  • Publication number: 20250145250
    Abstract: An arrangement for actuating a shift element of a gearbox includes a rotatably mounted and preloaded shift pawl (2) and a shift ring (3) with an outer toothing (4) and assigned to a gearbox element. A first end (8) of the shift pawl (2) is assigned to the outer toothing (4) of the shift ring (3) so as to lock or release the shift ring (3) in order to shift a gear stage, and a second end (9) of the shift pawl (2) is assigned to a shift gate (6) of a shift drum (5) that actuates the shift pawl (2). The shift pawl (2) is operatively connected to at least one double torsion spring (10) in order to apply a preload force.

  • Publication number: 20240343344
    Abstract: An actuating arrangement for a transmission includes a pivotable pawl (14) and a rotatable shift drum (10). By rotating in a first rotational direction from a first into a second angular position, the shift drum (10) is configured to push the pawl (14) with the actuating surface (20) out of an engaged position into a released position and by rotating in the second rotational direction from the second into the first angular position to enable the pawl (14) to drop out of the released position into the engaged position. The actuating arrangement includes an actuating device (30) configured to adjust the pawl (14) out of the released position into the engaged position. The pawl (14) is adjusted by the actuating device (30) out of the released position into the engaged position only in a third angular position of the shift drum (10) between the first and the second angular position.
