2The axle rotation is revolved round the sun around the O axle again simultaneously.
Described each planet wheel O
2Be connected with bearing on the axle.
The working principle that the utility model is applied to kick the formula bicycle is as follows:
When first foot treadle of kicking the formula bicycle is kicked forward, at first drop first wire rope 5, make the chock 12 of winning around O
3The stop to tie-rod 4 is removed in the axle rotation; When if wire rope 5 is continued to drop forward, tie-rod 4 is just driven and is rotated counterclockwise around the O axle, and tie-rod 4 is rotated counterclockwise, and passes through O on the one hand
2Axle makes planet wheel 3 around O
2Axle rotation counterclockwise, planet wheel 3 is revolved round the sun counterclockwise around the O axle, when planet wheel 3 rotates counterclockwise, by stirring of tooth, make override type gear 8 clockwise rotate again, override type gear 8 drives passive live axle 9 (bicycle rear axle) and turns clockwise, and just drives bicycle and travels forward.
When first wire rope 5 that rotates around tie-rod 4 moves to certain distance and comes to a halt, driven shaft (bicycle rear axle) still continues rotation according to inertia, but because override type gear 8 adopts is the override type gear, so passive live axle can't drive override type gear 8 and rotate counterclockwise; When first wire rope 5 comes to a halt, first spring 14 begins to shrink makes tie-rod 4 turn clockwise, driving override type gear 8 by planet wheel 3 is rotated counterclockwise, because override type gear 8 is override type gears, so override type gear 8 is rotated counterclockwise and can't drives passive live axle 9 and be rotated counterclockwise, that is to say that driven shaft still continues to turn clockwise, drive bicycle and travel forward.
When tie-rod 4 after turning back to reset condition under the effect of first spring 14, first chock 12 turns back to original position and again tie-rod 4 is limited under the effect of first torsion spring 16, tie-rod 4 has just been finished a two-way process like this.
When the crus secunda pedal of kicking the formula bicycle is kicked forward, at first drop second wire rope 6, make second chock 13 around O
3The stop to ring gear 7 is removed in the axle rotation; When if wire rope 6 is continued to drop forward, ring gear 7 is just driven and is rotated counterclockwise around the O axle, and ring gear 7 is rotated counterclockwise, and makes planet wheel 3 around O on the one hand
2Axle rotation counterclockwise, planet wheel 3 is revolved round the sun counterclockwise around the O axle, when planet wheel 3 rotates counterclockwise, by stirring of tooth, make override type gear 8 clockwise rotate again, override type gear 8 drives passive live axle 9 (bicycle rear axle) and turns clockwise, and just drives bicycle and travels forward.
When second wire rope 6 that rotates around ring gear 7 moves to certain distance and comes to a halt, passive live axle 9 (bicycle rear axle) still continues rotation according to inertia, but because 8 employings of override type gear is the override type gear, so passive live axle 9 can't drive override type gear 8 and rotate counterclockwise; When second wire rope 6 comes to a halt, second spring 15 begins to shrink makes ring gear 7 turn clockwise, driving override type gear 8 by planet wheel 3 is rotated counterclockwise, because override type gear 8 is override type gears, so override type gear 8 is rotated counterclockwise and can't drives passive live axle and be rotated counterclockwise, that is to say that passive live axle 9 still continues to turn clockwise, drive bicycle and move forward.When ring gear 7 after turning back to reset condition under the effect of second spring 15, second chock 13 turns back to original position and again ring gear 7 is limited under the effect of second torsion spring 17, ring gear 7 has just been finished a two-way process like this.Because kicking the formula bicycle is alternately to kick foot treadle, chock 12,13 can't be disengaged stop simultaneously, so tie-rod 4 and ring gear 7 can't be worked simultaneously, whole epicyclic gear train also just has only an input end and an output terminal.By top principle Analysis as can be known, the left and right pin of bicycle is alternately kicked forward, goes round and begins again, and bicycle is travelled forward.
