AIR PISTON DIFFERENTIAL LOCKOUT Abstract of the Disclosure An axle assembly comprising a differential having a housing, an input drive pinion rotatably mounted in the housing and in driving meshing engagement with a drive gear rotatably mounted in the housing, the drive gear carrying a differential spider having rotatably thereon four differential pinions, a differential casing attached to the drive gear enclosing the differential spider and the differential pinions, a differential side gear also enclosed within the differential casing and in meshing engagement with the differential pinions, the internal bore of which is splined to accept an axle shaft through an opening in the differential casing, a cylindrical piston surrounding the axle shaft and splined thereto, the differential casing having a splined extension thereon to receive a comparably splined portion on the piston, biasing means biasing the piston along the longitudinal axis of the axle shaft to disengage the piston from the differential casing at their mating splined areas, a cylindrical cylinder surrounding the piston to provide an airtight chamber for compressed air acting on the piston within the airtight chamber to drive the piston in splined engagement with the splined portion of the differential casing to bypass and lockout the differential action of the differential pinions on the spider.
