Description
Technical field
This utility model is related to Vehicular brake device technical field, especially a kind of mosaic texture powder metallurgy brake pad
Friction plate.
Background technology
The friction plate of powder metallurgy brake pad be after by powder frictional material pressure forming, then in sintering furnace with
Backboard is sintered into one, it is desirable to which backboard is firmly bonded with friction material, and anti-shearing force is strong during frictional damping, does not fall block.
In existing powder metallurgy brake pad, back board structure is made up of backboard and connection bearing pin, and connection bearing pin passes through backboard
Centre bore, end face that backboard is combined with friction material keeps concordant, and friction material sinters are on the end face of backboard.
Because the end face of backboard and the end face of friction material are plane, prevent from cutting completely by sinter layer between the two
Cut, the shearing force that can be born is extremely limited；Simultaneously in sintering pendulum stove, because backboard cannot be mutually located with friction material,
Put more difficult, and backboard and friction material easily produce mobile dislocation, so as to influence whether brake lining sintering quality and efficiency.
Utility model content
This utility model technical issues that need to address are to provide that a kind of anti-shear ability is strong and manufacture difficulty is low inlays
The friction plate of structure powder metallurgy brake pad.
To solve above-mentioned technical problem, the technical scheme that this utility model is adopted is：
The friction plate of mosaic texture powder metallurgy brake pad, including the pin at the steel back of platy structure and the connection steel back back side
Axle, also including the positive friction piece of connection steel back, the friction piece is partially submerged into inside steel back, it is characterised in that：The steel back
It is integrally formed with bearing pin, the front end face of the steel back is provided with the passage through steel back end face for making friction piece embedded.
Technical solutions of the utility model further improvement is that：The passage includes manhole.
Technical solutions of the utility model further improvement is that：The passage includes strip through-hole.
Technical solutions of the utility model further improvement is that：The passage includes annular through hole.
Technical solutions of the utility model further improvement is that：The passage includes bar v notch v.
Technical solutions of the utility model further improvement is that：The passage includes vee.
As a result of above-mentioned technical proposal, the technological progress that this utility model is obtained is：
This utility model changes steel back structure, steel back and friction piece is mechanically combined together in pressure forming,
Simplify that existing friction piece is separately formed, steel back and friction piece put respectively the technological process for sintering brake pad into, avoid
During sintering pendulum stove, because steel back cannot be mutually located with friction piece, put more difficult, steel back and friction piece easily produce mobile wrong
The technical barrier of position；Steel back is integrally formed with bearing pin in this utility model, the difficulty for making steel back is reduced, while using in steel back
In the passage for inlaying friction piece, friction piece is preferably sintered together with steel back, improve the sintering efficiency of friction piece, reduce
The production cost and mass loss rate of friction plate.
When arranging manhole for inlaying friction piece in steel back in this utility model, manhole is convenient to be processed, while
Steel back is set to carry out a fixation to friction piece, as long as arranging 2 manholes in the different position of steel back can meet fixed friction
The requirement of body, it is relatively low to steel back processing request；When strip through-hole being set for inlaying friction piece in steel back in this utility model, bar
Shape through hole can make steel back laterally carry out large-area fixation in strip through-hole to friction piece, as long as with different in steel back
Angle arranges at least 2 strip through-holes, you can meets the requirement of fixed friction body, and compares the fixed effect of manhole more
It is good；When arranging annular through hole for inlaying friction piece in steel back in this utility model, annular through hole need to only arrange one i.e.
The requirement of fixed friction body can well be met, when friction plate works, friction piece is embedded in the part stress of steel back evenly, no
Easily drop, increase the service life of friction plate；When bar v notch v being set for inlaying friction piece in steel back in this utility model, bar
V notch v is more convenient when friction piece can be made embedded；Arranging vee in this utility model in steel back is used to inlay friction piece
When, the area of the embedded steel back part of friction piece is increased, increase the bond strength of friction piece and steel back.
