Abstract
A device for driving a piece of equipment from a driving shaft has a torsional vibration damper and comprises a primary element for connection to the driving shaft and a secondary element for connection to the piece of equipment. A first elastic member surrounds the primary element and an inertia ring surrounds the first elastic member. The secondary element has a rim extending parallel to the longitudinal axis of the device, and the rim partly covers the inertia ring. A cylindrical ring is located between the rim and the inertia ring for providing friction and a radial guide bearing. The secondary element has a transverse covering integral with the rim extending radially inwardly toward the longitudinal axis of the driving shaft. A second elastic member is located between the transverse covering and the primary element.
