Abstract

The invention relates to a damper device, in particular a torsional vibration damper (11) for a vehicle, preferably for a torque transmission device (10) or a torque converter of a vehicle, for transmitting a torque between a drive side (12) and an output side (14) of the damper device, said damper device comprising: an input element (16), the rotation of which is restricted, in relation to an intermediate element (22) located downstream of the input element (16) in a torque transmission path, by the action of a first energy storage element (18), thus forming a first damping stage (20); and comprising an output element (24) located downstream of the intermediate element (22) in the torque transmission path, the rotation of said output element being restricted, in relation to the intermediate element (22), by the action of a second energy storage element (26), thus forming a second damping stage (28). The damper device, or the first damping stage (20) and / or the second damping stage (28) is or are designed such that the first damping stage and / or the second damping stage are substantially mechanically bypassed by means of a blocking action.

Description

technical field [0001] The invention relates to a damper arrangement, preferably a torsional vibration damper, for a vehicle, in particular for a torque transmission device or a converter of a vehicle, for transmission between the drive side and the driven side of the damper arrangement torque. Furthermore, the invention relates to a torque transmission device or converter, in particular a hydrodynamic torque converter, for a vehicle, preferably for a drive train of a vehicle. Furthermore, the invention relates to a method for constructing a damper arrangement, in particular a torsional vibration damper. Background technique [0002] When the crankshaft rotates during vehicle operation, superimposed rotational imbalances occur at the crankshaft of the periodically operating internal combustion engine of the vehicle, wherein the type and / or frequency of the rotational imbalances change with the rotational speed of the crankshaft. During operation of the vehicle, relatively ...
