Description
Reibscheibenkupplung oder -bremse Die Erfindung betrifft Reibscheibenkupplungen oder Reibscheibenbremsen mit durch je zwei Flächen gebildeten Reibpaarungen.
Zur Erhöhung des Reibwertes und zur Verbesse rung der Wärmeableitung je Einheit der projizierten Scheibenfläche wird nach vorliegender Erfindung vor geschlagen, den Reibteil je der einen Fläche der Reib paarungen in eine Anzahl Reibstellen aufzuteilen, an denen Linien- oder Punktberührung auftritt.
In einer bevorzugten Ausführungsform der Erfin dung wird die Reibfläche einer Reibscheibe wellen förmig gestaltet, beispielsweise mit radial verlaufen den Wellentälern versehen.
Es können insbesondere beide Seiten einer Reib scheibe mit radialen Wellen versehen sein. In der Kupplung bzw. Bremse sind dann abwechselnd ge wellte und glatte Scheiben nebeneinander angeordnet.
Die Wellungen auf beiden Seiten der Reibscheibe sind vorzugsweise derart angeordnet, dass die Reib scheibe überall annähernd gleiche Wandstärke besitzt.
Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar, und zwar zeigt: Fig. 1 eine gewellte Reibscheibe in Stirnansicht und Fig. 2 den Ausschnitt aus der gewellten Scheibe und zwei anliegenden glatten Scheiben, in Radial richtung gesehen.
1 stellt eine kreisringförmige Reibscheibe dar, die mit einer Keilverzahnung 2 versehen ist. In die Reibscheibe sind radial verlaufende Wellentäler 3 eingearbeitet, welche je zu beiden Seiten eines Wellen berges 4 liegen.
Fig. 2 zeigt in Radialansicht je einen Ausschnitt aus einer gewellten Scheibe 1 mit zwei anliegenden glatten Scheiben 5 und 6. Die Wellung 3, 4 ist gleich laufend oder annähernd gleichlaufend mit der Wellung 3', 4' auf der entgegengesetzten Seite der Scheibe 1. Die an den linienförmigen Berührungsstellen der Wellenberge 4, 4' der gewellten Scheibe entwickelte Wärme verteilt sich auf die ganze Scheibe und wird an die umgebende Luft oder an das in den radialen Tälern befindliche öl abgegeben.
Die vorhandene Linienberührung zwischen der gewellten und der ebenen Reibfläche begünstigt die Späneabfuhr. Die gewellte Scheibenfläche verhindert das Kleben der Scheiben nach Ausschalten der Kupp lung.
Die einzelnen Wellen können statt geradlinig radial auch bogenförmig verlaufen.
Friction disk clutch or brake The invention relates to friction disk clutches or friction disk brakes with friction pairings each formed by two surfaces.
To increase the coefficient of friction and improve the heat dissipation per unit of the projected disc surface, the present invention proposes to divide the friction part depending on the one surface of the friction pairings into a number of friction points where line or point contact occurs.
In a preferred embodiment of the inven tion, the friction surface of a friction disk is designed to be wave-shaped, for example provided with the wave troughs extending radially.
In particular, both sides of a friction disc can be provided with radial waves. In the clutch or brake, alternately corrugated and smooth disks are arranged side by side.
The corrugations on both sides of the friction disc are preferably arranged such that the friction disc has approximately the same wall thickness everywhere.
The drawing shows an embodiment of the invention, namely: Fig. 1 shows a corrugated friction disc in an end view and Fig. 2 shows the detail of the corrugated disc and two adjacent smooth discs, seen in the radial direction.
1 shows an annular friction disk which is provided with a spline 2. Radially extending wave troughs 3 are incorporated into the friction disk, each lying on both sides of a wave mountain 4.
2 shows a radial view of a section of a corrugated disk 1 with two adjacent smooth disks 5 and 6. The corrugation 3, 4 is the same or approximately the same as the corrugation 3 ', 4' on the opposite side of the disk 1. The heat developed at the line-shaped contact points of the wave crests 4, 4 'of the corrugated disk is distributed over the entire disk and is given off to the surrounding air or to the oil in the radial valleys.
The existing line contact between the corrugated and the flat friction surface promotes chip evacuation. The corrugated disc surface prevents the discs from sticking after the clutch is switched off.
The individual waves can also run in an arc instead of a straight line.
