The motor output transmission mechanism comprises a motor output shaft, a primary output gear arranged on a motor output shaft, a secondary output gear meshed with the primary output gear, and the middle shaft connected with the secondary output gear in a sleeve mode. The chain wheel mechanism comprises a driving chain wheel arranged on the middle shaft, an output chain wheel arranged on the middle shaft, a tensioner chain wheel used for tensioning adjustment of the output chain wheel, and a driven chain wheel. All the chain wheels of the chain wheel mechanism are arranged on the same plane. An overrun clutch I is arranged between the driving chain wheel and the middle shaft. An overrun clutch II is arranged between the middle shaft and the output chain wheel. The inner-mounted motive power device for the electric bicycle is simple in structure. Meanwhile, a dynamic drive mechanism and the manpower driving mechanisms are separately arranged and the reliability of the motive power output is higher.

Summary of the invention
In view of this, the purpose of the utility model provides a kind of Electrical Bicycle simple in structure, that reliability is higher and uses mid-engine installation.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of Electrical Bicycle is used mid-engine installation; Comprise man power driving mechanism and chain-wheel mechanism that the output of motor, motor transmission device, housing, the axis that passes housing, axis two ends are fixedly connected, said motor output transmission device comprise the one-level output gear that is provided with on motor output shaft, the motor output shaft, with the tween drive shaft of one-level output gear ingear secondary output gear and socket secondary output gear; Said chain-wheel mechanism comprises the output chain gear that is provided with on the drive sprocket that is provided with on the axis, the tween drive shaft, is used for idler sprocket and driven sprocket that the output chain gear tensioning is regulated; All sprocket wheels of said chain-wheel mechanism all at grade; Be provided with overriding clutch I between said drive sprocket and the axis; Be provided with overriding clutch II between said tween drive shaft and the output chain gear.
Said housing comprises gear box casing and electric machine casing, said gear box casing and the moulding of electric machine casing integral die-cast.
Be marked with lubricating oil in the said gear box casing.
The beneficial effect of the utility model is: a kind of Electrical Bicycle of the utility model has simple in structure, compact and lower-cost advantage with mid-engine installation; The planeness of each parallelism and chain-wheel mechanism all is further enhanced; Electric driving mechanism and man power driving mechanism split are provided with; The reliability of its takeoff output is higher, the difficult generation phenomenon that gets stuck, and also lubricant effect is better.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
