Description
Technical field
The utility model is related to Vehicular brake device technical field, especially a kind of raised structures 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 friction catch, not chip off-falling.
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
The utility model technical issues that need to address are to provide the projection that a kind of anti-shear ability is strong and manufacture difficulty is low
The friction plate of structure powder metallurgy brake pad.
In order to solve the above technical problems, the technical scheme that the utility model is used is：
The friction plate of raised structures powder metallurgy brake pad, including platy structure steel back and the pin at the connection steel back back side
Axle, also including the connection positive friction piece of steel back, it is characterised in that：The steel back is integrally formed with bearing pin, the steel back front
End face is provided with the projection inside embedded friction piece.
Technical solutions of the utility model further improvement is that：It is described raised including circular protrusions.
Technical solutions of the utility model further improvement is that：It is described raised raised including annular.
Technical solutions of the utility model further improvement is that：It is described raised including strip bulge.
Technical solutions of the utility model further improvement is that：It is described raised raised including M shape.
Technical solutions of the utility model further improvement is that：It is described raised including one or more.
By adopting the above-described technical solution, the technological progress that the utility model is obtained is：
Steel back is integrally formed with bearing pin in the utility model, reduces manufacture difficulty, while being rubbed insertion is set in steel back
Projection inside rub body, changes steel back structure while avoiding the excessive stress concentration of friction piece, make friction piece preferably with
Steel back is sintered together, and improves the sintering efficiency of friction piece, reduces the production cost and mass loss rate of friction plate.
When circular protrusions insertion friction piece inside is set in the utility model in steel back, steel back center can be arranged on, this
When one circular protrusions is set, embedded friction piece inside can fixed friction body well, while circular projection can also be set
In steel back diverse location, at least two circular protrusions are now set, to be embedded in inside friction piece, friction piece is not produced and is turned
Move, further fixed friction body；Set in steel back in the utility model when inside the raised embedded friction piece of annular, by circle
Annular protrusion is arranged on steel back center, and now friction piece and steel back into mutual embedded state, when friction plate works, play with good
Anti-shearing force effect；When strip bulge insertion friction piece inside is set in this practical new middle steel back, one can be set
Or multiple strip bulges, when multiple strip bulges are set, it is parallel to each other between each strip bulge, difficulty of processing reduction, friction
The body faying face mutually embedded with steel back increases, and increases anti-shearing force intensity；M shape is set in this practical new middle steel back convex
When playing embedded friction piece inside, mutually arranged at an angle equivalent to three strip bulges, can resisted from multiple orientation
Shearing force, increase the friction plate life-span.

Specific embodiment
The utility model is described in further details with reference to embodiment：
As shown in figure 1, the friction plate of raised structures powder metallurgy brake pad, including steel back 1, bearing pin 2 and friction piece 3,
Steel back 1 is platy structure, and the back side and the bearing pin 2 of steel back 1 are integrally formed, and front and the friction piece 3 of steel back 1 are connected to by sintering
Together, the front end face of steel back 1 is provided with raised 4 inside embedded friction piece 3, and raised 4 are used to make steel back 1 be combined with friction piece 3
It is more firm.
As shown in Fig. 2, Fig. 5, the projection 4 on the front end face of steel back 1 inside embedded friction piece 3 includes circular protrusions, described
Circular protrusions can be provided in of the center of steel back 1, it is also possible to be separately positioned on the diverse location of steel back 1 at least two
It is individual, behind circular protrusions insertion friction piece 3 inside, wrapped up by friction piece 3, play a part of fixed friction body 3；If be provided in
At least two circular protrusions of the diverse location of steel back 1, may also operate as preventing friction piece 3 around the problem of central rotation.
As shown in figure 3, the projection 4 on the front end face of steel back 1 inside embedded friction piece 3 includes that annular is raised, annulus is convex
Rising can set one or more and be arranged concentrically with the center of steel back 1, and the raised embedded inside of friction piece 3 of annulus is used for fixed friction
Body 3.
As shown in figure 4, the projection 4 on the front end face of steel back 1 inside embedded friction piece 3 includes strip bulge, strip bulge
One or the setting multiple being parallel to each other can be set, and the inside of strip bulge insertion friction piece 3 is used for fixed friction body 3.
