ABSTRACT:
Apparatus for damping vibrations between at least two flywheels in the power train of a motor vehicle wherein one flywheel rotates with the output shaft of the engine and another flywheel can drive the input shaft of a transmission in response to engagement of a friction clutch. The flywheels are rotatable relative to each other against the opposition of one or more dampers which are installed in an annular chamber of the one flywheel. The chamber contains a supply of viscous damping fluid and the one flywheel has two disc-shaped sections which are made of sheet metal and define the chamber. The sections are welded to each other radially outwardly of the chamber.
