Title (EN) POWER TRAIN HAVING A GEARBOX WITH TEMPERATURE CONTROL BY COOLANT CIRCULATION
(FR) GROUPE MOTOPROPULSEUR AVEC UNE BOITE DE VITESSES PILOTEE EN TEMPERATURE PAR CIRCULATION D'UN FLUIDE DE REFROIDISSEMENT
Abstract:
(EN) The invention relates to a method for controlling the temperature of a gearbox, in particular an automatic gearbox, including a heat exchanger (6) and associated with an internal combustion engine (1) cooled by coolant circulation, a lubricating oil of the gearbox being maintained at an operating temperature, a first supply of the heat exchanger (6) with coolant from the engine (1) being effective for cooling the gearbox once the internal combustion engine has reached a so-called regulation temperature. Below the operating temperature of the lubricating oil, a second supply of the heat exchanger (6) with coolant is effective, in which case the coolant performs a heating action on the oil, as long as the outside temperature is above a minimum temperature threshold.
(FR) L'invention porte sur un procédé de pilotage en température d'une boîte de vitesses, notamment automatique, comprenant un échangeur (6) de chaleur et associée à un moteur (1) à combustion interne refroidi par circulation d'un fluide de refroidissement, une huile de lubrification de la boîte de vitesses étant maintenue à une température de fonctionnement, une première alimentation de l'échangeur (6) de chaleur en fluide de refroidissement du moteur (1) étant effective pour le refroidissement de la boîte de vitesses dès que le moteur à combustion interne a atteint une température dite de régulation. En dessous de la température de fonctionnement de l'huile de lubrification, une deuxième alimentation de l'échangeur (6) de chaleur en fluide de refroidissement est effective, le fluide de refroidissement effectuant alors une action de chauffage sur l'huile, à condition que la température extérieure soit au-dessus d'un seuil de température minimale.
