The specific embodiment
Below in conjunction with Figure of description and embodiment, the present invention is further described.
This Moped Scooter driver train, comprise housing 1, foot-driven lever 2, motor 3, retarder 4 and power coupling mechanism 5, foot-driven lever 2 is arranged in shell 1 body rotationally, the two ends of this foot-driven lever are connected with power coupling mechanism with the pedal of Moped Scooter respectively, and motor 3 is placed in housing and by retarder 4 and is connected with power coupling mechanism 5.
Retarder 4 is harmonic speed reducer, this harmonic speed reducer comprises the rigid wheel 41 with internal tooth, flexible gear 42 and middle part section are elliptoid producer 43, rigid wheel 41 is fixedly installed in housing, in the present embodiment, in fact rigid wheel 41 is integrated with housing, producer is arranged in housing rotationally, flexible gear is set in rotationally producer section by a flexible bearing 44 and is in elliptoid part, flexible gear makes it be ellipticity with producer generation deformation, the two ends that this flexible gear is corresponding with transverse end and the engagement of the internal tooth on rigid wheel, producer is connected with motor-driven, and mouth 421 and first one-way wheel of flexible gear 42 are in transmission connection.
Motor drives after deceleration by harmonic speed reducer, and the output shaft of flexible gear is connected by spline drived with the first one-way wheel, and the output shaft by the foot-driven lever being connected with stretcher through producer and retarder is connected with the second one-way wheel; When driven by power, the first one-way wheel drives ratchet twirl, and now the rotating speed of the first one-way wheel is faster than the second one-way wheel, and the second one-way wheel is done the rotation reverse with the first one-way wheel with respect to ratchet, now between the second one-way wheel and ratchet, skid, sprocket wheel is driven by motor completely; Vice versa, and when turning off motor, when manpower is ridden, the first one-way wheel skids, and now sprocket wheel is driven by manpower completely.
The S. A. of motor output shaft of the present invention and harmonic speed reducer is coaxial configuration, to improve the working condition of whole mechanism, in this patent, the outputting power of motor passes to harmonic speed reducer S. A. in the mode of coupling, the latter drives flexible bearing and flexbile gear rotation, and because the firm wheel of this mechanism is fixed, so the output speed of flexbile gear is 1/i times of motor speed, the reduction ratio that wherein " i " is harmonic speed reducer, moment of torsion has amplified " i " doubly simultaneously; The S. A. of this patent motor and foot-operated S. A. have adopted power coupling mechanism, and their motions are each other non-interference, and the power producing separately all can be exported by power coupling mechanism.
