An axle drive () for a vehicle is provided, comprising a differential () and an electrical motor () in driving connection with said differential () via a disconnect (), wherein lubrication of said axle drive () is adjusted automatically by means of the position of said disconnect ().

Lubrication system for an axle drive

A disconnected, hydraulic disc coupling () in an AWD vehicle with a hydraulic cylinder () for its actuation is to be quickly connected or engaged. The effective piston area in the cylinder () is for that reason reduced during the connection phase.

Method for operating a hydraulic disc coupling in an AWD vehicle and a coupling therefore

An arrangement of a vehicle is provided having normal transverse engine/transmission normal two-wheel drive operation which can be selectively placed into four-wheel drive operation wherein a pump which powers the coupling or uncoupling can be positioned downstream of a power takeoff unit without utilization of an electrically powered pump or transmission powered pump.
