SELECTABLE ONE-WAY CLUTCH

摘要

A selectable one-way clutch includes pawl members provided to a held plate rotatably via a spindle; a selector plate rotatable between a lock position where the pawl members are protrudable from the held plate and a release position where the pawl members are kept in a state the pawl members are housed in the held plate side by contacting a non-formation portion where no aperture is formed; and a device which restricts an operation of the pawl members by using volume change of material whose volume changes according to temperature change, so that the pawl members are more restricted to protrude from the first plate as an environmental temperature gets lower.

主权项

1. A selectable one-way clutch comprising:
a first plate and a second plate which are disposed on an axial line shared with each other; at least one pawl member, each being provided to the first plate rotatably via a spindle in such a manner that the pawl member is capable of protruding from the first plate toward the second plate, and, in a case of protruding from the first plate, engages with a recess formed in the second plate only when the second plate is rotating in a predetermined one rotational direction; a selector plate where at least one aperture which the pawl member is allowed to pass through is formed, the selector plate being rotatable relatively to the first plate between a lock position where the pawl member is allowed to protrude from the first plate by passing through the aperture and a release position where the pawl member is kept in a state that the pawl member is housed in a first plate side by contacting a non-formation portion where no aperture is formed; and a device which restricts an operation of the pawl member, by using volume change of material whose volume changes according to temperature change, so that the pawl member is more restricted to protrude from the first plate as an environmental temperature gets lower.
