Patent number: 11486479Abstract: A high-speed hydrodynamic adjustable converter having a working chamber for forming a hydrodynamic working medium circuit wherein a pump wheel, a turbine wheel and a guide wheel are positioned in the working chamber. The working medium flows through the pump wheel centrifugally or centrifugally-diagonally; and the working medium flows through the turbine wheel centripetally or centripetally-diagonally. The inlet grate edge of the turbine wheel, with respect to an axis of rotation of the pump wheel and the turbine wheel, is positioned on a smaller or equal radius than an inlet grate edge of the pump wheel. The hydrodynamic converter has a first guide wheel in the working chamber before the pump wheel viewed in the direction of flow of the working medium, the guide wheel being arranged for purely centrifugal or diagonal-centrifugal throughflow of the working medium and is used to influence the power transmission.Type: GrantFiled: May 12, 2021Date of Patent: November 1, 2022Assignee: Voith Patent GmbHInventor: Reinhard Kernchen

Patent number: 8800504Abstract: A vehicle cooling circuit, especially an engine cooling circuit, including a cooling medium pump and a vehicle drive engine and/or other heat-generating assembly cooled by means of the cooling medium. The circuit includes a hydrodynamic retarder with the working medium of the hydrodynamic retarder simultaneously also being the cooling medium of the cooling circuit, and the hydrodynamic retarder operating as the cooling medium pump. The secondary blade wheel is associated with a brake or a drive running counter to the drive of the primary blade wheel in such a way that it can optionally be fixed in a first operating state (braking operation) or be driven counter to the rotational direction of the primary blade wheel and, in a second operating state (pumping operation), can partially or completely be released such that it circulates at the speed of the primary blade wheel or at a specified speed difference slower than the primary blade wheel.Type: GrantFiled: January 18, 2010Date of Patent: August 12, 2014Assignee: Voith Patent GmbHInventors: Reinhard Kernchen, Werner Adams
