Abstract
The utility model discloses a magneto-motive efficient dynamic driving device of an electric bicycle. The magneto-motive efficiency dynamic driving device comprises an electric motor, a driving wheel connected with the electric motor, a driven wheel and bicycle rear wheels arranged on the two sides of the driven wheel. A set of first permanent magnets is arranged on the driving wheel, a second set of second permanent magnets is arranged on the driven wheel, and the magnetic poles, facing the wheel center, of the first permanent magnets and the magnetic poles, facing the wheel center, of the second permanent magnets are the same. According to the magneto-motive efficient dynamic driving device of the electric bicycle, the bicycle rear wheels are in seamless connection with the driven wheel coaxially, namely, gaps between the driven wheel and the two rear wheels are very small and can be ignored; through the structural design, influences to the stability when the electric bicycle swerves are relatively small; if the gaps are too large or only a single wheel is provided, stress is imbalanced during swerving, the bicycle is prone to being out of control, and accordingly the safety of a rider is affected; electric energy is saved and the electric energy is saved by 10%-15% compared with a traditional electric vehicle.
Description
Technical field
The utility model discloses a kind of bicycle driving device, be specifically related to a kind of Electrical Bicycle magnetic motive force high-efficiency dynamic actuating device.
Background technology
Existing Electrical Bicycle adopts gear transmission mostly, and some power wastage of this transmission is in the friction between gear, and gear wear is more serious, easily gear is caused to damage.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of Electrical Bicycle magnetic motive force high-efficiency dynamic actuating device.
Technical scheme: for solving the problems of the technologies described above, a kind of Electrical Bicycle magnetic motive force high-efficiency dynamic actuating device that the utility model provides, comprise electro-motor, the driving wheel connecting with electro-motor, flower wheel and the bicycle rear that is located at flower wheel both sides, described driving wheel is provided with one group of first permanent magnetic iron, described flower wheel is provided with one group of second permanent magnetic iron, and the first permanent magnetic iron is identical to the magnetic pole of core wheel direction with the second permanent magnetic iron.
Further, between electro-motor and driving wheel, can be connected by coaxial, also can disalignment connect.
Further, described bicycle rear is realized coaxial seamless link with flower wheel by bearing.
Further, described the first permanent magnetic iron and the second permanent magnetic iron are located at respectively the circumference place of driving wheel and flower wheel.
Further, in order to extend the service life of actuating device and the overall appearance of whole Electrical Bicycle, described driving wheel and flower wheel are provided with a box by aluminum alloy or copper production outward.
When the utility model is worked when electro-motor, electro-motor drives driving wheel rotation, the principle that driving wheel repels each other by same pole promotes flower wheel and rotates, flower wheel rotates by the repulsion driving electric bicycle rear of the homopolarity magnetic of inertia and driving wheel, thereby drives Electrical Bicycle to move ahead.
Beneficial effect: the utility model is that gap between flower wheel and two trailing wheels is very little, negligible by the coaxial seamless link of bicycle rear and flower wheel; When the design of this structure is turned at Electrical Bicycle, be affected relatively can be smaller for stability, if gap is excessive or only have single-wheel, discontinuity equalization during turning, is easy to cause bicycle out of control, thereby affects cyclist's safety; And saving electric power, compared with traditional electrical motor-car, save electric power 10% ~ 15%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of Electrical Bicycle magnetic motive force high-efficiency dynamic actuating device, comprise electro-motor 1, the driving wheel 3 connecting with electro-motor 1, flower wheel 6 and the bicycle rear 7 that is located at flower wheel 6 both sides, described driving wheel 3 is provided with one group of first permanent magnetic iron 2, it is identical to the magnetic pole of core wheel direction with the second permanent magnetic iron 4 that described flower wheel 6 is provided with one group of second permanent magnetic iron, 4, the first permanent magnetic irons 2; Described bicycle rear 7 is realized coaxial seamless link with flower wheel 6 by bearing 5; Described the first permanent magnetic iron 2 and the second permanent magnetic iron 4 are located at respectively the circumference place of driving wheel 3 and flower wheel 6; Described driving wheel 3 and the outer box by aluminum alloy or copper production that is provided with of flower wheel 6.The quantity of described the first permanent magnetic iron 2 and the second permanent magnetic iron 4 is generally 2 ~ 8.
The utility model is when electro-motor 1 work, electro-motor 1 drives driving wheel 3 rotations, the principle that 3 of driving wheels repel each other by same pole promotes flower wheel 6 and rotates, 6 repulsion driving electric bicycle rear 7 rotations by the homopolarity magnetic of inertia and driving wheel 3 of flower wheel, thus drive Electrical Bicycle to move ahead.The utility model can be saved electric power, compared with traditional electrical motor-car, saves electric power 10% ~ 15%.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
