Abstract
The utility model discloses a chainless bicycle; a sprocket (2) is arranged between a chain wheel (1) of a middle shaft of a bicycle and a flywheel (3) of a rear shaft by a bearing (7); a tooth buckle (5) of the sprocket is arranged on the outer circumference of the sprocket (2); the tooth buckle (5) of the sprocket is mutually engaged with teeth (4) of the chain wheel and teeth (6) of the flywheel. When people ride the bicycle, the rotating chain wheel of the middle shaft drives a sprocket to drive; then, the sprocket enables the flywheel positioned at the rear wheel to rotate; the bicycle move forwards and simultaneously realizes chainless transmission. The utility model enhances transmission stability and reduces friction surfaces, with labor saving and quickness; the transmission device with a new structure realizes chainless transmission.
Description
Affiliated technical field
The utility model relates to bicycle, is specifically related to chain-less bicycle.
Background technology
At present, the bicycle on the market all adopts the axis chain wheel to drive flywheel rotation on the trailing wheel by chain, realizes advancing of vehicle, and it is low that this chain gear bicycle exists riding speed, not enough labour-saving defective.
Summary of the invention
The purpose of this utility model is: a kind of chain-less bicycle is provided, adopts sprocket wheel to substitute the drive method of chain, make ride laborsaving quick.
Technical solution of the present utility model is: a sprocket wheel is installed between the axis chain wheel of bicycle and rear flywheel, is established the tooth button on this sprocket wheel excircle, tooth button and chain wheel teeth and flywheel teeth are meshing with each other.
When riding, the transmission of axis chain wheel rotating band movable sprocket, sprocket wheel rotates the flywheel that is positioned at trailing wheel, and bicycle travels forward, and realizes no chain gear.
The utility model has improved transmission stability, has reduced attrition surface, and laborsaving quick, the driving device of this new construction has been realized no chain-driving.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure: 1 axis chain wheel, 2 sprocket wheels, 3 rear flywheels, 4 chain wheel teeth, 5 sprocket buttons, 6 flywheel teeth, 7 bearings
The specific embodiment
As shown in Figure 1, establish sprocket button 5 at the axis chain wheel 1 and 3 of the rear flywheels of bicycle on the excircle of this sprocket wheel 2 by bearing 7 installations one sprocket wheel 2, sprocket button 5 is meshing with each other with chain wheel teeth 4 and flywheel teeth 6.
Drive sprocket wheel 2 when axis chain wheel 1 rotates, sprocket wheel 2 drives rear flywheel 3 and rotates, and flywheel rotates realizes that bicycle advances.
Claims (2)
