Abstract

A device for switching on a drive train in a motor vehicle has a power divider for several drive trains, one of which is permanently coupled with a drive unit and the other of which can be connected to the drive unit. The device also has an input shaft (2, 42, 82, 142) and an output shaft (4, 44, 84, 144) which can be connected to the input shaft (2, 42, 82, 142) through a switchable coupling (10, 50, 90, 150) in the form of an axially actuated friction clutch. The friction clutch is actuated by two rings (28, 30; 68, 70; 108, 110; 168, 170) which are coaxial with the clutch disks and which can be rotated relative to each other through 180.degree.. One ring is an axially supported support ring (28, 68, 108, 168) and the other ring is a pressure ring (30, 70, 110, 170) which slides axially on one of the shafts. The rings bear against each other on paths which can be varied axially around the periphery.
