Background technology
Master cylinder is one of vitals of automobile, in work process, back piston spring assembly when automobile brake at
In compressive state, when releasing braking, spring is by compressing recovery Pre strained state, in this course, and the location bar of spring assembly
And nut is affected very big by the counteracting force of spring during backward stroke of the piston and brake fluid pressure, if assembling unreliable, will cause making
Dynamic master cylinder brake fade, produces serious traffic safety accident.
Spring assembly includes positioning bar, spring, spring base I and spring base II, and spring base I and spring base II are by location bar
Connecting, the idle stroke size of spring assembly depends on spring base I and spring base II length dimension apart, existing spring assembly
Mostly it is by using pad to regulate spring base I and spring base II length apart.(if patent publication No. is CN101338803A
Patent of invention, a kind of automobile brake system spring assembly provided, is to set pad at thrust sleeve and pin riveting).
This kind of structure spring assembly there is the problem that equipment adjustment is inconvenient, it is difficult to ensures master cylinder idle stroke
Concordance, the pad once selected is improper, needs riveting mouth is rooted out replacing, causes location bar to be scrapped.
Summary of the invention
It is an object of the invention to provide and a kind of improve automobile brake reliability and durability, the master cylinder of simple in construction
Spring assembly and assemble method thereof, to solve the above-mentioned deficiency existing for prior art.
The technical scheme solving above-mentioned technical problem is:
A kind of master cylinder spring assembly, including spring base I, location bar, bullet and spring base II；The lower end of described location bar sets convex
Platform, its upper end is the end of thread, spring base I inner hole sleeve location bar lower end and pass through boss spacing, spring base II inner hole sleeve exists
The upper end of location bar is also connected with the location bar end of thread by nut, spring housing position bar periphery and be limited in spring base I and
Between spring base II；The port of the described location bar end of thread has riveting mouth.
Its further technical scheme is: bar boss bottom surface, described location has notch.
It another solution is that the assemble method of a kind of master cylinder spring assembly, comprises the steps:
(1) location bar is pierced into spring base I endoporus, put spring and spring base II successively；
(2) above stated assembly is placed on the tooling base driven by cylinder, spring base I under, spring base II is upper, by gas
Cylinder moves spring-compressed, makes the end of thread of location bar stretch out spring base II endoporus, the end of thread of the location bar being screwed into by nut；
(3) hold out against the notch of bar bottom, location by frock, require that fine-tuning nut adjusts the length dimension of spring assembly according to design；
(4) with drift, the riveting mouth riveting of location bar is put down, make nut and the connection positioning bar fix, exit tooling base；
(5) using auxiliary mould inspection, riveting puts in place, is completed.
Owing to using technique scheme, compared with prior art, the one master cylinder spring assembly of the present invention and
Assemble method has the advantages that
(1) spring assembly location bar is connected with spring base II by the end of thread and nut, easy to adjust, and the location bar end of thread is provided with
Riveting mouth, location bar is connected with nut by riveting, firm and reliable connection, the size of spring assembly, steady quality, master cylinder
The concordance of idle stroke is guaranteed, and not only reduces the fault rate of master cylinder product, and it is reliable to improve automobile brake
Property and durability thus improve vehicle travel safety；
(2) simply, assembling regulation process only needs a people to complete for its simple in construction, assemble method；
(3) due to master cylinder spring assembly size adjustable, the SMIS valve type master cylinder product being suitable for Multiple Type uses.
Below, a kind of master cylinder spring assembly and the technology of assemble method thereof to the present invention in conjunction with the accompanying drawings and embodiments
Feature is further described.
