Abstract
The invention discloses a clutch booster which comprises an air cylinder. A pushing rod and a dustproof cap are arranged on a front cover plate of the air cylinder; the front cover plate is provided with a ventilation groove pipe which is provided with external threads and is communicated with the outside. The clutch booster further comprises a ventilation pipe which is in thread fit with the ventilation groove pipe; an air filter device is arranged at the tail end of the ventilation pipe; a fixed end is arranged on an inlet of the air filter device; an opening expansion end is arranged on an air inlet of the fixed end. According to the clutch booster, the overall dustproof effect is improved, meanwhile, maintenance is convenient, and the service life is prolonged.
Description
Technical field
The present invention is mainly concerned with the clutch operation of vehicle transmission, especially relates to a kind of clutch booster.
Background technique
Along with the development of automotive engineering and the universal of use, the handling comfort of user to car load it is also proposed more and more higher requirement, and the handling comfort of clutch pedal is also affect user to one of index that car load driving is evaluated.Generally in the clutch specification that car load uses φ more than 300 time, just need between clutch master cylinder clutch booster is installed, use the compressed gas source of vehicle to provide power-assisted for clutch.
Heavy goods vehicles clutch booster is connected with the clutch housing of gearbox front portion usually, promotes clutch separation with high-pressure air.In the course of the work, the piston in cylinder comes and goes can produce respiration, produces the circulation of inner air and outer air whereby, the air required for suction, the turbidity thereof after exhalation internal work; On cylinder, be generally provided with ventilation barrel for this reason, meet piston and come and go gas required for activity.But, the clutch booster that we are commercially seen, the ventilation barrel on it is arranged on the dust cap of clutch booster front portion, and such arranges Shortcomings:
First, because the setting position of clutch booster is overhead lower, clutch booster is made to be in the higher environment of dust closeness, this can suck a large amount of dusts under the respiration of cylinder piston back and forth movement generation, and then formation cylinder interior accumulates a large amount of dusts, finally condense into block, impact uses, and block object is easy to scratch cylinder block and Sealing, causes clutch booster to lose efficacy.
The second, clear up even if follow-up, also there is trouble, not only need to dismantle dust cap, and piston comes and goes the ventilation barrel existence contraction back and forth to a certain degree made on dust cap for a long time, causes dust cap service life reduction, easily aging.
Addressing these problems is extremely urgent as from the foregoing!
In view of this, the present inventor has done deep research, and by feat of being engaged in experience and the practice of relevant industries for many years, design a kind of clutch booster, can deficiency of the prior art be solved, improve overall dust-proof effect, simultaneously easy to maintenance, increase the service life, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of clutch booster, improve overall dust-proof effect, simultaneously easy to maintenance, increase the service life.
Clutch booster, comprise cylinder, push rod and dust cap is provided with at the front shroud of cylinder, it is characterized in that: described front shroud is provided with the externally threaded ventilation barrel of the band communicated with the external world, also comprise the breathing pipe with ventilation barrel phase screw-thread fit, be provided with air filter at the end of breathing pipe, be provided with fixed end in the ingress of air filter, be provided with flared end at the suction port place of fixed end.
Do further preferably the present invention, described air filter comprises 2 three-way pipes be connected to each other, and is provided with air bag between the arm on described three-way pipe.
Do further preferably the present invention, the inlet end place of one of them three-way pipe described is provided with filter cotton, and the outlet side place of another three-way pipe is provided with filter screen.
Do further preferably the present invention, described flared end is horn mouth.
Do further preferably the present invention, described breathing pipe quality of rubber materials is made.
Do further preferably the present invention, the outside of described fixed end is provided with fixing frame.
Do further preferably the present invention, the outside of described fixed end is provided with magnetic part.
Compared with prior art comparatively, of the present inventionly to have the following advantages:
1, clutch booster of the present invention, the front shroud of cylinder arranges ventilation barrel, and installs air filter by breathing pipe, effectively reduces the Dust Capacity entered in cylinder, and the element of protection cylinder block and Sealing and inside, extends its working life.
2, the problem that otherwise address of the present invention dust cap working life is short, also to eliminate the trouble needing dismounting.
3, the present invention connects air filter can be arranged on a high position with breathing pipe, or the place that dust is relatively less and comparatively hidden, so can reduce the Dust Capacity entered in cylinder.
4, the air filter in the present invention separates with cylinder, independent mutually, and it breaks down or needs to be independent of each other when maintenance, replacing, easy to maintenance.
5, the installation of Center Vent tube of the present invention is very convenient, and also can pass through magnetic part by mounting bracket, its setting position is higher than cylinder, and the suction port on such breathing pipe is overhead high, is conducive to dust-proof effect.
6, the setting of air bag of the present invention effectively can solve in cylinder piston operation obstructed problem of ventilating, and when breathing pipe is long, the setting of air bag can increase the turnover of air quantity, has enough spaces, meets the piston movement of cylinder.
As from the foregoing, the present invention improves overall dust-proof effect, simultaneously easy to maintenance, increases the service life.
In order to explain technological scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
Accompanying drawing explanation
