A device (1) for damping torsional vibrations of a drive source, comprising – an input element (2), – an output element (3) which is arranged coaxially with respect to the input element (2), – a first ball ramp mechanism (4) which has a first, outer ball ramp disk (6) and a first, inner ball ramp disk (7), wherein the first, outer ball ramp disk (6) is arranged substantially rotationally conjointly and axially non-displaceably on the input element (2), and the first, inner ball ramp disk (7) is arranged rotatably and axially displaceably on the input element (2) or on a component connected to the input element (2), – a second ball ramp mechanism (5) which has a second, outer ball ramp disk (8) and a second, inner ball ramp disk (9), wherein the second, outer ball ramp disk (8) is arranged substantially rotationally conjointly and axially non-displaceably on the input element (2) and the second, inner ball ramp disk (9) is arranged rotatably and axially displaceably on the input element (2) or on a component connected to the input element (2), – at least one elastic element (10), wherein the elastic element (10) is arranged along its loading direction between the first, inner ball ramp disk (7) and the second, inner ball ramp disk (9) and the elastic element (10) is operatively connected, in the region of its ends, to the respective inner ball ramp disk (7, 9), wherein the device (1) comprises a pick-off ring (11), the inner contour (12) of which is designed such that at least one receptacle (13) is formed which substantially corresponds to a section of the outer contour of an elastic element (14), wherein the receptacle (13) surrounds the elastic element (10) at least in sections, and the pick-off ring (11) is connected rotationally conjointly and axially immovably to the output element (3) or to a component connected to the output element (3). |
