Abstract

An improved two-speed drive axis assembly (10) of the sliding clutch gear (60) type is provided. The interengageable clutch teeth (62A, 64A), utilized to engage the low speed mode of operation of the drive axle assembly are modified by utilizing a backlash one-and-six tenths (1.6) to two (2.0) times greater than the normally utilized backlash for providing smoother and quicker engagement of the low speed ratio and allowing utilization of a more compact lower force actuator (70) to reduce wear and tear on the interengageable low speed clutch teeth.
