Abstract
The utility model is related to a kind of master cylinders of nonmetallic materials spring retainer seat, belong to brake system of car.Primary cup and secondary leather cup are respectively assembled in Master cylinder body, and in second piston component and first piston component assembling to Master cylinder body, connector sleeve is installed on Master cylinder body；It is characterized in that：The structure of second piston component is the axial riveting of gag lever post and small washer one and 35 fiber nylon spring retainer seat one that second piston spring passes through second piston；The structure of first piston component is the axial riveting of gag lever post and small washer two and 35 fiber nylon spring retainer seat two that first piston spring passes through first piston.The utility model has the advantage of：Structure novel, improve the material of spring retainer seat, ensure the function of connection piston and piston spring while reducing the weight of master cylinder, when avoiding vehicle braking, part contact with each other friction caused by abnormal sound and clamping stagnation problem, reduce cost, processing is simple, molding is easy, high in machining efficiency, good quality of product.
Description
Technical field
The utility model belongs to brake system of car, refers in particular to a kind of brake master cylinder assy.
Background technology
In brake system of car, spring retainer seat connects piston spring and piston in brake master cylinder assy, realizes system
Limit and reset in the dynamic master cylinder course of work to spring.Brake master cylinder assy is during piston motion, metal spring limit
There are intermetallic friction abnormal sounds, metal spring limit base to have become bottleneck work due to punching technology between seat and piston limit bar
Sequence, gag lever post riveted holes concentricity are difficult to guarantee consistency, and leading to master cylinder, gag lever post connects with limit bore during the work time
Wiping is touched, abnormal sound even clamping stagnation is generated.This abnormal sound and clamping stagnation are generally deposited in the brake master cylinder assies such as center valve type, plunger type
The problem of, seriously affected the raising of the product quality of brake, there is an urgent need to rational scheme solutions to abnormal sound problem herein
Certainly.
Invention content
The utility model provides a kind of master cylinder of nonmetallic materials spring retainer seat, to solve metal spring limit base
There are problems that intermetallic friction abnormal sound generates clamping stagnation between piston limit bar.
The technical solution of the utility model is：Primary cup and secondary leather cup are respectively assembled in Master cylinder body, second piston component
In first piston component assembling to Master cylinder body, connector sleeve is installed on Master cylinder body；The structure of second piston component is that second lives
Fill in gag lever post and small washer one and 35 fiber nylon spring retainer seat one axial riveting of the spring by second piston；First piston portion
The structure of part is the gag lever post and small washer two and 35 fiber nylon spring retainer seat, two axis that first piston spring passes through first piston
To riveting；
The 35 fiber nylon spring retainer seats one are identical as 35 fiber nylon spring retainer two structures of seat；
The structure of the 35 fiber nylon spring retainer seats one is that have loss of weight on 35 fiber nylon spring retainer seats one
Hole has been uniformly distributed 6 reinforcement platforms on the end face of spring retainer seat one, and the wall thickness of 35 fiber nylon spring retainer seats one is L, L
For 1mm.
The utility model has the advantage of：Structure novel improves the material of spring retainer seat, ensures connection piston and work
Fill in the function of spring reduces the weight of master cylinder simultaneously, and when avoiding vehicle braking, part contacts with each other caused by friction
Abnormal sound and clamping stagnation problem reduce cost compared with conventional brake master cylinder, and processing is simple, and molding is easy, high in machining efficiency, production
Quality is excellent.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model second piston component；
In figure, Master cylinder body 1, second piston component 2, primary cup 3, connector sleeve 4, first piston component 5, secondary leather cup 6,35 glass
Fine nylon spring retainer seat 1, second piston spring 202, small washer 1, second piston 204,35 fiber nylon springs limit
Position seat 2 501, small washer 2 503, first piston 504, lightening hole 20101, reinforces platform 20102 at first piston spring 502.
Specific implementation mode
Primary cup 3 and secondary leather cup 6 are respectively assembled in Master cylinder body 1, and second piston component 2 and first piston component 5 assemble
Into Master cylinder body 1, connector sleeve 4 is installed on Master cylinder body 1；The structure of second piston component 2 is that second piston spring 202 passes through
The gag lever post and small washer 1 and 35 fiber nylon spring retainer seat 1 of two pistons 204 are axial to be riveted；First piston portion
The structure of part 5 is the gag lever post and small washer 2 503 and 35 fiber nylon springs that first piston spring 502 passes through first piston 504
The axial riveting of limit base 2 501；
35 fiber nylon spring retainer seats 1 are identical as 35 fiber nylon spring retainer 2 501 structures of seat, 35 glass Buddhist nuns
The structure of imperial spring retainer seat 1 is that have lightening hole 20101, spring retainer seat on 35 fiber nylon spring retainer seats 1
The wall thickness that 6 reinforcement 20102,35 fiber nylon spring retainer seats 1 of platform have been uniformly distributed on one 201 end face is L, and L is
1mm。
Operation principle：Second piston component 2 and primary cup 3, secondary leather cup 6 form a separate chamber, first piston component 5 with
Primary cup 3, secondary leather cup 6 form a separate chamber, and brake fluid storage device is connected by connector sleeve 4 with two chambers, supply two chamber systems
Hydrodynamic, two chambers are full of 5 certain distance of first piston component is pushed after brake fluid after, two chambers set up hydraulic pressure respectively, and hydraulic pressure passes through
Brake piping is transferred to wheel, to realize automobile brake.
