SELECTABLE ONE-WAY CLUTCH

摘要

A selectable one-way clutch that can limit damage on components in an overrunning mode is provided. The selectable one-way clutch comprises a shutter plate arranged in a notch plate. The shutter plate is moved radially outwardly by a centrifugal force resulting from a rotation of the notch plate to prevent an entrance of the leading end of a strut into a notch.

主权项

1. A selectable one-way clutch, comprising:
a first plate and a second plate opposed to each other while being allowed to rotate relatively with each other; a strut that is arranged on the first plate in a pivotal manner; a notch that is formed on the second plate; a first elastic member that pushes the leading end of the strut toward the notch to bring the strut into engagement with an engagement wall of the notch when the second plate is rotated in a predetermined direction; an opening edge formed in the notch that pushes the strut out of the notch when the second plate is rotated in an opposite direction to the predetermined direction; a shutter plate that is arranged in the second plate while being allowed to move radially outwardly to close the notch and radially inwardly to open the notch; and a second elastic member that pushes the shutter plate radially inwardly to open the notch; wherein the shutter plate is adapted to be moved radially outwardly when an elastic force of the second elastic member is overwhelmed by a centrifugal force resulting from a rotation of the second plate so as to prevent an entrance of the leading end of the strut into the notch.
