Beschreibungdescription
Die Erfindung betrifft eine Drosseleinrichtung nach dem Oberbegriff des Hauptanspruchs.The invention relates to a throttle device according to the preamble of the main claim.
Eine Drosselklappe ist beispielsweise aus der EP 04 98 933 A1 bekannt. Diese ist in ein Gehäuse integriert, welches an einem Trägerkörper befestigt werden kann. Das Gehäuse ist nach Art eines Drosselklappenstutzens ausgebildet, d. h. der Stutzen ist einerseits an dem Trägerkörper und andererseits an der Sauganlage einer Brennkraftmaschine befestigt.A throttle valve is known for example from EP 04 98 933 A1. This is integrated in a housing that can be attached to a carrier body. The housing is designed in the manner of a throttle valve assembly, i. H. the connection piece is fastened on the one hand to the carrier body and on the other hand to the intake system of an internal combustion engine.
Ein Nachteil dieser Drossel kl appenbefestigung ist darin zu sehen, daß ein hoher Bauteileaufwand erforderlich ist sowie eine größere Anzahl von Abdichtelementen zwischen den einzelnen Bauteilen nötig wird.A disadvantage of this throttle kl appenbefestigung can be seen in the fact that a high amount of components is required and a larger number of sealing elements between the individual components is necessary.
Es ist weiterhin aus der WO 91 05 152 einer Drosseleinrichtung zum Reduzieren der Gaswechsel Verluste bei einer Brennkraftmaschine bekannt. Auch diese Drosseleinrichtung ist ein separates Bauteil, welches einerseits an den Ansaugtrakt eines Motors und andererseits an ein luftführendes System angeschlossen werden muß.It is also known from WO 91 05 152 a throttle device for reducing the gas exchange losses in an internal combustion engine. This throttle device is also a separate component which, on the one hand, must be connected to the intake tract of an engine and, on the other hand, to an air-guiding system.
Ein Nachteil dieser bekannten Einrichtung ist der hohe Montageaufwand sowie die große Anzahl von Einzelteilen, welche bei der Montage der Drosseleinrichtung zu einer Einheit zusammengefügt werden müssen. Dagegen ist im Zuge der fortwährenden Reduzierung von Bauteilen und der Optimierung sowie Gewichtsreduzierung im Fahrzeug- und Automobilbau das Bestreben zu erkennen, Komplettsysteme herzustellen, die dieses Ziel verwirkl ichen .A disadvantage of this known device is the high Assembly effort and the large number of individual parts, which must be assembled into a unit when assembling the throttle device. On the other hand, in the course of the continuous reduction of components and the optimization and weight reduction in vehicle and automobile construction, the endeavor can be recognized to produce complete systems that achieve this goal.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Drosseleinrichtung zu schaffen, die einen geringen Montageaufwand erfordert und die Wartung des Systems vereinfacht. Diese Aufgabe wird ausgehend von dem Oberbegriff des Hauptanspruchs durch dessen kennzeichnenden Merkmale gelöst.The invention is therefore based on the object of providing a throttle device which requires little assembly effort and simplifies the maintenance of the system. This object is achieved on the basis of the preamble of the main claim by its characterizing features.
Ein wesentlicher Vorteil der Erfindung ist darin zu sehen, daß die konsequente Anwendung von Kunststoff im Bereich des Ansaugtrakts einer Brennkraftmaschine weitgehend berücksichtigt ist. Gerade Kunststoff bewirkt wegen des geringeren Elastizitätsmoduls zum Teil wesentlich geringere spezifische Werkstoffbeanspruchungen durch die infolge Verformung stark vergrößerte Auflagefl che als bei Stahlpaarungen. Außerdem hat Kunststoff weitere interessante Eigenschaften, z. B. Korrosionsbeständigkeit, die hohe mechanische Dämpfung, einen äußerst geringen Reibungskoeffizienten, geringeren Verschleiß, niedriges spezifisches Gewicht, gute Verarbeitbarkeit und niedrige Fertigteilkosten bei Massenfertigungen. Besonders die letztgenannte Eignung der Kunststoffe zur kostengünstigen Endfertigung, die am bestechendsten beim Spritzgießen kompliziert gestalteter Teile auffällt, macht sie im Vergleich zu anderen Werkstoffen überlegen.An important advantage of the invention is that the consistent use of plastic in the intake tract of an internal combustion engine is largely taken into account. Plastic in particular, due to the lower modulus of elasticity, sometimes results in significantly lower specific material stresses due to the greatly increased contact surface as a result of deformation than with steel pairings. Plastic also has other interesting properties, e.g. B. corrosion resistance, the high mechanical damping, an extremely low coefficient of friction, less wear, low specific weight, good workability and low finished part costs in mass production. In particular, the latter suitability of plastics for cost-effective finishing, which is most striking in injection molding of complicated parts, makes them superior to other materials.
Bisher bekannte Drosselklappen bzw. Drosseleinrichtungen waren üblicherweise in Metall ausgeführt und zwischen einem Kunststoff-Luftfilter und einer Kunststoff-Sauganl age angeordnet Durch den modulartigen Aufbau der Drosselklappe läßt sich derPreviously known throttle valves or throttle devices were usually made of metal and arranged between a plastic air filter and a plastic suction system. The modular design of the throttle valve allows the
ORIGINAL UNTERLAGEN Montageaufwand erheblich reduzieren. Außerdem ermöglicht die Modulbauweise einen einfachen Austausch defekter Teile und eine Baugruppenfertigung, bei der, ausgehend von einem Grundmodul, unterschiedliche Komponenten je nach Anforderung miteinander zu einer Drosseleinrichtung kombiniert werden können.ORIGINAL DOCUMENTS Reduce assembly effort considerably. In addition, the modular design enables simple replacement of defective parts and assembly production, in which, starting from a basic module, different components can be combined to form a throttle device, depending on the requirements.
Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, die Drosselklappe mit einer zweigeteilten Welle zu versehen. Dies hat den Vorteil, daß neben einer Montageerleichterung auch zwei getrennte Module auf den Wellenteilen vorhanden sein können. Es bietet sich an, auf einem Wellenteil den Stellungssensor und auf dem weiteren Wellenteil die Stelleinheit anzuordnen.An advantageous embodiment of the invention provides for the throttle valve to be provided with a two-part shaft. This has the advantage that, in addition to facilitating assembly, two separate modules can also be present on the shaft parts. It is advisable to arrange the position sensor on one shaft part and the actuating unit on the other shaft part.
Eine weitere Ausgestaltung der Erfindung sieht vor, das Drosselklappenmodul als Gesamteinheit in einen vorhandenenA further embodiment of the invention provides that the throttle valve module as an overall unit in an existing one
Anschlußstutzen einzuschieben oder zwischen zwei Anschlußstutzen einzubinden. So wird ein zusätzlicher Drosselklappenstutzen vermieden .Insert the connecting piece or integrate it between two connecting pieces. An additional throttle body is avoided.
Nach einer weiteren Ausgestaltung der Erfindung ist es zweckmäßig, das Gehäuse des Drosselklappenmoduls in einen Anschluß zu integrieren. Dies bedeutet, daß das Verbindungselement zwischen einem Luftfilterausgang und einem Sauganlageneingang gleichzeitig das Drosselklappenmodul darstellt.According to a further embodiment of the invention, it is expedient to integrate the housing of the throttle valve module into a connection. This means that the connecting element between an air filter outlet and a suction system inlet simultaneously represents the throttle valve module.
Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.These and further features of preferred developments of the invention are evident from the claims and also from the description and the drawings, the individual features being implemented individually or in groups in the form of subcombinations in the embodiment of the invention and in other fields, and can represent advantageous and protectable versions for which protection is claimed here.

Auf der gegenüberliegenden Seite der Ansteuerseite für die Drosselklappe befindet sich die Befestigungseinrichtung 21 für den Bowdenzug, eine Rückstellfeder 22 sowie die hier nicht sichtbare weitere Halbwelle. Vor der Montage dieser beiden Module wird die Drosselklappe in den Drosselklappenstutzen 18 eingefügt und durch das Montieren der beiden Module auf den Halbwellen fixiert.In Figure 2, a throttle valve module with split throttle shafts is shown. A throttle flap nozzle 18, which is connected to a suction system, not shown here, by means of suitable screw connections, consists of a plastic injection molded part 1. A preassembled module 19, which contains position sensors and further measuring devices and a half-shaft 20, is attached to this. On the opposite side of the control side for the throttle valve there is the fastening device 21 for the Bowden cable, a return spring 22 and the further half-wave (not visible here). Before the assembly of these two modules, the throttle valve is inserted into the throttle valve connector 18 and fixed on the half-shafts by mounting the two modules.
Ein Vorteil dieses Drosselklappensteckmodul s ist darin zu sehen, daß die einzelnen Module, wie z. B. das Modul 19, einfach ausgetauscht werden können. Außerdem können für unterschiedliche Baureihen die entsprechend angepaßten Module nach Art eines Baukastensystems montiert werden.An advantage of this throttle valve module is to be seen in the fact that the individual modules, such as. B. the module 19, can be easily replaced. In addition, the correspondingly adapted modules can be installed in the manner of a modular system for different series.
