Description
Technical field
The present invention relates to driving device for electric vehicle field, more particularly to a kind of electronic automotive self-adapting to increase square energy-conservation and drive automatically
Dynamic assembly.
Background technology
At present, automobile, motorcycle, electric bicycle are essentially all directly to control section by speed adjusting lever or accelerator pedal
Valve or current control speed, or speed change is realized using hand-control mechanical automatic automatic transmission mode.The behaviour of handle or accelerator pedal
The operation of human pilot is depended entirely on, operation and garage's situation mismatch can be usually caused, cause motor operation unstable,
There is stall phenomenon.Motor vehicle is in the change, in the case where being unaware of running resistance, controlled by rider according only to experiential operating
Speed variator, problems with unavoidably be present：1st, motor speed is forced due to running resistance increase in startup, upward slope and heavy load
Decline and worked in inefficient area.2nd, because no mechanical transmission adjusts moment of torsion and speed, can only be promoted the use of in plains region,
It can not meet to use under mountain area, hills and heavy load conditions, reduce use range.3rd, installing space is small at driving wheel, installation
It is difficult to accommodate automatic transmission and other new technologies again after engine or motor.4th, do not possess adaptive function, it is impossible to from
Dynamic detection, amendment and the operating mistake for excluding driver.5th, when speed change is unexpected, power of motor is necessarily caused to be hindered with traveling
Power is difficult to match.6th, continue apart from it is short, climbing capacity is poor, accommodation is small.
Spirally bored as Chinese Patent Application No. 201510565642.0 discloses a kind of battery-operated motor cycle inner rotor motor
Set transmission self-adapting automatic gear shift drive assembly, it include internal rotor motor, casing, power transmission shaft, slowly keep off transmission mechanism and
