Abstract:
A disconnect assembly for translating torque to shafts of a driveline. A clutch is disposed in torque translating relationship between the shafts and is movable between an engaged configuration wherein torque is translated, and a disengaged configuration wherein torque is interrupted. An actuator includes a coil that generates a first magnetic field. A slider is movable between a first stable position and a second stable position, with an armature operatively attached to the slider. The armature has a magnetic polarity pattern defined by a plurality of north and south magnetic pole regions facing the coil. The pattern configured such that predetermined changes in the magnetic field generated by the coil urge the slider from one of the stable positions to the other of the stable positions so as to cause corresponding movement of the clutch assembly between the configurations to selectively translate rotational torque between the shafts of the driveline.
Abstract:
A number of variations may include a product that may include an axle assembly with an electrical machine that may be interconnected with the axle assembly. A power transfer unit may be connected between the electrical machine and the axle assembly. The power transfer unit may include a planetary gear set and may include an engagement mechanism that in combination may provide a low range, a neutral mode and a high range between the electrical machine and the axle assembly. A first gear set may be engaged between the electrical machine and the power transfer unit and a second gear set may be engaged between the power transfer unit and the axle assembly.
Abstract:
An electric drive unit for a powertrain system including first and second drivelines and a primary propulsion system for translating rotational torque to the first driveline. A motor acts to generate rotational torque and a pinion is disposed in selective communication therewith. A differential is interposed between the pinion and the second driveline of for splitting torque therebetween. A first planetary is disposed between the motor and pinion, and a second planetary is disposed between the first planetary and pinion. A dog clutch interposed between the pinion and the planetaries is movable between a first position wherein torque from the motor is translated through the first planetary and the dog clutch to drive the second driveline at a first drive ratio, and a second position wherein torque from the motor is translated through both planetaries and the dog clutch to drive the second driveline at a second drive ratio.
Abstract:
A product may include a differential unit that may be engaged with first and second axle shafts that may be driven from a common gear. An electrical machine may be positioned on a first side of the differential unit. A first shaft may extend from the electrical machine and into the differential unit. A power transfer unit may be positioned on a second side of the differential unit opposite the first side. A second shaft may extend into each of the differential unit and the power transfer unit. The first and second shafts may be rotationally engageable through the power transfer unit.
Abstract:
A product may comprise an electric machine, and may include first and second shafts connectable to the electric machine in torque a transferring relationship. A first clutch assembly may selectively connect the electric machine with the first shaft and a second clutch assembly may selectively connect the electric machine with the second shaft. A gear set may be operatively engageable between the electric machine and the first and second clutch assemblies. An engagement coupling may connect the gear set in a high range between the electric machine and the first and second clutch assemblies, and the engagement coupling may connect the gear set in a low range between electric machine and the first and second clutch assemblies.
