Automotive power train.

摘要

As a torque transmitting member, an annular resilient disc interconnects a crankshaft and an annular flywheel. The crankshaft has an axially extending cylindrical wall in opposed and spaced relationship to an inner peripheral wall of the annular flywheel. For reducing vibrations of annular resilient disc, an elastic annular body has an inner peripheral wall fixed to the crankshaft and an outer peripheral wall opposed to the inner peripheral wall of the flywheel. A heat insulating ring or heat insulating pieces are provided to reduce transmission heat from the flywheel to the elastic annular body. Alternatively, a heat insulating space or spaces maly be provided. <IMAGE>
