Abstract
A differential drive having a drive housing in which a drivable differential carrier is rotatably supported and which comprises straight-toothed and helically toothed output gears connected to each other via differential gears which are axis-parallel thereto and of which a first group engages the one output gear and a second group the other output gear, with each of the differential gears of the one group engaging at least one of the differential gears of the outer group and with the differential gears, with their tooth heads, being held in partially cylindrical apertures of the differential carrier, with the axial length of at least some of said apertures being greater than the toothed region of the group of differential gears held therein, and with the apertures whose axial length is greater than that of the toothed region of the differential gears containing disc-shaped stop elements which extend radially inwardly beyond the inner cross-section of the apertures and which are axially supported on at least one of the output gears.
