In this programme, not rounded compromise face, i.e. outer mold surface are processed into hub motor shell part, hub inner lumen be processed into
Corresponding inner mold face, outer mold surface and inner mold face form Profile Connection, and Profile Connection carries out radial positioning, motor shaft to wheel hub
Bearing is installed between wheel hub wheel center hole, axially position is carried out to wheel hub by nut.Wheel hub wheel disc and wheel hub wheel rim
It is easy for installation for split-type structural.Bearing is arranged on motor shaft first, then wheel hub wheel rim and its inner mold face and motor
Shell outer mold surface is according to corresponding angle so that wheel hub wheel disc moves along motor shaft axis towards wheel hub motor direction, then
Put backing plate well and tighten nut.
The outstanding advantage that the technical solution of the utility model has is mainly reflected in the following aspects：
First, the utility model wheel hub transmits moment of torsion using Profile Connection.Profile Connection simple shape, convenient disassembly are tired
Labor intensity is high, and bearing capacity is high.
Second, the Profile Connection self-centering capability that the utility model uses is strong, improves wheel hub motor and is connected with wheel hub
The transmission accuracy and stationarity of system.
3rd, compared to the bolt connection of traditional wheel hub motor and wheel hub, the type face connection that the utility model wheel hub uses
Connect and eliminate stress concentration phenomenon, add the service life of wheel hub motor and wheel hub；
4th, the utility model wheel hub wheel disc and wheel hub wheel rim are split-type structural, are easy to the installation of motor internal；
5th, the utility model wheel hub transmits moment of torsion mainly by Profile Connection, and spoke can be done more frivolous, and wheel hub
Wheel disc has larger design freedom, disclosure satisfy that the multifarious requirement of wheel hub front pose.
