  • Publication number: 20220373080
    Abstract: A selector lever assembly for selecting and shifting to various driving modes in a vehicle transmission may include a rotary knob that is connected to a shaft element supported in a housing, where the driving modes are assigned to the rotational range of the shaft element, and separated from one another by a latching contour that can be felt by a driver, and where the rotation of the shaft element can be blocked by a locking contour, and where the shaft element is connected to a disk element for conjoint rotation, but can be displaced axially in order to activate and deactivate at least one further function mode.

  • Publication number: 20210265996
    Abstract: A rotary switch apparatus contains a rotary switch that has a moving operating element that contains a magnetic device for generating a magnetic field. The rotary switch apparatus also contains a Hall sensor device that is configured to generate a sensor signal representing a characteristic of the magnetic field, to determine a position signal using the sensor signal, which indicates a rotation position of the operating element about an actuation axis and a longitudinal position of the operating element along the actuation axis.

  • Publication number: 20160245394
    Abstract: The current embodiments provide a coupling element for a shift lever for a vehicle transmission. The coupling element may include a passage for receiving a section of the shift lever and a ring with a bore configured to receive the section of the shift lever. The ring may be installed in a ring holder of the passage, where the ring holder is configured to pivotally hold the ring.

  • Patent number: 7272988
    Abstract: A shift knob (1) for a gearshift lever (3) of an automatic transmission of a motor vehicle has a locking bar (5) guided axially in the gearshift lever (3) and a release button (2) which can be actuated manually for actuating the locking bar (5) in relation to the gearshift lever (3). The release button (2) is arranged in the shift knob (1) at the top end of the gearshift lever (3). The release button (2) is connected to the shift knob (1) by means of at least one lever arm (16) via a mounting site (17). The length of the lever arm (16) of the release button (2) is selected such in relation to the path traveled by the release button (2) during the actuation that the release button (2) performs an essentially linear movement.
