  • Publication number: 20200309165
    Abstract: A hydraulic control unit (4) includes a valve bush (12), a valve cover (15) partially closing the valve bush (12) on an end face (S1), a valve slide (13) guided in a longitudinal direction (L) within the valve bush (12), and a housing part (6). The housing part (6) includes a recess (8) matching an external contour of the valve bush (12). An intermediate plate (7) is configured to partially cover the valve cover (15). A spring (14) is arranged within the valve bush (12) and preloads the valve slide (13) in a starting position. The valve bush (12) is inserted, together with the valve cover (15), the valve slide (13), and the spring (14), into the recess (8) of the housing part (6) and jointly form a hydraulic valve (9). The valve bush (12) forms an inlet (19), and the valve cover (15) forms an outlet (31).

  • Patent number: 10731758
    Abstract: A parking lock having a locking pawl engageable into a parking interlock gear, a connecting rod with an interlocking element to prevent the parking lock from disengaging when in the locked condition, a spring for engaging the parking lock, a hydraulically actuatable actuator for disengaging the parking lock, and an emergency release device for emergency disengagement of the parking lock. The piston is articulatedly connected to a first disk rotatably mounted on a selector shaft, a second disk connected to the selector shaft in a torsion-proof manner is articulatedly connected to the connecting rod, the spring is tensioned between the transmission housing and the second disk, and the emergency release device is connected to the selector shaft in a torsion-proof manner. The first disk is operatively connected to the second disk such that rotation of the second disk by the emergency release device does not rotate the first disk.

  • Publication number: 20200063770
    Abstract: A device for fixing a directly controlled valve (1) acting as an actuator in a valve housing (2), in a duct plate, or in a transmission housing, the device being fixed to the valve housing (2), the duct plate, or the transmission housing by fixing elements (7), the device including a fixing plate (3) having a spring-loaded length (L). The spring-loaded length (L) is adjustable independently of a distance of the fixing elements (7) from a central axis (4) of the actuator.
