ABSTRACT:
A torsion damping device includes a support wheel, having first fastening screws for attaching it to a driving shaft, a damper plate, and peripheral springs acting between the support plate and the damper plate. The damper plate, carrying a pair of guide rings, constitutes, together with the springs and a drive plate, a torsion damper which is contained in a sealed housing, the components of which are secured together by second fastening screws.
The inner periphery of the sealed housing has a diameter greater than that of the pitch circle on which the holes for the first fastening screws are arranged in the support wheel, while the damper plate emerges radially from the housing, in a manner which provides axial location but circumferential sliding movement of the damper plate in the housing while preserving sealing. The second fastening screws of the housing are separate from the first fastening screws and their holes in the support wheel, while one of the components defining the housing carries a cover for urging the torsion damper into rotation, the latter being conformed so as to cooperate therewith.
