Description
Die Erfindung betrifft eine Festsattel-Teilbelagscheibenbremse für Kraftfahrzeuge mit radial entnehmbaren Bremsklötzen, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a fixed caliper partial brake disc brake for motor vehicles with radially removable brake pads, according to the preamble of claim 1.
Eine gattungsgemäße Scheibenbremse ist in der DE 41 10 869 A1 vorgeschlagen worden. Bei der vorge schlagenen Scheibenbremse sind die zur Führung der Bremsbacken vorgesehenen Stege einstückig mit dem Bremsengehäuse gegossen. Sie bestehen daher zwangsläufig aus demselben Material wie das Bremsengehäuse. Die Stege werden durch die beim Bremsen auf tretenden Umfangskräfte stark belastet und sind Korrosionsein flüssen ausgesetzt. Wenn der Festsattel aus konstruktiven Grün den aus einem nicht hochfesten oder nicht korrosionsbeständigen Material gegossen ist, treten an den Stegen Funktionsmängel auf.A generic disc brake is in the DE 41 10 869 A1 has been proposed. In the pre disc brakes are used to guide the brake shoes provided webs integrally cast with the brake housing. They therefore necessarily consist of the same material as that Brake housing. The webs are due to when braking circumferential forces are heavily loaded and are corrosion exposed to rivers. If the fixed saddle made of constructive green that of a not high-strength or not corrosion-resistant Material is poured, functional defects occur on the webs on.
Des weiteren ist aus der DE 28 09 729 A1 eine Zangenscheiben bremse bekannt, bei der die Bremsbeläge an sich in Achsrichtung der Bremsscheibe erstreckenden Haltestiften verschiebbar aufge nommen sind. Die Haltestifte dienen dabei auch zur Übertragung der Bremsumfangskräfte. Der robuste Gesamtaufbau dieser Zangen scheibenbremse erfordert einen großen Bauraum und erweist sich als nachteilig hinsichtlich der Montage. Insbesondere der Bremsbelagwechsel ist nur aufwendig möglich.Furthermore, from DE 28 09 729 A1 a pliers washer Brake known in which the brake pads themselves in the axial direction the brake disc extending holding pins slidably are taken. The holding pins are also used for transmission the circumferential braking forces. The robust overall structure of these pliers disc brakes require a large amount of installation space and prove themselves as a disadvantage in terms of assembly. Especially the Changing the brake pads is only possible with great effort.
Daraus ergibt sich die Aufgabe, eine gattungsgemäße Teilbelag scheibenbremse mit hinsichtlich Abrieb, Korrosion und Belast barkeit verbesserten Stegen anzugeben.This gives rise to the task of a generic partial covering disc brake with regard to abrasion, corrosion and load availability of improved webs.
Die Lösung der Aufgabe ergibt sich aus dem Patentanspruch 1. Die erfindungsgemäßen Bolzen bestehen aus einem hochfesten Material und haben daher den Vorteil, daß sie stark belastbar sind und geringen Abrieb aufweisen, ohne daß der Festsattel selbst aus einem solchen Material bestehen muß.The solution to the problem arises from the Claim 1. The bolts according to the invention exist made of a high-strength material and therefore have the Advantage that they are strong and low abrasion have without the fixed saddle itself from such Material must exist.
Beispielsweise kann der Festsattel gemäß Anspruch 2 aus Leichtmetall bestehen, wodurch das Gewicht der Bremse erheblich reduziert wird. In einer bevorzugten Ausführungsform gemäß Anspruch 3 besteht der Festsattel aus Aluminiumguß und die Bolzen aus Edelstahl, wodurch Korrosion praktisch ausgeschlossen ist.For example, the fixed caliper according to claim 2 Alloy are made, which reduces the weight of the brake is significantly reduced. In a preferred one Embodiment according to claim 3, the fixed saddle consists of Cast aluminum and stainless steel bolts, causing corrosion is practically excluded.
Eine besonders einfache und kostengünstige Befestigung der Bolzen ergibt sich aus Anspruch 4.A particularly simple and inexpensive attachment of the Bolt results from claim 4.
Zur Verbesserung der Betriebssicherheit der Bremse wird eine Ausgestaltung der Bremsbackenführungen gemäß einem der Ansprüche 5 bis 7 empfohlen. Der Abstand zwischen den Nasen und den Flächen der Bolzen, gemäß Anspruch 7, ermöglicht kleine Relativbewegungen, durch die sich die Bremsbackenführungen von anhaftenden Korrosionsprodukten befreien können.To improve the operational safety of the brake, a Design of the brake shoe guides according to one of the Claims 5 to 7 recommended. The distance between the noses and the surfaces of the bolts, according to claim 7 small relative movements through which the Brake shoe guides of adhering corrosion products can free.
Ein Ausführungsbeispiel einer erfindungsgemäßen Bremsbackenführung wird nachfolgend anhand der Zeichnungen näher erläutert.An embodiment of an inventive Brake shoe guide is based on the drawings explained in more detail.

Bei dem in den Fig. 1 bis 3 dargestellten Ausführungsbeispiel erkennt man eine von zwei Bremsbacken 41, die jeweils aus einer Trägerplatte 42 und einem mit einem Reibbelag 43 versehenen Bremsklotz 44 bestehen, der auf der Trägerplatte 42 lösbar befestigt ist. Die Trägerplatte 42 ist mit zwei Vorsprüngen 45 versehen (in den Figuren ist nur einer sichtbar), mittels derer die Bremsbacken 41 am Festsattel 46 axial verschiebbar geführt sind.In the embodiment shown in FIGS. 1 to 3, one can see one of two brake shoes 41 , each consisting of a carrier plate 42 and a brake pad 44 provided with a friction lining 43 , which is releasably attached to the carrier plate 42 . The carrier plate 42 is provided with two projections 45 (only one is visible in the figures), by means of which the brake shoes 41 are guided axially displaceably on the fixed caliper 46 .
Zur Führung der Bremsbacken 41 ist der Festsattel 46 mit vier Bolzen 47 versehen, die jeweils einen ersten Abschnitt 48 und einen freien, zweiten Abschnitt 49 aufweisen. Die Bolzen 47 sind mit ihrem ersten Abschnitt 48 in Bohrungen 50 des Sattelgehäuses eingepreßt. Der zweite Abschnitt 49 ist mit Abstützflächen 51, 52 versehen, an denen ein Vorsprung 45 axial verschiebbar anliegt.To guide the brake shoes 41 , the fixed caliper 46 is provided with four bolts 47 , each of which has a first section 48 and a free, second section 49 . The bolts 47 are pressed with their first section 48 into bores 50 of the saddle housing. The second section 49 is provided with support surfaces 51 , 52 on which a projection 45 bears axially displaceably.
Zur Sicherung gegen Ausheben der Bremsbacken 41 aus ihren Führungen sind die Vorsprünge 45 mit Nasen 53 versehen, die in axial verlaufende Ausnehmungen 54 der Bolzen 47 eingreifen. Zwischen den Nasen 53 und den Flächen 55 der Ausnehmungen 54 ist ein kleiner Abstand von ungefähr 1 mm vorgesehen, um eine Relativbewegung zu ermöglichen, durch die eine Säuberung der Flächen 55 oder der Nasen 53 von Korrosionsprodukten erfolgt.To prevent the brake shoes 41 from being lifted out of their guides, the projections 45 are provided with lugs 53 which engage in axially extending recesses 54 in the bolts 47 . A small distance of approximately 1 mm is provided between the lugs 53 and the surfaces 55 of the recesses 54 in order to allow a relative movement, by means of which the surfaces 55 or the lugs 53 are cleaned of corrosion products.
