Description

Technical Field

[0001] This invention relates to the field of automotive brakes, and particularly to a disc brake for automobiles and its assembly auxiliary equipment. Background Technology

[0002] With the rapid development of the automotive industry, vehicle safety and reliability have become a focus of attention for both consumers and manufacturers. As an important component of the automotive braking system, disc brakes have gradually become the mainstream braking device in modern vehicles due to their excellent heat dissipation performance, high braking efficiency, and long service life. However, many assembly processes of traditional disc brakes still rely on manual operation, which is inefficient, prone to human error, and makes it difficult to ensure stable assembly efficiency.

[0003] With the advancement of technology, technicians in related fields have optimized the technical means for assembling disc brakes. For a more accurate comparison, Chinese Patent Publication No. CN116039813A discloses an auxiliary device for installing chassis brake components, including a base plate and a drive mechanism. The drive mechanism includes an electric telescopic cylinder, a fixed disc, a support column, a bending column, and a traction component. The support column is fixedly connected to the base plate and located at the upper end of the base plate. The bending column is hinged to the support column and located at the upper end of the support column. The electric telescopic cylinder is fixedly connected to the bending column and embedded inside the bending column. The fixed disc is fixedly connected to the output end of the electric telescopic cylinder and located at the upper end of the electric telescopic cylinder. The traction component is fixedly connected to the base plate and located at the upper end of the base plate, and the output end of the traction component is fixedly connected to the fixed disc. In use, the brake disc can be supported through the cooperation between the base plate and the drive mechanism, without the need for long-term manual support, reducing the input of manual operation. Furthermore, it eliminates the need for manual handling to move the disc to the auxiliary device, thereby reducing the workload and making it safer and more reliable.

[0004] However, when using the above-mentioned device to assist in the assembly of disc brakes, the following problems still exist: The aforementioned device requires the brake disc to be clamped by a clamping mechanism on the disc body during use, and then the disc body is pulled by a traction component to achieve the required installation angle. This eliminates the need for manual handling and prolonged holding of the brake disc. However, since the disc body is confined to the bending column by a fixedly connected mounting block, and one end of the bending column is hinged to the support column, the bending column, mounting block, disc body, and brake disc as a whole need to be driven by traction to deflect around the hinge point between the bending column and the support column. The height of the disc body and mounting block is adjusted along the bending column. When the angle of the bending column and the height of the disc body are adjusted simultaneously (such as driving the disc body to slide to the middle section of the bending column or further down), the overall position of the adjusted disc body and brake disc is easily restricted, thus affecting the installation angle of the brake disc.

[0005] In addition, since the above-mentioned device needs to use the hinge between the bending column and the support column as the axis, the bending column will swing around its own length as the radius and the hinge as the axis during the rotation and swinging process to realize the clamping and limiting process of the brake disc. During this process, the length of the bending column itself is fixed, that is, its own rotation radius and range are also fixed, which will cause a large degree of offset between the initial clamping position and the final installation position of the brake disc.

[0006] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing technologies for auxiliary installation of brakes. Summary of the Invention

[0007] To address the aforementioned problems, the present invention provides an assembly auxiliary device for automotive disc brakes, comprising a brake disc and a limiting member for clamping and limiting the brake disc. The limiting member is spaced from the ground by a support column and is suspended at the upper end of the support column by an adjusting member. The adjusting member is also rotated on the support column to adjust the brake disc, which is limited by the limiting member, to the required installation angle.

[0008] The limiting component includes a support arm that is rotatably inserted into the support column and protrudes to one side. The support arm is symmetrically connected to a connecting shaft fixed to the support column on both sides. The connecting shaft is rotatably inserted into the support arm. One end of the support arm is provided with a clamping part.

[0009] Preferably, the clamping part includes a drive rod rotatably mounted on the support arm, and a mounting plate is rotatably connected to the end of the drive rod away from the support arm. The mounting plate is circumferentially limited by a plurality of driven support rods, and a guide groove is formed on the mounting plate corresponding to the driven support rods.

[0010] Preferably, the clamping part further includes a drive turntable for the upper limit of the drive rod, a guide rod is provided on the drive turntable corresponding to the driven support rod, a guide arc groove is provided on the drive turntable corresponding to the guide rod, and a limiting sleeve connected to the support arm is provided on the side of the mounting plate near the support arm, and the limiting sleeve is rotatably sleeved on the outer edge of the drive turntable.

[0011] Preferably, the driven support rod has an outer edge protrusion at the end away from the connected guide rod.

[0012] Preferably, a protective pad is provided on the side of the driven support rod corresponding to the outer edge protrusion.

[0013] Preferably, the adjusting component includes a mounting frame disposed on the side of the support column near the support arm, a rotating wheel rotatably connected to the mounting frame, a connecting frame fixed to the support column located below the mounting frame, a roller rotatably connected to the connecting frame, and a traction rope jointly limiting the rear section of the support arm, the rotating wheel, the mounting frame and the roller rotat, with one end of the traction rope connected to the support arm and the other end passing through the rotating wheel and wound around the roller rotat.

[0014] Preferably, a counterweight is connected to the end of the support arm away from the driven strut.

[0015] Preferably, the support column includes a horizontal mounting support column in contact with the ground or other fixed surface and two limiting guide plates symmetrically spaced at one end of the mounting support column, wherein the distance between the two limiting guide plates is at least not less than the width of the support arm.

[0016] In addition, this application also provides a disc brake for automobiles, in which the assembly auxiliary equipment for the disc brake is used to assist in the assembly of the various components of the disc brake, which includes at least a brake disc, a brake block and a pressing part. The brake disc is limited to one side of the column by a limiting member so as to facilitate the assembly of the brake block and the pressing part with the brake disc.

[0017] In summary, this application includes at least one of the following beneficial technical effects: I. This invention, through the cooperation between components such as the support arm, adjusting member, and support column, enables the support arm to deflect on the support column to adjust the height of the brake disc, while also allowing it to slide relative to the support column. This makes it easy for the brake disc, which is confined on the support arm, to reach the required installation angle, and at the same time, the rotation of the support arm will not restrict the installation angle of other components of the disc brake relative to the brake disc after it is confined.

[0018] Second, through the cooperation between components such as the support arm, connecting shaft, guide groove, rotating wheel and traction rope, the present invention enables the support arm to deflect around the connecting shaft while sliding relative to the connecting shaft along the guide groove. That is, during the deflection process, the lever arm of the support arm relative to the support column is also adjusted accordingly, so that its position will not be significantly offset during the clamping of the brake disc and the assembly of the brake, thus avoiding the occupation of a large space.

[0029] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 The embodiments of the present invention will be described in detail below.

[0030] This application discloses an automotive disc brake and its assembly auxiliary equipment. This application is mainly used in the assembly process of automotive disc brakes, providing technical assistance to workers in assembling the various components of the disc brake and the brake disc. Specifically, during assembly, the cooperation between the adjusting components, the support column, and the adjusting components clamps and limits the brake disc to be assembled, effectively avoiding the problem of workers needing to hold the brake disc for extended periods during assembly. Furthermore, this application can adjust the lever arm length of the support arm relative to the support column, ensuring that its position does not shift significantly during the clamping of the brake disc and the assembly of the brake, thus avoiding the occupation of a large space.

[0031] Example 1: Refer to Figure 1 As shown, a disc brake for automobiles includes a brake disc 1, with brake blocks symmetrically arranged at both ends of the brake disc 1 along its axial direction. A pressing part is provided between the two brake blocks, and the pressing part is floatingly connected to the brake disc 1 to drive the two brake blocks to resist each other on both sides of the brake disc 1, thereby achieving the effect of restricting the rotation of the brake disc 1 and the wheel.

[0032] Reference Figure 1 and Figure 2As shown, an assembly auxiliary device for automotive disc brakes includes a limiting member 2 for clamping and limiting the brake disc 1. The limiting member 2 is spaced from the ground by a support column 3 and is suspended at the upper end of the support column 3 by an adjusting member 4. The adjusting member 4 can also be rotated on the support column 3 to rotate the brake disc 1 to the required installation angle, thereby facilitating the assembly of the various components of the disc brake with the brake disc 1 by the workers. The lower end of the support column 3 can be fixedly connected to a caster trolley to increase mobility, or it can be directly fixed to the ground or other placement platforms by expansion bolts. Initially, the limiting member 2 is rotatably set at the upper end of the support column 3 and extends to one side (i.e., forming a long and short arm effect on both sides of the support column 3), so that the limiting member 2 itself is deflected towards the direction where the brake disc 1 is placed by its own gravity.

[0033] When it is necessary to assemble the brake disc 1, the limiting member 2 is released by the adjusting member 4 and driven to deflect towards the brake disc 1. After the limiting member 2 approaches the brake disc 1, it grips and limits the brake disc 1. Then, the adjusting member 4 drives the limiting member 2 to deflect in the opposite direction, causing the brake disc 1, which is limited by it, to deflect and slide synchronously until the brake disc 1 is adjusted to the required installation angle.

[0034] Reference Figure 2 and Figure 3 As shown, the limiting member 2 is used to clamp and limit the brake disc 1. Specifically, the limiting member 2 includes a support arm 20 that is rotatably inserted into the support column 3 and protrudes to one side. The two sides of the support arm 20 in the width direction are symmetrically connected to the connecting shafts 21 fixed on the support column 3. The connecting shafts 21 are rotatably inserted into the support arm 20 so that the support arm 20 as a whole is allowed to deflect and adjust about the two connecting shafts 21 as the axis. The support arm 20 has a center line with the position of the two connecting shafts 21 on the support column 3. The longer section extending to one side of the center line is the front section, and the shorter section extending to the other side of the center line is the rear section. The front section of the support arm 20 is provided with a clamping part 22.

[0035] In use, the support arm 20 and its front clamping part 22 are driven to deflect towards the direction where the brake disc 1 is placed. After the brake disc 1 is clamped by the clamping part 22, the support arm 20, clamping part 22 and the brake disc 1 that is limited are driven to rotate in the opposite direction until they are adjusted to the required angle so that the operator can assemble the squeezing part and the two brake blocks with the brake disc 1 to form a disc brake.

[0036] Reference Figures 3 to 5As shown, the clamping part 22 is used to clamp and limit the brake disc 1. Specifically, the clamping part 22 includes a drive rod 220 rotatably disposed at the front end of the support arm 20. The end of the drive rod 220 away from the support arm 20 is rotatably connected to a mounting plate 221. The mounting plate 221 is circumferentially limited by a number of driven support rods 222. A guide groove 223 is formed on the mounting plate 221 corresponding to the driven support rods 222, so that the driven support rods 222 can slide and adjust the radial position of the mounting plate 221 along the guide groove 223, thereby clamping and limiting the brake disc 1 so that the workers can assemble it.

[0037] In use, the driven support rods 222 on the mounting plate 221 are driven to slide relative to each other along the guide groove 223 so that the driven support rods 222 can all be inserted into the through holes of the brake disc 1. Then, the support arm 20, the drive rod 220, the mounting plate 221 and the driven support rods 222 are driven to deflect and slide towards the brake disc 1. After the drive rod 220 and the driven support rods 222 correspond to the through holes of the brake disc 1, the driven support rods 222 are driven to all be inserted into the through holes of the brake disc 1. Then, the driven support rods 222 are driven to slide radially outward from the mounting plate 221 along the guide groove 223 until each driven support rod 222 is abutted against the inner wall of the through hole of the brake disc 1, so as to achieve a stable clamping of the brake disc 1.

[0038] Reference Figure 4 and Figure 5 As shown, the clamping part 22 also includes a drive turntable 224 fixedly limited on the drive rotating rod 220. A guide rod 225 is provided on the drive turntable 224 corresponding to the driven support rod 222. A guide arc groove 226 is provided on the drive turntable 224 corresponding to the guide rod 225. A limiting sleeve 227 connected to the support arm 20 is provided on the side of the mounting plate 221 near the support arm 20. The limiting sleeve 227 is rotatably sleeved on the outer edge of the drive turntable 224.

[0039] During the rotation of the drive rod 220 and the drive turntable 224, the drive turntable 224 is simultaneously driven to rotate synchronously. This causes the drive rod 225 to deflect and slide relative to the drive rod 226. The rotational force generated by the drive turntable 224 as the drive rod 226 rotates tends to push the drive rod 225 to slide along the drive rod 226. However, due to the radial guidance and limitation of the driven support rod 222 and the drive rod 225 by the guide groove 223 on the mounting plate 221, the pushing force of the drive rod 225 by the drive groove 226 is transformed into a radial tangential force. This drives the drive rod 225 and the driven support rod 222 to slide and adjust along the guide groove 223, thereby driving the driven support rods 222 on the mounting plate 221 to slide and adjust relative to or opposite to each other, so as to clamp and limit them according to the size of the brake disc 1.

[0040] It should be noted that, under normal circumstances, a through hole is provided in the middle of the brake disc 1 of the disc brake for installation on the corresponding car wheel hub. Therefore, when clamping and limiting the brake disc 1 by the support arm 20 and the clamping part 22, it is only necessary to drive several driven support rods 222 to pass into the through hole on the brake disc 1, and then rotate the drive turntable 224 to drive several driven support rods 222 to slide in opposite directions and circumferentially abut against the through hole, so as to complete the clamping and limiting effect of the brake disc 1.

[0041] Reference Figure 4 and Figure 5 As shown, in order to prevent the brake disc 1 from slipping and falling off from the driven support rods 222, an outer edge protrusion 228 is provided at the end of the driven support rod 222 away from the connected guide rod 225. The outer edge protrusions 228 on the driven support rods 222 are distributed on the opposite sides of the two corresponding driven support rods 222 (two driven support rods 222 in the same radial direction of the mounting disc 221).

[0042] Reference Figure 4 and Figure 5 As shown, in order to increase the stability of the driven support rod 222 in clamping and limiting the brake disc 1, a protective pad 229 is also provided on the side of the driven support rod 222 corresponding to the outer edge protrusion 228. The protective pad 229 is preferably made of a material such as a rubber pad or a silicone pad that has a certain flexible deformation capability and at the same time has a large friction effect after deformation.

[0043] Reference Figure 6 As shown, the adjusting component 4 is used to limit and deflect the support arm 20. Specifically, the adjusting component 4 includes a mounting frame 40 that limits the support column 3 near the rear section of the support arm 20. A rotating wheel 41 is rotatably connected to the mounting frame 40. A connecting frame 42 is fixed to the lower side of the support column 3, and a roller post 43 is rotatably connected to the connecting frame 42. A traction rope 44 is used to limit the rear section of the support arm 20, the rotating wheel 41, the mounting frame 40, and the roller post 43. One end of the traction rope 44 is connected to the support arm 20, and the other end passes through the rotating wheel 41 and is wound around the roller post 43. Initially, the traction rope 44 is wound and tightened by the roller post 43 between the rear section of the support arm 20 and the rotating wheel 41, so as to initially limit and tighten the support arm 20 protruding from the support column 3, so that the support arm 20 as a whole maintains a horizontal balance at the initial stage.

[0044] In use, rotating the roller 43 forward releases the wound traction rope 44, causing it to loosen. Because the support arm 20 is limited to rotation on the support column 3 via the two connecting shafts 21 and the lengths of the front and rear sections are inconsistent, the center of gravity of the support arm 20 is closer to the front section. The front section of the support arm 20 always tends to deflect downward along the connecting shafts 21, pulling the released traction rope 44 to tighten. After the traction rope 44, which limits its position, is further released, the support arm 20 moves downward along the connecting shafts 21 towards the brake disc 1 to clamp and limit the brake disc 1. After clamping and limiting the brake disc 1, rotating the roller 43 in the reverse direction further tightens the traction rope 44. At this time, the roller 43 winds and tightens the traction rope 44, and the tightened traction rope 44 pulls the support arm 20 and the brake disc 1, which limits its position, upward to adjust to the required installation angle, facilitating the assembly of the disc brake by the staff.

[0045] Furthermore, referring to Figure 6 and Figure 7 As shown, in order to improve the convenience of workers assembling disc brakes, a counterweight 45 is connected to the rear section of the support arm 20. The weight range of the counterweight 45 is preferably such that, in the initial horizontal state, the total weight of the rear section of the support arm 20 plus the counterweight 45 is less than or equal to the total weight of the front section of the support arm 20. That is, the individual weight of the counterweight 45 or the rear section of the support arm 20 is less than the weight of the front section of the support arm 20. The traction rope 44 is connected to the counterweight 45, and guide grooves 210 are formed on both sides of the support arm 20 corresponding to the two connecting shafts 21 for sliding adjustment.

[0046] In use, after the traction rope 44 is loosened, the weight of the front section of the support arm 20 is greater than the weight of the counterweight 45 and the rear section of the support arm 20. The front section of the support arm 20 tends to deflect downward about the connecting shaft 21. After the support arm 20 deflects downward to a certain extent, the roller 43 is rotated to slowly wind up the loosened traction rope 44, so that the traction rope 44 maintains a tension effect on the support arm 20 as a whole, but does not completely prevent the deflection of the support arm 20. Under these circumstances, the support arm 20 tends to swing downward due to the influence of gravity. Part of the force is transformed into the tendency for the support arm 20 to slide downward relative to the connecting shaft 21, while the other part continues to drive the support arm 20 to swing downward. After the support arm 20 slides downward for a certain period of time or swings at a large angle, the roller column 43 is driven to rotate and slowly release the taut traction rope 44. This allows the support arm 20 to slide downward relative to the connecting shaft 21 while completing the downward swing, so that the driven support rod 222 at the front of the support arm 20 can approach the brake disc 1 to be assembled and clamp and limit it.

[0047] After clamping the brake disc 1, rotate the roller 43 to tighten the traction rope 44. The traction rope 44 pulls the deflected and slidable support arm 20 to rotate upward. After the support arm 20 drives the clamped brake disc 1 to rotate to a horizontal state, continue to drive the roller 43 to rotate to further tighten the traction rope 44. The tightened traction rope 44 will pull the counterweight 45, the support arm 20 and the brake disc 1 after it is limited to deflect upward. The front section of the support arm 20 and the brake disc 1 as a whole will be tilted upward, while the rear section of the support arm 20 will deflect downward relative to the front section. Under the combined action of its own weight and the weight of the connected counterweight 45, the downward deflected rear section of the support arm 20 has a tendency to continue to slide and deflect downward. Then slowly rotate the roller 43 to release the traction rope 44. The support arm 20 as a whole will continue to deflect upward (that is, the front section of the support arm 20 deflects upward and the rear section deflects downward).

[0048] Simultaneously, the guide grooves 210 on both sides slide downward relative to the connecting shaft 21. After the rear section of the support arm 20 abuts against the rotating wheel 41, the traction rope 44 between the counterweight 45 and the rotating wheel 41 will be pressed against the rear section of the support arm 20 and the counterweight 45. At the same time, the support arm 20 will press the part of the traction rope 44 through the rotating wheel 41 onto the rotating wheel 41. The support arm 20 and the rotating wheel 41 together form a clamping effect on the traction rope 44. The traction rope 44 also forms a curved section between one end of the counterweight 45 and the support arm 20. This curved section fits against the counterweight 45 and the support arm 20 to support and limit the tilted support arm 20 and the counterweight 45 as a whole. At this time, rotating the roller column 43 releases the traction rope 44. Under the combined gravity of the support arm 20 and the counterweight 45, the brake disc 1 at the front section of the support arm 20 can be driven to adjust its height (tilt downward).

[0049] After the support arm 20 is pressed against the rotating wheel 41, the traction rope 44, which is pressed between the rotating wheel 41, the counterweight 45, and the support arm 20, restricts the counterweight 45 and the support arm 20 from moving further downward. At this time, the roller 43 is rotated to tighten the traction rope 44. The traction rope 44 will then drive the rotating wheel 41 to rotate due to the pressure applied by the support arm 20. The contact between the rotating wheel 41 and the support arm 20 will restrict the support arm 20 from rotating further downward. Therefore, the traction rope 44, which is tightened at this time, has a tendency to be tightened and is pressed against the rotating wheel 41 by the support arm 20. The bent section of the traction rope 44 will exert a reaction force on the counterweight 45 and the support arm 20, pushing the support arm 20 and the counterweight 45 to slide on the rotating wheel 41 (sliding upward at an angle). This achieves the effect of driving the support arm 20 and the brake disc 1 to adjust their height, so as to assist the workers in assembly.

[0050] Furthermore, referring to Figure 6 and Figure 7As shown, the support column 3 includes a horizontal mounting support column 30 that contacts the ground or other fixed surface and two limiting guide plates 31 symmetrically spaced at one end of the mounting support column 30. The distance between the two limiting guide plates 31 is at least not less than the width of the support arm 20 so that the support arm 20 can rotate smoothly between the two limiting guide plates 31 (in a vertical state). The mounting frame 40 is fixedly installed on the two limiting guide plates 31, and the two connecting shafts 21 are respectively installed on the opposite sides of the two limiting guide plates 31.

[0051] In use, as the support arm 20 and its connected components such as the mounting plate 221, driven struts 222, and drive turntable 224 are driven downward and slide downward, the traction rope 44 is further released by rotating the roller column 43. This causes the support arm 20 and its connected components such as the mounting plate 221 to further deflect and slide until the support arm 20 and the mounting plate 221 are in a state that is relatively perpendicular to the horizontal plane. That is, the support arm 20 is rotated to a vertical position so that the driven struts 222 on the mounting plate 221 are axially aligned with the holes on the brake disc 1. This facilitates the clamping and limiting of the brake disc 1 and adjusts it to the required installation angle and height to assist the workers in assembling the disc brake.

[0052] Meanwhile, the support arm 20 is guided to slide and adjust in the vertical direction by the two limiting guide plates 31 and the traction rope 44, so that in the process of clamping several layer-by-layer stacked brake discs 1, it is not necessary to frequently adjust the stacking height of the other several brake discs 1 to adapt to the clamping process of the brake discs 1. Based on this, the length of the support arm 20 is greater than the height of the limiting guide plate 31.

[0053] It should be noted that in this embodiment, both the drive rod 220 and the roller 43 are driven by existing motor technology, which is a conventional existing technology and will not be described in detail here.

[0054] Example 2: Refer to Figure 7 and Figure 8 As shown, based on Embodiment 1, when the support arm 20 is driven to rotate to a vertical position and the guide groove 210 on it slides relative to the connecting shaft 21 to the limit position (i.e., the end of the guide groove 210), if the support arm 20, after being completely deflected and moved downward, is driven to move upward and rotate back to its original position by simply rotating the roller 43 to tighten the traction rope 44, a large pulling force needs to be applied to the traction rope 44. This requires the traction rope 44 itself to have high strength to adapt to the large tensile stress, which can easily lead to an additional increase in economic costs.

[0055] Therefore, in order to allow the support arm 20 to move upward and rotate back to its original position for adjustment after deflection and sliding to its limit, a buffer slide rod 5 is slidably inserted through the mounting frame 40. A buffer spring 50 is connected between the buffer slide rod 5 and the mounting frame 40, so that the buffer slide rod 5 is elastically floated and limited on the mounting frame 40. An extension block 51 is provided at the end of the buffer slide rod 5 away from the support arm 20, corresponding to the traction rope 44. A limiting through-hole 52 is formed on the extension block 51 for the traction rope 44 to pass through. Initially, the buffer slide rod 5 protrudes from the mounting frame 40 towards the side closer to the support arm 20.

[0056] In use, as the support arm 20 rotates from a horizontal to a vertical position, one side of the support arm 20 will contact the buffer slide bar 5 protruding from the mounting frame 40. As the support arm 20 continues to deflect, the support arm 20 will squeeze and push the buffer slide bar 5 to slide closer to the traction rope 44, and drive the buffer spring 50 to be compressed, thereby achieving a vibration buffering effect on the support arm 20 during the deflection process. The sliding of the buffer slide bar 5 will also drive the extension block 51 to slide synchronously, causing the extension block 51 and the limiting through hole 52 to push the traction rope 44 to deform (specifically, the traction rope 44 forms an arch at the extension block 51). The deformation of the traction rope 44 increases synchronously with the deflection amplitude of the support arm 20 until the support arm 20 rotates to a vertical position.

[0057] When it is necessary to drive the support arm 20 to rotate and move upward to reset, the traction rope 44 is tightened by rotating the roller 43. At this time, the arch formed by the traction rope 44 at the extension block 51 will tend to extend to both sides to restore the straight state due to the force. Therefore, the extension block 51 and the buffer slide 5 are pushed to slide closer to the support arm 20, and the buffer slide 5 is driven to push the support arm 20 to deflect first, so as to relieve the large tensile stress generated on the traction rope 44.

[0058] During operation: First, the support arm 20 is driven to swing on the support column 3 with the connecting shaft 21 as the axis, so that the clamping part 22 at the front of the support arm 20 can clamp and limit the placed brake disc 1. During the process of the support arm 20 swinging closer to the brake disc 1, the adjustment part 4 also drives the support arm 20 and the clamping part 22 to slide closer to the placed brake disc 1, so as to clamp and limit the brake disc 1, which facilitates the subsequent assembly process.

[0059] Step 2: After clamping and limiting the brake disc 1, drive the support arm 20 to slide and rotate away from the ground to reset, so as to drive the brake disc 1, which is limited by it, to adjust synchronously, thereby achieving the required installation angle. Step 3: During the process of adjusting the deflection and sliding of the support arm 20 relative to the support column 3, the adjustment component 4 guides its rotation and sliding path to ensure the stability of the brake disc 1 installation angle adjustment during use.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and not restrictive.

[0061] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
