Description
Technical field: the present invention relates to a kind of improvement of bicycle.
Background technology: existing have the chain bicycle structure very complicated, and manufacturing cost is very high, and the efficient of transmission is very low; On the market a lot of chain-less bicycles are arranged also now, but these existing chain-less bicycles have all kept middle shaft drive, both feet must move in a circle when riding, and mechanical efficiency is very low, and because the existence of axis, make the bicycle structure complexity, volume, weight are big, are unfavorable for folding, and compare with traditional chain-driving bicycle, advantage is not remarkable, so chain-less bicycle never becomes the main flow in market.
Summary of the invention: the present invention moves chain-less bicycle after having developed a kind of novel axis, and the present invention adopts gear transmission, compact conformation, it is laborsaving, convenient, comfortable, novel to ride, be convenient to folding carrying.The present invention has comprised bicycle handle 1, front-wheel 2, trailing wheel 3, crossbeam 4, and front-wheel 2 is fixed on the below of bicycle handle 1, and front-wheel 2 is connected by crossbeam 4 with trailing wheel 3; It has also comprised pedal 5, pedal reset attachment 6, pedal reset attachment bearing 7, change-gear set 8, pedal reset attachment bearing 7 is fixed on the rear end of crossbeam 4, the place ahead of trailing wheel 3, the top of the middle part of pedal reset attachment 6 and pedal reset attachment bearing 7 is movably hinged, the two ends of the middle part of two pedals 5 and pedal reset attachment 6 are movably hinged, the rear end of pedal 5 is connected with change-gear set 8, and change-gear set 8 is fixed on the wheel shaft 3-1 of trailing wheel 3.The present invention is owing to move on to hind axle with axis, simplified bicycle structure greatly, and the waste of power of straight-tooth gear transmission greatly reduces than chain and bevel drive, be very beneficial for the minimizing of bicycle volume and weight, and the raising of driving efficiency and function expansion, especially be fit to make miniature walking-replacing tool, also can be Kickboard Scooter and install driving additional.
Description of drawings: Fig. 1 is a structural representation of the present invention, and Fig. 2 is the structural representation of change-gear set 8 in the specific embodiment one, and Fig. 3 is the structural representation of baggage car in the specific embodiment.
The specific embodiment one: as shown in Figure 1, this specific embodiment is by bicycle handle 1, front-wheel 2, trailing wheel 3, crossbeam 4, pedal 5, pedal reset attachment 6, pedal reset attachment bearing 7, change-gear set 8 is formed, front-wheel 2 is fixed on the below of bicycle handle 1, front-wheel 2 is connected by crossbeam 4 with trailing wheel 3, pedal reset attachment bearing 7 is fixed on the rear end of crossbeam 4, the place ahead of trailing wheel 3, the top of the middle part of pedal reset attachment 6 and pedal reset attachment bearing 7 is movably hinged, the two ends of the middle part of two pedals 5 and pedal reset attachment 6 are movably hinged, the rear end of pedal 5 is connected with change-gear set 8, and change-gear set 8 is fixed on the wheel shaft 3-1 of trailing wheel 3.
As shown in Figure 2, described change-gear set 8 is by driving gear 8-1, quicken miniature gears 8-2, quicken big gear wheel 8-3, driven gear 8-4, accelerating gear axle 8-5, unilateral bearing 8-6 forms, unilateral bearing 8-6 is fixed on the hind axle 3-1, and be movably hinged with hind axle 3-1, unilateral bearing 8-6 is captiveed joint with the rear end of pedal 5, quickening miniature gears 8-2 is meshed with driving gear 8-1, quicken miniature gears 8-2 and quicken big gear wheel 8-3 by coaxial connection of accelerating gear axle 8-5, middle part and the crossbeam 4 of accelerating gear axle 8-5 are movably hinged, driven gear 8-4 is meshed with quickening big gear wheel 8-3, and driven gear 8-4 is coaxial with hind axle 3-1 and captive joint with the hind axle skin.
Described driven gear 8-4 is a ratchet, the degradation of energy when sliding with minimizing.
Described pedal reset attachment 6 is a plate-shaped springs; This plate-shaped springs has the suitable coefficient of stiffiness.
As shown in Figure 3, this driving device in this specific embodiment can also be applied in a lot of occasions of shopping cart, airdrome luggage car or the like.
This specific embodiment transmission principle is different fully with common chain-less bicycle, and all there is the driver train of independent symmetry the trailing wheel both sides.Vehicle frame is " one " font body frame, as accompanying drawing 1.Driver train contains pair of parallel pedal 5, splits the bicycle both sides, pedal 5 can only be in certain angle up-and-down movement.Axis moves on to the trailing wheel outside, and is coaxial with trailing wheel 3, replaces large ratchet with big gear wheel on the axis, and Pedalling is fixed on the unilateral bearing at big gear wheel center, only does one-way movement to guarantee big gear wheel.Be fixed with a pair of accelerating pulley on the back vent of both sides respectively.The driving process: as Fig. 2, drive driving gear 8-1 when pedal 5 moves downward, driving gear 8-1 drives and quickens miniature gears 8-2, quickens miniature gears 8-2 and drives the acceleration big gear wheel that is fixed on the trailing wheel 3, drives driven gear 8-4 then, advances thereby drive bicycle; When pedal 5 upwards resetted, each gear did not all move, and was driven by the same mechanism of opposite side.On the main car frame in this external trailing wheel the place ahead reseting leaf is arranged, reed has the suitable coefficient of stiffiness, when normally riding, utilize the stalk rod principle that left and right sides pedal is resetted mutually, can utilize bicyclist's own wt to make reed distortion when standing rest again, slide to guarantee that both feet can driven can parallelly be stood again.The user can change the arm of force to adapt to different road conditions by mobile step point.Because axis moves on to trailing wheel, simplified bicycle structure greatly, and the waste of power of straight gear transmission greatly reduces than chain and bevel drive, be very beneficial for the minimizing of bicycle volume and weight, and the raising of driving efficiency and function expansion, especially be fit to make miniature walking-replacing tool, also can be Kickboard Scooter and install driving additional.Compact conformation of the present invention, novel, drive comfortablely, be convenient to folding carrying, be fit to very much working, go to school.
