Abstract
A differential gear is to be interposed between an input shaft and first and second output shafts in an automotive vehicle. The differential gear includes a carrier rotatable together with the input shaft, a pair of first and second pinions disposed on one side of the carrier and rotatably supported on the carrier, a pair of third and fourth pinions disposed on the other side of the carrier and rotatably supported on the carrier, a first internal gear rotatable together with the first output shaft and having common rotational axis with the carrier, and a second internal gear rotatable together with the second output shaft and having a common rotational axis with the carrier. The first and second pinions are placed symmetrically with respect to the rotational axis of the carrier. Likewise, the third and fourth pinions are placed symmetrically with respect to the rotational axis of the carrier. The first and second internal gears are in mesh with the first and second pinions and the third and fourth pinions, respectively. On each side of the carrier, the set of one internal gear and two pinions constitutes two gear pumps.
