Publication number: 20130272636Abstract: The present invention relates to a rolling bearing for rotatively mounting a machine element, including a sensor for measuring a mechanical load acting on the rolling bearing. The rolling bearing can be a wheel bearing of a motor vehicle, for example, or the bearing of a gearbox shaft. The rolling bearing includes a first bearing ring and a second bearing ring, which can be rotated with respect to the first bearing ring. A bearing inner space, which has at least one first axial section in which rotatable rolling elements are arranged, is formed between the first bearing ring and the second bearing ring. The rolling bearing further includes at least one sensor for measuring a mechanical load acting on the rolling bearing, in particular for measuring a force or torque, or a physical variable derived from a force or torque, for example, angular momentum or mechanical tension.Type: ApplicationFiled: May 26, 2011Publication date: October 17, 2013Inventors: Jens Heim, Robert Heuberger

Mounting device with integrated torque measurement and device for the control of torque distribution
Patent number: 8560196Abstract: 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.Type: GrantFiled: June 5, 2007Date of Patent: October 15, 2013Assignee: Schaeffler Technologies AG & Co.
