Description
Technical field
The utility model 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.
