Description

Technical Field

[0001] This technical solution relates to the field of electric vehicle wheel hub technology, specifically a disc brake mounting component. Background Technology

[0002] Common wheel hubs mainly include two types: drum brake hubs and disc brake hubs, each used to work with different brake systems to achieve braking. In electric vehicles, compared with drum brake hubs, disc brake hubs offer more linear braking force and a better user experience, thus gaining increasing popularity.

[0003] Existing disc brake hubs include reverse disc brake hubs. Common reverse disc brake hubs use a steel rim with multiple iron threaded joints. The reverse disc brake disc is also usually a steel disc, fixed to multiple threaded joints by multiple screws. When the brake clamps the reverse disc brake disc, the disc vibrates and collides with the threaded joints, producing abnormal noise. This noise can startle or cause tension and irritation for vehicle users, resulting in a poor user experience. Furthermore, the production efficiency of such threaded joints is very low. In the production of this type of rim, multiple iron threaded joints need to be manufactured through cutting, punching, and tapping, and then these joints are welded to the rim body. Due to the high hardness of iron, the cutting and other processing speeds are very slow, and quality problems are prone to occur, making it difficult to improve the yield rate of the threaded joints, thus affecting the production efficiency of both the rim and the hub. Summary of the Invention

[0004] The purpose of this technical solution is to provide a disc brake disc mounting component that connects the wheel rim and the disc brake disc. Specifically, multiple connecting parts that contact the mounting base are formed on the connector to increase the contact area between the connector and the mounting base, thereby solving the problems of complex and unstable connection in the original disc brake disc and wheel rim connection method.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A disc brake disc mounting assembly includes: a connector having a connecting portion one at its upper part and a connecting portion two at its lower part, the connector being mounted on a wheel rim via the connecting portion one and the connecting portion two; and a mounting base formed on the connector for mounting a disc brake disc; wherein, when the mounting base is formed on the connector, both the connecting portion one and the connecting portion two are exposed from within the mounting base; the connecting portion one extends to both sides along a mounting direction perpendicular to the connector, and the length of the connecting portion one is greater than the width of the connection between the mounting base and the connecting portion one.

[0007] Preferably, the second connecting part extends to both sides along the installation direction perpendicular to the connector, and the length of the second connecting part is greater than the width of the connection between the mounting base and the second connecting part.

[0008] Preferably, the connector has a hollowed-out center with four rounded corners.

[0009] Preferably, the first connecting part and the second connecting part are arranged perpendicular to each other.

[0010] Preferably, the mounting base is formed on the connector by casting, and the mounting base is made of aluminum.

[0011] Preferably, the connector is integrally formed by bending a sheet material, and the material of the connector is iron.

[0012] Preferably, the left and right sidewalls of the connector are formed with recesses, and the mounting base fills the recesses during the casting process.

[0013] Preferably, the top surface of the mounting base is a plane, which is the mounting surface of the disc brake disc.

[0014] Preferably, the top surface of the mounting base is formed with screw holes.

[0015] Preferably, the mounting base has a clearance groove located below the screw hole.

[0016] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0017] 1. The connector designed in this technical solution has a shape that adapts to the wheel rim, allowing both ends to be welded to the rim. It also has a shape that adapts to the mounting base, increasing the contact area between the connector and the mounting base. Connecting part one and connecting part two are located at the two ends of the connector, which are the welding positions during installation. The mounting base is formed in the middle of the connector. At the same time, connecting part one and connecting part two are widened to increase the welding points between the connector and the wheel rim, thereby increasing the connection strength between the two and allowing the disc brake disc to be installed more stably on the wheel rim.

[0018] 2. The connector designed in this technical solution has a recessed structure on its side wall. When the mounting base is cast, the molten aluminum will fill the recessed structure. The recessed structure can also avoid a smooth connection between the mounting base and the connector. In this way, when the mounting base covers the side wall of the connector, the contact area between the two increases, making it less likely to break. Attached Figure Description

[0024] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, this technical solution provides a disc brake disc mounting assembly, which needs to be installed on the wheel hub and is used to install the disc brake disc. The structure of the mounting assembly is designed based on the structure of the wheel hub and the disc brake disc as well as the installation requirements. Therefore, the structure of the wheel hub and the disc brake disc will be briefly described below.

[0026] The disc brake disc is roughly circular in shape, with a circular inner edge and a gear-shaped outer edge. The disc brake disc has multiple fixing holes, which can be used to detachably install the disc brake disc onto the mounting assembly using screws. Then, the mounting assembly is connected to the wheel hub, thus completing the installation of the disc brake disc onto the wheel hub.

[0027] A wheel hub consists of a rim and spokes. Mounting components need to be installed on the rim, and the installation method is generally welding. In the actual installation process, several mounting components are arranged axially on a rim. Each mounting component is installed in the axial direction of the rim. Part of the mounting component is connected to the side of the rim, part is connected to the inner wall of the rim, and the rest of the mounting component needs to be adapted to the shape of the rim.

[0028] like Figure 1-4 As shown, a disc brake mounting assembly includes a connector 1 and a mounting base 4 that are connected to each other. The connector 1 and the wheel rim are made of the same material, so they can be connected by welding. In this embodiment, the connector 1 and the wheel rim are both made of iron, and the mounting base 4 is made of aluminum according to structural and process requirements. Therefore, the mounting base 4 is connected to the connector 1 by casting. After casting is completed, the mounting base 4 partially covers the connector 1, which increases the connection strength between the two.

[0029] like Figure 2-4 As shown, the connector 1 is integrally formed by bending a sheet material, and after forming, it is approximately an inverted "L" shape. The upper part of the connector 1 has a horizontally placed connecting part 2, and the lower part has a vertically placed connecting part 3. The connector 1 can be welded to the wheel rim through the connecting part 2 and the connecting part 3.

[0030] After the mounting base 4 is formed on the connector 1, both the first connecting part 2 and the second connecting part 3 are exposed from the mounting base 4. The exposed first connecting part 2 and the second connecting part 3 facilitate the welding of the connector 1 to the rim. Both the first connecting part 2 and the second connecting part 3 extend to both sides along the installation direction perpendicular to the connector 1. Here, the installation direction perpendicular to the connector 1 is the direction parallel to the surface of the rim. The first connecting part 2 extends to both sides along the surface of the rim, and the second connecting part 3 extends to both sides along the inner wall of the rim. The length of the first connecting part 2 is greater than the width of the connection between the mounting base 4 and the first connecting part 2, and the length of the second connecting part 3 is greater than the width of the connection between the mounting base 4 and the second connecting part 3, that is, L2>L1, L4>L3. By widening the design of the first connecting part 2 and the second connecting part 3, the number of welding points between them and the rim can be increased, thereby increasing the connection strength between the two.

[0031] The connecting part 1 2 and the connecting part 2 3 are bent at a certain angle. This arrangement can increase the number of contact points and the contact area between the connecting part 1 and the rim. It can also increase the contact area between the connecting part 1 and the mounting base 4 within a limited space, thereby increasing the connection strength between the disc brake disc and the rim.

[0032] like Figure 2-4 As shown, the mounting base 4 is generally in the shape of a column with a missing corner. The mounting base 4 has a top surface for mounting the disc brake disc and a side surface for connecting the connector 1. The mounting base 4 is connected to the connector 1 by casting.

[0033] like Figure 2-4 As shown, the connector 1 has a hollow 5 in the middle. The design of the hollow 5 can realize the rapid casting of molten aluminum. During casting, the molten aluminum can quickly fill the mold, improve the production efficiency of the installation component, and form the connector 1 and the mounting base 4 that are intertwined with each other, making the connection between the two tighter and increasing the physical strength of the entire installation component.

[0034] Furthermore, all four corners of the hollow 5 are rounded 6. The rounded corners 6 ensure that the corresponding positions inside the mounting base 4 after molding will not become sharp corners that are easily damaged under stress, thus making the connection strength between the mounting base 4 and the connector 1 higher.

[0035] like Figure 2 and Figure 3 As shown, at least one recess 8 is formed on the left and right side walls of the connector 1. The mounting base 4 will fill the recess 8 during the casting process. The recess 8 can increase the bonding strength between the mounting base 4 and the connector 1.

[0036] like Figure 3As shown, the top surface of the mounting base 4 has a screw hole (not shown in the figure). The screw hole can be easily formed on the aluminum mounting base 4, which is why the mounting base 4 is made of aluminum. The mounting base 4 has a relief groove 9, which is located below the screw hole. The shape of the relief groove 9 is also adapted to the structure of the wheel rim, because the side of the mounting base 4 with the relief groove 9 needs to contact the wheel rim.
