TITLE DIFFERENTIAL MECHANISM 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 receptionof 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 gearor 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 ringgear and trunnion bearings hold the half-casings together as a closed unit and the snap ring holds the journal pin in the casing. |
