Abstract
Geberzylinder (1) mit einem Schmutzschutz (3) für eine Öffnung an dem Geberzylinder (1) innerhalb einer hydraulischen Strecke zur Kupplungs- oder Bremsbetätigung eines Kraftfahrzeuges, wobei dieser Schmutzschutz (3) mindestens die durch den Öffnungsquerschnitt und die diesen umgebende Ringfläche des Geberzylinders (1) gebildete Abdeckfläche dichtend abdeckt, dadurch gekennzeichnet, dass dieser Schmutzschutz (3) durch eine Folie realisiert wird und die Größe der Fläche der Folie so gewählt ist, dass sie größer als die eigentlich erforderliche Abdeckfläche ist, so dass sie zumindest über der Hälfte eines durch den Außendurchmesser D gebildeten Umfanges der Abdeckungsfläche der Öffnung übersteht, wobei am restlichen Umfang der Öffnung die Fläche der Folie zusätzlich durch die Ausbildung einer Griffzunge (3a) vergrößert ist.Master cylinder (1) with a dirt guard (3) for an opening on the master cylinder (1) within a hydraulic path for actuating the clutch or brake of a motor vehicle, this dirt guard (3) covering at least the cross-section of the opening and the ring surface of the master cylinder surrounding it ( 1) sealingly covers the cover surface formed, characterized in that this dirt protection (3) is realized by a film and the size of the surface of the film is selected such that it is larger than the actually required cover surface, so that it covers at least half of a of the cover surface of the opening formed by the outer diameter D, the surface of the film being additionally enlarged by the formation of a gripping tongue (3a) on the remaining circumference of the opening.
Description
Die Erfindung betrifft einen Schmutzschutz für eine Öffnung an einem Bauteil in einer hydraulischen Strecke zur Kupplungs- oder Bremsbetätigung eines Kraftfahrzeuges mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a dirt guard for an opening in a component in a hydraulic line for actuating the clutch or brake of a motor vehicle, having the features of the preamble of claim 1.
Während des Transports bzw. vor der Montage aller erforderlichen Bauteile, wie Leitungen, Geber- und Nehmerzylinder, Behälter, Ventile usw. für eine hydraulische Strecke ist es notwendig, deren Anschlussöffnungen vor Verschmutzung zu schützen. Dazu werden diese Anschlussöffnungen mit Verschlüssen in Form von Kappen oder Stopfen versehen, um kurz vor der Montage entfernt zu werden, da sie nicht weiter benötigt werden. Diese Verschlüsse bestehen vorzugsweise aus Kunststoff und werden üblicherweise, wenn sie als Kappen ausgebildet sind, auf die jeweilige Öffnung aufgedrückt oder als Stopfen ausgebildet, in die Öffnung hineingedrückt. Das Entfernen dieser Verschlüsse stellt einen erheblichen Arbeits- bzw. Zeitaufwand dar, wobei die Verschlüsse selbst bereits einen erheblichen Kostenfaktor darstellen. Um die Verschlüsse erneut verwenden zu können, müssen diese gereinigt werden. Ansonsten werden sie als Wegwerfartikel einem Recyclingprozess zugeführt und benötigen bis dahin einen erheblichen Platzbedarf.During transport or before the installation of all necessary components, such as lines, master and slave cylinders, tanks, valves, etc. for a hydraulic system, it is necessary to protect the connection openings from dirt. For this purpose, these connection openings are provided with closures in the form of caps or plugs in order to be removed shortly before assembly, since they are no longer required. These closures are preferably made of plastic and, if they are in the form of caps, are usually pressed onto the respective opening or, in the form of plugs, are pressed into the opening. The removal of these closures represents a considerable expenditure of work and time, with the closures themselves already representing a considerable cost factor. In order to be able to use the closures again, they must be cleaned. Otherwise they are fed into a recycling process as disposable items and require a considerable amount of space until then.
Aus der Lebensmittelindustrie ist es bekannt, aus Kunststoff hergestellte Verpackungsbehälter oder Verpackungsgefäße mit heißversiegelten Kunststoffdeckeln zu verschließen, wie dies in der US-PS
Weitere Verpackungsbehälter mit einer Folienabdeckung sind beispielsweise in der
Der Erfindung liegt daher die Aufgabe zugrunde, einen Schmutzschutz für eine Öffnung an einem Bauteil in einer hydraulischen Strecke, insbesondere bis zu deren Montage zu gewährleisten, mit dem ein Eindringen von Schmutz sicher verhindert wird, zur Montage leicht und ohne Zuhilfenahme eines Werkzeuges entfernbar ist, um den vollen Öffnungsquerschnitt freizugeben und gleichzeitig kostengünstig herstellbar ist.The invention is therefore based on the object of ensuring dirt protection for an opening on a component in a hydraulic line, in particular up to its assembly, with which the ingress of dirt is reliably prevented, can be removed easily for assembly and without the aid of a tool, to release the full opening cross-section and at the same time can be produced inexpensively.
Diese Aufgabe wird mit einem Schmutzschutz mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.This object is achieved with a dirt guard with the features of claim 1. Advantageous configurations emerge from the dependent claims.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels und zugehöriger Zeichnungen näher erläutert.The invention is explained in more detail below using an exemplary embodiment and associated drawings.

1 a dirt protection according to the invention, which covers the line connection of a master cylinder, -
2 a perspective view of the enlarged dirt protection according to FIG1 .
Für die Montage der Bauteile in der hydraulischen Strecke werden deren mit der Folie 3 verschlossene Anschlussöffnungen durch Ziehen an der Griffzunge 3a von der Öffnung entfernt und diese damit ohne Zuhilfenahme eines Werkzeuges freigelegt. Somit wird auf einfache Art und Weise eine Abdeckung einer Bauteilöffnung geschaffen, die diese vor Schmutzeinwirkung wirksam schützt, kostengünstig herstellbar ist und leicht für einen nachfolgenden Arbeitsprozess entfernbar ist.For the assembly of the components in the hydraulic line, their connection openings, which are closed with the
