Zusammenfassung:	A drive train for a four wheel drive vehicle including a front differential engaged with a front drive shaft and front axles through a front differential gear set. The front differential includes a front bi-directional overrunning clutch that controls transmission of torque transfer between the front drive shaft and the front axles. A rear differential is engaged with rear axles and the transmission through a rear differential gear set. The rear differential includes a rear bi-directional overrunning clutch that controls torque transfer between the transmission and the rear axles. The differentials are configured with a gear ratio that is within five percent of a 1 :1 gear ratio. L'invention concerne une transmission de véhicule à quatre roues motrices qui comprend un différentiel avant engrené avec une arbre de transmission avant et des essieux avant au moyen d'un jeu d'engrenages différentiels avant. Le différentiel avant comprend une roue libre bidirectionnelle avant qui commande la transmission du transfert de couple entre l'arbre de transmission avant et les essieux avant. Un différentiel arrière est engrené des essieux arrière et la transmission au moyen d'un jeu d'engrenages différentiels arrière. Le différentiel arrière comprend une roue libre bidirectionnelle arrière qui commande le transfert de couple entre la transmission et les essieux arrière. Les différentiels sont configurés avec un rapport d'engrenage qui est dans les limites de cinq pour cent d'un rapport d'engrenage 1:1.
