摘要

A divided flywheel comprises a first flywheel mass (2) fixable on an internal combustion engine and a second flywheel mass which can be engaged with or disengaged from a gearbox by a clutch. The flywheel masses are journalled relative to each other by way of a bearing (4). The masses have a damping device between them, housed in a torus (9) which lies around the outer periphery of the flywheel. The second flywheel mass lies partly within the envelope defined by the torus (9) and the torus itself lies outside the friction damdiameter of the clutch. The damping device comprises helical compression springs (9) within the grease-filled torus (9). A wall (17) of the torus is adjoined by a membrane seal (18).
