Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a novel weight-reduction structure for aluminum alloy wheel hubs. Background Technology

[0002] In recent years, in response to the call for energy conservation and emission reduction and the booming popularity of electric vehicles, the pursuit of longer driving range has continued to intensify. Automobile manufacturers have also increased their research in this area, gradually replacing the heavier steel materials with lighter alloy materials. Against this backdrop, wheel manufacturers are also trying to reduce the weight of their wheels. However, after years of development, conventional weight reduction methods can no longer meet the demands of today's market. Therefore, for wheel manufacturers, the question of how to further reduce wheel weight is an urgent issue to address.

[0003] Therefore, a new type of aluminum alloy wheel hub weight reduction structure is needed to further reduce the weight of the wheel hub. The structure is simple and has little impact on the performance of the wheel hub. Utility Model Content

[0004] The purpose of this invention is to provide a novel weight-reducing structure for aluminum alloy wheels, which can effectively reduce the weight of the wheel hub while ensuring its load-bearing capacity. The spokes are milled on the side, giving the wheel hub a more layered look, meeting the market demand for aesthetics and lightweight design, and thus providing a reference direction for wheel hub weight reduction.

[0005] This utility model is implemented as follows: A novel weight-reducing structure for aluminum alloy wheels includes a hub center, spokes, and a rim. The hub center and rim are connected by several spokes. A window is a space enclosed by the hub center, spokes, and rim. A maximum solid structure is provided on the window. The maximum solid structure has a top, bottom, side, and end face. The maximum solid structure is achieved by milling the hub center and spokes. The maximum solid structure is located on the top of the hub center and spokes. The hub center has a center hole and bolt holes, which are evenly distributed around the center hole. The rim has valve holes.

[0006] Furthermore, the preferred wall thickness between the center hole and the bolt hole is ≥2mm. If the wall thickness is too thin, cracks are likely to occur during use. If the wall thickness is too thick, the wheel hub will become heavier. Both need to be designed according to the shape and structure of the wheel spokes and relevant tests should be conducted to verify their rationality.

[0007] Furthermore, the preferred maximum distance between the top of the largest solid structure and the adjacent shape on the front of the spoke is B≥3mm, the distance between the bottom of the largest solid structure and the back of the spoke is C≥5mm, and the maximum distance between the side of the largest solid structure and the adjacent shape on the spoke is D≥4mm. However, these requirements need to be adjusted according to the usage conditions and test results. The distance between the end face of the largest solid structure and the rounded corner at the root of the spoke is E≥3mm.

[0008] Compared with the prior art, the beneficial effects of this utility model are: this utility model provides a novel aluminum alloy wheel hub weight reduction structure, which further reduces the weight of the aluminum alloy wheel hub, thereby improving fuel economy and vehicle performance, as well as reducing energy consumption.
