Abstract
(EN)
In this electric drive module, a power conversion circuit (12) drives a motor (23-25). Coolant paths (13, 21) cause a refrigerant for cooling the motor and the power conversion circuit to circulate. A housing (40) integrally accommodates the motor and the power conversion circuit and comprises the coolant paths. An inlet (31) to the coolant paths for the refrigerant is provided so as to protrude from the housing. An outlet (32) from the coolant paths for the refrigerant is provided so as to protrude from the housing. A gear device (200) comprises: a speed-reducing unit (210) including a speed reducer connected to a rotating shaft (23) of the motor; and a differential unit (220) including a differential device connected to the output shaft of the speed reducer. The gear device (200) is fixed to the housing. The inlet and the outlet are provided to positions facing the gear device.

L'invention concerne un module d'entraînement électrique dans lequel un circuit de conversion de puissance (12) entraîne un moteur (23 à 25). Des trajets de liquide de refroidissement (13, 21) entraînent la circulation d'un liquide de refroidissement pour refroidir le moteur et le circuit de conversion de puissance. Un boîtier (40) loge intégralement le moteur et le circuit de conversion de puissance et comprend les trajets de liquide de refroidissement. Une entrée (31) vers les trajets de liquide de refroidissement pour le liquide de refroidissement est prévue de façon à faire saillie à partir du boîtier. Une sortie (32) des trajets de liquide de refroidissement pour le liquide de refroidissement est prévue de façon à faire saillie à partir du boîtier. Un dispositif à engrenage (200) comprend : une unité de réduction de vitesse (210) comprenant un réducteur de vitesse raccordé à un arbre rotatif (23) du moteur ; et une unité différentielle (220) comportant un dispositif différentiel raccordé à l'arbre de sortie du réducteur de vitesse. Le dispositif à engrenage (200) est fixé au boîtier. L'entrée et la sortie sont prévues à des positions faisant face au dispositif à engrenage.
