Abstract
Description
Die Erfindung betrifft eine Welle, die um einen begrenzten Drehwinkel um ihre Längsachse gegenüber einer Öffnung in einer Trennwand dreht, durch die sie ragt, wobei zwischen der Welle und der Öffnung eine Dichtung angeordnet ist.The invention relates to a shaft that rotates by a limited angle of rotation about its longitudinal axis with respect to an opening in a partition through which it projects, wherein a seal is arranged between the shaft and the opening.

Weniger aufwendig sind im Kraftfahrzeugbau die Ausgestaltungen von Dichtungen, Welle und Führungen bei einer nur begrenzt drehbaren Welle eines aktiven Spoilers. Hierzu wird beispielsweise eine Gummimanschette verwendet, die mit ihrem einen Ende unter Vorspannung auf den Wellendurchtritt in der Trennwand aufgeschoben ist. Diese Wellendurchtritte an der Spoilerkassette sind jedoch regelmäßig schräg zur Längsachse der Welle ausgerichtet, so dass es bei der Anlage der Dichtung an der Welle zu einseitigen Belastungen des Dichtsystems mit gleichzeitig einseitiger Spaltöffnung auf der gegenüberliegenden Seite kommt. Zusätzlich entsteht insbesondere durch Verschleiß und klimatische Einflüsse eine Spaltbildung. Damit kommt es zu Undichtigkeiten zwischen den beiden durch die Trennwand voneinander getrennten Räumen.Less elaborate in automotive engineering are the embodiments of seals, shaft and guides in a limited rotatable shaft of an active spoiler. For this example, a rubber boot is used, which is pushed with its one end under bias on the shaft passage in the partition. However, these shaft passages on the spoiler cassette are regularly aligned obliquely to the longitudinal axis of the shaft, so that it comes to one-sided loads of the sealing system with simultaneous unilateral gap opening on the opposite side when the seal on the shaft. In addition, in particular due to wear and climatic influences, a gap formation. This leads to leaks between the two separated by the partition walls spaces.
Aufgabe der Erfindung ist es deshalb, eine Anordnung aus Welle mit dazugehöriger Dichtung zur Verfügung zu stellen, die es ermöglicht, bei einer begrenzten Drehung um die Längsachse der Welle mit möglichst einfachen Mitteln eine Dichtigkeit zwischen den beiden Räumen, die durch eine Trennwand, durch deren Öffnung die Welle ragt, voneinander getrennt sind, zu realisieren.The object of the invention is therefore to provide an arrangement of shaft with associated seal available, which makes it possible with a limited rotation about the longitudinal axis of the shaft with the simplest possible means a tightness between the two spaces by a partition through which Opening the shaft protrudes, are separated from each other, to realize.
Diese Aufgabe wird durch eine Welle samt Dichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a shaft including seal with the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.
