Detailed Description
The utility model discloses a core lies in providing a split type wheel hub, can reduce cost of maintenance.
In order to make those skilled in the art better understand the technical solution of the present invention, the following will describe the split hub and the electric vehicle in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1A and fig. 1B, two axial measuring drawings of the split hub provided by the present invention are shown at two different angles, respectively; fig. 2 is a front view of the split hub provided by the utility model; the utility model discloses a split type wheel hub includes adopts split type rim 1 and spoke 2 that independently sets up, and spoke 2 includes pivot sleeve 21 and spoke 22, and spoke 2 is the integral type shaping structure, and pivot sleeve 21 rotates the suit on the axletree, and spoke 22 is equipped with a plurality ofly, shows in the figure taking five spoke structures as an example; the inner ends of the spoke shafts 22 are integrally fixed on the rotating shaft sleeve 21 and are distributed in a radial shape, namely the spoke shafts are arranged in a manner of dispersing around the rotating shaft sleeve 21 as the center, the outer ends of the spoke shafts 22 are in contact with the inner surface of the rim 1, the spoke shafts 22 are mutually overlapped with the rim 1, and the overlapped parts of the spoke shafts 22 and the rim 1 are relatively fixed through bolts.
The utility model discloses adopt split type structure setting with rim 1 and spoke 2 to can dismantle fixedly through the bolt, after rim 1 damaged with 2 one of them parts of spoke, can demolish the part of more renewing alone with it, do not need whole change wheel hub, reduce the cost of maintenance of wheel hub damage.
