  • Publication number: 20250243932
    Abstract: A parking lock arrangement for a motor vehicle transmission includes a parking lock gear arranged on a transmission shaft by sliding onto a guide region (7) defined on the radially outward side of the component (2) via a guide region (6) formed on the radially inward side of the parking lock gear (4). In the final position, a recess (14) extending peripherally around the guide region (6) of the parking lock gear (4) has been axially brought into overlap with a recess (13) extending peripherally around the guide region (7) of the component. The parking lock gear (4) and the component are securable against each other via a securing ring. The securing ring engages partially radially into the recess (14) in the guide region (6) on the parking lock gear (4) and partially radially into the recess (13) in the guide region (7) on the component.

  • Patent number: 9644688
    Abstract: A clutch for an automatic transmission for a motor vehicle includes a clutch housing and a retaining ring. In an inner circumferential surface of the clutch housing concentrically at a central axis (M) of the cylinder jacket-shaped inner circumferential surface, a ring groove that is open radially inward is formed, within which the retaining ring is arranged. The retaining ring is thereby open and features two spaced ends. In the area of the ring groove, at least one stop is formed, whereas a distance between the ends from each other or the position of the stop is selected in such a manner that, in the assembled state, only one end of the retaining ring may come into contact with a stop, while the other end is spaced from this stop or an additional stop.
