WHEEL CLUTCH TRANSMISSION ELEMENT FOR A HYBRID TRACTION CHAIN OF A MOTOR VEHICLE, A LUBRICATING AND / OR COOLING METHOD, AND A CONTROL THEREFOR, AND A MOTOR VEHICLE EQUIPPED WITH SUCH ELEMENT

摘要

The invention concerns an element comprising an electrical machine (31), two wet clutches (33, 35), a cooling fluid circuit, including a chamber (53) for cooling the clutches (33, 35), a fluid tank (251), and a pump (255). The pump (225) is connected to a recycling channel (259), the cooling circuit comprising selecting means (257) arranged upstream of the pump (255), such that said pump is capable of selectively feeding said chamber (53) from the tank (251) and from the recycling channel (259) based on the temperature of the fluid passing through the selecting means (257). The invention also concerns an associated cooling and/or lubricating, and clutch control method, as well as a motor vehicle equipped with such a transmission document.
