A bearing assembly includes an inner bearing ring, an outer bearing ring and rolling bodies located between the inner bearing ring and the outer bearing ring. A gap is defined by a radially outer surface of the inner bearing ring and a radially inner surface of the outer bearing ring. The radially inner surface of the outer bearing ring includes a first radial surface portion that is offset a greater distance from a center of the bearing than a second radial surface portion. The first and second radial surface portions are connected by a sloped surface. A sealing arrangement located in the gap. The sealing arrangement includes a first annular body including an elastomeric sealing protrusion to contact the sloped surface of the outer bearing ring.

The present invention relates to an arrangement for measuring a force and/or a torque on a machine element extending in an axis, using the inverse magnetostrictive effect. The machine element has at least one permanent magnetization. The permanent magnetization extends along a closed magnetization path. The magnetization path runs preferably at least partially along the surface of the machine element. The arrangement further includes at least one magnetic field sensor which is arranged opposite the machine element. The magnetic field sensor serves to determine a magnetic field and is designed to measure at least one vector component of a magnetic field coming from the machine element, which field is produced on the one hand by the permanent magnetization and on the other hand by the force and/or by the torque. According to the invention, the orientation of the permanent magnetization relative to the axis changes along the magnetization path.

A mounting device for mounting a driven and/or a drivable wheel of a vehicle. The mounting device makes it possible to measure a drive torque or a drag torque that acts between a wheel and a driveshaft. The torque is transmitted from the driveshaft to the wheel by radial teeth on a bearing inner ring where there is a pressure-sensitive measuring element to measure axial forces as a characteristic of the particular effective torque. In addition, a device to control the distribution of the drive and drag torques acting on the driveable wheels of a vehicle is disclosed. To measure the drive and drag torque distribution, there is a sensor unit on each drivable wheel to measure the torque acting on each wheel.
