SELECTABLE ONE-WAY CLUTCH

摘要

A selectable one-way clutch adapted to prevent an undesirable engagement is provided. The selectable one-way clutch comprises a drag increasing device that increases a drag of oil acting between the pocket plate and the selector plate against a force rotating the selector plate in a direction to bring the selectable one-way clutch into the engagement mode.

主权项

1. A selectable one-way clutch, comprising:
a pocket plate; a notch plate that is opposed to the pocket plate; a selector plate that is interposed between the pocket plate and the notch plate while being allowed to be rotated by an actuator relatively with the pocket plate and the notch plate within a predetermined angle to selectively switch an operating mode of the selectable one-way clutch between an overrunning mode in which the notch plate is allowed to rotate relatively with the pocket plate in both directions without transmitting torque, and an engagement mode in which the notch plate is brought into engagement with the pocket plate to enable torque transmission in one direction; a lubrication oil applied between the pocket plate and the notch plate; and a drag increasing device that increases a drag acting between the pocket plate and the selector plate against a force rotating the selector plate in a direction to bring the selectable one-way clutch into the engagement mode.
