Abstract
A torque-proportioning differential of the helical pinion type includes a housing having a body section to one end of which is removably connected a cover section, the one body section end being machined to define a central longitudinal bore and a plurality of circumferentially spaced longitudinal pinion cavities each having a pair of cavity portions in longitudinal communication with each other and with the central bore, respectively. The pinion cavity portions are of equal depth, thereby to receive corresponding longitudinally offset helical pinions, 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.
