Abstract

The utility model relates to a labour-saving device for bicycle, which comprises big, middle and pinion gears. The big gear is coaxial with the minor sprocket of the bicycle; the pinion gear is arranged on the rear wheel spindle of the bicycle; through an idler, the torque of the bicycle is altered. Without reference to uphill or heavy-load, the utility model has the advantages of labour saving, simple structure and low cost.

Description

Labour-saving device for bicycle
The utility model belongs to a kind of bicycle power-saving devices.
At present, bicycle is all required great effort when upward slope or heavy duty very much, some people reaches the labour-saving purpose from the speed of a motor vehicle that changes bicycle, but the structure great majority are more complicated all, patent 91209538.5 3 fast bicycle shift axis for example, patent 91218470.1 three-wheel vehicle work-saving device etc., effect is also not really desirable.
The utility model increases large, medium and small three gears, changes the moment of bicycle, just can reach the labour-saving purpose.
The utility model is made up of large, medium and small gear, coaxial being fixed on the chain cover of minor sprocket (3) of big gear wheel (4) and bicycle, on the axle bearing is housed, again by intermediary wheel (5) and miniature gears (6) engagement, intermediary wheel (5) is fixed on the chain cover with axle, miniature gears (6) is coaxial with the trailing wheel of bicycle, and minor sprocket (3) links by chain (2) and hinge wheel (1).
The utility model has only increased large, medium and small three gears than ordinary bicycle, changes the moment of bicycle, no matter upward slope or heavy duty are all very laborsaving, simple in structure, cost is low, is suitable for and promotes the use of.
Description of drawings:
Fig. 1 is the utility model constructional drawing
The utility model middle gear (4), (5), (6) all can buy, on chain cover, bore two axis holes, by figure the minor sprocket (3) of gear (4) with bicycle is contained on the same axle, intermediary wheel (5) and big gear wheel (4) engagement, miniature gears (6) is contained on the bicycle rear shaft, note adjusting gear (4), (5), (6) back lash between, minor sprocket (3) links to each other with bicycle hinge wheel (1) with chain (2), shake bicycle pedals, adjust each gear, closing between the sprocket wheel nibbled the gap, after adjusting, refill chain cover, pay special attention to big gear wheel (4),, respective aperture is fastening on intermediary wheel (5) axle and the chain cover, shakes the foot-operated of bicycle again and debugs.
