Description

Herstellverfahren für eine BremsschlauchverdrehsicherungManufacturing process for a brake hose rotation lock
Die Erfindung betrifft eine Bremsschlauchverdrehsicherung an einem Scheibenbremssattel gemäß dem Oberbegriff des Patent¬ anspruchs 1.The invention relates to a brake hose rotation lock on a disc brake caliper according to the preamble of claim 1.
Ein gattungsgemäßer Scheibenbremssattel mit Bremsschlauch¬ verdrehsicherung ist in der Offenlegungsschrift DE 42 43 183 AI erläutert. Der Bremssattel, der zum Andruck von Bremsbe¬ lägen an eine Bremsscheibe bestimmt ist und für diesen Zweck mit einer hydraulischen Betätigungsvorrichtung ausgestattet ist, die üblicherweise aus einem Bremszylinder und einem im Bremszylinder axial verschiebbar angeordneten Bremskolben besteht. Bei Verwendung solcher Scheibenbremsen für die Rä¬ der von Kraftfahrzeugen ist die hydraulische Betätigungsvor¬ richtung jeweils über eine Hydraulikleitung mit einem zen¬ tralen Druckgeber verbunden. Der Druckgeber besteht übli¬ cherweise aus einem mittels eines Bremspedals betätigten Hauptbremszylinder. Da die Räder des Kraftfahrzeugs wegen der Federung und der Lenkung gegenüber der Karosserie beweg¬ lich sind, ist die Hydraulikleitung teilweise als flexibler Bremsschlauch ausgebildet. Bei einer gattungsgemäßen Schei¬ benbremse ist nun der Bremsschlauch an seinem Ende mit einem Ringstutzen versehen, der mittels einer Hohlschraube, die in eine Versorgungsbohrung des BremsZylinders eingeschraubt ist, an die hydraulische Betätigungsvorrichtung angeschlos¬ sen. Dabei steht die Schlauchachse im wesentlichen senk¬ recht auf der Schraubenachse, so daß der Bremsschlauch seit¬ lich vom Ringstutzen wegführt. Bei einer solchen Anordnung besteht jedoch die Gefahr, daß bei Bewegung des Bremsschlau¬ ches ein Drehmoment auf den Ringstutzen ausgeübt wird, die¬ ser um die Schraubenachse gedreht wird und die Hohlschraube gelockert wird. Unter ungünstigen Umständen können dadurch Undichtigkeiten im Hydrauliksystem entstehen und zum Ausfall der Bremse führen. Daher ist der Ringstutzen durch form¬ schlüssige, seitliche Anlage an einem angegossenen Vorsprung bzw. einem eingebrachten Spannstift gegen eine Drehbewegung gesichert. Allerdings läßt ein angegossener Vorsprung auf¬ grund hoher Toleranzschwankungen in der Regel noch recht große Verdrehwinkel zu. Der Nachteil der Verwendung eines Spannstiftes liegt in dem zusätzlichen Teileaufwand, der Erfordernis einer zusätzlichen Bohrung und der unzureichen¬ den Sicherheit gegen Verlust des Spannstiftes.A generic disc brake caliper with anti-rotation lock is explained in the published patent application DE 42 43 183 AI. The brake caliper, which is intended for pressing brake linings against a brake disc and is equipped for this purpose with a hydraulic actuation device, which usually consists of a brake cylinder and a brake piston arranged axially displaceably in the brake cylinder. When such disc brakes are used for the wheels of motor vehicles, the hydraulic actuating device is each connected to a central pressure transmitter via a hydraulic line. The pressure transmitter usually consists of a master brake cylinder actuated by means of a brake pedal. Since the wheels of the motor vehicle are movable relative to the body because of the suspension and the steering, the hydraulic line is partially designed as a flexible brake hose. In the case of a generic disc brake, the brake hose is now provided at its end with an annular connector which is connected to the hydraulic actuating device by means of a hollow screw which is screwed into a supply bore of the brake cylinder. The hose axis is essentially perpendicular to the screw axis, so that the brake hose leads away from the ring connector. With such an arrangement, however, there is the risk that when the brake hose is moved, a torque is exerted on the ring connector, which is rotated about the screw axis and the hollow screw is loosened. Under unfavorable circumstances, this can lead to leaks in the hydraulic system and lead to brake failure. Therefore, the ring connector is secured against rotational movement by form-fitting, lateral contact with a cast-on projection or an inserted dowel pin. However, due to high tolerance fluctuations, a cast-on protrusion generally permits quite large angles of rotation. The disadvantage of using a dowel pin lies in the additional expenditure on parts, the need for an additional hole and the inadequate security against loss of the dowel pin.
Aufgabe der Erfindung ist es ein Herstellungsverfahren für eine Bremsschlauchverdrehsicherung anzugeben, daß eine ko¬ stengünstige, integrierte und verliersichere Ausführung ei¬ ner Verdrehsicherung für den Ringstutzen bzw. Bremsschlauch am Bremssattel liefert.The object of the invention is to provide a manufacturing method for a brake hose anti-rotation device that provides a cost-effective, integrated and captive version of an anti-rotation device for the ring connector or brake hose on the brake caliper.
Die Lösung der Aufgabe ergibt sich aus dem kennzeichnenden Teil des Patentanspruchs 1. Im Prinzip besteht die Lösung in der Verwendung eines Spezialwerkzeuges, das aus einer am Bremssattelrohteil vorgehaltenen Gußnoppe in einem spanenden Bearbeitungsgang direkt einen Vorsprung zur formschlüssigen Anlage des Ringstutzens erzeugt.The solution to the problem arises from the characterizing part of patent claim 1. In principle, the solution consists in the use of a special tool which, in a machining process step, directly produces a projection from the cast nub on the brake caliper raw part for positive engagement of the ring connector.
In einer bevorzugten Ausführungsform der Erfindung besteht das eingesetzte Spezialwerkzeug aus einem Hohlsenker, der zwischen seinen Schneiden einen Hohlraum besitzt, der mit der Kontur des gewünschten Vorsprungs am Bremssattel über¬ einstimmt. In einfacher Weise läßt sich der Vorsprung mit einem solchen Hohlsenker gemäß Anspruch 3 als zylindrischer Zapfen ausbilden. Ein Ausführungsbeispiel der Erfindung wird im folgenden an¬ hand der Zeichnung in vier Figuren erläutert.In a preferred embodiment of the invention, the special tool used consists of a countersink, which has a cavity between its cutting edges, which corresponds to the contour of the desired projection on the brake caliper. The projection can be designed in a simple manner with such a countersink as a cylindrical pin. An embodiment of the invention is explained below with reference to the drawing in four figures.

In den Figuren 1 bis 3 ist ein Bremssattel 1 mit einer hy¬ draulischen Betätigungsvorrichtung 2 gezeigt, der über eine am Bremssattel integrierte Bremsschlauchverdrehsicherung 5 verfügt. Mit einer in Figur 3 gezeigten Hohlschraube 3 ist der flexible Bremsschlauch 4, der mit einem nicht gezeigten zentralen Druckgeber in Verbindung steht, über einen Rings¬ tutzen 6 innerhalb einer Versorgungsbohrung 7 am Bremssattel 1 befestigt.1 to 3 show a brake caliper 1 with a hydraulic actuating device 2, which has a brake hose rotation lock 5 integrated on the brake caliper. With a hollow screw 3 shown in FIG. 3, the flexible brake hose 4, which is connected to a central pressure transmitter, not shown, is fastened to the brake caliper 1 within a supply bore 7 via a ring connector 6.
Um ein Verdrehen des Ringstutzens 6 um die Achse der Versor¬ gungsbohrung 7 und daraus möglicherweise resultierende Un¬ dichtigkeiten im Hydrauliksystem zu verhindern, ist eine erfindungsgemäß erzeugte, integrierte Bremsschlauchverdreh¬ sicherung 5 vorgesehen. Diese ist unter Einsatz eines Son- derwerkzeuges, vorzugsweise eines Hohlsenkers 8 gemäß Figur 5, direkt am Bremssattel 1 realisiert. Dazu wird eine am Rohteil des Bremssattels angeformte nicht gezeigte vorste¬ hende Gußnoppe, die sich in unmittelbarer Nähe der hydrau¬ lischen Versorgungsbohrung 7 befindet, mit einem Hohlsenker 8 aus Figur 5 spanend bearbeitet. Es verbleibt nach diesem Bearbeitungsschritt als Vorsprung auf dem Bremssattel ein zylindrischer Zapfen 9, der einem entsprechend, passend aus¬ geführten Ansatz 10 am Ringstutzen 6 als formschlüssige An¬ lage dient. Gegenüber einer Bremsschlauchverdrehsicherung mit eingesetztem Spannstift entfällt hier das Einbringen der Spannstiftbohrung, der Arbeitsgang des Einsetzens des Spann¬ stiftes und weiterhin ist mit dem Spannstift kein zusätzli¬ ches Bauteil erforderlich. Außerdem ist das Problem des Ver- lierens des Spannstiftes und somit des Versagens der Ver¬ drehsicherung durch die integrierte Bauform des Zapfens 9 direkt am Bremssattel 1 beseitigt. Im Vergleich zu einem angegossenen Vorsprung als Anlagefläche für den Ringstutzen besitzt der spanend bearbeitete Zapfen 9 eine weitaus höhere Maßgenauigkeit und läßt damit nur einen geringeren Verdreh¬ winkel des Ringstutzens 6 zu. Daher ergibt sich neben dem Kosten- auch ein Qualitätsvorteil.In order to prevent twisting of the ring stub 6 about the axis of the supply bore 7 and possibly resulting leaks in the hydraulic system, an integrated brake hose twist lock 5 produced according to the invention is provided. This is done using a special der tool, preferably a countersink 8 according to Figure 5, realized directly on the brake caliper 1. For this purpose, a protruding cast nub, not shown, which is formed on the raw part of the brake caliper and is located in the immediate vicinity of the hydraulic supply bore 7, is machined with a countersink 8 from FIG. After this processing step, there remains as a projection on the brake caliper a cylindrical pin 9, which serves as a form-fitting system for a corresponding, appropriately designed attachment 10 on the ring connector 6. Compared to a brake hose anti-twist device with inserted dowel pin, there is no need to insert the dowel pin bore, the operation of inserting the dowel pin, and furthermore no additional component is required with the dowel pin. In addition, the problem of losing the dowel pin and thus failure of the anti-rotation device is eliminated by the integrated design of the pin 9 directly on the brake caliper 1. Compared to a cast-on projection as a contact surface for the ring socket, the machined pin 9 has a much higher dimensional accuracy and thus allows only a smaller angle of rotation of the ring socket 6. Therefore, in addition to the cost, there is also a quality advantage.
In Figur 3 ist der an der hydraulischen Betätigungsvorrich¬ tung 2 angeschlossene Bremsschlauch 4 mit Ringstutzen 6 in einer vergrößerten teilgeschnittenen Abbildung dargestellt. Die Bremsschlauchverdrehsicherung 5 wird dadurch realisiert, daß ein seitlicher Ansatz 10 am Ringstutzen mit U-förmiger Kontur den zylindrischen Zapfen 9 am Bremssattel formschlüs¬ sig umgreift und eine Drehbewegung um die Achse der Versor¬ gungsbohrung 7 verhindert.FIG. 3 shows the brake hose 4 connected to the hydraulic actuating device 2 with an annular connector 6 in an enlarged, partially sectioned illustration. The brake hose anti-rotation device 5 is realized in that a lateral extension 10 on the ring socket with a U-shaped contour positively engages around the cylindrical pin 9 on the brake caliper and prevents a rotational movement about the axis of the supply bore 7.
Figur 4 zeigt einen zur Bremsschlauchverdrehsicherung 5 aus Figur 3 passenden Ringstutzen 6, der am Ende des Brems- Schlauches 4 befestigt ist und im Einbauzustand mit seinem U-förmigen, seitlichen Ansatz 10 den zylindrischer Zapfen 9 umgreift .FIG. 4 shows a ring connector 6 which fits to the brake hose rotation lock 5 from FIG. 3 and which at the end of the brake Hose 4 is attached and in the installed state with its U-shaped, lateral approach 10 engages around the cylindrical pin 9.
In einer weiteren nicht gezeigten Ausfürungsform ist auch vorstellbar einen seitlichen Ansatz am Ringstutzen 6 mit einer Bohrung zu versehen, wodurch der Zapfen 9 im Einbau¬ zustand auf seinem vollen Umfang vom Ringstutzenansatz 10 umrandet wird.In a further embodiment, not shown, it is also conceivable to provide a side attachment on the ring connector 6 with a bore, as a result of which the pin 9 is surrounded by the ring connector attachment 10 over its entire circumference in the installed state.
In Figur 5 ist ein als Hohlsenker 8 ausgebildetes Spezial- werkzeug abgebildet. Dieser Hohlsenker 8 ist in der Lage in einem einzigen Bearbeitungsgang aus der am Bremssattel vor¬ gehaltenen Gußnoppe einen maßgenauen Vorsprung in Form eines Zapfens 9 zur formschlüssigen Anlage des Ringstutzensansat¬ zes 10 spanend herzustellen. Dabei erfolgt dieser Bearbei¬ tungsgang mit der gleichen Einstellung der Werkzeugmaschine, die auch zur Erzeugung der Versorgungsbohrung 7 und der An¬ lagefläche 11 des Ringstutzens am Brems-sattel erforderlich ist. Im einzelnen besitzt der Hohlsenker 8 zwischen seinen Schneiden 12 einen Hohlraum 13, der exakt der gewünschten Kontur des Zapfens 9 entspricht.FIG. 5 shows a special tool designed as countersink 8. This countersink 8 is capable of producing a dimensionally accurate projection in the form of a pin 9 for the positive engagement of the ring connecting piece 10 in a single machining step from the cast knob held on the brake caliper. This machining operation takes place with the same setting of the machine tool, which is also required for producing the supply bore 7 and the contact surface 11 of the ring connector on the brake caliper. In particular, the countersink 8 has between its cutting edges 12 a cavity 13 which corresponds exactly to the desired contour of the pin 9.
Durch Umgestaltung des SpezialWerkzeuges lassen sich noch andere Vorsprungskonturen erzeugen, die eine formschlüssige Verbindung zwischen Ringstutzen 6 und bearbeitetem Vor¬ sprung am Bremssattel 1 gewährleisten. By redesigning the special tool, other projection contours can be produced which ensure a positive connection between the ring connector 6 and the machined projection on the brake caliper 1.
