The part that stub 5 in the described electric drive cooperates with minor sprocket 3 is provided with flat key 12, forms adaptive being slidingly matched with minor sprocket 3, makes minor sprocket 3 and chain 8 be in work in the same plane all the time.
The part that cooperates with minor sprocket 3 of the stub 5 in the described electric drive is the flat axle, forms adaptive being slidingly matched with minor sprocket 3, makes minor sprocket 3 and chain 8 be in work in the same plane all the time.
Effect of the present utility model be this structure respectively in manpower and electric drive, adopted automatic adaptation sliding engaged drive mechanism, sprocket wheel and stub and sprocket wheel have adopted the self adaption fit system that can axially be free to slide with during output shaft cooperates.So guarantee sprocket wheel and chain, locate all the time to work at grade, make the chain at a high speed and in the transmission of vibration, effectively prevented in the engagement driving take off chain and catching phenomenon takes place, and greatly improve transmission efficiency.

Embodiment
Reach in conjunction with the accompanying drawings that embodiment makes up double dynamical transmission gear shift box structure to gear-sprocket wheel of the present utility model and course of action is illustrated.
As shown in Figure 1, 2, gear-sprocket wheel of the present utility model makes up double dynamical transfer gear box, and its electric drive is formed the one-level gear transmission by gear 1, driving gear 2, and small gear 1 connects with the electric power axle is coaxial, and slows down through driving gear 2; The sprocket driving that the secondary transmission adopts minor sprocket 3, hinge wheel 4 to form, minor sprocket 3 connects by stub 5 with driving gear 2, and connect with hinge wheel 4 by chain 8, hinge wheel 4 and output shaft 10, minor sprocket 7 are coaxial, and minor sprocket 7 passes through chain 9 and connects with hinge wheel 6; Sprocket driving is also adopted in the manpower transmission, is connected people's mechanical axis 11 and 6 coaxial connections of hinge wheel, soon one group of speed change gear gear 1, driving gear 2 and two groups of speed-changing chain minor sprockets 3, hinge wheel 4 by chain 9 by hinge wheel 6, minor sprocket 7; Minor sprocket 7, hinge wheel 6 organically combine one and constitute speed reducer.Hinge wheel 4 and hinge wheel 6 adopt flywheel structure, reach electric power effect, manpower effect, manpower and electric power acting in conjunction by flywheel and realize three kinds of driving force kinds of drive.One end of the output shaft 10 in the described manpower transmission is set to the flat axle, forms with minor sprocket 7 to be slidingly matched, and minor sprocket 7 and chain 9 are in the same plane all the time.When electric drive, output to output shaft 10 by double reduction (gear, sprocket wheel), at this moment, the flywheel of hinge wheel 6 and axis are thrown off, and people's mechanical axis 11 is inoperative, thereby realizes electric drive.When the manpower transmission, hinge wheel 6 reaches output shaft 10 by chain 9, and at this moment, power transmission system is thrown off by the flywheel and the output shaft 10 of hinge wheel 4, and the electric power axle does not act on, and realizes that manpower drives.When electric power, manpower acting in conjunction, the flywheel of hinge wheel 4 and hinge wheel 6 locks simultaneously, and electric power, manpower are sent to output shaft 10 simultaneously, realize double dynamical driving.Hinge wheel 4, hinge wheel 6 are selected flywheel for use, and hinge wheel 4 is preferably selected the fine pith flywheel for use.
Shown in Fig. 3,4, the part that the stub 5 in described electric drive cooperates with minor sprocket 3 is provided with flat key 12, forms adaptive being slidingly matched with minor sprocket 3, makes minor sprocket 3 and chain 8 be in work in the same plane all the time.The part that cooperates with minor sprocket 3 of stub 5 that also can be in electric drive is the flat axle, forms adaptive being slidingly matched with minor sprocket 3, minor sprocket 3 and chain 8 is in all the time on same the plane in works.So just changed axle and adopted fixed linkage structure usually with sprocket wheel.
In a word, the utility model in manpower and electric drive, has adopted automatic adaptation sliding engaged drive mechanism respectively, and sprocket wheel 3 and stub 5 and sprocket wheel 7 have adopted the fit system that can axially be free to slide with during output shaft 10 cooperates.So guarantee sprocket wheel and chain, locate all the time to work at grade, make the chain at a high speed and in the transmission of vibration, effectively prevented in the engagement driving take off chain and catching phenomenon takes place, and greatly improve transmission efficiency.
