Abstract

A roller device for a traction mechanism drive of a motor vehicle, with a roller element for introducing a torque provided via the traction mechanism and a driven shaft for driving an auxiliary unit. The roller device has a magnetic coupling for non-positive torque transfer between the roller element and the driven shaft. The magnetic coupling has a primary-side unit connected to the roller element with a primary magnetic element and a secondary-side unit connected to the driven shaft with a secondary-side magnetic element. The magnetic elements are permanent and/or electromagnetic elements. The non-positive torque transfer is realized by magnetic fields of the primary-side and secondary-side magnetic elements. At least one magnetic element of the two units for changing the magnetic field overlap of the magnetic fields of the primary-side and secondary-side magnetic elements is movably arranged within its unit. A corresponding traction mechanism drive and method are provided.
