Abstract: An assembly for the selective coupling of two coaxially arranged shafts, comprising a first shaft and a second shaft arranged coaxially, a selector unit for selectively coupling the first shaft to the second shaft and including an electric motor, a selector fork, and a sliding sleeve connected to the selector fork to allow an adjusting action. The first shaft has a first external tooth system, at least in some section or sections, and the second shaft has a second external tooth system, at least in some section or sections. The first external tooth system is in engagement with an internal tooth system of the sliding sleeve and the second external tooth system can be brought into engagement with the internal tooth system of the sliding sleeve. A first tooth system formed on an output shaft of the electric motor is in engagement with a second tooth system of a gear segment, wherein the gear segment is arranged in a fixed manner on the selector fork.

Abstract: A device for actuating a clutch-controlled transfer case including a rotatable selector shaft, a clutch cam disk rotatable about a clutch cam disk axis by means of the selector shaft and having a gate, and at least one scissor lever having an end guided in the gate. The gate has at least one curved portion having a continuously increasing radial distance from the clutch cam disk axis. The clutch cam disk defines an opening about the clutch cam disc axis, and the clutch cam disk defines a pair of stops extending radially into the opening. The selector shaft is rotatably positioned in the opening. The selector shaft includes a stopping member in radial alignment with the pair of stops such that the selector shaft can be rotated with respect to the clutch cam disk between two stops.

Abstract: The invention relates to a device for actuating a clutch-controlled transfer case having a two-stage intermediate gearing and a clutch-controlled transfer case that has a two-stage intermediate gearing and that is equipped with such a device.
