Abstract
The invention relates to a clutch control mechanism for automobile transmission, in particularly to a clutch assisting device. The clutch assisting device comprises an air cylinder, a push rod and a dustproof cover; one end of the dustproof cover is in sealing connection with the push rod; the other end of the dustproof cover is in sealing connection with a front cover plate of the air cylinder; the dustproof cover is in a full-sealing structure; the front cover plate of the air cylinder is provided with a ventilation pipe; the ventilation pipe is in a reversed L shape; one end of the ventilation pipe is communicated with the air cylinder; the other end of the ventilation pipe is communicated with the exterior; a connecting end of the ventilation pipe and the air cylinder is higher than that of the ventilation pipe and the exterior; an air filtration device is arranged inside the ventilation pipe. According to the technical scheme of the clutch assisting device, the structure is simple, the dustproof effect is good, the service life of the clutch is prolonged, and convenience is brought to a user.
Description
Technical field
The present invention relates to the clutch operation of vehicle transmission, be specifically related to a kind of clutch booster device.
Background technique
Heavy goods vehicles clutch servo device 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.The vent of existing clutch servo device is on the dust-proof cover of clutch servo device front portion, and the usual road clearance of the layout of clutch servo device is lower, clutch servo device is made to be in the higher environment of dust closeness, under the respiration that cylinder piston back and forth movement produces, because vent directly communicates with air, so the dust in air can enter cylinder block inside along with respiratory air flow from vent.Along with the prolongation of service time, the dust entering cylinder block can be cumulative, and get off for a long time to have part dust produce chemical change be frozen into lump, in the working procedure of clutch servo device, easily pull cylinder block and Sealing, cause clutch servo device to lose efficacy.
Summary of the invention
The object of the invention is to: provide that a kind of structure is simple, good dustproof effect, and the clutch booster device in clutch working life can be extended.
To achieve these goals, the invention provides a kind of clutch booster device, comprise cylinder, push rod and dust-proof cover, described dust-proof cover one end is connected with described push rod seal, the described dust-proof cover the other end and described air cylinder front cover plate are tightly connected, described dust-proof cover is all-sealed structure, described air cylinder front cover plate offers breathing pipe, described breathing pipe is inverted L-shaped, described breathing pipe one end is communicated with cylinder, the described breathing pipe the other end communicates with the external world, described breathing pipe and cylinder connecting end position are higher than described breathing pipe and extraneous connecting end, air filter is provided with in described breathing pipe.
The clutch booster device tool of technical solution of the present invention is adopted to have the following advantages: because dust-proof cover adopts full-closed structure, the dust avoided in air directly enters cylinder by dust-proof cover, avoid the dust of accumulation to the destruction to cylinder block and Sealing, owing to offering the breathing pipe of inverted L-shaped on air cylinder front cover plate, and be provided with filtrating equipment in breathing pipe, when air enters cylinder by piston movement, first through filtrating equipment, reduce the dust content in air, dust is accumulated on filtrating equipment, be piled into solid particle for a long time, in automobilism vibration processes, particle drops out breathing pipe due to self gravitation effect, avoid dust to enter cylinder interior and damage cylinder block and Sealing, bring convenience to user.
Preferably, consider the restriction of breather pipe structure, and can play good dust removal by filtration effect, described air filter is the netted fleece of multilayer.
Preferably, consider that filtrating equipment can play better filtration in breathing pipe, and the dust granules after accumulation can be discharged automatically along breathing pipe, described air filter is arranged on described breathing pipe bending part.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention clutch booster device schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the invention provides a kind of clutch booster device, comprise cylinder 1, push rod 2 and dust-proof cover 3, dust-proof cover 3 adopts corrugated connecting circular tube, one end and the push rod 2 of dust-proof cover 3 are sealedly and fixedly connected, dust-proof cover 3 the other end and air cylinder front cover plate 4 are sealedly and fixedly connected, due to stressed less herein, sealer can be adopted to connect to ensure that dust-proof cover 3 is for all-sealed structure, air cylinder front cover plate 4 top offers breathing pipe 5, breathing pipe 5 is inverted L-shaped, breathing pipe 5 one end is communicated with cylinder 1, breathing pipe 5 the other end communicates with the external world and downward, breathing pipe 5 and cylinder 1 connecting end position are higher than breathing pipe 5 and extraneous connecting end, air filter is provided with in breathing pipe 5, consider the restriction of breathing pipe 5 structure, and can play good dust removal by filtration effect, air filter is the netted fleece 6 of multilayer, consider that the netted fleece of multilayer 6 can play better filtration in breathing pipe 5, and the dust granules after accumulation can be discharged automatically along breathing pipe 5 downwards, described air filter 6 is arranged on described breathing pipe 5 bending part.
When the piston of push rod 2 with dynamic air cylinder 1 moves reciprocatingly time, the cylinder wall inner chamber air pressure of push rod 2 side also changes, now air can be sucked by breathing pipe 5 or be discharged, to keep air pressure balance, air is filtered through dust during multilayer netted fleece 6, when air passes multilayer netted fleece 6, vibrations in conjunction with vehicle are saved bit by bit the dust even lumpd on the netted fleece 6 of multilayer and breathing pipe 5 and can be blown, thus the cylinder wall of guarantee push rod 2 side does not save bit by bit dust, avoid damage.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
Claims (3)
1. clutch booster device, comprise cylinder, push rod and dust-proof cover, described dust-proof cover one end is connected with described push rod seal, the described dust-proof cover the other end and described air cylinder front cover plate are tightly connected, it is characterized in that: described dust-proof cover is all-sealed structure, described air cylinder front cover plate offers breathing pipe, described breathing pipe is inverted L-shaped, described breathing pipe one end is communicated with cylinder, the described breathing pipe the other end communicates with the external world, described breathing pipe and cylinder connecting end position, higher than described breathing pipe and extraneous connecting end, are provided with air filter in described breathing pipe.
