The inner rotor motor is embedded in the groove of the wheel felloe, and the output shaft of inner rotor motor is connected with a central wheel in the planet gear reduction mechanism to drive the central wheel and is taken as the input of planet gear reduction mechanism; the planet carrier and spindle of the planet gear reduction mechanism are fixed on a stator shell, and its output gear ring is connected with the wheel felloe to transmit the power to the wheel felloe. The utility model has the advantages of low weight, high power density, and big output torsion, which lays a solid foundation for developing high-performance chassis system of vehicles driven by four-wheel wheel hub motors.
Description
Technical field
The utility model relates to a kind of Electric Motor Wheel structure of four-wheel drive fuel cell car, and is especially a kind of in limited wheel rim space, and integrated motor, planetary gear reducing mechanism and brake are the lightweight Electric Motor Wheel of one.
Background technology
The electric automobile of wheel hub electric motor driving at present mainly contains two types.A kind of is the motor that adopts the high speed internal rotor, and the epicyclic reduction gear unit that installs high speed reducing ratio between motor output shaft and wheel again additional reduces vehicle wheel rotational speed; Another kind then is to adopt the low speed outer rotor motor, and this kind motor need not any speed change gear and is directly installed on the rim for automobile wheel.The high speed inner rotor motor has that volume is little, light weight, cost is low and power density is high advantage, but it needs the step planetary gear gear.And the low speed outer rotor motor is simple in structure, and the former power density is lower, volume is bigger but compare.
Compare with the traditional combustion engine automobile, the drive system arrangements of electric automobile has greater flexibility.The electric motor car that the wheel limit drives pattern has changed traditional centralized driving mode, is driven respectively on the wheel limit by four independent Electric Motor Wheel.Like this, the mechanical output that it has omitted orthodox car again to the transmittance process on wheel limit, has high efficiency advantage from the gearbox to the semiaxis.Particularly because the actuating force of each wheel is all directly accurately controlled, can and realizes driving automobile chassis dynamics Controlling functions such as anti-skidding, braking anti-lock and Stability Control easily, and can obtain splendid dynamics Controlling performance.Therefore taking turns limit driving pattern is the feasible Drive for EV form of a kind of advanced person.But Electric Motor Wheel has increased parts such as motor, reducing gear on the wheel limit, and the nonspring carried mass of automobile is increased, and will cause the ride comfort variation of automobile, and it is big that the dynamic loading of wheel becomes.
Summary of the invention
The technical problems to be solved in the utility model is that the inner-rotor type integrated electric wheel construction of four-wheel drive the fuel cell car light weight, the power density that need are big, output torque is big, and a kind of gear ring output type internal rotor integrated electric wheel construction is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of gear ring output type internal rotor integrated electric wheel construction comprises wheel rim, drum brake or disk brake, inner rotor motor, planetary gear reducing mechanism.
Inner rotor motor is fitted in the groove of wheel rim, and the inner rotor motor output shaft is connected, directly drives sun gear with sun gear in the planetary gear reducing mechanism, as the input of planetary gear reducing mechanism; The planet carrier of planetary gear reducing mechanism and axle are fixed on the stator case, and the output gear of planetary gear reducing mechanism is connected with wheel rim, outputs power to wheel rim.
Gear ring links to each other with wheel rim through spring pivot.Inner rotor motor is fixedlyed connected with suspension by the inner rotor motor housing.Drum brake is fixedlyed connected with wheel rim with bolt.The brake disc of disk brake is fixedlyed connected with wheel rim.
The beneficial effects of the utility model are: integrated electric wheel construction of the present utility model, can use disc type or drum brake, and have light weight, power density is big, output torque is big advantage; In addition, transmission of power approach and force-bearing situation are reasonable, each parts integrated level height, and compact conformation has effectively been realized the lightweight of integrated electric wheel construction.As novel integrated Electric Motor Wheel, this structure can directly apply to the electric automobile that wheel hub motor drives.Establish important basis for exploitation based on four-wheel wheel hub motor driven vehicles high-performance chassis system, had very strong engineering specific aim, therefore had very important actual construction value.
