Abstract

The utility model relates to a big steel backing of lightweight reinforcing bond strength mainly solves the heavy demand that subtracts that current heavy truck, big bus brake block big steel backing produced because the heavy charge of energy saving and emission reduction meter needs to reduce the whole quality of brake block and the technical problem that the security performance requires height. The utility model discloses present plane stamping forming structure who is different from big steel backing is current, becomes concave type with friction material faying face punching press to one side punching press forms the arch at the steel backing concave, the arch is cylindrical, highly is not more than the whole thickness of steel backing. The utility model discloses simple structure can reduce the weight of brake block by a wide margin, satisfies heavy truck, big bus to the lightweight demand of automobile parts to can increase substantially the ability of the biggest shearing force that friction material and brake block steel backing faying face can bear and anti "fatigue failure", increase the life of brake block, guarantee driver and crew's safety, improve efficiency, practice thrift the cost.

Description

Large lightweight steel backing with enhanced bonding strength

Technical Field

The utility model belongs to the technical field of the automobile brake spare part, concretely relates to big steel backing of lightweight reinforcing bonding strength.

Background

The large steel backing of the brake pad is mainly used for fixing friction materials and facilitating installation on a brake system. The weight of brake pads for heavy trucks and buses is required to be light and the safety is required to be higher for automobile parts including brake pads. The existing brake block steel back is limited by the structure and has heavy weight, and the bonding process of the steel back and the friction material generally adopts welded mesh and pulling thorn, so that the processing cost is high, the fatigue resistance is poor, and the safety performance is low.

SUMMERY OF THE UTILITY MODEL

For the shortcoming and the not enough of solving above-mentioned background art, the utility model provides a big steel backing of brake block solves current brake block, and especially heavy truck, big bus require to the brake block lightweight to and the high security performance requirement.

In order to achieve the above object, the utility model provides a following technical scheme: the large steel backing of the brake pad is different from the structure that the existing large steel backing of the brake pad is formed by plane punch, the bonding surface of the steel backing plate and the friction material is punched to form a depressed area, the depressed area is punched and protruded on the concave surface, the preferable protruded part is cylindrical, and the friction material is bonded on the depressed area through hot pressing. Preferably, the sum of the heights of the convex and concave areas is not more than the whole thickness of the steel back plate.

Preferably, the protrusion is a cylindrical protrusion; the radius of the 1/4 cylindrical protrusion is not more than the height of the 3/4 cylindrical protrusion.

Further, the steel back plate and the friction material are both of fan-shaped structures.

Furthermore, both sides of steel backplate all are provided with the bodiness welding piece that thickness is 9mm 2mm, ensure that installation position thickness accords with current assembly requirement.

Further, the thickening welding block (4) is of an L type structure.

The utility model discloses a technological effect and advantage: brake block steel backing, replace 9mm thickness steel through the steel with 6mm thickness, the depressed area is stamped out, reduce the weight of steel backing by a wide margin, realize brake block mounting dimension requirement through welding bodiness welding piece, satisfy car especially heavy truck, the light-weighted requirement of big bus, and through stamping out a plurality of arch on steel backing depressed area, pass through the firm bonding of hot pressing process of friction material and have a plurality of bellied depressed area, make partly entering into the recess around the arch of friction material, fill up the recess, form the concave part and with the circular convex part that protruding shape matches, when friction material receives the shearing force, friction material transmits the shearing force for brake block steel backing plate arch of hanging down, because of protruding convex part is great with the area of contact of protruding recess, so the shearing force can more effective dispersion. The utility model discloses simple structure can increase substantially anti shear capacity and anti "fatigue failure" ability between friction material and the brake block steel backing faying face, has increased the security performance of brake block, has guaranteed navigating mate's safety, has improved efficiency, has practiced thrift the cost.
