Specific embodiment
Presently in connection with specific embodiment, the present invention is further illustrated.These attached drawings are simplified schematic diagram only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
Embodiment one
As shown in Fig. 1 Fig. 2, a kind of mobile mechanism based on hub motor, including hub motor and power-off braker.Wheel hub electricity
Machine includes rotor hub and stator axis, and the rotor hub includes wheel shell and side cover, and the side cover center opens up axis hole, described
Side cover lateral wall extends outward to form brake axle along axis hole；The stator axis inner end is rotatably assorted with wheel shell inner wall, the stator
Axis outer end is successively from side cover to be pierced by the rear and setting that fixes in brake axle；Specifically, stator axis outer end and the fixed company of mounting plate
It connects.
Power-off braker includes pedestal, magnetic yoke, armature, brake disc and connecting bushing, and entire power-off braker passes through seat
Body is connected and fixed with mounting plate, and connecting bushing is fixedly connected with brake axle, is connected between connecting bushing and brake disc using spline；
Magnetic yoke is fixed in pedestal, and armature is between brake disc and magnetic yoke, and when magnetic yoke work once electrified, absorption armature is left
