Description
Technical field
The utility model is related to the excessively oily structural assembly of a kind of clutch, master cylinder cannelure, and specifically one kind will
The new assembly structure that oil-feed and repairing passage are substituted using ring channel structures.
Background technology
Clutch general pump is attached to clutch foot plate the part being connected by oil pipe with clutch booster, its effect
It is that collection pedal travel information makes clutch realize separating by the effect of booster.The Main Function of master cylinder is to promote system
Hydrodynamic transmits to each brake cylinder and promotes piston.Clutch on the market at present, the structure of master cylinder include oil return and mend
Repay hole, piston cup, piston assembly, valve member, its basic functional principle is：Piston hydraulic is driven, by piston assembly
Motion be converted into the volume of hydraulic oil and discharge, and certain hydraulic pressure set up by the compression of hydraulic oil export.Close for improving
Feng Xing, clutch, the piston assembly of master cylinder are provided with piston cup, and it reciprocates through located at the pump housing during clutch and brake
On oil return compensate hole.And oil return compensates the frequent friction between hole, it will the abrasion of aggravation piston cup, impact product uses
Life-span and sealing.In addition, existing clutch, master cylinder are provided with valve member in piston assembly front end, this component valve face
Processing and requirement of shelter height, manufacturing cost are high.Meanwhile, brake fluid exists and will be easy to during particulate matter accumulate in valve member
Portion, leads to poorly sealed and lost efficacy.
Content of the invention
The utility model provides the excessively oily structural assembly of a kind of clutch, master cylinder cannelure.
The purpose of this utility model is to solve some clutches on existing market, master cylinder piston cup and piston valve
Assembly easy failure effect service life and the problem of sealing.
The utility model solves its technical problem and be employed technical scheme comprise that：A kind of clutch, master cylinder cannelure
Cross oily structural assembly, including the pump housing, piston assembly, liquid storage kettle, described piston assembly is provided with piston cup, described piston assembly
Pump housing inner chamber is divided into fuel supply chamber and pressure chamber, the pressure chamber side of the described pump housing is provided with oil-out, sets in described pressure chamber
There is the back-moving spring making piston assembly reset, the sidepiece of the described pump housing is provided with the oil-in being connected with liquid storage kettle, the described pump housing
Sidepiece is provided with cannelure, described oil-in on cannelure, described piston assembly front end valveless assembly.
Further, described oil-in is located at cannelure top.
Further, described back-moving spring is turriform spring, and the small end of described turriform spring is connected to piston assembly front end
Spring mounting seat on.
The beneficial effects of the utility model are：Due to the excessively oily structural assembly of clutch, master cylinder cannelure, including pump
Body, piston assembly, liquid storage kettle, described piston assembly is provided with piston cup, and pump housing inner chamber is divided into confession by described piston assembly
Oil pocket and pressure chamber, the pressure chamber side of the described pump housing is provided with oil-out, is provided with piston assembly can be made to reset in described pressure chamber
Back-moving spring, the sidepiece of the described pump housing is provided with the oil-in being connected with liquid storage kettle, and described pump housing sidepiece is provided with cannelure, institute
State oil-in on cannelure, compared with original structure, ring channel structures orthodrome excessively, compensates hole for substituting oil return,
Oil-in directly processes at cannelure top, it is to avoid piston cup seal part is compensated by oil return in assembling and motion process
Hole and produce heavy wear, improve product service life, described piston assembly front end eliminates valve member, with original structure
Compare, piston assembly structure optimizes significantly, improve product hermeticity and reliability, reduce production cost.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to the accompanying drawings and examples the utility model is further illustrated：
As shown in the figure, there is provided the embodiment of the excessively oily structural assembly of the utility model clutch, master cylinder cannelure, bag
Include the pump housing 5, piston assembly 4, liquid storage kettle 9, described piston assembly 4 is provided with piston cup 3, and described piston assembly 4 is by the pump housing 5
Chamber is divided into fuel supply chamber 8 and pressure chamber 7, and pressure chamber 7 side of the described pump housing 5 is provided with oil-out 6, is provided with described pressure chamber 7
Make the back-moving spring 10 that piston assembly 4 resets, the sidepiece of the described pump housing 5 is provided with the oil-in 2 being connected with liquid storage kettle 9, described
The pump housing 5 sidepiece is provided with cannelure 1, described oil-in 2 on cannelure 1, described piston assembly 4 front end valveless assembly.
Described oil-in 2 is located at cannelure 1 top.
Described back-moving spring 10 is turriform spring, and the small end of described turriform spring is connected to the spring peace of piston assembly front end
On dress seat 4-1.
Compared with original structure, ring channel structures orthodrome excessively, compensates hole for substituting oil return, oil-in is directly processed
At cannelure top, it is to avoid piston cup seal part compensates hole by oil return in assembling and motion process and produces and seriously grind
Damage, improve product service life, and cancel the valve member in piston assembly, then greatly optimize piston assembly structure, carry
High product hermeticity and reliability, reduce production cost.
As needed, disclosed herein is specific embodiment of the present utility model, it will be appreciated that the disclosed embodiments are
Demonstration the utility model, the utility model can have different and alternative form enforcement.Accompanying drawing is not necessarily drawn to scale.Therefore,
Concrete structure disclosed herein and function detail be understood not in a limiting sense, but be only used as representative basis with
