Abstract

The utility model discloses a clutch main cylinder assembly, which comprises a cylinder body, an oil cup assembly and a push rod fork assembly. A work cavity is arranged inside the cylinder body, the oil cup assembly is communicated with the work cavity via an oil inlet through hole, a hoop component is arranged between the oil cup assembly and an oil inlet opening, and a middle core valve type piston component is arranged inside the work cavity. The middle core valve type piston component further comprises a piston; a rear sealing belt ring and a front sealing belt ring are arranged on the piston; a one-way valve core is arranged at the front end of the piston; a one-way valve belt ring is arranged on the one-way valve core; a spring seat is arranged at the front end of the piston; a one-way valve spring is arranged on the inner side of the spring seat; a return spring is arranged between the piston and the front end portion of the work cavity; and the return spring is placed on the outer side of the spring seat of the piston. By modifying the structure of a piston component, the clutch main cylinder assembly adopts an one-way valve to realize oil compensation, avoids a processing compensation hole needed by a conventional clutch main cylinder body, and decreases processing difficulty of the clutch main cylinder body.

Description

The clutch master cylinder assembly
Technical field
The utility model relates to a kind of clutch master cylinder assembly.
Background technique
Traditional clutch master cylinder structure, on master cylinder body, be equipped with compensate opening, when rapid engage the clutch, clutch pedal retrun spring comparatively fast moves to right master cylinder piston by master cylinder push rod, and certain resistance is arranged owing to fluid flows in pipeline, it is slower to flow, and makes the piston left side may form certain degree of vacuum.Under the action of pressure of the left and right sides, a small amount of fluid flows to the piston left side to remedy vacuum by the one-way valve of oil inlet hole process master cylinder piston, when being pressed onto fluid that clutch release slave cylinder goes by master cylinder when one-way valve flows into, the total oil mass in left chamber is too much, and these unnecessary oil promptly flow back to liquid container from compensate opening; When causing the volume-variation of fluid because of leakage of oil or because of temperature variation in the hydraulic system, then borrow compensate opening to make in time that oil mass obtains suitable increase and decrease in the whole oil circuit, to guarantee the reliability of normal oil pressure and hydraulic work system.But, this casting processing complexity that adds the clutch master cylinder cylinder body of compensate opening, and difficulty of processing is big.
The model utility content
The purpose of this utility model is in order to overcome technological deficiency recited above, a kind of clutch master cylinder assembly that need not process compensate opening to be provided.
In order to solve technical problem recited above, the utility model is taked following technological scheme:
The utility model provides a kind of clutch master cylinder assembly, include cylinder body, be installed in the lubricating cup assembly on the cylinder body, be placed in the push rod fork assembly of rear end of the cylinder block, in cylinder body, has active chamber, the lubricating cup assembly is communicated with active chamber by the oil-feed through hole, is provided with hoop component between the filler opening of lubricating cup assembly and cylinder body, is provided with SMIS valve type bucket assembly in active chamber, described SMIS valve type bucket assembly further includes piston, and the rear end of piston connects push rod fork assembly; Piston is provided with back sealing apron, preceding sealing apron; Have nonreturn valve core in piston nose, nonreturn valve core is provided with the one-way valve apron; Be provided with spring seat in piston nose, the spring seat inboard is provided with the check valve spring that is connected with nonreturn valve core; Be provided with return spring between piston and the active chamber front end, return spring is placed in the spring seat outside.
As a kind of preferred version, offer spacing slotted eye on the described piston, offer spacing hole in the bottom of the cylinder body corresponding with the spacing slotted eye of piston, spacing hole is provided with stop screw.As a kind of more excellent scheme, after stop screw fits into spacing hole, be positioned at the rear end of oil-feed through hole.
Clutch master cylinder of the present utility model adopts one-way valve to realize the fluid compensation by improving the structure of piston assembly, has avoided traditional clutch master cylinder cylinder body need process compensate opening, has reduced the difficulty of processing of clutch master cylinder cylinder body.
Description of drawings
Fig. 1 is the main TV structure figure of the utility model clutch master cylinder assembly.
Fig. 2 is the side-looking structural drawing of Fig. 1.
Fig. 3 is piston assembly structure figure of the present utility model.
Among the figure, 1. cylinder body, 2. dust-proof cover, 3. the hole with back-up ring, 4. piston, 5. back sealing apron, 6. before sealing apron, 7. lubricating cup assembly, 8. hoop component, 9. return spring, 10. spring seat, 11. check valve springs, 12. nonreturn valve cores, 13. one-way valve aprons, 14. stop screws, 15. rubber washers, 16. push rods fork assembly, 17. seal rings, 18. oil-feed through holes, 19. oil outlets, 20. spacing slotted eyes.
Embodiment
See also Fig. 1, Fig. 2 and Fig. 3.As shown in the figure, clutch master cylinder assembly of the present utility model includes cylinder body; Be installed in the lubricating cup assembly on the cylinder body; Be mounted with push rod fork assembly 16 in cylinder body 1 rear end, and be provided with dust-proof cover 2 in the rear end of cylinder body 1; Be provided with porose with back-up ring 3 in the installation place of push rod fork assembly 16 and cylinder body 1; Front end at cylinder body 1 has oil outlet 19, is provided with seal ring 17 in oil outlet 19; Have active chamber in cylinder body 1, lubricating cup assembly 7 is communicated with active chamber by oil-feed through hole 18; Be provided with hoop component 8 between the filler opening of lubricating cup assembly 7 and cylinder body, in active chamber, be provided with SMIS valve type bucket assembly.SMIS valve type bucket assembly further includes piston 4, and the rear end of piston 4 connects push rod fork assembly 16; Piston 4 is provided with back sealing apron 5, preceding sealing apron 6; Have nonreturn valve core 12 at piston 4 front ends, nonreturn valve core 12 is provided with one-way valve apron 13; Be provided with spring seat 10 at piston 4 front ends, spring seat 10 inboards are provided with the check valve spring 11 that is connected with nonreturn valve core 12; Be provided with return spring 9 between piston 4 and the active chamber front end, return spring 9 is placed in spring seat 10 outsides of piston; Offer spacing slotted eye 20 on the piston 4, offer spacing hole in the bottom of the cylinder body 1 corresponding with the spacing slotted eye 20 of piston, spacing hole is provided with stop screw 14, after stop screw 14 fits into spacing hole, is positioned at the rear end of oil-feed through hole 18.
