Title (EN) TORQUE DISTRIBUTING DRIVE MECHANISM WITH LIMITED SLIP
(FR) MECANISME D'ENTRAINEMENT DE DISTRIBUTION DE COUPLE A GLISSEMENT LIMITE
Abstract:
(EN) A drive axle assembly includes first and second axleshafts and a drive mechanism coupling a driven input shaft to the axleshafts. The drive mechanism includes a differential assembly, a planetary gear assembly operably disposed between the differential assembly and the first axleshaft, a brake and first and second mode clutches. The first clutch is operable with the brake and the planetary gear assembly to increase the rotary speed of the first axleshaft which, in turn, causes a corresponding decrease in the rotary speed of the second axleshaft. The second clutch is operable with the brakes and the planetary gear assembly to decrease the rotary speed of the first axleshaft so as to cause an increase in the rotary speed of the second axleshaft. A control system controls actuation of both mode clutches.
(FR) La présente invention a trait à un ensemble d'essieu moteur comportant des premier et deuxième arbres de roue motrice et un mécanisme d'entraînement reliant un arbre primaire entraîné aux arbres de roue motrice. Le mécanisme d'entraînement comporte un ensemble différentiel, un ensemble de train planétaire disposé en fonctionnement entre l'ensemble différentiel et le premier arbre de roue motrice, un frein et des premier et deuxième embrayages de mode. Le premier embrayage est opérable avec le frein et l'ensemble de train planétaire pour accroître la vitesse de rotation du premier arbre de roue motrice qui, à son tour, entraîne une réduction correspondante dans la vitesse de rotation du deuxième arbre de roue motrice. Le deuxième embrayage est opérable avec les freins et l'ensemble de train planétaire pour réduire la vitesse de rotation du premier arbre de roue motrice afin d'accroître la vitesse de rotation du deuxième arbre de roue motrice. Un système de commande assure la commande de l'actionnement des deux d'embrayage de mode.
