Abstract
A lockup clutch at a hydrodynamic torque converter is constructed with a torsional vibration damper which has a drive-side transmission element and a driven-side transmission element which is rotatable relative to the latter. Both of the transmission elements are provided with driving devices for driving elastic elements of a damping device. A carrier for a compensation flywheel mass is associated with the driven-side transmission element, wherein the carrier is connected with the turbine wheel on the one hand and with the driven-side driving device of the elastic elements on the other hand so as to be fixed with respect to rotation relative thereto and is provided at least with a cutout for receiving the compensation flywheel mass. The cutout has a guide path at least in its area of contact with the compensation flywheel mass, which guide path allows a movement of the compensation flywheel mass with at least one component perpendicular to the radial direction at the carrier.
