ABSTRACT:
A torsion damper is of the kind in which the springs bear against thrust inserts or spring seats. The anterior part of each spring seat has a circular perimeter, the diameter of which is smaller than the internal diameter of the outermost spring of the associated group of springs, while the posterior part of the spring seat includes a barrel element which projects from the back of the anterior part of the spring seat. This barrel element also extends radially beyond the perimeter of the anterior part, at each end of the barrel element, so that the outermost spring of the associated group bears on the projecting portions of the barrel element in end thrust engagement.
