Description

TANKVERSCHLUSS FÜR KRAFTFAHRZEUGE FUEL CAP FOR MOTOR VEHICLES
Die Erfindung betrifft einen Tankverschluss für Kraftfahrzeuge, mit einem Verriege- lungsteil zur Verriegelung an einem komplementären Verriegelungsteil eines Tankstut zens, einem Verschlussteil zur Abdeckung einer Öffnung des Tankstutzens, und einem den Verriegelungsteil umgebenden, axial komprimierbaren Dichtungsring, der an einem Flansch des Verschlussteils abgestützt ist. Ein Beispiel eines Tankverschlusses dieser Art wird in DE 20 2014 009 044 Eli be schrieben. The invention relates to a tank cap for motor vehicles, with a locking part for locking on a complementary locking part of a tank neck, a closure part for covering an opening of the tank neck, and an axially compressible sealing ring surrounding the locking part, which is supported on a flange of the closure part . An example of a tank cap of this type is described in DE 20 2014 009 044 Eli.
Aufgabe der Erfindung ist es, einen Tankverschluss zu schaffen, der den Tankstutzen auch dann zuverlässig abdichtet, wenn im Tank des Fahrzeugs ein erhöhter Innendruck herrscht, wie er beispielsweise auftreten kann, wenn bei einem Hybridfahrzeug die von der Batterie erzeugte Wärme zu einer Erhitzung des Tanks führt. The object of the invention is to create a tank cap that reliably seals the filler neck even when there is increased internal pressure in the vehicle's tank, as can occur, for example, when the heat generated by the battery in a hybrid vehicle causes the tank to heat up leads.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Flansch auf seiner dem Dichtungsring zugewandten Oberfläche zumindest auf einem Teil seines Umfangs einen einstückig angeformten, gegenüber dieser Oberfläche erhabenen Wulst aufweist, dessen innerer Rand einen Radius hat, der größer ist als der Radius des Scheitels des Dich tungsringes. This object is achieved in that the flange on its surface facing the sealing ring at least on part of its circumference integrally formed, has against this surface raised bead, the inner edge has a radius which is greater than the radius of the apex of the device rings you.
Wenn im Tank ein normaler Innendruck herrscht, liegt der Dichtungsring mit seinem Scheitel radial innerhalb des Wulstes an der Oberfläche des Flansches des Ver schlussteils an, und die axiale Kompression des Dichtungsrings ist gerade so groß, dass ein gasdichter Verschluss des Tankstutzens sichergestellt wird, ohne dass die axiale Komprimierung zu einer Ermüdung und/oder dauerhaften Verformung des Dichtungs rings führt. Wenn der Innendruck steigt, hat der auf den inneren Umfang des Dichtungs ringes wirkende Gasdruck die Tendenz, den Dichtungsring aufzuweiten. Dabei trifft der Dichtungsring jedoch auf einen durch den Wulst gebildeten Hinterschnitt, der eine wei tere radiale Aufweitung des Dichtungsringes verhindert und stattdessen den Dichtungs ring um so fester gegen den Rand des Tankstutzens drückt. Auf diese Weise wird die Druckdichtheit des Tankverschlusses verbessert. When there is normal internal pressure in the tank, the apex of the sealing ring rests radially inside the bead on the surface of the flange of the closure part, and the axial compression of the sealing ring is just sufficient to ensure a gas-tight seal of the tank neck without the axial compression leads to fatigue and/or permanent deformation of the sealing ring. When the internal pressure increases, the gas pressure acting on the inner circumference of the seal ring tends to expand the seal ring. However, the sealing ring hits an undercut formed by the bead, which prevents further radial expansion of the sealing ring and instead presses the sealing ring all the more firmly against the edge of the tank neck. In this way, the pressure tightness of the tank cap is improved.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Advantageous refinements of the invention are specified in the dependent claims.
In einer vorteilhaften Ausführungsform ist der Wulst in Umfangsrichtung in mehrere durch Lücken voneinander getrennte Segmente aufgeteilt. Dadurch wird unter Normal bedingungen die Dauerbelastung des Dichtungsringes weiter reduziert, und bei erhöh tem Innendruck krallen sich die Segmente des Wulstes fest in die Oberfläche des Dich tungsringes ein. Auf diese Weise kann ein Durchbruch des unter Druck stehenden Gases besonders sicher verhindert werden. Im folgenden wird ein Ausführungsbeispiel anhand der Zeichnung näher erläutert. In an advantageous embodiment, the bead is divided in the circumferential direction into a plurality of segments separated from one another by gaps. This further reduces the permanent load on the sealing ring under normal conditions, and when the internal pressure increases, the segments of the bead dig into the surface of the sealing ring. In this way, a breakthrough of the pressurized gas can be prevented in a particularly reliable manner. In the following an embodiment is explained in more detail with reference to the drawing.
Es zeigen: Show it:
Fig. 1 einen axialen Teilschnitt eines Tankverschlusses gemäß der Erfin dung; und 1 shows an axial partial section of a tank cap according to the inventions; and
Fig. 2 einen Schnitt durch den Tankverschluss ohne Dichtungsring längs der Linie II-II in Fig. 1. Fig. 2 shows a section through the tank cap without a sealing ring along the line II-II in Fig. 1.
Der in Fig. 1 gezeigte Tankverschluss weist ein insgesamt topfförmiges, beispielsweise aus Kunststoff gespritztes Gehäuse 10 auf, das innenseitig einen zylindrischen Verriege lungsteil 12 und auf der Außenseite einen Verschlussteil 14 bildet. Der hier nicht voll ständig dargestellte Verriegelungsteil 12 ist dazu vorgesehen, in eine Öffnung eines Tankstutzens einzugreifen und ist beispielsweise mittels eines Bajonettverschlusses so in dem Tankstutzen verriegelbar, dass die Öffnung des Tankstutzens durch den Ver schlussteil 14 abgeschlossen wird. Der Verschlussteil 14 trägt auf der Außenseite einen Handgriff 16 und weist an seinem äußeren Umfang einen umlaufenden Flansch 18 auf. The tank cap shown in FIG. 1 has an overall pot-shaped housing 10, for example molded from plastic, which forms a cylindrical locking part 12 on the inside and a closure part 14 on the outside. The locking part 12 not fully shown here is intended to engage in an opening of a tank neck and can be locked in the tank neck, for example by means of a bayonet catch, that the opening of the tank neck is closed by the closing part 14 . The closure part 14 carries a handle 16 on the outside and has a peripheral flange 18 on its outer circumference.
Der Verriegelungsteil 12 ist auf der Innenseite des Flansches 18 von einem Dichtungs ring 20 aus gummi elastischem Material umgeben, der ein für solche Dichtungsringe üb liches Profil aufweist, mit einem annähernd kreisförmigen uerschnitt, jedoch mit einer am äußeren Umfang umlaufenden Furche, die den äußeren Umfangsbereich des Dich tungsringes in zwei Lippen unterteilt und die axiale Komprimierbarkeit des Dichtungs ringes erhöht. The locking part 12 is surrounded on the inside of the flange 18 by a sealing ring 20 made of rubber-elastic material, which has a profile customary for such sealing rings, with an approximately circular cross-section, but with a circumferential groove on the outer periphery, the outer peripheral region of the sealing ring is divided into two lips and the axial compressibility of the sealing ring is increased.
Der innere Umfangsrand des Dichtungsringes 20 ist in einer umlaufenden Rille 22 des Verriegelungsteils 12 aufgenommen und wird dadurch in axialer Richtung formschlüssig am Verriegelungsteil fixiert, während ein oberer Scheitel des Dichtungs ringes sich an einer unteren Oberfläche 24 des Flansches 18 abstützt. The inner peripheral edge of the sealing ring 20 is received in a circumferential groove 22 of the locking part 12 and is thereby in the axial direction positively fixed to the locking part, while an upper apex of the sealing ring is supported on a lower surface 24 of the flange 18.
Radial außerhalb des oberen Scheitels des Dichtungsringes 20 ist an der Unterseite des Flansches 18 ein umlaufender Wulst 26 gebildet, der gegenüber der Oberfläche 24 erha ben ist. In Fig. 2 ist zu erkennen, dass der Wulst 26 in Umfangsrichtung in acht Seg mente 28 unterteilt ist, die durch Lücken 30 voneinander getrennt sind. Die Lücken 30 erstrecken sich jeweeils über einen Umfangswinkel von vorzugsweise nicht mehr als 30°. Radially outside of the upper apex of the sealing ring 20, a circumferential bead 26 is formed on the underside of the flange 18, which is raised relative to the surface 24 ben. In FIG. 2 it can be seen that the bead 26 is divided into eight segments 28 in the circumferential direction, which are separated from one another by gaps 30 . The gaps 30 each extend over a circumferential angle of preferably not more than 30°.
Eine Berührungslinie 34, an der der obere Scheitel des Dichtungsringes 20 die Oberflä che 24 des Flansches 18 berührt, ist in Fig. 2 strichpunktiert eingezeichnet. Man er kennt, dass der innere Rand des Wulstes 26 radial außerhalb dieser Berührungslinie 34 liegt. A contact line 34 at which the upper apex of the sealing ring 20 touches the Oberflä surface 24 of the flange 18 is shown in phantom in FIG. It is known that the inner edge of the bead 26 lies radially outside of this line of contact 34 .
Die Höhe des Wulstes 26 gegenüber der Oberfläche 24 beträgt im gezeigten Beispiel etwa 1/12 bis 1/10 der Gesamthöhe des Dichtungsringes 20. In the example shown, the height of the bead 26 relative to the surface 24 is approximately 1/12 to 1/10 of the total height of the sealing ring 20.
Wenn in dem (nicht gezeigten) Tankstutzen ein erhöhter Gasdruck herrscht und Gas in der Rille 22 in die zwischen dieser Rille und dem Dichtungsring gebildete Fuge ein dringt und die Tendenz hat, den Dichtungsring radial aufzuweiten, so wird der Dich tungsring durch die Plateaus des Wulstes 26 formschlüssig in Position gehalten. If there is an increased gas pressure in the tank neck (not shown) and gas in the groove 22 penetrates into the joint formed between this groove and the sealing ring and has a tendency to expand the sealing ring radially, the sealing ring is compressed by the plateaus of the bead 26 held positively in position.
