  • Device for actuating a parking lock means of an automatic transmission and method for operating such a device
    Patent number: 11746902
    Abstract: A device (1) for actuating a parking lock device (2) of an automatic transmission includes a piston (3) guided in a cylinder (5) and hydraulically displaceable counter to a spring force of an actuation spring (4). The piston (3) is form-lockingly fixable in a first position and in a second position by radially displaceable blocking elements (26) of a blocking device (15). The blocking elements (26) are radially displaceable by an actuation element (17). The radial displacement path of the blocking elements (26) and an operating condition of the actuation element (17) corresponding thereto in the first position of the piston (3) deviate from the radial displacement path of the blocking elements (26) and the operating condition of the actuation element (17) corresponding thereto in the second position of the piston (3).

  • Device for optimizing the feed function of the ring gear of a differential with regard to the maximum flow rate
    Patent number: 8152675
    Abstract: A device for optimizing the oil delivery function of the ring gear of a differential to maximize the volume of oil flow. The device includes an annular disk (6) which, when viewed in an axially direction, is arranged adjacent the ring gear (1) on the side of the ring gear (1) facing the differential cage (5) and is coaxial with the ring gear (1). The annular disk (6) also serves as a scraper ring.
