Abstract

Friction disk with central axis and concentric friction zone, in which effective surface of friction zone is not flat, but is enlarged by a radial shaping concentric with the central axis. There are annular grooves (12) of arc-shaped profile concentric with the central axis in the surface of the friction zone.

Description

Die Erfindung betrifft eine Reibscheibe mit einer Mittelachse und einer dazu konzentrischen Reibzone.The invention relates to a friction disc with a central axis and a concentric friction zone.

Eine solche Reibscheibe ist als Bremsscheibe oder Kupplungs­ scheibe aus der Praxis bekannt. Die Reibzone der Scheibe ist herkömmlicherweise eben.Such a friction disc is used as a brake disc or clutch known from practice. The friction zone of the disc is conventionally just.

Aufgabe der Erfindung ist es, eine Reibscheibe mit verbesserten Eigenschaften zu schaffen.The object of the invention is to provide a friction disc with improved To create properties.

Diese Aufgabe wird mit einer Reibscheibe der eingangs genannten Art dadurch gelöst, daß die wirksame Oberfläche der Reibzone nicht eben, sondern durch eine zu der Mittelachse konzentrische radiale Profilierung vergrößert ist. This task is done with a friction disc of the type mentioned Kind solved in that the effective surface of the friction zone not exactly, but by a concentric to the central axis radial profiling is enlarged.  

Durch die Profilierung der Reibzone erhält die Reibscheibe eine größere wirksame Reibfläche.The friction disc is given a profile by the friction zone a larger effective friction surface.

Die spezifische Flächenpressung wird bei gegebener Anpreßkraft geringer.The specific surface pressure is given the contact pressure less.

Die größere wirksame Reibfläche führt die Wärme besser ab.The larger effective friction surface dissipates the heat better.

Bei einer bevorzugten Ausführungsform ist die Reibscheibe an der Oberfläche der Reibzone mit kreisringförmigen, zu der Mittelachse konzentrischen Nuten versehen.In a preferred embodiment, the friction disc on the surface of the friction zone with circular, to which Provide concentric grooves in the central axis.

Mit der Ausbildung der Nuten lassen sich gegenüber einer ebenen Reibscheibe verschiedene Kraftverhältnisse realisieren.With the formation of the grooves can be level Realize different friction ratios.

Bei einer Bremsscheibe für die Scheibenbremse eines Kraftfahr­ zeugs, die Nuten an der mit den Bremsbacken zusammenwirkenden Reibfläche hat, ergibt sich eine verbesserte Bremswirkung. Die Bremsbacken können von vornherein ein dem Nutmuster kom­ plementäres Oberflächenprofil haben. Nach den Feststellungen der Erfindung schleifen sich aber herkömmliche ebene Brems­ backen in kurzer Zeit so weit ein, daß ein vollflächiger Kon­ takt mit der genuteten Bremsscheibe gewährleistet ist. With a brake disc for the disc brake of a motor vehicle stuff, the grooves on the interacting with the brake shoes Has friction surface, there is an improved braking effect. The brake shoes can be a groove pattern from the start have a complementary surface profile. According to the findings However, the invention grind conventional flat brake bake in a short time so far that a full Kon is guaranteed with the grooved brake disc.  

Bei einer bevorzugten Ausführungsform ist das Profil der Nuten bogenförmig.In a preferred embodiment, the profile of the grooves arched.

Bei einer bevorzugten Ausführungsform ist das Profil der Nuten kreisbogenförmig. Die Nuten sind weniger als der Radius des Kreisbogens tief.In a preferred embodiment, the profile of the grooves circular arc. The grooves are less than the radius of the Circular arc deep.

Bei einer bevorzugten Ausführungsform sind die Nuten in gleichem radialen Abstand angeordnet.In a preferred embodiment, the grooves are in arranged the same radial distance.

Die erfindungsgemäße Reibscheibe hat eine bevorzugte Verwendung als Bremsscheibe insbesondere für die Scheibenbremse eines Kraftfahrzeugs oder als Kupplungsscheibe.The friction disk according to the invention has a preferred use as a brake disc in particular for the disc brake Motor vehicle or as a clutch disc.

Die Erfindung wird im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Gezeigt ist die halbseitige diametrale Schnittansicht der Bremsscheibe einer Scheibenbremse.The invention is based on one in the drawing illustrated embodiment explained in more detail. Shown is the half-sided diametrical sectional view of the brake disc a disc brake.

Die Bremsscheibe 10 hat im Wirkbereich der Bremsbacken kreis­ ringförmige, zu ihrer Achse konzentrische Nuten 12. Das Profil der Nuten 12 ist ein Kreisbogen mit einer Umfangserstreckung von ca. 150°. Die Nuten 12 sind in gleichem radialen Abstand angeordnet. Zwischen den Nuten 12 bleiben ebene Partien 14 der Reibzone stehen. The brake disc 10 has circular annular grooves 12 concentric with its axis in the effective area of the brake shoes. The profile of the grooves 12 is an arc with a circumferential extent of approximately 150 °. The grooves 12 are arranged at the same radial distance. Flat portions 14 of the friction zone remain between the grooves 12 .

Andere mögliche Oberflächenprofile der Bremsscheibe sind in den Radialschnitten 16, 18 und 20 dargestellt. Other possible surface profiles of the brake disc are shown in the radial sections 16 , 18 and 20 .
