Improved differential with equal depth pinion cavities

摘要

A torque-proportioning differential of the helical pinion type includes a housing 102 having a body section 102d to one end of which is removably connected a cover section 102b, the one body section end being machined to define a central longitudinal bore 106 and a plurality of circumferentially spaced pairs of longitudinal pinion cavities 108, 110 in longitudinal communication with each other and with the central bore, respectively. The pinion cavities of each pair are of equal depth, thereby to receive corresponding longitudinal offset helical pinions, 124, 126 respectively, each provided with a hub extension that extends longitudinally of the associated pinion bore for engagement with a corresponding end thrust surface on the housing body section or the housing cover section respectively.
