Description

Technical Field

[0001] This utility model relates to the automotive manufacturing industry, specifically to an automotive aluminum alloy wheel hub with combined arc-shaped grooves. Background Technology

[0002] Most existing spoke-type automotive aluminum alloy wheels use a structure consisting of a rim, a hub, and several spokes. As users' demands for personalization continue to increase, most users require spokes to have a stronger three-dimensional feel and a more aesthetically pleasing appearance. However, existing spoke-type automotive aluminum alloy wheels cannot meet these user needs. Utility Model Content

[0003] The purpose of this utility model is to provide an automotive aluminum alloy wheel hub with a combined arc groove that has a novel structure, rich shapes, strong three-dimensional effect, and beautiful appearance.

[0004] To achieve the above objectives, this utility model includes a wheel, which includes a rim, a core, and several circumferentially distributed spokes. A combined arc-shaped groove is provided between every two adjacent spokes. The combined arc-shaped groove includes two symmetrically arranged concave arc grooves. The upper part of the concave arc groove is located on the side of the spoke, and the lower end of the concave arc groove is connected to the core. The cross-section of the concave arc groove is circular, and the groove depth is deeper in the middle and shallower at the two sides.

[0005] This invention features a combined arc-shaped groove composed of two symmetrically arranged concave arc grooves between every two adjacent spokes, resulting in a variety of shapes, a more aesthetically pleasing appearance, and a stronger three-dimensional effect for automotive aluminum alloy wheels. This invention boasts a novel structure, diverse shapes, a strong three-dimensional effect, and an attractive appearance. Attached Figure Description
