Description
"Vorrichtung zum Kühlen von Scheibenbremsen" Die Erfindung betrifft eine Vorrichtung zum Kühlen von Scheibenbremsen an Fahrzeugen, insbesondere Personenkraftwagen, mit geschlossenen Rädern."Apparatus for Cooling Disc Brakes" The invention relates to a device for cooling disc brakes on vehicles, especially passenger cars, with closed wheels.
Es ist bekannt, daß die Bremsen insbesondere leistungsstarker Kraftwagen so angeordnet werden müssen, daß eine ausreichende Kühlung derselben durch daran vorbeistreichende Luft erfolgt.It is known that the brakes are particularly useful in powerful motor vehicles must be arranged so that sufficient cooling of the same through it passing air takes place.
Es sind deshalb bereits Räder vorgeschlagen worden, die verschiedenartige Durchbrechungen aufweisen, um einen Durchtritt von Luft durch die Räder in den Bereich der Bremsen zu ermöglichen.It has therefore already been proposed wheels, the various Have openings to allow air to pass through the wheels into the area to allow the brakes.
Für mit Durchbrechungen versehene Räder sind auch bereits Radkappen vorgeschlagen worden, die schaufelartige Auspragungen aufweisen, durch die eine Luftförderung zur Kühlung der Bremsen erreicht werden soll.For wheels with openings there are also hubcaps have been proposed that have blade-like features through which a Air delivery to cool the brakes should be achieved.
Nachteilig bei diesen bekannten Anordnungen ist, daß die Räder diese Durchbrechungen aufweisen müssen, wodurch ihre Herstellung verteuert und erschwert werden kann.The disadvantage of these known arrangements is that the wheels this Must have openings, which makes their production more expensive and difficult can be.
Der vorliegenden Erfindung lag demgegenüber die Aufgabe zugrunde, eine ausreichende Kühlluftbeaufschlagung von Scheibenbremsen auch bei geschlossenen, also nicht mit Durchbrechungen versehenen Rädern mit möglichst einfachen Mitteln sicherzustellen.In contrast, the present invention was based on the object a sufficient supply of cooling air to disc brakes even when they are closed, so wheels not provided with openings with the simplest possible means to ensure.
Es wird deshalb eine Vorrichtung zum Kühlen von Scheibenbremsen an Fahrzeugen, insbesondere Personenkraftwagen, mit geschlossenen Rädern, bei denen die innere Seite der Bremsscheibe durch ein Abdeckblech geschützt ist, vorgeschlagen, wobei erfindungsgemäß die Radschüssel im Bereich ihres größten Durchmessers mit einer umlaufenden, nach innen offenen Ausbauchung versehen ist, in der radial angeordnete Schaufeln vorgesehen sind, und wobei das Abdeckblech ein über die Bremsscheibe hinweg in den Raum zwischen Bremsscheibe und Radschüssel reichendes, der Luftführung dienendes Verlängerungsteil aufweist.It is therefore a device for cooling disc brakes Vehicles, in particular passenger cars, with closed wheels, in which the inner side of the brake disc is protected by a cover plate, proposed wherein according to the invention the wheel disc in the area of its largest diameter with a circumferential, inwardly open bulge is provided, in the radially arranged Blades are provided, and wherein the cover plate one over the brake disc that reaches into the space between the brake disc and the wheel disc and serves to guide the air Has extension part.
Die freie Seite des Verlängerungsteiles ist dabei vorzugsweise etwa auf der halben ilöhe der Schaufeln in Richtung der Drehachse des Rades abgebogen.The free side of the extension part is preferably about bent at half the height of the blades in the direction of the axis of rotation of the wheel.
Weiterhin ist es aus strömungstechnischen Gründen vorteilhaft, wenn die Höhe der beiden zwischen Bremsscheibe und Felgenbett gebildeten Kanäle etwa gleich ist.Furthermore, it is advantageous for fluidic reasons if the height of the two channels formed between the brake disc and the rim well approximately is equal to.
Bei einer derartigen Anordnung wird kohle Luft am Innendurchmesser des Abdeckbleches angesaugt. Die I,uft umströmt dann die heiße Bremsscheibe von beiden Seiten, wird durch die in der Radschüssel angeordneten Schaufeln umgelenkt und tritt schließlich zwischen dem als Seite blech dienenden Ve rlängerungsteil des Abdeckblechs und dem Felgenbett ins Freie aus.With such an arrangement, there is carbon air at the inner diameter of the cover plate sucked in. The air then flows around the hot brake disc both sides, is deflected by the blades arranged in the wheel disc and finally occurs between that as a side sheet serving Ve Extension part of the cover plate and the rim base to the outside.
Der Gegenstand der Erfindung soll im folgenden anhand eines in der beiliegenden Zeichnung dargestellten Ausftihrungsbeispiels näher erläutert werden. In der Zeichnung zeigen Fig. 1 eine erfindungsgemäße Anordnung rnit Blick auf die Innenseite des Rades, und Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1 in größerem Maßstab.The object of the invention is to be based on one in the Embodiment example shown in the accompanying drawing will be explained in more detail. In the drawing, FIG. 1 shows an arrangement according to the invention with a view to FIG Inside of the wheel, and FIG. 2 shows a section along the line II-II of FIG. 1 in larger scale.
Die Radschüssel 1 weist in ihrem an das Felgenbett 2 grenzenden Bereich eine umlaufende, nach innen offene Ausbauchung 3 auf, in der - gleichmäßig über den Umfang verteilt - radiale Schaufeln 4 befestigt sind. Die Bremsscheibe 5 ist an ihrer inneren, dem Fahrzeug zugekehrten Seite durch ein Abdeckblech 6 geschützt. Mit dem Abdeckblech 6 verbunden ist ein Verlängerungsteil 7, wodurch getrennte Kanäle für die zu- und abströmende Luft gebildet werden.The wheel disc 1 has in its area bordering the rim base 2 a circumferential, inwardly open bulge 3 in which - evenly across distributed around the circumference - radial blades 4 are attached. The brake disc 5 is protected on its inner side facing the vehicle by a cover plate 6. An extension part 7 is connected to the cover plate 6, thereby creating separate channels for the incoming and outgoing air.
Die I.uftströmungen sind in der Zeichnung jeweils mit Pfeilen angedeutet,The air currents are indicated in the drawing with arrows,
