摘要： The invention relates to a device for transmitting or decoupling mechanical vibrations, comprising a first component and a second component, which are connected to each other by means of a coupling element that has a variably adjustable stiffness in at least one direction of action in which at least one component is supported in a vibrating manner. The invention is characterized in that the coupling element is a planar element having a planar-element top side and a planar-element bottom side and a planar-element longitudinal extent, the planar element being dimensionally stable in the planar-element longitudinal extent and elastic lateral to the planar-element longitudinal extent, that n
> 2 contacting agents are attached to the first component in a spatially fixed manner, by means of which contacting agents the first component contacts n
> 2 first contact points at the planar-element bottom side and/or planar-element top side of the planar element, that n
> 2 contacting agents are attached to the second component in a spatially fixed manner, by means of which contacting agents the second component contacts n
> 2 second contact points at the planar-element bottom side and/or planar-element top side of the planar element, and that both components are arranged such as to be rotatable relative to each other about a spatial axis oriented orthogonally to the planar-element longitudinal extent, said spatial axis coinciding with the at least one direction of action in which at least one component is supported in a vibrating manner.

摘要： A torque-limited coupling element is described, comprising an input part and an output part, each mounted rotatably about a common rotational axis, and at least one connecting means. If a predeterminable limit torque acting between the input part and output part is exceeded, the connecting means can be transferred from a first position, in which the connecting means non-rotatably connects the input part and output part to one another forming a positive engagement, into a second position, in which the input part and output part are mounted rotatably relative to one another. Furthermore, a method for torque-limited coupling and uses for such a coupling element are described. The invention is characterized in that the at least one connecting means is, in the first position, non-positively operatively connected, indirectly or directly, to a displacement body movably mounted inside a chamber filled with a magnetorheological fluid, with the position of the displacement body inside the chamber being supported by a displacement force caused by the magnetorheological fluid, a unit generating a magnetic field is provided on or in the region of the chamber and can be used to influence the displacement force of the magnetorheological fluid, and, if the limit torque is exceeded, the displacement body can be deflected inside the chamber against the displacement force caused by the magnetorheological fluid.
