Description
Technical field
The invention belongs to skidding technical field, it is related to a kind of brake pad structure, more particularly, to a kind of damper brake
Piece.
Background technology
EMUs are mainly taken with the important braking member that brake lining is in brake apparatus and brakes, its braking ability
Certainly in brake lining and the material and performance of brake disc.In the case where the material and performance of brake lining and brake disc are determined, brake lining structure
Reliability be to influence one of principal element of braking quality, in high speed brake process, brake lining to bear larger shearing force,
Higher temperature and pressure, this just proposes very high requirement to the structure to brake lining, should intensity it is reliable, ensure have very again
Good thermal conductivity, to ensure braking quality of the brake lining when high speed is braked.
Now widely used high speed brake lining structure is generally that the brake block direct weighting of powder metallurgy is sintered on skeleton,
Then skeleton is riveted on a face of polygon tabular steel back by rivet, there are several between brake shoes and brake shoes
Chip removal and preventing hot deformation groove, are welded or have been riveted a W by several through holes on another face of polygon tabular steel back
Shape coattail board.Patent of invention such as Application No. 201110361559.3 discloses a kind of composite floating type brake pad.
Triangle brake block is used into rivet on a face of polygon tabular steel back in said structure, and made
Brake block will bear very big frictional force when dynamic, so that rivet element bears very big shearing force, this easily causes brake lining
Deformation, while very high to the quality requirement of rivet.Although brake facial disfigurement can be eliminated by follow-up mach mode, steel back
Deformation can not eliminate, after the steel back of deformation is installed on brake apparatus, finished brake lining can not completely with braking
Disk is contacted, and braking quality is unstable, braking efficiency reduction, and under high speed, high brake energy, high pressure, this phenomenon is more
Plus it is serious, there is great potential safety hazard.Meanwhile, to prevent brake shoes from being rotated in brake process, each brake block will lead to
Three rivets are crossed in steel back, not only causes all rivets on whole brake lining to be difficult to overall riveting, need to each make
Motion block is individually riveted, and efficiency of assembling is low, high processing costs, and brake lining integrally also easily deforms after riveting, influence brake
Performance.
The content of the invention
In order to solve the above problems, the invention provides a kind of brake pad so that reached that brake is steady, safety can
Lean on, the effect that efficiency of assembling is high, processing cost is low.
The present invention is achieved by following technical solution.
A kind of brake pad, including locking element, steel back component and some brake shoes, the brake shoes lead to steel back component
Locking element connection locking is crossed, support base is provided between the brake shoes and steel back component.
The support base is to be equipped with one group of bulge-structure on disk-like structure, two faces；The brake shoes include backboard and
Brake pad, the backboard is fixedly connected with brake pad, and brake shoes corresponding with bulge-structure on support base is machined with brake shoes
Groove；The steel back component includes steel back and coattail board, and steel back is fixedly connected with coattail board, and some groups and branch are machined with steel back
Support the corresponding steel back groove of bulge-structure on seat.
The locking element is rivet；Every group of the bulge-structure is at least 3, is punching press or machine with support base one
Process；Distribution of the bulge-structure on support base two sides, structure snd size are identical, and position is staggered；The backboard with
Brake pad is connected by sintering；The steel back passes through rivet with coattail board.
The beneficial effects of the invention are as follows：
A kind of brake pad of the present invention, prevents brake shoes from being rotated relative to steel back component by clamping support,
Add the integral firmness and stability of brake lining；And only pass through a center rivet between steel back component, support base, brake shoes
Connection, on the one hand, greatly reduce the number of rivets needed to use, also reduce the quality requirement to used rivet, drops
Low product cost；On the other hand, the difficulty of overall riveting is substantially reduced, and is not only increased efficiency of assembling, is also reduced brake lining
Deformation in riveting process, improves assembly qualified rate, so as to ensure that brake lining braking ability is stable, brake safe is reliable.

Embodiment
Technical scheme is further described below in conjunction with the accompanying drawings, but claimed scope is not limited to institute
State.
As shown in figures 1-4, a kind of brake pad of the present invention, including locking element 5, steel back component 9 and some stop
Car block 8, the brake shoes 8 is connected locking with steel back component 9 by locking element 5, between the brake shoes 8 and steel back component 9
Provided with support base 4；The locking element 5 is rivet, because locking element 5 is not by shearing force, can use and meet connection request
Conventional rivets connection, to reduce cost.
The support base 4 is to be equipped with one group of bulge-structure 4a on disk-like structure, two faces, and every group of bulge-structure 4a is at least
