  • Differential device for vehicles
    Patent number: 4125026
    Abstract: The present invention relates to a differential device for vehicles in which the differential casing is split into two casing portions including a left casing portion through which the left axle shaft runs and a right casing portion through which the right axle shaft runs, the two casing portions and the ring gear being joined together by electron beam welding after various devices are assembled into the differential casing, whereby assembly of various devices in the differential casing is facilitated; the differential casing and the ring gear being lightened by removal of redundant mass; the pinion shaft support in the differential casing being strengthened; and the pinion shaft being integrally fixed to the differential casing, thereby spreading the load and preventing slippage out of the pinion shaft.
