Abstract
The utility model relates to a forward installed axle and chainless bicycle which relates to an improvement of bicycles. The front end of a transmitting axle (5) is provided with a bevel gear (5-1), and the back end of the transmitting axle is provided with a bevel gear (5-2). The middle part of a pedal resetting device (10) is fixed on the front end of a transverse beam (9) and the back part of a front wheel (2) by a fixing device (11). Front ends of two pedals (6) are respectively fixed on both ends of the pedal resetting device (10). A driving bevel gear (8) is fixed on the inner side of a single direction bearing (4) and is coaxial with the single direction bearing, and the bevel gear of the back end of the transmitting axle is engaged with a driven bevel gear (7) which is fixed on the back end of the transverse beam. The utility model develops the new forward installed axle and chainless bicycle which has the advantages of compact structure, riding labor saving, convenience, comfortable feeling and folding portability.
Description
Technical field: the utility model 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.
The utility model content: the utility model has been developed a kind of novel axis reach chain-less bicycle, the utility model compact conformation, ride laborsaving, convenient, comfortable, novel, be convenient to fold and carry.The utility model has comprised bicycle handle 1, front-wheel 2, trailing wheel 3, crossbeam 9, and front-wheel 2 is fixed on the below of bicycle handle 1, and front-wheel 2 is connected by crossbeam 9 with trailing wheel 3.It has also comprised the anchor fitting 11 of unilateral bearing 4, transmission shaft 5, pedal 6, driven wheel of differential 7, drive bevel gear 8, pedal reset attachment 10, pedal reset attachment 10, the front end of transmission shaft 5 is provided with finishing bevel gear cuter 5-1, the rear end of transmission shaft 5 is provided with finishing bevel gear cuter 5-2, the middle part of pedal reset attachment 10 is fixed on the front end of crossbeam 9, the rear of front-wheel 2 by anchor fitting 11, and the front end of two pedals 6 is separately fixed at the two ends of pedal reset attachment 10; The center fixation of unilateral bearing 4 is on crossbeam 9 and be arranged on the rear of pedal reset attachment 10, drive bevel gear 8 is fixed on the inboard and coaxial with unilateral bearing 4 of unilateral bearing 4, the middle part of two pedals 6 is anterior partially captives joint with unilateral bearing 4 unidirectional running parts, the front end finishing bevel gear cuter 5-1 of transmission shaft 5 is meshed with drive bevel gear 8, the rear end finishing bevel gear cuter 5-2 of transmission shaft 5 is meshed with driven wheel of differential 7, and driven wheel of differential 7 is with the rear end that fixes on crossbeam 9.The utility model has designed a kind of laborsaving simplified structure chain-less bicycle, and transmission principle is similar to common chain-less bicycle, and the key distinction is that its vehicle frame is " one " font body frame, and axis moves on to front-wheel 2 rear portions.Its driver train contains pair of parallel pedal 6, pedal 6 can only be in certain angle up-and-down movement, pedal 6 is a pair of unilateral bearing 4 with the axis joint, can both make the drive bevel gear unidirectional rotation on the axis when guaranteeing that both feet depress, thereby the driven wheel of differential 7 that drives on crossbeam 9 rear ends by transmission shaft 5 rotates, and rotates thereby drive trailing wheel 3.The utility model user can change the arm of force to adapt to different road conditions by mobile step point.Because bicycle structure has been simplified in axis reach greatly, and the gear transmission waste of power greatly reduces, and is very beneficial for the minimizing of bicycle volume and weight, and the raising of driving efficiency and function expansion; The utility model compact conformation, ride laborsaving, convenient, comfortable, novel, be convenient to folding carrying.
Description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 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 9, unilateral bearing 4, transmission shaft 5, pedal 6, driven wheel of differential 7, drive bevel gear 8, pedal reset attachment 10, the anchor fitting 11 of pedal reset attachment 10 is formed, front-wheel 2 is fixed on the below of bicycle handle 1, front-wheel 2 is connected by crossbeam 9 with trailing wheel 3, the front end of transmission shaft 5 is provided with finishing bevel gear cuter 5-1, the rear end of transmission shaft 5 is provided with finishing bevel gear cuter 5-2, the middle part of pedal reset attachment 10 is fixed on the front end of crossbeam 9 by anchor fitting 11, the rear of front-wheel 2, the front end of two pedals 6 are respectively with the two ends that fix on pedal reset attachment 10; The center fixation of unilateral bearing 4 is on crossbeam 9 and be arranged on the rear of pedal reset attachment 10, drive bevel gear 8 is fixed on the inboard and coaxial with unilateral bearing 4 of unilateral bearing 4, the middle part of two pedals 6 is anterior partially captives joint with unilateral bearing 4 unidirectional running parts, the front end finishing bevel gear cuter 5-1 of transmission shaft 5 is meshed with drive bevel gear 8, the rear end finishing bevel gear cuter 5-2 of transmission shaft 5 is meshed with driven wheel of differential 7, and driven wheel of differential 7 is fixed on the rear end of crossbeam 9.
Described driven wheel of differential 7 is the unidirectional finishing bevel gear cuter that slides.Driven wheel of differential 7 selects for use unidirectional finishing bevel gear cuter can reduce waste of power in sliding; When pedal 6 is not scrunched, can slide forward freely.
Described pedal reset attachment 10 is a plate spring sheet; This plate spring sheet can make pedal 6 automatically reset.
As shown in Figure 2, 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.
