Description

Technical Field

[0001] The utility model relates to the technical field of brakes, in particular to a brake pad steel back with good wear resistance. Background Art

[0002] The brake pad steel back is an important part of the brake system. The brake pad steel back can ensure that the brake system is stable and reliable during braking, while reducing wear and extending the life of components, thereby improving driving safety and overall performance.

[0003] After searching, the Chinese patent announcement number: CN201651125U discloses a brake pad steel back with a simple processing method and the ability to improve the adhesion strength of the brake pad friction substrate. It is mainly composed of a steel back body, a casting hole and a thrust block. The thrust block is in the shape of a strip, with a height of 4mm, a length of 20mm and a width of 3mm. The thrust blocks are distributed on the two sides of the front of the steel back body, one on the left and one on the right. The protruding thrust blocks are cast together with the steel back during the manufacturing of the steel back.

[0004] Since the above technology has two friction substrate thrust blocks on the front side of the steel back, the bonding strength of the entire friction substrate is increased and loosening and falling off will not occur. However, the above technology does not improve the heat resistance of the steel back, resulting in overheating of the steel back and reduced braking performance when used for a long time. Therefore, a brake pad steel back with good wear resistance is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a brake pad steel back with good wear resistance, aiming to improve the problem in the prior art that the brake pad steel back overheats and causes the braking performance to decrease when the brake pad steel back is used for a long time.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a brake pad steel back with good wear resistance, including a steel back plate, two heat-resistant layers are fixedly connected inside the steel back plate, the two heat-resistant layers are fixedly connected to the opposite sides with a sound insulation layer, the two sound insulation layers are fixedly connected to the opposite sides with a reinforcement layer, the bottom of the steel back plate is fixedly connected to an anti-corrosion layer, and a wear-resistant component is arranged on the side of the steel back plate and the anti-corrosion layer away from each other.

[0007] Furthermore, the wear-resistant component includes two wear-resistant coatings, and the two wear-resistant coatings are respectively fixedly connected to the steel back plate and the side away from the anti-corrosion layer.

[0008] Furthermore, two mounting holes are provided inside the steel back plate, the heat-resistant layer, the sound insulation layer, the reinforcement layer and the anti-corrosion layer.

[0009] Furthermore, a plurality of protrusions are arranged on the top of the steel back plate.

[0010] Furthermore, the material of the heat-resistant layer is chromium-molybdenum alloy.

[0011] Furthermore, the material of the sound insulation layer is ceramic fiber.

[0012] Furthermore, the reinforcement layer and the anti-corrosion layer are both made of stainless steel.

[0013] Furthermore, the wear-resistant coating is a carburized coating.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the heat resistance, sound insulation and self-strength of the steel back plate are significantly improved through the mutual cooperation among the steel back plate, the heat-resistant layer, the sound insulation layer, the reinforcement layer and the anti-corrosion layer, so that when the steel back plate is used at high intensity, the influence of heat on the braking performance is reduced, and the noise during braking can be reduced.

[0016] 2. In the present invention, by providing a wear-resistant coating at both ends of the steel back plate, the surface of the steel back plate has beneficial wear resistance, which can effectively reduce the wear of the steel back plate and increase the service life of the steel back plate.
