Abstract: A roller riveting assembled hub bearing unit, the inner ring (2) of which has a radially elevated region for resolving production problems during the roller riveting process. For such a hub bearing unit, an optimal sensor arrangement, such as that required for rotational speed detection for example, is to be provided without having to accept disadvantages with rotational speed detection, sealing and strength optimization of the inner ring (2). A signal emitter (5) is arranged axially flush in a flat manner on the side of the vehicle on a higher area of the inner ring (2). A cover (8) axially covers the wheel hub (18) on the vehicle side. The detection of the movement of the signal emitter (5) takes place in the axial direction through the cover (8). To accommodate the sensor, the cover (8) comprises a protrusion (15) which is axially opposite the signal emitter (5), which can be arranged radially within the outer ring (3) either partially or completely.

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.
