Apparatus for transmitting power from a power generating device having high torque irregularities to an electrical machine, and motor vehicle comprising such apparatus

Abstract

An apparatus for transmitting power from a power generating device to an electrical machine suitable to be installed onboard a motor vehicle is disclosed. The apparatus comprises a power take-off (PTO) device which comprises a gear wheel which is suitable to receive rotary power from the power generating device. The apparatus further comprises a power transmission which is suitable to receive rotary power from the gear wheel and to transfer at least part of the received rotary power to the electrical machine. The apparatus further comprises a decoupler that is interconnected between and transfers rotary power from the gear wheel in input to the power transmission, wherein the decoupler is at least partially fitted inside the gear wheel and reduces the torque amplitude transmitted in input to the power transmission relative to the torque amplitude received in input by the gear wheel from the power generating device.
