Description

Beschreibung description
Aktuator actuator
Gegenstand der Erfindung ist ein Aktuator mit einem Stellglied, welches in einem Gehäuse gelagert ist, einem Elektromotor zum Antrieb des Stellgliedes, einem aus mindestens einem Zwischenrad bestehenden Getriebe, wobei zumindest das Zwischenrad auf einer Welle angeordnet und die Welle im Gehäuse gelagert ist und einem das Getriebe verschließenden Deckel. The invention relates to an actuator with an actuator which is mounted in a housing, an electric motor for driving the actuator, consisting of at least one intermediate gear, wherein at least the intermediate arranged on a shaft and the shaft is mounted in the housing and a Gear closing lid.
Solche Aktuatoren werden in Kraftfahrzeugen eingesetzt und sind somit bekannt. Das Stellglied kann Stößel sein, der eine Li nearbewegung ausführt. Es sind aber auch Aktuatoren bekannt, bei denen das Stellglied eine drehbar auf einer Welle gelagerte Klappe ist, die beispielsweise den Durchfluss eines Mediums in einem Kanal regelt. Die Stellglieder werden von dem Elektromotor angetrieben. Um die Drehzahl des Elektromotors an die Bewegung des Stellglieds anzupassen, ist ein Getriebe zwischengeschaltet. Je nach gewünschter Übersetzung oder Umwandlung der Drehbewegung des Ritzels vom Elektromotor in eine translatorische Bewegung weist das Getriebe ein oder mehrere Zahnräder als Zwischenräder auf. Diese Zwischenräder bestehen größtenteils aus Kunststoff und sind auf Wellen gelagert, die wiederum aus Metall bestehen. Die Herstellung solcher Aktuatoren ist aufgrund der Vielzahl von Bauteilen relativ aufwendig. Insbesondere für das Getriebe müssen die Zwischenräder und die entsprechenden Wellen ge fertigt, vormontiert und im Aktuator verbaut werden. Dabei umfasst die Herstellung der Wellen mit Herstellung, Reinigung, Transport, sowie das Vorsehen verschiedenster Hilfsstoffe eine Vielzahl von Arbeitsschritten. Such actuators are used in motor vehicles and are thus known. The actuator may be tappets that performs a Li nearbewegung. But there are also actuators known in which the actuator is a rotatably mounted on a shaft flap, which controls, for example, the flow of a medium in a channel. The actuators are driven by the electric motor. To adjust the speed of the electric motor to the movement of the actuator, a transmission is interposed. Depending on the desired ratio or conversion of the rotational movement of the pinion from the electric motor in a translational movement, the transmission has one or more gears as intermediate wheels. These intermediate wheels are largely made of plastic and are mounted on shafts, which in turn consist of metal. The production of such actuators is relatively expensive due to the large number of components. In particular, for the transmission, the intermediate wheels and the corresponding shafts must be made ge, pre-assembled and installed in the actuator. In this case, the production of shafts with production, cleaning, transport, as well as the provision of various auxiliaries includes a variety of steps.
Der Erfindung liegt daher die Aufgabe zugrunde einen Aktuator zu schaffen, der in der Herstellung einfacher ist, ohne dass die Zuverlässigkeit beeinträchtigt wird. Gelöst wird die Aufgabe dadurch, dass mindestens eine Welle des Getriebes einteilig mit einem anderen Bauteil des Aktuators hergestellt ist. Mit der einteiligen Fertigung mindestens einer Welle des Getriebes mit einem anderen Bauteil des Aktuators lässt sich die Herstellung de Aktuators wesentlich vereinfachen. Alle separaten Arbeitsschritte zur Herstellung der Welle, sowie deren Handhabung und Montage mit den Zahnrädern können mit dem er findungsgemäßen Aktuator entfallen. The invention is therefore based on the object to provide an actuator which is simpler to manufacture, without the reliability is impaired. The object is achieved in that at least one shaft of the transmission is made in one piece with another component of the actuator. With the one-piece production of at least one shaft of the transmission with another component of the actuator, the production of the actuator can be substantially simplified. All separate steps for the production of the shaft, as well as their handling and assembly with the gears can account for he inventive actuator.
In einer besonders vorteilhaften Ausgestaltung ist die min destens eine Welle einteilig mit einem Zwischenrad gefertigt ist . Der Vorteil besteht darin, dass durch die einteilige Fertigung bereits ein fester Verbund zwischen Welle und Zwischenrad existiert. Früher musste sowohl Welle als auch Zwischenrad sehr exakt hinsichtlich des Sitzes und der damit einzuhaltenen Toleranzen gefertigt werden. Mit der erfindungsgemäßen ein teiligen Ausbildung entfällt diese Forderung. Das Verbundbauteil kann somit deutlich einfacher und kostengünstiger gefertigt werden. Unter einem Zwischenrad wird im Sinne der Erfindung ein Zahnrad oder ein Zahnradsegment verstanden. In a particularly advantageous embodiment, the min least one shaft is made in one piece with an intermediate. The advantage is that the one-piece production already exists a solid bond between the shaft and idler. Previously, both the shaft and the idler had to be manufactured very precisely with respect to the seat and the tolerances to be adhered to. With the inventive one-piece training eliminates this requirement. The composite component can thus be made much easier and cheaper. Under an intermediate gear is understood in the context of the invention, a gear or a gear segment.
Eine deutliche Vereinfachung bei der Herstellung der mindestens einen Welle wird dadurch erreicht, wenn diese durch Spritzgießen von Kunststoff mit dem anderen Bauteil des Aktuators hergestellt ist. Es hat sich überraschend gezeigt, dass die Verwendung von Kunststoff als Wellenmaterial ausreichend ist. Eine solche Welle muss für eine vergleichbare Festigkeit zwar größer dimensioniert werden, allerdings erlaubt die Verwendung von Kunststoff eine Gewichtsreduktion des Aktuators. A significant simplification in the production of at least one shaft is achieved when this is made by injection molding of plastic with the other component of the actuator. It has surprisingly been found that the use of plastic as a shaft material is sufficient. Although such a shaft must be dimensioned larger for comparable strength, the use of plastic allows weight reduction of the actuator.
Für eine sichere und langzeitstabile Lagerung der mindestens einen Welle hat es sich als vorteilhaft herausgestellt, die mindestens eine Welle im Gehäuse zu lagern. Je nach Anwendung und Belastungsfall lässt sich im Gehäuse eine dementsprechende Lagerstelle vorsehen, in der die Welle gelagert ist. Größere Wellenabmaße, bedingt durch den Ersatz von Metall durch Kunststoff, lassen sich deutlich reduzieren, wenn die mindestens eine Welle aus glasfaserverstärktem Kunststoff, vorzugsweise glasfaserverstärktem Polybutylenterephthalat (PBT) gefertigt ist. Diese Kunststoffe besitzen eine erhöhte Festigkeit, so dass deren Verwendung das Gewicht des Aktuators weiter reduziert. For a safe and long-term stable storage of at least one shaft, it has been found to be advantageous to store the at least one shaft in the housing. Depending on the application and load case can be provided in the housing a corresponding bearing point in which the shaft is mounted. Larger shaft dimensions, due to the replacement of metal by plastic, can be significantly reduced if the at least one shaft made of glass fiber reinforced plastic, preferably glass fiber reinforced polybutylene terephthalate (PBT) is made. These plastics have increased strength so that their use further reduces the weight of the actuator.
Die Fertigung der mindestens einen Welle mit einem anderen Bauteil bedeutet, dass zwei Bauteile mit unterschiedlichen Funktionen einteilig hergestellt werden. Dabei werden an jedes Bauteil unterschiedliche Anforderungen hinsichtlich der The manufacture of the at least one shaft with another component means that two components with different functions are produced in one piece. In this case, each component has different requirements in terms of
Werkstoffeigenschaften gestellt. Beeinträchtigungen in der Funktion eines oder beider Bauteile durch eine entsprechende Werkstoffauswahl lassen sich gemäß einer vorteilhaften Aus gestaltung dadurch vermeiden, dass die mindestens eine Welle aus einem anderen Kunststoff als das andere Bauteil, mit dem sie einteilig gefertigt ist, besteht. In besonders einfacher Weise erfolgt die Fertigung im Zwei-Komponenten-Spritzgießverfahren . Bei diesem Verfahren werden zwei unterschiedliche Kunststoffe in einem Spritzgießvorgang verarbeitet, wobei am Ende des Material properties provided. Impairments in the function of one or both components by an appropriate choice of materials can be avoided in accordance with an advantageous embodiment in that the at least one shaft made of a different plastic than the other component with which it is made in one piece. In a particularly simple manner, the production takes place in two-component injection molding. In this process, two different plastics are processed in an injection molding process, at the end of the
Spritzgießvorgangs ein fertiges Bauteil erzeugt wurde. Injection molding a finished component was produced.
Zur weiteren Vereinfachung bei der Herstellung des erfin dungsgemäßen Aktuators trägt es bei, wenn die mindestens eine Welle nicht nur mit einem, sondern mit zwei Zwischenrädern einteilig ausgebildet. For further simplification in the production of the inventions to the invention actuator, it helps if the at least one shaft formed integrally not only with one, but with two intermediate wheels.
In einer anderen Ausgestaltung ist es aber auch möglich ein zweites Zwischenrad zusätzlich zu dem ersten Zwischenrad zu montieren, wobei die mindestens eine Welle einen Sitz für ein Zahnrad aufweist.  In another embodiment, however, it is also possible to mount a second intermediate gear in addition to the first intermediate gear, wherein the at least one shaft has a seat for a gear.
An einem Ausführungsbeispiel wird die Erfindung näher be schrieben. Es zeigt in In one embodiment, the invention will be described in more detail be. It shows in
Fig. 1 eine Schnittdarstellung eines Aktuators nach dem Stand der Technik und Fig. 2 eine vergrößerte Darstellung der erfindungsgemäßen Welle . Fig. 1 is a sectional view of an actuator according to the prior art and Fig. 2 is an enlarged view of the shaft according to the invention.
Der Aktuator in Figur 1 ist ein Drosselklappenstutzen 1 im Ansaugtrakt eines Kraftfahrzeugs. In einem Metallgehäuse 2 befindet sich ein Strömungskanal 3, über den Luft dem Ver brennungsmotor des Kraftfahrzeugs zugeführt wird. Eine in dem Stömungskanal 3 drehbar auf einer Welle 4 angeordnete Klappe 5 erlaubt eine Regelung der Luftzufuhr. Die Welle 4 ist im Gehäuse 2 gelagert und ragt bis in eine Getriebekammer 6. Das dortige Ende der Welle 4 ist mit einem Zahnrad 7 verbunden. Über zwei Zwischenräder 8 ist das Zahnrad 7 mit einem Ritzel 9 des Elektromotors 10 verbunden, so dass durch Ansteuerung des Elektromotors 10 die Klappe 5 entsprechend verdreht werden kann. Die Getriebekammer 6 ist mit einem Deckel 11 verschlossen. The actuator in Figure 1 is a throttle body 1 in the intake of a motor vehicle. In a metal housing 2 is a flow channel 3, is supplied via the air to the United combustion engine of the motor vehicle. A valve 5 rotatably arranged in the flow channel 3 on a shaft 4 allows a control of the air supply. The shaft 4 is mounted in the housing 2 and extends into a gear chamber 6. The local end of the shaft 4 is connected to a gear 7. About two intermediate wheels 8, the gear 7 is connected to a pinion 9 of the electric motor 10, so that by driving the electric motor 10, the flap 5 can be rotated accordingly. The gear chamber 6 is closed by a lid 11.
Figur 2 zeigt die erfindungsgemäße Welle 12 aus einem glas faserverstärktem Kunststoff. Die Welle besitzt ein erstes Ende 13, welches im Gehäuse 2 gelagert ist. Die Welle 13 ist einteilig mit einem Zahnrad 14 mittels Spritzgießen hergestellt. Das Zahnrad 14 besitzt einen scheibenförmigen Grundkörper 15, der auf einer Seite durch ebenfalls einteilig angeformte Rippen 16 verstärkt ist, um so eine größere Festigkeit des Zahnrades zu erzielen. Radial außen ist am Grundkörper 15 der umlaufende Zahnkranz 17 ausgebildet. Die Welle 12 besitzt einen Bereich 18 mit vergrößertem Durchmesser. Dieser Bereich 18 ist besitzt ebenfalls eine Verzahnung und ist ein weiteres Zahnrad für den Einsatz in einem Getriebe. Figure 2 shows the shaft 12 of the invention from a glass fiber reinforced plastic. The shaft has a first end 13, which is mounted in the housing 2. The shaft 13 is made in one piece with a gear 14 by means of injection molding. The gear 14 has a disk-shaped base body 15 which is reinforced on one side by integrally molded ribs 16 so as to achieve a greater strength of the gear. Radially on the outside of the main body 15 of the peripheral ring gear 17 is formed. The shaft 12 has a region 18 of increased diameter. This area 18 also has a toothing and is another gear for use in a transmission.
