Drivetrain for a ground vehicle

摘要

A drivetrain providing tractive torque to a ground vehicle includes a non-combustion torque machine coaxial to and rotatably coupled to an integrated gear set including a conjoined carrier assembly coupling a reducing gear set to a differential gear set. The differential gear set is coaxial to and rotatably coupled to first and second differential axle members. The first differential axle member couples to a first wheel assembly of the ground vehicle and the second differential axle member couples to a second wheel assembly located on a second, opposite side of the ground vehicle.

1. A drivetrain providing tractive torque to first and second wheel assemblies of a ground vehicle that includes an internal combustion engine including an oil pan, the drivetrain comprising a non-combustion torque machine coaxial to and rotatably coupled to an integrated gear set including a conjoined carrier assembly coupling a reducing gear set to a differential gear set, wherein the non-combustion torque machine includes a rotor member and a housing, said differential gear set being coaxial to and rotatably coupled to first and second differential axle members, said first differential axle member coupled to the first wheel assembly arranged on a first side of the ground vehicle and said second differential axle member coupled to the second wheel assembly arranged on a second, opposite side of the ground vehicle;
wherein the rotor member of the non-combustion torque machine is coupled to a tubular motor member coupled to an intermediate member rotatably coupled to a rotatable element of the integrated gear set; wherein the tubular motor member, the intermediate member and the rotatable element of the integrated gear set are concentric to the first differential axle member coupled to the first wheel assembly; wherein the intermediate member and the first differential axle member pass through a cylindrically-shaped hollow tube fabricated to pass from a first side to a second side of the oil pan; and wherein an inboard portion of the housing for the non-combustion torque machine is fabricated onto the first side of the oil pan.
