Abstract

An all-gear differential designed primarily for motor vehicle use, employing a “cross-axis” arrangement defined by a pair of helical “side” or “S” gears rotatable about a common first axis and mountable on respective opposite vehicle axles, and one or more pairs of “balance” or “B” gears rotatable about second axes orthogonal to the first axis. The B gears have helical central portions for meshing with the helical S gears, and have spur gear end portions for meshing with each other. The B/S helical gear tooth ratio between each balance gear and its respective side gear greater than 0.60 and preferably is about 0.75, and the B/S helical angle ratio between each balance gear and its respective side gear is less than 43°/47°, more preferably is less than 40°/50° and about 35°/55°, and most preferably is about 27°/63°.
