Abstract

A lubrication system for a vehicle includes a heat exchanger having a lubricant inlet and a lubricant outlet with the lubricant outlet having a first outlet branch and a second outlet branch. The lubrication system also includes a stator lubrication circuit, a rotor lubrication circuit, and a gearbox lubrication circuit fluidly connected between the lubricant inlet and the first outlet branch. The gearbox, stator, and rotor lubrication circuits are connected fluidly in parallel with each other. The system also includes a park actuator assembly having a parking pawl configured to move between a parking position and a release position allowing movement of the drivetrain gear and a park actuated valve configured to move into a first position blocking lubricant flow through the second outlet branch when in the parking position and into a second position allowing lubricant flow through the second outlet branch when in the release position.
