ABSTRACT:
A parallel-axis gear differential includes one or more pairs of planet gears (68 and 70) for interconnecting two side gears (34 and 36). The planet gears (68 and 70) include at least three meshing portions (82, 84, and 88 and 94, 96, and 98). One of the meshing portions (82 or 96) of each planet gear (68 or 70) engages one of the side gears (34 or 36), and the other two meshing portions (84 and 88) of one planet gear (68) engage respective meshing portions (94 and 98) of its paired planet gear (70). The two planet-to-planet meshes (84/94 and 88/98) straddle one of the side gears (36), and the two side gears (34 and 36) straddle one of the planet-to-planet gear meshes (84/94). A spacer block (46) is positioned between the side gears (34 and 36 ).
