Patent number: 11313408Abstract: A bearing device for motor vehicle shafts is described, in particular for motor vehicle steering shafts. The bearing device is provided for torque transmission between an inner shaft and the hollow shaft surrounded by the inner shaft. The inner shaft and the hollow shaft each have opposing bearing grooves, in which rolling elements are received. At least one positive locking cam in radial direction is provided. A safety contour is assigned to the positive locking cam, the safety contour comprising two engagement positions for the positive locking cam. In the case of unoccupied bearing grooves the positive locking cam is rotationally movable along the safety contour between the engagement points during a torque transmission, in a manner that a defined relative movement between the inner shaft and the hollow shaft is possible, which generates both tactile feedback and acoustic feedback. Furthermore, an automotive shaft assembly is described.Type: GrantFiled: August 20, 2019Date of Patent: April 26, 2022Assignee: ZF Automotive Germany GmbHInventors: Thomas Hagen, Lars Ehrmann, Maria Hildebrand, Atanasio Oliveira
