Dual-mass flywheel disposed in the drive train of a motor vehicle.

摘要

Dual-mass flywheel disposed in the drive train of a motor vehicle, with a rotationally symmetrical primary part (12) which, with the crankshaft of an internal combustion engine, is connected to a secondary part (18), the indirectly or directly on a transmission shaft falls, and with a spring - and cushion unit (16, 26) to absorb the torsional vibrations emanating from the crankshaft, wherein the spring unit (26) is prestressed in such a way between the primary part (12) and the secondary part (18) is arranged, that they are below a defined engine torque of a rigid connection is produced and that, furthermore, the spring unit (26) is drivingly a second spring unit (30) is connected downstream, which substantially only below the defined engine torque is effective, characterized in that the second spring unit (30) between the first, with the primary part (12) cooperating secondary part (18) and a second secondary part (28) is switched on.
