Publication number: 20240093735Abstract: A dog clutch arrangement for a motor vehicle having a clutch body. The clutch body has first teeth in a first toothing and an axially movable sliding sleeve arrangement with second teeth in a second toothing. The sliding sleeve arrangement has a shift ring and a sleeve with the second toothing. The shift ring and the sleeve at least partially overlap in axial direction and are arranged to be axially displaceable relative to one another. The shift ring and the sleeve enclose an intermediate space, a pneumatic damping which damps the movement of the sleeve and the shift ring relative to one another being formed with the intermediate space.Type: ApplicationFiled: January 18, 2022Publication date: March 21, 2024Inventor: Martin RUIDER

Patent number: 11739798Abstract: The disclosure relates to a claw coupling for interlockingly connecting a first rotatable component to a second rotatable component, wherein a sliding sleeve is non-rotatably and axially slidably arranged on the first rotatable component and a coupling body is non-rotatably arranged on the second rotatable component, the sliding sleeve being axially movable for interlocking connection to the coupling body in order to connect the first component to the second component, at least one spring-loaded shifting ring being movably mounted, non-rotatably and axially relative to the sliding sleeve, on the sliding sleeve, and a damping chamber, formed in dependence on the relative motion, is provided in order to delay the axial motion. The disclosure further relates to an electrical drive axle of a vehicle having at least the claw coupling. In addition, the disclosure relates to a method for interlockingly connecting the first rotatable component to the second rotatable component via a claw coupling.Type: GrantFiled: March 5, 2020Date of Patent: August 29, 2023Assignee: ZF Friedrichshafen AGInventors: Martin Ruider, Patrick Isele, Kim Führer, Marcel Müller, Matthias Winkel, Werner Herbert Brandwitte, Klaus Ventzke, Fernando Jesus Ramos Zuniga, Stephan Demmerer

Publication number: 20230160437Abstract: A claw clutch for positively connecting a first rotatable component to a second rotatable component. A claw clutch for motor vehicles having an electric drive train which permits a reliable connection of the claw clutch when tooth-on-tooth positions are released and, at the same time, reduces the number of moving elements on the sliding sleeve. A clutch body, which is arranged on the first rotatable component for conjoint rotation therewith, has a first tooth system and a sliding sleeve, which is arranged on the second rotatable component in a manner which allows conjoint rotation and axial movement, has a second tooth system and is axially movable via a shift fork by an actuator system in order to load a spring element by the actuator system in the case of a tooth-on-tooth position. The spring element to be loaded is arranged outside the second rotatable component equipped with the sliding sleeve.Type: ApplicationFiled: November 9, 2022Publication date: May 25, 2023Inventors: Norman SCHMIDT-WINKEL, Fabian HARTMANN, Ludwig GEIßELBRECHT, Martin RUIDER, Bastian SCHUH

Publication number: 20220314801Abstract: An operating device may have a moving operating element, a housing a magnetorheological elastomer, and a coil. An end of the operating element may be supported in the housing. The magnetorheological elastomer may result in a first operating characteristic for operating the operating element in a resting state and a second operating characteristic for the operation in an activated state. The coil may generate a magnetic field that transfers the magnetorheological elastomer between the resting state and the activated state.Type: ApplicationFiled: August 26, 2020Publication date: October 6, 2022Applicant: ZF Friedrichshafen AGInventors: Fabian Schrader, Michael Pantke, Martin Ruider, Magnus Sprehe, Rainer Haevescher, Artur Neumann, Thorsten Sander, Georg Tenckhoff, Erwin Biegger

Patent number: 11075042Abstract: An electromagnetic control mechanism for a switching element is described herein, which can be switched to an open operating state and to a closed operating state by means of an electromagnet and an actuating unit that acts counter to the actuation force of the electromagnet. The electromagnet has a dedicated mechanism for dampening the actuation movement of an anchor of the electromagnet toward a section of the coil, by means of which the actuation speed of the anchor can be reduced after a distance between a section of the anchor facing the coil and the section of the coil becomes shorter than a predefined distance.Type: GrantFiled: February 6, 2018Date of Patent: July 27, 2021Assignee: ZF FRIEDRICHSHAFEN AGInventors: Thomas Speh, Martin Ruider, Michael Pantke, Thomas Schwegler

Patent number: 10436259Abstract: An axially actuatable positive engagement clutch which includes an input shaft with an input toothing and an output shaft with an output toothing. An axially displaceable connection element can occupy a meshing position which is located in an actuation path (s) between the open position and the closed position and in which the driving toothing engages with the input toothing or the output toothing for the first time during the transition from the open position into the closed position. An actuation device is configured to displace the connection element from the closed position to the open position, and an elastic return element which applies a restoring force to the connection element in direction of the closed position. The return element has a force/deflection characteristic with a local force maximum (F1) which coincides in the actuation path (s) at least approximately with the meshing position of the connection element.Type: GrantFiled: November 8, 2016Date of Patent: October 8, 2019Assignee: ZF Friedrichshafen AGInventors: Martin Ruider, Michael Pantke, Johannes Winkler, Matthias Cudok, Martin Hain, Alexander Markow
