In a differential drive having one differential carrier rotating in a housing, two side shaft gears are arranged coaxially relative to said differential carrier, and two sets of differential gears are supported in the differential carrier and rotate therewith and each engage one of the side shaft gears. The side shaft gears are crown gears and the differential gears form two sets of straight pinions which rotate on radial journals in the differential carrier, with the pinions of the two sets directly engaging one another in pairs so that, when the differential carrier is stationary, the side shaft gears are able to rotate in identical directions. In a differential drive having two differential carriers rotating in a housing, two side shaft gears are arranged coaxially relative to said differential carriers, and two sets of differential gears are supported in the differential carriers and rotate therewith, and each engage one of the side shaft gears. The side shaft gears are hollow gears and the differential gears form two sets of straight pinions serving as planetary gears, which rotate on axis-parallel journals in the differential carriers and engage one single, central, freely-rotatable pinion acting as a sun gear, so that, when the differential carriers are stationary, the side shaft gears are able to rotate in identical directions.
A differential drive (41) having two differential carriers (43, 44) rotating in a housing (42), two side shaft gears (50, 51) arranged coaxially relative to said differential carriers (43, 44), and two sets of differential gears (54, 55) which are supported in the differential carriers (43, 44) and rotate therewith and which each engage one of the side shaft gears (50, 51), wherein said side shaft gears (50, 51) are hollow gears and said differential gears (54, 45) form two sets of straight pinions serving as planetary gears, which rotate on axis-parallel journals (56, 57) in said differential carriers (43, 44) and engage one single, central, freely-rotatable pinion (64) acting as a sun gear, so that, when said differential carriers (43, 44) are stationary, said side shaft gears (50, 51) are able to rotate in identical directions.
