Abstract

The vehicle's coupling-disc has four cruciform lining-discs (9, 10) equidistant from the coupling-hub's (3) central axis. Each pair of sintered discs is diametrically opposite each other on the outer rim (8) of two adjacent elongated discs (1, 2) fixed to the coupling-hub. The lining-discs are riveted (4) together and to the coupling-hub. The discs' rim has two diametrically opposite smaller circle-arcs (6), adjacent straight parts (7), and two larger diametrically opposite circle arcs (8). The lining discs vary in thickness to compensate for axial displacement; the frictional end surfaces of all lining discs are on one plane. The coupling-hub is riveted on one side to a support-plate (5) and to the join between the two discs on the other side. ADVANTAGE - Each disc is free to expand radially when the temperature increases so that their ends do not corrugate.

Description

Die Erfindung betrifft eine Kupplungsscheibe für ein Kraftfahrzeug, mit vier kreuzförmig, äquidistant zur Mittenachse der Kupplungsscheibe angeordneten Belagscheiben.The invention relates to a clutch disc for a motor vehicle, with four arranged in a cross shape, equidistant from the center axis of the clutch disc Washers.

Eine solche Kupplungsscheibe ist in US-PS 32 80 949 beschrieben. Die vier Belagscheiben aus Keramik sind in Ausnehmungen eines kreuzförmigen Scheibenkörpers befestigt. Um mit der Kupplungsscheibe Drehschwingungen zu dämpfen, enthält ihre Habe eine Dämpfungsvorrichtung, die eine begrenzte Relativdrehung in der Kupplungsscheibe zuläßt. Bei hoher Momentdurchleitung in der daraus resultierenden starken Erwärmung besteht die Gefahr, daß sich der einstückige Scheibenkörper verwirft. Es ist die Aufgabe der Erfindung deine Kupplungsscheibe zu entwickeln, bei der temperaturbedingte Wellungen an den Stirnflächen der Kupplungsscheiben vermieden werden.Such a clutch disc is described in US-PS 32 80 949. The four Ceramic topping disks are recessed in a cross shape Disk body attached. To prevent torsional vibrations with the clutch disc dampen, their belongings include a damping device that is limited Permits relative rotation in the clutch disc. With high torque transmission in the resulting strong warming there is a risk that the one-piece disc body warps. It is the object of the invention to develop your clutch disc with temperature-related undulations the front surfaces of the clutch discs can be avoided.

Eine Lösung dieser Aufgabe gelingt mit den kennzeichnenden Merkmalen des Anspruchs 1. Da die Kupplungsscheibe aus zwei kreuzförmig zueinander liegenden, länglichen Scheibenkörpern zusammengesetzt ist, kann sich jeder Scheibenkörper bei Temperaturerhöhung frei radial dehnen. Es wird verhindert, daß die Kupplungsscheiben sich an ihren Stirnseiten wellen und die Belagscheiben einseitig an den Gegenflächen anliegen.This problem can be solved with the characteristic features of Claim 1. Since the clutch disc consists of two cross-shaped to each other lying, elongated disc bodies is composed, everyone can When the temperature rises, freely stretch the disc body radially. It will prevents the clutch discs from curling on their faces and the washers rest on one side on the counter surfaces.

Wenn die Scheibenkörper gemäß Anspruch 2 durch Stahlnieten miteinander und mit der Kupplungsnabe verbunden sind, können sich bei Einleitung von Drehschwingungen die Scheibenkörper geringfügig gegenüber der Kupplungsnabe elastisch verdrehen und tragen so zur Schwingungsdämpfung bei, ohne daß eine zusätzliche Dämpfungsvorrichtung erforderlich wäre.If the disc body according to claim 2 by steel rivets with each other and are connected to the clutch hub, when Torsional vibrations the disc body slightly compared to the clutch hub twist elastically and thus contribute to vibration damping without a additional damping device would be required.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend erläutert. An embodiment of the invention is shown in the drawing and is explained below.

Eine Kupplungsscheibe ist aus zwei rechtwinklig zueinander stehenden, länglichen Scheibenkörpern 1 und 2 zusammengesetzt. Die Scheibenkörper sind miteinander und mit der Kupplungsnabe 3 durch zwölf Stahl-Nieten 4 verbunden. An der einen Seite ist der Scheibenverband mit der Kupplungsnabe 3, an der anderen Seite zur Versteifung mit einem Stützblech 5 vernietet. Die beiden Scheibenkörper 1, 2 sind aus gleichem Stahlwerkstoff hergestellt, gleich gestaltet und dimensioniert. Bei Temperaturerhöhung tritt deshalb eine gleichmäßige radiale Ausdehnung ein; Verwerfungen und Scheibenwellungen werden vermieden.A clutch disc is composed of two elongated disc bodies 1 and 2 which are at right angles to one another. The disc bodies are connected to one another and to the coupling hub 3 by twelve steel rivets 4 . The disc assembly is riveted to the coupling hub 3 on one side and to a reinforcing plate 5 on the other side for reinforcement. The two disk bodies 1 , 2 are made of the same steel material, designed and dimensioned the same. When the temperature rises, there is therefore a uniform radial expansion; Warpage and disc corrugations are avoided.

Die Berandung der Scheibenkörper 1, 2 besteht aus zwei diametral gegenüberliegende Kreisbögen 6 mit kleinerem Radius, sich daran anschließenden tangentialen Geraden 7 und zwei diametral gegenüberliegenden Kreisbögen 8 mit größerem Radius.The edges of the disk bodies 1 , 2 consist of two diametrically opposite circular arcs 6 with a smaller radius, adjoining tangential straight lines 7 and two diametrically opposite circular arcs 8 with a larger radius.

In diese Kontur sind am Außenrand der Längserstreckung an dem Scheibenkörper 1 zwei Belagscheiben 9, an dem anderen Scheibenkörper 2 zwei Belagscheiben 10 angeklebt. Sie sind so geformt, daß sie in die Kontur der Scheibenkörper 1, 2 integriert sind. Die Belagscheiben 9, 10 bestehen aus Sintermaterial. Die Belagscheiben 9 um die Scheibenstärke s der Scheibenkörper 1, 2 dicker als die Belagscheiben 10, um den Axialversatz auszugleichen und alle Reibflächen der Belagscheiben 9, 10 in eine Ebene zu verlegen.In this contour, two facing disks 9 are glued to the disk body 1 on the outer edge of the longitudinal extent, and two facing disks 10 are glued to the other disk body 2 . They are shaped so that they are integrated into the contour of the disc body 1 , 2 . The covering disks 9 , 10 consist of sintered material. The lining disks 9 by the disk thickness s of the disk bodies 1 , 2 are thicker than the lining disks 10 in order to compensate for the axial offset and to lay all friction surfaces of the lining disks 9 , 10 in one plane.
