The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1-Fig. 6 is respectively the scheme drawing of giving power driving disk, drive system model and chain wheel drive system in the driving system that the present invention proposes.
The driving system of the Electrical Bicycle that the present invention proposes; Comprise motor 6, Electrical Bicycle drive sprocket 7, through chain and said Electrical Bicycle drive sprocket 7 bonded assembly Electrical Bicycle driven sprockets 14, axis 9, with said axis 9 bonded assembly stretchers 10, and to the power driving disk;
As depicted in figs. 1 and 2; Said interior cover 1, middle cover 2 and the overcoat 3 of comprising radially stack for the power driving disk, said in cover 1 form firsts clutch 4 with middle cover 2, said in cover 2 form second clutch 5 with overcoat 3; Said first clutch 4 is a free-wheel clutch with second clutch 5
Said overcoat 3 is connected with said motor 6 through drive system;
The driving system of Electrical Bicycle provided by the invention; Adopt interior cover 1, middle cover 2 and the overcoat 3 of radially stack to form to the power driving disk; Driving efficiency simple in structure, as also to have improved Electrical Bicycle simultaneously; Not disturbing mutually when reducing manpower and driven by power reduced the energy loss and the wasting of resources.
Wherein, the drive system in the foregoing description can be sent to overcoat 3 with the propulsive effort that guarantees motor for the drive system of drive system model or sprocket drive system and other transmission motor-driven energy.
Like Fig. 3 and shown in Figure 4; In the present invention; Said drive system model comprise drive motor driving gear 11 and with the drive motor driven gear 12 of drive motor driving gear 11 interlocks; Said drive motor driving gear 11 is connected with output drive strength with the motor shaft of said motor 6, and said drive motor driven gear 12 connects said overcoat 3 through bolt 8.
Fig. 5 and Fig. 6 show is the structural representation of chain wheel drive of the present invention system; Said chain wheel drive system comprises drive motor drive sprocket 11 ' and through chain and said drive motor drive sprocket 11 ' bonded assembly drive motor driven sprocket 12 '; Said drive motor drive sprocket 11 ' is connected with output drive strength with the motor shaft of said motor 6, and said drive motor driven sprocket 12 ' connects said overcoat 3 through bolt 8.
In addition, do not disturb mutually in order to make manpower and motor-driven further, the stop direction of said first clutch 4 and second clutch 5 is preferably opposite.
Among the present invention, the driving system of said Electrical Bicycle also comprises the motor decelerating mechanism 13 that is arranged between said drive system and the said overcoat, and it can control the propulsive effort that motor exports overcoat to, to reach the purpose of the control speed of a motor vehicle.
Be the working process that example is explained the driving system of Electrical Bicycle of the present invention with chain wheel drive of the present invention system below:
When manpower drives; In being sent to through the axis 9 of captiveing joint with stretcher 10, foot-operated power overlaps on 1; Because cover 2 during the effect of first free-wheel clutch 4, propulsive effort are passed to by interior cover 1 outputs to Electrical Bicycle drive sprocket 7; Drive Electrical Bicycle driven sprocket 14 through chain, move ahead thereby order about Electrical Bicycle.And second clutch 5 was in and surmounted state this moment; Middle cover 2 rotations, overcoat 3 keeps quiescences, and middle cover 2 has no interaction relation with overcoat 3; Thereby can not drive motor 6 and drive the 11 ' rotation of drive motor drive sprocket, just can not drive the resistance that Electrical Bicycle brings motor yet to manpower.
In the time of driven by power; The output shaft of motor 6 drives drive motor drive sprocket 11 ' and drive motor driven sprocket 12 ' through chain, and the propulsive effort of output drives overcoat 3 rotations, because the effect of second clutch 5; Cover 2 during propulsive effort is sent to by overcoat 3; Output to Electrical Bicycle drive sprocket 7, drive Electrical Bicycle driven sprocket 14, move ahead thereby order about Electrical Bicycle through chain.And first clutch 4 was in and surmounted state this moment, middle cover 2 rotations, and interior cover 1 keeps quiescence, and middle cover 2 has no interaction relation with interior cover 1, thereby can not drive axis 9 and stretcher 10 rotations, also just can not additive decrementation electric power.
When the manpower driving needs motor power-assisted or motor-driven to need manpower power-assisted, according to the principle of free-wheel clutch, at this moment; In do not have relative motion between the cover 1, middle cover 2, overcoat 3; First clutch 4 drives manpower and is sent on the middle cover 2, and second clutch 5 overlaps on 2 in also being sent to motor-driven power, as long as cover 1 rotating speed is not less than middle cover 2 rotating speeds in the maintenance manually driven; Cover 2 rotating speeds during power-actuated overcoat 3 rotating speeds are not less than; Just can reach manpower and motor-driven power can combined action in middle cover 2, thereby drive Electrical Bicycle drive sprocket 7, send Electrical Bicycle driven sprocket 14 to through chain; Order about Electrical Bicycle jointly and move ahead, realized power-assisted purpose.
When drive system was drive system model, except that the overcoat 3 and the connection mode of motor 6 are gear is connected, other structure and the power delivery mode all working process with foregoing description were identical, were not therefore giving unnecessary details here.Will be appreciated that simultaneously the use to the power driving disk of the present invention does not receive the influence of the concrete installation site of motor 6.
The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention; If do not break away from the spirit and scope of the present invention, the present invention is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of claim of the present invention.
