The inner wall of wheel rim；It has following advantages:
1, magnetic steel ring and the assembly intensity of remaining motor component are ensured by interconnecting piece, while reduces the thickness of magnetic steel ring
Degree, reduces the weight of entire wheel hub；
2, while loss of weight, also stand-by motor radiates the toroidal cavity between annulus main body and wheel rim inner wall, makes to have leisure
Gas can be directly over the outer wall of magnetic steel ring, promote the heat dissipation effect of motor, to improve the working efficiency of motor；
3, it is only overlapped by interconnecting piece between magnetic steel ring and wheel rim, when wheel rim is by external force collision, which has very big
Probability is not directly transferred to inside motor so that hitting the concussion generated, it is ensured that motor the operation is stable at toroidal cavity；
4, the specification of interconnecting piece, which can according to need, is slightly adjusted, so that the magnetic steel ring of a specification can adapt to phase
The different wheel rims of nearly specification；
5, cost is reduced；
6, magnetic steel ring setoff installation is in wheel rim, the soldered of interconnecting piece and wheel rim inner wall be arranged in magnetic steel ring closer to
Side in the middle part of wheel rim, the design is so that wheel rim and interconnecting piece welding are simpler, but also remaining part is more easily installed.
