Abstract:
An apparatus for supporting an electric power source in a transmission includes a transmission housing, and an electric machine including a rotor and a stator secured to the housing. A first member is secured to the rotor, extends radially toward an axis of rotation, and is formed with a first pilot surface. A second member, secured to the rotor and the housing, extends from the housing toward the axis and is formed with a second pilot surface that is aligned axially with the first pilot surface. An anti-friction bearing, located at an axial rearward side or axially frontward side of a torque converter, is engaged with the first pilot surface and the second pilot surface. A second balanced bearing is located either in the driving engine or the driven transmission.
