Description
Technical field
Patent of the present invention relates to a kind of motor driver that is used for LEV (Light Electric Vehicle), is applicable to the LEV (Light Electric Vehicle) (not comprising Electrical Bicycle) that battery-operated motor cycle is above, belongs to electronic product engine installation field.
Background technology
Present domestic all battery-operated motor cycle motor drivers, all be to adopt the slowspeed machine direct drive, for example: the low-speed brushless motor actuating device, low speed brush motor actuating device, its typical structure as shown in Figure 1, wherein 1 is wheel hub, the outer rotor 2 of motor is fixedly mounted in the wheel hub 1, tire 4 rotates with motor outer rotor 2 and wheel hub 1, and the 3rd, motor stator, its anchor shaft 5 is fixed on the vehicle frame 6.This class slowspeed machine, again can't improve owing to be subjected to the restriction of principle and constructional feature because coil is many, and internal resistance is big, so poor performance, and electrical efficiency only can reach 70～75%, and mechanical specialities β value only can reach 12～15 (rpm/Nm).In actual use, show as hill climbing ability poor (output torque is little), continual mileage short (the flat pavement running electric current is big) becomes the developing technical bottleneck of battery-operated motor cycle.
Summary of the invention
The objective of the invention is to propose a kind of motor driver that is used for LEV (Light Electric Vehicle), the method that adopts the direct current high-speed electric expreess locomotive to combine with gear reduction, be that efficient rare-earth DC disc type electric machine and efficient gear train assembly combine, so that the hill climbing ability of actuating device is strong, continual mileage is far away.
The motor driver of the LEV (Light Electric Vehicle) that the present invention proposes has two kinds of structures, and first kind of structure wherein comprises motor, driving system and cabinet; Described motor is installed on the casing, and driving system places in the casing, and links to each other with the wheel hub of casing battery-driven car wheel outward; Described driving system comprises miniature gears, intermediate gear, big gear wheel and overriding clutch, and miniature gears links to each other with the output shaft of motor, and miniature gears is by intermediate gear and big gear wheel interlock, and big gear wheel links to each other with the axle drive shaft of battery-driven car by overriding clutch.
Second kind of structure comprises motor, driving system; Described motor is installed in outside the wheel hub of battery-driven car tire, and driving system is fixed on the interior anchor shaft of battery-driven car tire wheel hub; Described driving system comprises miniature gears, intermediate gear, big gear wheel and overriding clutch, described miniature gears links to each other with the output shaft of motor by pipe link, by intermediate gear and big gear wheel interlock, described big gear wheel links to each other with battery-driven car tire wheel hub by overriding clutch simultaneously.
The motor driver of the LEV (Light Electric Vehicle) that the present invention proposes, its biggest advantage is that its mechanical specialities is hard especially, the battery-operated motor cycle wheel of existing slowspeed machine formula, rotating speed is 530rpm when idle running, add normal load (10Nm), rotating speed drops to 400rpm at once, reduces and 130 to change (to be equivalent to β=13rpm/Nm), mechanical specialities " soft "; With the electricity of the motor driver of the present invention configuration tire that rubs, rotating speed is 420rpm when idle running, adds same normal load (10Nm), and rotating speed drops to 400rpm, and rotating speed only descends 20 to be changeed (is equivalent to β=2rpm/Nm), mechanical specialities " firmly ".As can be seen, the β value is more little, and characterization is hard more.For actuating device, series of advantages such as characteristic firmly just means power saving, and hill climbing ability is strong, and continual mileage is far away; For slowspeed machine, it is higher to pursue efficient merely, and (also being difficult to reach very high), but definitely can't improve its mechanical specialities β value.
Actuating device of the present invention in the power range of 400～2000W, adapts with the power of various LEV (Light Electric Vehicle), and its system effectiveness can be near 90%, and its mechanical specialities β value can reach 2 (rpm/Nm).This is the present still irrealizable effect of the actuating device of other form aspect LEV (Light Electric Vehicle).Therefore, this novel driving device has outstanding result of use in the actuation techniques of present LEV (Light Electric Vehicle).
