Embodiment Construction

[0024] see attached figure 1 , an exemplary vehicle 10 is illustrated including a powertrain 12 and a driveline 14 . The powertrain 12 may include a prime mover 20 and a transmission 22 . Prime mover 20 may be an internal combustion engine or an electric motor, and may be configured to provide rotational power to transmission 22 . The transmission 22 may be any type of transmission, such as a manual transmission, an automatic transmission, or a continuously variable transmission, and may be configured to provide rotational power to the driveline 14 .

[0025] The driveline 14 may include a transfer case 32 , a rear propshaft 34 , a rear axle assembly 36 , a front propshaft 38 and a front axle assembly 40 . Transfer case 32 may receive rotational power from transmission 22 . Rear prop shaft 34 may be drivingly coupled to rear output 42 of transfer case 32 and may transmit rotational power to rear axle assembly 36 . The rear axle assembly 36 may be configured to transmit rot...

Abstract

A compact axle assembly with a locking differential assembly is provided. The axle assembly has a carrier housing, a locking differential assembly, a pair of differential bearings and an actuator assembly. The carrier housing includes a cavity. The locking differential assembly includes a differential case received in the cavity. The differential case includes a bearing bore in which an outer race of the differential bearing is received. The actuator assembly includes a sleeve movable between a first sleeve position and a second sleeve position, the first sleeve position being configured to operate the locking differential assembly in an unlocked mode, and The second sleeve position is configured to operate the locking differential assembly in a locked mode. When the sleeve is in the first sleeve position and / or the second sleeve position, the sleeve is at least partially radially aligned with the differential bearing so as to be perpendicular to the axis The plane taken extends through both the sleeve and the differential bearing.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 983092, filed April 23, 2014, the disclosure of which is hereby incorporated by reference as if fully set forth. technical field [0003] The present invention relates to a compact axle assembly with a locking differential assembly. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] In the off-road field, beam axle assemblies are believed to offer advantages over other axle assembly types when operating in certain types of terrain, such as when climbing rocks. These advantages include increased durability perception, and engagement of the axle assembly when traversing uneven terrain so that the position of the differential can be varied as a function of the position of the axle wheels to better avoid ground / obstacles from contacting the axle ass...
