Embodiment Construction

[0027] exist figure 1 and figure 2 A torsional vibration damper 1 is described, which has an axially displaceable coupling part 3 and a rotational axis 6 arranged in a housing 2 . The housing 2 forms the first element 4 and has a first housing cover 4.3. The axis of rotation 6 forms the second element 5 and passes through the second housing cover 5.3. The housing 2 (first element 4 ) and the rotation shaft 6 (second element 5 ) are rotatable relative to each other. The housing 2 (first element 4 ) is thus connected to the coupling part 3 via a rotatably mounted rigid first coupling element 4 . Element 5.1 is connected to coupling part 3. The first coupling element 4.1 is designed in the form of a ball stud and is supported with its spherical end on the one hand in a first receptacle 4.2 of the first element 4 (on the housing 2 ) so as to be rotatably movable and on the other hand It is supported for rotational movement in the receptacle 3 . 1 of the coupling part 3 . Si...

Abstract

A torsional vibration damper (1) comprising two elements (4, 5) which are rotatable relative to one another making use of at least one coupling part (3) which is arranged axially displaceable in a housing (2), in which the housing (2) is divided by the coupling element (3) into a first pressure chamber / partial chamber (D1) and a second pressure chamber / partial chamber (D2), and the first pressurechamber (D1) is connected to a first damping chamber (12) and the second pressure chamber (D2) is connected to a second damping chamber (13) and the first pressure chamber (D1) is filled with a damping medium (10) and the first damping chamber (12) is filled with the damping medium (10) and / or a first damping element (14) and the second pressure chamber (D2) is filled with a damping medium (10) and the second damping chamber (13) is filled with the damping medium (10) and / or a second damping element (15).

Description

technical field [0001] The present invention relates to a torsional vibration damper installed between a drive system and a driven system and used to attenuate input and output vibrations and balance torque fluctuations. Background technique [0002] Various torsional vibration dampers are known in which the active element is connected to the driven element via torsion springs for torque transmission (eg DE 2005037996 B3). [0003] Systems are also known in which torsional vibrations are attenuated by means of spring elements which can be acted upon radially or in the circumferential direction (DE 19812303A1, DE 19733334A1). [0004] A torsional vibration damper with laterally displaceable damping elements is known from DE 3228673 A1. A torsional vibration damper, in particular for a clutch disk of a friction clutch for a vehicle, has two damping parts rotatable relative to one another about a common axis of rotation, which are coupled to one another via an axial thrust sur...
