Abstract
A shaft oil flow controller arrangement for pinion shaft bearings in a differential is provided, including a housing along with a pinion shaft supported therein by head and tail bearings. A ring gear is mounted for rotation and is engaged with a pinion gear. A bearing spacer is located on the pinion shaft between the head and tail bearings. A diverter is located on the bearing spacer, and includes a circumferentially extending diverter wall that is moveable from a first position in which the wall extends generally in a longitudinal direction of the pinion shaft at a first, lower rotational speed of the pinion shaft allowing a first volume of lubricant oil flow to the head bearing, to a second position, in which the wall extends radially outwardly at a second, higher rotational speed, to restrict lubricant oil flow to the head bearing to a lower volume, and increase oil flow to the tail bearing.
