Abstract

Brake disc consists of two parts, a friction ring (1) and brake disc holder (2) or of several parts, with additional intermediate ring (3), and also one possibly with slits (5) at an angle of 0[deg] to 90[deg] made of the same or different materials joined together using lengthwise or cross compression connections. One or more of the joined surfaces are covered wholly or partly with hard particles (4) bedded into a matrix of nickel, adhesive or other material forming a special coating or otherwise held on the joint or its surface. They produce a microform connection to frictionally connect the compression connections. All or part of the joint surface or partner is coated.

Description

Einige Fahrzeughersteller verwenden in Oberklassemodellen oder Sportfahrzeugen mehrteilige Bremsscheiben, die aus einem Reibring, einem Bremsscheibentopf und zugehörigen Verbindungselementen aufgebaut sind. Wesentlicher Vorteil ist die Reduzierung der ungefederten und rotierenden Massen am Radträger. Dabei besteht der Reibring aus einem Werkstoff wie bei einer einteiligen Standardbremsscheibe (z.B. GG-15). Für den thermisch nicht so hoch beanspruchten Bremsscheibentopf wird ein leichterer Werkstoff (Werkstoffleichtbau) oder ein Werkstoff gewählt, der in der Konstruktion beanspruchungsgerecht dimensioniert wird (Strukturleichtbau). Die Verbindung von Topf und Reibring erfolgt durch Formschluss mittels mehrerer Elemente. Bekannt sind Ausführungen von Verbundbremsscheiben, die mittels Klammern und Schrauben, eingegossenen Stahlstiften oder Nieten (Vgl. DE 102 53 451 A1 ) gefügt sind. Diese Bremsscheiben sind zwar in ihrer Masse reduziert; ihnen stehen Nachteile durch die größere Teilezahl und aufwendigere Fügeverfahren gegenüber, die letztendlich höhere Produktionskosten bedingen. Andere Lösungen sind Verzahnungen oder Keilwellenprofile zur Momentübertragung, die aber ebenfalls Mehraufwand in der Herstellung bewirken.Some vehicle manufacturers use multi-piece brake discs in top-of-the-range models or sports vehicles, which are made up of a friction ring, a brake disc hub and associated fasteners. The main advantage is the reduction of unsprung and rotating masses on the wheel carrier. The friction ring consists of a material similar to a one-piece standard brake disc (eg GG-15). For the brake disc pot, which is not subject to high thermal loads, a lighter material (material lightweight construction) or a material is selected which is dimensioned to suit the structure in terms of stress (structural lightweight construction). The connection of pot and friction ring is done by positive locking by means of several elements. Embodiments of composite brake disks known by means of clamps and screws, cast-in steel pins or rivets (cf. DE 102 53 451 A1 ) are joined. Although these discs are reduced in mass; they are faced with disadvantages due to the larger number of parts and more complex joining methods, which ultimately result in higher production costs. Other solutions are gears or splines for torque transmission, but also cause additional expense in the production.

Problemproblem

Leistungsstärkere und schwere Kraftfahrzeuge benötigen eine größer dimensionierte Bremsanlage. Damit wird in der Regel der Durchmesser einer Bremsscheibe größer und die Wandstärken des Bremsscheibentopfes werden aus gusstechnischen Gründen stärker dimensioniert. Neben der damit hinreichend bekannten Problematik der Zunahme der ungefederten und rotatorischen Massen am Radträger sind solche Bremsscheiben anfälliger in Bezug auf geometrische Abweichungen wie Dickenschwankungen, Axialversatz und Schirmung unter thermischer Beanspruchung. Ferner stellen sich erhöhte, teilweise nur mit großem Aufwand realisierbare Anforderungen an den Gießprozess. Vorteile bieten hier so genannte Verbundbremsscheiben, bei denen eine Funktionstrennung zwischen Reibring und Flansch zur Anbindung an die Radnabe erfolgt.More powerful and need heavy vehicles a larger sized Brake system. This is usually the diameter of a brake disc bigger and the wall thicknesses of the brake disk hub are dimensioned stronger for technical reasons. In addition to the well-known problem of increasing the unsprung and rotatory masses on the wheel are such discs vulnerable with respect to geometric deviations such as thickness variations, axial misalignment and shielding under thermal stress. Further arise increased, partially only with big Effort feasible requirements of the casting process. There are advantages here Composite brake discs, in which a functional separation between friction ring and flange for connection to the wheel hub takes place.

Lösungsolution

Ziel dieser Erfindung ist es, eine im Gewicht reduzierte Bremsscheibe als Verbundbremsscheibe mit erhöhter Drehmomentübertragungsfähigkeit auszuführen, bei der auf zusätzliche Verbindungselemente wie Schrauben, Nieten oder Stahlstifte zwischen Reibring und Bremsscheibeninnenteil wie bei bestehenden Konstruktionen verzichtet werden kann. Das wird dadurch erreicht, dass Bremsscheibentopf und Reibring über eine Preßverbindung mit eingelagerten harten Partikeln, die auch auf einen zusätzlichen Zwischenring aufgebracht sein können, ohne zusätzliche Sicherungselemente verbunden werden.aim This invention is a reduced in weight brake disc as a composite brake disc with increased Torque capacity perform, at the extra on Connecting elements such as screws, rivets or steel pins between Friction ring and disc interior as in existing designs can be waived. This is achieved by the fact that brake disc pot and friction ring over a press connection with embedded hard particles, which also on an additional Intermediate ring can be applied without additional Fuse elements are connected.

Erreichte Vorteilereached advantages

Neben der Gewichtsoptimierung bei Werkstoff- und/oder Strukturleichtbau ergeben sich weitere Vorteile in der vorgenannten Konstruktion durch eine einwandfreie Zentrierung gegenüber anderen Verbundbremsscheiben. Eine hohe Rundlaufgenauigkeit wird ermöglicht. Die mehrteilige Ausführung ermöglicht bessere Gestaltungsmöglichkeit hinsichtlich geometrischer Abweichungen im Hochtemperaturbereich (Schirmung und gleichmäßige Gefügeausprägung zur Vermeidung und/oder Verminderung lokaler Hitzeflecken). Ferner sind Pressverbindungen als schwingungsdämpfend bekannt, was den Komfortanspruch einer Bremsanlage sowohl im tieffrequenten Bereich (Bremsenrubbeln) als auch im akustischen Spektrum verbessern kann.Next the weight optimization in material and / or structural lightweight construction There are further advantages in the aforementioned construction by a perfect centering opposite other composite brake discs. A high concentricity is allows. The multipart design allows better design options with regard to geometric deviations in the high-temperature range (Shielding and uniform microstructure of the Avoidance and / or reduction of local heat spots). Further are Press connections known as vibration damping, what the comfort claim a brake system both in the low-frequency range (Bremsenrubbeln) as well as in the acoustic spectrum can improve.

Die mitunter zeit- und kostenintensive Nachbearbeitung wie bei einer konventionellen Bremsscheibe kann durch einfachere Handhabung der Einzelteile ausgeglichen werden. Durch den Verzicht auf zusätzliche Verbindungselemente ergeben sich zudem Vorteile beim Recycling.The sometimes time- and cost-intensive post-processing like a Conventional brake disc can be easier to handle Items are compensated. By doing without additional Connecting elements also offer advantages in recycling.

Weitere Ausgestaltung der ErfindungFurther embodiment the invention

Ziel der mehrteiligen Bremsscheibe ist es, auf zusätzliche Verbindungselemente zu verzichten, da sich so ein konsequenter Leichtbau realisieren lässt. Die Kombination von Reibring (1), der aus konventionellem Gusswerkstoff wie z.B. GG-15 hergestellt sein kann, und dem Bremsscheibentopf (2) (z.B. ein Aluminium-Werkstoff) erfolgt durch einen zylindrischen Pressverband als Längs- oder Querpressverbindung. Zur Erhöhung der Drehmomentübertragungsfähigkeit wird in der Pressfuge ein Zusatzwerkstoff aufgebracht, der aus Hartstoffpartikeln (z.B. Diamant) besteht. Konstruktionsbedingt entsteht somit eine Kombination aus form- und kraftschlüssiger Verbindung. Die Hartstoffbeschichtung kann entweder auf der Fügeseite des Reibrings oder Fügefläche des Bremsscheibentopfes erfolgen. Alternativ wird ein hartstoffbeschichteter (4) Zwischenring (3) vorgeschlagen, der zwischen den beiden Fügepartnern liegt. Der Zwischenring kann zur Vermeidung eines doppelten Pressverbandes unterbrochen sein. Vorzugsweise ist er als unter einem Winkel von 45° (5) geschlitzter Ring ausgeführt. Diese Konstruktion bewirkt Vorteile in der Herstellung, da ein in der Form und Gestaltung einfacheres und leichteres Bauteil als Bremsscheibentopf oder Reibring beschichtet werden muss.The aim of the multi-part brake disc is to dispense with additional fasteners, as this can be a consistent lightweight construction. The combination of friction ring ( 1 ), which may be made of conventional casting material such as GG-15, and the brake disk pot ( 2 ) (eg an aluminum material) is made by a cylindrical interference fit as a longitudinal or transverse press connection. To increase the torque transmission capability, an additional material is applied in the press joint, which consists of hard particles (eg diamond). Due to the design thus creates a combination of positive and non-positive connection. The hard material coating can take place either on the joining side of the friction ring or joining surface of the brake disk hub. Alternatively, a hard-coated ( 4 ) Intermediate ring ( 3 ) proposed, which lies between the two joining partners. The intermediate ring can be interrupted to avoid a double interference fit. Preferably, it is considered to be at an angle of 45 ° ( 5 ) slotted ring executed. This construction be has advantages in the production, since a simpler and lighter in shape and design component must be coated as a brake disc pot or friction ring.
