Abstract
Description
Die Erfindung betrifft eine Radbremse für Kraftfahrzeuge, insbesondere für Personenkraftwagen, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a wheel brake for motor vehicles, in particular for passenger cars, according to the preamble of claim 1.
Es ist bereits bekannt, bei Fahrzeugen mit Scheibenbremsen, die Bremsscheiben durch jeweils ein Schutzblech, welches feststehend zwischen Bremsscheibe und Radträger befestigt ist, abzuschirmen. Dadurch wird die Bremsscheibe und eine evtl. vorhandene Feststelltrommelbremseinheit vor Spritzwasser und Verunreinigungen geschützt.It is already known, in vehicles with disc brakes, the brake discs by a respective fender, which is fixed between brake disc and wheel carrier is attached, shield. This will cause the brake disc and a possibly existing locking drum brake unit from splash water and Protected impurities.
Um einen effektiven Schutz vor Spritzwasser und Schmutz zu erreichen muss das Schutzblech die Bremsscheibe möglichst dicht abdecken. Dies wiederum verhindert eine Luftzufuhr zur Kühlung der Bremsscheibe. Der daraus entstehende Nachteil sind hohe Bremsscheibentemperaturen. Eine größere Dimensionierung der Bremsanlage ist notwendig und ist mit Mehrkosten und einem höheren Gewicht verbunden, bzw. durch den begrenzten Bauraum nicht möglich.Around to achieve effective protection against splash water and dirt the mudguard must cover the brake disc as tight as possible. This in turn prevents an air supply for cooling the brake disc. Of the resulting disadvantages are high brake disc temperatures. A larger dimensioning the brake system is necessary and is associated with additional costs and a higher weight, or not possible due to the limited installation space.
Aus
der
Aufgabe der Erfindung ist es, eine Radbremse für Kraftfahrzeuge bereitzustellen, die einen wirksamen Schutz gegen Spritzwassereintritt besitzt und trotzdem über eine Luftkühlung so effizient gekühlt wird und dadurch eine solche Senkung der Bremsscheibentemperatur erreicht wird, dass sich Gewichts- und Kostenvorteile bereits bei der Auslegung über die Bremsscheibendimensionierung ergeben.task the invention is to provide a wheel brake for motor vehicles, which has an effective protection against splash water entry and still have a air cooling is cooled as efficiently and thereby achieves such a reduction of the brake disc temperature will be that weight and cost advantages already in the interpretation of the Brake disc dimensioning result.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung beschreiben die abhängigen Ansprüche.These The object is solved by the features of claim 1. Further Embodiments of the invention describe the dependent claims.
Nach der Erfindung besteht eine in einer Radfelge angeordnete Radbremse für ein Kraftfahrzeug aus einer Scheibenbremse als Betriebsbremse und einer Trommelbremse als Feststellbremse. Zur fahrzeuginneren Seite hin ist die Radbremse durch eine mit Ausnehmungen zum Kühlluftdurchtritt versehene Schutzabdeckung abgedeckt. Diese ist dadurch gekennzeichnet, dass sich die Ausnehmungen in der Schutzabdeckung auf Höhe des Reibringinnendurchmessers der Bremsscheibe befinden.To The invention consists in a wheel rim arranged in a wheel brake for a Motor vehicle from a disc brake as a service brake and a Drum brake as parking brake. To the vehicle interior side is the wheel brake through one with recesses for cooling air passage covered protective cover. This is characterized that the recesses in the protective cover at the height of the friction ring inside diameter the brake disc are located.
Das hat den Vorteil, dass die Ausnehmungen so positioniert sind, dass der Reibring der Bremsscheibe abgedeckt ist. Dadurch gibt es keine Einschränkung hinsichtlich des Nassansprechverhaltens der Scheibenbremse. Durch die Ausnehmungen kann Luft an und, bei innenbelüfteten Bremsscheiben, in die Bremsscheibe strömen.The has the advantage that the recesses are positioned so that the friction ring of the brake disc is covered. There is no such thing restriction in terms of wet response of the disc brake. By the recesses can air and, in ventilated brake discs, in the Flow brake disk.
Eine bevorzugte Ausführung der Erfindung ist dadurch gekennzeichnet, dass die Trommelbremse in einem Bremsscheibentopf untergebracht ist, der zur fahrzeuginneren Seite hin durch eine Labyrinth-Dichtung vor von außen eintretendem Wasser geschützt ist und einen als Tropfrand ausgebildeten Vorsprung besitzt. Dadurch ist der Bremsscheibentopf vorteilhafterweise so ausgeführt, dass das Wasser von der Feststellbremseneinheit weg, abläuft.A preferred embodiment the invention is characterized in that the drum brake housed in a brake disk pot, which is to the vehicle interior Side through a labyrinth seal before entering from outside Protected water is and has a trained as a drip edge projection. Thereby the brake disk cup is advantageously designed so that the water away from the parking brake unit expires.
Eine weitere bevorzugte Ausführung der Erfindung ist dadurch gekennzeichnet, dass die Labyrinth-Dichtung mindestens durch eine Abdichtnut im Bremsscheibentopf gebildet wird, die einem Haltering für die Bremsbacken einen Überstand ermöglicht. Damit verhindert ein Überstand eines zweiten Bleches, das gleichzeitig als Haltering für die Bremsbacken verwendet werden kann, das Eindringen von Feuchtigkeit.A further preferred embodiment the invention is characterized in that the labyrinth seal is formed at least by a sealing groove in the brake disk hub, a retaining ring for the brake shoes a supernatant allows. This prevents a supernatant a second sheet, which at the same time as a retaining ring for the brake shoes can be used, the penetration of moisture.
Ein bevorzugtes Ausführungsbeispiel der Erfindung beschreibt die nachfolgende Beschreibung mit der zugehörigen Zeichnung. Es zeigen:One preferred embodiment The invention describes the following description with the accompanying drawings. Show it:

fahrzeuginneren Seite hin sind der Bremsscheibentopf
Beziehungsweise, bei gleicher Leistung und gleichem Gewicht, kann die Bremsendimensionierung verkleinert werden, was dann Vorteile bezüglich Gewicht und Kosten bringt.or, with the same power and weight, the brake sizing can be reduced, which then brings advantages in terms of weight and cost.
