  • Patent number: 11053990
    Abstract: Systems and method for a two-way clutch are provided. In some configurations, the two-way clutch includes a driven member having a first mating surface, a drive member having a second mating surface, and a locking mechanism arranged between the first mating surface and the second mating surface. The locking mechanism is operable to contact the first mating surface and the second mating surface, in response to an outside force applied to the drive member that loads the locking mechanism. The two-way clutch further includes an engaging member. The engaging member provides a predetermined interference on the locking mechanism to hold the locking mechanism off of at least one of the first mating surface and the second mating surface, when the locking mechanism is in an unloaded state.

  • Patent number: 11053988
    Abstract: A vehicle powertrain system and powertrain actuator therefor is provided. The powertrain actuator selectively couples a first rotatable member to a second rotatable member to transfer torque therebetween and selectively decouples the first rotatable member from the second rotatable member to prevent the transfer of torque therebetween. The powertrain actuator includes a tubular cam assembly having a tubular first member and a tubular second member. The tubular first and second tubular members have end surfaces that interact with one another upon energizing a unidirectional solenoid. Upon a first energization of the solenoid, the first and second tubular members interact to operably couple the first and second rotatable members to allow torque to be transferred therebetween, and upon a second energization of the solenoid, the first and second tubular members interact to selectively decouple the first the second rotatable members to prevent the transfer of torque therebetween.

  • Patent number: 11047435
    Abstract: A method for actuating a clutch with a clutch actuation system, wherein an axially moveably mounted first piston (4) arranged on a master-side is moved via an electric motor, and the movement thereof is transmitted via a hydraulic section (8) to a second piston (10) positioned on a slave-side, which second piston actuates the clutch (11), wherein a path change triggered by the movement is measured and evaluated. In a method, in which a path change can be immediately measured, the path change of the clutch (11) detected on the slave-side is converted into an acoustic signal, which is transmitted via the hydraulic section (8) to the master-side for evaluation.

  • Patent number: 11047433
    Abstract: This clutch includes an annular clutch housing, a rotationally driven drive-side rotating body, a driven-side rotating body, a rolling body, and a support member. The clutch is configured such that, when the drive-side rotating body starts to rotate when driven, the drive-side rotating body comes into contact with the support member in a rotational direction and presses the rolling body in the rotational direction through the support member, thereby releasing the rolling body from gripping effected by the clutch housing and the driven-side rotating body. The support member includes a load generation section for generating a load which makes it difficult for the support member to rotate about the rotation axis of the drive-side rotating body when at least the drive-side rotating body starts to rotate when driven.
