New description: [New technical field] The electric self-create is related to the deceleration of electric bicycles, especially the harmonic deceleration drive used in driving. [Prior Art] In terms of electric motors, electric motors are classified into three categories, namely, high-speed motors, medium-speed motors, and low-speed electric motors. The higher the rated speed, the smaller the volume, the heavy-duty, and the electric The lighter, more efficient, the lower the cost, but generally electric bicycles operate at low speeds, such as < The motor needs a matching reducer, the reduction ratio of the reducer, the speed of the door speed, and the efficiency 'cost is the decisive factor of the performance and price of the bicycle driver. Most of the electric bicycles use the low speed motor directly (1) to catch the mechanism, which has low technical content and high efficiency. Low, high cost two: machine = heavy. In recent years, electric bicycles have adopted a large number of medium-speed motors, and the performance of the gear = deceleration has improved. But at present, we are looking at domestic and foreign electric self.

This creation is suitable for electric bicycles driven by high-speed motors. It is compact, small in size, light in weight, small in speed and loud, and high in efficiency. Human and electric power can drive bicycles separately or together. [Embodiment] Hereinafter, each embodiment of the "electric bicycle proof wave reduction drive" of the present invention will be described. Please refer to the accompanying drawings, but the actual configuration and the method adopted do not have to completely conform to the described contents. The skilled person will be able to make various changes and modifications without departing from the actual spirit and scope of the present invention. Please refer to Figure 1 and Figure 2. Among them, Tubu is a schematic diagram of the structure of the electric wave deceleration driver of the electric bicycle; Fig. 2 is a schematic structural view of the single bidirectional bearing used in the creation of the electric bicycle harmonic reduction drive. . The electric bicycle harmonic reduction drive of the present invention comprises a bicycle center shaft 9, a sprocket 8 and a drive motor 2, and further comprises a driver housing 丨, a single bidirectional bearing 7 and a harmonic generator disposed in the harmonic reducer housing 3 4. The harmonic flex wheel 5 and the harmonic rigid wheel 6, the driver housing 丨 is sleeved with the two ends of the harmonic reducer housing 3, and the driving motor 2 is disposed in the driver housing 1 The harmonic generator 4, the motor rotor 21, and the motor stator 22 are sequentially set in the middle shaft 9, and the harmonic flex wheel 5 and the harmonic rigid wheel 6 are sequentially set on the outer ring of the harmonic generator 4, The harmonic wheel 6 is fixed in the harmonic reducer housing 3, and the single bidirectional bearing 7 is set on the middle shaft 9 and is located at the side of the harmonic reducer housing 3, and the single bidirectional bearing 7 Pack 5 M434858 includes inner ring turntable 71, middle turntable 奘e, f meat fixed wire and outer ring turntable 73, and then coaxially set 'the inner ring turntable 71 盥 thousand meat κι Λ抡, day 1 turntable 72 between the interval There are a plurality of inner ring protrusions 74, and the middle ^ ^ ^ ^ ^ disk 72 and the outer ring turntable 73 are spaced apart The right outer ring protrusion 7 5 75 is curved at both ends and protrudes toward each other. The inner ring protrusion 74 and the protruding end of the outer ring protrusion 75 are oppositely disposed. The inner ring protrusion 74 and the outer portion a ring-bump corbel wheel 5, the middle (four) 72H inner ring turntable 71 is connected to the said sprocket 8, the driving electric vehicle, the material ring turntable 73; ^ ^ electric machine 2, harmonic generation The device 4, the harmonic flex wheel 5, the syndrome wheel 6, the single turn & dry and coaxially set to the bearing 7 and the sprocket 8. Further, the above-mentioned driving electric drafter 2 can adopt a brushless high-speed motor, and the motor rotor 21 is directly fixed on the outer ring of the δ white wave generator 4 to constitute an overall 'the harmonic flexible wheel 5 and the harmonic generation cause 4 Between the harmonic soft wheel 5 and the s-wave reduction and the body 3 are respectively 五 (5) red a ▲ ^ The soil J is connected by the bearing support and simultaneously runs on the bicycle center shaft 9. When the driver is in operation, the driving motor 2 is powered by a battery (not shown), and the power is transmitted to the harmonic flex wheel 5 via the harmonic generator 4, and the harmonic flex wheel 5 rotates in the wave wheel 6 and drives The force is transmitted to the inner ring turntable 71 of the single bidirectional bearing 7, and the rotational speed of the drive motor 2 is transmitted to the inner ring turntable η of the single bidirectional bearing 7 via the harmonic generator 4 1 corbel 5 and the harmonic wheel 6 with a large reduction ratio Therefore, it is suitable for driving the high-speed drive motor 2 for the electric bicycle. When the drive motor 2 is driven, the inner ring turntable 71 of the early two-way bearing 7 is rotated to cause the inner ring projection 74 to stand up, and the intermediate turntable 72 is rotated. The bicycle is driven by the intermediate turntable 72. At this time, the outer ring projection 75 between the intermediate turntable 72 and the outer turntable 73 is inclined, and the outer turntable 6 M434858 73 is not rotated, and the bicycle is separately driven by the drive motor 2; 8桉鲳 桉鲳 过 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按 按As drive The motor 2 loses power and stops running, the human egg moves... the force can still drive the outer ring turntable through the sprocket 8 to drive the bicycle forward, at this time for the human to drive alone; and the human...the wheel 8 rotates in the reverse direction, the outer ring The slanting outer ring turntable 73 of the bump 75 cannot drive the intermediate turntable 72 to rotate. The single-direction bidirectional bearing 7 adopts the inner ring protrusion 74 and the outer ring protrusion 75 to transmit the driving force, which is an up-type transmission, which avoids the defects of the pawl and the ratchet structure impacting by the prior art. The service life of the two-way bearing 7 reduces the noise during the transmission process and ensures the normal doubt of the bicycle. At the same time, the drive has a compact structure and a large reduction ratio, and can be all mounted on the center axis of the bicycle, which reduces the weight and volume of the bicycle, effectively improving the driving efficiency of the bicycle. In summary, the creation of the "electric bicycle wave reduction drive" is to use the high reduction ratio of the spectral generator of the present invention to decelerate the high speed of the high speed drive motor to a low speed suitable for use. The high reduction ratio is caused by the (four) wave generated between the harmonic soft wheel and the harmonic wheel. After that, since the wave wheel is connected to the inner ring turntable of the single bidirectional bearing, the rotation of the high speed motor is transmitted to the single bidirectional bearing. The inner ring turntable is then transmitted to the intermediate turntable through the inner ring bumps, thereby outputting the rotational force to the bicycle wheel so that the bicycle advances. The wave generator of this creation is small in size, light in weight, and high in reduction ratio. It can completely replace the conventional planetary gear reduction. It can also be obtained through the combination of the high-speed motor and the spectral generator of the present invention. 'The low-speed motor used in this way, through the application of this creation, the cost of the red-red bicycle can be reduced, the weight is also reduced, and the structure is also simplified' so the surface can not only promote sales due to the cost reduction, consumers 4 s , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Environmental protection.
