Patent number: 10233983Abstract: A process of controlling an actuating assembly for a coupling in the driveline of a motor vehicle, wherein the actuating assembly comprises a drive for moving an actuating element for operating the coupling unit, sensing a position signal representing the position of the actuating element; sensing a force signal representing the operating force required for displacing the actuating element; controlling the drive by means of an electronic control unit as a function of the position signal and the force signal. Further an actuating assembly is used for carrying out the process, as well as a drive assembly having such an actuating assembly.Type: GrantFiled: April 4, 2014Date of Patent: March 19, 2019Assignee: GKN Automotive LimitedInventors: Mark Schmidt, Frank Bernreuther, Kai Sorge, Rudolf Fitz, Stephan Leven

Patent number: 8152475Abstract: In a method for controlling operation of a compressor, the compressor is shut off by a control device in order to prevent thermal damages when an estimated temperature value Ts calculated by said control device exceeds an upper threshold value Tmax while the compressor remains on or is allowed to be turned on when there is a need for compression and a lower threshold value Tmin is not reached. In order to be able to more accurately estimate the estimated temperature and increase the thermal availability of the compressor, the estimated temperature value Ts is indirectly and cyclically determined by means of a mathematical-physical model that characterizes the cooling and heating properties of the compressor.Type: GrantFiled: April 10, 2004Date of Patent: April 10, 2012Assignee: Continental AktiengesellschaftInventor: Kai Sorge

Patent number: 7806797Abstract: An axial setting device includes two discs which are centered on a common axis. One is axially supported and the other one is axially displaceable, and at least one is rotatingly drivable. The two discs on their end faces, each have a plurality of circumferential ball grooves. The ball grooves each comprise a depth which decreases in the same direction, and each pair of opposed ball grooves accommodates a ball. At least the ball grooves of one of the two discs, starting from the region of the greatest groove depth, comprise a first groove portion with a greater pitch and an adjoining second groove portion with a smaller pitch, wherein the first groove portion extends over a smaller circular-arch-shaped portion than the second groove portion.Type: GrantFiled: October 24, 2006Date of Patent: October 5, 2010Assignee: GKN Driveline International GmbHInventors: Theodor Gassmann, Mark Schmidt, Kurt Müller, Kai Sorge

Publication number: 20090163313Abstract: A differential assembly 2 for variable torque distribution in the drive line of a motor vehicle. A differential gear 21 with a rotationally drivable differential cage 4 and two output shafts 3, 3?, which are drivingly connected to the differential cage 4 by means of a differential gear set 7, 9, 9?, wherein a first drive train is formed. A gear stage 14, 14? per output shaft 3, 3?, which gear stage is drivingly connected on one side to the differential cage 4 and on the other side to one of the output shafts 3, 3? is part of a second drive train which is functionally parallel to the first drive train. Friction clutch 15, 15? are provided for each gear stage 14, 14? and ball ramp assemblies are provided for actuating the friction clutches, the ball ramp assembly having a plurality of ball grooves 44, 45; 44?, 45? of variable depth. A single electric motor 52 is drivingly connected to rotatably driveable discs 43; 43? of axial setting devices 16, 16?.Type: ApplicationFiled: December 2, 2006Publication date: June 25, 2009Applicant: GKN DRIVELINE INTERNATIONAL GMBHInventors: Theodor Gassmann, Mark Schmidt, Kai Sorge, Kurt Muller, Ralph Mertens
