A clutch, comprising
- a first clutch half;
- a second clutch half;
- a wear-afflicted damping element arranged between the first and second clutch halves;
- a first magnet arranged on the first clutch half;
- and
- a second magnet arranged on the second clutch half,
- wherein the first and second magnets interact to enable a contactless detection of a state of wear of the clutch.
A system, comprising:
- a clutch including a first clutch half, a second clutch half, a wear-afflicted damping element arranged between the first and second clutch halves, and first and second magnets arranged on the first and second clutch halves, respectively, for contactless detection of a state of wear of the clutch, said first and second magnets forming a combined magnetic field;
- and
- a sensor apparatus including a sensor configured to detect a physical variable of the magnetic field.
A method for ascertaining a state of wear of a clutch having a first clutch half with a first magnet and a second clutch half with a second magnet, and a wear-afflicted damping element arranged between the first clutch half and second clutch half, with the first and second magnets forming a combined magnetic field, said method comprising:
- initiating an intended operation of the clutch;
- detecting a physical variable of the combined magnetic field by a sensor apparatus;
- ascertaining a deviation between the combined magnetic field and a reference magnetic field based on the physical variable;
- ascertaining a state of wear of the wear-afflicted damping element of the clutch as a function of the deviation between the combined magnetic field and the reference magnetic field, wherein the deviation of the combined magnetic field corresponds to a wear-induced twist angle between the first and second clutch halves.
