Abstract

A two-mass flywheel has a first flywheel which can be connected to the crankshaft of an internal combustion engine, and can be provided with a thrust bearing for a hub of a second flywheel. The first flywheel can also be designed in its circumferential area with a radial bearing for the hub. The second flywheel can preferably rotate in synchronization with the first flywheel and can also preferably execute a limited rotation relative to the first flywheel. On this flywheel device, the thrust bearing is oriented so that on one hand, a sufficient supply of lubricant to the thrust bearing is always provided, and on the other hand, so that there is an optimal axial guidance of the hub. The invention teaches that this object can be achieved by a thrust bearing with displacement limit stops for the hub provided on both sides of the hub and extending to the radial bearing.
