摘要:
The invention is a torque-limited coupling element including an input and output rotatably mounted about a common rotational axis, at least one Connection which is transferred from a first position into a second position upon exceeding a settable limit torque acting between the input and the output wherein in the first position the at least one connection connects the input and the output in a rotationally fixed manner, and in the second position, the input and the output are rotatably mounted relative to one another. A displacement body is movably mounted within a chamber filled with a magnetorheological fluid with the position of the displacement body resulting from a holding force provided by the magnetorheological fluid being under influence of a magnetic field.
