Abstract
A kind of bicycle with level drive of forming by front-wheel, trailing wheel, handlebar, power rail, power wheel, flywheel and floral disc, power rail passes rear axle, and floral disc is located on the strut bar of vehicle frame, and power wheel is the concentric interlock gear of floral disc, between floral disc and flywheel, be with chain, be connected with chain and extension spring between power wheel and power rail, the bicycle structure of Gou Chenging is simple thus, and the labor-saving effect is remarkable, speed of a motor vehicle height, and the tire profile is trapezoidal, endurance, and range of use is wide.
Description
The present invention relates to a kind of bicycle, particularly a kind of bicycle that replaces stretcher with lever.
Standard bicycle is to make garden Zhou Yundong and drive rear wheel by chain by foot-operated, thereby order about cycle racing, this bicycle effort, a kind of in addition " pedal-type force saving bicycles " (number of patent application 921035373) places the imput shaft outer end with drive sprocket, two step on handle uses half garden ratchet sprocket piece to replace, and on the two-wheeled sheet chain is housed, and pedal is equipped with in the chain lower end, this bicycle is laborsaving than the former, but complex structure.
The object of the present invention is to provide a kind of simple in structure, the significant bicycle in labor-saving effect.
The present invention realizes like this, it comprises front-wheel, trailing wheel, handlebar, power wheel, flywheel and floral disc, flywheel fixedly is located on the rear axle, floral disc is located on the strut bar of vehicle frame, between flywheel and floral disc, be with chain, power wheel is the concentric interlock gear of floral disc, is with chain on power wheel, and the rear end of this chain connects extension spring, power rail passes rear axle, before by rear axle power rail being divided into, two sections of backs, preceding power rail is connected with chain on the power wheel, and back power rail is connected with extension spring on the power wheel, the top of spider is provided with extension spring, this extension spring is connected above-mentioned flywheel with the middle of power rail, floral disc, corresponding each cover can work independently about power rail.
The invention will be further described now to reach enforcement one example in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present invention.
As shown in Figure 1, the present invention includes front-wheel (1), trailing wheel (2), handlebar (3), power wheel (4), flywheel (5) and floral disc (6).The front and back wheel cover tire is trapezoidal.Two cooresponding flywheels (5) fixedly are located on the rear axle (7), rotate synchronously with rear axle (7).Two cooresponding floral discs (6) are located on the strut bar (9) of vehicle frame (8), are with chain (10) between flywheel (5) and floral disc (6).Two cooresponding power wheels (4) are the concentric interlock gear of floral disc (6), are with power chain (11) on power wheel (4), and the rear end of power chain (11) is connected with extension spring (12).Being fixed with three clamping plate (14) and clamping plate (14) on the back cant beam of spider (13) extends down by the back cant beam.Two cooresponding power rails (15) are for passing the cross bar of rear axle (7), by rear axle (7) power rail (15) is divided into preceding power rail (16) and back power rail (17), before power rail (16) be clipped in clamping plate (14) it, can be up and down in clamping plate (14), and the top of preceding power rail (16) is provided with foot-operated (18), and foot-operated (18) are positioned between front and back wheel (1), (2).Active chain (11) on the power wheel (4) is connected with preceding power rail (16), and the extension spring (12) on the power wheel (4) is connected with back power rail (17).The top of spider (13) is provided with an extension spring (19), and this extension spring (19) is connected with the middle part of power rail (15).
In the time of by bike, pedal is on foot-operated (18), up-and-down movement, by the extension spring (19) on the spider (13) and the effect of the extension spring (12) on the power wheel (4), power rail (15) moves up and down thereupon, by the chain (11) on power rail (15) the drive power wheel (4), moment is passed to power wheel (4), and power wheel (4) and floral disc (6) are concentric interlock gear, then power is passed to chain (10) between flywheel (5) and the floral disc (6) by floral disc (6), drive flywheel (5) and trailing wheel (2) by chain (10), drive wheels travels forward.
This bicycle is a fulcrum with the rear axle,, only need move up and down in the time of by bike as power arm with lever, and both feet make useful work entirely, thereby the labor-saving effect is remarkable, speed of a motor vehicle height; The vehicle tyre profile is trapezoidal, endurance, and range of use is wide; In addition, this bicycle structure is simple, and cost is low.
