Crackle, friction facing failure is further resulted in, increase the probability of security incident generation；On the other hand, when a certain portion of frictional layer
Divide after reaching the limit of wear, it is necessary to change whole friction facing, cause the wasting of resources；
(2) frictional layer is divided into several parts or is made up of several variform fritters by groove, by by butterfly-type bullet
The problem of flotator of the compositions such as spring is connected on substrate, and this kind of friction facing radiates when can alleviate braking, it can also be individually replaced
Frictional layer, but do not consider that frictional layer wears the problem of different in substrate different parts, and the splicing between substrate and frictional layer
It is complicated, change cumbersome.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of friction facing, its thermal diffusivity
It is good, it is possible to achieve different parts contact brake disc in different time, reduce concentrated wear, and after friction facing wear out failure,
It can only change and mutually be changed between single frictional layer or frictional layer, convenient disassembly, reduce cost.
Technical scheme：In order to solve the above technical problems, a kind of friction facing of the present invention, including the first substrate, the second base
Piece and the 3rd substrate, the both sides of second substrate are extended with several swallow-tailed boss, the first substrate and the 3rd substrate

Substrate front is equipped with several grooves, places arc fixed block in groove, and arc fixed block is fixed on the by locking device
On one substrate, the second substrate and the 3rd substrate, frictional layer is bonded with arc fixed block, frictional layer is located at the first substrate, second
On the front of substrate and the 3rd substrate, second substrate back is provided with pressure sensor, first substrate, the second substrate
It is connected respectively with push-plate with the back side of the 3rd substrate.
Preferably, the groove is recessed triangle, the arc fixed block is shaped as what is be used cooperatively with groove
Recessed triangle.
Preferably, the angular bisector at three angles of the arc fixed block intersects respectively, angle is 120 °.
Preferably, being bonded with three frictional layers on an arc fixed block, frictional layer is hexagon.
Preferably, three tops of the arc fixed block are semicircle.
Preferably, the locking device is steady pin.
Beneficial effect：The friction facing of the present invention, has advantages below：
(1) due to friction facing substrate is divided into three parts, pass through dovetail groove between every part and connect positioning, the substrate back of the body
Mechanics sensor is installed in face, is reached middle part using three push rods and is first promoted, and the effect that both sides section retards compress, can effectively be solved
Certainly frictional layer abrasion it is uneven, both sides friction layer serious wear the problem of.
(2) because frictional layer is bonded on an arc fixed block using every three hexagon bodies, then by steady pin with
Substrate connects, self-assembling formation groove, have simple in construction, safe and reliable, chip removal convenience, rapid heat dissipation, contact area big, installation and
The advantages that convenient disassembly.
(3) due to using independent frictional layer and dismountable installation form, it is possible to achieve be only individually replaced concentrated wear
The frictional layer of failure, and all frictional layer shapes and sizes are identical, any part can be changed mutually, and reaching repetition makes
Effect, maintenance and replacement cost are not only reduced, and save resource environmental protection again.
