Abstract
The invention discloses an automobile main cylinder assembly, which comprises a cylinder body, wherein an installation base is arranged on the side wall of the cylinder body; an oil cavity is formed in the cylinder body; a cylinder body front cover is fixedly arranged in an opening formed on the cylinder body at the left end of the oil cavity; an oil outlet is formed at the left end of the cylinder body front cover; a residual valve is arranged at the oil outlet; a piston assembly is arranged in the oil cavity at the right end of the cylinder body in a sliding mode; a spring base is arranged at the left end of the piston assembly; a spring is arranged on the spring base; the left end of the spring butts against the oil outlet; an oil inlet pipe is communicated on the side wall of the cylinder body; and a plurality of seal rings are arranged on the side wall of the piston assembly. The automobile main cylinder assembly has a simple and compact structure, is small in volume and can prevent dust invasion and oil leakage effectively.
Description
Technical field
The present invention relates to a kind of automobile master cylinder assembly.
Background technique
What clutch used in the present automobile operation mechanism all is conventional clutch slave cylinder, and the piston in its structure only is provided with seal ring between inner walls, occur oil leakage phenomenon in the course of the work easily; In addition, in the linkage structure of existing piston and push rod; Behind the gap that the clutch plate wearing and tearing are produced, can not carry out replenishing automatically, the shortcoming of this system is complex structure; Wheel cylinder center and separator levers are difficult to guarantee concentricity; Produce noise and impact, make wheel cylinder produce eccentric wear easily, thereby influence the working life of wheel cylinder.
Summary of the invention
The present invention provides a kind of problem to leakage of oil in the above-mentioned clutch slave cylinder working procedure, provide simple in structure, compact, volume is little, can effectively prevent the clutch slave cylinder assembly of into grey and leakage of oil.
Technical solution problem of the present invention provides following scheme:
A kind of automobile master cylinder assembly comprises cylinder body, and the sidewall of said cylinder body is provided with fitting seat; The inside of said cylinder body is provided with oil pocket, it is characterized in that: the left end cylinder body of said oil pocket is provided with the opening internal fixation cylinder body protecgulum is installed, and the left end of said cylinder body protecgulum is provided with oil outlet; Said oil outlet place is provided with residual valve, is slidingly fitted with piston assembly in the oil pocket of said cylinder body right-hand member, and the left end of said piston assembly is provided with spring seat; Said spring seat is provided with spring; Said spring for the left end of said spring withstands on the oil outlet oral area, the sidewall of said cylinder body is attend UNICOM's oil inlet pipe, the sidewall of said piston assembly is provided with multiple-sealed circle.
On the said oil outlet fuel discharge port is installed, said fuel discharge port is covered with stifle, covers dust-proof cover on the right-end openings of said cylinder body, and the center of said dust-proof cover is provided with push-rod hole.
Working principle of the present invention: when the oil inlet hole oil-feed, the leather cup on the piston is further opened, pressure is high more; Sealing effect is good more, and the present invention is provided with residual valve at the oil outlet place, efficiently solves the residue problem of hydraulic oil in the cylinder body; Termination at cylinder body is provided with dust-proof cover, can effectively prevent dust, makes and produces pressure in the cylinder body active chamber; Promoting piston and push rod outwards moves; Thereby the effect that the power that reaches the cut-out motor transmits to speed changer, the spring in the described active chamber plays buffer function when pistons work, reduce noise and impact.
Description of drawings
Fig. 1 is a structural representation of the present invention.
