Abstract

A brake line is disclosed, as well as its union with the brake housing (1). In order to master higher braking powers at possibly the same weight and with the same brake dimensions, an increased temperature of the brake fluid must be accommodated. The object of the invention is to insulate as much as possible the brake hose (11) which extends from the master cylinder to the brake housing (1) from high temperatures of the brake fluid. For that purpose, the brake line is provided at the end next to the brake with an intermediate pipe (4) which keeps the brake hose (11) away from the brake housing (1) and which at the same times helps cool the brake fluid. Advantageous developments of the invention concern the union (9) between the pipe section (4) and the brake hose (11), as well as a simple means (10) on the housing (1) for locking the pipe in rotation.

Description

Wärmegeschützter Anschluß einer Bremsleitung an ein BremsengehäuseThermally protected connection of a brake line to a brake housing
Die Erfindung betrifft einen Anschluß einer Brems¬ leitung an ein Bremsengehäuse. Über derartige Brems- leitungen wird im Betätigungsfall der Bremse vielfach ein Druck von über lOObar übertragen. Gleichzeitig können bei Unregelmäßigkeiten in der Bremsleitung die Bremsen vollkommen ausfallen. Bremsleitungen müssen daher sehr sorgfältig konstruiert und montiert werden, damit ein Totalausfall der Bremse ausgeschlossen ist.The invention relates to a connection of a brake line to a brake housing. When the brake is actuated, a pressure of over 100 bar is often transmitted via such brake lines. At the same time, the brakes can fail completely in the event of irregularities in the brake line. Brake lines must therefore be designed and assembled very carefully so that a total failure of the brake is impossible.
Wie aus dem Bremsenhandbuch, (9. Auflage des Bartsch-Verlag, S. 269, insbesondere Fig.4) ersichtlich, ist die Bremsleitungen vorzugsweise über einen Anschlußstutzen insbesondere einen Ringstutzen mit Hohlschraube an das Gehäuse einer Bremse ange¬ schlossen. Dabei wurde die Schlauchleitung bis zur der Armatur geführt, über die sie dann mit dem Bremsenge¬ häuse unmittelbar verbunden wurde. Aufgrund der immer größeren abzubremsenden Leistungen der Fahrzeuge und der wegen Platz- und Gewichtersparnis immer kleineren Dimensionierung der Bremsen, muß bei heftigem Abbremsen mit sehr hohen Temperaturen der Bremsflüssigkeit gerechnet werden. Andererseits soll vermieden werden, daß die in den Schläuchen befindliche Bremsflüssigkeit und somit auch das Schlauchmaterial selbst Temperaturen von + 100°C übersteigt.As can be seen from the brake manual (9th edition of Bartsch-Verlag, p. 269, in particular Fig. 4), the brake lines are preferably connected to the housing of a brake via a connecting piece, in particular an annular piece with a hollow screw. The hose line was led to the valve, via which it was then connected directly to the brake housing. Due to the ever increasing performance of the vehicles to be braked and the smaller dimensions of the brakes due to space and weight savings, the brakes have to be applied violently very high temperatures of the brake fluid can be expected. On the other hand, it should be avoided that the brake fluid in the hoses and thus the hose material itself exceeds temperatures of + 100 ° C.
Die Erfindung geht daher aus von einem Anschluß einer Bremsleitung an ein Bremsengehäuse der sich aus dem Oberbegriff des Anspruches 1 ergebenden Gattung.The invention is therefore based on a connection of a brake line to a brake housing of the type resulting from the preamble of claim 1.
Aufgabe der Erfindung ist es, einen Anschluß derart auszugestalten, daß die Temperatur des aus einer Kombination von Gummi und Textilmaterial bestehenden Bremsschlauches möglichst gering gehalten wird.The object of the invention is to design a connection such that the temperature of the brake hose consisting of a combination of rubber and textile material is kept as low as possible.
Die Aufgabe wird durch die sich aus dem kennzeichnenden Teil des Anspruchs 1 ergebende Merkmalskombination gelöst. Die Erfindung besteht im Prinzip also darin, den Bremsschlauch über eine Armatur nicht unmittelbar an das Bremsgehäuse anzuschließen, sondern ein Zwischenrohr einzufügen, welches einerseits mit dem Bremsengehäuse und andererseits über einen Verbinder mit dem Bremsschlauch verbunden ist. Hierdurch ist der Bremsschlauch eine hinreichend große Wegstrecke und damit auch Volumenstrecke von dem Bremsengehäuse entfernt, so daß die den Bremskolben umgebende erhitzte Bremsflüssigkeit bei Beendigung des Bremsvorgangs nicht unmittelbar in den Schlauch gedrückt wird. Weiterhin hat das Zwischenrohr eine Kühlfähigkeit, so daß die in dem Zwischenrohr stehende Bremsflüssigkeit schon vorgekühlt nach dem Bremsvorgang in den Schlauch gedrückt wird. Um die Bremsflüssigkeit möglichst direkt von dem erhitzten Bremsengehäuse wegzuleiten, empfiehlt sich die Anwendung der Merkmalskombination nach Anspruch 2, da hier die Armatur und damit auch das Zwischenrohr senkrecht aus dem Bremsengehäuse austritt. Die Verwendung eines Zwischenrohrs schafft auch andere Möglichkeiten der Vormontage, indem beispielsweise das an dem Bremsengehäuse befestigte Zwischenrohr vormontiert von den Zulieferanten an den Autohersteller geliefert werden kann. Hierdurch ergeben sich auch Vereinfachungsmöglichkeiten bei der Befestigung des Rohres an dem Bremsengehäuse, beispielsweise durch Einpressen, Eingießen oder ähnliche Maßnahmen.The object is achieved by the combination of features resulting from the characterizing part of claim 1. In principle, the invention therefore consists in not connecting the brake hose directly to the brake housing via a fitting, but instead inserting an intermediate tube which is connected to the brake housing on the one hand and to the brake hose via a connector on the other hand. As a result, the brake hose is a sufficiently long distance and thus also a volume distance from the brake housing, so that the heated brake fluid surrounding the brake piston is not pressed directly into the hose when the braking process is completed. Furthermore, the intermediate tube has a cooling capacity, so that the brake fluid standing in the intermediate tube is pressed into the hose already pre-cooled after the braking process. In order to conduct the brake fluid away from the heated brake housing as directly as possible, the use of the combination of features according to claim 2 is recommended, since here the valve and thus also the intermediate pipe emerge vertically from the brake housing. The use of an intermediate tube also creates other possibilities for preassembly, in that, for example, the intermediate tube attached to the brake housing can be delivered preassembled by the suppliers to the car manufacturer. This also results in simplification options when fastening the tube to the brake housing, for example by pressing, pouring or similar measures.
Um bei möglichst geringem Raumbedarf das Zwischenrohr lang halten zu können, empfiehlt sich in Weiterbildung der Erfindung die Anwendung der Merkmalskombination nach Anspruch 3. Das Rohr wird hier in einem zweiten Abschnitt bogenförmig vorzugsweise halbkreisförmig, aber auch spiralförmig oder ringförmig verlegt, wobei darauf zu achten ist, daß durch die Krümmung die Durchtrittsfläche des Rohres nicht verengt wird.In order to be able to keep the intermediate tube long with as little space as possible, in a further development of the invention the use of the combination of features according to claim 3 is recommended. The tube is laid here in a second section in an arcuate manner, preferably semicircularly, but also spirally or annularly, whereby care must be taken that the passage surface of the tube is not narrowed by the curvature.
Die oben beschriebene Konstruktion gibt noch die Möglichkeit in einfacher Weise für eine Drehsicherung des Rohres gegenüber dem Gehäuse zu sorgen. Hierbei empfiehlt sich insbesondere die Anwendung der Merkmale nach Anspruch 4. Dabei wird das Rohr nach dem kühlenden Abschnitt in die Nähe des Bremsengehäuses zurückgeführt und dort durch einen beispielsweise gabelförmigen Ansatz gehalten, der dem Rohr eine hinreichende mechanische Abstützung verschafft, in deren Umgebung dann der Verbinder zu dem Bremsschlauch angeordnet werden kann.The construction described above still gives the possibility of ensuring that the pipe is secured against rotation relative to the housing. In this case, the use of the features according to claim 4 is particularly recommended. The tube is returned to the vicinity of the brake housing after the cooling section and held there by, for example, a fork-shaped attachment, which provides the tube with sufficient mechanical support, in the vicinity of which the connector to the brake hose can then be arranged.
Dieses mittels mehrerer Blöcke, einem gabelförmigen Ansatz oder in anderer Form das Rohr haltende Hilfsmittel kann einstückig mit dem Gehäuse ausgeformt sein, indem es beispielsweise angegossen oder angeschweißt ist.This auxiliary means holding the tube by means of several blocks, a fork-shaped extension or in another form can be formed in one piece with the housing, for example by being cast on or welded on.
Soweit man dafür sorgt, daß das Zwischenrohr aus dem Bremsengehäuse herauslösbar ist, empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 6, indem das Zwischenrohr mit dem Bremsschlauch über einen Verbinder unlösbar verbunden ist. Hierdurch kann sich die Verbindung zwischen Schlauch und Rohr erheblich vereinfachen und insgesamt die Bremsleitung preiswerter hergestellt werden.Insofar as it is ensured that the intermediate tube can be detached from the brake housing, the combination of features according to claim 6 is recommended in a further development of the invention, in that the intermediate tube is non-detachably connected to the brake hose via a connector. This can considerably simplify the connection between the hose and the tube and, overall, the brake line can be produced more cheaply.
Eine besonders vorteilhafte Maßnahme hierzu ergibt sich, durch die Anwendung der Merkmalskombination nach Anspruch 7. Durch Anwendung der Befestigung nach Anspruch 8 läßt sich die Herstellung der Bremsleitung noch mehr vereinfachen. Eine zusätzliche Halterung des Rohrs in dem Verbinder erhält man durch die Maßnahmen nach Anspruch 9.A particularly advantageous measure for this results from the use of the combination of features according to claim 7. By using the fastening according to claim 8, the manufacture of the brake line can be simplified even more. An additional mounting of the tube in the connector is obtained by the measures according to claim 9.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Die Zeichnung zeigt ausschnittsweise ein Bremssattelgehäuse 1 mit einer Gewindebohrung 2, in die als Armatur für ein Zwischenrohr 4 eine Überwurfschraube 3 dient. Durch die Überwurfschraube 3 kann das dem Bremsengehäuse 1 zugewandte Ende des Zwischenrohrs 4 mittels des Dichtbördeis 5 druckdicht verschraubt werden. Es tritt somit ein erster Abschnitt 6 des Zwischenrohres 4 senkrecht aus dem Bremsengehäuse 1 aus. Dieser erster Abschnitt 6 geht in einen zweiten Abschnitt 7 über, der halbkreisförmig gekrümmt ist und sich wegen Abschnitt 6 in einem hinreichenden Abstand von dem Bremsengehäuse 1 befindet. Durch die halbkreisförmige Krümmung des Abschnitts 7 nähert sich das schlauchseitige Ende des Zwischenrohres 4 einem dritten gekrümmten Abschnitt 8 des Zwischenrohrs 4, der in einen Verbinder 9 übergeht.An embodiment of the invention is explained below with reference to the drawing. The drawing shows sections of a brake caliper housing 1 with a threaded bore 2, into which a union screw 3 serves as a fitting for an intermediate tube 4. The cap screw 3 can be used to screw the end of the intermediate tube 4 facing the brake housing 1 by means of the sealing flange 5 in a pressure-tight manner. A first section 6 of the intermediate tube 4 thus emerges perpendicularly from the brake housing 1. This first section 6 merges into a second section 7, which is semicircularly curved and is located at a sufficient distance from the brake housing 1 because of section 6. Due to the semicircular curvature of the section 7, the hose-side end of the intermediate pipe 4 approaches a third curved section 8 of the intermediate pipe 4, which merges into a connector 9.
Wie in der Zeichnung angedeutet liegt der dritte Abschnitt 8 zumindest teilweise zwischen zwei zueinander parallelen Blöcken 10, deren Abstand der Innenflächen etwa genauso groß ist, wie der Außendurchmesser des Zwischenrohrs 4. Durch den gekrümmten Bereich des Abschnittes 8 zwischen den Blöcken 10 wird ein Drehen des Zwischenrohrs in allen Ebenen verhindert, die nicht parallel zu den beiden Blöcken 10 verlaufen. Die Drehungen in dieser Ebene ist aber wiederum durch die Montage des ersten Abschnittes 6 des Zwischenrohrs 4 im Bremsengehäuse 1 verhindert. Neben dem Zwischenrohr 4 ragt in den Verbinder 9, von der entgegengesetzten Seite kommend, ein Bremsschlauch 11. Als zusätzliche Halterung des Bremsschlauches 11 im Verbinder 9 und zur Versteifung des Bremsschlauches in diesem Bereich ist eine Dichthülse 12 vorgesehen. Durch die versteifende Wirkung der Dichthülse 12 ist es möglich, in dem ringförmigen Gebiet 13 den Hülsenansatz 14 des Verbinders 9 einzusicken und somit den Bremsschlauch 11 in diesem Gebiet zwischen Dichthülse 12 und der äußeren Sicke des Hülsenansatz 14 einzuquetschen.As indicated in the drawing, the third section 8 lies at least partially between two mutually parallel blocks 10, the spacing of the inner surfaces of which is approximately the same as the outer diameter of the intermediate tube 4. The curved area of the section 8 between the blocks 10 causes the Intermediate tube prevented in all levels that are not parallel to the two blocks 10. The rotations in this plane are in turn prevented by the mounting of the first section 6 of the intermediate tube 4 in the brake housing 1. In addition to the intermediate tube 4, a brake hose 11 protrudes into the connector 9, coming from the opposite side. A sealing sleeve 12 is provided as an additional holder for the brake hose 11 in the connector 9 and for stiffening the brake hose in this area. The stiffening effect of the sealing sleeve 12 makes it possible to crimp the sleeve extension 14 of the connector 9 in the annular region 13 and thus to squeeze the brake hose 11 in this region between the sealing sleeve 12 and the outer beading of the sleeve extension 14.
Neu und für die Erfindung wichtig ist, daß die Dichthülse 12 nicht getrennt von dem Zwischenrohr 4 in den Verbinder 9 eingesetzt wird, sondern an diesen einstückig angeformt ist. Entsprechendes gilt für einen Kragen 15, der in eine Stufenbohrung des Verbinders ragt. Der Kragen 15 und damit das Zwischenrohr 8 ist in dem Verbinder mittels einer Verscherung 17 befestigt, die sich ringförmig an die Seitenfläche des Kragens 15 anlegt. Es können aber auch andere unlösbare Verbindungen, wie sicken, bördeln, lancieren oder ähnliches angewendet werden.What is new and important for the invention is that the sealing sleeve 12 is not inserted separately from the intermediate tube 4 into the connector 9, but is integrally formed thereon. The same applies to a collar 15 which projects into a stepped bore of the connector. The collar 15 and thus the intermediate tube 8 is fastened in the connector by means of a shear 17 which lies in a ring on the side surface of the collar 15. However, other non-detachable connections, such as beads, flanges, launches or the like, can also be used.
Eine zusätzliche Befestigung des Zwischenrohrs 4 in den Verbinder 9, ist durch eine ringförmige Verstemmung 18 gegeben, mit der die dem Schlauch abgewandte Stirnseite des Verbinders 9 gegenüber dem Zwischenrohr 4 arretiert wird. An additional fastening of the intermediate tube 4 in the connector 9 is provided by an annular caulking 18, with which the end face of the connector 9 facing away from the hose is locked relative to the intermediate tube 4.
