Summary of the invention
The utility model has overcome the deficiency of prior art, and a kind of Electrical Bicycle of simple in structure, friction wheel transmission that cost is low is provided.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of Electrical Bicycle of friction wheel transmission; The battery pack that comprises vehicle frame, is installed in front-wheel and trailing wheel, the motor on the vehicle frame and is used for drive motor; Also be provided with friction wheel, said motor and said friction wheel are in transmission connection through chain wheel set, said friction wheel and said front-wheel or trailing wheel frictional transmission.
In preferred embodiment of the utility model; The Electrical Bicycle of friction wheel transmission further comprises on the said vehicle frame and is fixed with installation shaft; Be arranged with electric machine support on the said installation shaft, said electric machine support one end is connected with said motor, and the other end is connected with said friction wheel.
In preferred embodiment of the utility model, the Electrical Bicycle of friction wheel transmission comprises that further said electric machine support is V-shaped, and the kink of said electric machine support wears said installation shaft.
In preferred embodiment of the utility model, the Electrical Bicycle of friction wheel transmission further comprise also comprise stage clip, with stage clip one end bonded assembly trailing cable, the said stage clip other end is connected with said motor.
In preferred embodiment of the utility model, the Electrical Bicycle of friction wheel transmission comprises that further said chain wheel set comprises the minor sprocket that is installed in the motor output shaft end, the hinge wheel that is installed in the friction wheel axle head and the chain that connects minor sprocket and hinge wheel.
In preferred embodiment of the utility model, the Electrical Bicycle of friction wheel transmission comprises that further the side face of said friction wheel has axial groove.
The utility model has solved the defective that exists in the background technology; The utility model has been simplified the structure of transmission device through the type of drive of friction wheel transmission; Not only greatly reduce the manufacturing cost of motor and driving device in the Electrical Bicycle; Wheel hub motor than equal-wattage reduces more than 2/3rds, and transmission is effective, has good economic benefits and social benefit.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the preferred embodiment of the utility model;
Fig. 2 is the structure for amplifying scheme drawing of A among Fig. 1;
Among the figure: 1, vehicle frame, 2, front-wheel, 3, trailing wheel, 4, motor, 5, battery pack, 6, friction wheel, 7, chain wheel set, 8, installation shaft, 9, electric machine support, 10, stage clip, 11, trailing cable, 12, minor sprocket, 13, hinge wheel, 14, chain, 15, axial groove.
The specific embodiment
Combine accompanying drawing and embodiment that the utility model is done further detailed explanation now, these accompanying drawings are the scheme drawing of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Like Fig. 1, shown in Figure 2; A kind of Electrical Bicycle of friction wheel transmission; The battery pack 5 that comprises vehicle frame 1, is installed in front-wheel 2 and trailing wheel 3, the motor 4 on the vehicle frame 1 and is used for drive motor 4; Also be provided with friction wheel 6, said motor 4 is in transmission connection through chain wheel set 7 with said friction wheel 6, wherein; Chain wheel set 7 comprises the chain 14 of the minor sprocket 12 that is installed in motor 4 output axle heads, the hinge wheel 13 that is installed in friction wheel 6 axle heads and connection minor sprocket 12 and hinge wheel 13, said friction wheel 6 and said front-wheel 2 or trailing wheel 3 frictional transmissions.
Be fixed with installation shaft 8 on the preferred said vehicle frame 1 of the utility model, be arranged with electric machine support 9 on the said installation shaft 8, said electric machine support 9 one ends are connected with said motor 4, and the other end is connected with said friction wheel 6.
Said electric machine support 9 is V-shaped, and the kink of said electric machine support 9 wears said installation shaft 8.
For the ease of moving of friction wheel 6; The utility model also comprise stage clip 10, with stage clip 10 1 end bonded assembly trailing cables 11; Said stage clip 10 other ends are connected with said motor 4; Pulling trailing cable 11, stage clip 10 drive motors 4 motions, and motor 4 drives friction wheels 6 through electric machine support 9 and compresses or break away from trailing wheel 3.
In order to prevent skidding between friction wheel 6 and the trailing wheel 3, the side face of said friction wheel 6 has axial groove 15, has improved driving efficiency.
The principle of work of the utility model is following:
Pulling trailing cable 11, stage clip 10 drive motor 4 motions, and electric machine support 9 is that rotate in the center of circle with installation shaft 8; Drive friction wheel 6 compresses trailing wheel 3 and is in normally off, opens battery pack 5, and motor 4 starts; The minor sprocket 12 of motor 4 output axle heads rotates, and the hinge wheel 13 that drives on the friction wheel 6 through chain 14 again rotates friction wheel 6 and trailing wheel 3 frictional transmissions; Because friction wheel 6 differs greatly with the diameter dimension of trailing wheel 3, the transmitting ratio between them can reach 10-15, rotates thereby drive trailing wheel 3.The axial centre plane that friction wheel 6 and chain gear between the motor 4 can make motor 4 and the centre plane of vehicle frame 1 are near overlapping, and motor 4 major parts are embedded in vehicle frame 1 inside.When the electric power of battery pack 5 has been used up, through trailing cable 11 pulling electric machine supports 9, back, trailing cable 9 location is fixing, and friction wheel 6 breaks away from trailing wheel 3 and is in normally open.
Above desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification sheets, must confirm technical scope according to the claim scope.
