Detailed ways

As shown in Figures 1-4, a wheel rim and aluminum spokes welded hub, including a rim 1 and a spoke 2, the rim 1 and the spoke 2 are welded and fixed, specifically, the inner wall of the rim 1 and the end of the spoke 2 The parts are welded and fixed, the material of the wheel rim 1 is iron or steel, the material of the wheel spoke 2 is aluminum alloy, the aluminum alloy model is A356, and the national standard is ZL101.

Compared with a wheel hub made of aluminum alloy as a whole, the wheel rim 1 is made of iron or steel, which can significantly reduce the cost of the wheel hub. In addition, the wheel rim is made of iron or steel, which may effectively improve the strength of the wheel hub. Since the style and style of the wheel spokes 2 are relatively complex, such as iron or steel, it would be difficult to manufacture. Therefore, the present application makes the wheel spokes made of aluminum alloy, which can significantly reduce the manufacturing difficulty and diversify the styles and structures. Since the rim 1 and the spoke 2 are made of different materials, the two are fixedly connected by welding, thereby forming an integrated structure with high structural stability.

The spoke 2 includes a spoke seat 3, and the spoke seat 3 is connected with a number of evenly spaced spoke assemblies 4. The ends of the spoke assemblies 4 are welded and fixed to the inner wall of the rim 1, so that the spoke 2 is connected to the rim 1 A fixed connection is formed to support the wheel rim 1 .

The spoke assembly 4 includes two spokes 5 arranged at an acute angle. One end of the spokes 5 is fixedly connected to the spoke base 3 , and the other end is fixed to the inner wall of the wheel rim 1 by welding. It should be noted that the spoke 2 is an integral structure, that is, the spoke 5 and the spoke seat 3 are integrally formed, and processes such as die casting and casting can be used.

The number of the spoke assemblies 4 is not limited. In this embodiment, there are three spoke assemblies 4 and they are fixed on the spoke base 3 evenly spaced from each other to form a stable triangular structure.

In this embodiment, the ends of the spokes 5 are tightly fitted with the inner wall of the rim 1 , and then welded and fixed, so that the ends of the spokes 5 are fixedly connected to the inner wall of the rim 1 .

The spoke 5 has a hollow groove 6, which can save the amount of aluminum alloy and further reduce the cost. The end of the spoke 5 close to the rim 1 is provided with a support and positioning block 7, and the support and positioning block 7 is located in the hollow groove 6. , the support positioning block 7 is welded and fixed with the inner wall of the wheel rim 1 . The end of the support and positioning block 7 is flush with the end of the spokes 5, which supports the inner wall of the rim 1 as a whole. In addition, the support and positioning block 7 also provides a larger welding area, so that the spokes 5 and the rim 1 Weld firmly. In this embodiment, there are six hollow grooves 6 in total, forming six welding points.

As a preferred solution, in order to make welding more reliable and convenient, one end of the support and positioning block 7 close to the wheel rim 1 is provided with a welding groove 8 , and the support and positioning block 7 is welded and fixed to the inner wall of the wheel rim 1 through the welding groove 8 .

Preferably, both the hollow groove 6 and the welding groove 8 face the inner side of the spoke seat 3 of the wheel rim 1 , which is the side of the spoke seat 3 that is close to the interior of the vehicle when the hub is installed. This arrangement makes the entire outer part of the wheel hub have a smooth and flat structure.

The welding groove 8 can be of various shapes. In order to facilitate the welding process, in this embodiment, a welding iron 9 is fixedly connected to the support and positioning block 7, and the welding iron 9 is close to one end of the rim and the support and positioning block 7. A welding groove 8 is formed between them, and the welding groove 8 is rectangular. The welding iron 9 is put into the mold as an insert and cast together with the aluminum alloy when the spoke 2 is cast. The shape of the welding iron 9 may not be limited. Make the section of the welding iron into an L-shape or other shapes with a bent structure. Preferably, the support and positioning block 7, the ends of the welding iron 9 and the ends of the spokes 5 are adapted to the shape of the inner wall of the wheel rim 1, so that they can be closely attached to each other to form a support fit.

In this embodiment, the width of the spokes 5 gradually decreases from one end close to the spoke holder 3 to the other end. The outer diameter of the rim 1 is 280mm, the width is 73.5mm, and the depth of the welding groove 8 is 13mm.
