Abstract
A differential assembly arrangement with optimized pinion shaft bearing lubrication is provided. The assembly includes a housing, a ring gear, a pinion gear, a pinion shaft supported by two rolling element bearings, a sleeve, and a lubrication deflector. The two rolling element bearings, a pinion head bearing bearing and a pinion tail bearing, are located at each end of the sleeve which fits over the pinion shaft. The sleeve helps facilitate the application of a pre-load to the bearings. The lubrication deflector is located along the length of the sleeve for providing the correct amount of lubricant to the two bearings. The deflector is in the form of a ring located on the sleeve or integrated within the sleeve.
