Abstract
The utility model belongs to an accessory for a pedal bicycle, particularly a gearing device for a bicycle, which mainly comprises a main driving chain wheel, a back chain wheel, a small chain wheel, a chain wheel, a small chain wheel fixed on a flywheel of the chain wheel, a tension chain wheel, a chain and a fixing plate, wherein the small chain wheel arranged on a flywheel of the back chain wheel, the chain is wound on the driving wheel and the fixing plate is used for fixing the driving wheel. The utility model solves the defect that the existing device can not drive the back wheel when driven backwards. The utility model has the advantages that the structure is simple, the change for the existing bicycle is small, the bicycle can advance no matter whether the main driving chain wheel is driven forwards or backwards, etc.
Description
The utility model belongs to foot-operated vehicle accessory, is meant a kind of bicycle drive especially.
The driving device of present commercially available bicycle mainly relies on the sprocket wheel that is assemblied in axis and rear axle to drive chain and drives, when forward treadles, sprocket wheel drives trailing wheel and advances under chain drives, and when oppositely pedaling, then sprocket wheel does not play a driving role to wheel, pedals for a long time easily to make the bicyclist feel withered hot-tempered fatigue.
The purpose of this utility model is to provide a kind of forward and reverse Shi Junke of treadling carries out driving action to bicycle quick bicycle drive to overcome the deficiency of prior art.
Integral structure of the present utility model is:
Bicycle drive comprises the active main drive sprocket (1) that is assemblied in axis, actively is assemblied in the back sprocket wheel (4) of rear axle and is connected in chain (2) between the two; On the flywheel of back sprocket wheel (4), fixedly be equipped with minor sprocket (6), adapter plate (3) is assemblied on rear axle and the vehicle frame, sprocket wheel (9) is assemblied on the adapter plate (3) with flywheel is coaxial, the coaxial minor sprocket (10) that is equipped with on the flywheel of sprocket wheel (9), back sprocket wheel (4), sprocket wheel (9) and main drive sprocket (1) constitute one pair of transmission by chain (2) and pay, minor sprocket (6), (10) constitute one pair of transmission by chain (7) pays, and sprocket wheel (9) is opposite to the driving direction of flywheel with back sprocket wheel (4) to the driving direction of flywheel.
Other architectural features of the present utility model also have:
Also be equipped with idler sprocket (8) on the adapter plate (3), main drive sprocket (1), back sprocket wheel (4), sprocket wheel (9), idler sprocket (8) constitute one pair of transmission and pay.
Accompanying drawing of the present utility model has:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
The integral structure of present embodiment as shown in Figure 1, wherein adapter plate (3) and rear axle and car after-frame bolted, offer three bar holes (5) on the adapter plate (3), back sprocket wheel (4), the wheel shaft of sprocket wheel (9) and idler sprocket (8) respectively with each bar hole (5) bolted, wherein back sprocket wheel (4) and the flywheel that is assemblied on the back sprocket wheel (4) are consistent with ordinary bicycle, sprocket wheel (9) is opposite to the driving direction of flywheel with back sprocket wheel (4) to the driving direction that is assemblied in the flywheel on it, and all the other structures as described above.
The utility model is work like this: at first by shown in Figure 1 the parts assembly is finished, adjust back sprocket wheel (4) axle then, position in the bar hole (5) that sprocket wheel (9) axle and tension wheel (8) axle are offered on adapter plate (3) is with tension chain (2), (7), during sprocket wheel after the forward drive (4), flywheel on the back sprocket wheel (4) rotates thereupon, drive the minor sprocket (6) that is assemblied on back sprocket wheel (4) and the sprocket wheel (9) by chain (7), (10) rotate, during sprocket wheel after the reverse drive (4), chain (2) drives sprocket wheel (9) and minor sprocket (10) clickwise, the minor sprocket (6) that is driven on the back sprocket wheel (4) by chain (7) rotates, and advances thereby drive trailing wheel.
The obtained technological progress of the utility model is that it is simple in structure, to existing bicycle It is little that drive mechanism is changed, and main drive sprocket no matter forward and backward all can drive trailing wheel advances, Being particularly suited for the lower bicyclist of stature drives.
Claims (2)
1, bicycle drive comprises the active main drive sprocket (1) that is assemblied in axis, actively is assemblied in the back sprocket wheel (4) of rear axle and is connected in chain (2) between the two; It is characterized in that on the flywheel of back sprocket wheel (4), fixedly being equipped with minor sprocket (6), adapter plate (3) is assemblied on rear axle and the vehicle frame, sprocket wheel (9) is assemblied on the adapter plate (3) with flywheel is coaxial, the coaxial minor sprocket (10) that is equipped with on the flywheel of sprocket wheel (9), back sprocket wheel (4), sprocket wheel (9) and main drive sprocket (1) constitute one pair of transmission by chain (2) and pay, minor sprocket (6), (10) constitute one pair of transmission by chain (7) pays, and sprocket wheel (9) is opposite to the driving direction of flywheel with back sprocket wheel (4) to the driving direction of flywheel.
2, bicycle drive according to claim 1, it is characterized in that idler sprocket (8) fixedly is assemblied in the below of fixing (3), main drive sprocket (1), back sprocket wheel (4), sprocket wheel (9), idler sprocket (8) constitute one pair of transmission by chain (2) and pay.
