The utility model has the advantages of simple structure, compactness, material saving, light weight, convenient installation and convenient maintenance; the utility model is suitable for the reform of ordinary pedal bicycles.
Description
The utility model belongs to the Electrical Bicycle driving device, shaft drive in particularly a kind of Electrical Bicycle.
At present the Electrical Bicycle driving device all is arranged near the hind axle, be one with footstep mechanism mechanism independently mutually, increase to two mechanisms like this, making complicated integral structure has increased weight.The purpose of this utility model provides shaft drive in a kind of Electrical Bicycle, overcomes the shortcoming and defect of prior art, reaches the minimizing parts, and simplified structure alleviates the purpose of complete machine weight.
The purpose of this utility model is achieved in that
Shaft drive in a kind of Electrical Bicycle, by body, casing that cover is formed and casing in-to-in transmission device are formed, it is characterized by: the in-to-in transmission device is, one side of casing is and miniature electrical machinery axle bonded assembly axis hole, this axis hole is other to be a transmission shaft, the two axial ends connection bearing of a transmission shaft, this bearing fixing is at the body of casing, on the cover, be fixed with the big gear wheel that is meshed with miniature gears on the miniature electrical machinery axle on transmission shaft, also be fixed with minor sprocket on the transmission shaft, at the other secondary transmission shaft in addition of transmission shaft, the secondary transmission shaft is also referred to as the output coupling spindle, secondary transmission shaft two axial ends connection bearing, this bearing fixing is at the body of casing, on the cover, secondary transmission shaft one end passes outside the cover, be fixed with flywheel and sprocket wheel on the secondary transmission shaft, minor sprocket on this flywheel and the transmission shaft in one plane, this flywheel is connected chain with minor sprocket on transmission shaft, the secondary transmission shaft is other to be axis, the two ends connection bearing of axis, this bearing fixing is at the body of casing, on the cover, the two ends of axis pass casing body, outside the cover, be fixed with flywheel on the axis, sprocket wheel on this flywheel and the secondary transmission shaft is connected with chain on the sprocket wheel on its flywheel and the secondary transmission shaft on a plane.
Pass an end fixed chain wheels of the outer secondary transmission shaft of cover.On the axle of a side of fixing flywheel axle sleeve is arranged on the axis.
The outline of being made of casing body, cover is avette
The utility model has the advantages that:
Simple in structure, compactness, economical with materials, in light weight, easy for installation, easy to maintenance, be suitable for the transformation of general bicycle.
Below in conjunction with description of drawings embodiment:
Fig. 1 is an Electrical Bicycle axis transmission structures cutaway view
Fig. 2 is a shaft drive outside drawing in the Electrical Bicycle
Shaft drive in a kind of Electrical Bicycle, by the casing that body 1, cover 2 are formed, the outline of casing is avette.Casing is an avette flat box body.Casing inside is that transmission device is formed, the in-to-in transmission device is, one side of casing is and 34 bonded assembly axis holes 5 of miniature motor, this axis hole is other to be a transmission shaft 6, the two axial ends connection bearing 7 of a transmission shaft, 8, this bearing fixing is at the body of casing, on the cover, be fixed with the big gear wheel 10 that is meshed with miniature gears 9 on the miniature electrical machinery axle on transmission shaft, also be fixed with minor sprocket 11 on the transmission shaft, at the other secondary transmission shaft 12 in addition of transmission shaft, the secondary transmission shaft is also referred to as the output coupling spindle, secondary transmission shaft two axial ends connection bearing 13,14, this bearing fixing is at the body of casing, on the cover, secondary transmission shaft one end passes outside the cover, be fixed with flywheel 15 and sprocket wheel 16 on the secondary transmission shaft, minor sprocket on this flywheel and the transmission shaft in one plane, this flywheel is connected chain 17 with minor sprocket on transmission shaft, the secondary transmission shaft is other to be axis 18, the two ends connection bearing 19 of axis, 20, this bearing fixing is at the body of casing, on the cover, the two ends of axis pass casing body, outside the cover, be fixed with flywheel 21 on the axis, sprocket wheel on this flywheel and the secondary transmission shaft is connected with chain 22 on the sprocket wheel on its flywheel and the secondary transmission shaft on a plane.
Pass an end fixed chain wheels 23 of the outer secondary transmission shaft of cover.On the axle of a side of fixing flywheel axle sleeve 24 is arranged on the axis.
But pass casing two ends a connection pin of the outer axis of body, cover pedal son.
The fixed chain wheels that passes outer secondary transmission shaft one end of cover is by the flywheel on the chain connection rear vehicle shaft.
