Abstract
A power train includes: an engine including an engine case; a transmission including a transmission case that is fastened to the engine case; an electric motor provided inside the transmission case; and a heat insulator provided between the engine case and the transmission case, and being lower than thermal conductivity of the engine case and thermal conductivity of the transmission case.
Claims12
A power train comprising:
- an engine including an engine case;
- a transmission including a transmission case that is fastened to the engine case by a fastening bolt;
- an electric motor provided inside the transmission case;
- and
- a heat insulator provided between a mating surface of the engine case and a mating surface of the transmission case, and being lower than thermal conductivity of the engine case and thermal conductivity of the transmission case,
- wherein the fastening bolt passes through the heat insulator.
