Description

Technical Field

[0001] This utility model relates to the field of brake gear ring technology, specifically a brake gear ring. Background Technology

[0002] In the production and processing of brake gear rings, traditional brake gear rings mostly adopt an integral molding structure, that is, the gear ring body and key components such as teeth and mounting base are integrally processed by casting or forging. Although this structure can ensure the overall structural strength and stability of the gear ring and was widely used in early braking systems, obvious defects have gradually been exposed in actual use and maintenance. When the gear ring is partially damaged (such as tooth wear, breakage, or excessive wear in the contact area with the braking components due to long-term friction), since the overall structure is not disassembled, the maintenance personnel need to remove the entire gear ring from the hub or braking system for replacement. This not only requires disassembling related components such as bearings and hubs, but also involves complicated procedures, increases maintenance time and costs, and is prone to causing secondary damage to surrounding parts during disassembly.

[0003] Therefore, this utility model provides a brake gear ring to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved This invention provides a brake gear ring, which aims to solve the problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a brake gear ring, comprising a gear ring, an inner ring, and a base ring. Multiple sets of connecting blocks are fixedly installed on the inner wall of the inner ring. Each set of connecting blocks has a positioning groove, and slots are provided on both sides of the positioning groove. Multiple sets of positioning blocks are fixedly installed on the outer surface of the base ring along the circumferential direction. Through slots are provided on each set of positioning blocks. The positioning blocks and positioning grooves engage in a convex-concave fit to achieve pre-positioning. Locking components are provided within each set of positioning blocks to achieve a detachable and fixed connection between the positioning blocks and the connecting blocks. Heat dissipation components are provided on the gear ring and the inner ring to accelerate heat dissipation during braking.

[0006] As a preferred technical solution of this application, the locking assembly includes a locking rod that slides through the positioning block, and a connecting block is fixedly installed at the top of the locking rod. Grooves are provided on both sides of the two sets of connecting blocks, and springs are fixedly installed on the inner walls of the grooves. A locking pin is fixedly installed at the end of the spring, and the locking pin is adapted to engage with the groove to achieve circumferential fixation.

[0007] As a preferred technical solution of this application, the heat dissipation assembly includes multiple sets of heat dissipation ribs fixedly installed between the toothed ring and the inner ring. Multiple sets of air guide grooves are opened on the sides of the multiple sets of heat dissipation ribs along their length direction, and multiple sets of heat dissipation fins are fixedly installed on the multiple sets of heat dissipation ribs.

[0008] As a preferred technical solution of this application, the two ends of the multiple sets of heat dissipation ribs are welded and fixed to the toothed ring and the inner ring respectively, and the two ends of the heat dissipation ribs are triangular.

[0009] As a preferred technical solution of this application, the outer surface of the base ring is provided with multiple sets of square grooves, the length of which is greater than that of the locking rod, so as to provide space for the disassembly operation of the locking rod.

[0010] As a preferred technical solution of this application, multiple sets of screw rings are fixedly installed on the outer surface of the base ring.

[0011] As a preferred technical solution of this application, the outer surfaces of the multiple sets of positioning blocks are all covered with rubber to reduce the gap wobbling when the positioning blocks and connecting blocks are engaged.

[0012] (III) Beneficial Effects Efficient maintenance is achieved through modular disassembly and precise positioning design. The base ring and inner ring are pre-positioned by the interlocking of the positioning block and positioning groove, which can achieve initial docking without large-scale disassembly of the wheel hub and other surrounding parts, greatly simplifying the alignment operation in the early stage of installation. The locking component replaces the rigid connection of the traditional integrated structure by quickly engaging the spring-driven pin and the slot. When replacing local parts, the base ring and inner ring can be separated by simply unlocking from the square groove, avoiding the time loss and component damage risk caused by overall disassembly, and significantly reducing the difficulty of maintenance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a brake gear ring, such as Figures 1-6 As shown, the assembly includes a toothed ring 1 for engaging with a wheel speed sensor, an inner ring 3 for support and connection, a base ring 4 for fixing to the wheel hub, and multiple sets of connecting blocks 5 fixedly installed on the inner wall of the inner ring 3. Each set of connecting blocks 5 has a positioning groove 51, and slots 52 are provided on both sides of the positioning groove 51. Multiple sets of positioning blocks 42 are fixedly installed on the outer surface of the base ring 4 along the circumferential direction. Through slots 43 are provided on the multiple sets of positioning blocks 42. The multiple sets of positioning blocks 42 and the positioning grooves 51 are engaged to achieve pre-positioning. The engagement between the positioning blocks 42 and the positioning grooves 51 can quickly complete the pre-positioning, improving installation efficiency. Locking components are provided in the multiple sets of positioning blocks 42 to achieve detachable fixed connection between the positioning blocks 42 and the connecting blocks 5. Heat dissipation components are provided on the toothed ring 1 and the inner ring 3 to accelerate the dissipation of heat from the toothed ring 1 during braking.

[0017] The locking assembly includes a locking rod 7 that slides through the positioning block 42, and a connecting block 74 is fixedly installed at the top of the locking rod 7. Both sides of the two sets of connecting blocks 74 are provided with grooves 71, and springs 72 are fixedly installed on the inner wall of the grooves 71. A locking pin 73 is fixedly installed at the end of the spring 72. The locking pin 73 is adapted to engage with the slot 52 to achieve circumferential fixation. The locking pin 73 is driven by the spring 72 to engage with the slot 52, and the fastening can be completed without additional tools. The operation is convenient and can effectively limit the relative circumferential rotation of the positioning block 42 and the connecting block 5, ensuring connection stability. At the same time, the sliding locking rod 7 is easy to disassemble, providing convenience for subsequent maintenance.

[0018] The heat dissipation component includes multiple sets of heat dissipation ribs 2 fixedly installed between the toothed ring 1 and the inner ring 3. Multiple sets of air guide slots 21 are opened on the sides of the multiple sets of heat dissipation ribs 2 along their length direction, and multiple sets of heat dissipation fins 22 are fixedly installed on the multiple sets of heat dissipation ribs 2. The heat dissipation ribs 2 increase the heat conduction path between the toothed ring 1 and the inner ring 3, and can quickly dissipate the braking heat of the toothed ring 1. The air guide slots 21 can guide the airflow in a directional manner and improve the air convection efficiency. The heat dissipation fins 22 further expand the heat dissipation area. The combination of the two significantly enhances the heat dissipation effect and avoids the toothed ring 1 from degrading due to high temperature.

[0019] Among them, the two ends of multiple sets of heat dissipation ribs 2 are welded and fixed to the toothed ring 1 and the inner ring 3 respectively. The welding and fixing ensures that the heat dissipation ribs 2 are tightly connected to the toothed ring 1 and the inner ring 3. Moreover, the two ends of the heat dissipation ribs 2 are triangular. The triangular end design increases the welding contact area, enhances the connection strength, and can withstand the vibration and stress during the braking process.

[0020] The outer surface of the base ring 4 has multiple sets of square grooves 41, the length of which is greater than that of the locking rod 7. This provides space for the disassembly of the locking rod 7, making it easier for tools to reach in and press the locking pin 73, thus simplifying the disassembly process and reducing maintenance time. At the same time, the square grooves 41 can also help reduce weight and lower the overall weight of the gear ring.

[0021] Among them, multiple sets of threaded rings 6 are fixedly installed on the outer surface of the base ring 4. The threaded rings 6 provide a standardized interface for the connection between the base ring 4 and the hub, which facilitates a stable fixation by bolts.

[0022] The outer surfaces of multiple positioning blocks 42 are all covered with rubber to reduce the gap and shaking when the positioning blocks 42 and the connecting blocks 5 are mated, protect the mating surfaces of the positioning blocks 42 and the connecting blocks 5, and extend their service life.

[0023] Working principle: During the installation phase, the base ring 4 and the inner ring 3 are pre-positioned and connected. Multiple sets of positioning blocks 42 distributed circumferentially on the outer surface of the base ring 4 are aligned with the connecting blocks 5 on the inner wall of the inner ring 3, so that the positioning blocks 42 and the positioning grooves 51 on the connecting blocks 5 are precisely engaged. The initial axial and circumferential positioning is achieved by the cooperation between the two. At the same time, the rubber layer covering the outer surface of the positioning blocks 42 can fill the gaps and reduce shaking after installation. After the pre-positioning is completed, the locking and fixing operation is performed. The locking rod 7 is inserted into the through groove 43 of the positioning block 42 from the square groove 41 on the outer surface of the base ring 4. The connecting block 74 at the top of the locking rod 7 extends into the positioning groove 51 of the connecting block 5 at the same time. When the connecting block 74 is fully in place, the locking pin 73 corresponds to the locking groove 52 on the connecting block 5. The spring 72 pushes the locking pin 73 to pop out and fit into the locking groove 52, thereby realizing the circumferential and axial double fixing of the positioning block 42 and the connecting block 5, and firmly connecting the base ring 4 and the inner ring 3 into a whole. Subsequently, the entire gear ring structure is fastened to the vehicle wheel hub using bolts through multiple sets of threaded rings 6 on the outer surface of the base ring 4, ensuring that the gear ring rotates synchronously with the wheel hub.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
