Wheel

Abstract

The invention provides a wheel. The wheel comprises a rim and a spoke, wherein the rim comprises a rim body and a bent flange, the bent flange is connected with the edge of the rim body, and a first connecting surface is formed on the end surface, facing away from the rim body, of the bent flange; the part of the surface of the axial end of the spoke forms a second connecting surface, the spoke issubjected to laser welding with the first connecting surface through the second connecting surface, welding bead structures used for fixedly connecting the rim and the spoke are formed, the number ofthe welding bead structures is two, the one welding bead structure is located at the radial outer side of the contact position between the first connection surface and the second connection surface,and the other welding bead structure is located at the radial inner side of the contact position between the first connecting surface and the second connecting surface. The wheel solves the problem that the welding mode and the welding position of the wheel in the prior art are not reasonable, the structure of the wheel manufactured by machining is not stable, is poor in strength and cannot meet the use requirement of a wheel with a relatively long service life.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a structural improvement of a wheel. Background technique [0002] In the prior art, traditional welding methods such as gas shielded welding and submerged arc welding are usually used to fix the rim and spokes. The traditional welding method has a large heat-affected zone, which will reduce the strength of the wheel itself, resulting in poor structural stability of the wheel. And the structure of the weld bead structure on the wheel formed by the traditional welding method is unreasonable. Because the height of the weld bead structure is too large, it will affect the installation of the tire, cause air leakage, and easily cause safety accidents; in the prior art, Generally, a process of adding a turning process is adopted to remove the excessively high part of the weld bead structure, which increases the cumbersomeness of the wheel manufacturing process. In addition, when the w...
