Detailed description of the invention
With reference to accompanying drawing, 1-3 is described further the utility model.
A kind of drum brake brake block, comprises body 1. Body 1 comprises internal layer 11 and skin 12, and wherein internal layer 11 is made by the relatively large material nickel-manganese of thermal conductivity factor, and outer 12 are made by the relatively little material dilval of thermal conductivity factor.
The left and right sides of internal layer 11 is provided with the first inclined-plane 2, and outer 12 the left and right sides is provided with the second inclined-plane 3. One end butt on the one end on the first inclined-plane 2 and the second inclined-plane 3. The first inclined-plane 2 and the second inclined-plane 3 are combined to form projection. Brake block is provided with the installing hole 4 that simultaneously runs through internal layer 11 and outer 12, for brake block being arranged on to the brake of automobile. Installing hole 4 comprises the first duct 41, the second duct 42 and the connecting portion 43 that is connected the first duct 41 and the second duct 42. Wherein, the first duct 41 is positioned at internal layer 11, the second ducts 42 and is positioned at skin 12, and the diameter in the first duct 41 is less than the second duct 42. Connecting portion 43 be shaped as funnel-form. The size that installing hole 4 is concrete and number are adjusted according to the brake of different automobiles. On brake block, be also provided with the louvre 5 that runs through outer 12, for accelerate the heat radiation of brake block after automobile brake.

Increase the distribution density of abrasive particle and can be 1/cm2,5/cm2,10/cm2. Preferably, the distribution density of increasing abrasive particle is 5/cm2. Because the distribution density of 1/cm2 is too small, coefficient of friction impact when internal layer 11 is contacted with nave boss is little, and the distribution density of 10/cm2 is excessive, cause the increasing abrasive particle arranging to be equivalent to just add one deck contact-making surface at the outer surface of internal layer 11, can cause on the contrary coefficient of friction to be less than 5/cm2, be 5/cm2 so consider the distribution density of selection increasing abrasive particle. The shape that increases abrasive particle can be cylindric, rectangular-shaped. Preferably, increase abrasive particle be shaped as cylindric. Because rectangular-shaped increasing abrasive particle easily causes the drift angle of cuboid to be connected to nave boss in contacting with nave boss, the loss that this easily causes increasing abrasive particle on the one hand, also causes wearing and tearing to nave boss on the other hand. According to the distribution density and the shape that increase abrasive particle, the cross section that increases abrasive particle is set to the circular section of 0.1cm2.
People in when brake, brake block contact nave boss frictional heat, because the thermal conductivity factor of internal layer 11 materials is greater than the thermal conductivity factor of outer 12 materials, so it is outer 12 that internal layer 11 brake block deformation meetings are greater than, institute so that brake block entirety curve inwardly, thereby further increase the friction between nave boss, from and make brake block produce further bending trend, and due to nave boss butt, so cause the frictional force between brake block and nave boss more to increase, improve the efficiency of brake block. So in case of emergency, in the time that people use identical strength to go to operate brake block, this drum brake brake block has sensitiveer braking effect, reduces braking distance, improve security. In the ordinary course of things, in the time that people use identical strength to go to operate brake block, brake required time shorten, the muscle power that people consume also reduces thereupon.
Utilize the both sides of brake block to produce cambered outwards shape, thereby in the time that two brake block butts are combined, middle meeting produces space, the chip that facilitates nave boss and brake block contact friction to produce can flow out in time from space, avoids staying on 11 of internal layers causing brake block to contact the inhomogeneous rotating effect that affects with internal layer 11.
