摘要： A hydraulic control system for an all wheel drive vehicle includes a brake control unit having an electric motor driven pump selectively providing pressurized fluid to a first brake cylinder. An all wheel drive coupling is adapted to selectively transfer torque from an engine to a secondary driveline that includes a piston positioned within a cavity to apply an actuation force to a clutch. A hydraulic control unit is in receipt of pressurized fluid from the pump and includes a first valve selectively isolating pressurized fluid from the cavity and a second valve moveable between a first position where the cavity is in fluid communication with the first valve, and a second position where the cavity is in fluid communication with a fluid reservoir of the brake control unit.

摘要： A power transmission device includes a rotatable shaft having an axis of rotation. A lubrication pump (48) includes an inner rotor (70) and an outer rotor (72) in meshed engagement with one another. A clutch (90) continuously drivingly couples one of the inner rotor and the outer rotor and the shaft to limit the power transferred from the shaft to the lubrication pump. The clutch includes a plurality of circumferentially spaced-apart protrusions (92) biasedly engaged with the shaft (44).
摘要翻译：动力传递装置包括具有旋转轴的旋转轴。润滑泵（48）包括彼此啮合的内转子（70）和外转子（72）。离合器（90）连续地驱动地连接内转子和外转子和轴之一，以限制从轴传递到润滑泵的功率。离合器包括与轴（44）偏置地接合的多个周向间隔开的突起（92）。
