Abstract
One kind brake backboard, it includes backboard, boss, groove；Boss and backboard integrative-structure, are cast, groove is located at boss side surfaces using spheroidal graphite cast-iron.Boss circular arc line of active force resultant direction suffered by is evenly arranged, concentric arc trajectory arrangement of the groove of boss side surfaces along circular arc line, powder metallurgy frictional layer forms active force under frictional force effect to boss during brake, each boss can equably share active force, make backboard uniform force, the groove design of boss side surfaces ensure that powder metallurgy frictional layer can be fully combined together after sintering curing with backboard, it is therefore prevented that the situation that frictional layer peels off during stress occurs.
Description
Technical field
The present invention relates to vehicle tool, more particularly to a kind of brake backboard.
Background technology
Brake backboard be braking automobile strength member, be powder metallurgy frictional layer attachment basal layer, present brake
Backboard one kind is that the adhesion effect of wire netting enhancing powder metallurgy frictional layer is welded on low-carbon steel backing plate, and one kind is spheroidal graphite in addition
Ironcasting, is disposed with boss thereon in certain area, purpose is also the attachment for strengthening powder metallurgy frictional layer on brake backboard
Power, but two class backboards do not consider the direction of frictional layer friction during brake, fail uniformly to share friction
On backboard, simultaneously because backboard is different from the performance of expanding with heat and contract with cold of powder metallurgy frictional layer, and because boss is laid out, side can not
Groove is processed, frictional layer is it is possible that situation about peeling off, attachment are not firm enough.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, there is provided one kind brake backboard.
The present invention is achieved through the following technical solutions：
One kind brake backboard, it includes backboard, boss, groove；Boss and backboard integrative-structure, are cast using spheroidal graphite cast-iron
Make, groove is located at boss side surfaces；
It is characterized in that above-mentioned brake backboard, powder metallurgy frictional layer is formed under frictional force effect to boss during brake
Active force, the circular arc line that resultant direction of the boss along the active force is formed are evenly arranged, and the grooves of boss side surfaces is along circular arc line
Concentric arc trajectory arranges that groove is shaped with form cutter along the milling of concentric arc trajectory after casting.
The beneficial effects of the invention are as follows：Powder metallurgy frictional layer is acted on boss formation under frictional force effect during brake
Power, the circular arc line that resultant direction of the boss along the active force is formed are evenly arranged, and each boss can equably share active force,
Ensure backboard uniform force, the groove design of boss side surfaces ensure that powder metallurgy frictional layer can fill after sintering curing with backboard
Divide and be combined together, it is therefore prevented that the situation that frictional layer peels off during stress occurs.

Fig. 2 is attaching powder metallurgy frictional layer schematic diagram of the present invention；
Fig. 3 is boss stress of the present invention and groove milling path schematic diagram；
Fig. 4 is the single boss stress diagram of the present invention.
In figure, backboard 1, boss 2, groove 3, powder metallurgy frictional layer 4
Embodiment
As shown in Figure 1,2,3, 4, a kind of brake backboard, it includes backboard 1, boss 2, groove 3；Boss is integrated with backboard
Structure, cast using spheroidal graphite cast-iron, groove is located at boss side surfaces；
It is characterized in that above-mentioned brake backboard, during brake powder metallurgy frictional layer 4 under frictional force effect to the shape of boss 2
Into active force f, the circular arc line that make a concerted effort F direction of the boss 2 along the active force is formed is evenly arranged, and the groove 3 of the side of boss 2 is along circle
The concentric arc trajectory X arrangements of camber line, groove 3 are shaped with form cutter along concentric arc trajectory X millings after casting.
The present invention the course of work be：Active force f can be formed during powder metallurgy 4 stress of frictional layer on boss 2, due to convex
The circular arc line that make a concerted effort F direction of the platform 2 along active force f is formed is evenly arranged, and each boss 2 on same circular arc line can be uniform
Born power is shared, and size is F with joint efforts, so layout makes the whole uniform force of backboard 1, simultaneously because the side of boss 2
Groove 3 along concentric arc trajectory X arrange, facilitate milling to shape, while ensure that powder metallurgy frictional layer 4 after sintering can
It is completely combined with backboard 1, is unlikely to peel off during stress.
Claims (2)
1. one kind brake backboard, it is characterised in that：Including backboard, boss, groove；Boss and backboard integrative-structure, using spheroidal graphite
Iron casting, groove are located at boss side surfaces.
A kind of 2. brake backboard as claimed in claim 1, it is characterised in that：Described brake backboard, powder metallurgy during brake
Frictional layer forms active force under frictional force effect to boss, and the circular arc line that resultant direction of the boss along the active force is formed is uniform
Arrangement, the concentric arc trajectory arrangement of the grooves of boss side surfaces along circular arc line, groove is after casting with form cutter along concentric arc
Trajectory milling shapes.
