Abstract
The utility model provides a speed-increasing device for a bicycle, which is composed of a bicycle frame, a chain wheel of the bicycle, a composite sprocket, a bicycle freewheel and a chain, wherein, the composite sprocket is fixed on the bicycle frame; the chain wheel of the bicycle is connected with a minor sprocket of the composite sprocket via the chain; a big chain wheel of the composite sprocket is connected with the bicycle freewheel via the chain. The speed-increasing device for the bicycle has the advantages of reasonable design, simple structure, easy machining, small size, convenient operation, one object with multiple functions, etc.
Description
The utility model relates to a kind of bicycle chain driving device, specifically a kind of bicycle speed increaser.
From appear on the market the so far history of existing centuries of bicycle, though the bicycle producer of countries in the world studies intensively constantly and weeds out the old and bring forth the new, vehicle has produced many improvement, the kind style is innumerable, but few of improvement with regard to its integral structure is fixed on the front vehicle fork as front-wheel, trailing wheel is fixed on the vehicle frame, sprocket wheel is fixed on central frame beam, the front-wheel controlling party to, trailing wheel provides driving dynamics etc. by chain wheel drive.In China, though to be people the most familiar and use the most general a kind of vehicle for bicycle, the title that bikedom is arranged, several times develop on the structure of bicycle and introduce, absorbed both at home and abroad the advantage of popular bicycle, almost arrived perfect stage, but concerning the people of those manufacturers and research to power in bicycle, panesthesia also has unsatisfactory place, it is more laborsaving to wish that also bicycle is ridden, the speed of wishing bicycle running concerning those bicycle races sportsman can be faster, thereby just produced variable speed bicycle, on the hind axle of bicycle and pedal, added the turriform sprocket wheel, by speed change speedup or the reinforcing recently that changes two turriform sprocket wheels.But with regard to cost, but improved many, how to make ordinary bicycle also have the function of variable speed bicycle, and still keep ordinary bicycle economical and practical, ride band goods all can performance, need not buy new car is to transform a little just can realize the speedup purpose on original bicycle, be consumers in general's hope, the present this bicycle that uses in the rural area, small towns that can adapt to does not also have product to appear on the market.
The purpose of this utility model provides a kind of ordinary bicycle that can make and also has the same performance of variable speed bicycle, rides more laborsaving, moving velocity bicycle speed increaser faster.
The purpose of this utility model realizes in the following manner, add the compound speed-changing chain of a detouchable at ordinary bicycle, multiple-chain gear wheel can be connected when underloading or road are smooth and make variable speed bicycle into and use, bad or it can be pulled down as ordinary bicycle when needing camel band goods and use at road.
Accompanying drawing 1 is the use structural representation of bicycle speed increaser.
Accompanying drawing 2 is the structural representation of bicycle speed increaser.
Explain below with reference to Figure of description speed-increasing device for bicycle of the present utility model being done.
Speed-increasing device for bicycle of the present utility model, its structure are by cycle frame 1, bicycle chain Wheel 2, multiple-chain gear wheel, bicycle freewheel 3 and chain 4 consist of, and multiple-chain gear wheel is fixed on bicycle On the vehicle frame 1, bicycle chainwheel 2 joins compound chain by the minor sprocket 5 of chain 4 and multiple-chain gear wheel The hinge wheel 6 of wheel is joined by chain 4 and bicycle freewheel 3.
Multiple-chain gear wheel is to be made of bracing frame 7, sprocket shaft 8, hinge wheel 6 and minor sprocket 5, and hinge wheel 6 and minor sprocket 5 are composite and fixed at the end of sprocket shaft 8, and sprocket shaft 8 is fixed in the bracing frame 7, and bracing frame 7 is by on the vertical beam that is bolted to cycle frame 1.
Embodiment:
Its processing and fabricating of bicycle speed increaser of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.The making of size multiple-chain gear wheel and bracing frame process for machining is routinely carried out, and during making big or small multiple-chain gear wheel is composite and fixed at together, by sprocket shaft multiple-chain gear wheel is fixed in the bracing frame again.During use bracing frame is fixed by bolts on the vertical beam of cycle frame, link together with the minor sprocket of chain bicycle chainwheel and multiple-chain gear wheel, link together with the hinge wheel and the flywheel of original chain, bracing frame is slided up and down the elasticity of adjusting chain just can use multiple-chain gear wheel.The time spent can not received original chain the function of replying ordinary bicycle on the bicycle chainwheel by opposite step.
Speed-increasing device for bicycle of the present utility model is compared with existing technology, and has reasonable in design, structure Simply, be easy to the characteristics such as processing, little, easy to use, the one-object-many-purposes of volume, thereby, have very Good extension use value.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
