Abstract

A pinion shaft of an axle drive bevel pinion mating with a bevel gear is disposed in two tapered roller bearings, the joint outer race of which is flanged onto the axle housing. In order to lubricate the tapered roller bearings with splash oil and avoid dirt deposits in the bearing area, the outer race of the tapered roller bearings has an oil feeding duct to a collecting pipe arranged above, and at its underside, an oil return duct to the transmission oil sump.
