Abstract: A device for damping torsional oscillations, including: a pendulum-type torsional oscillation damper, a supplementary torsional oscillation damper including an input element, an output element, wherein both are configured to rotate around one axis rotation, and at least one mechanical energy accumulator device disposed between the input and output elements, a torque limiter, including at least one friction coating fixed on a disk, configured to be displaced around the axis. The disk is connected to rotate with the input element of the supplementary torsional oscillation damper and the friction coating is fixed to the disk of the torque limiter by an adhesively bonded surface-to-surface joint.

Abstract: A torque transmission device includes a first element, a second element, and a third element which are able to rotate about an axis of rotation; a first spring which is arranged between the first element and the third element; a second spring which is arranged between the second element and the third element; a first supporting seat positioned at a first end of the first spring; and a second supporting seat positioned at a first end of the second spring. The third element includes a torque transfer element directly transferring torque between the first spring and the second spring.

Abstract: A torsion damping device for a vehicle transmission line including a first rotating element, a second rotating element, a main damper, a third rotating element and an additional damper, so that: when the angular displacement between the first and second rotating elements is greater than zero and less than said first threshold, the at least one main spring is compressed while the third rotating element is rotated by the first rotating element via the uncompressed additional spring; and when the angular displacement between the first and second rotating elements is greater than said first threshold, the at least one main spring is compressed and the at least one additional spring is compressed in parallel, the compression of the additional spring being accompanied by the relative rotation of the first rotating element and the third rotating element.

Abstract: A torsion damping device for a vehicle drivetrain including a first rotary element, a second rotary element, an elastic device, a friction device comprising an actuating washer mounted to rotate as one with a friction washer and comprising an actuating tab interposed circumferentially between a first end of a spring and the first rotary element so as to allow relative rotation between the actuating washer and the second rotary element when the first end of the spring is compressed by the first rotary element in the direction of a second end of the spring opposite to the first end.
