Embodiment Construction

[0023] Refer to the attached figure 1 , an exemplary axle assembly constructed in accordance with the teachings of the present disclosure is indicated generally by the reference numeral 10 . In the particular example provided, the axle assembly 10 is a self-contained front axle assembly with disconnect capability, but it will be recognized that the teachings of the present disclosure apply to various other types of axle assemblies, and thus, herein The specific examples illustrated and described are not intended to limit the scope of the present disclosure in any way. The axle assembly 10 may include a housing assembly 12, an input pinion 14, a ring gear 16, a differential assembly 18, a first output member or half shaft 22, a second output member or half shaft 20, and clutches or couplings. Shaft device 24.

[0024] The housing assembly 12 may be configured to house the input pinion 14 , the ring gear 16 , the differential assembly 18 and the coupling 24 . The housing asse...

Abstract

A split axle assembly has a planetary differential assembly and a coupling that selectively couples a planetary carrier of the planetary differential assembly to the half shafts.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 62 / 287076, filed January 26, 2016, the disclosure of which is incorporated by reference as if set forth in full detail herein. technical field [0003] The present disclosure relates to a split axle assembly with a planetary differential. Background technique [0004] Modern vehicles with all-wheel-drive or four-wheel-drive drivetrains typically employ split axles to limit drivetrain operation so that only a single set of wheels is driven. Configuration in this manner provides the driveline with enhanced traction performance (i.e., when all four wheels are actively driven) and fuel economy approaching that of a conventional two-wheel drive driveline (i.e., when only two wheels are actively driven ). Examples of split axles are found in US 9199535 and US 9074672. While such disconnect drive trains are well suited for their intended purpose, there r...
