Abstract:

A combination starter-generator device is provided for a work vehicle having an engine. The starter-generator device includes an electric machine and a gear set configured to receive rotational input from the electric machine and the engine. The gear set includes a ring gear formed by a cylindrical base with a perimeter surface facing the engine and a circumferential row of castellations extending in a radial direction from the perimeter surface. The starter-generator device further includes a mounting arrangement comprising a drive plate configured to be secured to a crank shaft of the engine and a flex plate mounted to the drive plate. The flex plate includes a row of engagement apertures configured to receive the castellations of the ring gear to rotationally couple the ring gear to the engine via the mounting arrangement.
