Patent number: 9784321Abstract: A wheel-end disconnect assembly for translating rotational torque between an output shaft and a wheel hub of a vehicle driveline. A knuckle bracket at least partially supports the wheel hub. A clutch is operatively attached to the knuckle bracket, is disposed in selective torque translating relationship between the output shaft and the wheel hub, and is movable between: an engaged configuration wherein torque is translated between the output shaft and the wheel hub, and a disengaged configuration wherein torque is interrupted. An electromagnetic actuator is provided and has a slider selectively movable between a first stable position and a second stable position. The actuator is disposed in force translating relationship with the clutch such that movement from one stable position to the other stable position causes corresponding movement of the clutch between the configurations so as to selectively translate rotational torque between the output shaft and the wheel hub.Type: GrantFiled: February 26, 2016Date of Patent: October 10, 2017Assignee: BorgWarner Inc.Inventor: Larry A.

The sprocket (12) receives rotational drive input from an engine crankshaft. One or more of the three ring gear(s) (26, 28, 30) receives rotational drive input from the sprocket (12) and rotates with the sprocket (12), and the remaining ring gear(s) (26, 28, 30) transmit rotational drive output to an engine camshaft (62). All three of the ring gears (26, 28, 30) engage with the planet gears (24). And the sun gear (22) also engages with the planet gears (24).
