Abstract: A drive unit for driving at least one wheel drive shaft, in particular of a wheelset axle, in particular a cross-drive for use in rail vehicles with a driving engine and a transmission assembly coupled thereto. The output of the transmission assembly is formed by a hollow shaft which is coupled via an articulated coupling to the wheel drive shaft, in particular the wheelset axle. A first braking subsystem and a second braking subsystem are embodied as disk brake systems, each comprising at least one brake disk. An attachment flange of the brake disk of one braking subsystem is embodied in integral fashion with the hollow shaft. Placement of the braking subsystems along the hollow shaft is disclosed.

Abstract: The invention relates to a drive unit for driving at least one wheel drive shaft, in particular of a wheelset axle, in particular a cross-drive for use in rail vehicles with a driving engine and a transmission assembly coupled thereto; the output of the transmission assembly is formed by a hollow shaft which is coupled to the wheel drive shaft, in particular the wheelset axle, via an articulated coupling; with a braking system. The invention is defined by the following features: the braking system comprises two braking subsystems; a first braking subsystem and a second braking subsystem; the braking subsystems are embodied as disk brake systems, each comprising at least one brake disk; an attachment flange of the brake disk of a braking subsystem is embodied in integral fashion with the hollow shaft.
