Abstract
The utility model relates to an outer rotor planetary gear reducing motor, which adopts the motor with an outer rotor structure, a sun gear of a planetary gear reducer is arranged on an outer rotor of the motor, a planet carrier and a gear ring of a planetary gear are fixed on a wheel hub. The motor outer rotor drives the sun gear to rotate, so as to drive the planetary gear; as the planet carrier and the gear ring are fixed on the wheel hub, the utility model can further drive the wheel hub to rotate. The utility model has simple structure and higher driving efficiency.
Description
Affiliated technical field
The utility model relates to a kind of external rotor planetary gear reduction speed motor, and this reducing motor adopts the planetary gear speed-reduction technology.
Background technology
Electric motor car is to rely on wheel hub motor that power is provided, because the rotating speed of wheel hub should not be too high, causes the wheel hub motor efficient of direct driving lower, and moment is less.In order to improve the efficient of electric motor car, improve the load capacity of electric motor car, the back output of need motor slowing down, and the reducing motor that is used for electric motor car now is that axis drives, and by chain drive the efficient of electric motor car is reduced again.
Number of patent application: 200620044082.0 have proposed wheel hub shape harmonic gear reductor, because the harmonic gear cost is higher, application has certain degree of difficulty.
Summary of the invention
In order to overcome the deficiency of existing reducing motor, the utility model proposes a kind of solution of external rotor planetary gear reduction speed motor.
Scheme of the present utility model is to adopt the motor of outer-rotor structure, on the external rotor of motor, be provided with planet-gear speed reducer sun gear, planetary planet carrier and gear ring are fixed on the wheel hub.Motor outer rotor drives sun gear and rotates, and drives planetary gear, because planet carrier and gear ring are fixed in wheel hub, thereby drives the wheel hub rotation.
The utility model can improve the efficient of reducing motor, is applied in the electric motor car, can improve the distance travelled of electric motor car.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the detail of construction of external rotor planetary gear reduction speed motor
Fig. 2 is the design of part detail drawing that combines the motor outer rotor of sun gear
Fig. 3 is equipped with among planetary wheelboss part structure chart Fig. 1 with planet carrier and gear ring
1. wheel hub shell, 2. planetary gear, 3. motor outer rotor, 4. external rotor magnet steel, 5. internal stator iron core, 6. inner stator coil, 7. fixed central spindle.
Embodiment
In the detail of construction of Fig. 1 external rotor planetary gear reduction speed motor, external rotor magnet steel 4 is bonded on the motor outer rotor 3.One end of motor outer rotor 3 is provided with sun gear, as shown in Figure 2.Motor outer rotor 3 rotates when inner stator coil 6 energisings by the bearing location at two ends.Wheel hub shell 1 is provided with planet carrier and gear ring, planetary gear 2 by bearing fixing on planet carrier, as shown in Figure 3.Planetary gear 2 and gear ring and the engagement of the sun gear on the motor outer rotor 3 taken turns on the hub shell 1.During the sun gear rotation, rotate by planetary gear 2 driven wheel hub shells 1.Fixed central spindle 7 is fixing, and wheel hub shell 1 is by the bearing location at two ends, with wheel hub rotation mode carry-over moment.
