摘要： The invention relates to a method for controlling a hydrodynamic retarder in a motor vehicle, which hydrodynamic retarder can be disengaged by a disconnect clutch. The motor vehicle has a drive motor, the power output of which can be controlled by means of an actuator such as a foot pedal or lever and which drive motor is operated in a first operating state, called traction operation, in dependence on the operation of the actuator, in which traction operation drive power of the drive motor is transmitted to drive wheels by means of a drive train of the motor vehicle in order to accelerate the motor vehicle, and in a second operating state, called overrun operation, in which drive power is transmitted from the drive wheels into the drive train. The hydrodynamic retarder has a driven bladed rotor and a bladed stator or a driven bladed rotor and a bladed counter-rotating rotor driven in a direction opposite the direction of the driven bladed rotor, which together form a working chamber that can be filled with a working medium and drained of said working medium, and the rotor can be selectively disengaged from the drive train and connected to the drive train in a rotationally fixed manner by means of a disconnect clutch, such that, in braking operation initiated by a vehicle driver or driver assistance system, the rotor is driven via the closed disconnect clutch in relation to the stationary stator or in a direction opposite the direction of the counter-rotating rotor and, with the working chamber filled, torque is transmitted from the rotor to the stator or the counter-rotating rotor, and, in non-braking operation initiated by the vehicle driver or the driver assistance system, with the disconnect clutch open, the drive power transmission to the rotor and/or the counter-rotating rotor is interrupted and the working chamber is drained of the working medium. In the transition from the non-braking operation to the braking operation, the disconnect clutch is closed and the working chamber is filled with working medium, and, in the transition from the braking operation to the non-braking operation, the working chamber is drained of the working medium and the disconnect clutch is opened simultaneously or at a delay. The method is characterized in that, in the overrun operation, an acceleration of the motor vehicle is detected or determined and compared with a specified acceleration limit value, and, in the non-braking operation, the disconnect clutch is closed independently of an initiation of the braking operation by the vehicle driver or the driver assistance system and the working chamber is kept drained if the acceleration lies above the acceleration limit value.

摘要： The invention relates to a hydrodynamic retarder comprising a bladed rotor and a bladed stator which together form a working chamber that can be filled with or emptied of a working medium, comprising a working medium container for receiving working medium which is not currently located in the working chamber, comprising a control pressure application system for supplying a control pressure medium to the working medium contained in the working medium container such that more or less working medium is displaced out of the working medium container into the working chamber in order to set a desired braking torque, and comprising a centrifugal separator (6) for separating the working medium from the control pressure medium. The centrifugal separator (6) is fluidically connected to a working medium container outlet for the control pressure medium so as to be pressurized with the control pressure medium, and the centrifugal separator is driven by the pressure of the control pressure medium.

摘要： The invention relates to a hydrodynamic retarder comprising - a rotor (1) and a stator (2) which form a working chamber (3) with each other; - a first working medium connection (6); - a second working medium connection (7); and - a working medium container (4) that has an outlet (10), which is connected to the first working medium connection via a line, and an inlet (11), which is connected to the second working medium connection via a line; wherein - the working medium container is made of two housing parts (8, 9), which are joined together along a parting line (12). According to the invention: - the two housing parts together enclose the working medium storage volume; - one of the two housing parts simultaneously forms a part of a retarder housing (14) which supports or forms the stator and partly forms all or some of the working medium-conducting connections between the working medium storage volume and the working chamber; and - a separating plate (13) is inserted between the two housing parts, said separating plate together with one or both of the housing parts forming cavities for the working medium-conducting connections and/or the working medium storage volume.

摘要： The invention relates to a motor vehicle drive train including a driving engine and driven wheels which are driven by the driving engine via a main branch. The drive train further includes a hydrodynamic retarder comprising a revolving rotor and a stator or a revolving rotor and a counter-rotating twin rotor which jointly form a working chamber that is or can be filled with a working medium. The drive train also includes a disconnect clutch which allows the rotor of the hydrodynamic retarder to be disengaged from a driving power flow in the drive train. The invention is characterized in that the hydrodynamic retarder is connected to the main branch via an at least two-stage transmission comprising at least one intermediate shaft and a rotor shaft which drives or supports the rotor, the intermediate shaft forming at least one first transmission stage along with the main branch while forming at least one second transmission stage along with the rotor shaft. Furthermore, the disconnect clutch is arranged on the intermediate shaft.

摘要： The invention relates to a method for preventing pressure peaks in a working medium cycle in which a hydrodynamic machine is operated, wherein the hydrodynamic machine comprises a primary wheel and a secondary wheel which together form a toroidal working chamber that can be filled and emptied via a working medium inlet and working medium outlet in order to hydrodynamically transmit torque from the primary wheel to the secondary wheel. The invention is characterized in that the rate of change of the flow cross-section for the working medium that flows into and/or out of the working chamber is changed depending on a predetermined input variable when connecting and disconnecting the hydrodynamic machine.

摘要： Die Erfindung betrifft ein Verfahren zum Steuern eines über eine Trennkupplung mechanisch abkoppelbaren hydrodynamischen Retarders in einem Kraftfahrzeug, welcher einen umlaufenden beschaufelten Rotor und einen beschaufelten Stator oder einen umlaufenden beschaufelten Rotor und einen in Gegenrichtung hierzu umlaufenden beschaufelten Gegenlaufrotor aufweist, die gemeinsam einen in einem Bremsbetrieb mit Arbeitsmedium befüllten und in einem Nichtbremsbetrieb vom Arbeitsmedium entleerten Arbeitsraum ausbilden, wobei der Rotor im Bremsbetrieb über einen Antriebsstrang mit einer geschlossenen Trennkupplung angetrieben wird und beim Übergang vom Bremsbetrieb zum Nichtbremsbetrieb der Arbeitsraum entleert und die Trennkupplung geöffnet wird, wobei der Übergang vom Bremsbetrieb zum Nichtbremsbetrieb durch eine Retarderausschaltanforderung eines Fahrerassistenzsystems oder durch Betätigen einer Eingabevorrichtung durch einen Fahrzeugführer initiiert wird, und der Übergang vom Nichtbremsbetrieb zum Bremsbetrieb durch eine Retardereinschaltanforderung des Fahrerassistenzsystems oder durch Betätigen einer Eingabevorrichtung durch den Fahrzeugführer initiiert wird.
Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass unabhängig von der Retardereinschaltanforderung des Fahrerassistenzsystems oder durch Betätigen der Eingabevorrichtung durch den Fahrzeugführer die Trennkupplung zu Beginn eines Anfhanvorgangs des Kraftfahrzeugs geschlossen wird, wenn in einem Stillstand des Kraftfahrzeugs der Arbeitsraum mit Arbeitsmedium befüllt ist.
