This turning cylinder 56 is when the direction of arrow is rotated, and satellite gear 61c utilizes this rotation to begin to rotate, and simultaneously and rotating cylinder 62, turning cylinder 56 crimping, is moved into the angle that is sandwiched angle of wedge degree M.Thereby, other 2 satellite gear 61a, satellite gear 61b also with turning cylinder 56 crimping, with pin 60a, the pin 60b be that the center begins rotation.And, by 3 satellite gears 61 and turning cylinder 56 crimping, contacting with the periphery of satellite gear 61, rotating cylinder 62 just utilizes and the friction force of satellite gear 61 begins to rotate towards the direction of arrow.This state continues during greater than the rotating speed of output shaft 63 at the rotating speed of turning cylinder 56.

Next illustrates the situation of the rotating speed of trailing wheel 11 greater than the rotating speed of motor 55.As shown in Figure 1, at the state of satellite gear 61c crimping, the rotating speed of trailing wheel 11 is during greater than the rotating speed of motor 55, and rotating cylinder 62 changes sooner than turning cylinder 56, because of not having the pin that becomes 6 at center at satellite gear 61c, satellite gear 61c begins to move to the direction of the crimping of breaking off turning cylinder 56 and rotating cylinder 62.Then, when turning cylinder 56 and not crimping of satellite gear 61c, because of other satellite gear 61a, 61b also with turning cylinder 56 not crimping, can't pass to rotating cylinder 62 from the power of motor 55, the moving of this satellite gear 61c makes the transmission of cutting off power.That is, this satellite gear 61c has the function of folk prescription to power-transfer clutch.Therefore, during greater than the rotating speed of motor 55, the load that motor 55 can not become trailing wheel 11 to rotate can be travelled smoothly at the rotating speed of trailing wheel 11.

Secondly, according to the structure of detailed description satellite gear speed reduction gearing 59, motor 55 and the belt pulley 66 of figure.

The 89th, with so that the chimeric bearing of the turning cylinder 56 of this motor 55 is located at this satellite gear speed reduction gearing 59, embed these bearings 89 by making turning cylinder 56, turning cylinder 56 can be fixed on satellite gear speed reduction gearing 59 and order is rotated.Can make again and rotate smoothly.At present embodiment, on the input mechanism of input turning cylinder 56, use bearing, but so long as link all can of turning cylinder 56 and satellite gear speed reduction gearing 59.

The 90th, be located at the connecting element at periphery 2 places of the lid 64 of this satellite gear speed reduction gearing 59, this connecting element 90 is by the adapter plate of being pushed down from the top by this lid 64 91 and run through the screw 92 that shells of these adapter plate 91 backs and motor 55 screw togather.Utilize this connecting element 90 to stop this lid 64 to rotate.

At above-mentioned structure, the tension of 0 concentration of ions detecting part 67 action when assembling being described according to Fig. 2 and Fig. 3.

When satellite gear speed reduction gearing 59 is installed, make turning cylinder 56 embed bearing 89.Then, utilize this connecting element 90 fixedly the preceding elder generation of lid 64 belt 67 of back segment belt pulley 72 is installed.At this moment, the turning cylinder of Yin Mada 55 56 and defeated Hong the axle 63 of being located at lid 64 are in eccentric position, and making lid 64 be that move on center edge off-centre limit with the turning cylinder 56 of motor 55, belt 67 draw the tightest position, utilize this connecting element 90 to fix this lid 64.What represent this state is, to the moving of solid line position, utilizes connecting element 90 fixing by the state of 2 chain lines shown in Figure 3 when lid 64 is positioned at solid line position.This fixing means is the fixing lid 64 of screw 92 that has run through adapter plate 91 by locking, but does not need just tightening belt 67 of part such as tension strap wheel.

Secondly, according to the power transmission of Fig. 9 explanation at above-mentioned structure.

At first, manpower driving system is described, by the manpower of pedal 5 input, sprocket wheel 36 through chain 17 passes to after, after change-speed box 34 speed changes, make packing ring spring 43 crooked and the rotating side shell 31 that passes to back segment belt pulley 72 is rotated and driving.

Next illustrates electric drive system, with the bending of the above-mentioned packing ring spring 43 of moment of torsion detecting part 88 detectings, as the size of manpower propulsive effort, by detect this signal with it as manpower propulsive effort signal, input control circuit plate 82.Then, the drive signal of output motor 55, as make size become and the cooresponding electric driving force of manpower propulsive effort signal imported as CD-ROM drive motor 55.Pass to back segment belt pulley 72 via satellite gear speed reduction gearing 59, belt pulley 66, belt 67 and the manpower propulsive effort drives trailing wheel 11 together from the propulsive effort of the defeated ratios of motor 55

At present embodiment, in the end a section belt pulley 72 is provided with belt 67 with transfer motion power, but also can be without belt 67, and gear is set, become adjust nibbling of gear and gear contain,

As noted above, because of the clutch equipment of the unidirectional propulsive effort of a transmission is set between turning cylinder 56 and output shaft 63, has can have concurrently reductor and from contain apparatus, the part number tails off, becomes light and small-sized effects such as structure.

Again, because of reductor uses satellite gear speed reduction gearing 59, except reductor become small-sized, 61c has the function of destage device because of this satellite gear, except light and small-sized, because of making 2 kinds of functions, have the effect that the part number tails off, also controls price with a part is intact.

Because of using these power drives at battery-driven car, at the rotating speed of motor 55 during,, has the effect that load is little and can travel smoothly in this situation because of having the rotation of cutting off drive wheel and the powerdriven function of motor 55 greater than the rotating speed of drive wheel again.
