Abstract

A selectable one-way clutch is provided. The selectable one-way clutch is shifted between overrunning mode and engagement mode by rotating a selector plate interposed between a notch plate and a pocket plate. The selectable one-way clutch comprises: a plunger that is connected to the selector plate and that is reciprocated by the actuator; a thermally shrinkable stopper member that is fitted onto the plunger; and a stationary member to which the stopper member is brought into abutment by a reciprocating motion of the plunger.

First claim

What is claimed is:

1. A selectable one-way clutch, in which a notch plate is selectively brought into engagement with a pocket plate by rotating a selector plate interposed therebetween by an actuator, comprising:
a plunger that is connected to the selector plate and that is reciprocated by the actuator;
a stopper member that is fitted onto the plunger; and
a stationary member to which the stopper member is brought into abutment by a reciprocating motion of the plunger;
wherein the stopper member is made of heat-shrinkable material such that the plunger is configured to perform the reciprocating motion when the stopper member is thermally expanded, and the stopper member is configured to restrict the reciprocating motion of the plunger when the stopper member is thermally shrunk, and
wherein the stopper member is brought into abutment with the stationary member by the reciprocating motion of the plunger in a direction to bring the notch plate into engagement with the pocket plate.

2. The selectable one-way clutch as claimed in claim 1 ,
wherein the stopper member includes a ring fitted onto the plunger, and
wherein the ring is made of the heat-shrinkable material to be fitted tightly on the plunger when the ring is thermally shrunk.

3. The selectable one-way clutch as claimed in claim 1 ,
wherein the stopper member includes a ring fitted onto the plunger,
wherein an annular groove is formed on the plunger, and
wherein the ring is made of the heat-shrinkable material in such a manner that an inner circumferential portion thereof enters into the annular groove when the ring is thermally shrunk.
