Description

Technical Field

[0001] The utility model relates to the field of wheel hub processing, in particular to a two-piece lightweight wheel hub. Background Art

[0002] The wheel hub refers to the component on the vehicle where the wheel is mounted. It is the connector between the wheel and the vehicle. The wheel hub is usually made of metal material and is sturdy and durable. Its main function is to support the wheel and enable it to rotate while bearing the weight and torque of the vehicle. The wheel hub can also provide the stability and handling performance of the vehicle, and plays an important role in the driving safety and comfort of the vehicle. The wheel hub usually consists of two main parts: the spokes and the rim. The spokes are the components that connect the wheel rim and the wheel axle. They are usually arranged in a spoke-like shape and can be divided into different shapes and quantities. The rim is the outer part of the wheel hub. It is a ring-shaped structure used to fix the tire. The rim is usually made of aluminum alloy or steel material and has high strength and durability.

[0003] The wheel hub is divided into single-piece wheel hub and multi-piece wheel hub. Single-piece wheel hub is more commonly formed in one piece, while multi-piece wheel hub adopts the separate assembly of spokes and rims. There are more two-piece wheel hubs. Compared with single-piece wheel hub, the rim and spokes of two-piece wheel hub can be adjusted according to user needs, and its diversified selection is higher. But at the same time, compared with single-piece wheel hub, its disadvantages are also obvious because the two-piece wheel hub adopts the rim and spokes separately, and the two are connected by bolts. In terms of connection stability, the materials of the two will also be selected with higher stability. The result is that the two-piece wheel hub is heavier, which will aggravate the energy loss caused by vehicle driving during use. At the same time, dust and dirt are easy to accumulate at the connection between the rim and the spoke, which will cause the bolts to rust and cannot be removed over time, making it difficult to maintain in the later stage, causing the entire wheel hub to be scrapped. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is that the two-piece wheel hub is separated from the rim and the spokes, and the two are connected by bolts. In terms of connection stability, the materials of the two are also selected to have higher stability. As a result, the weight of the two-piece wheel hub is relatively large, which will aggravate the energy loss caused by vehicle driving during use. At the same time, dust and dirt are easily accumulated at the connection between the rim and the spokes, which will cause the bolts to rust and cannot be removed over a long period of time, making it difficult to maintain in the later stage and causing the entire wheel hub to be scrapped.

[0006] (II) Technical solution

[0007] In order to solve the above problems, the utility model provides the following technical solutions:

[0008] A two-piece lightweight wheel hub comprises a wheel hub body, wherein the wheel hub body comprises a wheel rim and wheel spokes, a wheel spoke plate is provided on the inner side of the wheel rim, the wheel spoke plate is provided with the wheel spokes, the wheel spokes comprise a base, a connecting seat and wheel spokes, the base comprises a first base and a second base, a connecting threaded hole is provided on the first base, a fixing threaded hole is provided on the connecting seat, a first bolt is provided in the connecting threaded hole, the connecting seat is provided above the base, the wheel spokes are provided above the connecting seat, and a dustproof gasket is provided on the wheel spokes.

[0009] Furthermore, a bottom threaded hole is formed on the spoke plate, and the first bolt passes through the connecting threaded hole and is threadedly connected to the bottom threaded hole.

[0010] Furthermore, the connecting threaded hole passes through the first base, and the fixing threaded hole passes through the connecting seat and extends to the inside of the second base.

[0011] Furthermore, a spoke hole is provided at the end of the spoke, a second bolt is provided in the spoke hole, and the second bolt passes through the spoke hole and is threadedly connected to the fixing threaded hole.

[0012] Furthermore, the dustproof gasket is made of hard plastic material, and a clamping channel is provided on a side of the dustproof gasket close to the wheel spokes, and the clamping channel is made of rubber material and is in a circular ring shape.

[0013] Furthermore, the rim and the spokes are made of aluminum alloy, and the spokes are provided with a plurality of weight-reducing openings.

[0014] Furthermore, the weight-reducing opening is in the shape of a rectangular notch.

[0015] (III) Beneficial effects

[0016] The beneficial effects of the utility model are:

[0017] The weight of the overall two-piece wheel hub is reduced by using aluminum alloy, which is emerging in the market, as a material to replace traditional steel. While maintaining a stable structure, weight-reducing openings are opened to further reduce the weight of the wheel hub itself, making the wheel hub lightweight. At the same time, the spokes are made multi-element and installed in a multi-layer manner, so that the spokes can be removed layer by layer, and the connecting bolts of the outermost spokes are protected from external dust by dustproof washers to prevent dust, water vapor and dirt from entering the joints during driving and causing rust that cannot be removed. The spokes and spokes can be replaced in multiple layers, which is easy to disassemble and maintain, and the convenient maintenance increases the overall service life of the wheel hub.

[0028] See also Figure 2 A bottom threaded hole 8 is opened on the spoke plate 2a, and the first bolt 6 penetrates the connecting threaded hole 4 and is threadedly connected to the bottom threaded hole 8. The spoke plate 2a is used to connect the spoke 3 and the rim 2. The first bolt 6 is inserted into the bottom threaded hole 8 to thread the spoke 3 and the rim 2. Specifically, the first bolt 6 is inserted into the connecting threaded hole 4 on the base 3a, and penetrates the connecting threaded hole 4 and is threadedly connected to the bottom threaded hole 8.

[0029] See also Figure 3-Figure 5 The connecting threaded hole 4 passes through the first base 3aa, the fixing threaded hole 5 passes through the connecting seat 3b and extends to the inside of the second base 3ab. The function of the fixing threaded hole 5 is to fix the spoke 3c on the base 3a. The base 3a is connected to the rim 2 through the first bolt 6, and the second bolt 10 passes through the spoke hole 9 and extends to the fixing threaded hole 5 for threaded connection. The fixing threaded hole 5 is opened on the connecting seat 3b, passes through the connecting seat 3b and extends to the inside of the second base 3ab. Unlike the connecting threaded hole 4, the fixing threaded hole 5 does not pass through the second base 3a. b.
