Abstract
A gearbox attachment of a wheel drive unit A-shield assembly for an electric vehicle four motor powertrain system is disclosed. The gearbox attachment includes a housing, a gear reduction assembly, and an actuator assembly. The housing is adapted to fasten to an A-shield of the wheel drive unit A-shield assembly. The housing includes an outer ring. The gear reduction assembly is at least partially received in the outer ring. The gear reduction assembly is adapted to receive an output of a gearbox of the wheel drive unit A-shield assembly that is adapted to provide an output of a motor to a single wheel of the electric vehicle. The gear reduction assembly is adapted to provide a gear reduction for a higher torque and slower speed in a gear reduction mode. The actuator assembly adapted to actuate the gear reduction assembly output between the gear reduction mode and a standard mode.
