  • Patent number: 11796005
    Abstract: Bearing arrangement for a machine element having a bearing having an outer bearing race radially fixed by a cylindrical cutout in the mounted state of the bearing arrangement; a locking element having an annular radial portion and at least one axial portion; and the annular radial portion of the locking element cooperates with a region of the outer bearing race on a first axial side of the outer bearing race to secure the outer bearing race at the first axial side; and at least one securing element which, in a mounted state of the bearing arrangement, is in operative engagement with the at least one axial portion of the locking element and with the machine element such that the locking element secures the outer bearing race at the first axial side.
    Type: Grant

  • Publication number: 20230184298
    Abstract: The invention relates to a torque transmission device (1) for the drive train of a motor vehicle, comprising an input element (2) and a cover element (16) which is connected to the input element (2) for conjoint rotation, and comprising an output element (3), wherein: the output element (3) and the input element (2) are rotatable in relation to one another via an energy accumulator device (4) and about a common axis of rotation A; a torque-limiting device (10) is located between the input element (2) and the output element (3); the torque-limiting device (10) is designed to transmit a torque between the input element (2) and the output element (3) up to a limit torque value and, when the limit torque value is exceeded, to transmit a torque at least in part or to transmit no torque at all; the torque-limiting device (10) is connected to the energy accumulator device (4) via a frictional and/or form-fitting connection (8), is connected to the input element (2) via a first frictional connection (9), and is conne
