Patent number: 9303754Abstract: The invention relates to a clutch assembly of a motor vehicle, in particular to a clutch-controlled differential unit, having a switchable clutch device which can transmit the drive power from a drive element which is at the drive input side in relation to the clutch device to a drive element which is at the drive output side in relation to the clutch device, wherein an oil delivery device is provided for the oil lubrication of the clutch, which oil delivery device, in an operating-state-dependent manner, delivers oil of an oil circuit which serves the clutch device. The clutch assembly is mounted in a housing which forms a clutch chamber for the clutch device. In order to permit rapid deoiling of the clutch chamber in situations in which the clutch device is opened, a deoiling device is provided which actively deoils the clutch chamber when the deoiling unit is not imparting a delivery action.Type: GrantFiled: September 25, 2012Date of Patent: April 5, 2016Assignee: GKN Driveline Koping ABInventors: Hans-Peter Nett, Jan Haupt

Patent number: 8398523Abstract: A drivetrain for an all-wheel-drive vehicle which has a first driven axle and a second driven axle. A drive unit is connected to a multi-stage transmission which has a multiplicity of gear stages for generating different transmission ratios. A transmission output shaft of the multi-stage transmission is connected to the first driven axle. The drive unit is also connected to an activating arrangement, the output element of which is connected to the second driven axle. Thus drive power can be supplied to the first axle permanently via the multi-stage transmission and drive power can be supplied to the second axle on demand via the activating arrangement. The activating arrangement has a first activating friction clutch and a second activating friction clutch which are designed to supply drive power to the second axle via a first and a second transmission ratio stage, respectively. The first transmission ratio stage is assigned to at least one lower gear stage of the multi-stage transmission.Type: GrantFiled: June 4, 2009Date of Patent: March 19, 2013Assignee: GETRAG Driveline Systems GmbHInventors: Hans-Peter Nett, Bernd Oberhausen, Michael Hoeck, Jan Haupt
