Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Betätigen zweier Kupplungen gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a device for actuating two clutches according to the preamble of patent claim 1.

Durch die DE 195 04 847 A1 oder der DE 198 32 015 A1 sind Vorrichtungen zur Betätigung eines Elementes im Antriebsstrang eines Kraftfahrzeuges der Anmelderin bekannt geworden. Diese Vorrichtungen betätigen beispielsweise Reibungskupplungen im Antriebsstrang von Kraftfahrzeugen. Diese weisen jeweils einen Elektromotor, ein Getriebe und eine Elektronikeinheit auf. Bei Verwendung zweier Aktuatoren zur Betätigung zweier Kupplungen eines Getriebes wird bei den bekannten Aktuatoren sehr viel Bauraum benötigt und zusätzlich dazu ein wesentlich größerer Verkabelungsaufwand nötig sein.By the DE 195 04 847 A1 or the DE 198 32 015 A1 Devices have become known for actuating an element in the drive train of a motor vehicle of the applicant. These devices operate, for example, friction clutches in the drive train of motor vehicles. These each have an electric motor, a transmission and an electronics unit. When using two actuators to actuate two clutches of a transmission much space is required in the known actuators and in addition a much larger cabling effort may be necessary.

Ferner offenbart die DE 198 59 458 A1 eine Vorrichtung zum Betätigen zweier Kupplungen gemäß dem Oberbegriff des Patentanspruchs 1, wobei zwei separate Aktuatoren vorgesehen sind.Further, the DE 198 59 458 A1 a device for actuating two clutches according to the preamble of patent claim 1, wherein two separate actuators are provided.

Die vorliegende Erfindung hat zur Aufgabe eine Vorrichtung zum Betätigen zu schaffen, die gegenüber dem Stand der Technik bauraumsparend und einfach aufgebaut ist. Weiterhin sollte der Verkabelungsaufwand minimal sein.The present invention has for its object to provide a device for actuating, which is space-saving and simple compared to the prior art. Furthermore, the cabling effort should be minimal.

Erfindungsgemäß gelöst wird diese Aufgabe durch eine Vorrichtung zum Betätigen zweier Kupplungen gemäß Patentanspruch 1.This object is achieved according to the invention by a device for actuating two clutches according to patent claim 1.

Dabei ist es vorteilhaft, wenn zumindest eine der Kupplungen als Trockenreibungskupplung ausgebildet ist.It is advantageous if at least one of the clutches is designed as a dry friction clutch.

Die Erfindung wird im Folgenden anhand einer schematischen Zeichnung beispielsweise und mit weiteren Einzelheiten erläutert. Dabei zeigt die 1 eine schematische Darstellung der Erfindung.The invention will be explained below with reference to a schematic drawing, for example, and with further details. It shows the 1 a schematic representation of the invention.

Die 1 zeigt eine erfindungsgemäße Vorrichtung 1 mit einem Getriebe 2 mit Getriebeausgangswelle 7 im Antriebsstrang eines Kraftfahrzeuges mit einem Antriebsmotor 6.The 1 shows a device according to the invention 1 with a gear 2 with transmission output shaft 7 in the drive train of a motor vehicle with a drive motor 6 ,

Das Getriebe 2 ist als Getriebe mit zumindest zwei Kupplungen aufgebaut, wie beispielsweise Doppelkupplungsgetriebe mit zwei Getriebeeingangswellen 8, 9 oder wie ein Lastschaltgetriebe mit einer Anfahrkupplung und einer Lastschaltkupplung. Die zumindest beiden Kupplungen können als zumindest zwei Kupplungen, wie beispielsweise Anfahrkupplung und Lastschaltkupplung ausgebildet sein oder als in einem Kupplungsaggregat zusammengefasste Doppelkupplung aufgebaut sein. Dabei können je nach Anwendungsfall auch Getriebe mit drei oder mehr Kupplungen vorgesehen sein und von dem Aktuator betätigt werden.The gear 2 is constructed as a transmission with at least two clutches, such as dual-clutch transmission with two transmission input shafts 8th . 9 or as a power shift transmission with a starting clutch and a power-shift clutch. The at least two clutches can be designed as at least two clutches, such as starting clutch and power shift clutch or constructed as a combined in a clutch unit double clutch. Depending on the application, transmissions with three or more clutches can also be provided and actuated by the actuator.

Doppelkupplungsgetriebe sind beispielsweise durch die DE 197 11 820 A1 bekannt geworden.Double clutch transmissions are for example by the DE 197 11 820 A1 known.

Lastschaltgetriebe sind beispielsweise durch die WO 99/33682 A2 bekannt geworden. Die vorliegende Erfindung betrifft weiterhin die WO 99/33682 A2 , die hiermit ausdrücklich zum Offenbarungsgehalt der vorliegenden Patentanmeldung gehört.Power shift are, for example, by the WO 99/33682 A2 known. The present invention further relates to WO 99/33682 A2 , which hereby expressly belongs to the disclosure content of the present patent application.

Zur Betätigung der beiden Kupplungen 8, 9 des Getriebes ist ein Aktuator 10 vorgesehen, der als Baueinheit die beiden Elektromotoren 11, 12, die Getriebe 13, 14 und die Elektronikeinheit 15 mit Anschluss 16 aufweist. Vorteilhaft ist es, wenn eine gemeinsame Steuer- und Leistungselektronik zur Ansteuerung der Elektromotoren 11, 12 in dem Aktuator 10 verwendet wird.For actuating the two clutches 8th . 9 the gearbox is an actuator 10 provided, as a unit, the two electric motors 11 . 12 , the gears 13 . 14 and the electronics unit 15 with connection 16 having. It is advantageous if a common control and power electronics for controlling the electric motors 11 . 12 in the actuator 10 is used.

Die Getriebe 13 und 14 sind eingangsseitig mit den Elektromotoren 11, 12 verbunden. Ihre Ausgangselemente 21, 22 stehen über jeweils eine Hydraulikverbindung 23, 24 mit zwei Ausrücklagern 31, 32 in Verbindung. Dadurch können die beiden Kupplungen 4, 5 unabhängig von einander betätigt werden.The gears 13 and 14 are input side with the electric motors 11 . 12 connected. Your starting elements 21 . 22 each have a hydraulic connection 23 . 24 with two release bearings 31 . 32 in connection. This allows the two clutches 4 . 5 be operated independently of each other.

An der Kurbelwelle des Motors ist vorteilhaft ein Zweimassenschwungrad (ZMS) 3 vorgesehen, das die beiden Kupplungen trägt.At the crankshaft of the engine is advantageously a dual mass flywheel (ZMS) 3 provided, which carries the two clutches.

Der Aktuator 10 weist zumindest zwei Antriebe, wie Elektromotoren 11, 12 auf, welche in Abhängigkeit der zu betätigenden Kupplungen 8, 9 gleich oder unterschiedlich in ihrer Leistungsfähigkeit, Drehmoment und Leistungsaufnahme ausgebildet sein können.The actuator 10 has at least two drives, such as electric motors 11 . 12 on, which depends on the actuated clutches 8th . 9 may be the same or different in their performance, torque and power consumption.
