Abstract (en)
[origin: WO2009033638A1] The present invention relates to a dual-mass flywheel for a drive train of a motor vehicle, having one primary flywheel mass and one secondary flywheel mass (13), which are coupled to one another in a rotationally elastic manner via at least one spring device (19, 39, 53). At least one gear device (21, 31, 51, 51' ') is disposed between the spring device and at least one of the two flywheel masses, said gear device causing a deflection movement of the spring device relative (19, 39, 53) to a rotational movement of the two flywheel masses in relation to one another, wherein a characteristic curve of the spring device may be modified by the gear device (21, 31, 51, 51' ').
