Abstract

The utility model relates to a power saving device for a bicycle, which is composed of a big gear, a pinion and two chain wheels, the big gear and the pinion are in coaxial connection and are arranged in a chain box of the bicycle; the big gear is engaged with one chain wheel; the other chain wheel is engaged with a gear of a back wheel of the bicycle; the pinion is coupled with a big chain wheel of the bicycle through a chain. The utility model alters the force moment of the bicycle; the utility model has labour saving when climbing or loading; the utility model has simple structure and low cost.

Description

Bicycle power-saving devices
The utility model belongs to a kind of bicycle power-saving devices.
At present, bicycle is all required great effort when upward slope or load-carrying 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 purpose of this utility model provides a kind of bicycle power-saving devices, by increasing large and small gear and two sprocket wheels, changes the moment of bicycle, reaches the labour-saving purpose.
The utility model is made up of large and small gear and two sprocket wheels, big gear wheel (3) and miniature gears (4) is coaxial is fixed on the chain cover wherein, on the axle bearing is housed, big gear wheel (3) and sprocket wheel (5) engagement, and sprocket wheel (6) again with the engagement of the gear (7) of bicycle rear, miniature gears (4) links by the hinge wheel (1) of chain (2) and bicycle, and its middle sprocket (6), (6) are coaxial fixing, and sprocket wheel (5), (6) diameter can be different so that reach the speed change purpose.
The utility model has only increased large and small gear and two sprocket wheels than ordinary bicycle, changes the moment of bicycle, no matter upward slope or load-carrying 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;
Fig. 2 is the front view of the utility model sprocket wheel;
Fig. 3 is the cutaway view of the utility model sprocket wheel.
Big gear wheel in the utility model (3), miniature gears (4) all can be bought with sprocket wheel (5), (6), on chain cover, bore two axis holes, pressing figure installs this device, the sprocket wheel (6) and the gear (7) of bicycle rear are meshed, with chain (2) miniature gears (4) is linked to each other with bicycle hinge wheel (1), shake bicycle pedals, adjust the back lash between each gear sprocket wheel, after adjusting, refill chain cover, pay special attention to the firm of respective aperture on large and small gear and the chain cover, shake the foot-operated of bicycle again and debug.
