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.

Abstract: An integration element including a shaft and a housing, wherein the housing includes a passage for the shaft and the shaft includes connecting elements on the shaft ends which are accessible from outside the housing, these elements providing a rotationally-fixed connection to connecting shafts. The housing has at least one connection for fastening to a connection structure and the shaft together with the housing delimits a measuring equipment space for receiving measuring equipment. The housing is formed by at least two housing parts detachably connected to each other, said housing parts being designed to be separated around the full extent of their circumference surrounding the shaft to allow access to the measuring equipment space. The housing has bearing seats for shaft bearings and these shaft bearings support the shaft in a rotatable manner with respect to the housing.

Abstract: A bearing ring, in particular of a rolling bearing or a sliding bearing, including a body made of a magnetostrictive material, having a first raceway (2) and a second, axially spaced apart, raceway (2?) and a permanent magnetization (3) which is impressed into the material of the body between the raceways (2, 2?) and which runs around an axis of rotation (9) of the body. According to the invention, the bearing ring achieves the object of improving the structural integration of a torque sensor into a bearing, which torque sensor generates a torque-dependent magnetic field by utilizing the inverse magnetostrictive effect.
