Zusammenfassung:	A suspended drive axle (26) and agricultural tractor (10) having same including a central housing having inboard final drives (52) and left and right axle housing (62) suspended therefrom by upper and lower control arms (64, 66) with axle shafts (44, 46) extending outwardly therefrom to which wheel and tire assemblies (14, 16) are mounted. A constant velocity universal joint (150) is provided between the inboard final drives (52) and the axle shafts (44, 46). The universal joint (150) having a pair of journal members (210, 212) and a coupling yoke (222) that radially surround the drive and driven yokes (174, 190) of the joint (150) whereby the axial length of the universal joint (150) is minimized to enable the wheels (14, 16) to be located on the axle shafts (44, 46) at 60 inch tread spacing. This allows the drive axle (26) to be used on a row crop tractor without altering the structure of the vehicle from a conventional row crop tractor whereby the characteristics of a row crop tractor are maintained. L'invention concerne un arbre d'entraînement suspendu (26), ainsi qu'un tracteur agricole (10) équipé d'un tel arbre, comprenant un carter central ayant des essieux moteurs intérieurs (52) et une boîte d'essieu droite et gauche (62) suspendue par des bras de commande supérieur et inférieur (64, 66) munis de corps d'essieu (44, 46) s'étendant vers l'extérieur et sur lesquels sont montés les ensembles de roues et pneus. Un joint de cardan (150) à vitesse constante est prévu entre les essieux moteurs intérieurs (52) et les corps d'essieux (44, 46). Le joint de cardan (150) présente une paire de tourillons (210, 212) et un étrier d'accouplement (222) entourant radialement les étriers menants et menés (174, 190) du joint, grâce à quoi la longueur axiale du joint à cardan (150) est minimisée, permettant ainsi aux roues (14, 16) d'être mises en place sur les corps d'essieu (44, 46) avec un espacement de la bande de roulement de 60 inch. Ceci permet d'utiliser l'arbre d'entraînement (26) sur un tracteur à voie large, sans pour autant modifier la structure d'un tracteur à voie large conventionnel et tout en conservant les caractéristiques d'un tel tracteur à voie large.
