Publication number: 20200332839Abstract: A damping arrangement for dampening rotational irregularities in a drive train of a motor vehicle, having a slip arrangement providing slip between an input and output region of a torque-transmitting arrangement. The slip arrangement has a closed-loop control device that performs closed-loop control of the slip dependent on a measured signal for a rotational irregularity. The closed-loop control device performs closed-loop control of the slip dependent on at least one characteristic variable of a periodic oscillation component of an alternating component of a rotational speed proceeding from an average rotational speed. A sensor device is connected to the closed-loop control device and is designed to ascertain the average rotational speed in the torque-transmitting path downstream of the slip arrangement and to ascertain a frequency of the alternating component in the torque-transmitting path upstream of the slip arrangement.Type: ApplicationFiled: September 19, 2018Publication date: October 22, 2020Inventors: Tobias DIECKHOFF, Mathias KOPP, Alfred TAREILUS, Christofer EBERT

Publication number: 20200309232Abstract: A torque transmission arrangement for a powertrain of a motor vehicle includes an input and an output. A torque path runs from the input to the output. A torsional vibration damping unit is positioned first, followed by a gear unit, along the torque path between the input and the output. A first slip arrangement and/or a second slip arrangement for generating a speed slip are/is provided in the torque path between the input and the output for vibration damping.Type: ApplicationFiled: May 29, 2017Publication date: October 1, 2020Inventors: Tobias HÖCHE, Tobias DIECKHOFF, Daniel LORENZ, Andreas ORLAMÜNDER, Ingrid HOFFELNER, Wolfgang GROSSPIETSCH, Steffen MATSCHAS, Johannes FRIESS, Christofer EBERT, Matthias KRAM, Dennis EGLER, Axel ROHM, Erwin WACK, Bernd UNSELD, Thomas DOGEL, Matthias REISCH

Patent number: 10704619Abstract: A method for the transmission and damping of a mean torque with a superposed alternating torque in an arrangement having an input and an output. The mean torque and superposed alternating torque are transmitted along a path from the input to the output. A slip arrangement is provided in the torque path between the input and the output for transmitting mean torque and superposed alternating torque and for generating a speed slip between an input speed and an output speed in the path. The slip arrangement provides a maximum of an external activation of the speed slip in the area of the maxima of at least one periodic oscillation component of the alternating component and provides a minimum of an external activation of the speed slip in the area of the minima of at least one periodic oscillation component of the alternating component.Type: GrantFiled: May 29, 2017Date of Patent: July 7, 2020Assignee: ZF Friedrichshafen AGInventors: Tobias Höche, Tobias Dieckhoff, Daniel Lorenz, Andreas Orlamünder, Ingrid Hoffelner, Wolfgang Grosspietsch, Steffen Matschas, Johannes Friess, Christofer Ebert, Matthias Kram, Dennis Egler, Axel Rohm, Erwin Wack, Bernd Unseld, Thomas Dögel, Matthias Reisch, Christoph Sasse, Mathais Kopp
