Abstract
The utility model relates to a fuel feeding clutch power steering pump which is characterized in that: a cylinder piston is connected with a cylinder ejector rob, a fluid cylinder is internally provided with a piston which is matched with the cylinder ejector rob, the fluid cylinder is internally provided with an active cabin and a passive cabin, one end of the piston is provided with a valve, and the active cabin is connected with a gas control valve which is connected with the cylinder piston by an air inlet pipe. When in use, hydraulic oil of a clutch master cylinder is transported to the active cabin of the fluid cylinder through an oil inlet hole and is input to the passive cabin through a piston oil conduit at the same time; when the pressure of the active cabin rises, the cylinder piston motions to drive the piston in the fluid cylinder to move; when a valve on the piston closes the piston oil conduit, the passive cabin forms closed environment, and the piston continues to motion to drive the hydraulic oil in the passive cabin to lead the hydraulic oil to be supplied for a direct automobile clutch wheel cylinder through the oil outlet hole and cause the clutch to be separated, thereby ensuring the foot power of a clutch pedal to be lightened, the operation to be comfortable and the clutch to be steady.
Description
Technical field:
The utility model relates to the technical field of clutch power-assisted pump, specifically a kind of oil feeding type clutch power-assisted pump.
Background technique:
At present existing clutch control and clutch slave cylinder have following several form:
1, leverage formula: this is the most original a kind of, the shortcoming of this structure is that friction point is many, driver's labor intensity is big, influence because of the multiple spot gap, the departure clatter, can cause automobile, tractor clutch to separate thoroughly and phenomenons such as the difficulty of putting into gear, the sound of putting into gear cause the accelerated wear test as friction plate, transmission gear, synchronizer and other transmission paries, cause automobile to travel when serious.
2, lever and hydraulic pressure combined type: this mechanism is that to have increased hydraulic mechanism in the leverage formula be clutch master cylinder and wheel cylinder improving usability, but still it is big and along with the degree of wear increases and the bigger fatal shortcoming of error to eliminate error.
3, for the labor intensity that alleviates the driver derives servomechanisms such as air pressure, hydraulic pressure, vacuum, but these mechanisms still can't overcome the shortcoming that leverage formula and lever and hydraulic pressure combined type exist.
These clutch power-assisted pump outputs is mechanical force simultaneously, can't supply with clutch slave cylinder with hydraulic oil power.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved oil feeding type clutch power-assisted pump, and it can overcome in the prior art automobile clutch boost pump can't output oil pressure power, clutch process some shortcomings not too stably.
To achieve these goals, the technical solution of the utility model is: a kind of oil feeding type clutch power-assisted pump, it mainly comprises cylinder, cylinder piston and the oil hydraulic cylinder that links to each other with cylinder, it is characterized in that: cylinder piston links to each other with an ejecting rod of cylinder, be provided with the piston that matches with ejecting rod of cylinder in the oil hydraulic cylinder, oil hydraulic cylinder is provided with initiatively storehouse and passive storehouse, and an end of piston is provided with valve, initiatively the storehouse links to each other with an air control valve, links to each other by suction tude between air control valve and the cylinder piston.
When the hydraulic oil of clutch master cylinder of the present utility model is transported to oil hydraulic cylinder active storehouse by filler opening during use, also import passive storehouse by the piston oil duct on the piston, initiatively the pressure in storehouse raises, air pressure is also along with the unlatching of air control valve enters cylinder simultaneously, the amplitude of air inflow increases along with the lengthening of piston stroke, the cylinder piston motion also promotes the interior piston motion of oil hydraulic cylinder, valve closing piston oil duct on the piston, make passive storehouse form the environment of sealing, piston continuation motion promotes the hydraulic oil in the passive storehouse again, make hydraulic oil supply with direct-type automobile clutch wheel cylinder and make clutch separation by oil outlet, the legpower of clutch pedal is alleviated, operate comfortablely, clutch is steady, for direct-type automobile clutch wheel cylinder provides necessary boosting mechanism to full-sized car.
Description of drawings:
Fig. 1 is the utility model one embodiment's a structural representation
Fig. 2 is the another embodiment's of the utility model a structural representation
Fig. 3 is another embodiment's of the utility model a structural representation
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises cylinder 7, cylinder piston 18 and the oil hydraulic cylinder 3 that links to each other with cylinder, link to each other by retaining screw 17 between cylinder and the oil hydraulic cylinder, its difference with the prior art is: cylinder piston links to each other with an ejecting rod of cylinder 10, be provided with the piston 5 that matches with ejecting rod of cylinder in the oil hydraulic cylinder, piston is divided into initiatively storehouse 9 and passive storehouse 13 with oil hydraulic cylinder, one end of piston is provided with valve 4, and initiatively the storehouse links to each other with an air control valve 19, links to each other by suction tude 8 between air control valve and the cylinder piston.One end of oil hydraulic cylinder is a filler opening 6, and the other end is an oil outlet 1, is provided with the piston reset spring 16 that matches with piston in the passive storehouse, is provided with valve control bolt 2 in the oil hydraulic cylinder, and an end of valve is provided with valve spring 15.Be provided with piston oil duct 12 in the piston, an end of piston oil duct links to each other with passive storehouse, and the other end of piston oil duct links to each other with the active storehouse, is provided with oil sealing 11 between piston and the oil hydraulic cylinder.Be provided with the cylinder piston Returnning spring 21 that matches with cylinder piston in the cylinder.Valve control bolt is arranged in the active storehouse, contacts with the middle-end of piston; In another kind was implemented, then valve control bolt was arranged in the passive storehouse, links to each other with valve.
In force, when the driver steps clutch pedal, the brake oil of clutch master cylinder flows into the active storehouse 9 of oil hydraulic cylinder through oil hydraulic cylinder (boost pump) filler opening 6 by oil pipe, initiatively the pressure in storehouse rising while brake oil is injected passive storehouse 13 through the valve 4 of piston and unlatching, pressure is opened air control valve 19 simultaneously, there is the air of pressure to inject in the cylinder 7 by suction tude 8, cylinder piston 18 in the cylinder promotes piston 5 by ejecting rod of cylinder 10, oil sealing 11 and the valve 4 of having closed make passive storehouse 13 form airtight environment and pressure is raise, and send through oil outlet 1 with the direction of oil stream signal.When driver's playback clutch pedal, initiatively the pressure in storehouse 9 reduces, the body of calming the anger that air control valve 19 discharges in the cylinder 7, and hydraulic piston is promoted to reset by piston reset spring 16, and valve 4 is made the oil hydraulic cylinder oil circuit keep original opening state by 2 pullings of valve control bolt.
Among Fig. 2, piston 5 resets and realizes by oil hydraulic cylinder Returnning spring 16, when the pressure in the cylinder 7 reduces, cylinder piston and hydraulic cylinder piston Returnning spring 16, reset by ejecting rod of cylinder 10 and piston reset shelves lid 22 pulling pistons 5, valve 4 is opened by piston location and valve control bolt 2, makes the oil hydraulic cylinder oil circuit keep original opening state.
