Abstract
A modular drive axle having left and right drive wheels and axles that are coupled to a differential. The left and right axles are in line and define a transverse axis. A bevel gear assembly having first and second bevel gears mounted on a drive shaft directs rotary motion from a transmission to the differential for driving the drive wheels. The bevel gear assembly drive shaft is perpendicular to the transverse axis and the transmission which is operatively coupled to the bevel gear assembly and arranged parallel to the transverse axis. The transmission is a collar shift transmission having an input collar with two output surfaces. The first output surface of the input collar drives a fixed countershaft gear having first and second output surfaces. The first and second output surfaces drive first and second intermediate gears. A gear selector collar is slidably positioned on a drive shaft and selectively engages either the first intermediate gear, the second intermediate gear, or the second output surface of the input collar. The selector collar is provided with bi-directional self centering surfaces.
