摘要： A device for controlling a hydraulically operable switching element (2) of an automatic transmission of a vehicle with a position valve mechanism (3) having a main switch piston (6) which is spring biased into a first switch position and a second switch position with a pilot pressure (P_MV) which is adjustable through an electrically operated actuator (5). An additional switch piston (7) and the main switch piston (6) are axially actuated in a valve housing (8). Depending on the position of the pistons (6, 7), faces (6A, 7A) of the respective pistons are either spaced apart or adjacent. The additional switch piston (7) is adjustable depending on a pilot pressure (p_K) of a switching element which engages a gear for forward drive.

摘要： Description of a hydraulic control system (1A) for a hydrodynamic torque converter (1) with a controlled torque converter lockup clutch (2) of an automatic transmission for controlling a supply pressure (p_WD_zu) of the torque converter (2) and a supply pressure (p_WK_zu) of the torque converter lockup clutch (2). The torque converter lockup clutch (2) is engaged when the supply pressure (p_WD_zu) of the torque converter (1) is lower than a predefined pressure level of the supply pressure (p_WK_zu) of the torque converter lockup clutch. A converter pressure valve (WDV) is provided for controlling the supply pressure (p_WD_zu) of the torque converter (1), and a converter coupling valve (WKV) for controlling the supply pressure (p_WK_zu) of the torque converter lockup clutch, where their valve slides (WDV_S, WKV_S) can be acted upon by at least one pre-control pressure (p_VS) and one system pressure (p_sys). When the torque converter lockup clutch (2) is disengaged, the valve slide (WKV_S) of the converter coupling valve (WKV) is acted upon in such a way on an active surface (15) by the reverse pressure (p_WD_ab) of the torque converter (1), and when the torque converter lockup clutch (2) is engaged, is acted upon in such a way on the active surface (15) by the reverse pressure (p_WK_zu) of the torque converter lockup clutch (2), that at least either the supply pressure (p_WD_zu) of the torque converter (1) or the supply pressure (p_WK_zu) of the torque converter lockup clutch (2) is higher than a predefined pressure level (p—0) over the entire operational area of the torque converter (1).

摘要： A hydraulic system of a transmission, for an automatic transmission of a motor vehicle, having several pressure circuits which can be loaded with hydraulic fluid from a pressure source and in relation to the supply of different areas of the transmission are differently prioritized. The pressure in the pressure circuits is adjustable according to a system valve and one of the pressure circuits comprises a cooling device for the hydraulic fluid and a lubrication circuit located downstream of the cooling device. Between the cooling device and the lubrication circuit is provided a bypass pipe, blockable via a valve unit, which can be controlled via the valve unit so that the hydraulic fluid flow rate to be passed via the cooling device can be adjusted without changing the hydraulic fluid flow rate to be fed to the lubrication circuit.

摘要： A hydraulic transmission unit comprises at least one pressure regulation valve (1) and a pilot control valve (2) which is connected to the pressure regulation valve (1) by a pilot control line (35). A pre-filling valve (3, 303) sets a pre-filling pressure (p—3) to avoid draining of a clutch (20) and the lines (231, 331) connected to the clutch (20) in an operating condition in which the clutch (20) is not actuated. To avoid draining when the clutch when in the operating condition, the pilot control line (35) is also connected to at least one line (236, 238, 336, 338) which is pressurized with a second pre-filling pressure (p—3).

摘要： A method for monitoring frictional engagement in an automatic or automated motor vehicle transmission having a hydrodynamic starter element when the transmission is in a preset neutral or parking position and the automatic or automated motor vehicle transmission controlled by this method. When the motor vehicle is at or close to a standstill in a preset neutral or parking position, the current transmission rotational input speed and a current engine rotational speed of the drive motor are determined and based on the speed ratio between the current transmission rotational input speed and the current engine rotational speed an error is found to be present if the speed ratio is less than a predefined threshold value, which is less than/equal to 1.

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 control valve arrangement for controlling a start coupling of an automatic gearbox comprising a clutch control valve (3, 37, 41, 48, 49) for controlling at least one clutch actuating device (4, 40) which, during normal operation of the gearbox, converts a supply pressure input (P_V1, P_V2) into a clutch actuation pressure (P_K, P_K1, P_K2) according to a pre-control pressure or an electric pre-control signal in order to control the clutch actuation device. An activating pressure (P_A) can be supplied to the clutch control valve or directly to the clutch activation device in the event of a discontinuation of the pre-control pressure or pre-control signal according to the engine and gearbox output speed, whereupon the clutch actuation device is maintained in a closed position as long as the above mentioned speed remains above a predetermined limit.
