  • Patent number: 10487886
    Abstract: A shift element (4) for an automatic transmission having a hydraulically actuable piston; at least one hydraulic duct (10); an axially movable first shift element half (3, 7) operatively connected to the piston; a second shift element half (8); a bearing carrier (9); a ring-shaped component (1); and a Hall sensor (6) in the bearing carrier (9). The first shift element half (3) has a notch-like encoder contour (5) for the Hall sensor (6). The ring-shaped component (1) is composed of a non-magnetic material transparent to the Hall sensor (6). The ring-shaped component (1) is designed and arranged on the outer diameter of the first shift element half (3), such that an air gap between the notch-like encoder contour (5) and the Hall sensor (6) is filled by the ring-shaped component (1), and hydraulic oil flows in the remaining region along the circumference of the first shift element half (3).

  • Patent number: 8808129
    Abstract: A transmission device (1) with a hydraulic system (4) comprising a main transmission pump device for supplying various transmission components with hydraulic fluid. The main transmission pump device is driven by torque applied to the transmission input shaft (2). A force flow between the transmission input shaft (2) and transmission output shaft (3) is produced by various hydraulically actuated transmission components. When the hydraulic system (4) is not supplied by the main transmission pump, the force flow is interrupted. The hydraulic system (4) has an auxiliary pump device (5) by virtue of which the hydraulic system (4) too can be supplied with hydraulic fluid. The auxiliary pump device (5) is driven by torque applied to the transmission output shaft (3) at least when the force flow is interrupted.
