Abstract

Transmission d'un essieu d'entraînement comprenant deux demi-axes (HAR, HAL) coaxiaux entre eux et un groupe de deux réducteurs épicycloïdaux, dans laquelle chaque réducteur épicycloïdal a une première porte (SUR, SUL), raccordée de manière opérationnelle à un même arbre principal de transmission (MST), une deuxième porte (CGR, CGL) raccordée de manière opérationnelle à un demi-axe (HAR, HAL) relatif et une troisième porte (RR, RL) raccordée de manière opérationnelle à un même actionneur électrique (EA) ayant un rotor raccordé de sorte qu'une rotation relative est transmise à la troisième porte des deux réducteurs épicycloïdaux en sens inverse entre l'un par rapport à l'autre.Transmission of a drive axle comprising two half-axes (HAR, HAL) coaxial with each other and a group of two planetary gearboxes, in which each planetary gearbox has a first door (SUR, SUL), operatively connected to a same main transmission shaft (MST), a second door (CGR, CGL) operatively connected to a relative semi-axis (HAR, HAL) and a third door (RR, RL) operatively connected to the same electric actuator (EA) having a rotor connected so that a relative rotation is transmitted to the third door of the two planetary gearboxes in opposite direction with respect to one another.
