    摘要： Die Erfindung betrifft einen Antriebsstrang eines Kraftfahrzeugs, wobei der Antriebsstrang zumindest einen Hybridantrieb mit einem Verbrennungsmotor und einer Elektromaschine, eine zwischen den Verbrennungsmotor und die Elektromaschine geschaltete Kupplung (5), ein zwischen dem Hybridantrieb und einem Abtrieb angeordnetes Getriebe, sowie ein Anfahrelement umfasst, wobei dem Getriebe eine Haupthydraulikpumpe, die unter anderem zum Schließen der zwischen den Verbrennungsmotor und die Elektromaschine geschalteten Kupplung (5) vorgesehen ist. Erfindungsgemäß, sind der Kolbenraum (13) und der Druckausgleichsraum (14) der Kupplung (5) derart dimensioniert, dass bei ausgefallener Elektromaschine des Hybridantriebs und bei geöffneter sowie elektrisch angesteuerter Kupplung (5) ab einer definierten Grenzdrehzahl des Verbrennungsmotors des Hybridantriebs im Kolbenraum (13) ein Rotationshydraulikdruck herrscht, der die zwischen den Verbrennungsmotor und die Elektromaschine geschaltete Kupplung (5) zumindest soweit schließt, dass dieselbe ein Drehmoment überträgt, welches so groß ist, dass die Haupthydraulikpumpe einen zum weiteren Schließen der Kupplung (5) erforderlichen Hydraulikdruck im Kolbenraum (13) bereitstellt.

    摘要： A method of controlling a pressure control valve assembly (69) to control a control pressure (43,71) in a system (11) including a source (47,49) of pressurized fluid. The control valve assembly is operable to vary the control pressure in response to variations in an electrical input signal (87) to an electromagnetic coil (81). The control valve assembly defines an inlet (77) in communication with the control pressure, an outlet (93) in communication with the low pressure, and a valve seat (89) disposed intermediate the inlet (77) and the outlet (93). A poppet valve member (91) is biased toward the valve seat by a biasing means including an armature (95), the biasing force being generally proportional to the input signal to the coil. The method comprises the steps of selecting a predetermined, minimum pressure for the control pressure corresponding to a minimum condition of the system. Next is selecting the biasing means to apply a biasing force to the poppet valve (91) corresponding to a fluid pressure less than the predetermined minimum pressure for the control pressure. The last step is selecting the electrical input signal (87) to correspond to the desired control pressure, an increasing input signal resulting in an increasing biasing force on the poppet valve member (91), but with no substantial movement thereof.

    摘要： The invention relates to a rotational speed differential dependent hydraulic clutch comprising a rotating drive housing (27) located in a non-movable housing (25) which forms a reservoir, a hydrostatic displacement machine (35), an output shaft (30), a friction clutch (36) and a piston (5) which impinges upon said friction clutch (36). The occurrence of a rotation speed differential between the drive housing (27) and the brake shaft (30) in a pressure chamber (4) generates a pressure which impinges upon the friction clutch (36). In order to effect a rapid regulation and adaption of the characteristic, the first and the second openings (9, 10) are respectively connected to the reservoir (8) by means of afirst and second rotational input (13, 14) and a first and a second control valve (15, 16), whereby the first and second control valve (15, 16) are embodied as a controllable throttle in such a way that, independent of the direction of the rotational speed differential, a controlling intervention occurs at the inlet and outlet side of the displacement machine.
