Problems solved by technology

[0004] However, in the optional one-way clutch described in U.S. Patent No. 9188170, since one end of the strut protrudes completely from the cover plate, the stand-up angle of the strut increases, and the stroke amount of the hydraulic piston increases.
Therefore, it is necessary to install a hydraulic chamber to secure a predetermined stroke inside the optional one-way clutch, resulting in an increase in size.
[0005] In addition, in the structure described in U.S. Patent No. 9188170, since the notched plate is kept in a state near the pocket plate, even in the state where the hydraulic piston is retreated, if the pillar moves to the notched plate side due to disturbance such as vibration, stand up, also cause the strut to collide with the notch plate in rotation
Repeated collisions may lead to wear and tear of the props, which may reduce the durability of the props.

Embodiment Construction

[0041] Hereinafter, an optional one-way clutch in an embodiment of the present invention will be specifically described with reference to the drawings.

[0042] refer to Figure 1 ~ Figure 3 , to illustrate the overall structure of the selectable one-way clutch (hereinafter referred to as "SOWC"). It should be noted that "axial" in this description means figure 1 The direction of the rotation axis O of the SOWC indicated by the single-dot chain line in . "Rotation" means that the rotating part rotates about the axis of rotation O. In addition, one rotation direction is described as "forward direction", and the rotation direction opposite to the normal direction is described as "reverse direction". In addition, when describing a structural member, one surface in the axial direction may be described as "front surface", and the other surface in the axial direction may be described as "back surface".

[0043] Such as figure 1 As shown, the SOWC1 has a pocket plate 2 , a notch...

Abstract

The present invention relates to a selectable one-way clutch. The selectable one-way clutch includes a pocket plate, a notch plate, a cover plate, and plate-like struts. A one end portion of each strut is provided with an engagement surface and a projecting portion. Each strut comes into an erect state in which the engagement surface of the strut erects from the other surface of the cover plate toward the notch plate side. The selectable one-way clutch moves the notch plate in the axial direction to change a distance in the axial direction between the pocket plate and the notch plate, therebycarrying out switching between an out-of-engagement state in which the erecting struts cannot contact with the notches and a one-way clutch state in which the erecting struts can contact with the notches.

Description

technical field [0001] This invention relates to selectable one-way clutches. Background technique [0002] As a kind of one-way clutch, the following selectable one-way clutch (SOWC) is known, in which the selectable one-way clutch (SOWC) can be selectively switched only in one direction of rotation. The engaged one-way clutch state and the idling state that cannot be engaged. [0003] In U.S. Patent No. 9,188,170, a selectable one-way clutch is described. The selectable one-way clutch has: a pocket plate in which pillars are accommodated in a plurality of pockets (accommodating recesses); a plurality of recesses ( The pocket plate, the notch plate and the cover plate are assembled together. In this optional one-way clutch, the annular hydraulic piston is reciprocated in the axial direction to switch between a state in which the strut is raised toward the notch plate and a state in which the strut is housed in the pocket. As a result, the one-way clutch state and the idl...
