Abstract
Description
Die Erfindung bezieht sich auf eine innenbelüftete Bremsscheibe mit zwei gegenüberliegenden Reibringscheiben und zwischen diesen vorgesehenen Belüftungskanälen.The The invention relates to an internally ventilated brake disc with two opposite friction rings and between these provided ventilation channels.
Derartige Bremsscheiben, die beispielsweise in Scheibenbremsen von Kraftfahrzeugen eingesetzt werden, sind aus dem Stand der Technik allgemein bekannt.such Brake discs, for example, in disc brakes of motor vehicles are used, are well known in the art.
Generell besteht an Bremsscheiben das Problem, die beim Bremsen entstehende Abwärme möglichst wirkungsvoll abzuführen. Konventionell belüftete Bremsscheiben sind in ihrer Kühlleistung begrenzt. Um bei heutigen Motorisierungen eine thermisch ausreichende Auslegung zu gewährleisten, müssen vielfach große und aufwendige Radbremsen vorgesehen werden.As a general rule there is a problem with brake discs, which is the result of braking waste heat preferably effectively dissipate. Conventionally ventilated Brake discs are in their cooling capacity limited. In today's engines a thermally sufficient To ensure interpretation need many times size and elaborate wheel brakes are provided.
Ziel der Erfindung ist daher die Schaffung einer innenbelüfteten Bremsscheibe, die sich durch eine hohe Kühlleistung auszeichnet.aim The invention therefore provides for the creation of a ventilated brake disk. which is characterized by a high cooling capacity distinguished.
In diesem Zusammenhang ist es bereits gebräuchlich, die Reibflächen der Reibringscheiben mit Bohrungen zu versehen.In In this context, it is already common, the friction surfaces of To provide friction rings with holes.
Eine
weitere Maßnahme
besteht darin, die Verbindungsabschnitte zwischen den Reibringscheiben,
welche die Belüftungskanäle begrenzen,
als Ventilationsschaufeln auszubilden, wie dies in der
Zudem
ist aus der
Eine weitere Möglichkeit, die Wärmeabfuhr zu erhöhen, besteht darin, die Belüftungskanäle in Durchströmrichtung mit einem wellenförmigen Profil auszubilden und so für eine erhöhte Verwirbelung der Kühlluft zu sorgen.A another possibility the heat dissipation too increase, consists in the ventilation channels in the flow direction with a wavy To train profile and so for an increased Turbulence of the cooling air to care.
In Abgrenzung hierzu sieht die Erfindung gemäß Patentanspruch 1 vor, eine Scheibe zwischen den Reibringscheiben in die Bremsscheibe einzubetten, die in den Belüftungskanälen zusätzliche Kühloberflächen bereitstellt.In Differentiation to this, the invention provides according to claim 1, a To embed the disc between the friction ring discs in the brake disc, which in the ventilation channels additional Provides cooling surfaces.
Hierdurch wird die an der Bremsscheibe insgesamt zur Verfügung stehende Kühloberfläche auf einfache Art und Weise erhöht. Durch die Querschnittsveränderung in den Belüftungskanälen wird überdies ein zusätzlicher Verwirbelungseffekt erzielt, der den konvektiven Wärmeübergang erhöht. Hierdurch kann in vielen Fällen von einer Vergrößerung der radialen Abmessung der Bremsscheibe und der Bremsanlage abgesehen werden.hereby the total available on the brake disc cooling surface is simple Way increased. By the cross-sectional change in the ventilation channels is also an additional one Whirling effect achieved, the convective heat transfer elevated. This can be done in many cases from an enlargement of the Radial dimension of the brake disc and the brake system apart become.
Die erfindungsgemäße Bremsscheibe zeichnet sich zudem durch gute Herstellungseigenschaften aus.The inventive disc is also characterized by good manufacturing properties.
Weitere, vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen angegeben.Further, advantageous embodiments of the invention are specified in the claims.
So ist es beispielsweise möglich, die Scheibe in der Teilungsebene der Belüftungskanäle anzuordnen. Hierdurch wird eine besonders gleichmäßige Kühleleistung erzielt.So is it possible, for example, To arrange the disc in the division plane of the ventilation channels. This will a particularly uniform cooling performance achieved.
Zur weiteren Verbesserung der Verwirbelung kann die Scheibe im Bereich der Belüftungskanäle Öffnungen aufweisen. Auch können an der Scheibe im Bereich der Belüftungskanäle Luftverwirbelungsvorsprünge vorgesehen werden, die gegenüber der Haupterstreckungsebene der Scheibe ausgestellt sind.to Further improving the swirling can be the slice in the field the ventilation channels openings exhibit. Also can provided on the disc in the ventilation ducts Luftverwirungsungsvorsprünge be opposite the main plane of extension of the disc are issued.
Gemäß einer vorteilhaften Ausgestaltung ist die Scheibe ein einfacher gestanzter Blechring, der sich einfach und kostengünstig fertigen lässt. Die vorstehend genannten Öffnungen und Luftverwirbelungsvorsprünge lassen sich hierbei problemlos an der Scheibe anbringen.According to one advantageous embodiment, the disc is a simple punched Sheet metal ring that is easy and inexpensive to manufacture. The above-mentioned openings and air swirl projections can be easily attached to the disc.
Die Scheibe kann beispielsweise in den Bremsscheibenkörper eingegossen werden, wodurch eine innige Verbindung erzielt wird. Vorzugsweise werden hierbei Materialien mit gleichartigen Wärmedehnungseigenschaften verwendet.The Slice can be cast for example in the brake disc body become, whereby an intimate connection is achieved. Preferably In this case, materials with similar thermal expansion properties are used.
In einer weiteren vorteilhaften Ausgestaltung sind die Reibringscheiben durch Ausnehmungen in der Scheibe hindurch miteinander verbunden.In In another advantageous embodiment, the friction rings are connected by recesses in the disc through each other.
Nachfolgend wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Die Zeichnung zeigt in:following the invention will be described with reference to embodiments shown in the drawings explained in more detail. The Drawing shows in:
