Description

Technical Field

[0001] This application relates to the technical field of brake discs, and in particular to a device for increasing the surface friction coefficient of brake discs. Background Technology

[0002] The main components of a disc brake include the brake disc, brake caliper, and brake pads. The brake pads are the friction material that the caliper piston pushes and presses against the brake disc. The brake caliper drives the brake pads and brake disc to work together to achieve deceleration.

[0003] When decelerating, the brake caliper moves the brake pads installed inside it, which clamp the brake disc, creating friction between them. This friction causes the brake disc to decelerate.

[0004] After prolonged use, the surface of the brake disc gradually becomes smooth due to friction, resulting in a decrease in its surface friction coefficient and affecting the brake disc's deceleration effect. Therefore, after a period of use, it is necessary to remove the brake disc and treat its surface. However, the entire disassembly and installation process is quite cumbersome and inconvenient to perform this treatment. Summary of the Invention

[0005] To facilitate the processing of brake discs, this application provides a device for increasing the surface friction coefficient of brake discs.

[0006] The device for increasing the surface friction coefficient of a brake disc provided in this application adopts the following technical solution:

[0007] A device for increasing the surface friction coefficient of a brake disc includes a brake disc body and a brake caliper that cooperates with the brake disc body. A brake pad is disposed inside the brake caliper. A mounting seat is mounted on the brake caliper. A central groove is formed on the mounting seat. The brake disc body extends into the central groove. A friction pad is disposed in the central groove. When the brake disc body rotates, the friction pad abuts against the side of the brake disc body to process the roughness of the surface of the brake disc body.

[0008] By adopting the above technical solution, the friction pad is installed on the mounting base. When the brake disc body needs to be processed, the mounting base is installed on the brake caliper, and the brake disc body is rotated at the same time. The friction surface of the friction pad is used to process the brake disc, thereby increasing the friction coefficient of the brake disc surface so as to process the brake disc body.

[0009] Optionally, a movable groove is provided through the mounting base at the position corresponding to the brake pad, and a movable plate is provided in the movable groove. The movable plate is slidably disposed in the direction toward the brake disc body, and the friction pad is disposed on the side of the movable plate away from the brake pad.

[0010] By adopting the above technical solution, the movable plate and brake pads are set up in a corresponding manner. In the initial state, the friction pads and the brake disc body are spaced apart so that the mounting base can be installed on the brake caliper. After installation, the brake caliper is operated to move the brake pads toward the brake disc body. The brake pads and the movable plate abut against each other, thereby moving the movable plate to adjust the position of the friction pads so that the friction pads and the brake disc body can cooperate to process the brake disc body.

[0011] Optionally, one side of the mounting base has an opening communicating with the movable slot, and the movable plate has an insertion slot on the side near the brake disc body. The insertion slot is located near the opening, and the movable plate has an insertion interface on the side near the opening. The insertion interface communicates with the insertion slot. The friction pad includes a mounting part and a friction part. The mounting part is inserted into the insertion slot through the insertion slot, and the friction part is located on the side of the mounting part near the brake disc body for processing the brake disc body.

[0012] By adopting the above technical solution, an insertion interface and opening are provided so that the friction pads can be installed or different friction pads can be replaced after the mounting bracket is installed on the brake caliper, so that friction pads with different diamond particle sizes can be replaced according to the different treatment needs of the brake disc.

[0013] Optionally, a sliding groove is provided on the inner wall of the movable groove, and a slider is provided on the movable plate. The slider is slidably disposed in the sliding groove, and a reset member is provided in the sliding groove. The reset member is connected to the slider, and the reset member is used to drive the movable plate to slide in a direction away from the brake disc body.

[0014] By adopting the above technical solution, a reset component is set to move the movable plate to the initial position. In the initial position, the friction pad and the brake disc are spaced apart, so that the position of the friction pad can be adjusted again or different friction pads can be easily replaced.

[0015] Optionally, the mounting base has a placement groove communicating with the movable groove, and an adjusting plate is provided in the placement groove. The adjusting plate is slidably disposed along a sliding direction perpendicular to the movable plate. The adjusting plate is disposed on the side of the movable plate away from the brake disc body. A guide slope is provided on the movable plate at a position corresponding to the adjusting plate. The adjusting plate and the guide slope abut against each other. The abutment of the adjusting plate and the guide slope at different positions is used to drive the movable plate to move in a direction toward the brake disc body. The mounting base is provided with a control device for adjusting the position of the adjusting plate.

[0016] By adopting the above technical solution, the control device drives the adjustment plate to move, and the adjustment plate moves to abut against different positions on the guide slope, thereby driving the movable plate to move and adjust the position of the friction pad, so as to achieve precise control of the distance between the friction pad and the brake disc body and to treat the surface roughness of the brake disc body.

[0017] Optionally, the mounting base is provided with an extension portion, which is located outside the brake caliper. An extension groove is formed in the extension portion. The control device includes a control lever, an intermediate component, and a control rod. The control rod is rotatably disposed within the mounting base and is disposed along the sliding direction of the adjusting plate. The control rod and the adjusting plate are threadedly connected. The end of the control rod extends into the extension groove. The control lever is rotatably disposed within the extension groove and its end extends outside the extension portion. The intermediate component is disposed within the extension groove for connecting the control lever and the control rod.

[0018] By adopting the above technical solution, the control lever is rotated, and the control lever drives the control lever to rotate through the intermediate part. The rotation of the control lever drives the adjustment plate to move through the threaded part, thereby adjusting the position of the adjustment plate. At the same time, the extension part is set outside the brake caliper to facilitate the operation of the control lever.

[0019] Optionally, a first gear is provided on the outside of the control lever, and the first gear is disposed in the extension groove. The intermediate component includes a worm, a worm wheel, a second gear, and a third gear. The second gear and the third gear are both rotatably disposed in the extension groove. The second gear meshes with both the first gear and the third gear. The worm wheel and the third gear are coaxially disposed. The worm rotates in the extension groove and meshes with the worm wheel. The worm and the control lever are coaxially connected.

[0020] By adopting the above technical solution, rotating the control lever drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the third gear to rotate, and the third gear drives the control lever to rotate through the second gear and the first gear, thereby adjusting the position of the adjustment plate.

[0021] Optionally, a mating surface is provided on one side of the adjusting plate and the guide slope, and the mating surface and the guide slope abut against each other.

[0022] By adopting the above technical solution, a mating surface and a guide slope are set to match, increasing the contact area between the adjusting plate and the guide slope, thereby improving the stability of the fit between the adjusting plate and the movable plate.

[0023] Optionally, the opening is located on the side of the mounting base opposite to the rotation direction of the brake disc body.

[0024] By adopting the above technical solution, the opening is set on this side of the mounting base, so that when the brake disc body rotates, it drives the friction pad to move in the direction towards the inside of the insertion groove, reducing the phenomenon of the friction pad disengaging from the insertion groove and improving the stability of the fit between the friction pad and the insertion groove.

[0025] Optionally, the mounting base is provided with a retaining plate, the retaining plate has bolt holes, and bolts are provided in the bolt holes. The end of the bolts and the side of the brake caliper are used to install the mounting base on the brake caliper.

[0026] By adopting the above technical solution, a clamping plate and bolts are set to fix the mounting base on the brake caliper, thereby improving the stability of the friction pad when processing the brake disc body.

[0027] In summary, this application includes the following beneficial technical effects: the friction pad is mounted on the movable plate, and when the brake disc needs to be processed, the mounting base is rotated onto the brake caliper, and then the position of the adjusting plate is adjusted so that the friction pad and the brake disc body abut against each other, so as to process the brake disc body.

[0036] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0037] This application discloses a device for increasing the surface friction coefficient of a brake disc. (Refer to...) Figure 1 and Figure 2 The device for increasing the surface friction coefficient of the brake disc includes a brake disc body 1 and a brake caliper 2 that cooperates with the brake disc body 1. A brake pad 21 is provided in the brake caliper 2. The brake pad 21 is arranged correspondingly to the side of the brake disc body 1. The brake caliper 2 drives the brake pad 21 to abut against the side of the brake disc body 1, clamping the brake disc body 1 to achieve deceleration.

[0038] Reference Figure 2 and Figure 3 A mounting base 3 is installed on the brake caliper 2. A central groove 31 is formed on the mounting base 3. The edge of the brake disc body 1 extends into the central groove 31. A friction pad 4 is provided on the inner wall of the central groove 31, corresponding to the side surface of the brake disc body 1. The surface of the friction pad 4 is electroplated with diamond particles to increase its surface friction. When processing is required for the brake disc body 1, the mounting base 3 is installed on the brake caliper 2, and the brake disc body 1 is rotated. The friction surface of the friction pad 4 abuts against the side surface of the brake disc body 1, processing its surface. The diamond particles on the surface of the friction pad 4 create scratches on the surface of the brake disc body 1, increasing the coefficient of friction.

[0039] Reference Figure 1 and Figure 2 A retaining plate 32 is provided on the mounting base 3, which is secured to the brake caliper 2. A bolt hole 321 is provided on the retaining plate 32, and a bolt 33 is installed in the bolt hole 321. The bolt 33 and the bolt hole 321 are threaded together. The end of the bolt 33 abuts against the side of the brake caliper 2. The mounting base 3 is then mounted on the brake caliper 2 via the retaining plate 32.

[0040] Reference Figure 3 and Figure 4 A movable groove 34 is provided on the mounting base 3, corresponding to the brake pad 21, and extending through the mounting base 3. A movable plate 5 is provided within the movable groove 34, parallel to the brake pad 21, and sliding within the groove towards the brake disc body 1. The friction pad 4 is located on the side of the movable plate 5 away from the brake pad 21. Initially, after the mounting base 3 is installed on the brake caliper 2, the friction pad 4 and the brake disc body 1 are spaced apart, i.e., the movable plate 5 and the brake disc body 1 are spaced apart. When processing of the brake disc body is required, the brake caliper 2 moves the brake pad 21 until it abuts against the movable plate 5, causing the movable plate 5 to move. The movable plate 5 then moves the friction pad 4 towards the brake disc body 1 until the friction pad 4 abuts against the surface of the brake disc body 1, allowing for processing of the brake disc body 1. The position of the friction pad 4 can be controlled by controlling the movement distance of the brake pad 21, thereby controlling the brake disc body 1.

[0041] Reference Figure 3 and Figure 4 An opening 35 is provided on the side of the mounting base 3 opposite to the rotation direction of the brake disc body 1. The opening 35 communicates with the movable groove 34. An insertion groove 51 is provided on the side of the movable plate 5 near the brake disc body 1, and the insertion groove 51 is located near the opening 35. An insertion interface 52 communicating with the insertion groove 51 is also provided on the side of the movable plate 5 near the opening 35. The friction pad 4 includes a mounting part 41 and a friction part 42. The friction part 42 is composed of multiple diamond particles and is located on the side of the mounting part 41 near the brake disc body 1. The mounting part 41 is inserted into the insertion groove 51 through the insertion interface 52. The friction part 42 protrudes to the outside of the insertion groove 51 so that the friction part 42 contacts the brake disc body 1 to process the brake disc body 1. By cooperating with the mounting part 41 and the insertion groove 51, friction pads 4 with different diamond particles can be replaced according to processing requirements to process the brake disc body 1. Meanwhile, the opening 35 and the insertion interface 52 are set on the side of the movable plate 5 away from the rotation direction of the brake disc body 1, so that after the friction pad 4 and the brake disc body 1 come into contact, the brake disc body 1 drives the friction pad 4 to move in the direction away from the opening 35, reducing the phenomenon of the friction pad 4 and the insertion groove 51 separating.

[0042] Reference Figure 5 and Figure 6A sliding groove 341 is formed on the inner wall of the movable groove 34. A slider 53 is provided on the side of the movable plate 5 near the inner wall of the movable groove 34. The slider 53 slides within the sliding groove 341 with the movable plate 5, meaning the sliding direction of the slider 53 is the same as the sliding direction of the movable plate 5. A reset element 6 is provided within the sliding groove 341. The reset element 6 can be a spring, which is positioned along the sliding direction of the slider 53. The spring is located on the side of the slider 53 away from the brake disc body 1, with one end connected to the inner wall of the sliding groove 341 and the other end connected to the slider 53. The spring drives the movable plate 5 to move in the direction away from the brake disc body 1. After adjusting the position of the movable plate 5 to process the brake disc body 1, the movable plate 5 moves to its initial position under the action of the reset element 6, allowing for the installation of the mounting base 3 or replacement of the friction pad 4.

[0043] Reference Figure 5 and Figure 6 To improve the surface treatment precision of the brake disc body 1, a placement groove 36 is provided in the mounting base 3, which is connected to the movable groove 34. An adjusting plate 7 is slidably disposed in the placement groove 36, sliding along a direction perpendicular to the sliding direction of the movable plate 5, and the adjusting plate 7 is located on the side of the mounting base 3 near the opening 35. The adjusting plate 7 is located on the side of the movable plate 5 away from the brake disc body 1. A guide slope 54 is provided on the movable plate 5 at a position corresponding to the adjusting plate 7, causing the thickness of the corresponding part of the movable plate 5 to gradually decrease, and the adjusting plate 7 and the guide slope 54 abut against each other. A control device 8 is provided on the mounting base 3, and the control device 8 and the adjusting plate 7 are used to adjust the position of the adjusting plate 7. The adjusting plate 7 moves to a position different from the guide slope 54, thereby driving the movable plate 5 to move and adjusting the position of the movable plate 5. By moving the adjusting plate 7 to adjust the position of the movable plate 5, the movement distance of the friction pad 4 can be controlled, improving the processing precision of the brake disc body 1.

[0044] Reference Figure 5 and Figure 6 A mating surface 71 is provided on the side corresponding to the adjusting plate 7 and the guide slope 54. The mating surface 71 is inclined and abuts against the guide slope 54. That is, the inclination of the mating surface 71 and the guide slope 54 is the same. When the adjusting plate 7 moves, the mating surface 71 remains in abutting state with the guide slope 54, which improves the stability of the fit between the adjusting plate 7 and the movable plate 5.

[0045] Reference Figure 5 and Figure 7An extension 37 is provided on the mounting base 3. The extension 37 is located outside the brake caliper 2. An extension groove 371 is provided inside the extension 37. The control device 8 includes a lever 81, an intermediate component 82, and a control lever 83. The control lever 83 is rotatably mounted in the mounting base 3 and is positioned along the sliding direction of the adjusting plate 7. A threaded portion 831 is provided on the control lever 83. The control lever 83 passes through the adjusting plate 7 and is threadedly connected to the adjusting plate 7 via the threaded portion 831. That is, when the control lever 83 is rotated, it drives the adjusting plate 7 to move via the threaded portion 831. The lever 81 is rotatably mounted in the extension groove 371, and its end extends to the outside of the extension 37. The end of the control lever 83 extends into the extension groove 371. The intermediate component 82 is located in the extension groove 371, and the control lever 83 and the lever 81 are connected via the intermediate component 82. A nut 811 is provided at the end of the control lever 83, and the nut 811 is located outside the extension groove 371. When adjustment is needed, the control lever 81 can be rotated using tools such as a wrench and nut 811. The control lever 81 drives the control lever 83 to rotate through the intermediate part 82, thereby adjusting the position of the adjustment plate 7.

[0046] Reference Figure 5 and Figure 7 A first gear 9 is disposed outside the control lever 83 and is located within the extension groove 371. The intermediate component 82 includes a worm gear 821, a worm wheel 822, a second gear 823, and a third gear 824. Both the second gear 823 and the third gear 824 are rotatably disposed within the extension groove 371. The second gear 823 is positioned between the first gear 9 and the second gear 824, meshing with both simultaneously. The worm wheel 822 and the third gear 824 are coaxially arranged. The worm gear 821 rotatably displaces within the extension groove 371, meshing with the worm wheel 822. The worm gear 821 is coaxially connected to the control lever 81. Rotation of the control lever 81 drives the worm wheel 822 via the worm gear 821, which in turn drives the control lever 83 to rotate via the third gear 824, the second gear 823, and the first gear 9, thereby adjusting the position of the adjusting plate 7. Meanwhile, the worm gear 822 and worm 821 have a self-locking mechanism, which reduces the phenomenon of the adjusting plate 7 shifting after the position of the adjusting plate 7 is adjusted, so that the friction plate 4 and the brake disc body 1 are stably engaged.

[0047] Reference Figure 5 and Figure 7Two sets of friction plates 4 and movable plates 5 are correspondingly arranged on both sides of the brake disc body 1. Two sets of control levers 83 and adjusting plates 7 are also correspondingly arranged. The extension 37 is positioned in the middle of the two sets of movable plates 5. Two worm gears 822 are provided. The worm 821 is positioned in the middle of the extension 37. The worm 821 meshes with both sets of worm gears 822 at the same time. That is, when the worm gears 822 are rotated, the two sets of movable plates 5 are moved at the same time, so that the two sets of friction plates 4 move synchronously, so that the friction force between the friction plates 4 and both sides of the brake disc body 1 remains the same, thereby improving the processing accuracy of the brake disc body 1.

[0048] The implementation principle of this application is as follows: The mounting base 3 is placed inside the brake caliper 2, and then the mounting base 3 is fixed to the brake caliper 2 using bolts 33 and a retaining plate 32. Then, the operating lever 81 is rotated, and the operating lever 81 drives the control lever 83 to rotate via the intermediate component 82. The control lever 83 drives the adjusting plate 7 to move, and the moving adjusting plate 7 drives the movable plate 5 to move. The movable plate 5 drives the friction pad 4 to move towards the brake disc body 1 until the friction pad 4 and the brake disc body 1 abut against each other. Simultaneously, the brake disc body 1 is rotated, and the surface of the brake disc body 1 is treated by the diamond particles on the surface of the friction pad 4, thereby increasing the coefficient of friction of the brake disc body 1. By setting the friction pad 4 on the movable plate 5 and adjusting the position of the friction pad 4 via the control lever 83, the brake disc body 1 is treated.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
