Abstract:
A selectable one-way clutch is provided. The selectable one-way clutch comprises a selector member rotated at a predetermined angle between an engagement position and a disengagement position, and an actuator that reciprocates linearly along a tangential line of the selector member to rotate the selector member to the engagement position and to the disengagement position. The actuator comprises an actuation member that is offset from the selector member in a direction along a rotational center axis of the selector member to actuate along the tangential line of the circumference of the selector member. The selectable one-way clutch further comprises an arm connecting the actuation member and the selector member to rotate the selector member by a linear motion of the actuation member.
Abstract:
A locking member for controllably transmitting torque between first and second coupling members of a coupling assembly is provided. The locking member includes projecting inner and outer pivots which extend laterally from a main body portion for enabling pivotal motion of the locking member about a pivot axis which intersects the pivots. The pivots are sized, shaped and located with respect to the main body portion to allow frictional engagement of an end surface of the outer pivot with an outer wall of a pocket to occur near the pivot axis during rotation of the first coupling member and the locking member above a predetermined RPM thereby reducing overall moment on the locking member about the pivot axis that has to be overcome to move the locking member between the engaged and disengaged positions.
Abstract:
A coupling and control assembly includes a coupling subassembly and a control subassembly integrated with the coupling subassembly. The control subassembly has a reciprocating member and actuators operatively connected to the reciprocating movement for controlled reciprocating movement therewith to move or pivot respective struts received within pockets of a coupling member of the coupling subassembly. The reciprocating member converts a pressure of a working fluid at its working face to move linearly together with the actuators from its first position which corresponds to a first operating mode of the coupling subassembly to its second position which corresponds to a second operating mode of the coupling subassembly.
Abstract:
A coupling and control assembly includes first and second rotatable coupling members. The first coupling member has a first coupling face with locking formations, and the second coupling member has a second coupling face with pockets and in opposition with the first coupling face of the first coupling member and a third face spaced from the second coupling face and with passages communicating with the pockets. Locking members in the pockets transmit torque between the first and second coupling members. A stator includes an electromagnetic source, and a translator is translatable, rotatable, and coupled to the second coupling member to be rotatable therewith. The translator may include springs in the passages to actuate the plurality of locking members, or a permanent magnetic source cooperative with the electromagnetic source to translate the translator. An apertured retainer plate may be coupled to the second coupling member to facilitate pivoting of the plurality of locking members.

Abstract:
An electro-dynamic coupling and control assembly and a switchable linear actuator device are provided. The assembly has first and second coupling members each of which is supported for rotation about a common rotational axis and at least one locking member for selectively mechanically coupling the coupling members together. The device includes a stator structure including at least one electromagnetic source and a translator structure configured to be coupled to the second coupling member to rotate therewith. The translator structure includes at least one plunger which is elastically deformable in an axial direction to provide the device with compliance. Each plunger has a free end portion configured to move within a passage to engage and actuate a locking member within a pocket in the second coupling member.
Abstract:
An electromagnetic system for controlling the operating mode of a non-friction coupling assembly and a coupling and magnetic control assembly are provided. Magnetic circuit components include a ferromagnetic or magnetic element received within a pocket of a coupling member. The element controls the operating mode of the coupling assembly. A stationary electromagnetic source includes at least one excitation coil which generates a magnetic field between poles of the source when the at least one coil is supplied with current. Ferromagnetic or magnetic first and second inserts are received and retained within first and second spaced passages, respectively, of the coupling member. The electromagnetic source, the element, the inserts and air gaps between the various magnetic circuit components make up a closed loop path containing magnetic flux so that the element moves between first and second positions of the element when the at least one coil is supplied with current.
Abstract:
Overrunning coupling and control assembly and control system for use therein are provided. The system includes a control member mounted for controlled shifting movement between the coupling faces of first and second coupling members. An actuator arm includes an output member and a one-way locking member which is pivotally connected to output member which, in turn, is coupled to the control member. The locking member moves between a disengaged position in which the control member is permitted to shift or rotate relative to the second coupling member and an engaged position with a locking member-engaging portion of the second coupling member to lock the control member and the second coupling member together to prevent the control member from inadvertently shifting in a first direction relative to the second coupling member in the absence of an actuator command signal received by a bi-directional actuator assembly of the system.
Abstract:
A controllable or selectable coupling assembly having an overrun mode and a retained control element is provided. The assembly includes first and second coupling members having first and second coupling faces, respectively, in close-spaced opposition with one another. A locking member is disposed between the coupling faces of the coupling members. The locking member is movable between first and second positions. A control element is mounted for controlled movement between the coupling faces and is operable to control position of the locking member. The control element has at least one opening which extends completely therethrough to allow the locking member to extend therethrough. A retainer mechanism is operative to allow limited movement of the control element towards the first coupling face and prevent the control element from contacting the first coupling member in the overrun mode thereby reducing spin losses when the assembly is disengaged.
