Abstract
The utility model relates to a gear driving chainless bicycle driving gear, which is char a middle shaft is arranged in a bearing of a five whole body; a conical gear is fixed on the middle shaft and is engaged with a conical gear in the five whole body; a shaft bar of the conical gear is matched with a transmission shaft; a back conical gear matched with the tail end of the transmission shaft is engaged with a back driving conical gear on a back shaft; a flywheel is driven by the back driving conical gear to forwards rotate.
Description
The utility model belongs to the improvement of bicycle drive.
Traditional bicycle kind of drive adopts the sprocket wheel chain structure, and existing shortcoming is: grade climbing performance is relatively poor, is prone to fault.
The purpose of this utility model is the shortcoming at above-mentioned existence, and a kind of gear transmission chainless driving device for bicycle is provided, and it is little that this device has moment of rotation, the characteristics of be difficult for breaking down, grade climbing performance is higher.
The purpose of this utility model is achieved in that the gear transmission chainless driving device for bicycle is made up of structures such as five-way, axis, Bevel Gear Drive, wherein axis is installed in the bearing of five-way body, cone gear be fixed on the axis with the five-way body in the cone gear engagement, the cone gear axostylus axostyle cooperates with transmission shaft, back cone gear that cooperates with the transmission shaft tail end and the rear driving cone gear engagement that is installed on the rear axle drive flywheel by the rear driving cone gear and rotate forward.
The utlity model has simple in structure, easy to install, manufacture cost is lower, the transmission output torque is big, is difficult for breaking down, grade climbing performance is higher.
In conjunction with the accompanying drawings structure of the present utility model is described further.
Fig. 1 is the utility model structural principle sectional drawing.
Fig. 2 is the utility model rear drive configuration principle sectional drawing.
Fig. 1, the 2nd, embodiment of the present utility model.
With reference to Fig. 1,2, the gear transmission chainless driving device for bicycle is made up of drive mechanisms such as five-way 3, axis 1, cone gears, wherein axis 1 is installed in the bearing 12 of five-way 3 bodies, cone gear 4 be fixed on the axis 1 with five-way 3 bodies in cone gear 6 engagements, cone gear 6 axostylus axostyles cooperate with transmission shaft 9, back cone gear 18 that cooperates with transmission shaft 9 tail ends and rear driving cone gear 20 engagements that are installed on the rear axle 13 drive flywheel 24 by rear driving cone gear 20 and rotate forward.
Claims (1)
1, a kind of gear transmission chainless driving device for bicycle, form by five-way, axis, Bevel Gear Drive structure, it is characterized in that axis is installed in the bearing of five-way body, cone gear be fixed on the axis with the five-way body in the cone gear engagement, the cone gear axostylus axostyle cooperates with transmission shaft, back cone gear that cooperates with the transmission shaft tail end and the rear driving cone gear engagement that is installed on the rear axle drive flywheel by the rear driving cone gear and rotate forward.
