Abstract
A torsional damper for vehicle transmission systems comprises an input element rotationally movable around an axis and exhibiting at least one window comprising two angularly spaced lateral edges and a radially external edge. An output element is rotationally movable around the axis and exhibits at least one window comprising two angularly spaced lateral edges and a radially external edge. An elastic return member capable of being received simultaneously in the window of the input element and the window of the output element generates a force acting against rotation of the output element with respect to the input element. An additional element is rotationally movable around the axis and integral with one of the input element and output element. The additional element exhibits an edge comprising at least one region projecting radially into the window of the input element and output element with which the additional element is integral.
