摘要： 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.

摘要： A gear synchronizer assembly includes a clutch sleeve formed at its inner periphery with an internal radial projection, and a radially contractible annular resilient member supported by engagement with the inner circumference of an outer cylindrical hub portion of a hub member fixed to a transmission shaft. The resilient member has an axial leg extending therefrom toward the internal radial projection of the clutch sleeve and having a radial projection which is arranged to be engaged with the internal radial projection in shifting operation of the clutch sleeve toward a spline piece and arranged to abut against and urge a synchronizer ring toward the spline piece upon engagement with the internal radial projection of the clutch sleeve thereby to effect frictional engagement between the synchronizer ring and spline piece. The annular resilient member is further formed with at least one retainer lug which extends therefrom in an axial direction toward an annular body portion of the hub member and inserted into an axial hole in the annular body portion of the hub member to retain the resilient member in place in a circumferential direction.
