Description
Die Erfindung betrifft eine Drosselklappenvorrichtung für einen Verbrennungsmotor in einem Hybridantriebsstrang eines Kraftfahrzeuges, insbesondere für einen Range-Extender, mit einem Gehäuse, in dessen Inneren ein durchströmter Fluidkanal ausgebildet ist, mit einem Klappenkörper, der den durchströmbaren Querschnitt des Kanals bestimmt, mit einer Klappenwelle, auf der der Klappenkörper angeordnet ist und die drehbar im Gehäuse an mindestens einer Lagerstelle gelagert ist, mit einer Stelleinheit, die die Klappenwelle antreibt.The invention relates to a throttle valve device for an internal combustion engine in a hybrid drive train of a motor vehicle, in particular for a range extender, with a housing, in the interior of which a fluid channel is formed, with a flap body, which determines the flow-through cross section of the channel, with a flap shaft, on which the flap body is arranged and which is rotatably mounted in the housing at at least one bearing point, with an actuating unit which drives the flap shaft.
Drosselklappenvorrichtungen für einen Verbrennungsmotor sind hinlänglich bekannt. Hierbei hat die Drosselklappe das Ziel, die Luftmenge für den Verbrennungsmotor zu steuern, um gemeinsam mit einer zu steuernden Treibstoffmenge die geforderte Abgabeleistung zu regulieren. So ist insbesondere aus der
In den vergangenen Jahren haben Hybridfahrzeuge immer mehr Beachtung gefunden. Standen zunächst Kohlenwasserstoffe als Primärenergie (und damit der Verbrennungsmotor) im Vordergrund, so gewinnt in der jüngeren Vergangenheit die Verwendung von elektrischer Energie als Primärenergie einen immer größeren Stellenwert, wobei ein kleiner einfach ausgelegter Verbrennungsmotor lediglich noch als Reichweitenverlängerer, Range-Extender, eingesetzt wird. Insbesondere vor dem Hintergrund des Einsatzes von zwei Motorenkonzepten in ein Kraftfahrzeug ist die Bauraum- und Kostenoptimierung sehr wichtig. Bestehende Drosselklappenvorrichtungen sind für einen derartigen Verbrennungsmotor überdimensioniert.In recent years, hybrid vehicles have gained more and more attention. Initially, hydrocarbons were the primary energy (and thus the combustion engine) in the foreground, so in the recent past, the use of electrical energy as a primary energy is gaining ever greater importance, with a small simply designed internal combustion engine is only used as Range Extender, Range Extender. In particular, against the background of the use of two engine concepts in a motor vehicle, the space and cost optimization is very important. Existing throttle devices are oversized for such an internal combustion engine.
Aufgabe der vorliegenden Erfindung ist es daher, eine Drosselklappenvorrichtung zu schaffen, die insbesondere geeignet ist für einen Hybridantriebsstrang eines Kraftfahrzeuges und dabei insbesondere für einen seriellen Range-Extender.Object of the present invention is therefore to provide a throttle valve device which is particularly suitable for a hybrid powertrain of a motor vehicle and in particular for a serial range extender.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Stelleinheit eine begrenzte Anzahl von Stellpositionen für den Klappenkörper vorsieht. Auf diese Weise wird eine Drosselklappenvorrichtung geschaffen, deren Stelleinrichtung lediglich sicherstellen muss, dass die Drosselklappe zwischen einer begrenzten Anzahl von Stellpositionen verstellbar ist. Beispielsweise können hier drei vordefinierte Stellpositionen gewählt werden: 1. Lastpunkt 25 kW, 2. Lastpunkt 15 kW und 3. Lastpunkt 10 kW. Eine aufwendige Positionsregelung kann hierdurch entfallen. Auch ist ein Elektromotor der Stelleinheit wesentlich einfacher auszuführen. Besonders vorteilhaft ist eine Ausführungsform, bei der die Stelleinheit eine Einrastvorrichtung mit Einrastpositionen aufweist. Hierdurch kann die Stelleinheit noch einfacher und günstiger ausgeführt werden. Vorteilhafterweise weist die Stelleinheit einen Elektromotor und ein Getriebe auf, wobei ein Getriebeausgang drehfest mit der Klappenwelle verbunden ist. Hierbei kann das Getriebe als Schneckengetriebe ausgebildet sein, wobei ein Schneckenzahnrad des Schneckengetriebes drehfest mit der Klappenwelle verbunden ist. Als besonders vorteilhaft hat es sich erwiesen, wenn die Stelleinheit, und hierbei beispielsweise das Schneckenzahnrad, Einrastorgane aufweist, die im Zusammenwirken mit einem Federorgan ein Einrasten in die gewünschten Einrastpositionen ermöglichen.This object is achieved in that the actuator provides a limited number of parking positions for the valve body. In this way, a throttle valve device is provided, the adjusting device only has to ensure that the throttle valve between a limited number of parking positions is adjustable. For example, three predefined setting positions can be selected here: 1. load point 25 kW, 2. load point 15 kW and 3.
Aus montagetechnischer Sicht ist es sinnvoll, wenn das Gehäuse den Fluidkanal und ein Basisgehäuseteil für die Stelleinheit, das durch ein Deckelteil verschließbar ist, aufweist. Hierdurch entfällt die aufwendige Montage und Ausrichtung des Basisgehäuseteils der Stelleinheit am Drosselklappengehäuse. Ein derartiges Gehäuse kann vorteilhafterweise aus Kunststoff hergestellt sein.From a technical point of view, it makes sense if the housing has the fluid channel and a base housing part for the actuating unit, which can be closed by a cover part. This eliminates the costly assembly and alignment of the base housing part of the actuator on the throttle body. Such a housing may advantageously be made of plastic.
Um die Position des Klappenkörpers auf einfache Weise detektieren zu können, kann die Stelleinheit eine berührungslose Sensorvorrichtung aufweisen.In order to be able to detect the position of the flap body in a simple manner, the setting unit can have a contactless sensor device.
Nachfolgend wird die Erfindung anhand der Zeichnungen näher erläutert. Hierbei zeigt:The invention will be explained in more detail with reference to the drawings. Hereby shows:
