Description

A lightweight aluminum alloy wheel hub

technical field

The utility model relates to an automobile wheel hub, in particular to a lightweight aluminum alloy wheel hub.

Background technique

Reducing the weight of the vehicle body is an effective way to improve vehicle performance and reduce vehicle energy consumption, and reducing the weight of the car wheel hub is an effective way to reduce the weight of the vehicle. Many existing automobile manufacturers use lighter aluminum alloys instead of cast iron casting wheels to achieve the purpose of reducing weight. However, many of these products only focus on appearance and ignore structural improvements, resulting in no further reduction in the weight of automobile wheels. In addition, the existing wheel hub has a relatively thick part at the junction of the spoke and the rim, which may easily cause casting defects such as dents and shrinkage porosity during the casting process due to the difference in casting thickness.

Utility model content

In order to overcome the shortcomings of the prior art, the utility model proposes a cast aluminum alloy wheel hub, which reduces weight by optimizing the structure.

The technical solution adopted by the utility model can be described as:

A light-weight aluminum alloy wheel hub, which includes a spoke and a rim integrally cast by aluminum alloy materials, wherein the spokes include a plurality of radially distributed spokes, a central hole is arranged in the center, and uniformly distributed around the central hole A plurality of mounting holes, the rim includes a rim main body and raised rims arranged on both sides of the rim main body, and the junction between the spokes and the rim is set at the same wall thickness as the rim main body.

The beneficial effects of the utility model are:

The light-weight aluminum alloy wheel hub proposed by the utility model adopts an equal-wall-thickness design on the joint between the spoke and the rim and on the main body of the rim, which realizes the lightweight design of the automobile wheel hub, not only improves the performance of the automobile, but also saves the energy consumption of the automobile , in line with the trend of low-carbon environmental protection, and eliminates casting defects caused by different thicknesses during the casting process.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

As shown in Figure 1, the lightweight aluminum alloy wheel hub proposed by the utility model includes two parts: a spoke 1 and a rim 2, both of which are formed by integral casting of high-strength aluminum alloy materials. The spoke 1 includes a plurality of radially distributed spokes 11, a center hole 12 is formed in the center, and a plurality of mounting holes 13 are uniformly distributed around the center hole 12 for fixing the hub on the wheel shaft. The rim 2 includes a rim main body 21 and raised rims 22 arranged on both sides of the rim main body 21 , and the junction 3 between the spokes 11 and the rim 2 is set at the same wall thickness as the rim main body 21 .

In this way, the lightweight aluminum alloy wheel adopts an equal-wall-thickness design at the joint between the spoke and the rim and the main body of the rim, which reduces the wall thickness at the joint between the spoke and the rim, realizes the lightweight design of the automobile wheel hub, and not only improves the The performance of the car and the energy consumption of the car are saved, which is in line with the trend of low-carbon environmental protection. In addition, the design of equal wall thickness effectively eliminates casting defects caused by different thicknesses during casting.

The above is only the preferred implementation of the utility model, and it does not constitute a limitation to the protection scope of the utility model, as long as the purpose of the utility model is realized by substantially the same means, all should belong to the protection scope of the utility model.
