ABSTRACT:
An integrated pulley-torsional damper assembly (1) comprises a hub (2) designed for being rigidly connected to a drive member (3), a pulley (4) connected to the hub (2) by means of a first ring (5) made of elastomeric material having the function of filter for the torsional oscillations, and an inertia ring (6), connected to the hub (2) by means of a second ring (7) made of elastomeric material, which defines with the inertia ring (6) a damping system. The first elastomeric ring is connected to the hub by mans of a coupling flange (25), which can be pack-tightened between an internal annular flange (10) of the hub and the drive member (3), the hub (2) comprising a first cylindrical wall (11) and a second cylindrical wall (12), which are coaxial with respect to one another and define between them an annular cavity (9) housing the first elastomeric ring (5), the external cylindrical wall (12) defining a support for the second elastomeric ring (7).
