Background technology
Mainly there is following shortcoming in battery-operated motor cycle in the market: what one, adopt is the work of motor direct-drive trailing wheel, the transmission of motor is from zero turn-off beginning work, according to the machine operation principle, work drive motor must overcome rotor inertia and wheel and the acting of ground-surface resistance of self under slow speed of revolution, so the consumption of current of this motor in motor bike starting-up to speed process is very big, electric current is also very big, and waste of energy very; Two, motor is installed in the trailing wheel, does not have radiating gill and fan, and heat dispersion is poor, and the motor bearings lubricity is poor, and motor is short service life; Three,,, can not satisfy the requirement of motorcycle driving so that car load speed is carried is not high because the oad of motor and the restriction of structure make the power of motor not increase; Four, because motor is installed in the trailing wheel, cause after the entrucking car load center of gravity partially after, the driving safety performance is poor.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of battery-operated motor cycle power take-off implement, and this battery-operated motor cycle power take-off implement can saving in energy, improve the heat dispersion of motor, and the safety that can improve vehicle '.
The utility model provides a kind of battery-operated motor cycle power take-off implement, comprise motor, self-acting clutch mechanism, tire output shaft, described tire output shaft outside socket tire, described motor is installed in a side of described tire output shaft by connecting panel, and described motor drives described tire output shaft by chain assemblies and rotates.
Described motor comprises stator and rotor, described stator and described rotor-bearing free-running fit, and described two ends of rotor is stretched out outside the described stator, is combined with self-acting clutch mechanism at the external part suit of described rotor one side.
Described self-acting clutch mechanism comprises driving disc spacing pressing and clutch plate, is provided with clutch spring on described driving disc spacing pressing, and described clutch spring is connected with clutch friction hoof piece.
External part at described rotor opposite side is provided with tube axial fan.
The outside at described motor, self-acting clutch mechanism, chain assemblies is provided with casing.
Be provided with free-wheel clutch at described tire output shaft and described chain assemblies junction.
Because said structure of the present utility model improves, and has following characteristics and advantage:
1, motor is installed in a side of tire output shaft by connecting panel, guarantees the center of the entrucking center of gravity of vehicle at vehicle.
2, adopted automatic clutch device, this power-transfer clutch is just started working when 2000 change, and the motor rotor inertia can be stored on the hoof piece of self-acting clutch like this, and the hoof piece has energy-storaging spring, is converted into available kinetic energy output then, conserve energy.
3, the motor other end increases tube axial fan, and heat dispersion improves greatly.

The specific embodiment
As shown in Figure 1, the utility model battery-operated motor cycle power take-off implement, comprise motor, self-acting clutch mechanism, tire output shaft 19,, tire output shaft 19 outside socket tires 16, motor is installed in a side of tire output shaft 19 by connecting panel 20, and motor drives 19 rotations of tire output shaft by the chain assemblies of being made up of driving chain 12, chain tension device 11.
Motor comprises stator 4 and rotor 5, and stator 4 cooperates with rotor 5 bearing spaces, and stretch out outside the stator 4 at rotor 5 two ends, is combined with self-acting clutch mechanism at the external part suit of rotor 5 one sides.Self-acting clutch mechanism comprises driving disc spacing pressing 9, clutch plate 7, clutch spring 10 and clutch friction hoof piece 8, is provided with clutch spring 10 on driving disc spacing pressing 9, and clutch spring 10 is connected with clutch friction hoof piece 8.
External part at the opposite side of rotor 4 is provided with tube axial fan 1.Be provided with casing 3,15 in the outside of motor, self-acting clutch mechanism, chain assemblies.Be provided with free-wheel clutch 13 in tire output shaft 19 and chain assemblies junction.
The utility model is through following improvement: one, motor is mounted on the casing 15 of a rigidity, automatic clutch device has been adopted in elementary transmission (driving wheel), this power-transfer clutch is just started working when 2000 change, the motor rotor inertia can be stored on the hoof piece 8 of self-acting clutch like this, the hoof piece has energy-storaging spring 10, be converted into available kinetic energy output then, conserve energy; The inner free-wheel clutch 13 that adopts of driven sprocket makes behind the vehicle launch that coasting ability improves automatically, is not subjected to the influence of motor self rotor inertia antagonistic force, and motor still can utilize rotor inertia to keep unloaded and rotate; Thereby be that a large amount of electric energy is saved in follow-up acceleration; Two, motor is independent, not in trailing wheel inside, the motor other end increases tube axial fan 1, heat dispersion improves greatly, and transmission adopted machine oil is directly lubricated, and each bearing lubrication is functional, motor left end bearing is an oil lubricating, right-hand member has the oil nozzle that can add butter, can guarantee to obtain to lubricate fully, thus the service life of improving motor greatly; Three, motor designs for absolute construction, is not subjected to shape limitation, can improve the battery-driven car speed of a motor vehicle greatly with the power of motor design maximum to 3000W, makes battery-operated motor cycle and petrol power motor bike compare favourably; And adopted self-acting clutch, the vehicle speed-raising is steadily controlled freely; Four, electric machine design is at front end, and the entrucking center of gravity that guarantees vehicle has been reserved the position that trailing wheel is installed hydraulic brake simultaneously in the center of vehicle, fully guarantees the safety of vehicle '.
