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.task The invention is a transmission for a motor vehicle, as a gearbox provided with shift sleeves with a plurality Couplings, preferably a double clutch clutch device working together to create that using easy to implement Components are characterized by an excellent function.
Nach der Erfindung wird diese Aufgabe unter anderem durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den nachfolgenden Patentansprüchen enthalten.To The object of the invention is, inter alia, by the features of claim 1. Further, the invention ausgestaltende features are in the following Claims contained.
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 gewährleistet ist. 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 with the invention mainly achieved advantages are the fact that the first clutch pressure regulator and the second clutch pressure regulator, each in the manner of a an electromagnet having slide valve are formed, a safe operation ensures the gear change of the gearbox. This clutch pressure regulator in conjunction with the method for their control a good function of the dual clutch of the transmission. The hydraulic cylinders directly downstream switching devices constructed in the manner of switching valves have one relatively large Cross-section to the tank line, resulting in a relatively rapid emptying the supply line to the tank is accessible; said emptying causes a quick separation of the associated clutch. The two clutch pressure regulators, with the interposition of Switching devices, the first clutch and the second clutch of the Affect double clutch, a pressure maintenance valve is upstream, for that ensures that the respective working pressure in the supply lines to the Clutch cylinders within a proper working pressure is set.
Vorteilhaft bezüglich Realisierbarkeit und Wirksamkeit bei dem Schaltgetriebe mit mehreren Schaltmuffen, das mit der ein erstes Teilgetriebe und eine zweites Teilgetriebe des besagten Schaltgetriebes beeinflussbaren 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 manual transmission with multiple shift sleeves, that with a first partial transmission and a second partial transmission cooperates the said shift transmission influenced double clutch, is that each partial transmission has control elements through Switching actuators are formed. To the transmission or the manual transmission with the sliding sleeves in connection with these control elements to operate properly suited to this purpose is suitable Method.
Darüber hinaus setzt das Getriebe, das als Schaltmuffen aufweisendes Schaltgetriebe ausgebildet ist und mit einer mehrerer 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.Furthermore sets the gearbox, the gearshift having gearboxes is formed and having a plurality of couplings preferably cooperates as a double clutch clutch device shown Both in terms of use of components and impact standards. For this inter alia bear the control elements for moving the sliding sleeves and the clutch pressure regulator at.
