摘要： An actuating device for a shift element of a transmission which is acted upon by a hydraulic actuating pressure (p_B1) and comprises a valve device. To vary the actuating pressure (p_B1), the valve device is acted upon by a control pressure (p_EDS) in an area of active surfaces (A18, A19) of at least a first and a second valve slides. An active surface (A38) of the first valve slide (A8) is acted upon by a hydraulic pressure (p_B2) which is equivalent to the actuating pressure (p_B1), acts in opposition to the control pressure (p_EDS) and can be adjusted as a function of the control pressure (p_EDS) applied, such that a smaller variation of the actuating pressure (p_B1) results from a change of the control pressure (p_EDS) within a first pressure range of the control pressure (p_EDS) than within a second pressure range of the control pressure (p_EDS).

摘要： A method for operating a drivetrain of a motor vehicle including a hybrid drive with a combustion engine and an electric motor. A transmission is arranged between the hybrid drive and a drive output and a clutch is arranged between the combustion engine and the electric motor so that, if a failure occurs in the drivetrain, especially in a transmission control device of the transmission, a gear corresponding to an emergency gear is engaged or remains engaged in the transmission. When the emergency gear is engaged, the motor vehicle is in motion and the engine speed falls below a defined value, the clutch arranged between the combustion engine and the electric motor disengages.

摘要： A hydraulic system for actuating an interlocking shifting element of a transmission which comprises two piston chambers and a piston element that delimits the piston chambers. The piston element can be acted upon in one piston chamber by a pressure to open the shifting element and, in the other piston chamber, by another pressure to close the shifting element. Pressure can be delivered by a valve to two piston chamber and the valve can be actuated by an actuator by a pilot pressure. The valve and the electro-hydraulic actuator are designed and functionally connected to one another such that, in the event of a pressure drop, a total hydraulic force, acting to close the shifting element, is applied to the piston element and, if the current supply to the actuator fails, a total hydraulic force acting, in the opening direction of the shifting element, acts upon the piston element.

摘要： A method of operating a valve system of a transmission comprising part of the vehicle drive train through a valve unit and said valve unit's electro-magnetic activator configuration. In a transmission's hydraulic system and is part of the vehicle drive train, its hydraulic pressure value (p_EDS) can be employed and adjusted through a valve unit configuration by applying a pulse-width-modulated current signal (i_EDS) to the electro-magnetic activator system. The pulse-width modulated current signal (i_EDS) and its amplitude (A) and/or its pulse duration (pw1) will periodically change, during the applied Dither-Modulation, by maintaining the required pressure value (p_EDS) at the same time, whereby a lengthwise movable anchor, which is attached a valve shaft of the valve system, receives hereby an imposed vibrating oscillation. According to the invention, the Dither-Modulation is activated or deactivated during pre-defined operating conditions of the vehicle drive train.

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： An electrohydraulic control device (1) of an 8-speed transmission having several electrically controllable pressure control valves (6-12) for hydraulically actuating five switching elements (A-E) and an electric gear control unit via which different operating states of the transmission may be adjusted. Three of the switching elements are connected in the force flow of the transmission for representing a gear ratio (“1” to “R”) of the transmission. When the gear control unit is de-activated and the power supply to the solenoid valve and pressure control valves is interrupted, and when the transmission is in the operating state, in which a gear ratio (“1”; “2”; “3”; “4”; “5”; “6”; “7”; “8”; “R”) is engaged, a predefined emergency transmission (“6”; “R”) is represented by three simultaneously hydraulically connected switching elements (C, D, E, A, B, D).
