Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to a high-heat-conductivity and wear-resistant brake pad. Background Art

[0002] Brake pads are key components in a car's braking system, and their condition is directly related to the vehicle's driving safety. Generally speaking, the replacement cycle of brake pads depends on many factors, including the vehicle's mileage, driving habits, and the actual wear of the brake pads.

[0003] The material and structure of brake pads have a great influence on their performance and service life. Different types of brake pads have their own characteristics and applicable scope. The existing brake pads are easy to install and replace.

[0004] However, the currently available brake pads do not have a heat-insulating and wear-resistant structure, which leads to overheating and rapid wear under long-term use, seriously affecting the service life of the brake pads and failing to meet long-term use requirements. Therefore, a high thermal conductivity and wear-resistant brake pad is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a high thermal conductivity and wear-resistant brake pad with the advantages of heat insulation and wear resistance. It solves the problem that the current brake pads do not have a heat insulation and wear-resistant structure, which leads to overheating and rapid wear under long-term use, seriously affecting the service life of the brake pads and cannot meet the long-term use requirements.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high heat-conducting and wear-resistant brake pad, comprising a steel plate and a stop block, wherein the exterior of the steel plate is provided with a heat-insulating and wear-resistant structure;

[0007] The heat-insulating and wear-resistant structure includes a titanium alloy plate fixedly connected to the back of a steel plate, a friction block and a graphite sheet are bonded to the front of the steel plate, heat dissipation holes are provided on the outer surfaces of the titanium alloy plate and the steel plate, an asbestos layer and a ceramic layer are provided inside the friction block, and the outer surfaces of the steel plate and the titanium alloy plate are thermally sprayed with a wear-resistant coating.

[0008] Furthermore, a positioning block is fixedly connected to the back of the titanium alloy plate, threaded holes are provided on the outer surfaces of the positioning block and the stop block, and positioning screws are arranged around the top of the stop block.

[0009] Furthermore, the positioning screw is threadedly connected to the threaded hole, and the stop block is provided with a positioning groove.

[0010] Furthermore, the steel plate and the titanium alloy plate are consistent in size and thickness, and mounting holes are provided at the upper ends of the steel plate and the titanium alloy plate.

[0011] Furthermore, there are two heat dissipation holes, which are relatively distributed on the left and right sides of the friction block.

[0012] Furthermore, the asbestos layer is bonded and fixed to the ceramic layer, the number of the asbestos layer and the number of the ceramic layer are both three, the top end of the friction block is the asbestos layer, and the bottom end of the friction block is the ceramic layer.

[0013] Furthermore, the number of the graphite sheets and the number of the friction blocks are both two, and the two graphite sheets are distributed between the two friction blocks.

[0014] Compared with the prior art, the utility model provides a high thermal conductivity and wear-resistant brake pad, which has the following

[0015] Beneficial effects:

[0016] 1. The high thermal conductivity and wear-resistant brake pad is provided with a heat-insulating and wear-resistant structure. When in use, the heat generated by the friction between the brake pad and the brake disc will first be simply isolated by the ceramic layer, thereby reducing its conduction speed. Then, the heat gradually conducted to the steel plate will be partially absorbed by the graphite sheet and then dissipated outward through the heat dissipation holes. During this period, most of the heat conducted to the steel plate will be isolated by the titanium alloy plate with low thermal conductivity, thereby avoiding overheating of the brake pad. In addition, the wear-resistant coating and the three-layer asbestos layer and the ceramic layer are used in combination to improve the wear resistance of the steel plate, the titanium alloy plate and the friction block, which can effectively avoid the occurrence of brake pad abrasion and excessive wear, thereby increasing the service life of the brake pad.

[0017] 2. The high thermal conductivity and wear-resistant brake pad is equipped with a stop block, a positioning block, a threaded hole, a positioning screw and a positioning groove. When in use, the staff only needs to tighten the positioning screw into the threaded hole to install the stop block on the back of the brake pad. At this time, the positioning groove can facilitate the staff to position the piston of the brake caliper here, so that the piston can push the brake pad outward, thereby avoiding the occurrence of pushing offset.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] See also Figure 1-4 In this embodiment, a high heat-conductivity and wear-resistant brake pad includes a steel plate 1 and a stopper 4, and a heat-insulating and wear-resistant structure is provided on the outside of the steel plate 1;

[0027] The heat-insulating and wear-resistant structure includes a titanium alloy plate 12 fixedly connected to the back of a steel plate 1, a friction block 2 and a graphite sheet 3 are bonded to the front of the steel plate 1, heat dissipation holes 5 are provided on the outer surfaces of the titanium alloy plate 12 and the steel plate 1, an asbestos layer 201 and a ceramic layer 202 are arranged inside the friction block 2, and the outer surfaces of the steel plate 1 and the titanium alloy plate 12 are thermally sprayed with a wear-resistant coating 6. When in use, the heat generated by the friction between the brake pad and the brake disc will first be simply isolated by the ceramic layer 202, thereby reducing its conduction speed, and then the heat gradually conducted to the steel plate 1 will be partially absorbed by the graphite sheet 3, and then dissipated outward through the heat dissipation holes 5.

[0028] During this period, most of the heat conducted to the steel plate 1 will be isolated by the titanium alloy plate 12 with low thermal conductivity, thereby avoiding overheating of the brake pad. In addition, the wear resistance of the steel plate 1, the titanium alloy plate 12 and the friction block 2 is improved through the cooperation of the wear-resistant coating 6 and the three-layer asbestos layer 201 and the ceramic layer 202, which can effectively avoid the occurrence of brake pad abrasion and excessive wear, thereby increasing the service life of the brake pad.

[0029] The steel plate 1 and the titanium alloy plate 12 are consistent in size and thickness, and mounting holes 7 are provided at the upper ends of the steel plate 1 and the titanium alloy plate 12 . There are two heat dissipation holes 5 , which are relatively distributed on the left and right sides of the friction block 2 .

[0030] At the same time, the asbestos layer 201 and the ceramic layer 202 are bonded and fixed, and the number of the asbestos layer 201 and the number of the ceramic layer 202 are three. The top of the friction block 2 is the asbestos layer 201, and the bottom of the friction block 2 is the ceramic layer 202.

[0031] It should be noted that the number of graphite sheets 3 and the number of friction blocks 2 are both two, and the two graphite sheets 3 are distributed between the two friction blocks 2. The graphite sheets 3 distributed between the two friction blocks 2 can directly absorb heat nearby.

[0032] Embodiment 2:

[0033] See also Figure 2 and Figure 5 On the basis of Example 1, a positioning block 8 is fixedly connected to the back of the titanium alloy plate 12, and threaded holes 9 are provided on the outer surfaces of the positioning block 8 and the stop block 4. Positioning screws 10 are arranged around the top of the stop block 4, and the positioning screws 10 are threadedly connected to the threaded holes 9. A positioning groove 11 is provided on the stop block 4. Through the cooperation of the stop block 4, the positioning block 8, the threaded hole 9, the positioning screws 10 and the positioning groove 11, when in use, the staff only needs to tighten the positioning screws 10 into the inside of the threaded hole 9 to install the stop block 4 on the back of the brake pad. At this time, the positioning groove 11 can facilitate the staff to position the piston of the brake caliper here, so that the piston can push the brake pad outward, thereby avoiding the occurrence of pushing offset.

[0034] The working principle of the above embodiment is:

[0035] When in use, the heat generated by the friction between the brake pad and the brake disc will first be simply isolated by the ceramic layer 202, thereby reducing its conduction speed. Then, the heat gradually conducted to the steel plate 1 will be partially absorbed by the graphite sheet 3 and then dissipated outward through the heat dissipation holes 5. During this period, the heat conducted to the steel plate 1 will be mostly isolated by the titanium alloy plate 12 with low thermal conductivity, thereby avoiding overheating of the brake pad. In addition, through the cooperation of the wear-resistant coating 6 and the asbestos layer 201 and the ceramic layer 202, which are three layers in number, the wear resistance of the steel plate 1, the titanium alloy plate 12 and the friction block 2 is improved, which can effectively avoid the occurrence of brake pad abrasion and excessive wear, thereby increasing the service life of the brake pad.
