Abstract
A two part flywheel having a torsional vibration damper with a plurality of inertial masses, for installation in the drive train of a motor vehicle. The torsional vibration damper has three inertial mass systems. A first and a second inertial mass system are oriented so that they can rotate jointly and also relative to one another around a common first axis of rotation. The first inertial mass system and the second inertial mass system are connected rotationally elastically to one another by means of a spring system. A third inertial mass system which is movable relative to the first and the second inertial mass systems is rotationally connected by a transmission system to the first and/or second inertial mass systems. One of the inertial mass systems, in particular the first inertial mass system, is designed to be connected to the crankshaft of an internal combustion engine. The inertial mass of the third inertial mass system is defined essentially exclusively by the inertial masses of a plurality of inertial mass bodies which rotate around the first axis of rotation. Each inertial mass body can rotate or pivot around a second axis of rotation which is axially parallel to and offset from the first axis of rotation, and each inertial mass body is driven or pivoted around its second axis of rotation by the transmission system as a function of the relative rotational movement between the first and second inertial mass systems.
