Be that adjoint of the present invention is described in further detail below: referring to Fig. 1, vehicle frame is made up of rear vehicle fork 2, fender 3, vertical rod 4, girder 6, front vehicle fork 10, bull stick 8 and handlebar 9, and thing bucket 7 is positioned on the girder 6 fixing, and trailing wheel 13 is a drive wheel.Referring to Fig. 2, trailing wheel main shaft 25-1 two ends connect rocking bar 1, the hinged treadle 16 of rocking bar 1 other end, assembling sole 15 above treadle 16 front ends, the hinged pull bar 14 in treadle 16 middle parts, pull bar 14 upper ends are hinged on girder 6 and vertical rod 4 connecting places, also can directly be hinged on vertical rod 4 or the girder 6.Referring to Fig. 3, this is driving principle figure, trailing wheel main shaft 25-1 goes up mounting bush 17-1 and gear case 19, the assembling capping 18 of gear case 19 right sides, capping 18 internal diameters and sleeve pipe 17-1 bolt 28 sealing and fixing, in gear case 19, trailing wheel main shaft 25-1 goes up the fixing powershift gear 23 that initiatively adds, main shaft 25-1 goes up with bearing assembling satellite wheel rocking bar (or shaking tray) 22 and this sleeve pipe of sleeve pipe 17-1 17-1 and goes up fixing vehicle wheel driven wheel 24, several little axles 21 of assembling on satellite wheel rocking bar or the shaking tray 22, satellite gear 20 is all assembled at little axle 21 two ends, and the satellite gear 20 at two ends initiatively adds powershift gear 23 with ingear separately respectively and wheel drive gear 24 cooperates.Rear vehicle fork 2 is assembled with bearing in main shaft 25-1 both sides, and axle 25-1 end is rocking bar or rocking arm 1 fixedly.As cyclist by bike the time, rocking bar 1 rotates and drives trailing wheel main shaft 25-1 rotation, initiatively add powershift gear 23 rotates thereupon, ingear satellite gear 20 is rotated, comprise revolution and rotation, by little axle 21 and satellite wheel rocking bar 22 and transmission, ingear satellite gear 20 rotates on the wheel drive gear 24, gear 24 rotates together by sleeve pipe 17-1 drive capping 18 and gear case 19 like this, and main shaft 25-1 both sides capping 18 connects trailing wheels 13, and bicycle advances thus.When the cyclist stopped to trample, the bicycle utilization was used to power and is still moved on.At this moment, main shaft 25-1 initiatively adds powershift gear 23 and all stops operating, and trailing wheel 13 drives sleeve pipe 17-1 by capping 18 or gear case 19 and rotates, and wheel drive gear 24 drives satellite gear 20 again and rotates, and left satellite gear 20 revolves round the sun around initiatively adding powershift gear 23.In the time need braking by bike, reversing sense is trampled and is made main shaft 25-1 counter-rotating, and speed reversal and strength are light, and then brake weight is little, and then brake weight is big on the contrary.Referring to Fig. 4, this is the 2nd a kind of structure of foot-operated transmission, promptly gets final product at the present commercially available bicycle pedals of rocking bar 1 end assembling; Can find out also that from figure gear case 19 outer circumferential edge connect common trailing wheel commonly used 13 by spoke 27.Referring to Fig. 5, can find out that gear case 19 biside plate round edges connect spoke 27, this is a kind of trailing wheel version.Referring to Fig. 6, this is another kind of trailing wheel version, gear case 19 is positioned at the right side, capping 18 is gear case 19 sides, also be the spherical osed top cappings 18 in wheel both sides, these capping 18 internal diameters link to each other with sleeve pipe 17-1, the external diameter edge is by sealing gland bar 31 sealing assembling outer rubber tire 29-1, outer rubber tire tire 29-1, outer rubber tire 29-1 radially-outer surface directly touches ground, and mouse cage is formed in several sealing gland bars 31 and two mouse cage dish 32 cross-under, is assemblied in and plays support and leak free effect in the leak free wheel, can fill high pressure gas in the wheel and form air cavity 30, cage-shaped structure is seen shown in Figure 7.Referring to Fig. 8, this is the bicycle fore wheel structure, and front-wheel main shaft 25-2 assembles spherical top cover 34 with bearing in both sides, perhaps connects top cover 34 with bearing mounting bush 17-2 sleeve pipe 17-2, top cover 34 outer edges connect glue tire 33 in the whole tire inner surface assembling of outer rubber tire 29-2, and the connection aerating chews 35.

Advantage of the present invention and effect are as follows:

1, owing to adopting the transmission of trailing wheel epicyclic train to compare with traditional chain drive, so transmission efficiency is higher, also The problem of having avoided chain easily to come loose.

2, owing to adopt built-in transmission mechanism, so have the good greasy property that has, reduced mechanical wear, passed Efficiency of movement and maintenance property are better, have avoided the problem of chain drive inconvenience.

3, owing to adopt the inflatable ball wheel, so have good elasticity, its deflection is relevant with the elastomer cumulative volume, both Laborsaving again damping.

4, because body frame structure for automotive changes, and the vehicle seat center of gravity is backward mobile, and the requirements such as intensity of front-wheel and vehicle frame can reduce, So simple in structure, weight saving, convenient in carrying is applicable to the floor user.

5, on probation through manufacturing experimently, respond well, the transmission efficiency height; Use laborsaving, convenient; Whole service life is long; Simple in structure, cost is low; The braking safe performance is reliable; Wheel elasticity and damping performance all increase.
