Aufgabe der Erfindung ist es, ein Getriebe für ein Kraftfahrzeug, das als ein mit Schaltmuffen versehenes Schaltgetriebe mit einer mehrere Kupplungen, vorzugsweise eine Doppelkupplung aufweisenden Kupplungseinrichtung zusammenarbeitet, zu schaffen, das unter Einsatz einfach zu realisierender Komponenten sich durch eine hervorragende Funktion auszeichnet.The object of the invention is to provide a transmission for a motor vehicle, which cooperates as a provided with shift sleeves gearbox with a plurality of clutches, preferably a dual clutch having clutch device, which is characterized by using easy-to-implement components by an excellent function.
Nach der Erfindung wird diese Aufgabe durch ein Getriebe mit den Merkmalen der Patentansprüche 1, 2 und/oder 4 sowie durch ein Verfahren nach Patentanspruch 3 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den nachfolgenden Patentansprüchen enthalten.According to the invention, this object is achieved by a transmission with the features of
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass der erste Kupplungsdruckregler und der zweite Kupplungsdruckregler, die jeweils nach Art eines einen Elektromagnet aufweisenden Schieberventils ausgebildet sind, eine sichere Betätigung zum Gangwechsel des Schaltgetriebes gewährleisten. Diese Kupplungsdruckregler in Verbindung mit dem Verfahren zu ihrer Steuerung ermöglichen eine gute Funktion der Doppelkupplung des Getriebes. Die den Hydraulikzylindern unmittelbar nachgeschalteten nach Art von Schaltventilen aufgebauten Schalteinrichtungen verfügen über einen relativ großen Querschnitt zur Tankleitung, wodurch eine relativ rasche Entleerung der Zuleitung zum Tank erreichbar ist; besagte Entleerung bewirkt eine schnelle Trennung der zugehörigen Kupplung. Den beiden Kupplungsdruckreglern, die unter Zwischenschaltung der Schalteinrichtungen die erste Kupplung und die zweite Kupplung der Doppelkupplung beeinflussen, ist ein Druckerhaltungsventil vorgeschaltet, das dafür sorgt, dass der jeweilige Funktionsdruck in den Zuleitungen zu den Kupplungszylindern innerhalb eines betriebsgerechten Arbeitsdrucks eingestellt ist.The advantages achieved by the invention are to be seen in the fact that the first clutch pressure regulator and the second clutch pressure regulator, which are each designed in the manner of a solenoid valve having a solenoid, ensure safe operation for changing gear of the gearbox. These clutch pressure regulators in conjunction with the method of their control allow a good function of the dual clutch of the transmission. The hydraulic cylinders immediately downstream connected in the manner of switching valves constructed switching devices have a relatively large cross-section to the tank line, whereby a relatively rapid emptying of the supply line to the tank can be achieved; said emptying causes a rapid separation of the associated coupling. The two clutch pressure regulators, which influence the first clutch and the second clutch of the dual clutch with the interposition of the switching means, a pressure-holding valve is connected upstream, which ensures that the respective operating pressure is set in the supply lines to the clutch cylinders within a working operating pressure.
Vorteilhaft bezüglich Realisierbarkeit und Wirksamkeit bei dem Schaltgetriebe mit mehreren Schaltmuffen, das mit der ein erstes Teilgetriebe und eine zweites Teilgetriebe des besagten Schaltgetriebes beeinflussenden Doppelkupplung zusammenarbeitet, ist, dass jedes Teilgetriebe Steuerungselemente besitzt, die durch Schaltaktuatoren gebildet werden. Um das Getriebe bzw. das Schaltgetriebe mit den Schaltmuffen im Zusammenhang mit diesen Steuerungselementen funktionsgerecht zu betreiben, eignet sich das hierzu entwickelte Verfahren.Advantageous in terms of feasibility and effectiveness in the transmission with multiple shift sleeves, which cooperates with the first partial transmission and a second partial transmission of said gearbox influencing dual clutch is that each partial transmission has control elements, which are formed by switching actuators. In order to functionally operate the transmission or the manual transmission with the sliding sleeves in connection with these control elements, the method developed for this purpose is suitable.
Darüber hinaus setzt das Getriebe, das als Schaltmuffen aufweisendes Schaltgetriebe ausgebildet ist und mit einer mehrere Kupplungen besitzenden vorzugsweise als Doppelkupplung dargestellten Kupplungseinrichtung zusammenarbeitet, sowohl hinsichtlich Einsatz an Bauelementen und auch Wirkung Maßstäbe. Hierzu tragen inter alia die Steuerungselemente zum Bewegen der Schaltmuffen und die Kupplungsdruckregler bei.In addition, the transmission, which is designed as a shift sleeves having shift gear and cooperating with a plurality of couplings preferably acting as a double clutch coupling device cooperates, both in terms of use of components and also performance standards. Inter alia, the control elements for moving the sliding sleeves and the clutch pressure regulators contribute to this.
In den Zeichnungen werden Ausführungsbeispiele der Erfindung gezeigt, die nachstehend näher erläutert werden.In the drawings, embodiments of the invention are shown, which are explained in more detail below.

- (9) the pressure in the supply line decreases until the force of the electromagnet and the reference force are in equilibrium.
