Abstract

A drive train of a motor vehicle includes a gear arrangement with at least two gear elements moveable relative to one another acts in a torque transmission path between an internal combustion engine and a transmission. The gear arrangement being connected between a drive-side flywheel mass and a gear-side flywheel mass. The gear arrangement includes at least one additional mass having a center of gravity (S.sub.p) which is displaceable radially in relation to an axis of rotation (D) of the torque transmission path as a function of a relative position of the at least two gear elements. In the event of a change in the relative rotary angle between the flywheel masses, a moment of inertia of the torque transmission path also changes, so that there is no definite resonant point and the torque transmission path takes effect as a self-steadying system. Furthermore, the additional mass may be arranged to generate a centrifugally dependent return force directed toward a specific relative rotary angle position. The force acts between two rotary parts rotatable at least to a restricted extent relative to one another and located in the torque transmission path. The specific relative rotary angle position lies between two relative rotary angle boundary positions delimiting a relative rotary angle range of the rotary parts. The gear arrangement may be arranged in a two-mass flywheel or a hydrodynamic clutch device in the motor vehicle drive train.
