[0020] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0021] Example 1 See also Figures 1 to 10 In an embodiment of the present invention, a wear-resistant brake pad suitable for mountain roads includes a steel back substrate 1, a fixing box 3 is fixedly installed on the steel back substrate 1, a damping block 4 is locked and installed inside the fixing box 3 through a fixing mechanism arranged on the inner wall of the fixing box 3, a friction component is arranged on the upper end of the damping block 4, a pressing mechanism is arranged at a position corresponding to the fixing mechanism on the upper side of the inner wall of the fixing box 3, a convex block 25 is further arranged on the side wall of the damping block 4, an unlocking mechanism for unlocking the fixing mechanism is arranged inside the convex block 25, and the unlocking mechanism and the pressing mechanism are mutually In coordination with the setting, a shock absorbing groove 32 is also provided at the bottom of the shock absorbing block 4, and an active magnetic block 30 is installed inside the shock absorbing groove 32. A fixed magnetic block 13 is also installed at the corresponding position of the steel back substrate 1 and the active magnetic block 30. The polarities of the corresponding surfaces of the fixed magnetic block 13 and the active magnetic block 30 are opposite, so that a repulsive force can be generated between the fixed magnetic block 13 and the active magnetic block 30, thereby further ensuring the shock absorbing effect of the shock absorbing block 4 inside the fixed box 3. A heat dissipation mechanism for dissipating heat from the friction component is also provided on the shock absorbing block 4.

[0022] In order to realize the installation and fixation of the entire brake pad on the brake system, the steel back substrate 1 is symmetrically provided with installation grooves 2 .

[0023] In addition, in one case of this embodiment, the friction assembly includes a plurality of friction blocks 5 fixed on the upper surface of the damping block 4, and a plurality of chip removal grooves 23 are provided on the upper surface of the friction block 5 to achieve effective discharge of the debris generated by the friction block 5 during friction, while also taking into account the heat dissipation of the friction block 5. Adhesion blocks 11 are also installed in the alternating matching area between the upper surface of the damping block 4 and the friction block 5, and a metal block 6 is fixedly installed on the adhesion block 11. By providing the metal block 6, not only can a certain braking purpose be achieved, but also heat can be taken out, further ensuring the braking service life of the friction block 5.

[0024] In addition, in order to ensure the heat dissipation performance of the entire friction assembly, in this embodiment, the heat dissipation mechanism includes a heat dissipation elbow 7 arranged on the upper surface of the damping block 4, the heat dissipation elbow 7 is arranged in a bent manner between the metal block 6 and the friction block 5, and fixed straight pipes 10 are also installed at both ends of the heat dissipation elbow 7, and the fixed straight pipe 10 is installed on the fixed box 3 through a fixed card 9.

When working, using the principle of air cooling and heat dissipation, cold air enters the fixed straight pipe 10 through the top air nozzle 8, and then under the action of the heat dissipation elbow 7, the friction block 5 and the metal block 6 are heat dissipated.

[0025] In the preferred case of this embodiment, the fixing mechanism includes a locking straight groove 16 arranged at the lower side of the inner wall of the fixing box 3, a plurality of locking springs 17 are vertically installed inside the locking straight groove 16, a locking wedge 15 is fixedly installed at one end of the locking spring 17 away from the locking straight groove 16, and the locking wedge 15 is locked and matched with the locking wedge grooves 12 arranged at the lower side of both ends of the shock absorbing block 4. By means of the mutual locking and matching of the locking wedge 15 and the locking wedge groove 12, the shock absorbing block 4 can be detachably installed inside the fixing box 3, and finally the reliability of the entire brake pad is ensured.

[0026] At the same time, in order to ensure that the shock-absorbing block 4 can be quickly installed inside the fixed box 3, in this embodiment, the pressing mechanism includes a pressing groove 18 provided on the inner wall of the fixed box 3, a plurality of pressing springs 19 are fixedly installed in the vertical direction inside the pressing groove 18, a pressing block 20 is fixedly installed on the upper end of the pressing spring 19, a pressing rod 21 is fixedly installed on the side wall of the pressing block 20, the pressing rod 21 is an L-shaped rod structure, a pressing ball 22 is fixedly installed at the bottom of the pressing rod 21, and the pressing ball 22 contacts and cooperates with the upper end wedge surface of the locking wedge 15. By pressing the pressing rod 21 downward, the pressing ball 22 contacts and contacts with the wedge surface of the locking wedge 15, and then the locking wedge 15 moves toward the direction close to the locking straight groove 16, and finally the shock-absorbing block 4 can be better inserted downward into the fixed box 3.

[0027] In one case of this embodiment, the unlocking mechanism includes an unlocking groove 33 arranged inside the protrusion 25, an unlocking shaft 27 is slidably installed in the vertical direction inside the unlocking groove 33, an unlocking plate 28 is fixedly installed at the bottom of the unlocking shaft 27 through the unlocking groove 33, and the unlocking plate 28 contacts and cooperates with the lower pressing rod 21, and an unlocking block 29 is fixedly installed on the upper end of the unlocking shaft 27, and the unlocking block 29 is slidably arranged inside the unlocking groove 33, and an unlocking spring 26 is sleeved and installed outside the unlocking shaft 27 between the unlocking block 29 and the bottom of the unlocking groove 33. When the unlocking action of the locking mechanism needs to be realized, that is, when the damping block 4 is pulled out of the fixed box 3, the unlocking block 29 is pushed downward, and then, with the cooperation of the unlocking shaft 27, the unlocking plate 28 is pushed downward against the upper end surface of the lower pressing rod 21, and then, with the overall cooperation of the lower pressing mechanism, the overall unlocking action of the unlocking mechanism is realized, and the entire unlocking process is fast and convenient, which is worthy of popularization and use.

[0028] In addition, in order to effectively reduce the noise of the entire brake pad during braking, in this embodiment, a sound-absorbing cotton layer 14 is also installed in the non-fixed magnetic block 13 area on the steel back substrate 1 located on the bottom side of the fixed box 3.

[0029] Example 2 The present invention also provides another embodiment, which is different from the above embodiment in that a circle of shock-absorbing rubber plate 31 is fixedly installed on the outer area of ​​the movable magnetic block 30 at the bottom of the shock-absorbing block 4. The set shock-absorbing rubber plate 31 further ensures that the fixed magnetic block 13 and the movable magnetic block 30 will not directly collide and contact during the mutual repulsion and shock-absorbing process to cause damage to the magnetic blocks.

[0030] To sum up, during assembly, the installation of the shock absorbing block 4 inside the fixed box 3 is achieved through the pressing mechanism. When the friction component needs to be replaced, the unlocking mechanism and the pressing mechanism cooperate with each other to achieve the disassembly and separation of the shock absorbing block 4. During the entire working process of the brake pad, the friction component is cooled and dissipated by the heat dissipation mechanism to ensure the service life of the entire brake pad. At the same time, with the cooperation between the fixed magnetic block 13 and the movable magnetic block 30, the shock absorbing purpose of the brake pad is achieved, further ensuring the performance of the brake pad.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
