[0002] Disc brakes are now widely used in medium and heavy-duty truck tractors, buses, and long-distance buses.

[0003] Common disc brakes typically use floating caliper assemblies, which are generally quite heavy. When assembling the caliper assembly, one or two people usually lift the assembly while another person inserts bolts through the brake flange.

[0004] This assembly method makes it difficult to accurately position the clamp assembly in one go. It often requires multiple trial assemblies before it can be assembled in place, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0005] This application provides a clamp assembly support and vehicle to solve the problem that existing clamp assembly requires multiple trial assembly steps before it can be assembled in place, which is time-consuming, labor-intensive, and inefficient.

[0006] To solve the above problems, this application adopts the following technical solution:

[0007] The first aspect of this application provides a clamp assembly support for mounting a clamp assembly, comprising:

[0008] A bracket for connecting to the clamp body assembly, the bracket having at least one first threaded hole;

[0009] A positioning element, which is connected to the bracket;

[0010] The brake flange is provided with a second threaded hole that is adapted to the first threaded hole. The brake flange is also provided with a groove for the positioning member to be engaged, so that when the positioning member is engaged with the groove, the first threaded hole and the second threaded hole are opposite to each other.

[0011] At least one fastening bolt is provided for locking the brake flange and the bracket through the first threaded hole and the second threaded hole.

[0012] In some possible designs, the positioning element includes at least one positioning pin, the bracket has a pin hole, the positioning pin is interference-fitted with the pin hole, and the positioning pin extends at least partially outside the bracket, the groove includes a first groove that mates with the positioning pin, the inlet of the first groove being larger than the bottom of the first groove.

[0013] In some possible designs, the first channel includes a first guide segment and a rectangular segment connected to each other, the end of the first guide segment away from the rectangular segment being the inlet of the first channel, and the size of the first guide segment gradually decreasing along the direction closer to the rectangular segment.

[0014] In some possible designs, the width of the rectangular segment is greater than the diameter of the positioning pin. The positioning element also includes at least one limiting bolt. The bracket is provided with a third threaded hole, and the limiting bolt is threadedly connected to the third threaded hole. The groove also includes a second groove that mates with the limiting bolt. The second groove includes a second guide segment and an arc segment. The end of the second guide segment away from the arc segment is the entrance of the second groove. The size of the arc segment is adapted to the size of the limiting bolt.

[0015] In some possible designs, the first and second grooves are located on top of the brake flange, with the inlet of the rectangular segment located above the inlet of the arcuate segment.

[0016] In some possible designs, the size of the second guide segment gradually decreases along the direction close to the arcuate segment.

[0017] In some possible designs, both the first guide segment and the second guide segment are configured as funnel-shaped.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in sequences other than those illustrated or described herein.

[0050] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0051] Below, we will first explain some of the terms used in this application:

[0052] Caliper assembly: The floating caliper assembly is a component of the floating caliper disc brake, mainly used to work with the brake disc to achieve braking.

[0053] Currently, disc brakes can be classified into floating caliper disc brakes and fixed caliper disc brakes according to the form of the caliper assembly. Among them, floating caliper disc brakes have a relatively simple structure and are more advantageous in terms of price, lightweight, and size, so they are more commonly used in ordinary vehicles.

[0054] The caliper assembly of a floating caliper disc brake can slide slightly on the bracket. There is a piston on only one side of the caliper assembly and only one brake pad on the other side. When braking, the piston cylinder is activated and the piston moves. The brake pad on the piston cylinder side first contacts the brake disc. Then the entire caliper assembly moves under the reaction force, so that the brake pad on the other side of the caliper assembly contacts the brake disc, thereby performing braking.

[0055] In order to achieve effective braking, the caliper assembly is generally quite heavy. During assembly, one or two people usually lift the caliper assembly while another person inserts bolts from the brake flange side to fix the caliper assembly to the axle.

[0056] With this assembly method, it is difficult to position the clamp assembly in place in one go. Multiple trial assemblies are required before it can be assembled in place, which is cumbersome, time-consuming, labor-intensive, and inefficient.

[0057] To avoid the aforementioned problems, this application provides a clamp assembly support and vehicle, which can achieve quick and accurate positioning between the bracket and the brake flange through positioning components, thereby completing the assembly of the clamp assembly without multiple trial assembly attempts, effectively reducing the assembly difficulty of the clamp assembly and improving the assembly efficiency of the clamp assembly.

[0058] The technical solutions shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or similar content will not be repeated in different embodiments.

[0059] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment provides a clamp assembly support for mounting the clamp assembly 100 on the axle of a vehicle. The clamp assembly support includes a bracket 300, a positioning element 400, a brake flange 200, and fastening bolts 500.

[0060] The bracket 300 is connected to the clamp assembly 100 via a pin or similar means, allowing the clamp assembly 100 to slide slightly axially relative to the bracket 300 for braking. The bracket 300 has at least one first threaded hole 310, and the brake flange 200 has a second threaded hole 210 that mates with the first threaded hole 310, allowing a fastening bolt 500 to pass through and engage the brake flange 200. 0 and bracket 300 are locked together. Brake flange 200 is also used to connect to the axle, thereby mounting the caliper assembly 100 on the axle. Brake flange 200 is also provided with a groove for engaging with positioning element 400. Positioning element 400 is connected to bracket 300 and can be either detachable or fixed. When connecting brake flange 200 and bracket 300, positioning element 400 can be inserted into the groove for positioning, so that the first threaded hole 310 is aligned with the second threaded hole.

[0061] It is understandable that there can be one or more positioning elements 400, as long as the positioning elements 400 can achieve quick positioning of the brake flange 200 and the bracket 300.

[0062] Specifically, in use, first fix the clamp assembly 100 on the bracket 300, connect the positioning piece 400 to the bracket 300, then one person lifts the clamp assembly 100 and inserts the positioning piece 400 into the slot. After the positioning piece 400 is fully inserted into the slot, the first threaded hole 310 is exactly opposite to the second threaded hole 210. At this time, the clamp assembly 100 can be loosened, and the fastening bolt 500 can be directly screwed into the first threaded hole 310 and the second threaded hole 210 to achieve the connection between the bracket 300 and the brake flange 200.

[0063] By assembling the clamp assembly 100 in this way, it can be assembled in one go without the need for multiple trial assemblies, which makes the assembly of the clamp assembly 100 simpler and can also greatly improve the assembly efficiency of the clamp assembly 100.

[0064] In some possible implementations, the positioning member 400 includes at least one positioning pin 420, the bracket 300 is provided with a pin hole 330, the positioning pin 420 is interference-fitted with the pin hole 330, and the positioning pin 420 extends at least partially outside the bracket 300 to be inserted into the groove for positioning. The groove includes a first groove 230 that mates with the positioning pin 420, and the size of the inlet of the first groove 230 is larger than the size of the bottom of the first groove 230.

[0065] The length of the locating pin 420 extending beyond the bracket 300 can be around 5-20mm, for example, 10mm, so that the locating pin 420 can achieve a good positioning effect without affecting the assembly of the clamp body assembly 100.

[0066] For example, the first groove 230 can be configured as a funnel shape with a large inlet and a small bottom. This configuration makes it very easy to insert the positioning pin 420 into the first groove 230. As the positioning pin 420 moves toward the bottom of the first groove 230, the position of the bracket 300 will be adaptively adjusted. When the positioning pin 420 contacts the bottom of the first groove 230, the first threaded hole 310 on the bracket 300 can be exactly aligned with the second threaded hole 210 on the brake flange 200, thereby achieving rapid positioning of the bracket 300.

[0067] It is understood that the first groove 230 can also be any other shape, as long as it facilitates the insertion of the positioning pin 420, and after the positioning pin 420 and the first groove 230 are engaged in place, the first threaded hole 310 can be exactly opposite to the second threaded hole 210. This embodiment does not limit it.

[0068] Meanwhile, the positioning pin 420 and the pin hole 330 are detachably connected by an interference fit, which makes the connection between the positioning pin 420 and the bracket 300 simple. After the clamp body assembly 100 is assembled, the positioning pin 420 can be disassembled. In addition, during the assembly process, the positioning pin 420 and the bracket 300 can be prevented from separating, ensuring the positioning effect.

[0069] Further, please see Figure 7 , Figure 8 and Figure 9 As shown, the first groove 230 includes a first guide section 231 and a rectangular section 232 connected to each other. The end of the first guide section 231 away from the rectangular section 232 is the entrance of the first groove 230. The size of the first guide section 231 gradually decreases along the direction close to the rectangular section 232.

[0070] In use, the locating pin 420 first enters the first guide section 231. The entrance of the first guide section 231 is the largest, exceeding the size of the locating pin 420 by a large margin, making it easy for the locating pin 420 to enter the first guide section 231. After the locating pin 420 enters the first guide section 231, it can directly enter the rectangular section 232 along the first guide section 231, making it extremely easy for the locating pin 420 to enter the rectangular section 232. After the locating pin 420 enters the rectangular section 232 and connects with the bottom of the rectangular section 232, the first threaded hole 310 can then be aligned with the second threaded hole 210.

[0071] In some possible implementations, the width of the rectangular segment 232 is greater than the diameter of the positioning pin 420. The positioning member 400 also includes at least one limiting bolt 410. The bracket 300 is provided with a third threaded hole 320. The limiting bolt 410 is threadedly connected to the third threaded hole 320. The groove also includes a second groove 220 that mates with the limiting bolt 410. The second groove 220 includes a second guide segment 221 and an arc-shaped segment 222. The end of the second guide segment 221 away from the arc-shaped segment 222 is the entrance of the second groove 220. The size of the arc-shaped segment 222 is adapted to the size of the limiting bolt 410.

[0072] For example, one limit bolt 410 and one positioning pin 420 are provided, and the first groove 230 and the second groove 220 are respectively provided on both sides of the brake flange 200.

[0073] It is understood that the number of limit bolts 410 and positioning pins 420 can be one or more, and can be selected according to actual usage requirements. This embodiment does not limit them. Similarly, the positions of the first groove 230 and the second groove 220 can also be adjusted according to actual conditions. This embodiment does not limit them either.

[0074] In use, first insert the positioning pin 420 into the pin hole 330, then screw the limiting bolt 410 into the third threaded hole 320. Next, insert the positioning pin 420 into the first guide section 231 and the limiting bolt 410 into the second guide section 221. As the positioning pin 420 and the limiting bolt 410 are continuously pushed into the first groove 230 and the second groove 220, the first guide section 231 will guide the positioning pin 420 into the rectangular section 232. The width of the rectangular section 232 is greater than that of the positioning pin. The size of 420 makes it easier to insert the locating pin 420 into the rectangular segment 232. After the locating pin 420 is inserted into the rectangular segment 232, it can guide the position of the limiting bolt 410 accordingly, making it easier for the limiting bolt 410 to be inserted into the arc segment 222. The arc segment 222 is adapted to the shape of the limiting bolt 410. After the limiting bolt 410 is inserted into the arc segment 222, the position of the bracket 300 can be effectively adjusted so that the first threaded hole 310 and the second threaded hole 210 are aligned.

[0075] Furthermore, such as Figure 1 As shown, the first groove 230 and the second groove 220 are located on the top of the brake flange 200 (the end of the brake flange 200 closest to the caliper assembly 100 is the top of the brake flange 200), meaning that the inlets of both the first groove 230 and the second groove 220 are located on the top of the brake flange 200, and the inlet of the rectangular segment 232 is located above the inlet of the arc-shaped segment 222. Furthermore, the first groove 230 and the second groove 220 can be arranged vertically to facilitate easier insertion of the locating pin 420 and the limiting bolt 410 under the weight of the caliper assembly 100.

[0076] This allows the locating pin 420 to better assist the locating bolt 410 in inserting into the arc-shaped segment 222 after the locating pin 420 is inserted into the rectangular segment 232, making it easier for the locating bolt 410 to be inserted into the arc-shaped segment 222. Furthermore, the first groove 230 and the second groove 220 are positioned at the top of the brake flange 200, making it easier for the locating pin 420 and the locating bolt 410 to enter the first groove 230 and the second groove 220 during assembly.

[0077] In addition, the size of the second guide section 221 can be gradually reduced along the direction close to the arc section 222, so that the size of the inlet end of the second guide section 221 is much larger than the size of the limit bolt 410, so as to better guide the limit bolt 410 into the second groove 220.

[0078] Furthermore, both the first guide section 231 and the second guide section 221 are funnel-shaped, and the entrances of the first guide section 231 and the second guide section 221 are smoothly transitioned to the brake flange 200, so that the first guide section 231 and the second guide section 221 each have two inclined surfaces, which can better guide the positioning pin 420 and the limiting bolt 410 into the system.

[0079] Of course, the transition between the first guide segment 231 and the rectangular segment 232 can also be smooth, and the transition between the second guide segment 221 and the arc segment 222 can also be smooth, so as to avoid scratching between the positioning pin 420 and the first groove 230, and between the limiting bolt 410 and the second groove 220.

[0080] In some possible implementations, the second groove 220 is a through groove, and the length of the limiting bolt 410 extending beyond the bracket 300 is greater than the thickness of the brake flange 200, so that the limiting bolt 410 can better contact the second groove 220 and improve the positioning effect.

[0081] For example, the length of the positioning bolt extending beyond the bracket 300 is approximately 1 mm greater than the thickness of the brake flange 200.

[0082] Furthermore, the limiting bolt 410 is a flange bolt. The flange of the flange bolt is engaged with the end face of the brake flange 200 away from the bracket 300. That is, the flange and the surface of the brake flange 200 are tightly fitted. The flange bolt can be prevented from being misaligned by the flange and the brake flange 200, and the brake flange 200 and the bracket 300 can be prevented from separating. This further improves the positioning effect of the limiting bolt 410 on the bracket 300 and the brake flange 200.

[0083] Specifically, in use, the bracket 300 is connected to the clamp assembly 100, and the positioning pin 420 and the limiting bolt 410 are connected to the bracket 300. Then, one person lifts the clamp assembly 100, aligns the positioning pin 420 into the first guide section 231, and then gently places the clamp assembly 100. Under the weight of the clamp assembly 100, the limiting bolt 410 will slide into the second guide section 221. Subsequently, the positioning pin 420 enters the rectangular groove, and the limiting bolt 410 gradually moves into the guide section. Slide down into the arc section 222. At this point, the clamp body assembly 100 can be pre-installed through the dual positioning of the positioning pin 420 and the limit bolt 410. Then, the operator can release their hands and screw the fastening bolt 500 into the first threaded hole 310 and the second threaded hole 210 to fasten the brake flange 200 and the bracket 300. The whole process can be operated by a single person, saving time and effort. The assembly is simple and reliable, effectively reducing the assembly difficulty of the clamp body assembly 100 and significantly improving the assembly efficiency.

[0084] This application also provides a vehicle, which includes a clamp assembly 100, an axle, and a clamp assembly support as described in the above embodiments, the clamp assembly support being used to connect the clamp assembly 100 and the axle.

[0085] Specifically, the bracket 300 is connected to the clamp assembly 100, and the clamp assembly 100 can reciprocate along the bracket 300. The bracket 300 can adopt an existing structure, except that a structure for connecting with the positioning element 400 is added to the bracket 300. The brake flange 200 is also basically the same as the existing brake flange 200 in structure, except that a groove for cooperating with the positioning element 400 is provided on the brake flange 200, and the brake flange 200 is connected to the axle. The specific connection method is not limited in this embodiment. As long as the clamp assembly 100 is installed on the bracket 300, and then the bracket 300 is connected to the brake flange 200, the assembly between the clamp assembly 100 and the axle can be realized.
