[0010] Further description will be made below in conjunction with accompanying drawings.
[0011] exist figure 1 , figure 2 , image 3 , Figure 4Among them, in order to adapt to the driving mode of the front wheel of the engine or the driving mode of the rear wheel of the engine of the new energy vehicle, the axles of the front and rear four wheels of the new energy vehicle are all selected as hollow axles with a central half shaft, because the new energy vehicle disclosed in the present invention The engine is set at the front wheel position, so the left and right front wheels are driving wheels, and the left and right rear wheels are driven wheels. The models of the left front wheel, right front wheel, left rear wheel and right rear wheel of new energy vehicles are the same, and the four wheels 4 disc brakes and 4 rim motors are respectively installed inside, and rim motors are set in the remaining space between the disc brakes and the rim. The models of the 4 disc brak...

The invention discloses a new energy automobile rim motor. The rim motor is positioned between a fan-shaped brake and the inner circle of a rim; the fan-shaped brake is located on the inner circumference of an annular disc brake piece. The outer circumference of the annular disc brake piece is connected with a rim rotor; a permanent magnet annular surface of the rim rotor and an annular surface ofa disc-shaped frame stator form a large-area driving magnetic field, and a low-speed brushless permanent magnet motor of a radial magnetic circuit is formed; the rim rotor is fixed to the inner circle of the rim and rotates along with a wheel; the disc-shaped frame stator is fixed to the right side of the disc-shaped frame and stays still; the rim motor directly drives the wheel, and during braking, the rim motor is reversely charged; the annular disc serves as the rim motor rotor and the disc brake piece of the brake and mutual affection is avoided; the four rim motors drive four wheels in adispersed mode, power of the four rim motors is organically matched with power of an engine, reasonable matching of multiple kinds of power is achieved through artificial intelligence control, and the new energy automobile can work in the best energy-saving and environment-friendly state.
Description
technical field [0001] The invention relates to a motor drive device of a new energy vehicle, specifically a wheel rim motor of a new energy vehicle. Background technique [0002] At present, in the field of motor drive technology for new energy vehicles, there is a wheel-side motor integrated in the wheel that directly drives the wheel. It has the advantages of not needing to change the structure of the engine drive system and having no mechanical transmission loss. Widespread concern. A patent application with the application number "2018106255731" titled "Disc Wheel Motors for New Energy Vehicles" discloses a technical solution in which 4 disc wheel motors are installed in 4 wheels respectively. Its disadvantages The difference is that the axles of the four wheels are solid axles, and the centers of the four disc-type wheel motors are not provided with a central half shaft, so that the power of the engine cannot be coupled to the driving wheels, so that the disc-type whe...
