ABSTRACT:
A casing for and comprising an operative part of a differential mechanism for a vehicle drive. The casing consists of two identical halves, each half having walls defining a central, generally semi-annular space for differential pinions and gears, the walls being generated around the center line of the vehicle half-axles. Each half-casing also includes oppositely extending, tubular trunnion halves that also are semi-annular in shape and lie circumjacent the inner ends of the vehicle half-axles when the unit is assembled. There is a radial aperture at the pole of each half-casing in the central portion thereof for the reception of an end of a radially extending journal pin for the differential pinions. Each half-casing has a semi-circular flange of diameter larger than the central portion of the casing half. When the two half-casings are assembled, a ring gear or crown wheel fits circumjacently to the central portions of the half-casings against and is secured to the flanges. Trunnion bearings fit over the trunnion halves. A "C" shaped ring snaps over the central casing portions and engages the ends of the journal pin which protrude through the polar apertures. The ring gear and trunnion bearings hold the half-casings together as a closed unit and the snap ring holds the journal pin in the casing.
