Description

Technical Field

[0001] The utility model relates to the automobile manufacturing industry, and particularly relates to a high-strength 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 spokes. The shape of the spokes 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 a more beautiful appearance. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a high-strength spoke-type aluminum alloy automobile wheel hub with novel structure, high spoke strength, diverse shapes, strong three-dimensional sense and beautiful appearance.

[0004] To achieve the above purpose, the utility model comprises a wheel core, a rim and a plurality of circumferentially evenly distributed spokes. Each spoke comprises a radial spoke and two inclined spokes symmetrically arranged on the left and right sides of the radial spoke. An arc-shaped protrusion is arranged on the front surface of the inclined spoke. A circular blind hole is arranged in the middle part of the arc-shaped protrusion, and a hexagonal protrusion is arranged in the middle part of the bottom surface of the circular blind hole. A kidney-shaped blind hole is arranged on the front surface of the radial spoke. The upper part of the inclined spoke is connected with the rim, the lower part of the inclined spoke is connected with the radial spoke, and the lower end of the radial spoke is connected with the wheel core.

[0005] Since the utility model adopts a plurality of circumferentially evenly distributed spokes composed of a radial spoke and two inclined spokes symmetrically arranged on the left and right sides of the radial spoke, after using the aluminum alloy automobile wheel hub with such spokes, on the one hand, the strength of the spokes can be improved, and on the other hand, an arc-shaped protrusion is arranged on the front surface of the inclined spoke, a circular blind hole is arranged in the middle part of the arc-shaped protrusion, and a hexagonal protrusion is arranged in the middle part of the bottom surface of the circular blind hole. A kidney-shaped blind hole is arranged on the front surface of the radial spoke. These structures can make the shape of the aluminum alloy automobile wheel hub more diverse, the three-dimensional sense stronger and the appearance more beautiful. The utility model has novel structure, high spoke strength, diverse shapes, strong three-dimensional sense and beautiful appearance. Description of the Drawings

[0009] Refer to Figures 1 to 3 , the utility model comprises a wheel hub 1, a rim 2 and a plurality of radially distributed spoke plates 3. Each spoke plate 3 comprises a radial spoke plate 32 and two inclined spoke plates 31 symmetrically arranged on the left and right sides of the radial spoke plate 32. An arc-shaped protrusion 311 is arranged on the front surface of the inclined spoke plate 31. A circular blind hole 3111 is arranged in the middle of the arc-shaped protrusion 311. A hexagonal protrusion 3112 is arranged in the middle of the bottom surface of the circular blind hole 3111. A waist-shaped blind hole 321 is arranged on the front surface of the radial spoke plate 32. The upper part of the inclined spoke plate 31 is connected with the rim 2. The lower part of the inclined spoke plate 31 is connected with the radial spoke plate 32. The lower end of the radial spoke plate 32 is connected with the wheel hub 1.
