SELF-CONTAINED ELECTRIC AXLE FOR ALL-WHEEL DRIVE

摘要

A driveline (12) of a motor vehicle having an internal combustion engine (10) for propelling the vehicle and method of assembly can include a self-contained drive axle assembly (35). The self-contained drive axle assembly (35) can include an electric motor (18) for propelling the motor vehicle mounted coaxial with and sheathing a first portion of the drive axle assembly (35) and a disconnect clutch (20) mounted coaxial with and sheathing a second portion of the drive axle assembly (35) for selectively connecting powered rotation between the electric motor (18) and a gear box (14). The drive axle assembly (35) can include the gear box (14) having at least one of a transmission (15) and a power take off unit (40) mounted coaxial with and sheathing a third portion of the drive axle assembly (35) for transferring powered rotation to a pair of wheels (16a, 16b) through the drive axle assembly (35).

1. In a motor vehicle having an internal combustion engine (10) for propelling the motor vehicle while dissipating waste energy during operation and a driveline (12) for transferring torque between at least one pair of wheels (16a, 16b), the improvement of the driveline (12) comprising:
a self-contained drive axle assembly (35) including:
an electric motor (18) for propelling the motor vehicle mounted coaxial with and sheathing a first portion of the drive axle assembly (35);a disconnect clutch (20) mounted coaxial with and sheathing a second portion of the drive axle assembly (35) for selectively connecting powered rotation of the electric motor (18); anda gear box (14) connected to the disconnect clutch (20) and including at least one of a transmission (15) and a power take off unit (40) mounted coaxial with and sheathing a third portion of the drive axle assembly (35) for transferring powered rotation to the at least one pair of wheels (16a, 16b) through the drive axle assembly (35).
