    摘要: A proportional pressure control valve is described, which comprises a valve part (1) with outlet and inlet openings (4) and at least one closing element (2) for the control of an orifice (5). The hydraulically effective cross-section of the valve part (1) is determined by the size and shape of the inlet opening (4). The axial longitudinal axis of the inlet opening (4) is perpendicular to the longitudinal axis of the closing element (2). The resultant force action on the closing element (2) has an advantageous effect on the quality of the valve function especially at low temperatures.

    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 of operating a transmission of a vehicle drive-train that comprises frictional shifting elements and an interlocking shifting element. In the neutral operating condition of the transmission, and in the case of an operating condition variation of the vehicle drive-train in which, when it is required to establish the force flow in the transmission, the interlocking shifting element is to be changed from a disengaged to an engaged operating condition, by increasing the transmission capacities of at least two frictional shifting elements which have to be engaged for producing the force flow, a rotational speed difference in the area of the interlocking shifting element is determined, and a drive torque of a drive machine is adjusted to a level that brings the speed difference within a predefined range at which the interlocking shifting element is approximately synchronized and can therefore be engaged.

    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.
