The invention relates to vehicle engineering and to other mechanisms which require the change of speed of the output shaft of an electric motor. According to the invention, the transmission ratio converter is designed in the form of a planetary differential, one central wheel of which is connected to the output shaft, the second central wheel is connected to the rotor of the electric motor, which is inductively coupled to a stator, and a carrier, on which a pair of satellite gears running on the central wheels is mounted, is connected to an additional rotor which is also inductively coupled to the stator and, when rotating, operates as a generator for producing electric energy returning it to a network and a force breaking the rotor redistributes a torque in the arms of the differential, thereby making it possible to change the speed of the output shaft. |
