Shaft output clutch type double-acting-force self-adaptive variable-speed electric driving system

The invention discloses a shaft output clutch type double-acting-force self-adaptive variable-speed electric driving system, which has the advantage of self-adaptive mechanical speed change, realizes switching and maintenance of a low-speed gear and a high-speed gear under the combined action of traction force and running resistance, can provide higher driving torque in a constant torque area, can also provide higher rotating speed in a constant power area, and has the advantages of high speed change speed, high speed change speed and the like. And low-speed, large-torque and high-efficiency requirements of various complex working conditions of vehicle acceleration, climbing and high-speed driving can be met. More preferably, the optimal working opportunity for optimizing the power of the motor can be selected, the power output efficiency of the driving motor is improved, the economical efficiency is greatly improved, the continuous acceleration performance is enhanced, a simple power transmission route is pr
