Description
Die
Erfindung bezieht sich auf eine Drosselklappe. Drosselklappen sind
bekannt. Sie werden in der Regel in sogenannten Drosselklappenstutzen
angeordnet. In der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Drosselklappe zu schaffen, mit der es möglich ist, die nachteilige Ausbildung von Eis zwischen der Drosselklappe und den Drosselklappenstutzen bei diesen Bedingungen weitgehend zu vermeiden.Of the Invention is therefore based on the object, a throttle valve create with it possible is the adverse formation of ice between the throttle and the throttle body at these conditions largely to avoid.
Die der Erfindung zugrunde liegende Aufgabe wird durch eine Drosselklappe gelöst, bei der mindestens die Oberfläche einer Seite mindestens teilweise mit einer Gitterstruktur versehen ist. Die Drosselklappe kann dabei aus Kunststoff oder Metall gefertigt sein. In der Regel reicht es schon aus, eine Seite mindestens teilweise mit einer Gitterstruktur zu versehen. Aus fertigungstechnischen Gründen kann es jedoch vorteilhaft sein, beide Seiten der Drosselklappe teilweise mit einer Gitterstruktur zu versehen, wobei "teilweise" meint, dass Teilflächen dieser Seite mit der Gitterstruktur versehen sind. Die Gitterstruktur selbst kann dabei konstruktiv auf verschiedenartigste Weise gestaltet sein. So kann es beispielsweise möglich sein, die Gitterstruktur durch ein Aufbringen von Noppen herzustellen, die nebeneinander angeordnet sind und so die Gitterstruktur bilden.The The object underlying the invention is achieved by a throttle valve solved, at least the surface one side at least partially provided with a grid structure is. The throttle valve can be made of plastic or metal be. In general, it is enough, one side at least partially to be provided with a grid structure. From production engineering establish However, it may be beneficial to both sides of the throttle partially provided with a lattice structure, where "partially" means that partial surfaces of this Side are provided with the grid structure. The grid structure itself can be structurally designed in a variety of ways. For example, it may be possible be to produce the grid structure by applying nubs, which are arranged side by side and thus form the lattice structure.
Es hat sich in überraschender Weise gezeigt, dass auskondensierte Tröpfchen auf der Oberfläche der Drosselklappe verbleiben und somit weitgehend vermieden wird, dass sie die Kante der Drosselklappe erreichen. Eine Eisbildung zwischen der Drosselklappe und dem Drosselklappenstutzen wird somit in vorteilhafter Weise vermieden.It has become more surprising Were shown that condensed droplets on the surface of the Throttle remain and thus largely avoided that they reach the edge of the throttle. An ice formation between the throttle and the throttle body is thus in an advantageous Way avoided.
Eine bevorzugte Ausgestaltung der Erfindung besteht darin, dass die Oberfläche der zum Motor gerichteten Seite mindestens teilweise mit einer Gitterstruktur versehen ist. In diesem Bereich des Drosselklappenstutzens liegt in der Regel ein Luft-Treibstoffgemisch vor, so dass neben Wasser auch Treibstofftröpfchen bei niedrigen Temperaturen auskondensieren können. Um eine Vereisung der auskondensierten Tröpfchen an der Kante der Drosselklappe nahezu vollständig zu vermeiden, sollte diejenige Seite der Drosselklappe mindestens teilweise mit einer Gitterstruktur versehen sein, die dem Motor zugewandt ist.A Preferred embodiment of the invention is that the surface of the towards the engine side at least partially with a grid structure is provided. In this area of the throttle body is located usually an air-fuel mixture in front, so in addition to water too fuel droplets can condense at low temperatures. To an icing of the condensed droplet To almost completely avoid the edge of the throttle should be the one Side of the throttle at least partially with a grid structure be provided, which faces the engine.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist als Gitterstruktur ein Raster aus Nuten angeordnet. Dieses Raster aus Nuten kann beispielsweise eingefräst, eingestanzt oder, sofern die Drosselklappe aus Kunststoff gefertigt ist, durch eine konstruktive Anordnung des Spritzwerkzeuges beim Spritzgießvorgang eingearbeitet werden. Die Nuten können beispielsweise kurvenförmig angeordnet sein.According to one Another preferred embodiment of the invention is as a lattice structure a grid of grooves arranged. This grid of grooves, for example milled, stamped or, if the throttle made of plastic is, by a constructive arrangement of the injection mold when injection molding be incorporated. The grooves can be arranged, for example, curved be.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass das Raster aus parallelen Nuten und zu diesen senkrecht verlaufenden Nuten besteht. Die Tiefe der Nuten liegt dabei im Bereich von 0,3 bis 0,5 mm. Dies erleichtert die Herstellung der Drosselklappe, was eine Serienfertigung erleichtert.To A further embodiment of the invention provides that the grid of parallel grooves and perpendicular to these Grooves exists. The depth of the grooves is in the range of 0.3 up to 0.5 mm. This facilitates the manufacture of the throttle valve, which facilitates mass production.
Gemäß einer weiteren Ausgestaltung der Erfindung schließen die parallelen Nuten und die zu diesen senkrecht verlaufenden Nuten quadratische Vorsprünge ein. Dabei haben die Vorsprünge in der Draufsicht eine quadratische Form. Auf diese Weise ist sichergestellt, dass der gesamte Bereich der Gitterstruktur die auskondensierten Tröpfchen in gleichartiger Weise festhält und ein Erreichen der Kante der Drosselklappe in gleicher Weise verhindert.According to one Another embodiment of the invention close the parallel grooves and the square to these perpendicular grooves a square projections. The projections have in plan view a square shape. In this way it is ensured that the entire area of the lattice structure condensed out droplet holds in a similar way and reaching the edge of the throttle in the same way prevented.
Nach einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass als Gitterstruktur ein Raster aus Vorsprüngen angeordnet ist, die somit Hohlräume umschließen. Die Höhe der Vorsprünge liegt dabei im Bereich von 0,3 bis 0,5 mm. Die Vorsprünge können beispielsweise kurvenförmig ausgebildet sein. Dabei ist vorteilhaft, dass die auskondensierten Tröpfchen in den Hohlräumen gehalten werden und somit nicht an den Rand der Drosselklappe gelangen können.According to a further preferred embodiment of the invention it is provided that a grid of projections is arranged as a lattice structure, which thus enclose cavities. The height of the projections is in the range of 0.3 to 0.5 mm. The projections may be curved, for example be educated. It is advantageous that the condensed droplets are held in the cavities and thus can not get to the edge of the throttle.
Nach einer weiteren Ausgestaltung der Erfindung besteht das Raster aus parallelen Vorsprüngen und zu diesen senkrecht verlaufenden Vorsprüngen. Dies wirkt sich vorteilhaft auf die Herstellung der Drosselklappe aus, was eine Serienfertigung begünstigt.To In another embodiment of the invention, the grid is made parallel projections and to these perpendicular protrusions. This has an advantageous effect on the manufacture of the throttle, resulting in mass production favored.
Gemäß einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die parallelen Vorsprünge und die zu diesen senkrecht verlaufenden Vorsprüngen quadratische Hohlräume umschließen. Dies vereinfacht die Herstellung der Drosselklappe, besonders dann, wenn sie aus Kunststoff gefertigt ist, da das für das Spritzgießen erforderliche Werkzeug konstruktiv relativ einfach gestaltet sein kann.According to one Another embodiment of the invention, it is provided that the parallel projections and enclose square cavities to these perpendicular projections. This simplifies the manufacture of the throttle, especially if It is made of plastic, as required for injection molding Tool constructively can be designed relatively simple.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist die Gitterstruktur auf mindestens einer Seite durch auf dieser Seite angeordnete Stege unterteilt. Die Stege dienen dabei der Erhöhung der Stabilität der Drosselklappe. Die Anordnung einer Gitterstruktur zwischen den jeweiligen Stegen erleichtert ein Zurückhalten der auskondensierten Tröpfchen über die gesamte Oberfläche der Drosselklappe.According to one Another preferred embodiment of the invention is the lattice structure on at least one side by webs arranged on this side divided. The webs serve to increase the stability of the throttle valve. The arrangement of a grid structure between the respective webs facilitates a retention the condensed droplets over the entire surface the throttle.
