Description

Technical Field

[0001] The utility model relates to the technical field of disc brake pads, in particular to a disc brake pad. Background Art

[0002] At present, the disc brake pad is mainly composed of a steel sheet and a friction material layer formed by high-temperature pressing. During the braking process of an automobile, the friction material layer and the brake disc rub against each other to generate a force for braking the automobile. Since the brake pad is an essential part of the automobile, it is necessary to optimize the structure of the brake pad.

[0003] For example, a disc brake pad is disclosed in the Chinese utility model patent with the publication number CN219954038U. In the above prior art, although the device has the beneficial effects of being convenient for detecting its own temperature and the thickness of the friction layer, during the driving process of the automobile, dust particles and fine debris will enter between the brake disc and the brake pad. When the automobile brakes, the dust particles and fine debris will be clamped, causing noise during braking. This is because the surfaces of the brake pad and the brake disc are not clean, and the dust particles and fine debris rub against the surface of the brake disc. The noise during braking not only affects the driving experience, but also the dust particles and fine debris that cause the noise will increase the wear of the brake pad and the brake disc, resulting in a reduction in the service life of the brake disc and the brake pad. Therefore, it is necessary to design a disc brake pad that can clean the surface of the brake disc during braking. Summary of the Utility Model

[0004] To solve the technical problem that dust particles and fine debris will increase the wear of the brake disc and the brake pad during braking, the utility model provides a disc brake pad.

[0005] The utility model is realized by adopting the following technical scheme: A disc brake pad includes a brake pad and a friction block fixedly installed on one side of the brake pad. Cleaning components for rolling and cleaning the brake disc during vehicle braking are arranged on both sides of the brake pad. Rotating components for rotating the cleaning components are arranged on one side of the two cleaning components, and pushing components for closely fitting the cleaning components with the brake disc during braking are arranged on the other side of the two cleaning components. The cleaning component includes a mounting plate arranged on one side of the brake pad, a first rotating shaft rotatably installed on the mounting plate, and a cleaning roller fixedly sleeved on the first rotating shaft.

[0006] Through the above technical scheme, during the braking of the automobile, the pushing component will make the cleaning component contact the brake disc first, thereby cleaning the dust particles and fine debris on the brake disc to a certain extent and reducing the friction between the brake disc and the friction block.

[0007] As a further improvement of the above scheme, the mounting plate is arranged in a "C" shape.

[0008] Through the above technical solution, the first rotating shaft can be rotatably installed in the groove of the mounting plate.

[0009] As a further improvement of the above scheme, the rotating assembly includes two limit plates fixedly installed on one side of the brake pad, a second rotating shaft rotatably installed between the two limit plates, and a connecting plate fixedly sleeved on the second rotating shaft, and one side of the connecting plate is fixedly installed on one side of the mounting plate.

[0010] Through the above technical solution, the connecting plate cooperates with the second rotating shaft to allow the cleaning roller to move, thereby cleaning the surface of the brake disc.

[0011] As a further improvement of the above scheme, the pushing assembly includes a limiting plate fixedly installed on one side of the brake pad and having a sliding groove, a pushing rod slidably set inside the sliding groove, and a pushing spring sleeved on the pushing rod, one end of the pushing spring is in contact with the limiting plate.

[0012] Through the above technical solution, the push spring pushes the push rod, so that the cleaning roller can always be in close contact with the surface of the brake disc.

[0013] As a further improvement of the above solution, two connecting blocks are fixedly installed on one side of the connecting plate, a third rotating shaft is rotatably installed between the two connecting blocks, and one end of the push rod is rotatably matched with the third rotating shaft.

[0014] Through the above technical solution, the rotation of the connecting plate will not affect the pushing effect of the pushing rod.

[0015] As a further improvement of the above solution, a first limiting plate is fixedly sleeved on the push rod, a second limiting plate is fixedly mounted on one end of the push rod, and one side of the first limiting plate is fixedly mounted to the push spring.

[0016] Through the above technical solution, the expansion of the push spring will allow the push rod to continuously push the connecting plate, thereby allowing the cleaning roller to closely adhere to the surface of the brake disc for cleaning.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a cleaning component, a rotating component and a pushing component. When the car brakes, the brake pad drives the pushing component and the rotating component to move toward the brake disc, and the pushing component allows the cleaning component to contact the surface of the brake disc first. The contact between the cleaning component and the brake disc will clean the dust particles and fine debris on the surface of the brake disc to a certain extent, and the vibration caused by braking will also cause the dust particles and fine debris that become loose after contacting the cleaning component to fall off. This arrangement can not only clean the surface of the brake disc and reduce the wear caused by dust particles and fine debris, but also reduce the brake noise of the brake disc caused by dust particles and fine debris.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3, A disc brake pad of this embodiment includes a brake pad 1 and a friction block 2 fixedly installed on one side of the brake pad 1. Cleaning components for rolling cleaning the brake disc during vehicle braking are provided on both sides of the brake pad 1. Rotating components for rotating the cleaning components are provided on one side of the two cleaning components, and pushing components for closely fitting the cleaning components with the brake disc during braking are provided on the other side of the two cleaning components. The cleaning component includes a mounting plate 301 provided on one side of the brake pad 1, a first rotating shaft 302 rotatably installed on the mounting plate 301, and a cleaning roller 303 fixedly sleeved on the first rotating shaft 302. The mounting plate 301 is arranged in a "C" shape. When the vehicle brakes, the pushing component will make the cleaning component contact the brake disc first, thereby cleaning the dust particles and fine debris on the brake disc to a certain extent and reducing the friction between the brake disc and the friction block 2.

[0026] Combined with Figure 1 and Figure 2 , the rotating component includes two limiting plates 401 fixedly installed on one side of the brake pad 1, a second rotating shaft 402 rotatably installed between the two limiting plates 401, and a connecting plate 403 fixedly sleeved on the second rotating shaft 402. One side of the connecting plate 403 is fixedly installed with one side of the mounting plate 301. The connecting plate 403 and the second rotating shaft 402 can make the cleaning roller 303 move, thereby cleaning the surface of the brake disc.

[0027] Combined with Figure 2 , the pushing component includes a limiting plate 501 fixedly installed on one side of the brake pad 1 and provided with a sliding groove, a pushing rod 502 slidably arranged inside the sliding groove, and a pushing spring 503 sleeved on the pushing rod 502. One end of the pushing spring 503 is in contact with the limiting plate 501. Two connecting blocks 6 are fixedly installed on one side of the connecting plate 403. A third rotating shaft 7 is rotatably installed between the two connecting blocks 6. One end of the pushing rod 502 is rotatably matched with the third rotating shaft 7. A first limiting disc 8 is fixedly sleeved on the pushing rod 502. One end of the pushing rod 502 is fixedly installed with a second limiting disc 9. One side of the first limiting disc 8 is fixedly installed with the pushing spring 503. The pushing spring 503 pushes the pushing rod 502, which can make the cleaning roller 303 always closely adhere to the surface of the brake disc.

[0028] The implementation principle of a disc brake pad in the embodiment of the present application is as follows: when the car brakes, the brake pad 1 will gradually approach the brake disc with the friction block 2, and the angle between the connecting plate 403 and the second rotating shaft 402 is set in advance, so that before the contact, the cleaning roller 303 will first contact the surface of the brake disc, and the cleaning roller 303 will be squeezed and pushed. At this time, the pushing spring 503 will push the first limiting plate 8, so that the pushing rod 502 pushes against the third rotating shaft 7, and finally the connecting plate 403 drives the mounting plate 301 and the cleaning roller 303 to move, so that the cleaning roller 303 always keeps in contact with the brake disc. The surface of the brake disc is in close contact with the cleaning roller 303, so that the dust particles and small debris on the contact position between the brake disc surface and the cleaning roller 303 will be squeezed by the cleaning roller 303, and some of them will be attracted to the cleaning roller 303 due to the static electricity of friction, and some of them will fall off due to the friction and vibration of the car brake, because the fit with the brake disc has become loose after being squeezed by the cleaning roller 303. This arrangement can not only clean the surface of the brake disc, reduce the wear caused by dust particles and small debris, and extend the service life of the brake disc, brake pad 1 and friction block 2, but also reduce the brake noise of the brake disc caused by dust particles and small debris.

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
