Abstract
A torsion damping device comprises two coaxial parts, one of which consists of a damper plate and a hub coaxial with the damper plate, the hub and damper plate having cooperating teeth defining a circumferential clearance between them so that the hub and damper plate are able to undergo a limited relative angular displacement which is defined by a circumferential clearance between the two sets of teeth. A ring extends parallel to the damper plate and has a further set of teeth, of resilient material, complementary to the hub teeth and meshing with the latter so as to define a further circumferential clearance between the resilient teeth and the hub teeth. This further circumferential clearance is smaller than that between the two sets of teeth of the damper plate and the hub themselves. In addition, the set of teeth on the hub is extended axially so that it can mesh with the teeth on both the damper plate and the ring.
