Description
Technical field
The present invention relates to brake lining technical field more particularly to a kind of brake lining structures of detachable brake shoes.
Background technique
EMU is mainly taken with the important braking member that brake lining is in brake apparatus and braking system, braking ability
Certainly in the material and performance of brake lining and brake disc.In the case where the material and performance of brake lining and brake disc determine, brake lining structure
Reliability be influence braking quality one of principal element.Speed is high when due to high-speed train braking, and brake lining will bear larger
Shearing force, higher temperature and pressure, this just proposes very high requirement to the structure of brake lining, should intensity it is reliable, again
Guarantee has good thermal conductivity, to guarantee braking quality of the brake lining when high speed is braked.Need will be huge for brake lining in braking process
Big friction kinetic energy is converted to thermal energy, and the brake shoes thermic load on brake lining is huge, and the brake shoes being easy to cause on brake lining first rubs
For rub body because temperature sharply increases, heat cannot shed in time causes brake shoes first friction unit quick abrasion, cracking occurs, falls side and fall
Angle and first friction unit obscission.
Brake shoes is using riveted structure on widely used 200km/h~300km/h EMU brake lining domestic at present,
Mostly then skeleton is riveted on more by the direct temperature-pressure sintering of the first friction unit of powder metallurgy on skeleton by rivet
On one face of side shape plate steel back.To prevent brake shoes from rotating in brake process, every brake shoes need to process three or more
A riveted holes not only make all rivets on entire brake lining be difficult to realize whole riveting through three rivets in steel back
It connects, needs each brake shoes individually to rivet, and brake shoes upper skeleton and washer contacts area are larger, cause brake shoes skeleton and steel back
Between gap it is smaller.As shown in Fig. 1-Fig. 3.
Under condition of market economy, the height of product purchasing cost directly affects the good of railway operation department economic benefit
It is bad.Railway operation department will increase economic efficiency, it is important that be a little exactly to reduce purchase cost.Purchase cost is reduced to have become
Railway operation department survives and seeks the key subjects of long term growth, is the important of raising railway operation department competitiveness
The important channel of premise and economic benefit.One brake lining of railway operation department buying, brake block cost only account for a brake lining
The one third of purchase cost, the expense of remaining components of brake lining account for 2/3rds of brake lining purchase cost.Brake lining is vulnerable part
Product, because frequent retarding braking causes first friction unit abrasion on brake shoes very fast in driving conditions, in order to ensure train safety
Operation must frequently replace full wafer brake lining, increase railway operation department train operation cost.
Summary of the invention
The problem of the purpose of the present invention is to solve frequently replacement brake lining increases train operation cost in the prior art,
And a kind of brake lining structure of the detachable brake shoes proposed.
To achieve the goals above, present invention employs following technical solutions:
A kind of brake lining structure of detachable brake shoes, including brake shoes, steel back and fixed plate, the brake shoes include first
Friction piece and the first skeleton, first skeleton are fixedly connected on the bottom of first friction unit, offer in the steel back multiple
The internal sleeve of first rivet hole, first rivet hole is equipped with the first rivet, and the fixed plate is fixedly connected by the first rivet
In steel back, punching has the identical boss of multiple sizes in the fixed plate, offers mounting hole in the middle part of the boss, each
Equal punching stretch goes out an installation cavity between the boss and steel back, and the multiple of connection installation cavity are offered on the boss
The inside of groove, each installation cavity is provided with disk spring, and first skeleton is set in the inside of installation cavity,
The first friction unit stretches out boss by mounting hole, is fixedly connected on the side wall of first skeleton multiple opposite with groove
The fixed feet answered, the two sides of the disk spring offset with the first skeleton and steel back respectively.
Preferably, multiple second rivet holes are also provided in the steel back, the internal sleeve of second rivet hole is equipped with the
Two rivets, side of the steel back far from fixed plate are fixedly connected with coattail board by the second rivet.
Preferably, the quantity of the groove and the quantity of fixed feet are equal, and the quantity of the groove is the integer greater than 1.
Preferably, the depth of the installation cavity is less than the sum of fixed feet and the thickness of disk spring.
Preferably, the brake shoes and boss clearance fit.
Compared with prior art, the present invention provides a kind of brake lining structures of detachable brake shoes, have following beneficial to effect
Fruit:
1, the brake lining structure of the detachable brake shoes can be replaced on brake lining and be ground by the way that demountable brake shoes is arranged
It damages the brake shoes of the limit, and does not have to integral replacing brake lining, purchase cost is reduced with this；By being arranged brake shoes in boss
It is interior, and certain distance is set between adjacent boss, the heat-sinking capability of brake lining can be improved, reduce the mill of friction piece on brake shoes
Damage extends the service life of brake shoes and brake lining, further cuts operating costs.
It is not directed to part in the device to be the same as those in the prior art or can be realized by using the prior art, the present invention passes through
The brake shoes that can be replaced is set, and extends the service life of brake shoes and brake lining to cut operating costs.
