Description
Technical field
The present invention relates to the battery-operated motor cycle parts, be specifically related to two grades of automatically controlled variable speed electric motors, particularlies of a kind of battery-operated motor cycle.
Background technology
Because fuel motorcycle discharge tail gas contaminated environment, in recent years, it is the battery-operated motor cycle of the energy that people have developed with the storage battery.Like hub-type electric motorcycle, the drive motors of this battery-operated motor cycle is installed in the center of rear-wheel hub, directly drives trailing wheel; Though fuel consumption is not of value to environmental protection; But not enough below existing: the one, climbing power is not enough, and the 2nd, flat pavement running speed is slow.In order to overcome the defective that hub-type electric motorcycle exists, people have developed the battery-operated motor cycle of mechanical speed change again, and the name of announcing like CN 200977974Y is called " a kind of battery-operated motor cycle of shift ".This battery-operated motor cycle is on the basis of fuel motorcycle structure; Change fuel tank into power supply box, supporting with high speed DC electric motor and gearbox, as the power engine of battery-operated motor cycle; It is installed in the middle and lower part of vehicle body, drives trailing wheel through the chain gear transmission assembly and rotate.Though this battery-operated motor cycle can pass through the speed governing of mechanical system shift, structure is complicated, not compact, and the heat radiation of high speed DC electric motor is bad, and motor is short useful life, and manufacturing cost is high.Therefore, also need fundamentally to solve the problem that exists.
Summary of the invention
The purpose of this invention is to provide two grades of automatically controlled variable speed electric motors, particularlies of a kind of battery-operated motor cycle, its structure is simple and clear, compact, and gear-change operation is convenient, reliable, good heat dissipation effect not only, and long service life, and processing and manufacturing easily, cost is lower.
Two grades of automatically controlled variable speed electric motors, particularlies of a kind of battery-operated motor cycle of the present invention; Comprise housing, be located at motor stator on the inner walls, through the bearing location be connected motor shaft in housing, be located on the motor shaft left part and the rotor corresponding with motor stator, it is characterized in that:
On the right part of said motor shaft, be provided with initiatively I shelves gear, active II shelves gear and freewheel clutch from right to left successively; Initiatively I shelves gear is connected by spline fitted with motor shaft; Initiatively II shelves gear sky is enclosed within on the motor shaft and is connected with the side of the body of freewheel clutch; The center cams of freewheel clutch connects by spline fitted with motor shaft and is corresponding with the electromagnet that is located on the housing, and this magnet spool is connected with dc source by lead and through the shift switch;
One intermediate gear shaft is connected in housing through the bearing location; On this intermediate gear shaft, be provided with driven I shelves gear, driven II shelves gear and driving pinion from right to left successively; Driven I shelves gear is connected on intermediate gear shaft through a unilateral bearing, this driven I shelves gear be located at the active I shelves gears engaged on the motor shaft; Driven II shelves gear is connected on the intermediate gear shaft through spline fitted, and this driven II shelves gear is enclosed within the active II shelves gears engaged on the motor shaft with sky; Driving pinion and intermediate gear shaft are an integral body;
One driving shaft is connected in housing through the bearing location, drives gear wheel and is connected on the driving shaft through spline fitted, this driving gear wheel and the driving pinion engagement that is located on the intermediate gear shaft; One end of driving shaft stretches out housing and wheel is connected.
Two grades of automatically controlled variable speed electric motors, particularlies of described a kind of battery-operated motor cycle, its said magnet spool is connected with the DC power supply of 24V through lead and through the shift switch.
Two grades of automatically controlled variable speed electric motors, particularlies of described a kind of battery-operated motor cycle, its said active I shelves gear, active II shelves gear, driven I shelves gear, driven II shelves gear, driving pinion and driving gear wheel are spur gear, perhaps are helical gear.
The present invention selects the freewheel clutch of integrated one-way bearing as driven I shelves gear for use, and initiatively II shelves gear is selected the freewheel clutch of magnet control for use.
Under the situation of shift switch closure; The magneticaction that electromagnet produces is on the center cams of freewheel clutch and make it press to frictional disk when receiving frictional resistance; Ability transferring power or motion, initiatively II shelves gear and motor shaft rotate synchronously and drive driven II shelves gear and rotate; Because the rotating speed of driven II shelves gear is higher than driven I shelves gear; Driven I shelves gear is surmounted under the effect of integrated one-way bearing; Transferring power no longer; The motor power warp is delivered to the driving gear wheel with the driving pinion that driven II shelves gear rotates synchronously, is delivered to the drive shaft wheel again.
Break off magneticaction at the shift switch and eliminate, freewheel clutch is thrown off, and initiatively II shelves gear dallies on motor shaft; Both forward and reverse directions is not transferring power or motion; At this moment the speed of wheel slows down, and the integrated one-way bearing that is located on the driven I shelves gear is not surmounted, can transferring power; The motor power warp is delivered to the driving gear wheel with the driving pinion that driven I shelves gear rotates synchronously, is delivered to the drive shaft wheel again.
The present invention compares with prior art and has the following advantages: because motor and gear combination are one, not only structure is simple and clear, compact, good heat dissipation effect, and long service life, and processing and manufacturing easily, cost is lower; Change to II shelves speed from I shelves speed; Only need closed shift switch to get final product, change to I II shelves speed, only need to break off the shift switch and get final product from II shelves speed; And need not realize that variable speed operation is very easy, reliable through structure than the complicated mechanical toggle mechanism.
