    摘要： A method for operating a hydraulic device (1) of a transmission device having a variable displacement pump (2) that can be supplied with a hydraulic pressure (p_B) in order to vary the output in the area of an adjusting device (3), and having at least two pressure circuits (PK, SK) that can be connected to a discharge side (24) of the adjustable displacement pump (2) and are assigned different priorities with regard to the supply of hydraulic fluid by the pump. When a change is needed to the operating state of the transmission device for the implementation of which the output of the variable displacement pump (2) must be elevated relative to its current output, a pressure (p_B) applied in the region of the adjusting device (3) by a pressure return (5) is correspondingly modified before changing the operating state.

    摘要： A method for emergency actuation of an automated dual-clutch transmission of a vehicle with electrohydraulic control via a transmission control device. The method includes disengaging one clutch of the dual-clutch transmission, in order to realize emergency operation of the transmission and applying pressure on the other clutch after an error signal is transmitted indicating a malfunction of the transmission and/or the transmission control device. In order to keep the complexity of the hardware of the hydraulic system low, both clutches are disengaged, when an error signal occurs, and adjusted to a safe initial state, and an actuating pressure is only re-applied to one of the two clutches after the initial state is reached. In addition to the already existing elements of the hydraulic system, only one device or software is required which detects and selects the clutch that is more advantageous for continued driving operation.

    摘要： A bypass valve for a cooler connected downstream from a hydraulic aggregate. The bypass valve includes a housing with ports for connection to the hydraulic aggregate and the cooler. A closure element is located in the housing for closing and opening a bypass. A spring pushes the closure element into a closing position, and thermo-sensitive means causes the closure element to open if the temperature of the hydraulic fluid is below a threshold temperature. The thermo-sensitive means are formed by the valve spring, which is made of a memory-metal alloy with a transition point close to the threshold temperature such that below the threshold temperature it no longer exerts a force and allows the closure element to open.

    摘要： A device for the hydraulic control of an automatic transmission, especially a continuously variable automatic transmission. The control system comprises a forward/reverse drive unit (4), which is controlled by way of at least a first and a second shifting component (5, 6). The shifting components (5, 6) are in turn controlled via at least two valves (7, 8, 17, 18, 20, 21), which are pressurized by way of a pressurized medium pump (9). A gear selector device (15) selection is made among at least a forward gear (D), a neutral gear (N) and a reverse gear (R), wherein the selector device (15) possesses a non-mechanical connection to the transmission control system.
