Description
Technical field
The utility model relates to a kind of clutch booster, belongs to Clutch Technology field.
Background technique
Clutch booster is for the automobile of hydraulic control clutch device.When controlled clutch is separated or engage, assembly is used for helping to increase ouput force.The current clutch booster that adopts, process conditions are complicated mostly, and constructional device is complicated, therefore, need to be improved as required, to produce more qualified clutch booster.
Model utility content
The purpose of this utility model is to provide a kind of clutch booster, so that manufacture goes out the clutch booster that function simple in structure is more complete.
To achieve these goals, the technical solution of the utility model is as follows.
A clutch booster, comprises servo-cylinder, is provided with servo-cylinder piston in servo-cylinder, is provided with servo-cylinder piston apron and servo-cylinder piston supporting base between servo-cylinder piston and servo-cylinder; On servo-cylinder piston, be connected with servo-cylinder piston push rod, the servo-cylinder piston push rod the other end is connected with operating cylinder piston, on operating cylinder piston, is connected with return spring; Operating cylinder piston arranged outside has operating cylinder piston abrasion-proof cover.
Further, be provided with filler opening and suction port on the lid of operating cylinder outer surface of piston, suction port arranged outside has suction valve, and suction valve is connected with servo-cylinder outer wall; In suction valve, be provided with piston.
In this model utility device, clutch disengage process is: push down on the pedal, the high hydraulic brake fluid of clutch master cylinder, from filler opening input oil pocket, act on the left end of relay piston and operating cylinder piston, the oil cylinder piston that pushes the work forward on the one hand drives servo-cylinder piston push rod to push away to the right, promotes on the other hand relay piston and moves right, open air intake valve assembly, pressurized air flows into servo-cylinder piston left side air cavity through suction port.In gas power-assisted and hydraulic coupling, under effect, push rod moves right, thereby makes clutch compressing disc separated with driven disc.Clutch engagement process is: unclamp pedal, filler opening hydraulic pressure declines rapidly.Under the effect of clutch retraction springs, push rod moves right, air intake valve assembly and relay piston move right and close gas-entered passageway under the effect of air pressure and return spring simultaneously, it is spacing when air intake valve assembly is shifted to the right to fixed position, the certain distance but relay piston still can move to right, at this moment between valve assembly and relay piston, produced exhaust clearance, the pressure gas in cylinder left side enters atmosphere by relief opening, and push rod is got back to initial position.
The beneficial effect of this model utility is: this model utility device can carry out separation or engagement for clutch effectively, thereby has improved the working efficiency of clutch, has improved mode of operation and the working procedure of clutch.

Description of symbols in figure: 1, servo-cylinder piston supporting base; 2, servo-cylinder piston apron; 3, servo-cylinder piston; 4, servo-cylinder; 5, filler opening; 6, servo-cylinder piston push rod; 7, operating cylinder piston; 8, operating cylinder piston abrasion-proof cover; 9, suction port; 10, suction valve; 11, piston; 12, return spring.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, to better understand the utility model.
Clutch booster as shown in the figure, comprises servo-cylinder, is provided with servo-cylinder piston in servo-cylinder, is provided with servo-cylinder piston apron and servo-cylinder piston supporting base between servo-cylinder piston and servo-cylinder; On servo-cylinder piston, be connected with servo-cylinder piston push rod, the servo-cylinder piston push rod the other end is connected with operating cylinder piston, on operating cylinder piston, is connected with return spring; Operating cylinder piston arranged outside has operating cylinder piston abrasion-proof cover.
Further, be provided with filler opening and suction port on the lid of operating cylinder outer surface of piston, suction port arranged outside has suction valve, and suction valve is connected with servo-cylinder outer wall; In suction valve, be provided with piston.
In this model utility device, clutch disengage process is: push down on the pedal, the high hydraulic brake fluid of clutch master cylinder, from filler opening input oil pocket, act on the left end of relay piston and operating cylinder piston, the oil cylinder piston that pushes the work forward on the one hand drives servo-cylinder piston push rod to push away to the right, promotes on the other hand relay piston and moves right, open air intake valve assembly, pressurized air flows into servo-cylinder piston left side air cavity through suction port.In gas power-assisted and hydraulic coupling, under effect, push rod moves right, thereby makes clutch compressing disc separated with driven disc.Clutch engagement process is: unclamp pedal, filler opening hydraulic pressure declines rapidly.Under the effect of clutch retraction springs, push rod moves right, air intake valve assembly and relay piston move right and close gas-entered passageway under the effect of air pressure and return spring simultaneously, it is spacing when air intake valve assembly is shifted to the right to fixed position, the certain distance but relay piston still can move to right, at this moment between valve assembly and relay piston, produced exhaust clearance, the pressure gas in cylinder left side enters atmosphere by relief opening, and push rod is got back to initial position.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
