Abstract: A drive converter device is provided for converting a rotational drive of a drive device into a translational actuation movement for a shifting element of a transmission unit with a cam disk that is rotatable and adjustable in an axial direction is described. The cam disk is formed with track areas with defined gradients, in the area of which the cam disk is in operative connection with at least one fixed-housing element. The cam disk is translationally adjustable in respect of the elements through rotational movement of the cam disk, depending on the gradients of the track areas. Furthermore, an axle transmission device with a shifting element is described; in the area of which, an operative connection between a shaft of a differential and a shaft connectable with a wheel of a vehicle axle is able to be produced. The shifting element is able to be actuated by the drive converter device.

Abstract: A drive converter device (19) in accordance with the invention for converting a rotational drive of a drive device (20) into a translational actuation movement for a shifting element (18) of a transmission unit (8) with a cam disk (21) that is rotatable and adjustable in an axial direction is described. The cam disk (21) is formed with track areas (22, 23) with defined gradients, in the area of which the cam disk (21) is in operative connection with at least one fixed-housing element (24 to 26), such that the cam disk (21) is translationally adjustable in respect of the elements (24 to 26) through the rotational movement of the cam disk (21), depending on the gradients of the track areas (22, 23). Furthermore, an axle transmission device (8) with a shifting element (18) is described; in the area of this, an operative connection between a shaft (14B) of a differential (13) and a shaft connectable with a wheel of a vehicle axle is able to be produced.
