Schutzvorrichtung für Elemente in Kraftfahrzeugen Stand der Technik Protection device for elements in motor vehicles State of the art
Die Erfindung geht aus von einer Schutzvorrichtung für Elemente in Kraftfahrzeugen nach der Gattung des Anspruchs 1.The invention is based on a protective device for elements in motor vehicles according to the preamble of claim 1.
Es ist bekannt, Elemente in Kraftfahrzeugen, insbesondere Leitungen wie beispielsweise Zündleitungen, die frei zugänglich und durch Wildtierverbiß, speziell durch Marderverbiß, gefährdet sind, durch eine Umhüllung zu schützen. Da die Leitungen aufgrund der beengten Platzverhältnisse im Kraftfahrzeug in der Regel gekrümmt verlaufen, wird die Umhüllung durch eine Aneinanderreihung von sogenannten Einzelperlen dargestellt. Diese Einzelperlen sind kurze Rohrabschnitte, deren Wandung derart stufig ausgebildet ist, daß sie sich bereichsweise überlappend montieren lassen und gekrümmt verlegbar sind.It is known to protect elements in motor vehicles, in particular cables such as ignition cables, which are freely accessible and at risk from damage by wild animals, especially martens, by means of a covering. Since the cables are usually curved due to the limited space in the motor vehicle, the covering is made up of a series of so-called individual beads. These individual beads are short pipe sections whose walls are designed in such a stepped manner that they can be installed overlapping in some areas and laid in a curved manner.
Diese Umhüllung ist jedoch kostenintensiv, da sie aus einzeln herzustellenden Perlen besteht, die abgezählt auf die zu schützende Leitung aufzubringen sind, so daß die Umhüllung neben hohen Herstellkosten auch mit hohen Montagekosten durch die Art der Montierbarkeit belastet ist.However, this coating is cost-intensive because it consists of individually manufactured beads that have to be applied in a numbered manner to the cable to be protected, so that the coating is not only expensive to produce but also has high installation costs due to the way it is installed.

Die erfindungsgemäße Schutzvorrichtung mit den kennzeichnenden Merkmalen des Anspruch 1 hat demgegenüber den Vorteil, daß die zuvor erwähnte Unzulänglichkeit vermieden wird und eine preisgünstige Schutzvorrichtung für Elemente, insbesondere freiliegende Leitungen im Kraftfahrzeug geschaffen ist. Dazu ist die Schutzvorrichtung als ein vorzugsweise einstückiger, durch die Art der Ausbildung wildtierverbißresistenter Wellrohrschlauch ausgebildet, der in der Herstellung preisgünstig ist. Durch die vorzugsweise einstückige Ausbildung ist der krümmungsfähige Wellrohrschlauch schnell montierbar, so daß nur geringe Montagekosten entstehen.The protective device according to the invention with the characterizing features of claim 1 has the advantage that the previously mentioned inadequacy is avoided and an inexpensive protective device for elements, in particular exposed cables in the motor vehicle, is created. For this purpose, the protective device is designed as a preferably one-piece corrugated hose that is resistant to bites from wild animals due to the type of design and is inexpensive to manufacture.

Beschreibung des AusführungsbeispielsDescription of the embodiment
Eine Schutzvorrichtung für Elemente, insbesondere für freiliegende Leitungen in Kraftfahrzeugen ist in den Figuren 1 und 2 dargestellt. Es handelt sich dabei um einen einstückigen Wellrohrschlauch 11. Dessen Wandung 12 ist über seinen Längsverlauf, im Querschnitt gesehen, periodisch in Wellen 13 unterteilt. Eine Welle 13 setzt sich abschnittsweise zusammen aus einem Wellenberg 14, einemA protective device for elements, in particular for exposed cables in motor vehicles, is shown in Figures 1 and 2. It is a one-piece corrugated hose 11. Its wall 12 is periodically divided into waves 13 along its length, seen in cross section. A wave 13 is made up of sections of a wave crest 14, a
R. 27943R. 27943
Wellengrund 16, einer ersten Wellenflanke 17 und einer zweiten Wellenflanke 18. Der Bereich des Wellenberges 14 bildet die äußere und der Bereich des Wellengrundes 16 die innere Begrenzung des Wellrohrschlauches 11. Die erste Wellenflanke 17 verläuft vom Wellengrund 16 zum Wellenberg 14 und die zweite Wellenflanke 18 vom Wellenberg 14 zum Wellengrund 16 der nächsten Welle 13. Die Wellenflanken 17, 18 verlaufen, steil aufsteigend, nahezu senkrecht zur Längserstreckung des Wellrohrschlauches 11.Wave base 16, a first wave flank 17 and a second wave flank 18. The area of the wave crest 14 forms the outer and the area of the wave base 16 the inner boundary of the corrugated pipe hose 11. The first wave flank 17 runs from the wave base 16 to the wave crest 14 and the second wave flank 18 from the wave crest 14 to the wave base 16 of the next wave 13. The wave flanks 17, 18 run, rising steeply, almost perpendicular to the longitudinal extension of the corrugated pipe hose 11.
Jede der Wellen 13 ist im Bereich des Wellenberges 14 abgeflacht. Die Dicke der Wandung 12 ist hier stärker ausgeführt als in den übrigen Abschnitten der Welle 13, insbesondere als im Wellengrund 16. Der Wellrohrschlauch 11 ist so kompakt ausgebildet, daß ein lichter Abstand 19 in Längsrichtung des Wellrohrschlauches 11 zwischen benachbarten Wellen 13 drei mm nicht übersteigt. Die Tiefe einer Welle 13, entsprechend dem lotrechten Abstand zwischen Wellenberg 14 und Wellengrund 16, ist größer als der AbstandEach of the waves 13 is flattened in the area of the wave crest 14. The thickness of the wall 12 is thicker here than in the other sections of the wave 13, in particular than in the wave base 16. The corrugated tube 11 is so compact that a clear distance 19 in the longitudinal direction of the corrugated tube 11 between adjacent waves 13 does not exceed three mm. The depth of a wave 13, corresponding to the vertical distance between the wave crest 14 and the wave base 16, is greater than the distance
19. Die Länge der Wellenflanken 17, 18 entspricht in etwa der Länge des abgeflachten Wellenberges 14.19. The length of the wave flanks 17, 18 corresponds approximately to the length of the flattened wave crest 14.
Durch diesen Aufbau ist der Wellrohrschlauch 11 einerseits in außenliegenden Bereichen massiv und andererseits in innenliegenden Bereichen noch verformungsfähig ausgebildet. Das Dickenverhältnis der Wandung 12 zwischen dem Wellenberg 14 und dem Wellengrund 16 beträgt etwa 3:1. Der lichte Abstand 19 von einander gegenüberliegenden Wellenflanken 17, 18 in Längsrichtung des Wellrohrschlauches 11 ist jeweils so gewählt, daß dieser einerseits geringer ist als die Querschnittsabmaße der Kauzähne eines Wildtiers, insbesondere eines Marders und andererseits dieser eine Krümmung des Wellrohrschlauches 11 zuläßt.Due to this structure, the corrugated tube hose 11 is solid in the outer areas on the one hand and still deformable in the inner areas on the other. The thickness ratio of the wall 12 between the wave crest 14 and the wave base 16 is approximately 3:1. The clear distance 19 between opposing wave flanks 17, 18 in the longitudinal direction of the corrugated tube hose 11 is selected in such a way that, on the one hand, it is smaller than the cross-sectional dimensions of the chewing teeth of a wild animal, in particular a marten, and, on the other hand, this allows the corrugated tube hose 11 to bend.
R. 27943R. 27943
Der Wellrohrschlauch 11 besteht aus einem zähelastischen Material, vorzugsweise aus mit Glasfasern oder Mineralstoffen gefülltem Polyamid.The corrugated pipe hose 11 consists of a tough elastic material, preferably polyamide filled with glass fibers or minerals.
Durch einen solchermaßen ausgebildeten Wellrohrschlauch 11 ist ein Wildtier, insbesondere Marder, gehindert, eine in dem Wellrohrschiauch 11 verlaufende Leitung die Strom, Spannung, Flüssigkeit oder Gas führen kann, oder ein anderes schützenswertes Element, beispielsweise ein Sensor, durch Verbiß zu beschädigen. Die Kauwerkzeuge des Marders finden in den massiv ausgebildeten, mit einer Dicke von etwa 3 mm versehenen, äußeren Abschnitten des Wellrohrschlauches 11 hinreichend Widerstand. Versuche haben gezeigt, daß ein Marder nur in der Lage ist, diese Abschnitte geringfügig zu verformen.A corrugated pipe hose 11 designed in this way prevents a wild animal, in particular a marten, from damaging a cable running through the corrugated pipe hose 11 that can carry electricity, voltage, liquid or gas, or another element that needs to be protected, such as a sensor, by biting into it. The marten's chewing tools find sufficient resistance in the solid outer sections of the corrugated pipe hose 11, which are approximately 3 mm thick. Tests have shown that a marten is only able to deform these sections slightly.
Des weiteren sind die Querschnittsabmaße der Kauwerkzeuge des Wildtiers, insbesondere eines Marders so groß, daß sie den lichten Abstand 19 übersteigen und nicht in denFurthermore, the cross-sectional dimensions of the chewing tools of the wild animal, especially of a marten, are so large that they exceed the clearance 19 and do not fit into the
.20 gegenüber dem Wellenberg 14 mit geringerer Dicke der Wandung 12 versehenen Abschnitt des Wellengrundes 16 vordringen können, ebenso wie in die Wellenflanken 17, 18, die gegenüber dem Wellenberg 14 ebenfalls eine geringere Dicke der Wandung 12 aufweisen und zudem auch noch weitgehend in der Bißrichtung des Marders liegen und damit diesem nur eine geringe Angriffsfläche bieten würden..20 can penetrate into the section of the wave base 16 which has a thinner wall 12 than the wave crest 14, as well as into the wave flanks 17, 18 which also have a thinner wall 12 than the wave crest 14 and which also lie largely in the direction in which the marten would bite and would therefore only offer the marten a small area to attack.
Ein solchermaßen gegen Wildtierverbiß resistenter Wellrohrschlauch 11 zum Schutz von Elemente, insbesondere freiliegender Leitungen in Kraftfahrzeugen, kann in einen kombinierten Kunststoffspritz- und Kunststoffblasverfahren preisgünstig hergestellt werden und ermöglicht durch seine einstückige und zugleich krümmungsfähige Form eine schnelle und kostengünstige Montage.A corrugated pipe hose 11 that is resistant to wild animal bites in this way for protecting elements, in particular exposed lines in motor vehicles, can be inexpensively manufactured using a combined plastic injection molding and plastic blow molding process and, thanks to its one-piece and simultaneously bendable shape, enables quick and inexpensive assembly.
R. 27943R. 27943
Der Wellrohrschlauch 11 kann dabei aus einer wendelförmig um die Längsachse des Wellrohrschlauches 11 verlaufenden, die Wellen 13 bildenden Rippe oder um sich aneinanderreihende und somit die Wellen 13 bildende, zueinander parallele Rippen bestehen.The corrugated tube hose 11 can consist of a rib running spirally around the longitudinal axis of the corrugated tube hose 11 and forming the waves 13 or of ribs arranged in a row and parallel to one another, thus forming the waves 13.
