Abstract
The utility model relates to a bicycle actuating device comprising a teeth plate (1), a chain (2) and a flywheel (3), the teeth plate is arranged on the centre shaft of the bicycle, the flywheel is arranged on the rear-wheel shaft, and the utility model is characterized in that a intermediate chain wheel (5) is arranged on the flywheel teeth (4) of the flywheel (3), external teeth (6) that located on the round outside of the intermediate chain wheel (5) are inosculated with the chain (2), a circuit inner chain (7) is embedded in the round inside groove of the intermediate chain wheel and is inosculated with the flywheel teeth (4) of the flywheel (3), the chain (2) is arranged on the teeth plate (1) and the flywheel (3), the flywheel teeth (4) of the flywheel (3) are jogged with the inner chain (7) of the intermediate chain wheel (5). The utility model has simple structure, is smooth and steady during the riding, is labor-saving and express, is easy to speed up, and is a novel structure of the current bicycle actuating device.
Description
Technical field
The utility model belongs to mechanical field, relates to driving device, is specifically related to a kind of bicycle drive.
Background technology
Bicycle in the market all adopts the axis chain wheel to rotate by the flywheel that chain drives on the hind axle, realizes advancing of vehicle, and this transmission structures is simple, and is easy to maintenance, but that this driving device also exists riding speed is low, not enough labour-saving defective.
Summary of the invention
The purpose of this utility model is: design a kind of bicycle drive, it simulates multistage type of drive, make ride more laborsaving, faster, low to overcome the speed that existing bicycle drive exists, the defective of the long-distance effort of riding.
Technical solution of the present utility model is: driving device comprises chain wheel, chain and flywheel, chain wheel is installed on the axis of bicycle, flywheel is installed on the hind axle of bicycle, it is characterized in that: the transition sprocket wheel is installed on the flywheel teeth of flywheel, the circle outside of transition sprocket wheel is the external tooth that matches with chain, the inner round side groove of transition sprocket wheel is embedded with the interior chain that a circle and the flywheel teeth of flywheel match, chain is installed on chain wheel and the transition sprocket wheel, the interior chain of the flywheel teeth of flywheel engagement transition sprocket wheel.
When riding, chain wheel rotates and drives chain gear, and chain makes the transition sprocket rotation that is positioned at trailing wheel, rotates thereby the interior chain of transition sprocket wheel drives flywheel again, and bicycle simulation multi-change speed type of drive travels forward.
The utility model is simple in structure, rides steadily, and is laborsaving quick, quicken easily, and be the another new construction of present bicycle drive.
Description of drawings
Fig. 1 is the utility model mounting structure scheme drawing.
Fig. 2 is the transition chain sprocket structure scheme drawing of Fig. 1.
Fig. 3 is the cutaway view of Fig. 2.
Among the figure: 1. chain wheel, 2. chain, 3. flywheel, 4. flywheel teeth, 5. transition sprocket wheel, 6. external tooth, 7. in chain.
The specific embodiment
As shown in Figure 1, 2, 3, driving device comprises chain wheel 1, chain 2 and flywheel 3, chain wheel is installed on the axis of bicycle, flywheel is installed on the hind axle of bicycle, it is characterized in that: transition sprocket wheel 5 is installed on the flywheel teeth 4 of flywheel 3, the circle outside of transition sprocket wheel 5 is the external tooth 6 that matches with chain 2, the inner round side groove of transition sprocket wheel is embedded with the interior chain 7 that a circle and the flywheel teeth 4 of flywheel 3 match, chain 2 is installed on chain wheel 1 and the transition sprocket wheel 3, the interior chain 7 of the flywheel teeth 4 engagement transition sprocket wheels 5 of flywheel 3.
When riding, chain wheel 1 rotates and drives chain 2 transmissions, and chain 2 rotates the transition sprocket wheel 5 that is positioned at trailing wheel, rotates thereby the interior chain 7 of transition sprocket wheel 5 drives flywheel 3 again, and bicycle simulation multi-change speed type of drive travels forward.
Claims (1)
