Problems solved by technology
[0004] The main purpose of the present invention is to provide a wheel to solve the problem that the spokes and the rim of the wheel in the prior art cannot be reliably locked before welding, which reduces the installation accuracy of the spokes, and after the two are assembled, there is a problem between the two. The contact area between the spokes is too small to ensure that the spokes provide stable and reliable support for the rim

The invention provides a wheel which comprises a rim, a spoke, a positioning element and a fastener, the rim comprises a rim body and a bent flange, and the bent flange is connected with the peripheral edge of one axial end of the rim body and extends in a bent mode; the spoke is arranged at one axial end of the rim, the axial inner surface of the spoke is attached to the first axial end face of the bent flange in a matched mode, and a first positioning hole is formed in the spoke. The first end of the positioning element is connected with the bent flange, and the second end of the positioning element penetrates through the first positioning hole and then is connected with the fastening piece so that the rim and the spoke can be connected in a fastened mode. The problems that in the prior art, a spoke and a rim of a wheel cannot be reliably locked before being welded, the installation precision of the spoke is reduced, and after the spoke and the rim are assembled, the contact area between the spoke and the rim is too small, and the spoke can not stably and reliably support the rim are solved.
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, the fixed connection between the spokes and the rim of the wheel is realized by welding. However, before the spokes are welded and installed on the rim, the rim and the spokes need to be placed in a predetermined relative position, and then The two are welded, and during this process, the two cannot be locked reliably, resulting in the possible displacement of the spokes and the rim during the welding operation, so that the coaxiality of the rim and the spokes cannot be guaranteed, and the spokes are reduced. Installation accuracy. [0003] In addition, after the rim and the spokes of the existing wheels are assembled, the contact area between the two is too small to ensure that the spokes provide stable and reliable support for the rim, and cannot ensure that the wheels have a reliable radial ...
