ABSTRACT:
An improved differential mechanism of the holdout ring type is disclosed, characterized in that the annular holdout rings are mounted concentrically between the driven clutch members and the associated side gears, respectively, and the springs biasing the driven clutch members toward engagement with the driving spider member arranged therebetween includes a pair of compression springs mounted concentrically between the holdout rings and the side gears, each spring reacting at opposite ends between the associated side gear and annular spring retainer member, respectively. Furthermore, the driven clutch members are each provided with only one set of uniform teeth which cooperate both with driving teeth on the spider member and overrunning clutch-disengaging teeth on the center cam member. Consequently, a compact durable positive differential mechanism is provided that is of relatively simple, inexpensive construction requiring a minimum number of parts.
