Abstract
A torsion damping device, particularly for use with automotive vehicles and of the kind comprising a support structure (11) mounted on a wheel member, e.g. a flywheel (1). The flywheel is fixed to a first shaft (A) by first fastening devices (2), and a hub (12), secured to a second shaft (B) for rotation therewith. The hub is coupled with the support structure (11) through resilient springs (14). The support structure (11) constitutes one (22) of the components (22, 23) of a sealed casing (20), which is at least partially filled with a lubricant fluid and which is secured on the flywheel by second fastening devices (21) located radially outwardly of the first fastening devices (2). The casing (20) carries and encloses a torsion damper (15) having peripheral resilient springs (14A, 14B).
