Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the present invention is further described.
This Moped Scooter driving mechanism, including housing 1, foot-driven lever 2, motor 3, decelerator 4 and power coupling mechanism 5, foot-driven lever 2 is rotatably arranged in shell 1 body, the two ends of this foot-driven lever are connected with the pedal of Moped Scooter and power coupling mechanism respectively, and motor 3 is placed in housing and is connected with power coupling mechanism 5 by decelerator 4.
The first one-way wheel 52 and the second one-way wheel 53, ratchet 54 that power coupling mechanism 5 includes sprocket wheel 51, is rotatably provided in housing, ratchet is rotatably arranged in housing, and the inner ring of the outer ring of ratchet and sprocket wheel is fixing is connected, first one-way wheel the 52, second one-way wheel 53 is coaxially rotatablely arranged in ratchet, the outer ring of the first one-way wheel and the second one-way wheel is respectively arranged with ratchet 23, is provided with two relative with the ratchet group unidirectional groove of the opposite sex (not shown in FIG.) in ratchet;Decelerator 4, foot-driven lever 2 are connected with first one-way wheel the 52, second one-way wheel 53 respectively.The middle part of the first one-way wheel and the second one-way wheel is respectively equipped with the first driving hole 521 and the second driving hole 531, and the internal diameter of the first driving hole is more than the second driving hole.It is respectively arranged with spline 32 in first driving hole and the second driving hole.Generator is internal axially hollow, and foot-driven lever is in transmission connection through generator and the first one-way wheel.The side of the first one-way wheel is provided with the end cap 55 that the first one-way wheel, the second one-way wheel are axially positioned.
Decelerator 4 is harmonic speed reducer, this harmonic speed reducer includes the rigid wheel 41 with internal tooth, flexible gear 42 and middle part section are elliptoid generator 43, rigid wheel 41 is fixedly installed in housing, in the present embodiment, rigid wheel 41 is actually integrated with housing, generator is rotatably arranged in housing, it is in elliptoid part that flexible gear is rotatably sleeved on generator section by a flexible bearing 44, flexible gear deforms upon so that it is ellipticity with generator, this flexible gear two ends corresponding with transverse end are engaged with the internal tooth on rigid wheel;Generator is connected with motor-driven, and the outfan 421 of flexible gear 42 and the first one-way wheel are in transmission connection.
After motor is driven deceleration by harmonic speed reducer, output shaft and first one-way wheel of flexible gear are connected by spline drived, output shaft and second one-way wheel of the foot-driven lever traverse generator being connected with pedal and decelerator are connected;When driven by power, first one-way wheel drives ratchet quick rotation, 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 does the rotation reverse with the first one-way wheel relative to ratchet, now skidding between the second one-way wheel and ratchet, namely 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 motor output shaft of the present invention and the rotating shaft of harmonic speed reducer are coaxial configuration, to improve the working condition of whole mechanism, in this patent, the output power of motor passes to harmonic speed reducer rotating shaft in a coupled manner, the latter drives flexible bearing and flexbile gear to rotate, and owing to the just wheel of mechanism is fixing, therefore the output speed of flexbile gear is 1/i times of motor speed, the speed reducing ratio that wherein " i " is harmonic speed reducer, moment of torsion is exaggerated " i " times simultaneously;The rotating shaft of this patent motor and foot-operated rotating shaft have employed power coupling mechanism, and they motions each other are non-interference, and the power each produced all can be exported by power coupling mechanism.
