Differential gear motor for dividing driving power to power trains of motor vehicle, has coaxial shaft motor comprising inner and outer rotors whose rotational movements are transferred to drive shafts of power trains, respectively

摘要

The gear motor has a coaxial shaft motor (A) comprising an inner rotor whose rotating movement is transferred to a drive shaft (8) of power trains through an inner engine shaft (1) and bevel gears (4, 5) of the drive shaft. Rotating movement of an outer rotor of the shaft motor is transferred to another drive shaft (7) of the power trains through an outer motor shaft (2) i.e. sleeve shaft, and bevel gears (3, 6) of the latter drive shaft. The drive shafts are coupled against each other and formed as a coaxial shaft assembly. The rotors are freely and rotatably supported in a housing (D).
