Background technology
The truck-loading scheme of commercial car and large and medium-sized passenger car is mostly the multiple speed transmission with driving motor currently on the market,
And small passenger car adds single speed reducing ratio system using driving motor more or uses direct driving motor system.Automobile is in actual travel process
In, state is changeable, as starting accelerate and climbing during need slow-speed of revolution high torque, when smooth-ride, needs the low torsion of high rotating speed
Square.Single speed is than speed change gear and the drive system without speed change gear not only increases the difficulty of full-vehicle control, more transports motor
Row economy reduces, and vehicle continual mileage declines.On the other hand, small passenger car because its interior space it is limited, it is difficult to arrangement is existing
Some motors add speed transmission scheme.The characteristics of pure electric automobile industry development is advanced by leaps and bounds in recent years, its zero-emission is fitted
Energy saving and environmentally friendly development main trend is answered, wheel hub motor technology has become automobile industry and has much perspective field.
Chinese patent application file CN1674413A discloses a kind of " wheel hub motor ", and it includes the motor master being mutually fixedly connected with

End cap and stator right end cap, by the left and right end cap spiral-lock of stator in it by the stator with coil windings, magnet steel, rotor core
The motor of composition, the motor main casing and motor cover that motor power is fixed with one through planetary gear speed reducing mechanism driving rotate；The row
Star reducing gear is two-stage planetary reduction mechanism, by driving gear of the movable set on main shaft, the peace engaged with driving gear
Planetary gear in planet axis, engage with carrier gear, internal gear at the same time with the coaxial gear III of planetary gear, driving and
The motor cover and motor main casing that internal gear is connected rotate, and the rotor core is equipped with solid with the driving gear place of being combined
The rotor bushing being scheduled in rotor core, between the rotor bushing and driving gear be equipped with outside the clutch of rotor bushing close-fitting
Ring, roller rolling retainer, roller, the roller clutch of reed composition.The hub motor structure is complex.
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art, there is provided a kind of improved wheel hub motor system, it is described
Wheel hub motor system includes end cap, circuit integrated system, capacitance ring, default subsystem, bearing, outer rotor system, casing, braking
