Embodiment approach

[0029] Through coupling elements 5.1, 5.2 and springs 6, 7 ( figure 1 ) or buffer medium 10 ( figure 2 ) elasticity, the torsional vibration is damped between the first element 4 and the second element 5, and the torque peak is reduced. According to an embodiment not shown, for example, the housing as the first or second element can also be designed rotatably, and for example a stub shaft can be fastened to the housing. The housing is of course not mounted fixedly relative to the base in this case.

[0030] exist image 3 and 4 A variant of the damping element 1 is shown in , in which the first element 4 is formed in the form of a first axis of rotation and the second element 5 , which is rotatable relative to the first element, is the housing 2 .

[0031] according to image 3The respective third coupling element 4.3 is fastened pivotably on the receptacle 4.2 of the first element 4 and on the receptacle 5.2 of the second element 5. These third elements 4 . During rel...

Abstract

The invention relates to a torsional vibration damper (1) having a damping element disposed between a first element (4) and a second element (5), wherein the first element and the second element can rotate relative to each other. Said damper has or does not have a coupling part (3) that is located in a housing (2) and is axially displaceable along an axis (A) between the first and the second element, wherein: a) the coupling part displaces along the axis (A) against the spring force of at least one spring element (6, 7) and / or b) the coupling part displaces along the axis (A) against a medium acting on both sides of the coupling part, wherein the medium is located in internally or externally location partial spaces. Or that: in a design of the damping element having or not having the coupling part, c) compliant elements are integrated in third coupling elements and the coupling elements are connected to the first and the second element.

Description

technical field [0001] The present invention relates to a torsional vibration damper / torsional vibration damper installed between a driving system and a driven system and used for damping input and output vibrations and compensating torque fluctuations. Background technique [0002] Numerous torsional vibration dampers are known in which a drive element and a driven element are connected via a torsion spring for torque transmission (eg DE 10 2005 037 996 B3). Furthermore, systems are known in which torsional vibrations are damped by radial or circumferentially actable spring elements (DE 198 12 303 A1, DE 197 33 334 A1). [0003] A torsional vibration damper with a laterally displaceable damping element is known from DE 32 28 673 A1. This torsional vibration damper, which is especially suitable for the clutch disk of a friction clutch of a motor vehicle, has two damper parts that can rotate relative to each other about a common axis of rotation, the two damper parts being d...
