Abstract

A flywheel of an internal combustion engine, wherein the flywheel has a reduced outside diameter. The flywheel has lugs which point radially inward, which lugs facilitate the fastening of the flywheel to the clutch housing. It is thereby possible to locate the threaded fasteners on a smaller average diameter of the flywheel. The clutch disc has a maximum and a minimum outside diameter, to guarantee that it can be installed past the lugs. In particular when this type of flywheel is installed in a flywheel with two centrifugal masses, it is possible to use the radially outward space saved for an additional centrifugal mass of the primary centrifugal mass.
