Abstract

A friction clutch for a motor vehicle is embodied with a centrifugal mass device, which has at least one mass-bearing compensating system. At least one component of the centrifugal mass device is equipped, to form the compensating system, with at least one chamber that holds, to a predetermined degree of fullness, a fluid medium, whose position in the chamber changes when a torsional vibration occurs. The effect resulting from this position change depends on the density and viscosity of the medium, on the one hand, and, on the other hand, on the arrangement of the chamber, which determines the vibrational behavior of the medium, the shape of the chamber, which determines the movement resistance, and its degree of fullness.
