Abstract
The utility model provides a labor-saving gear drive bicycle, which comprises a bicycle body, wherein the left and right pedals of the bicycle are fixed on a frame between the front and back wheels of the bicycle body through a middle axle, and the middle axle and the wheel axle of the front and back wheels are the same horizontal panel; and the utility model is characterized in that a crank gear is arranged between the left and right pedals of the bicycle, and is fixed on the middle axle, the axle center of the back wheel is also provided with a flying gear, a gear train formed by gears which are connected with each other is arranged between the flying gear and the crank gear, the gear is fixed on a fixing plate through a gear shaft to form the gear train, the fixing plate is fixed on the frame between the crank gear and the flying gear, and the two ends of the gear train are respectively connected with the crank gear and the flying gear. The utility model has the advantages that compared with the existing chain-type bicycle, the gear drive bicycle is more labor-saving, the whole structure is lighter, and in addition, the bicycle is free from the trouble of chain falling and chain breaking.
Description
Technical field
The utility model relates to a kind of bicycle, particularly a kind of labour-saving gear driving bicycle.
Background technology
What bicycle on the market adopted at present is chain-type, because the problem of stress point, the bicycle of this type is ridden comparatively effort.
Summary of the invention
The purpose of this utility model is to provide a kind of gear driving bicycle of labour-saving.
Structure of the present utility model is such: it comprises bicycle body, foot-operatedly about bicycle be fixed on the vehicle frame between bicycle body's front and back wheel by axis, and axis and front and back wheel wheel shaft is on same horizontal surface; It is characterized in that: be provided with crank gear between riding about bicycle, crank gear is fixed on the axis, locate also to be provided with to fly gear in the axle center of rear wheel, flying to be provided with the gear cluster that interconnective gear constitutes between gear and the crank gear, gear cluster fixedly flies on gear and the direct cycle frame of crank, and the two ends of gear cluster are connecting crank gear and fly gear respectively.
Advantage of the present utility model is: 1 existing relatively chain-type bicycle, and the utility model is more laborsaving, and unitary construction is also more light; There is not the worry of chain sling, chain rupture in 2 bicycles of the present utility model.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Label declaration
1 bicycle body, about 2 foot-operated, 3 axis, 4 wheels, 5 vehicle frames, 6 crank gears, 7 fly gear, 8 gears, 9 gear clusters, 10 adapter plates.
The specific embodiment
As shown in Figure 1, it comprises bicycle body 1, and foot-operated 2 are fixed on the vehicle frame 5 between bicycle body's front and back wheel 4 by axis 3 about bicycle, and axis and front and back wheel wheel shaft are on same horizontal surface; Be provided with crank gear 6 between riding about bicycle, crank gear is fixed on the axis, locate also to be provided with to fly gear 7 in the axle center of rear wheel, flying to be provided with the gear cluster 9 that interconnective gear 8 is constituted between gear and the crank gear, gear cluster fixedly flies on gear and the direct cycle frame of crank, and the two ends of gear cluster are connecting crank gear and fly gear respectively.Fly to be provided with the gear cluster that interconnective gear constitutes between gear and the crank by being arranged on, can make the user step foot-operated in, drive bicycle and advance.
