    摘要: The invention relates to a hydraulic control apparatus (1) for an automatic dual clutch transmission, which includes a first clutch (9) with a first partial transmission and a second clutch (13) with a second partial transmission, as well as a shifting system (12) for engaging/releasing gears of the two partial transmissions. The control apparatus (1) is distinguished by the fact that a first switching valve (7) in a position AI connects a first pressure regulator (3) to the first clutch (9) and disconnects it from the shifting system (12) and in a position BI connects the first pressure regulator (3) to the shifting system (12) and disconnects it from the first clutch (9), and that a second switching valve (8) in a position AII connects a second pressure regulator (4) to the second clutch (13) and disconnects it from the shifting system (12) and in a position BII connects the second pressure regulator (4) to the shifting system (12) and disconnects it from the second clutch (13). The invention also relates to a method for controlling the dual clutch transmission using the control apparatus (1).

    摘要: The invention relates to a hydraulic system (1) for providing pressures and volumetric flows in a dual clutch transmission, in particular for providing a first volumetric flow for cooling and lubricating a first clutch (2) and for providing a second volumetric flow for cooling and lubricating a second clutch (3). The hydraulic system is distinguished by the fact that at least one switching valve (4), which in a first position guides a lubricating flow onto the first clutch (2) and a cooling flow onto the second clutch (3) and in a second position guides the lubricating flow onto the second clutch (3) and the cooling flow onto the first clutch (2), is connected upstream of the first clutch (2) and the second clutch (3). The cooling flow is preferably variable.

    摘要: The invention relates to a hydraulic control apparatus (1) for a shifting fork (7) for engaging/releasing at least one gear (G) in a manual transmission, comprising at least one shifting cylinder (2, 3) and a piston unit (6) which can move within the shifting cylinder and is connected to the shifting fork (7), and at least one control valve (8) for generating a modeled pressure which can be applied to the piston unit (6) in order to actuate the shifting fork (7). To prevent jolting when the piston unit is started up, the invention proposes a valve apparatus which provides a counter-pressure which counteracts the movement of the piston unit (6). In a preferred exemplary embodiment, a diaphragm ensures that the counter-pressure drops below the value preset by the valve apparatus at low speeds on the part of the piston unit.
