On wheel hub；Further buffering apron is equipped in transmission pin outer cover.
The utility model has the beneficial effects that replacing direct current generator and AC frequency conversion using the straight frequency conversion permanent magnet synchronous motor that drives
Asynchronous machine, the outer rotor special construction by directly driving frequency conversion permanent magnet synchronous motor, which designs directly to transmit Large Electric wheel, to be moved
Power eliminates this part of reduction gearbox, realizes compact-sized, and failure rate is low, and safeguards simple.Again because of the interior of outer rotor
Surface uses permanent magnet mechanism, and stator axis uses water-cooling structure, so good heat dissipation effect, power density is high, high-efficient.And vehicle
Weight is undertaken by the hub bearing, wheel hub and tire being sleeved on motor stator axis, and motor bearings does not undertake the weight of vehicle,
Motor own wt is only undertaken, the failure and wear rate of motor bearings are greatly reduced.
