Detailed description of the invention

In conjunction with Fig. 1 to Fig. 3, the present invention includes front-wheel 10 and front fork 11, and be connected in vertical horizontal 20 handle, vertical swing part 21 and the fixed part 22 of comprising, fixed part 22 bottoms are fixedly connected with front fork 11, between swing part 21 and fixed part 22, be rotationally connected by rotatable parts, swing part 21 is made back and forth movement along front-wheel 10 directions of advance.

Rotatable parts between swing part 21 and fixed part 22, it comprises the forearm 51 and the postbrachium 52 that connect by rotating shaft 50, the direction of axis line of this rotating shaft 50 is vertical with front-wheel 10 directions of advance. Forearm 51 is fixedly connected with swing part 21, and postbrachium 52 is fixedly connected with fixed part 22.

Fixed part 22 is provided with the support 30 stretching out forward, and support 30 is provided with driving shaft 31, and in the present embodiment, the direction of axis line of this driving shaft 31 is vertical with front-wheel 10 directions of advance.

The two ends of driving shaft 31 are respectively equipped with driving wheel 32 and drive 33, and driving wheel 32 is in transmission connection with flywheel 13, a flywheel 13 and driving wheel 32 identical side on front axle 12.

On drive 33, be wound with chain 40, described chain 40 one end are fixedly connected on front axle 12 by spring 41, and the other end is fixed on vertical swing part 21. By pulling of chain 40, drive 33 is rotated, just can rotate by flywheel driven 13 with the driving wheel 32 of drive 33 coaxial rotation, wheel is advanced. The effect one of spring 41 is in order to make chain 40 return to original position, to be convenient to work next time; Two be to provide horizontal 20 and swing part 21 recover the power of origin-location, carry out and so forth.

Because the amplitude of fluctuation of swing part 21 is limited, so the needed length of chain 40 is also limited. In addition, if chain 40 is directly connected with swing part 21, that chain 40 is in swinging along with swing part 21, and its angle, direction are not being stopped variation, are therefore easy to occur falling the situation of chain.

In order to solve this two problems, in the present embodiment, be provided with rigidity rope 42 at chain 40 and between vertical fixed part 22, rigidity rope 42 one end connect chain 40, and the other end is fixed on fixed part 22. On swing part 21, be also provided with carrying roller 23, rigidity rope 42 is around carrying roller 23 1 circles, and its two ends connect respectively chain 40, fixed part 22. By when rigidity rope 42 is by after carrying roller 23, the tangential direction between chain 40 and drive 33 is immobilized.

Be can not fall chain when stablizing chain 40 and to work equally, be provided with support roller 70 in the front of drive 33, the supporting-roller shaft 71 of support roller 70 and the axis parallel of driving shaft 31, supporting-roller shaft 71 is fixed on support 30 by vertical trailing arm. In the present embodiment, chain 40 is that the return pulley face of walking around drive 33 is walked around after the upper wheel face of support roller 70 again, and two ends are connected in front axle 12, rotating part 21 by spring 41 and rigidity rope 42 respectively again.

As shown in Figure 4, vertically trailing arm comprises the straight tube 72 being fixed on support 30, and the inserted link 73 that is connected with supporting-roller shaft 71 bearings of one end, and straight tube 72 is provided with the bolt 74 radially inwardly screwing, and inserted link 73 holds out against fixing by bolt 74.

Height can be fixing by inserted link 73 when the height of support roller 70 time changes, and therefore its effect is to compress chain 40, falls chain while preventing its work.

Bottom at swing part 21 is provided with positioning element, can change the type of drive of bicycle by positioning element. As shown in Figure 5, positioning element is the spring holder 60 of being located in swing part 21, and spring holder 60 is connected in the pin-and-hole (not shown) on support 30. By spring holder 60, by after fixing swing part 21, swing part 21 cannot swing, and now, bicycle can only drive with original foot pedal type driving mechanism. Open spring holder 60, just can carry out front-wheel drive by driving mechanism of the present invention and advance.

After swing part 21 is fixing by spring holder 60, the type of drive of bicycle is traditional rear-guard mode, now front-wheel 10 advance still can, if need to move backward backward, due to the tooth effect of stinging in flywheel 13, will inevitably make driving wheel 32 also rotate. And driving wheel 32 and drive 33 are coaxial rotation, the fixing of swing 21 caused again the fixing of chain 40, so front-wheel 10 can cannot rotate backward.

In order addressing this problem, in the present embodiment, on driving wheel 32, to be also provided with and to make driving wheel 32 depart from the clutch 80 of transmission.
