Above-mentioned ratchet very heavy 53 or ratchet very heavy 54 are provided with one separately at least, so ratchet very heavy 53 is uniformly distributed with and is symmetrical set 3, ratchet very heavy 54 and is uniformly distributed with and is symmetrical set 2, it is the optimal way in the utility model.All or part ofly on the outer surface of, ratchet very heavy 54 very heavy 53 reduce noises by noise abatement material 52 when adhering to fixedly on noise abatement material 52 (or adhering to fixedly noise abatement material on the ratchet toothed surface in the very heavy correspondence of ratchet) and the very heavy ratchet toothed surface of ratchet the slide relative contact in correspondence at the ratchet of processing with metal material; Non-cohesive noise abatement material on the outer surface of perhaps very heavy 53, ratchet very heavy 54 and directly using at ratchet; Scribble lubricant (grease or thin oil) on the outer surface of, ratchet very heavy 54 very heavy 53 at ratchet; Noise abatement material 52 is rubber, polyurethane, plastic cement, nylon, resin or engineering plastics; Wherein, adopting elastomeric material is the optimal way in the utility model.

Above-mentioned one-level planetary gear 31 or secondary planet wheel 27 adopt metal and nonmetal compound gear (or to adopt nonetallic gear fully; Can also adopt metal gear fully); One-level planetary gear 31 in the utility model or secondary planet wheel 27 are preferred steel material and the integrated compound gear of nylon material; Like this, the steel material of gear part can be resisted big overload impact, and the nylon material part of gear can fully show its resistance to wear; Thereby reduce the spoilage of gear, raising CD-ROM drive motor quality also increases the service life.

The profile of above-mentioned CD-ROM drive motor shell 12 adopts tooth-shape structure; So both can reduce CD-ROM drive motor weight; Reduce cost; Be convenient to again and the fixing assembling of electric bicycle car load, the fixed screw holes of left end cap 42 and right end cap 18 is set on the profile profile of tooth of CD-ROM drive motor shell 12 and is fixedly connected by screw 5.Between CD-ROM drive motor shell 12 and pilot 43, seal 6 37 is set; Be provided with on the corresponding CD-ROM drive motor shell 12 of variable-speed motor inner chamber notes, oil-draining locknut hole 57 (annotate, oil-draining locknut hole 57 directly in the feeding variable-speed motor inner chambers and 1 or upper and lower 2 notes, oil-draining locknut hole 57 can be set); Like this; Help injecting lubricant, make the variable-speed motor parts can obtain good lubricating, increase the service life.

During use; CD-ROM drive motor gets electric, and rotor 35 rotates, after variable-speed motor is realized two stage speed change by secondary planet wheel support 16 outputting powers; At this moment; Be arranged in secondary planet wheel support 16 pawl slots ratchet very heavy 53 spring 51 effect rise with β angle wing down and with output shaft 23 on the engagement of ratchet external tooth, thereby the drive 26 that drives on the output shaft 23 rotates, and then the driving electric bicycle advances.Because the ratchet profile of tooth of the first arrangement of clutch outer ring on the output shaft 23 and the ratchet profile of tooth setting in the opposite direction of the second arrangement of clutch inner ring; Make the ratchet very heavy 54 of output shaft 23 in the first arrangement of clutch inner ring 24 and pawl slot thereof slide one-directional rotation; Make foot-operated axis 1 motionless; Even can make counter-rotation with respect to output shaft 23, CD-ROM drive motor is in complete motoring condition.

When the CD-ROM drive motor outage; Manpower is foot-operated to be driven when riding axis 1 rotation; The ratchet very heavy 54 that is arranged in the pawl slot of the first arrangement of clutch inner ring 24 rises with α angle wing down and meshes with ratchet internal tooth on the output shaft 23 in spring 50 effects; Thereby the drive 26 that drives on the output shaft 23 rotates, and then foot-operated the advancing of driving electric bicycle manpower.At this moment; The ratchet very heavy 53 that is arranged in secondary planet wheel support 16 pawl slots falls; Output shaft 23 is done the unidirectional rotation of sliding with respect to the outer ring of second arrangement of clutch of secondary planet wheel support 16, makes that manpower is foot-operated to be separated with CD-ROM drive motor fully, realizes the electric bicycle non-resistance function of riding.

For this reason, can also realize that CD-ROM drive motor and manpower assisted pedal stroke drive the electric bicycle driving functions simultaneously.Particularly electric bicycle is when starting, climbing perhaps have only the power-assisted driving functions; Adopt the foot-operated power-assisted that drives of drive motor and manpower to go; Starting, climbing capacity and the reduction that can the improve electric bicycle greatly electric current that goes, saves energy prolongs mileages of continuation and useful life.
