Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.In the detailed description below, some example embodiment of the utility model has only been described through the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation of spirit that does not depart from the utility model and scope, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
Shown in accompanying drawing; Automobile is with clutch power-assisted wheel cylinder; Comprise oil hydraulic cylinder 2, said oil hydraulic cylinder 2 afterbodys are connected with servo-assisted cylinder 5, are provided with boosting piston 4 in the wherein said servo-assisted cylinder 5; Between the inner arm of said boosting piston 4 and said servo-assisted cylinder 5 Returnning spring is installed, said boosting piston 4 connects the clutch connecting lever through clutch power-assisted output push rod 6.
Be provided with hydraulic cylinder piston 3 in the said oil hydraulic cylinder 2; Be provided with return spring between said hydraulic cylinder piston 3 and said oil hydraulic cylinder 2 inwalls; Said oil hydraulic cylinder 2 outer walls are provided with the oil-feed interface 1 that is connected with the clutch master cylinder; Said oil hydraulic cylinder 2 is connected to the drive unit that said servo-assisted cylinder 5 provides power, and said boosting piston 4 is an integral structure with said hydraulic cylinder piston 3.
Said drive unit comprises and is installed in the air intake control valve 8 that air is got into; Said air intake control valve 8 is connected with air intake control valve piston 10; Said air intake control valve 10 connects said servo-assisted cylinder 5 through gas pipeline 9, and said gas pipeline 9 also is connected with outlet valve 7, and said outlet valve 7 is an one-way valve structures; Exhaust outward; Can not air inlet, two cavitys about said boosting piston 4 is divided into said servo-assisted cylinder 5, said air intake control valve 8 connect the right cavity of said servo-assisted cylinder 5 through said gas pipeline 9.Clutch power-assisted wheel cylinder is connected in the automobile hydraulic clutch pipeline, plays the power-assisted effect during automatic clutch.
The working principle of present embodiment is following:
Oil-feed interface on the oil hydraulic cylinder links to each other with the automatic clutch master cylinder, and clutch power-assisted output push rod is connected with clutch connecting lever on the clutch, and the suction port of air intake control valve is connected with the air compressor of motor.
Clutch power-assisted wheel cylinder is (no clutching force output) when original state, and when promptly clutch pedal was in the home position, air intake control valve was closed, and left and right two cavitys of servo-assisted cylinder are in atmospheric pressure state.
When stepping on clutch pedal; Brake fluid flows into oil hydraulic cylinder from the clutch master cylinder, and hydraulic cylinder piston drives servo-assisted piston and moves to clutch power-assisted output push rod direction under hydraulic pressure, and this moment, air intake control valve still was in closed condition; The right cavity A of whole servo-assisted cylinder is in negative pressure state; But because the unidirectional conducting effect of outlet valve, ambient air can not get into the right cavity A of servo-assisted cylinder through outlet valve, so water, dust etc. can not get into servo-assisted cylinder with ambient air; Just can not cause getting rusty of parts such as servo-assisted cylinder and servo-assisted piston yet, and then reduce the probability that lost efficacy and scrap.
Meanwhile; The brake fluid that enters into oil hydraulic cylinder also acts on the air intake control valve piston, promotes the air intake control valve piston and is moved to the left, and continues to move air intake control valve is opened; Pressurized air in the air compressor gets into the right cavity A of servo-assisted cylinder through oral area, the gas pipeline of the air intake control valve opened; Its pressure is raise, and the left cavity B of servo-assisted cylinder keep atmospheric pressure state constant, under left and right cavity two action of pressure of servo-assisted cylinder; Servo-assisted piston drives clutch power-assisted output push rod and is moved to the left, and at this moment acting on has two power on the servo-assisted piston: the one, and the hydraulic action that the clutch master cylinder transmits; Another is air pressure assisted.
When unclamping clutch pedal, clutch master cylinder hydraulic coupling descends, and the state of equilibrium of air intake control valve is destroyed.Air intake control valve piston and assembly thereof move to right, and air intake control valve is closed, and pressurized air enters atmosphere through outlet valve, and the pressure reduction in left and right two chambeies of servo-assisted cylinder reduces, and the power-assisted effect is reduced, and clutch intensity weakens.When clutch pedal loosened fully, all movement parts were resetting under return spring or the action of reset spring separately, and clutch power-assisted wheel cylinder returns to original state, in order to the usefulness of next clutch.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
