As the secondary reduction driven gear is mounted at the left part of the driving shaft through the overrunning clutch, the speed regulating mechanism and the motor are effectively protected; and the electric motorcycle can run continually so long as intermittent power supply is provided, so that not only can the electric energy be saved by 30-50 percent, but also the motor can be cooled down in time, and the service life is prolonged.
Description
Technical field
The utility model relates to the battery-operated motor cycle parts, is specifically related to a kind of battery-operated motor cycle two-stage gear automatic speed regulation motor.
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 the utility model provides a kind of battery-operated motor cycle two-stage gear automatic speed regulation motor, and its structure is concisely compact, easy to operate, safe and reliable, long service life, and energy-saving effect is obvious, and processing and manufacturing easily, and cost is lower.
The described a kind of battery-operated motor cycle two-stage gear automatic speed regulation motor of the utility model comprises housing, is located at motor and speed adjusting gear in the housing, it is characterized in that:
The stator of said motor is located on the inwall of housing, and motor shaft is connected in housing through bearing location, and the rotor of motor is located on the left part of motor shaft and is corresponding with motor stator;
Said speed adjusting gear comprises the first order deceleration driving gear that is located on the said motor shaft right part, be located at first order deceleration driven gear on the jack shaft right part, be located at the second level deceleration driving gear on the jack shaft left part and be located at the second level deceleration driven gear on the driving shaft left part through a freewheel clutch; First order deceleration driving gear and the engagement of first order deceleration driven gear, second level deceleration driving gear and the engagement of second level deceleration driven gear.
Described a kind of battery-operated motor cycle two-stage gear automatic speed regulation motor, its said motor shaft, jack shaft and driving shaft are parallel to each other, and all be connected with shell through bearing, and the right parts of driving shaft stretches out housing and wheel is connected.
Described a kind of battery-operated motor cycle two-stage gear automatic speed regulation motor, its said motor is a dc brushless motor, rated power 500-1500W, rotating speed are 4200-4500 rev/min.
Described a kind of battery-operated motor cycle two-stage gear automatic speed regulation motor, its said first order deceleration driving gear, first order deceleration driven gear, second level deceleration driving gear and second level deceleration driven gear are helical gear, perhaps are spur gear.With the helical gear is preferred plan, can reduce noise.
Described a kind of battery-operated motor cycle two-stage gear automatic speed regulation motor, its said first order deceleration driven gear, second level deceleration driving gear and jack shaft are for dividing body structure.Be convenient to make in batches processing, production efficiency is provided, reduce cost.
The utility model is compared with prior art and had the following advantages: because deceleration driven gear in the second level is installed on the driving shaft left part through freewheel clutch, when the speed of battery-operated motor cycle was elevated to certain value, deceleration driven gear in the second level was around driving shaft idle running; No longer transmit torque; At this moment, power cutoff, battery-operated motor cycle continues to go by inertia; The wheel that is rotated further can instead not drag speed adjusting gear and motor yet, thereby has effectively protected speed adjusting gear and motor; When the speed of battery-operated motor cycle dropped to certain value, deceleration driven gear in the second level combined with driving shaft, transmitted torque, and at this moment, the swing handle energized is quickened battery-operated motor cycle, makes battery-operated motor cycle continue to go.Because only needing interruptedly supplying power just can be that battery-operated motor cycle continues to go, not only can practice thrift the electric energy of 30-50%, and can also in time be cooled off by motor, prolong the useful life of motor.Owing to saved shift member, not only structure is simple and clear, compact, and processing and manufacturing easily, and cost is lower.
