Publication number: 20240146133Abstract: An electric machine has a stator and a rotor which is rotatably mounted relative to the stator. The rotor has a rotor shaft and a rotor body which is rotationally fixed to the rotor shaft. The rotor shaft has a hydraulic channel which extends in the axial direction, can be filled with a hydraulic fluid, and from which a first radial fluid channel extends outwards in the radial direction. At least one ring disc-shaped cover element is rotationally fixed to the rotor body on an axial end face of the rotor body, and the cover element together with the axial end face of the rotor body forms at least one first cooling channel which is open on both sides and which can be hydraulically coupled to the first radial fluid channel such that a hydraulic fluid can be conveyed out of the hydraulic channel of the rotor shaft and through the radial fluid channel and the first cooling channel in the radial direction in a centrifugal force-supported manner.Type: ApplicationFiled: March 1, 2022Publication date: May 2, 2024Applicant: Schaeffler Technologies AG & Co. KGInventors: Florian Nachtmann, Laurent Ineichen, Matthias Bauer, Kay Juckelandt

Publication number: 20230417293Abstract: A wet multi-plate clutch includes a plate carrier with a pair of fluid passage openings and a friction plate rotationally fixed and axially displaceable relative to the plate carrier. The friction plate has a carrier element and a pair friction pads fastened to the carrier element and delimiting a groove. The groove includes a groove geometrical center line. The groove geometrical center line may extend radially through a one of the pair of fluid passage openings, or it may extend radially between the pair of fluid passage openings. If the groove geometrical center line extend radially between the pair of fluid passage openings, one of the pair of friction pads may include a pad geometrical center line extending along a radial extent through a one of the pair of fluid passage openings.Type: ApplicationFiled: October 25, 2021Publication date: December 28, 2023Applicant: Schaeffler Technologies AG & Co. KGInventors: Christian Denda, Stefan Steinmetz, Florian Krebs, Jens Kramer, Laurent Ineichen, Tobias Hebgen

Publication number: 20220145954Abstract: An electric wheel drive unit (1) for driving a wheel of a motor vehicle is provided having a brake device (2) for braking the electric wheel drive unit (1) during operation, and a housing (3) which accommodates the brake device (2) in its interior (I). The brake device (2) is designed to convert kinetic energy into heat in order to perform braking, and to suck in a fluid in the axial direction (A) and to feed it in the radial direction (R) in order to cool the brake device (2) by a flow of fluid which is for the most part oriented radially and flows through the brake device (2).Type: ApplicationFiled: February 26, 2020Publication date: May 12, 2022Applicant: Schaeffler Technologies AG & Co. KGInventors: Philippe WAGNER, Aurelien GRAUSS, Simon ORTMANN, Laurent INEICHEN

Patent number: 7975474Abstract: A hydraulic system including a pump for feeding hydraulic fluid from an inlet side to an outlet side. A pressure accumulator is disposed at the outlet side, and between the pump and the pressure accumulator a hydraulic control valve is disposed, which has at least two valve positions. The outlet side of the pump is connected to the pressure accumulator in a second valve position, and is separated from the pressure accumulator in a first valve position. The outlet side of the pump is connected to the inlet side through the control valve in the first valve position.Type: GrantFiled: March 5, 2008Date of Patent: July 12, 2011Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Martin Staudinger, Laurent Ineichen, Marco Grethel, Eric Müller

Patent number: 7926637Abstract: A device for damping vibrations, in particular a torsion vibration damper with a primary component and a secondary component, coupled together through a torque transfer device and a damping coupling device. The torque coupling device includes a ramp mechanism for converting a rotation of one of the two elements, primary component or secondary component, into an axial force proportional to the input moment, which acts upon the other element. A device for compensating the resulting axial forces for generating an opposing force, opposing the resulting axial force, wherein the input moment is designed for a mean input torque. A conversion device is also provided, which directly converts an occurring force difference between the resulting axial force and the opposite force into a control variable for operating an actuation device in the device for damping vibrations, whereby an adaptation of the opposite force is performed.Type: GrantFiled: October 16, 2007Date of Patent: April 19, 2011Assignee: Schaeffler Technologies GmbH & Co. KGInventors: Eugen Kremer, Laurent Ineichen, Christian Huegel
