Description

■ Die den Gegenstand der vorliegenden Erfindung bildenden Verbesserungen der im Hauptpatent geschützten Reiblamellenanordnung bestehen im wesentlichen darin, daß die in axialer Richtung nachgiebigen, in der Umfangsrichtung praktisch starren Zwischenglieder zwischen benachbarten Reiblarnellen bzw. zwischen den Endlamellen und ihrem Träger nicht als durchgehende Ringscheiben, sondern als Ringscheibensektoren ausgebildet sind. Dadurch wird unter voller Wahrung der Vorteile der Bauart des Hauptpatents bei geringeren Gestehungskosten die Verbindung der Lamellen untereinander sowie gegebenenfalls mit ihrem Träger bei völlig ausreichender Starrheit in der Umfangsrichtung in axialer Richtung besonders elastisch. ^v ■ The object of the present invention forming improvements of the friction disc arrangement protected in the main patent consist essentially in the fact that the axially flexible, in the circumferential direction practically rigid intermediate members between adjacent friction discs or between the end discs and their carrier not as continuous ring disks, but as Annular washer sectors are formed. As a result, while fully preserving the advantages of the design of the main patent at lower production costs, the connection of the lamellas with one another and, if necessary, with their carrier is particularly elastic in the axial direction with completely sufficient rigidity in the circumferential direction. ^v

In der Zeichnung, die eine Gruppe von gemäß der Erfindung miteinander verbundenen Reiblamellen beispielsweise veranschaulicht, stelltIn the drawing, a group of interconnected according to the invention For example, friction disks illustrates provides

Abb. 2 einen Schnitt nach der Linie A-B der Abb. ι zeigt,Fig. 2 shows a section along the line AB in Fig. Ι,

In Abb. ι sind vier Reiblamellen 1, i^a, i^b und i^c .dargestellt, und zwar in Form durchgehender Ringscheiben aus Stahlblech, Grauguß ο. dgl. Je zwei benachbarte Lamellen sind durch je sechs Ringscheibensektoren aus federndem Blech miteinander verbunden, und zwar sind, abgesehen von den Endlamellen., auf den beiden Seiten jeder Lamelle je drei solcher Ringsektoren 2, 3, 4 bzw. 5, 6, 7 vorgesehen. Die Anordnung im einzelnen ergibt sich aus Abb. 2. Diese läßt erkennen, daß die eine Gruppe von Ringsektoren 2, 3, 4 mit Abständen, die etwa gleich ihrer Umfangsausdehnung sind, gleichmäßig über die betreffende Lamelle i^a verteilt angeordnet sind und daß die auf der anderen Seite der Lamelle vorgesehenen Ringsektoren 5, 6, 7 gegen-In Fig. Ι four friction disks 1, i ^a , i ^b and i ^c. Shown, in the form of continuous annular disks made of sheet steel, gray cast iron ο. Like. Two adjacent slats are connected to each other by six annular disk sectors made of resilient sheet metal, namely, apart from the end slats., On the two sides of each slat three such annular sectors 2, 3, 4 or 5, 6, 7 are provided . The detailed arrangement is shown in Fig. 2. This shows that the one group of ring sectors 2, 3, 4 with distances that are approximately equal to their circumferential extent, are evenly distributed over the relevant lamella i ^a and that the on the other side of the lamella provided ring sectors 5, 6, 7 opposite

Claims

are offset above the former. The ring sectors are conveniently connected to the lamellae and among themselves by means of spot welding. The connection of two adjacent ring sectors 2,2 ^a etc-i or Sj S " etc. (Fig. 1) takes place with the help of .v |>p; Associated sectors are welded.

As in the case of the main patent, the two outer lamellae 1 and i ^c or even just one of them can also be connected to the associated lamella carrier or driver by means of individual ring sectors.

1;; But you can also use one of the end lamellas let the driver engage directly in the usual manner.

In the case shown, it is assumed that

it is a group of inner disks, d. H. those with an internal Cooperate carrier or carrier. The invention is natural though also applicable to lamellae that interact with an external driver. In Fig. Ι are of the ring sectors of simplicity only those that appear in the section are shown.

The innovation is of course not limited to training or use the friction plates in clutches; Rather, it can also be used with friction plates for brakes to be used with advantage. Instead of welding the ring sectors with the Lamellae and with one another, of course, in other ways, e.g. B. connected by rivets will.

■ '7; Patent claims:

J * .._- i. Multi-disc clutch, in particular for ■■ '■■■ motor vehicles, according to patent 682187, characterized in that the intermediate members, which are flexible in the axial direction and practically rigid in the circumferential direction, are designed as annular disk sectors between adjacent friction plates of the clutch or between the end plates and their carrier.

2. Multi-disc clutch according to claim 1, characterized in that "each two adjacent Lamellae by interconnected in pairs, at a distance Sheet metal pieces distributed over the circumference are connected to one another, the spring sheet metal pieces belonging to a pair of lamellae are offset from those belonging to the adjacent pair of lamellas.

3. Multi-disc clutch according to claim 1 and 2, characterized in that the ring sector-shaped connecting pieces on their free peripheral edges by intermediation of sheet metal folds (8) with one another, preferably in a manner known per se by means of spot welding are connected.
