One unilateral small axle is installed, the unilateral small axle on the right of the left side is each passed through the hollow shaft on the left side and the right, on the right of the left side
Unilateral small axle and hollow shaft between ultra-thin long bearing is installed, the other end of the unilateral small axle on the right of the left side is fixed with company
Extension bar, the other end of the connecting rod are fixedly connected with vehicle frame.
A kind of vertical treading gearratio of utility model in this with the bicycle drive trampled change in location and changed,
The transmission belt is chain, belt, rope, steel disc.
A kind of vertical treading gearratio in the utility model with the bicycle drive trampled change in location and changed,
The curve of the curve wheel is that the curve of the curve wheel is because of car type according to the different drive ratios demand setting for each trampling position
Difference can have different settings.
Compared with prior art, the present invention has the effect that：Above-mentioned vertical treading gearratio is with trampling change in location
And the bicycle drive changed, firmly dead angle and the gearratio that its customer service circumference is trampled can not periodically variable lack
Fall into；The present invention is trampled by straight line, is set rational periodically variable gearratio, is constructed the transmission for being more suitable for human motion
Device, being more suitable for the motion mode of human body, to make one in motion process heat caused by itself less, so as to make one same
More existing bicycle has given play to bigger power during the tired degree of sample.

Embodiment
Below in conjunction with the accompanying drawings and example is described in detail by the utility model.
As Figure 1-4, a kind of straight line tramples gearratio with the bicycle drive trampled change in location and changed, its
Including left and right it is each it is a set of it is the same trample transmission facility, by the convolution part relation of centre together；It is described to trample transmission and set
The slide rail 8 including being fixed on vehicle frame is applied, the upper end of slide rail 8 is provided with pulley 7, and sliding block 22 is housed on the slide rail 8, described
Sliding block lower end is fixed with pedal 9, and the sliding block 22 is fixedly connected with the one end of transmission belt 6, and slide rail 8 is wound among the transmission belt 6
On the pulley 7 of upper end, the other end of transmission belt 6 is fixedly connected with the transmission belt connecting hole 21 on curve wheel 4, the curve wheel
According to being the change demand that meets gearratio, the position of curve wheel fixing hole 20 of the curve wheel 4 is fixedly mounted 4 curve setting
A ratchet-gear wheel 13 is fixedly mounted in one hollow shaft 2, the centre position of hollow shaft 2, and the outer ring of ratchet-gear wheel 13 is fixed with flower-drum 3 to be connected
Connect, the other end of hollow shaft 2 is fixedly mounted one big ring gear 14, each a set of the same the trampling in left and right be driven facility its
The big ring gear 14 of left and right, respectively with circle round part two one end of little gear 15 engage.
A kind of straight line in the utility model tramples gearratio with the bicycle drive trampled change in location and changed：
The convolution part includes the little gear 15 of two intermeshing half, and the little gear 15 is described built with ultra-thin bearing 16
Small axle 10 is installed, the both ends of the small axle 10 are fixed on two disks 17, described two disks 17 in ultra-thin bearing 16
Centre position is fixedly mounted a unilateral small axle 11 respectively, and the unilateral small axle 11 on the right of the left side is each passed through the left side and the right
Hollow shaft 2, ultra-thin long bearing 16 is installed between the unilateral small axle 11 and hollow shaft 2 on the right of the small left side, the left side is right
The unilateral small other end of axle 11 on side is fixed with connecting rod 1, and the other end of the connecting rod 1 is fixedly connected with vehicle frame.
Operation principle of the present utility model is：Pin pushes pedals 9, band movable slider 22 move downward, and sliding block 22 drives transmission
Band 6 moves, and transmission belt 6 drives curve wheel 4 to rotate around pulley 7, and curve wheel 4 drives hollow shaft 2 to rotate, and hollow shaft 2 drives spine
Gear 13 rotates, and ratchet-gear wheel 13 drives flower-drum to rotate, while hollow shaft 2 also drives big ring gear 14 to rotate, the big band of ring gear 14
A dynamic little gear 15 rotates, and little gear 15 drives another opposite direction of little gear 15 to rotate, and another little gear band 15 drives another big
Gear ring 14 rotates, and another bull gear 14 drives another hollow shaft 2 to rotate, and another hollow shaft 2 drives another curve wheel 4 to rotate, separately
One curve wheel 4 drives another transmission belt 6 another transmission belt 6 is wound in another curve wheel transmission trough of belt 19 when rotating, Ling Yichuan
Dynamic band 6 drives another sliding block 22 to move upwards around another pulley 7：It is another when the sliding block 22 on one side moves to bottom
The sliding block 22 on side is just moved to topmost, and pin is trampled in change, so circulation.
Gearratio change of the present utility model is driven grooved bottom curve 18 by curve wheel and determined, in the mistake trampled
The change of transmission belt 6 and radius at the point of contact of curve wheel transmission grooved bottom curve 18 correspond to the change of gearratio in journey.
Certainly, those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to explanation originally
As long as utility model and be not used as to the utility model in spirit of the present utility model, to implementation described above
Change, the modification of example will all fall in the range of claims of the present utility model.
