Driving motor-contained wheel hub system for pure electric automobile

The invention relates to a driving motor-contained wheel hub system for a pure electric automobile. The wheel hub system comprises a wheel hub and a brake disc. The wheel hub system is characterized in that a coaxial outward-rotating wheel hub permanent magnet brushless direct current motor is installed on a cavity formed in the inner side of a wheel rim; a motor housing (4) is fixedly connected with the wheel rim via a bolt; a wheel hub motor aluminum core is installed in the motor housing; the wheel hub motor aluminum core is connected with a wheel hub motor shaft; one side of the motor housing is equipped with a motor end cover; and two ends of the wheel hub motor shaft are respectively connected with the motor housing and the motor end cover via bearings. The driving motor-contained wheel hub system for the pure electric automobile is advantages in that the wheel rim works as an installation position of the motor and the wheel rim, a tire and a brake system are integrated, so components of a fuel engine, a gearbox, a clutch, a transmission shaft, a back axle differential case, an oil tank and a cooling water tank system necessary for a traditional automobile can be avoided; the driving motor-contained wheel hub system has high manufacturing universality, cost controllability, maintenance convenience and long distance driving performance; the wheel hub system has high cost performance; and possibility for large scale industrial production is provided.
