Description
Technical field
Present invention relates generally to the clutch operating device of vehicle transmission, especially relate to a kind of dust protected clutch and help
Power device.
Background technology
Generally anterior with the gearbox clutch housing of heavy goods vehicles clutch booster is connected, and promotes clutch with pressure-air
Device separates.In the course of the work, the piston in cylinder comes and goes and can produce respiration, produces the circulation of inner air and outer air whereby, inhales
Air required for entering, the turbidity thereof after exhalation internal work；For this, ventilation barrel is typically provided on cylinder, to meet work
Plug comes and goes the gas required for activity.But, our commercially seen clutch boosters, ventilation barrel thereon sets
Put on the anterior dust cap of clutch booster, such setting Shortcomings：
First, due to the set location of clutch booster relatively low from the ground so that clutch booster to be in dust close
In the higher environment of intensity, this, under the respiration that cylinder piston back and forth movement produces, can suck substantial amounts of dust, and then shape
Cylinder interior is become to accumulate substantial amounts of dust, final condensation is blocking, and impact uses, block object is easy to scratch cylinder block and sealing
Part, leads to clutch booster to lose efficacy.
Second, even if subsequently being cleared up, there is also trouble, not only needing to dismantle dust cap, and long piston
Come and go make the ventilation barrel on dust cap exist a certain degree of shrink back and forth, lead to dust cap service life reduction, easily aging.
In addition, the piston head being used in the market in booster, with the prolongation of working time, cause the mill of sealing ring
Damage, seal clearance cannot compensate, sealing effectiveness declines, and causes gas leakage, so that clutch booster was lost efficacy.
Content of the invention
It is an object of the invention to provide a kind of dust protected clutch booster, improve overall dust-proof effect, piston
Sealing property and service life, simultaneously easy to maintenance.
Dust protected clutch booster, has the pneumatic cylinder connecting along same axis and hydraulic cylinder, and described piston is placed in gas
In cylinder pressure, be provided with the push rod being connected with piston in the front shroud of pneumatic cylinder it is characterised in that：Described front shroud is provided with first and leads to
Air drain pipe and the second ventilation barrel, the port of described first ventilation barrel is provided with the first removable cover by spring part, the
The port inner wall of one ventilation barrel is provided with male member, limits removable cover inwardly movable；The port mistake of described second ventilation barrel
Spring part is provided with the second removable cover, is provided with male member in the port of the second ventilation barrel, limits removable cover outwards movable；Institute
State the second ventilation barrel and connect band tubing, be provided with fixing end in the inlet end of band tubing, be provided with air mistake at fixing end
Filter device.
Further, described air filter is a breather plug.
Further, described air filter includes the circular body with outlet side, is formed multiple in circular body
Aperture, inside is provided with filter cotton, is provided with screen pack on outlet side.
Further, described piston includes piston rod, forms piston head in the end of piston rod, is formed in the outer wall of piston head
Article two, annular groove, is provided with seal in annular groove.
Further, described seal is y-type seal ring, and when described sealing ring is placed in annular groove, lip is outside.
Further, the outboard end in annular groove forms scrobicular ring, is provided with elliptical seal ring in scrobicular ring.
Further, the outside of described fixing end is provided with fixed mount.
Further, the outside of described fixing end is provided with magnetic part.
Compared with prior art, it is an advantage of the current invention that：
1st, the present invention arranges the first ventilation barrel and the second ventilation barrel, the wherein first air channel on the front shroud of cylinder
Pipe is used for giving vent to anger, and the second air channel pipe is used for both air inlets separately, improves efficiency, is effectively lowered into the dust in cylinder
Amount, and be conducive to improving the internal dust of discharge, the element of protection cylinder block and seal and inside.
2nd, otherwise address of the present invention dust cap service life short problem, also eliminating needs the trouble of dismounting.
3rd, the air filter in the present invention, can be connected by fixing end and be placed on a high position, or dust is relatively
Less and more hidden place, so the Dust Capacity being lowered in cylinder.
4th, the air filter in the present invention and cylinder separate, independent mutually, and it breaks down or needs maintenance, changes
When be independent of each other, easy to maintenance.
5th, the fixing end in the present invention can be provided with by outside support or magnetic part, can arbitrarily be fixed on required
The position wanted, very convenient.
6th, the outer wall of inventive piston head forms two annular grooves, is provided with seal, using process in annular groove
Middle seal is y-type seal ring, and when described sealing ring is placed in annular groove, lip is outside, shape so and cylinder inner wall between
Become good sealing effectiveness and performance；For the skew producing in the abrasion of compensation sealing part and motion process, in annular groove
Outboard end form scrobicular ring, be provided with elliptical seal ring in scrobicular ring, thus the piston in the present invention have good servo-actuated close
Sealing property.
From the foregoing, it will be observed that the present invention improves overall dust-proof effect, simultaneously easy to maintenance, increase the service life.
In order to technical scheme is explained further, the present invention is explained in detail below by specific embodiment
State.
