Abstract
The invention relates to a device for damping vibrations, for a motor vehicle transmission drivetrain, comprising: a first element and a second element (2) that are rotationally movable around a rotation axis X; elastic damping means 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 so that a curvilinear trajectory can be executed on at least a predetermined angular sector (A), the curvilinear movement of the rolling body with respect to the second element being accompanied by a movement of the rolling body on the elastic blade, causing the latter to flex.
Claims19
A device for damping (in particular, torsional) vibrations, for a motor vehicle transmission drivetrain, comprising:
- a first element (3) and a second element (2, 102) that are rotationally movable around a rotation axis X;
- and
- elastic damping means coupling the first element (3) and the second element (2, 102) so as to allow torque transmission with vibration damping between the first element (3) and the second element (2, 102), said torque transmission with damping being accompanied by a relative rotation between the first element (3) and the second element (2, 102);
- said elastic damping means having at least one elastic blade (13, 14, 113, 114) mounted rotationally integrally with the first element (3);
- the damping device furthermore comprising:
- a rolling body movable with respect to the second element so that a curvilinear trajectory can be executed on at least a predetermined angular sector (A), the curvilinear movement of the rolling body with respect to the second element being accompanied by a movement of the rolling body on the elastic blade, causing the latter to flex.
