Abstract
Two coaxial shafts having respective adjacent ends are joined together by a coupling assembly including a coupling sleeve which is rotatably supported within the interior of a third shaft concentrically disposed about the coaxial shafts. The adjacent ends of the coaxial shafts have external splines which are configured to be inserted into and engage internal splines formed in the bore of the coupling sleeve. The third shaft is rotatably supported by a housing in which the coupling assembly is positioned and may include an output sleeve portion. The coupling assembly is advantageously employed in the drive train of heavy vehicles in which the coaxial shafts form a part of the transmission input shaft and the third shaft forms a part of the transmission output shaft.
