摘要： A selectable one-way clutch includes: a pocket plate including accommodating recess portions; a notch plate including engaging recess portions; a plate-shaped engaging piece; and a selector plate configured to switch between: a state in which the engaging piece rises toward the notch plate; and a state in which the engaging piece is accommodated in the accommodating recess portion. The notch plate includes a plane portion including a first inclined surface, and the first inclined surface provides the engaging piece with force in a direction into which the engaging piece is urged away from the notch plate, when the notch plate is rotated in an engaging direction into which the engaging piece rising toward the notch plate is engaged with the engaging recess portion, and one end portion of the engaging piece rises toward the notch plate and comes in contact with the plane portion.

摘要： A selectable one-way clutch includes: a pocket plate including pockets provided along a circumferential direction on one surface; a notch plate that is rotatable with respect to the pocket plate, the notch plate including notches provided along a circumferential direction on a surface facing the one surface; struts that are plate-shaped and housed in the respective pockets; and a selector plate disposed between the pocket plate and the notch plate, and configured to switch, by rotating coaxially with the pocket plate, between: a state in which the struts have risen toward the notch plate; and a state in which the struts are housed in the respective pockets. The notch plate includes flat portions between the notches that are adjacent in the circumferential direction, and each flat portion includes a first recess at a position where the corresponding strut having risen toward the notch plate is brought into contact.

摘要： A selectable one-way clutch includes a pocket plate, a notch plate, and a selector plate, and the selector plate is configured to rotate so as to switch the clutch between an engaged state and a non-engaged state. A lubricant passage through which a lubricant is supplied to the selectable one-way clutch has a lubricant inlet and a lubricant outlet, and the lubricant outlet is located on the lower side of the lubricant inlet in a direction of gravitational force, and connected to an inside of the selectable one-way clutch. The lubricant passage includes an inclined surface that is inclined with respect to the direction of gravitational force, between the lubricant inlet and the lubricant outlet, and the inclined surface has an opening.

摘要： An intermesh engagement device includes an intermesh engagement mechanism, a moving member, an actuator configured to apply a thrust to a moving member in an engaging direction, a transmission spring configured to transmit the thrust of the actuator from the moving member to a sleeve, a return spring, a stopper, and an electronic control unit configured to control the actuator. The electronic control unit is configured to execute first control for setting the thrust of the actuator to a thrust in a first region, and, when a halfway stopped state has occurred through the first control, execute second control for setting a thrust larger than the thrust in the first control. The first region is a range in which the thrust is larger than an urging force of the return spring and is smaller than the sum of the urging force of the return spring and a maximum urging force of the transmission spring.

摘要： A drive control device includes: a meshing engagement unit; an engine; a rotary machine; a detector detecting a predetermined parameter; and a controller configured to perform a release control of causing the rotary machine to output a second rotation torque in a direction opposite to a first rotation torque applied from the engine to the engagement unit at a time the engagement unit is released. The release control includes setting a magnitude of the second rotation torque to a predetermined value larger than a magnitude of the first rotation torque at a time the predetermined parameter change degree is not smaller than a threshold value and gradually decreasing the magnitude of the second rotation torque, and setting the magnitude of the second rotation torque to a magnitude smaller than the predetermined value at a time the predetermined parameter change degree is smaller than the threshold value.

摘要： An ECU of an engaging device is configured to feedback-control a current value so as to realize an engagement indicator current required for moving a sleeve in a position in an axial direction in which dog teeth may mesh with dog teeth in engaging operation. This performs releasing operation based on temporal transition of the current value during the engaging operation.
