Patent number: 11692598Abstract: A one-way clutch, including: a case; a drive plate enclosed by the case and defining openings; a first plate non-rotatably connected to the case and defining a first opening; a rotatable actuator plate; a strut including a central portion, an engagement portion, and a control portion; and a spring. In a locked mode: the spring pivots the engagement portion into an opening of the drive plate, a rotation of the drive plate in a first direction is enabled, and a rotation of the drive plate in a second direction is blocked. To transition from the locked mode to a free-wheel mode, in which the rotation of the drive plate in the second direction is enabled, the actuator plate is rotated by an actuator to contact the control portion and pivot the strut to displace the engagement portion out of the opening of the drive plate.Type: GrantFiled: September 28, 2021Date of Patent: July 4, 2023Assignee: Schaeffler Technologies AG & Co.
