Abstract
The utility model discloses a spot array type automobile disc type braking lining block back plate, which comprises a main body of the braking lining block back plate. Spot array metal convex lunges which are made by using mechanical processing are arranged on the main body of the braking lining block back plate, wherein the height of the spot array metal convex lunges can be 1 mm to 3 mm and the top of each of the spot array metal convex lunges is provided with a bent hook. When in use, the spot array metal convex lunges on the main body of the braking lining block back plate directly enter friction materials and engaging force is formed by convex lunge bent hooks and the friction materials. Shearing strength can be larger than or equal to 30N/mm< 2 >, and thus a plurality of times of the strength can be raised, which conforms to the braking requirements of middle and heavy automobiles and big passenger automobiles. The situations that the current disc type braking can not be applied to the braking of the middle and heavy automobiles and the big passenger automobiles are changed, and the probable situations of uneven bonding and inconsistent thickness using adhesive agent singly for bonding at present are avoided. After automobile braking is adopted to the disc type braking, the defects of a drum type braking heat fading phenomenon are overcome, and braking effect can be raised more than 10%.
Description
Technical field
The utility model relates in a kind of being mainly used in, heavy goods vehicle, the front and back brake pad assembly of motorbus, particularly a kind of some formation automobile disk-type braking pad backboard.
Background technique
The brake slipper backboard that adopts is flat at present, adopts glue bonding with combining of drag friction piece, hot setting.The deficiency that exists is: the bonding strength of brake pad and backboard is not high, and its shear strength is r 〉=3.8N/mm
2,, can only be used for the preceding braking of pony car at present because its shear strength is not high.Other all employing drum brake, poor radiation, the heat fade of drum brake are big, influence braking effect, and the Professional visitors is all seeking a kind of solution.
Summary of the invention
The purpose of this utility model is to provide a kind of join strength that improves backboard and brake pad for the deficiency that solves above-mentioned technology, alternative in, the disc type brake on the heavy goods vehicles, passenger vehicle or the some formation automobile disk-type braking pad backboard of drum brake.
In order to achieve the above object, a kind of some formation automobile disk-type braking pad backboard that the utility model is designed, it comprises the brake pad back plate body, is provided with the protruding thorn of dot matrix metal that adopts machining to make on the brake pad back plate body.The height of the protruding thorn of dot matrix metal can be at 1 to 3 millimeter, and the protruding thorn of dot matrix metal top is provided with crotch.Described crotch becomes 90 ° approximately.Vertically the spacing of the protruding thorn of adjacent two row dot matrix metals is in 5 millimeter, and adjacent crotch direction can be opposite, and the adjacent spacing of the protruding thorn of the dot matrix metal in the same row is in 10 millimeter, and the protruding thorn of dot matrix metal is laterally interlaced.The area of described brake pad back plate body is identical with brake pad.
The resulting a kind of some formation automobile disk-type braking pad backboard of the utility model, during use, the drag friction piece directly is compressed on the of the present utility model some formation automobile disk-type braking pad backboard, the protruding thorn of dot matrix metal on the brake pad back plate body enters in the friction material, protruding thorn crotch and friction material form engaging force, and its shear strength can reach 〉=30N/mm
2, intensity can improve several times, in meeting, heavy goods vehicles and motor bus brake request, changed present disc type brake can not be applied in, the situation of heavy type and motor bus braking.Because the protruding thorn of dot matrix metal is evenly distributed, avoided present single with bonding bonding inhomogeneous, the situation that variable thickness causes that may occur of binder, the parallelism of brake pad and backboard is better than the product that technique for sticking is produced greatly, thereby initial braking effect is improved.After disc type brake is adopted in car brakeing, overcome the shortcoming of drum brake heat fade phenomenon, braking effect can improve more than 10%.
