ABSTRACT:
A power transmission unit comprises a trans-axle casing provided therein with an upright partition wall for subdividing the interior of the casing into front and rear chambers and having a cover plate for closing in a fluid tight manner the forward open end of the front chamber, a differential gear unit arranged within the front chamber and having a pair of side-journals rotatably supported by a pair of spaced bearings carried on a pair of carrier portions of the casing, and a crown wheel integral with the differential gear unit and in mesh with a drive pinion of a final drive gearing to drive the differential gear unit. The cover plate is provided at its inner wall integral with a pair of lateral protrusions or ribs extending downwardly from an upper portion of the cover plate toward each side-journal of the differential gear unit at both sides of the crown wheel to receive lubricating oil flowing around the crown wheel and induct it to bearing portions of the side-journals.
