Description

Technical Field

[0001] This utility model belongs to the field of wheel hub technology, and specifically refers to a wheel hub structure with a brake disc. Background Technology

[0002] Currently, two-wheeled vehicles (including electric vehicles, motorcycles, etc.) commonly use disc brake hubs, disc brake discs, and corresponding brakes. The disc brake disc is mounted on the outer side of the disc brake hub's axial direction, and the brake is used to clamp the disc brake disc and generate friction, thereby causing the disc brake disc to drive the disc brake hub to slow down or stop rotating for braking. One type of disc brake disc is a full-disc disc with a diameter close to the hub diameter, also known as a reverse disc brake disc. In order to install such a large disc brake disc on the hub, existing disc brake hubs usually have a threaded seat on the rim, and the full-disc disc brake disc is fixed to the threaded seat by corresponding screws. Common hubs on the market are made of iron, including the rim, brake disc, and the threaded seat for connecting the two. The above-mentioned materials have low manufacturing costs and good strength, but they also have some problems: welding the threaded seat to the hub is inconvenient and difficult to process, the processing speed is slow, and the overall precision is not high. Utility Model Content

[0003] The purpose of this utility model is to provide a wheel hub structure with brake disc that is simple and reasonable in structure, connects the fixing column body to the wheel hub through connectors of different materials, reduces production difficulty, increases production speed, and ensures stability in use.

[0004] The purpose of this utility model is achieved as follows:

[0005] A wheel hub structure with a brake disc includes a brake disc and a wheel hub. A plurality of fixing posts are provided between the wheel hub and the brake disc. Each fixing post includes a fixing post body and a connector. The fixing post body and the connector are integrally formed. The connector extends at least partially out of the fixing post body and is fixedly connected to the wheel hub. The fixing post is provided with a threaded hole for easy connection with the brake disc.

[0006] In the above-mentioned wheel hub structure with brake disc, the connecting member is basically an L-shaped structure, with both ends of the connecting member extending out of the fixing post body and being fixedly connected to the wheel rim and the inner sidewall of the wheel hub, respectively.

[0007] In the above-mentioned wheel hub structure with brake disc, the connecting part includes a connecting part and a fixing part. The connecting part is located inside the fixing post body, and the fixing part extends out of the fixing post body and is located on both sides of the connecting part. The fixing post body is provided with an auxiliary positioning groove, which is located above the fixing part that is fixedly connected to the wheel rim of the wheel hub.

[0008] In the above-described wheel hub structure with brake disc, the width H of the fixing part is greater than the width h of the connecting part.

[0009] In the above-mentioned wheel hub structure with brake disc, the connecting part is provided with two creases, and the connecting part is also provided with a reinforcing strip, which is located between the two creases.

[0010] In the above-mentioned wheel hub structure with brake disc, there are two connecting members, which are located inside the left and right ends of the fixing column body, respectively.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] Example 1, as Figures 1-4 The diagram shows a wheel hub structure with a brake disc, including a brake disc 1 and a wheel hub 2. Multiple fixing posts 3 are provided between the wheel hub 2 and the brake disc 1. Each fixing post 3 includes a fixing post body 31 and a connecting member 32, which are integrally formed. At least a portion of the connecting member 32 extends out of the fixing post body 31 and is fixedly connected to the wheel hub 2. The fixing post 3 is provided with threaded holes 33 for easy connection with the brake disc 1. Specifically, the threaded holes are designed to facilitate the fixed connection of the brake disc. The brake disc has through holes that mate with the threaded holes. Bolts pass through the brake disc and connect to the threaded holes, thus fixing the brake disc in place. The fixed post is fixedly connected to the wheel hub by a connector, wherein the connector and the wheel hub are connected to each other by welding. The brake disc 1 is equipped with a brake 4 connected to the vehicle body. The brake 4 is located on the inner ring of the brake disc 1. The brake disc is equipped with a brake ring 41, which is evenly distributed with a number of heat dissipation holes. The outer periphery of the brake disc extends outward to form a number of fixed plates 42 connected to the fixed post 3. A heat dissipation plate 43 is provided between two adjacent fixed plates 42. The heat dissipation plate 43 is provided with a heat dissipation groove 44. A heat dissipation groove 45 is provided between the brake ring and the heat dissipation plate to increase the heat dissipation effect.

[0029] In the above-described wheel hub structure with brake disc, the connector 32 is basically L-shaped. Both ends of the connector 32 extend out of the fixing post body 31 and are fixedly connected to the rim of the wheel hub 2 and the inner sidewall of the wheel hub 2, respectively. The connector 32 includes a connecting part 321 and a fixing part 322. The connecting part 321 is located inside the fixing post body 31, and the fixing part 322 extends out of the fixing post body 31 and is located on both sides of the connecting part 321. An auxiliary positioning groove 34 is provided on the fixing post body 31. The auxiliary positioning groove 34 is located above the fixing part 322, which is fixedly connected to the rim of the wheel hub 2. Specifically, the auxiliary positioning groove is used to facilitate the forming of the connector after the auxiliary pressure block in the mold is fixed. To be precise, it is the auxiliary pressure block forming groove in the mold. The two fixing parts on the same connector are perpendicular to each other, which is to facilitate welding to the rim of the wheel hub and the inner sidewall of the wheel hub.

[0030] In the above-mentioned wheel hub structure with brake disc, the width H of the fixing part 322 is greater than the width h of the connecting part 321. The connecting part 321 is provided with two creases 323, and a reinforcing strip 324 is also provided on the connecting part 321. The reinforcing strip 324 is located between the two creases 323. Specifically, this can improve the overall strength and toughness of the connecting parts.

[0031] In the above-mentioned wheel hub structure with brake disc, there are two connecting members 32, which are located inside the left and right ends of the fixing column body 31, respectively. Specifically, using two connecting members can further improve the overall connection strength of the fixing column.

[0032] Example 2 is basically the same as Example 1, except that, as follows: Figure 5 As shown: A connecting sleeve 327 is provided between the two connecting parts 32. The connecting sleeve 327 has an internal thread 325 at its center. The upper surface of the connecting sleeve 327 is flush with the upper surface of the fixing column body 31. Specifically, the connecting sleeve and the connecting parts are made of the same material. The connecting sleeve and the connecting parts can be connected to each other by welding first, and then the connected connecting sleeve and the connecting parts are formed into a connecting column by die casting.

[0033] Example 3 is basically the same as Example 1, except that, as follows: Figure 6 and Figure 7 As shown: A connecting plate 326 is provided between the two connecting parts 32. Specifically, the connecting plate is designed to be close to the inner part of the wheel hub, which can increase the welding length and increase the connection between the fixing post and the wheel hub.

[0034] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
