Description

Electric bicycle shift position double-speed motor
Affiliated technical field
The utility model relates to a kind of motor, especially electric bicycle shift position double-speed motor.
Background technology
Electric bicycle has entered in the daily life as a kind of walking-replacing tool, progressively replaces bicycle.The motor that electric bicycle is in the market used has been generally the brush gearless motor, this motor motor can occur when climbing do not have force phenomenon, and electric bicycle when starting current ratio is bigger, power consumption is big, influence mileages of continuation, use the electric bicycle incompatibility of this motor to travel in the knob.
Summary of the invention
In order to overcome the deficiency that existing electric bicycle climbing is unable, the motor power consumption big, the electric motor starting electric current is big, the utility model provides a kind of and has hill gear and the shelves that travel, make the electric bicycle climbing easily, starting current is little, the electric bicycle of economize on electricity shift position double-speed motor.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric bicycle shift position double-speed motor, has wheel hub, end cap, end cap is fixedlyed connected with wheel hub, be provided with stator in the wheel hub, stator axis, rotor and power supply are passed a bridge, bearing and brush holder are housed on the stator, power supply is passed a bridge and is assemblied on the stator axis, be connected with the brush holder of stator, also be provided with central gear in the wheel hub, planet carrier, external toothing and clutch, planet carrier is assemblied on the stator axis and cooperates with central gear, external toothing and clutch engagement are installed on the end cap, and the stator axis end is provided with horizontal centre bore, and the middle part is provided with the mounting hole with axis normal, horizontal centre bore communicates with mounting hole, be equipped with push rod in the centre bore, push rod is outside equipped with the engage a gear device, and the engage a gear device is fixedlyed connected with push rod.
The beneficial effects of the utility model are, electric bicycle is easily climbed, little, the economize on electricity of electric motor starting electric current, and folk art term position easy switching, easy to operate, install simple.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of electric bicycle of the present utility model with shift position double-speed motor.
1. wheel hubs among the figure, 2. end cap, 3. stator, 4. stator axis, 41. centre bores, 42. mounting holes, 5. rotor, 6. power supply is passed a bridge, 7. bearing, 8. brush holder, 9. central gear, 10. planet carrier, 11. external toothings, 12. clutches, 13. push rods, 14. engage a gear devices.
Embodiment
As shown in Figure 1, a kind of electric bicycle shift position double-speed motor, has wheel hub 1, end cap 2, end cap 2 is fixedlyed connected with wheel hub 1, be provided with stator 3 in the wheel hub 1, stator axis 4, rotor 5 and power supply pass a bridge 6, bearing 7 and brush holder 8 are housed on the stator 3, power supply gap bridge 6 is assemblied on the stator axis 4, be connected with the brush holder 8 of stator 3, wheel hub 1 also is provided with central gear 9, planet carrier 10, external toothing 11 and clutch 12, planet carrier 10 are assemblied on the stator axis 4 and cooperate with central gear 9, and external toothing 11 cooperates with clutch 12 and is installed on the end cap 2, stator axis 4 ends are provided with horizontal centre bore 41, the middle part is provided with the mounting hole 42 with axis normal, and horizontal centre bore 41 communicates with mounting hole 42, is equipped with push rod 13 in the centre bore 41, push rod 13 is outside equipped with engage a gear device 14, and engage a gear device 14 is fixedlyed connected with push rod 13.
During work, when electric bicycle starting or climbing, the electric bicycle left hand is arranged on shelves at a slow speed to last manual shift device, this moment clutch seizure, the stator on the stator axis is in counter-rotating, the central gear transmission planet carrier drive external toothing on the stator turns round forward.When the electric bicycle cruising, rotate left hand last shift device, the shift device is arranged on the shelves that travel, at this moment, throw-out-of clutch, engage a gear device promote push rod stator are fixed, and outer wheel hub is changeed forward.
