Clutch, has intermediate wheel arranged between guidance device and housing for transferring torque, and mechanism for producing and/or varying magnetic fields changing viscosity of magnetorheological liquid

摘要

The clutch (1) has an intermediate wheel (4) i.e. intermediate disk, arranged between a guidance device (2) and a housing (3) for transferring a torque. The wheel is connected with a shaft in a force-fit and/or form-fit manner, on the housing, where the wheel is adjusted to a form closure with the housing. A magnetorheological liquid (MRF) changeable in its viscosity is provided in a gap (18) between the wheel and the housing for transferring the torque. A mechanism is provided for producing and/or varying magnetic fields changing the viscosity of the MRF. An independent claim is also included for a method for switching a clutch.
