摘要:
The invention relates to a transmission oil circuit with an oil pump for conveying oil or another medium from an oil sump or associated media sump, comprising: a heat exchanger through which the oil flows in order to remove heat from the oil; with a working pressure valve, against which the oil pump conveys the oil in order to bring the conveyed oil to a predetermined working pressure for pressure actuating, pressure oil application or pressure oil supply of switching valves and/or other transmission components and/or other aggregates outside of the transmission that are arranged in the flow direction upstream from the working pressure valve in a row thereto or in the flow direction downstream from a supply line that branches upstream from the working pressure valve in the transmission oil circuit. The invention is characterized in that the heat exchanger can be switched in a first position upstream or in a second position downstream from the working pressure valve in an alternating manner regarding the sequence of the flow with oil originating from the oil pump, or the heat exchanger can be switched in a first position upstream or in a second position downstream from the switching valves, other transmission components and/or other aggregates or with an arrangement in or downstream from the branched supply line, upstream or downstream from the branching point regarding the sequence of the flow with oil originating from the oil pump in an alternating manner.

The invention relates to a hybrid drive unit in which a multi-geared clutch and transmission assembly is provided for as optimum of a synergistic utilization of motive energy from an internal combustion engine and from an electric motor as possible, wherein both the internal combustion engine drive output and the electric motor drive output are introduced to an input member of the clutch and transmission assembly. This facilitates numerous drive variations which allow the drive mechanisms to cooperate with one another as the need calls for. The invention also relates to the method for operating such a drive unit.

In an oil pump for an automatic transmission, a suction port is adapted to be connected to a first suction passage. The first suction passage is arranged in parallel with a second suction passage connected to an auxiliary pump. The first and second suction passages branch from an upstream suction passage leading to an oil strainer. A discharge outlet is adapted to be connected to a first discharge passage. An air vent hole is disposed downstream of the suction port and upstream of the discharge outlet. A communication passage is connected to the air vent hole and adapted to reach a predetermined oil level in an oil pan so as to communicate the air vent hole with inside of oil in the oil pan.

Bei einer solchen Lagerung ist erfindungsgemäß vorgesehen, dass das Pumpenrad und die Pumpenwelle als einstückige Anordnung ausgebildet sind.
摘要:
A system and method are provided for monitoring a vehicle hydraulic system having a plurality of hydraulic function elements (50, 52, 54, 60, 62, 70). The hydraulic system includes a hydraulic pump (12) for supplying pressurized hydraulic fluid to the plurality of hydraulic function elements (50, 52, 54, 60, 62, 70) via a corresponding plurality of hydraulic element control valves (16, 20), an electronic control unit (40) for controlling the element control valves (16, 20). The pump (12) also supplies lube fluid to a lubrication circuit if requirements of the hydraulic function elements (50, 52, 54, 60, 62, 70) are met. The method includes sensing a hydraulic pressure, and comparing the sensed pressure to a threshold pressure. If the sensed pressure is less than threshold pressure, then actively engaged hydraulic elements (50, 52, 54, 60, 62, 70) are tested by disengaging the elements (50, 52, 54, 60, 62, 70) in a predetermined manner, checking to see if the sensed low pressure condition is eliminated. If the sensed low pressure condition is eliminated after disengaging an element, then the leaking hydraulic function element is deactivated.
