Description

Technical Field

[0001] The utility model relates to the automobile manufacturing industry, and more specifically to a stepped spoke type aluminum alloy automobile wheel hub. Background Art

[0002] Most of the existing spoke type aluminum alloy automobile wheel hubs adopt a structure composed of a rim, a wheel core and a plurality of spoke plates. The shape of the spoke plates of the existing aluminum alloy automobile wheel hubs is relatively simple and the appearance is relatively monotonous. With the continuous improvement of users' personalized needs, the traditional spoke type aluminum alloy automobile wheel hubs can no longer meet the needs of users, and the general trend is to develop towards a more diverse shape and more beautiful appearance. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a stepped spoke type aluminum alloy automobile wheel hub with a rich shape, strong three-dimensional sense and beautiful appearance.

[0004] To achieve the above purpose, the utility model includes a wheel core, a rim and a plurality of circumferentially evenly distributed spoke plates. A central hole is provided in the middle part of the wheel core. Each spoke plate includes a first step, a second step and a straight spoke plate which are arranged in sequence from top to bottom. A circular hole is provided in the middle part of the connection between the first step and the second step. A kidney-shaped hole is provided in the middle part of the straight spoke plate. The center line of the kidney-shaped hole is tangent to the central hole of the wheel core. The upper part of the first step of the spoke plate is connected to the rim. The lower end of the first step is connected to the upper end of the second step. The lower end of the second step is connected to the upper end of the straight spoke plate. The lower end of the straight spoke plate is connected to the wheel core.

[0005] Since the utility model adopts a plurality of circumferentially evenly distributed spoke plates composed of a first step, a second step and a straight spoke plate, a circular hole is provided in the middle part of the connection between the first step and the second step, and a kidney-shaped hole is provided in the middle part of the straight spoke plate, and the center line of the kidney-shaped hole is tangent to the central hole of the wheel core. After adopting these structures, the shape of the aluminum alloy automobile wheel hub can be made more diverse, the three-dimensional sense can be stronger, and the appearance can be more beautiful. The utility model has a rich shape, strong three-dimensional sense and beautiful appearance. Brief Description of the Drawings

[0007] Figure 2 is Figure 1 the enlarged A-A sectional view in Detailed Embodiment

[0008] See Figures 1 to 2, the utility model includes a wheel core 1, a wheel rim 2 and a plurality of radially evenly distributed spoke plates 3. A central hole 11 is provided in the middle part of the wheel core 1. Each spoke plate 3 includes a first step 31, a second step 32 and a straight spoke plate 34 which are arranged in sequence from top to bottom. A round hole 33 is provided in the middle part of the connection between the first step 31 and the second step 32. A kidney-shaped hole 341 is provided in the middle part of the straight spoke plate 34. The center line 3411 of the kidney-shaped hole 341 is tangent to the central hole 11 of the wheel core 1. The upper part of the first step 31 of the spoke plate 3 is connected to the wheel rim 2. The lower end of the first step 31 is connected to the upper end of the second step 32. The lower end of the second step 32 is connected to the upper end of the straight spoke plate 34. The lower end of the straight spoke plate 34 is connected to the wheel core 1.
