Patent number: 11339834Abstract: A conveying device is located inside a clutch device to amplify a fluid flow in an axial direction, i.e. parallel to a rotation axis of the clutch device, and hence the fluid flow can be kept sufficiently great even in the moved portions of a fluid line. The conveying device can be used in clutch devices which are arranged as separating clutches in a hybrid module. The conveying device allows even the complicated fluid lines within hybrid modules to be supplied with sufficient fluid at all times. The conveying device may be arranged at least on the first or second clutch side, and hence the quantity of conveyed fluid is dependent on the rotation speed.Type: GrantFiled: June 22, 2016Date of Patent: May 24, 2022Assignee: Schaeffler Technologies AG & Co. KGInventors: Johannes Weis, Steffen Huber, Jens Genter, Andreas Trinkenschuh, Gerold Steinel, Felix Vogel

Patent number: 11217801Abstract: A vehicle is provided having a vehicle front end in which a fuel cell system which has a fuel cell stack is arranged, which full cell system is, at a cathode side, connected at least directly to an exhaust-gas line through which a fluid emerging from the fuel cell stack can be discharged from the vehicle front end. The exhaust-gas system comprises a sorption system for the adsorption of a liquid of the fluid emerging from the fuel cell stack. The invention furthermore relates to a method for treating a fluid of a fuel cell system, which has a fuel cell stack, in a vehicle.Type: GrantFiled: October 1, 2018Date of Patent: January 4, 2022Assignee: Audi AGInventors: Thomas Lichius, Herbert Böll, Johannes Weis, Thomas Weustenfeld

Patent number: 10982584Abstract: The disclosure relates to a method for operating a drive device of a motor vehicle, wherein the drive device has at least one heat-generating device and a cooling circuit for cooling the heat-generating device, and at least one first coolant cooler of the cooling circuit and at least one second coolant cooler of the cooling circuit are fluidically connected to the heat-generating device. It is thereby provided that the first coolant cooler and the second coolant cooler are fluidically connected in parallel to the heat-generating device, and that coolant arriving from the heat-generating device be divided by means of a control mechanism between the first coolant cooler and the second coolant cooler. The disclosure furthermore relates to a drive device of a motor vehicle.Type: GrantFiled: July 18, 2018Date of Patent: April 20, 2021Assignee: Audi AGInventors: Thomas Weustenfeld, Thomas Lichius, Johannes Weis

Patent number: 10946712Abstract: A vehicle includes a fuel cell unit with which is associated a first coolant circuit, with a second coolant circuit associated with the interior of the vehicle, in which is held a coolant of lower temperature relative to the coolant of the first coolant circuit. Given higher demand for cooling capacity in the first coolant circuit, a valve is opened by a control device, independently of the heat demand in the second coolant circuit, to open a first connecting conduit between the first coolant circuit and the second coolant circuit, and thus, using a second connecting conduit, forms a common ring conduit for the first coolant circuit and the second coolant circuit with the accumulated coolant from the first coolant circuit and the second coolant circuit.Type: GrantFiled: October 5, 2018Date of Patent: March 16, 2021Assignee: AUDI AGInventors: Johannes Weis, Thomas Lichius, Thomas Weustenfeld

Patent number: 10224785Abstract: A cooling system for a dynamoelectric machine comprising a cooling jacket for assembly on an outer circumference of a stator of the dynamoelectric machine, a housing for receiving the stator having the mounted cooling jacket such that a hollow chamber, which can be filled with a liquid cooling medium, remains between an outer wall of the cooling jacket and an inner wall of the housing, wherein an inlet opening for inlet of the cooling medium into an inlet region and an outlet opening for outlet of the cooling medium from an outlet region of the hollow chamber are arranged on the housing and a barrier element connected to the cooling jacket for spatial separation of the inlet region from the outlet region is provided. The efficiency of such a cooling system is improved in that the barrier element presses against the inner wall of the housing having increasing pressure difference of the cooling medium in the inlet and outlet region.Type: GrantFiled: June 12, 2014Date of Patent: March 5, 2019Assignee: Schaeffler Technologies AG & Co.
