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 the groove that a kind of anti-shear ability is strong and manufacture difficulty is low
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 groove structure 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, it is characterised in that：The steel back is integrally formed with bearing pin, and the steel back is just
Face end face is provided with the groove for making friction piece embedded.
Technical solutions of the utility model further improvement is that：The groove includes wave channel.
Technical solutions of the utility model further improvement is that：The groove includes M shape groove.
Technical solutions of the utility model further improvement is that：The groove includes circular trough.
Technical solutions of the utility model further improvement is that：The groove includes cannelure.
As a result of above-mentioned technical proposal, the technological progress that this utility model is obtained is：
Steel back is integrally formed with bearing pin in this utility model, reduces manufacture difficulty, while will arrange for friction in steel back
Body is embedded in internal groove, changes steel back structure while increased the contact area of steel back and friction piece, improves friction piece in powder
Last current state makes friction piece preferably be sintered together with steel back to the diffusion of steel back, improves the sintering efficiency of friction piece, reduces rubbing
The production cost and mass loss rate of pad.
Arrange on the front end face of steel back in this utility model make friction piece embedded for wave channel when, friction piece is in powder
In the embedded wave channel of state, fully combined with wave channel inwall by compacting sintering, increased the contact surface of friction piece and steel back
Product, while the inwall of wave flute profile can resist the shearing force from friction piece multiple directions, makes the combination of friction piece and steel back
It is more firm；Arrange on the front end face of steel back in this utility model make friction piece embedded for M shape groove when, equivalent to steel
Back of the body center is that origin multiple bar-shaped trough compositions equally distributed at an angle are overall, and M shape groove inwall with friction piece by filling
Tap touches the contact area of increase friction piece and steel back, increases the bond strength of friction piece and steel back, while M shape groove passes through
Embedded friction piece resists the shearing force from friction piece from multiple orientation, increases the life-span of friction plate；Steel in this utility model
Arrange on the front end face of the back of the body make friction piece embedded for circular trough when, circular trough can be arranged in into steel back front with irregular
On end face, it is also possible to by circular trough being arranged on the end face of steel back front according to definite shape rule, be embedded in the friction of circular trough
On the one hand body strengthens the bond strength with steel back by increase and the contact area of steel back, on the one hand by embedded circular trough
Shearing force during the opposing work of part, increases the service life of friction plate；Arrange on the front end face of steel back in this utility model
Make friction piece it is embedded for cannelure when, can be embedding with one group of cannelure, or multigroup cannelure of arranged concentric, friction piece
Enter to be made in cannelure friction piece to increase with the contact area of steel back, simultaneously because cannelure is with steel back Chinese and Western as circle, be embedded in
When shearing force is resisted, stress evenly, can extend the use time of friction piece to the friction piece of cannelure.
