Patent number: 11767889Abstract: A cooling oil guiding device for a clutch actuatable by an axially movable piston. The piston is radially inward of the clutch, and separates a pressure space and a compensation space. The compensation space is delimited by an axially stationary compensation space cover and a seal cover coupled to the piston. The compensation space cover and the seal cover axially overlap radially outwardly and are axially movable relative to one another via a sealing element. An overflow opening connects the compensation space to an oil channel in the seal cover between the seal cover and the piston, the oil channel opens radially outward. A control edge is provided at a component part axially immovable relative to the piston, by which an oil flow exiting from the oil channel is guided through the clutch when the clutch is closed and is guided past the clutch when the clutch is open.Type: GrantFiled: April 16, 2020Date of Patent: September 26, 2023Assignee: ZF FRIEDRICHSHAFEN AGInventors: Steffen Matschas, Axel Rohm, Ingo Krafft, Monika Rößner, Angelika Ebert, Julian Larbig

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: 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
