Abstract

In the case of an axle drive unit with a power-shiftable two-speed transmission unit, in order to enable particularly simple and advantageous control of a gear change and to manage with a small number of components and a less complex control logic and control sensor system, the coordination of mechanically-passively implemented shifting thresholds of a friction clutch and a blocking device of a freewheel is provided, which makes it possible to control the friction clutch and the blocking device with the same control variable at always the same level.
