  • Patent number: 4379413
    Abstract: A drive unit is disclosed having interlocking members for directly connecting angularly disposed drive and driven shafts. The interlocking members comprise conventional pinion mate and side gear blanks supported in a standard differential housing driven by a drive shaft through a ring and pinion gear set. Pinion mate gear blanks are connected by the usual cross shaft to the differential housing. Side gear blanks cooperate with the pinion mate gear blanks and are connected to the driven shaft. Integral locking surfaces provided on the mating gear blanks cooperate to prevent the side gear blanks from rotating relative to the differential housing so that a direct drive power path is established between the drive and driven shafts.
