Die Erfindung betrifft eine Bremsscheibe für Fahrzeugbremsen, insbesondere Bremsen für Kraftfahrzeuge und Schienenfahrzeuge. Darüber hinaus ist die erfindungsgemäße Bremsscheibe für Fiugzeugbremsen geeignet.The invention relates to a brake disc for vehicle brakes, in particular brakes for motor vehicles and rail vehicles. In addition, the brake disc according to the invention is suitable for aircraft brakes.
In einer Scheibenbremse wirkt eine mit der Achse verbundene Bremsscheibe mit zumindest einem ortsfest angeordneten Reibpartner, in der Regel einer Bremsbacke, zusammen. Die Werkstoffeigenschaften von Bremsscheibe einerseits und Bremsbacke andererseits sind so ausgewählt, daß der durch die Reibung zwischen beiden entstehende Abrieb bei der Bremsbacke auftritt. Diese läßt sich als Verschleißteil verhältnismäßig leicht austauschen. Es ist aber festzustellen, daß auch bei der Bremsscheibe Abrieb auftritt. Durch den Abrieb wird die Jeweilige Seitenfläche der Bremsscheibe uneben, so daß eine ausgetauschte Bremsbacke zunächst punktueli an der Bremsscheibe angreift, bis die Bremsbacke auf das Profil der Seitenfläche abgerieben worden ist. Dies führt zu einer unerwünschten öunktuellen mechanische Belastung und einer lokalen Überhitzung der Reibpartner. Aufgrund des Abriebs muß schließlich auch die Bremsscheibe ausgetauscht werden, was mit einem erheblichen Aufwand verbunden ist.In a disc brake, a brake disc connected to the axle interacts with at least one stationary friction partner, usually a brake shoe. The material properties of the brake disc on the one hand and the brake shoe on the other are selected so that the abrasion caused by the friction between the two occurs on the brake shoe. As a wearing part, this can be replaced relatively easily. However, it can be seen that abrasion also occurs on the brake disc. The abrasion causes the respective side surface of the brake disc to become uneven, so that a replaced brake shoe initially attacks the brake disc at certain points until the brake shoe has been rubbed down onto the profile of the side surface. This leads to an undesirable, immediate mechanical load and local overheating of the friction partners. Due to the abrasion, the brake disc must also be replaced, which involves considerable effort.
Der Erfindung liegt die A u f g a b e zugrunde, eine Bremsscheibe mit erhöhter Standzeit zu schaffen.The invention is based on the task of creating a brake disc with an increased service life.
Die erfindungsgemäße Bremsscheibe ist dadurch gekennzeic h e &eegr; t, daß die mit jeweils einer Bremsbacke zusammenwirkende Seitenfläche der Bremsscheibe mit Titannitrid (TiN) beschichtet ist.The brake disc according to the invention is characterized in that the side surface of the brake disc which interacts with a brake shoe is coated with titanium nitride (TiN).
Durch die Beschichtung mit Titannitrid (TiN) wird die Verschleißfestigkeit der Bremsscheibe erhöht. An der Bremsscheibe tritt auch bei längerem Einsatz nahezu kein Verschleiß auf. Die erfindungsgemäße Bremsscheibe hat somit eine höhere Standzeit als die im Stand der Technik bekannten Bremsscheiben. Dies ist insbesondere bei solchen Fahrzeugen, wie beispielsweiseThe titanium nitride (TiN) coating increases the wear resistance of the brake disc. There is almost no wear on the brake disc even after long periods of use. The brake disc according to the invention therefore has a longer service life than the brake discs known in the prior art. This is particularly important for vehicles such as, for example,
Lokomotiven, von Interesse, bei denen für einen wirtschaftlichen Betrieb kurze Wartung- und Reparaturzeiten gewünscht werden.Locomotives of interest where short maintenance and repair times are desired for economical operation.
Da bei der erfindungsgemäßen Bremsscheibe die Seitenfläche mit TiN beschichtet ist, bleibt diese eben, so daß eine punktueHe mechanische Betastung bzw. eine tokaie Überhitzung der Reibpartner verhindert wird Die erfindungsgemäße Bremsscheibe kann aus Eisen, Stahl oder Nicht-Eisen-Metaüen hergestellt sein, da die genannten Werkstoffe sich als Substrat für die Beschichtung mit TjN eignen. Seide Seitenflächen der Bremsscheibe gemäß der Erfindung können mit TiN beschichtet sein.Since the side surface of the brake disc according to the invention is coated with TiN, it remains flat, so that a point-like mechanical contact or sudden overheating of the friction partners is prevented. The brake disc according to the invention can be made of iron, steel or non-ferrous metals, since the materials mentioned are suitable as a substrate for the TiN coating. Both side surfaces of the brake disc according to the invention can be coated with TiN.
