Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to a high-strength wear-resistant multi-layer composite material brake pad. Background Art

[0002] Brake pads, also called brake pads, are the most critical safety parts in the car's braking system. The quality of all braking effects is determined by the brake pads.

[0003] The existing patent document with publication number CN217440646U discloses a high-strength, wear-resistant, multi-layer composite brake pad. By setting a limit mechanism and cooperating with the friction matrix, when in use, the limit spring can resist the card block to be clamped into the empty groove. At this time, the card block cooperates with the empty groove, so that the limit pin fixes the friction matrix, thereby completing the installation of the friction block. At the same time, when the friction block needs to be replaced, the handle inside the accommodating groove is rotated to drive the limit pin to rotate, so that the inclined surface of the card block and the inclined surface of the empty groove conflict with each other. At this time, the card block compresses the limit spring to shrink into the perforation. At this time, the limit pin can be pulled out to disassemble the friction block, making the friction block easier to replace and saving material consumption. In addition, by setting the groove and the base block to be regular hexagonal, the friction block can be auxiliary fixed, thereby improving the installation stability of the friction block.

[0004] Although the above-mentioned high-strength, wear-resistant, multi-layer composite brake pad can solve the corresponding technical problems, its limit pin is inserted into the mounting hole in the groove. Therefore, when the brake pad is vibrated, the limit pin is prone to self-rotation. At the same time, the card block is only clamped in the corresponding empty groove by a limit spring. After long-term use, the elasticity of the limit spring will weaken, which will cause the card block to easily loosen, thereby reducing the installation stability of the friction block. For this reason, we propose a high-strength, wear-resistant, multi-layer composite brake pad. Utility Model Content

DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-Figure 3The embodiment of the utility model provides a high-strength wear-resistant multi-layer composite brake pad, comprising: a brake pad main body 1, a plurality of groups of regularly distributed friction blocks 2, a connector 3 for realizing a detachable connection between the brake pad main body 1 and the friction blocks 2, a limiting member 4 for limiting and a fixing member 5 for positioning, the friction blocks 2 are arranged on the front side of the brake pad main body 1, and each group of friction blocks 2 is provided with at least two, and the connector 3 is respectively provided between each group of friction blocks 2 and the brake pad main body 1, the limiting member 4 is arranged on the top of the brake pad main body 1, and the fixing member 5 is arranged between the brake pad main body 1 and the limiting member 4; the connector 3 includes a limiting strip 31 fixedly connected to the rear side of a corresponding group of friction blocks 2, and the front side of the brake pad main body 1 is provided with a limiting groove 32 adapted to the limiting strip 31.

[0025] It should be noted that the structure and working principle of the above-mentioned friction block 2 are consistent with the friction block in a high-strength, wear-resistant, multi-layer composite brake pad disclosed in the existing publication number CN217440646U, which is composed of a heat dissipation block, a heat conductive block, a high manganese steel wear-resistant block, a heat dissipation hole and a reinforcement block. During the friction process, the high heat can be discharged through the heat conductive block. At this time, rapid heat dissipation is achieved through the heat dissipation holes on the heat dissipation block, and due to the split design of the friction block, the gap between the friction blocks can also assist in rapid heat dissipation. It is a prior art, so it will not be described in detail in this technical solution.

[0026] Among them, the brake pad main body 1 includes a back plate 11, the front side of the back plate 11 contacts the friction block 2, both sides of the back plate 11 are integrally formed with lugs 12, the top of the back plate 11 is integrally formed with two symmetrical bosses 13, the lugs 12 and the bosses 13 are respectively provided with mounting holes 14, and the back plate 11 can be installed through the mounting holes 14 in conjunction with bolts.

[0027] The limiting groove 32 is provided on the front side of the back plate 11 , and the cross-sections of the limiting strip 31 and the limiting groove 32 are dovetail or T-shaped structures, which can prevent the limiting strip 31 from escaping from the inner cavity of the limiting groove 32 along the front-rear direction.

[0028] Among them, the limiting member 4 includes a baffle 41 movably arranged on the top of the back plate 11, and an arc-shaped portion 42 is respectively provided on both sides of the surface of the baffle 41. The arc-shaped portion 42 is arranged in a one-to-one correspondence with the convex column 13, and the arc-shaped portion 42 is sleeved on the surface of the corresponding convex column 13. The bottom of the baffle 41 contacts the top of the limiting strip 31. Through the coordinated use of the baffle 41 and the arc-shaped portion 42, the limiting strip 31 can be limited, and the limiting strip 31 can be limited to slide in the inner cavity of the limiting groove 32 along the length direction of the limiting strip 31, so that the friction block 2 can be stably installed on the front side of the back plate 11.

[0029] The bottom opening size of the arc portion 42 is smaller than the diameter of the boss 13, which can effectively limit the vertical movement of the limiter 4 on the top of the back plate 11, so that the baffle 41 and the arc portion 42 can only be placed horizontally on the top of the back plate 11 along the front-to-back direction.

[0030] Among them, the fixing part 5 includes a through hole 51 respectively opened on both sides of the surface of the baffle 41, and a screw hole 52 is opened on both sides of the top of the back plate 11. The through hole 51 and the screw hole 52 are arranged in a one-to-one correspondence. The inner cavity of the through hole 51 is penetrated by a screw 53. The bottom end of the screw 53 penetrates into the inner cavity of the corresponding screw hole 52 and is threadedly connected with it. Through the use of the through hole 51, the screw hole 52 and the screw 53, the horizontal movement of the limit member 4 at the top of the back plate 11 can be restricted, thereby playing a positioning role for the limit member 4.

[0031] Among them, a countersunk hole 54 connected to the top of the inner cavity of the through hole 51 is opened on the surface of the baffle 41, and the head of the screw 53 is placed in the inner cavity of the countersunk hole 54, which can effectively hide the head of the screw 53 so that it will not protrude from the surface of the baffle 41, thereby improving the overall aesthetics.

[0032] Among them, an identification area 6 is respectively provided at the top of the limit strip 31 and the top of the back plate 11, and the two identification areas 6 located at the front and back are arranged correspondingly, so that during the replacement operation, the corresponding limit strip 31 can be quickly inserted according to the identification on the identification area 6, avoiding the phenomenon of incorrect insertion of the limit strip 31, thereby further improving the replacement efficiency of the friction block 2.

[0033] The working principle of the utility model is as follows: when the friction block 2 is worn, the screw 53 is screwed out from the inner cavity of the screw hole 52 with the help of an auxiliary tool, and the limit piece 4 can be unlocked; then the stop bar 41 is moved horizontally in the front-rear direction, and the stop bar 41 drives the arc-shaped portion 42 to move synchronously until the stop bar 41 and the arc-shaped portion 42 are separated from the top of the back plate 11, and the connector 3 can be unlocked; at this time, the corresponding friction block 2 can be moved according to the wear area, so that the worn friction block 2 drives the limit strip 31 on its rear side to slide in the inner cavity of the corresponding limit groove 32, until the limit strip 31 moves out of the inner cavity of the limit groove 32, and the worn friction block 2 can be removed; then, the matching limit strip 31 and friction block 2 are selected according to the identification area 6, and the limit strip 31 is inserted into the inner cavity of the corresponding limit groove 32, and finally the limit piece 4 is fixed to the top of the back plate 11 by the fixing member 5, and the replacement operation of the friction block 2 can be completed.

[0034] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
