A reverse-input blocking clutch includes a pressed member having a pressed surface; an input member having an input-side engaging portion; an output member having an output-side engaging portion; an engaging element having a pressing surface, an input-side engaged portion, and an output-side engaged portion and arranged between the pressed surface and the output-side engaging portion with respect to a first direction which is a direction of moving toward or away from the pressed surface; an elastic member that elastically urge the pressing surface toward the pressed surface 7 in the first direction; and a displacement prevention means for preventing relative displacement in the axial direction of the engaging element with respires to the output member.

Reverse-input blocking clutch and manufacturing method thereof

An actuator with reverse input blocking clutch has a function of switching the reverse input blocking clutch to a state in which torque can be transmitted between an input member and an output member, in a state in which reverse torque is input to the output member from an output-side mechanism, by applying torque to the input member by an actuator in an opposite direction to a direction of the reverse torque, and then by giving an instruction to the actuator to apply torque having a magnitude smaller than a magnitude of the reverse torque to the input member in the opposite direction, transmitting the reverse torque to the input member.

Actuator with reverse input blocking clutch, steering device, and reverse input blocking clutch control method

A distance between a rotation center of an input member and a contact portion between an input side engaging portion and an input side engaged portion in a second direction is set to be shorter than a distance between a rotation center of an output member and a contact portion between an output side engaging portion and an output side engaged portion in the second direction. In a locked or semi-locked state, a contact portion between the output side engaging portion and the output side engaged portion is located on the side closer to the rotation center of the output member in a first direction in relation to a virtual line connecting the rotation center of the output member and a contact portion between one pressing surface of the pair of pressing surfaces and the pressed surface.

Reverse input blocking clutch

In a predetermined first state, a distance (D) in a second direction between a contact portion (P) between a input-side engaging part () and an input-side engaging part () and a rotation center (O) is larger than a distance (D) in the second direction between a contact portion (P) between an output-side engaging part () and an output-side engaged part () and the rotation center (O). In a locked state or a semi-locked state, a contact portion (C) between the output-side engaging part () and the output-side engaged part () is located closer to the rotation center (O) of the output member () in a first direction than an imaginary straight line (L) connecting a contact portion (C) between one pressing surface () of the pair of pressing surfaces () and a pressed surface () to the rotation center (O) of the output member ().

Reverse input cut-off clutch

A cam device having a drive cam and a driven cam; and a friction engagement device having at least one friction plate and at least one separation plate are provided. The friction engagement device is configured so as to be put into a connected state by pressing the friction plate and the separation plate against each other by the driven cam, and a disconnected state. Also provided are a rotation transmission state switching device having a first member and a second member coaxially arranged, and a mode selecting part configured to rotate or displace in the axial direction according to rotation of the drive cam. The rotation transmission state switching device has at least one mode of a free mode and a lock mode of the first member and the second member, and a one-way clutch mode.

Motive power transmission route switching device and two-speed transmission

In the centrifugal pendulum damper, a plurality of pendulums are swingably supported on a rotating body. The pendulum includes a swinging shaft serving as the swing center and a rolling shaft including a rolling surface on the outer periphery thereof. The rotating body includes a plurality of pendulum support portions, and the pendulum support portion includes a swinging shaft guide portion that guides the swinging shaft in a radial direction of the rotating body, and a rolling shaft guide portion that is in rolling-contact with the rolling surface of the rolling shaft to cause the pendulum to swing around the swing axis.
