Description
Die Erfindung bezieht sich auf eine innen belüftete Bremsscheibe nach dem Oberbegriff des Anspruchs 1.The invention relates to an internally ventilated brake disc according to the preamble of claim 1.
Aus der DE-PS 22 57 176 ist eine innenbelüftete Bremsscheibe für eine Scheibenbremse mit Durchgangsbohrungen in den Reibflächen bekannt, bei der in den die Luftkanäle begrenzenden Querrippen ein Umfangsbereich der Durchgangsbohrungen verläuft.From DE-PS 22 57 176 is a ventilated brake disc for one Disc brake with through holes in the friction surfaces known in the the air ribs delimiting a circumferential region of the Through holes runs.
Aufgabe der Erfindung ist es, eine innenbelüftete Bremsscheibe mit radial verlaufenden Luftkanälen zu schaffen, bei der eine Rißbildung im Bereich der Bohrungen unterbunden wird.The object of the invention is to provide an internally ventilated brake disc with radially extending To create air channels in which cracking in the area of the holes is prevented.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the characterizing features of Claim 1 solved. The dependent claims contain further advantageous features.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß durch eine Verstärkung der Bremsscheibe im Bereich von zusätzlichen Bohrungen eine Rißbildung in den Reibflächen der Scheiben vermieden wird. Hierzu sind die zusätzlichen Bohrungen in Verstärkungen, wie Halbrippen oder Zapfen angeordnet. Durch diese Lage der Bohrungen wird der punktuellen Materialschwächung der Bremsscheibe entgegengewirkt.The main advantages achieved with the invention are that by a Reinforcement of the brake disc in the area of additional holes cracking is avoided in the friction surfaces of the discs. Here are the additional ones Bores arranged in reinforcements such as half ribs or tenons. Through this The position of the holes is the selective weakening of the material of the brake disc counteracted.
Die Verstärkungen sind zwischen den einen Luftkanal der Bremsscheibe begrenzenden Querrippen angeordnet, so daß die Durchgangsbohrungen den Freiraum des Kanals durchdringen sind und eine Ergänzung zu den übrigen Durchgangsbohrungen, die teilweise in den Querrippen verlaufen, bilden.The reinforcements are between the one air channel of the brake disc limiting transverse ribs arranged so that the through holes Penetrating the channel's free space and complementing the rest Through holes that partially run in the transverse ribs form.
Die Halbrippen jeder Bremsscheibenseite stehen sich mit einem Luftspalt gegenüber und sind vorzugsweise mittig zwischen den Querrippen des Luftkanals in einer Längsmittenebene angeordnet. The half ribs on each side of the brake disc face each other with an air gap and are preferably in the middle between the transverse ribs of the air duct in one Longitudinal center plane arranged.
Im Bereich der Durchgangsbohrungen sind die Halbrippen mit einer größeren Breite versehen als im übrigen Bereich. Je nach den Erfordernissen ist die Länge und Breite der Halbrippe auslegbar.In the area of the through holes, the half ribs have a larger width provided than in the rest of the area. Depending on the requirements is the length and width the half rib can be laid out.
Nach einer weiteren erfindungsgemäßen Ausführung können die Verstärkungen auch als Zapfen ausgebildet sein. Sie sind im Abstand zueinander angeordnet und verlaufen in der Längsmittenebene des Luftkanals.According to a further embodiment according to the invention, the reinforcements can also be designed as a pin. They are spaced apart and run in the longitudinal center plane of the air duct.
Nach einer weiteren Ausführung können je nach den Erfordernissen eine Kombination von Verstärkungen in Form von Rippen und Zapfen vorgesehen sein. Dies ist erforderlich, wenn beispielsweise an einer Bremsscheibenseite erhöhte Wärmespannungen auftreten oder sonstige Bedingungen es erforderlich machen, daß statt der Halbrippen als Verstärkung Zapfen an dieser Seite verwendet werden.After a further execution, a combination can be made depending on the requirements of reinforcements in the form of ribs and pins. This is required if, for example, increased on one side of the brake disc Thermal stresses occur or other conditions make it necessary that instead of the half-ribs, cones on this side can be used as reinforcement.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben.Embodiments of the invention are shown in the drawing and are in following described in more detail.

Eine innenbelüftete Bremsscheibe 1 einer Scheibenbremsanlage weist zwischen den Reibflächen 3 und 4 radial verlaufende Luftkanäle 5 auf. Diese sind von Querrippen 6 begrenzt und nach außen und innen hin geöffnet. In diesen Querrippen 6 sind mit einem Teil ihres Umfangs Durchgangsbohrungen 7 angeordnet.An internally ventilated brake disc 1 of a disc brake system has radially extending air channels 5 between the friction surfaces 3 and 4 . These are delimited by transverse ribs 6 and open outwards and inwards. Through-holes 7 are arranged in these transverse ribs 6 with part of their circumference.
Zwischen den Querrippen 6 sind Verstärkungen 8, 9 vorgesehen, in denen zusätzliche Durchgangsbohrungen 10 eingebracht sind. Die Verstärkungen sind in Form von Halbrippen 8 oder Zapfen 9 oder Zapfen 9 und Rippen 8 vorgesehen. Die letztere Ausführung ist nicht näher dargestellt. Reinforcements 8 , 9 are provided between the transverse ribs 6 , in which additional through holes 10 are made. The reinforcements are provided in the form of half-ribs 8 or pin 9 or pin 9 and ribs 8 . The latter version is not shown in detail.
Die Halbrippen 8 jeder Bremsscheibenseite 3 und 4 stehen sich mit einem Abstand (Luftspalt a) gegenüber, so daß die Luft zum Kühlen der Bremsscheibe im Luftkanal 5 zirkulieren kann.The half-ribs 8 of each brake disc side 3 and 4 face each other with a distance (air gap a) so that the air for cooling the brake disc can circulate in the air duct 5 .
Die weitere Ausführung gemäß der Fig. 4 bis 6 weist als Verstärkung Zapfen 9 auf, die sich ebenfalls gegenüberstehen und zwischen sich einen Luftspalt a bilden. Die Zapfen sind angeformt bzw. mit der Bremsscheibe gegossen und verlaufen ebenso wie die Halbrippen 8 in einer Mittellängsebene X-X zwischen den beiden Querrippen 6. Die Zapfen 9 sind im Durchmesser so ausgeführt, daß die Bohrung 10 keine Schwächung der Bremsscheibe mit sich bringt.The further embodiment according to FIGS. 4 to 6 has pegs 9 as reinforcements, which also face each other and form an air gap a between them. The pins are formed or cast with the brake disc and, like the half-ribs 8, run in a central longitudinal plane XX between the two transverse ribs 6 . The pins 9 are designed in diameter so that the bore 10 does not weaken the brake disc.
Die Zapfen 9 und die Halbrippen 8 können in einer Bremsscheibe kombiniert sein, so daß beispielsweise eine Bremsscheibenseite Halbrippen 8 und die andere Bremsscheibenseite Zapfen 9 aufweist.The pin 9 and the half ribs 8 can be combined in a brake disc, so that, for example, one brake disc side has half ribs 8 and the other brake disc side has pin 9 .
Die dargestellte innenbelüftete Bremsscheibe 1 weist radiale und evolventenförmige Luftkanäle 5 auf, in denen die Verstärkungen 8, 9 entsprechend dem Verlauf der Luftkanäle 5 angeordnet sind.The internally ventilated brake disc 1 shown has radial and involute-shaped air channels 5 , in which the reinforcements 8 , 9 are arranged in accordance with the course of the air channels 5 .
