Abstract
Description
Die Erfindung betrifft einen ein Getriebe und ein Antriebsaggregat umfassenden Antriebsstrang eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1.The The invention relates to a transmission and a drive unit comprehensive Drive train of a motor vehicle according to the preamble of the claim 1.
Die Hauptkomponenten eines Antriebsstrangs eines Kraftfahrzeugs sind ein Antriebsaggregat und ein Getriebe. Ein Getriebe wandelt Drehmomente und Drehzahlen und setzt so das Zugkraftangebot des Antriebsaggregats um. Die hier vorliegende Erfindung betrifft einen Antriebsstrang, der zumindest ein Getriebe und als Antriebsaggregat vorzugsweise einen Hybridantrieb mit einem Verbrennungsmotor und einem Elektromotor umfasst.The Main components of a drive train of a motor vehicle are a drive unit and a transmission. A gearbox converts torques and speeds and thus sets the traction power supply of the drive unit around. The present invention relates to a drive train, the at least one transmission and as a drive unit preferably a hybrid drive with an internal combustion engine and an electric motor includes.
Bei einem Antriebsstrang mit einem Hybridantrieb ist der Verbrennungsmotor zur Reduzierung des Kraftfstoffverbrauchs sowie zur Reduzierung von Emissionen über große Teile der Betriebszeit abgeschaltet, wobei der Verbrennungsmotor nur dann zugeschaltet wird, wenn die vom Elektromotor bereitgestellte Leistung nicht ausreicht. Daraus folgt zwangsläufig, dass Verbrennungsmotoren in einem Hybridantrieb-Antriebsstrang eine deutlich höhere Anzahl von Starts ausführen müssen als in einem konventionellen Antriebsstrang, der lediglich einen Verbrennungsmotor umfasst. Der Start eines Verbrennungsmotors belastet, aufgrund der fehlenden Motorschmierung, motorinterne Baugruppen, so z. B. eine Kurbelwelle, eine Nockenwelle, Pleuellager und Kolbenlager, wodurch dieselben einem erhöhten Verschleiß ausgesetzt sind. Eine Hydraulikpumpe des Verbrennungsmotors kann nämlich nur dann eine ausreichende Motorschmierung gewährleisten, wenn der Verbrennungsmotor eine Mindestdrehzahl erreicht hat. Beim Start des Verbrennungsmotors hingegen kann die Hydraulikpumpe desselben aufgrund der geringen Drehzahl des Verbrennungsmotors noch keine ausreichende Motorschmierung gewährleisten.at a powertrain with a hybrid drive is the internal combustion engine to reduce fuel consumption and reduce fuel consumption of emissions over much of the operating time switched off, with the internal combustion engine only switched on when the power provided by the electric motor is insufficient. It necessarily follows that internal combustion engines in a hybrid drive powertrain a much higher Number of starts must run as in one conventional powertrain, the only one internal combustion engine includes. The start of an internal combustion engine loaded, due to missing engine lubrication, engine-internal components, such. B. a crankshaft, a camshaft, connecting rod bearing and piston bearing, whereby the same are exposed to increased wear. A Hydraulic pump of the internal combustion engine can namely only then ensure sufficient engine lubrication, if the Internal combustion engine has reached a minimum speed. At the start the internal combustion engine, however, the same can the hydraulic pump due to the low speed of the engine still no ensure sufficient engine lubrication.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, einen neuartigen, weniger verschleißgefährdeten Antriebsstrang zu schaffen. Dieses Problem wird durch einen Antriebsstrang gemäß Anspruch 1 gelöst. Erfindungsgemäß unterstützt ein Hydrauliksystem zumindest während des Starts des Verbrennungsmotors einen Hydraulikdruckaufbau einer Hydraulikpumpe des Verbrennungsmotors. Beim erfindungsgemäßen Antriebsstrang unterstützt ein Hydrauliksystem zumindest während des Starts des Verbrennungsmotors die Hydraulikpumpe des Verbrennungsmotors beim Aufbau des Hydraulikdrucks, um so auch beim Start des Verbrennungsmotors eine gute Motorschmierung zu gewährleisten. Hierdurch kann ein vorzeitiger Verschleiß motorinterner Baugruppen des Verbrennungsmotors reduziert werden.Of these, Based on the present invention, the problem underlying a novel, less susceptible to wear To create a powertrain. This problem is caused by a powertrain solved according to claim 1. Supported according to the invention a hydraulic system at least during the start of the internal combustion engine a hydraulic pressure buildup of a hydraulic pump of the internal combustion engine. Supported in the drive train according to the invention a hydraulic system at least during the start of the internal combustion engine the hydraulic pump of the internal combustion engine when building up the hydraulic pressure, so also at the start of the engine good engine lubrication to ensure. This can cause premature wear inside the engine Assemblies of the internal combustion engine can be reduced.
