摘要： The invention relates to an oil supply system of an automatic transmission or an automated manual transmission in a powertrain 1.1 having an oil pan (1); 1.2 having a pressure line (2, 12, 22, 32) for supplying elements (17, 18, 19, 20) of the transmission with pressurized oil; 1.3 having a pump device (3) for pumping oil from the oil pan (1) into the pressure line (2, 12, 22, 32) at a supply pressure P
0 ; 1.4 having, as a starting element, a hydrodynamic transducer (18) which forms a portion of the pressure line; 1.5 having a hydrodynamic retarder in a retarder oil circuit (23) 1.6 having at least a first switching valve (8), a second switching valve (9) and a heat exchanger (33), the heat exchanger (33) being selectively switchable, by means of the switching valves (8, 9), as a portion in the pressure line (2, 12, 22, 32) or the retarder oil circuit (23). The invention is characterized in that a temperature sensor (36a) is provided downstream of the pump device (3) in the direction of flow in order to measure the oil temperature in the pressure line (2, 12, 22, 32).-

摘要： The invention relates to a method for setting the working pressure of a transmission, in particular a motor vehicle transmission, the transmission having clutches, brakes, actuators, a hydrodynamic coupling and/or a hydrodynamic converter, to which a medium carrying the working pressure can optionally be supplied in order to vary the transmission ratio of the rotational speed and/or the torque between a transmission input shaft and a transmission output shaft by opening and closing the clutches and/or brakes, by operating actuators and/or by hydrodynamic transmission of power by using the hydrodynamic coupling and/or the hydrodynamic converter, it being possible for the working pressure to be switched between a constant nominal value and a constant lowered value that is smaller relative thereto, or for the working pressure to be reduced from the nominal value to a lowered value in three or more stages or continuously. The invention is characterized in that a difference in rotational speed between the transmission input shaft and the transmission output shaft and/or between the input side and output side of at least one clutch, brake, the hydrodynamic coupling and/or the hydrodynamic converter is detected and compared with a predefined intended difference, and the switching or reducing of the working pressure is carried out as a function of the result of the comparison.

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.
