  • Patent number: 10814670
    Abstract: A low-speed vehicle wheel assembly includes a rim, at least three spokes, connectors, a central bearing seat, and bearings. Outer ends of the spokes are fixedly connected to an inner side wall of the rim through the connectors, respectively. Inner ends of the spokes are fixedly connected to an outer wall of the central bearing seat. The bearings are fitted in bearing holes of the central bearing seat, respectively. Because the rim and the central bearing seat are independent components, each component can be made with an independent mold and assembled according to the diameter of the wheel. The cost of the mold is lower, and the components are more versatile.
