Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Wherein identical components are presented with like reference characters.It should be noted that word used in the following description
Language "front", "rear", "left", "right", "up" and "down" refer to the direction in attached drawing, word " bottom surface " and " top surface ", "inner" and
"outside" refers respectively to the direction towards or away from geometric center of specific component.
A kind of wear brake pad, as shown in Figure 1, including the steel back 1 connecting with vehicle and rubbing for what is abutted with frictional disk
Substrate 2 is wiped, 1 upper end of steel back is welded with the lifting lug 11 connecting with vehicle, and lifting lug 11 offers connecting hole.2 hot pressing of friction substrate is solid
Due to 1 surface of steel back, steel back 1 is worn far from the end face of friction substrate 2 has penetrated four thermally conductive sheet 3(and sees Fig. 2), one end of thermally conductive sheet 3
In steel back 1 and insertion friction substrate 2, the other end is contacted with air.When brake block starts to work and generates frictional heat, benefit
With thermally conductive sheet 3 by the heat transfer in friction substrate 2 into air, later using air flowing by heat transfer, to make
The temperature of friction substrate 2 reduces, and reduces friction substrate 2 and is deformed because generating thermal expansion.It is increased simultaneously by thermally conductive sheet 3
Bonding strength between friction substrate 2 and steel back 1 reduces friction substrate 2 and is disconnected with steel back 1 and brake block is caused to be scrapped
The case where generation.
As shown in Figure 1, since distortion can be generated when friction substrate 2 generates thermal expansion, to influence the strong of friction substrate 2
Degree, influences the using effect of brake block.Therefore friction substrate 2 include four pieces be in rectangle friction plate 21, adjacent friction plate 21 it
Between there are gaps, and every piece of friction plate 21 is shown in Fig. 2 with one piece of thermally conductive sheet 3() be fixedly connected.It is heated and generates in friction plate 21
There is distensible space when expansion, so that friction plate 21 be made not generate distortion, brake block is made to keep stablizing.It simultaneously will friction
Piece 21 is disconnected from each other, increases the contact area with air, increases the speed of 2 heat loss of friction substrate.
As shown in Figure 1, the radiating rate of friction plate 21 in order to further increase, end face adjacent to each other between friction plate 21
Through there is several ventilation holes 211, ventilation hole 211 can run through thermally conductive sheet 3.During vehicle is advanced, air is from ventilation
The heat losses for making friction plate 21 are flowed through in hole 211, increase the speed of heat loss, reduce friction plate 21 because heat is swollen
Swollen and generation deformation.
As shown in Figure 1, in use due to brake block, friction plate 21 can generate abrasion and be adhered to have clast
The surface of friction plate 21 reduces the surface roughness of friction plate 21, influences the using effect of brake block.Therefore 21 table of friction plate
Face offers several chip spaces 212 in rectangle, and chip space 212 runs through the end face of friction plate 21.Chip space 212 is inclined to be set
It sets, is arranged in the side of vertical direction in 45 degree of angles with friction plate 21.By the way that the chip space 212 being obliquely installed is arranged, rubbing
When wiping disk and friction plate 21 and contacting, what chip will receive frictional disk application is parallel to the power of frictional disk rotation direction, to make to cut
Bits are easier to be discharged by chip space 212, so that the braking effect of brake block be made to keep stablizing, while utilizing chip space 212 into one
Step increases the contact area with air, increases the speed of the heat dissipation of friction plate 21.
As shown in Figure 1, since friction plate 21 will receive the power perpendicular to chip space 212 of frictional disk application at work,
Power to make the junction of brake block and vehicle be subject to increases, and influences the bonding strength of brake block and vehicle.Therefore adjacent to rub
Chip space 212 in pad 21 is vertical setting, thus the power that the frictional disk for being subject to adjacent friction plate 21 applies towards phase
Instead, so that the power being subject between friction plate 21 is offset each other, reduce the power that the junction of steel back 1 and vehicle is subject to, reduce brake
The probability that vehicle piece is connect with vehicle derailing increases the stability of brake block connection.
As shown in Figure 1, since stress is concentrated mainly on its four corners to friction plate 21 in use, to be directed at friction
The four corners of piece 21 are broken, and influence the use of brake block.Therefore the four corners of friction plate 21 offer lozenges 213,
The stress dispersion for being subject to friction plate 21 when in use by the way that lozenges 213 is arranged, thus be broken friction plate 21 will not,
Increase stability when brake block uses.
As shown in Figure 1, the bonding strength between friction plate 21 and steel back 1, steel back 1 are connected with friction in order to further increase
The end face of substrate 2 is welded with four support sleeves 12, and support sleeve 12, which is socketed with friction plate 21, to be cooperated, and support sleeve 12 and ventilation hole
There is gap between 211.The contact area between friction plate 21 and steel back 1 is increased by the way that support sleeve 12 is arranged, to increase
Bonding strength between friction plate 21 and steel back 1.
Working principle:
When work, the friction plate 21 of brake block is directly abutted with frictional disk, utilizes rubbing between frictional disk and friction plate 21
Wiping power makes vehicle braking.Friction plate 21 can be stained with the clast generated by friction during friction simultaneously, later clast
It takes down in the effect for the frictional force that frictional disk applies into chip space 212, later from chip space 212 under the action of frictional disk
Interior outflow, clast will not be adhered to 21 surface of friction plate and influence the roughness of friction plate 21.It is increased in the heat of friction plate 21
When, heat, to increase the speed of 21 temperature of friction plate reduction, is reduced into friction plate towards transmitting in air using thermally conductive sheet 3
21 because of the excessively high generation distortion of temperature.Simultaneously because braking is during vehicle is advanced, air can be flowed through out of air inlet, will
Heat in friction plate 21 is taken away, to further increase the lost speed of temperature.
