Abstract
A controllable one-way clutch assembly having an actuator module equipped with a solenoid actuator, an active strut moveable in response to energization of the solenoid actuator from a released position to a locked position, a strut spring biasing the active strut toward its released position, and an indirect strut actuation arrangement between the solenoid actuator and the active strut. The indirect strut actuation arrangement includes an intermediate actuation component having a first lug establishing a coupling interface with a translatable plunger of the solenoid actuator and a second lug establishing an engagement interface with the active strut.
Claims19
A one-way coupling device, comprising:
- a clutch module including a first clutch component, and a second clutch component arranged for rotation relative to the first clutch component and having ratchet teeth;
- and
- an actuator module mounted to the first clutch component and including a solenoid actuator with a plunger moveable between first and second positions, a strut moveable between a non-deployed position disengaged from latched engagement with the ratchet teeth and a deployed position in latched engagement with the ratchet teeth, a strut biasing member for normally biasing the strut toward its non-deployed position, and an indirect strut actuation arrangement having an actuation component moveable between non-actuated and actuated positions, the actuation component defining a coupling interface with the plunger and an engagement interface with the strut;
- wherein movement of the plunger from its first position to its second position in response to actuation of the solenoid actuator causes the actuation component to move from its non-actuated position into its actuated position which concomitantly causes the strut to move from its non-deployed position into its deployed position;
- wherein the strut is mounted in a strut pocket formed in the first clutch component for pivotal movement about a strut pivot axis, wherein the actuation component is mounted in an actuation pocket formed in the first clutch component for pivotal movement about an actuation pivot axis, and wherein the strut pivot axis is aligned to be generally orthoganal to the actuation pivot axis.

A one-way coupling device, comprising:
- a clutch module having a first clutch component, and a second clutch component arranged for rotation relative to the first clutch component and having ratchet teeth;
- and
- an actuator module mounted to the first clutch component and including a solenoid actuator with a plunger moveable between first and second positions, a strut moveable between a non-deployed position disengaged from the ratchet teeth and a deployed position engaged with the ratchet teeth, a strut biasing member for biasing the strut toward its non-deployed position, and an indirect strut actuation arrangement having an actuation component moveable between non-actuated and actuated positions, the actuation component defining a coupling interface with the plunger and an engagement interface with the strut,
- wherein the actuation component is mounted to the first clutch component for pivotal movement about an actuation pivot axis and includes a forked lug segment coupled to the plunger to define the coupling interface and an actuation lug segment having a tip portion engaging an engagement surface on the strut to define the engagement interface, wherein movement of the plunger from its first position to its second position in response to actuation of the solenoid actuator causes the forked lug segment to pivot the actuation component about its actuation pivot axis from its non-actuated position into its actuated position which concomitantly causes the actuation lug segment to drive the strut from its non-deployed position into its deployed position in opposition to the biasing of the strut biasing member.

A one-way coupling device, comprising:
- a clutch module including an outer clutch component, and an inner clutch component arranged coaxially for rotation relative to the outer clutch component and having an outer surface formed with ratchet teeth;
- and
- an actuator module mounted to the outer clutch component and including a solenoid actuator having a plunger moveable between first and second positions, a strut moveable between a non-deployed position disengaged from the ratchet teeth and a deployed position engaged with the ratchet teeth, and an indirect strut actuation arrangement disposed between the plunger and the strut and having an actuation component moveable between a non-actuated position and an actuated position, the actuation component defining a coupling interface with the plunger and an engagement interface with the strut such that movement of the plunger from its first position to its second position in response to actuation of the solenoid actuator causes movement of the actuation component from its non-actuated position to its actuated position which causes movement of the strut from its non-deployed position to its deployed position,
- wherein the outer clutch component includes a lateral side surface defining a strut pocket for supporting the strut for pivotal movement between its first and second positions about a strut pivot axis, and an actuation pocket for supporting the actuation component for pivotal movement between its non-actuated and actuated positions about an actuation pivot axis, wherein a mounting bracket is fixed to the lateral side surface of the outer clutch component and is configured to retain the strut within the strut pocket and retain the actuation component within the actuation pocket, and wherein the solenoid actuator is secured to the mounting bracket such that the plunger is connected via the coupling interface of the actuation component and is arranged to move between its first and second positions along a line of translational travel that is generally parallel to the strut pivot axis.
