Systems and processes described herein can use drive line actuators (DLAs) which can be implemented for one or more individual wheels of an electric vehicle (EV) permitting connection and disconnection of at least a portion of the axle and wheel from the electric motor suppling torque. A disconnected wheel and axle can experience less friction, and have less rotational mass then a wheel and axle that is connected to an electric motor, therefore the disconnecting wheels in which torque is not desired can result in increased efficiency and range in an EV.

Methods and systems are provided for operating an electromagnetic pulse disconnect assembly for selectively engaging two rotating components of a vehicle drivetrain. A disconnect assembly is needed that is not powered by vacuum diverted from an engine of the vehicle, as modern engines are being developed to reduce vacuum production and remove vacuum lines for powering peripheral devices such as disconnects. An electromagnetic pulse disconnect assembly is provided that operates via pulses of electrical current and includes an electromagnetic coil for translating a clutch ring assembly and a latching ring assembly to selectively couple two rotating components.
F16D 19/00 - Clutches with mechanically-actuated clutching members not otherwise provided for
F16D 27/118 - Magnetically-actuated clutchesControl or electric circuits therefor with an electromagnet not rotating with a clutching member, i.e. without collecting rings with interengaging jaws or gear teeth
F16D 48/06 - Control by electric or electronic means, e.g. of fluid pressure
F16D 11/14 - Clutches in which the members have interengaging parts with clutching members movable only axially
F16D 11/00 - Clutches in which the members have interengaging parts
F16D 23/12 - Mechanical clutch-actuating mechanisms arranged outside the clutch as such
Methods and systems are provided for a motorized disconnect operable to selectively engage and disengage two rotating components of a vehicle drivetrain. As one example, a motorized disconnect system is provided that operates via an electric motor and includes a shifter assembly with an oscillating gear track and cam profile for rotating the shifter assembly while moving it in an axial direction to selectively couple two rotating components.
H02P 15/02 - Conjoint control of brakes and clutches
B60K 23/08 - Arrangement or mounting of control devices for vehicle transmissions, or parts thereof, not otherwise provided for for changing number of driven wheels
F16D 23/12 - Mechanical clutch-actuating mechanisms arranged outside the clutch as such
A wheel end of a vehicle includes a knuckle and a wheel and wheel hub rotatably mounted to the knuckle. A CV-joint is positioned adjacent to the wheel hub. A clutch ring is slidable between engagement with one of the wheel hub and the CV-joint or both. A pneumatic annular actuator is connected to a shift fork that is engaged with the clutch ring for movement of the clutch ring between engaged and dis-engaged. The shift fork includes a base portion and an L-shaped section. The L-shaped section includes a plurality of slots therein to allow the shift fork to deflect and pivot when a misalignment occurs between the teeth of the constant velocity joint half shaft and the clutch ring during assembly of the CV-joint to the wheel hub. The pneumatic actuator includes an elastomeric diaphragm wall that includes a compliant stop extending axially therefrom.
B60W 10/119 - Conjoint control of vehicle sub-units of different type or different function including control of all-wheel-driveline-means, e.g. transfer gears or clutches for dividing torque between front and rear axles
B60K 23/08 - Arrangement or mounting of control devices for vehicle transmissions, or parts thereof, not otherwise provided for for changing number of driven wheels
A pulse vacuum hub lock system for selectively engaging a wheel hub to an axial shaft includes a cartridge housing assembly received in a bore in the wheel hub. The cartridge housing assembly supports a clutch ring for movable engagement between splines in the wheel hub and directly on the axle shaft. A diaphragm is connected to a piston assembly and is responsive to a vacuum pressure to activate the piston assembly to engage or disengage a latch mechanism that holds the clutch ring in an engaged or disengaged position. A piston spring and a helper spring are provided between primary and secondary pistons of the piston assembly and allow for separation in the vacuum levels required to activate the latch mechanism. The vacuum hub lock system is compact so as to be disposed inboard of an opening in the exterior surface of a wheel rim.
F16D 25/04 - Fluid-actuated clutches in which the fluid actuates an elastic clutching member, e.g. a diaphragm or a pneumatic tube
B60K 17/35 - Arrangement or mounting of transmissions in vehicles for driving both front and rear wheels, e.g. four wheel drive vehicles having differential means for driving one set of wheels, e.g. the front, at one speed and the other set, e.g. the rear, at a different speeds including arrangements for suppressing or influencing the power transfer, e.g. viscous clutches
B60K 23/08 - Arrangement or mounting of control devices for vehicle transmissions, or parts thereof, not otherwise provided for for changing number of driven wheels
F16D 11/14 - Clutches in which the members have interengaging parts with clutching members movable only axially
F16D 11/00 - Clutches in which the members have interengaging parts

Four-wheel drive center disconnect electric actuator
A four-wheel drive center disconnect electric actuator is provided. The actuator includes a one-way motor that actuates a cam mechanism for causing engagement and disengagement of the center disconnect. The actuator achieves improved reliability and efficiency through a less expensive construction than conventional actuators.
