Description
Trommelbremsaggregat mit Innenkühlung mit Luftleitflächen, insbesondere für Kraftfahrzeuge Die Erfindung bezieht sich auf Trommelbremsaggregate mit Innenkühlung mit Luftleitflächen, insbesondere für Kraftfahrzeuge.Drum brake unit with internal cooling with air guide surfaces, in particular for motor vehicles The invention relates to drum brake assemblies with internal cooling with air guide surfaces, in particular for motor vehicles.
Es sind Trommelbremsaggregate bekannt, bei denen die Trommelwand mit Luftleitflächen versehen ist, die entweder aus dem Material der Trommelwand herausgedrückt oder als gesonderte Schaufeln in die Trommelwand eingesetzt sind. Weiterhin sind Lösungen bekannt, bei denen die Trommelwand als ein von der Trommel getrenntes Bauteil ausgebildet ist, wobei Luftleitflächen in der Trommelwand angeordnet sind. Diese bekannten Trommelbremsaggregate besitzen jedoch den Nachteil, daß die Anordnung der Luftleitflächen in der Trommelwand kostspielig und technisch aufwendig ist.There are drum brake units known in which the drum wall with Air guide surfaces are provided, which are either pressed out of the material of the drum wall or are used as separate blades in the drum wall. Furthermore are Solutions known in which the drum wall as a separate component from the drum is formed, wherein air guide surfaces are arranged in the drum wall. These known drum brake units have the disadvantage that the arrangement the air guide surfaces in the drum wall is expensive and technically complex.
Diese Nachteile werden erfindungsgemäß dadurch vermieden, daß bei einem Trommelbremsaggregat die Luftleitflächen, wie an sich bekannt, als von der Trommel getrenntes Bauteil ausgebildet sind und dieses Bauteil die Form einer kreisförmigen Blechscheibe aufweist, welche zwischen Trommelwand und Radschüssel angeordnet ist, wobei den Leitflächen in an sich bekannter Weise Durchbrechungen in der Trommelwand zugeordnet sind.These disadvantages are avoided according to the invention in that at a drum brake unit, the air guide surfaces, as known per se, than from the Drum separate component are formed and this component has the shape of a circular Has sheet metal disc, which is arranged between the drum wall and wheel disc, whereby the guide surfaces have openings in the drum wall in a manner known per se assigned.
Die erfindungsgemäße Anordnung stellt eine einfache und unaufwendige Konstruktion dar, die insbesondere im Großserienbau Vorteile bringt, ohne jedoch diese Vorteile mit dem Nachteil einer schlechteren Kühlung erkaufen zu müssen.The arrangement according to the invention is simple and inexpensive Construction that brings advantages, especially in large-scale production, but without having to buy these advantages with the disadvantage of poor cooling.
Bei der erfindungsgemäßen Anordnung braucht im Gegensatz zu bekannten Anordnungen keine komplizierte Ausbildung der Trommelwand in Kauf genommen zu werden. Insbesondere ist es nicht notwendig, verschiedene Trommelausführungen für rechte und linke Fahrzeugräder vorzusehen.In the arrangement according to the invention, in contrast to known ones, needs Arrangements no complicated training of the drum wall to be accepted. In particular, it is not necessary to use different drum designs for right and to provide left vehicle wheels.
Die erfindungsgemäße Konstruktion erlaubt die Anordnung der die Leitflächen tragenden Blechscheibe ohne zusätzliche Befestigungsmittel und ohne einen zusätzlichen Arbeitsgang bei der Montage, da die Scheibe zwischen Bremstrommel und Radschiene eingebaut wird.The construction according to the invention allows the arrangement of the guide surfaces supporting sheet metal disc without additional fasteners and without an additional Assembly process, as the disc is between the brake drum and the wheel rail is installed.
In Ausgestaltung der Erfindung ragen die Leitflächen durch Durchbrechungen in der Trommelwand in das Trommelinnere hinein. Weiterhin können im Inneren der Trommel angeordnete Teile so nahe zur Bewegungsbahn der Leitflächen angeordnet sein, daß sie als Gegenschaufeln wirksam werden.In an embodiment of the invention, the guide surfaces protrude through openings in the drum wall into the inside of the drum. Furthermore, inside the Parts arranged on the drum are arranged so close to the path of movement of the guide surfaces, that they act as counter-blades.
Schutz wird lediglich für die Kombination sämtlicher Merkmale des Hauptanspruchs begehrt. Die Unteransprüche sind echte Unteransprüche und gelten nur in Verbindung mit dem Hauptanspruch.Protection is only given for the combination of all features of the Main claim desired. The subclaims are real subclaims and apply only in connection with the main claim.
Gemäß der Erfindung werden sämtliche Leitflächen einer Bremstrommel durch ein gemeinsames eigenes Bauteil dargestellt, nämlich eine mit entsprechenden Durchdrückungen versehene kreisförmi,ge Blechscheibe. Diese weist ein mit der Trommelwand übereinstimmendes Lochbild auf und wird mit dieser zusammen an der Radnabe befestigt. Die Scheibe liegt somit an der Innenseite der Bremstrommelwand an. In der Bremstrommelwand werden dabei an den entsprechenden Stellen beispielsweise rechteckige Durchbrüche vorgesehen, durch die die Ventilation der Bremse erfolgen kann.According to the invention, all guide surfaces of a brake drum represented by a common component of their own, namely one with a corresponding one Circular sheet metal disc with indentations. This has one with the drum wall matching hole pattern and is attached to the wheel hub together with this. The disc therefore rests against the inside of the brake drum wall. In the brake drum wall For example, rectangular openings are made at the appropriate points provided, through which the ventilation of the brake can take place.
