Abstract

The invention relates to a multi-shifting and variable speed control system for an electrical motorcycle, and the system comprises a driving part, a shifting part and a controlling part; the driving part comprises a main transmission shaft of a driving motor, a plurality of active shifting gears and a reduction gear which are sequentially arranged on the main transmission shaft, a driven shaft, and a plurality of driven shifting gears which are sequentially arranged on the driven shaft and respectively correspond to / are engaged with the active shifting gears. The system is characterized in that the shifting part comprises a step motor, a variable speed drum, and a first shifting fork and a second shifting fork which are arranged on the variable speed drum, the first shifting fork matches with one active shifting gear on the main transmission shaft, and the second shifting fork matches with one driven shifting gear on the driven shaft; and the driving motor and the step motor are connected with the controlling part and a vehicle power supply by wire. The system has the advantages of enlarging the speed regulating range of the electrical motorcycle, thus improving the dynamic performance of the electrical motorcycle and saving electric energy.

Description

technical field [0001] The invention relates to an electric vehicle control system, in particular to an electric motorcycle gear shift control system. Background technique [0002] Most of the speed regulation methods of the existing electric motorcycles add a governor between the battery and the motor, and change the voltage pulse width to adjust the voltage to achieve the purpose of speed regulation. This method of adjusting the speed by adjusting the voltage will cause the battery current and voltage drop to be too large when the electric motorcycle starts or climbs, which will affect the release of energy stored in the battery and damage the battery. Its control method is to change the relative position of the magnetic steel and the Hall device by turning the handle to change the output voltage to adjust the speed. Its stability is greatly affected by the magnetic field strength of the magnetic steel, the ambient temperature, and the use time, which makes the speed cont...
