Abstract
A damping device for damping vibrations of a motor vehicle transmission drivetrain. The damping device features a first element and a second element (2) rotationally movable around a rotation axis X, an elastic damping member having an elastic blade (13, 14) mounted rotationally integrally with the first element (3) and a rolling body movable with respect to the second element along a curvilinear trajectory over at least a predetermined angular sector (A). Movement of the rolling body along the curvilinear trajectory with respect to the second element is accompanied by a movement of the rolling body on the elastic blade, causing the elastic blade to flex.
