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: 10738839Abstract: A clutch arrangement is formed with drive-side and, output-side clutch elements and a clutch piston for operative connection and disengagement between the drive-side and output-side clutch elements. Associated with at least two clutch elements is an elastically deformable clutch element working mechanism through which the corresponding clutch elements can be acted upon in direction away from one another by an axial force to assist disengagement of the drive-side and output-side clutch elements. The clutch element working mechanism provides a considerable change in the gradient of the axial force exerted on the clutch elements as a result of even a small change of shape of the clutch element working mechanism so that a sharply rising axial force of the clutch element working mechanism works against the clutch piston.Type: GrantFiled: August 1, 2016Date of Patent: August 11, 2020Assignee: ZF Friedrichshafen AGInventors: Johannes Friess, Christoph Sasse, Wolfgang Grosspietsch, Angelika Ebert, Axel Rohm, Steffen Romeis

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

Patent number: 10704620Abstract: A method for transmission of and damping of a mean torque with a superposed alternating torque in a torque transmission arrangement for a powertrain of a motor vehicle having an input and an output. The mean torque with the superposed alternating torque is transmitted along a torque path from the input the output. The input rotates at an input speed and the output rotates at an output speed. A slip arrangement is provided in the torque path between the input and the output for generating a speed slip. The slip arrangement provides a maximum of an external activation of the speed slip in the area of a maxima of at least one periodic oscillation component of an alternating component and provides a minimum of an external activation of the speed slip in the area of a minima of at least one periodic oscillation component of the alternating component (new).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, Lukas Spath, Angelika Ebert
