ABSTRACT:
An improved non-slip differential (10) includes a case (12) with a rotatable control shaft (52) and sliding control bushings (80) supporting a pair of offset bevel gears (50) which are coupled via U-joints (62) to output shafts (48). A pinion gear (64b) is set at an obtuse angle between the bevel gears (50) such that neither bevel gear and corresponding output shaft (48) can be driven to the exclusion of the other. Another pinion gear (64a) set at an acute angle relative to the bevel gears (50) is preferably included for additional load distribution between the bevel gears. A second embodiment (80) incorporates non-toothed bevels (82) and pinions (84a and 84b) in frictional engagement.
