The invention discloses an automatic gear shifting differential motor. A long driving shaft of a power motor is provided with a large driving gear and a small driving gear, and a left end of a middle shaft gear is provided with a high-speed gear. The left end of the middle shaft is provided with a low-speed gear. The large driving gear and the small driving gear are respectively engaged with the high-speed gear and the low-speed gear. A differential gear is disposed on an external circle of a differential, and the differential gear is engaged with the middle shaft gear. A flexible clutch is disposed between the high-speed gear and the low-speed gear, and the flexible clutch is provided with a synchronous claw. The high-speed gear and the low-speed gear are provided with synchronous circular holes. An intelligent controller is used to automatically control a soft driving motor to drive a screw rod, a driving plate, a sliding sleeve pipe, a shifting shaft, a shifting fork sleeve pipe, a shifting fork, a front pulley, a rear pulley, and the synchronous claw according to the changing of the rotating speed and the load of the power motor, and the synchronous claw slides into the synchronous circular hole of the low-speed gear or the synchronous hole of the high-speed gear under action of elastic pulling force of a front tension spring and a rear tension spring, and then a high-speed to low-speed gear shifting function is realized, and gear interfering, transmission delay, and impact in a gear shifting process are prevented. The automatic gear shifting differential motor requires less gears, and has advantages of simple structure, low costs, and high reliability.
Description
technical field [0001] The invention relates to a differential motor for an electric tricycle, to be precise, an automatic shifting differential motor. Background technique [0002] At present, with the change of market demand, the differential motor of the electric tricycle has gone through the process of continuous progress and development from the initial constant gear shifting to manual shifting, and from manual shifting to automatic shifting. There is an application number of The name "2015104435079" is an invention patent of "automatic shifting motor". It is an ideal shifting method that automatically shifts between high and low gears according to the change of motor speed and load, and solves the mechanism damage caused by improper manual shifting operation. , but it has the disadvantages of complex structure and high cost. Contents of the invention [0003] In order to overcome the deficiencies of the existing automatic shifting motors, the present invention intro...
