SELECTABLE CLUTCH MODULE ACTUATOR USING A SINGLE HYDRAULIC FEED TO ACHIEVE THREE OR MORE MODES
The actuating mechanism for the selectable clutch module may include an actuator housing that defines an actuator chamber. At least one piston may be disposed within the actuator chamber and configured to move between at least a first piston position and a second piston position. An armature may be attached to the piston and a cam may be operatively associated with the armature. The actuating mechanism may further include an actuator spring disposed within the actuator chamber and positioned between the piston and an end of the actuator housing. A hydraulic pressure may be supplied to the actuating mechanism to move the piston between the at least first piston position and the second piston position.
POSITION FORCE CONTROLLED ACTUATOR
An actuator device for a selectable clutch having three or more clutch modes may include a dual rate piston with a stable middle position. A positive stop provides very accurate control when shifting from an end position to a middle position without overshoot. Precision position control of the actuator device facilitates consistent, stable control of the current mode of the selectable clutch.
FOUR-MODE ROCKER CLUTCH
A four-mode rocker clutch, including: a clutch gear supported for rotation around an axis of rotation; a housing; a first pawl including a portion disposed within the housing; a first actuator; a second pawl including a portion disposed within the housing; and a first resilient element. For a first one-way mode of the four-mode rocker clutch: the first actuator is arranged to hold the first pawl in contact with the clutch gear; the first pawl is arranged to block rotation of the clutch gear, with respect to the housing, in a first circumferential direction around an axis of rotation; and the first resilient element is arranged to hold the second pawl out of contact with the clutch gear.
Electromagnetic actuator for wheel-end disconnect
A wheel end disconnect system includes an inner race connected to one of an axle half shaft and a wheel hub, an outer race connected to the other of the axle half shaft and the wheel hub, and a plurality of radially actuatable pawls, circumferentially spaced apart, oriented between the inner and outer races, and movable between an outboard locked position and an inboard unlocked position to connect and disconnect the wheel hub from the axle half shaft. The system further includes a plurality of pins attached to an actuator ring. The actuator ring is axially shift-able between a locked and unlocked position. The system also includes one or more permanent magnets forming a permanent magnet ring attached to the actuator ring, with axially spaced apart north and south poles, and an annular tri-pole electromagnet having two counter-wound axially spaced apart coils concentric with the annular permanent magnet.

Selectable one-way clutch with common coil unit and axially moveable armature for active strut actuation
A bi-directional clutch assembly includes an outer race defining first and second strut pockets, an inner race defining ratchet teeth, a passive one-way clutch including at least two passive struts each supported in a corresponding first strut pocket for pivotal movement relative to the ratchet teeth, passive strut springs for normally biasing the passive struts into engagement with the ratchet teeth on the inner race, and a selectable one-way clutch having at least one active strut supported in the second strut pocket for pivotal movement between a non-deployed position disengaged from the ratchet teeth and a deployed position engaged with the ratchet teeth, and an armature ring fixed for rotation with the outer race and axially moveable between a non-actuated position and an actuated position, in which a strut engagement feature moves the active strut from its non-deployed position to its deployed position.
