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.
