Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wheel processing, specifically relating to a composite bayonet structure of wheel spokes and wheel rim. Background Technology
[0002] The rim and spokes are integrated into a single, stable unit. The structural dimensions of the composite surface between the spokes and rim are crucial to the final quality. Since the composite surfaces of the wheel hub are all straight, the placement of the spokes during the composite process is critical. Furthermore, the pressure from the welding head and the high temperature at the welding point during welding can significantly impact the final product quality due to localized deformation. This is especially true for two-tone products on the market, where the spokes and rim are pre-finished products that, after composite welding, form a complete wheel hub. The stability of the composite structure is even more critical. Currently, when the composite surfaces are all straight, the spokes are prone to displacement and deformation during welding, resulting in substandard parameters such as end diameter runout and balance in the final product.
[0003] Therefore, designing a composite bayonet structure for the spokes and rim that facilitates the assembly of the rim and spokes without relative slippage, further avoids deviations caused by welding, and ensures that the end diameter runout parameter is qualified, is an urgent problem to be solved. Utility Model Content

The snap-fit groove 111 is U-shaped, and the depth is not specifically limited, it can be 0.1mm-3mm, and it can be interference-fitted with the second snap-fit portion 21 to ensure that the wheel spoke 2 and the wheel rim 1 are tightly fitted and do not slide relative to each other, further avoiding deviations caused by welding, thereby ensuring that the end diameter runout parameter is qualified.
[0031] The first retaining part 11 is also provided with a first limiting protrusion 113, which abuts against the second retaining part 21. The first limiting protrusion 113 is generally triangular, but not limited to a triangle, and can also be a rectangle or other shapes, as long as it abuts against the second retaining part 21.
[0032] Specifically, the first limiting protrusion 113 has a first limiting surface 1131 and a first positioning surface 1132 that are connected to each other, and the first limiting surface 1131 abuts against the second holding part 21. The included angle formed by the first limiting surface 1131 and the first positioning surface 1132 is less than or equal to 90°.
[0033] The second holding part 21 is provided with a locking boss 211, which engages with the holding groove 111, and the locking boss 211 and the holding groove 111 are in an interference fit state.
