ABSTRACT:
A torsion attenuator for boat transmissions including a primary part coupled with the flywheel of a motor, a secondary part coupled with the input shaft of a reversing gear, which secondary part can be rotated relative to the primary part, plural elastic elements acting in a direction opposite the direction of the relative rotation and arranged symmetrically with respect to the axis of rotation between the primary part and the secondary part. At least one friction element is also provided for inhibiting the relative rotation and arranged between the primary part and the secondary part. In order to make possible a large relative rotation between the primary and secondary parts and with the elastic elements being of a specific given length, it is provided that the elastic elements on the primary part and/or on the secondary part and the structure associated therewith are supported on a sloped plane active in peripheral direction.
