reduce the Dust Capacity entering in cylinder.
4, the air filter in the utility model separates with cylinder, independent mutually, and it is independent of each other when breaking down or needing maintenance, replacing, easy to maintenance.
5, the fixed end in the utility model can be provided with by outside support or magnetic part, can arbitrarily be fixed on needed position, very convenient.
6, the outer wall of the utility model piston head forms two annular grooves, in annular groove, be provided with Sealing, in using process, Sealing is y-type seal ring, and when described seal ring is placed in annular groove, lip is outside, like this and between cylinder inner wall, form good sealing effect and performance; For the skew producing in the wearing and tearing of compensation sealing part and movement process, at the outboard end of annular groove, form scrobicular ring, in scrobicular ring, be provided with elliptical seal ring, so the piston in the utility model has good Follow-up seal performance.
As from the foregoing, the utility model improves whole dust-proof effect, simultaneously easy to maintenance, increases the service life.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
