Abstract

A differential transmission for a motor vehicle comprising a driving gear wherein the driver gear introduces torque to the transmission; a first output element and a second output element wherein the first and second output elements output torque from the transmission; a differential cage designed for transmitting torque from the driving gear to the first output element, wherein the differential cage is non-rotatably connected to the driving gear, and the first output element is rotationally arranged to the differential cage; a sliding sleeve wherein the sliding sleeve is arranged between the differential cage and the first output element, wherein the sliding sleeve has a lubricating recess which extends in a spiral shape in the circumferential direction and is operatively arranged to provide a lubricating film.
