Description

Durch das Hauptpatent DBP....... (Az. P 16 BO 130.2) ist eine Getriebe-Scheibenbremse für Dauerbetrieb unter Schutz gestellt, bei der die flüssigkeitsgekühlten, in Umfangsrichtung feststehenden Gehäuseteile einseitig als Bremsflächen ausgebildet sind und die mit Sintermetall- oder Sinterkeramik-Reibbelägen ausgestatteten Bremsscheiben von den Bremsgehäuseteilen umschlossen werden.The main patent DBP ....... (Az. P 16 BO 130.2) is a geared disc brake for continuous operation under protection, in which the liquid-cooled, fixed in the circumferential direction of the housing parts are designed on one side as braking surfaces and with sintered metal or Brake disks equipped with sintered ceramic friction linings are enclosed by the brake housing parts.

Die Betätigung der Scheibenbremse erfolgt durch einen relativ zu den Bremsscheiben schwenkbar gelagerten Detätigungsring, der beidseitig mit in Umfangsrichtung ansteigenden Vorsprüngen ausgestattet ist und über Rollen, die sich auf ebenfalls in Umfangsrichtung ansteigenden Vorsprüngen auf den Innenflächen der Bremsscheiben abstützen, die Bremsscheiben zum Bremsen an den. feststehenden Gehäuseflächen dadurch anlegen, daß der Betätigungsring für sich durch eine Betätigungsbremse abgebremst wird.The disc brake is actuated by an actuation ring which is pivotably mounted relative to the brake discs and which is equipped on both sides with projections that rise in the circumferential direction and by means of rollers that are supported on the inner surfaces of the brake discs on the inner surfaces of the projections that also rise in the circumferential direction, the brake discs for braking. create fixed housing surfaces in that the actuating ring is braked by an actuating brake.

Die vorliegende Erfindung bezieht sich auf derartige Scheibenbremsen und hat sich zur Aufgabe gesetzt, die Bremsen dadurch zu-verbessern, daß auch die zum Abbremsen des Betätigungsringes angeordneten Segmentbremsen an den Kühlkreislauf angeschlossen werden.The present invention relates to such disc brakes and has set itself the task of improving the brakes by also having the to brake the actuating ring arranged segment brakes on the cooling circuit be connected.

Die erfindungsgemäße Lösung der Aufgabe besteht darin, daß die mit hohlem Belagträger ausgerüstete Betätigungsbremse zwischen den Gehäusehälften derart angeordnet ist, daß der mit Kühlflüssigkeit gefüllte Hohlraum des Belagträgers ganz oder zum Teil den Kühlmittelkreislauf zwischen den beiden Gehäusehälften schließt.The solution to the problem according to the invention is that the actuating brake equipped with a hollow lining carrier is arranged between the housing halves in such a way that the coolant-filled cavity of the lining carrier completely or partially closes the coolant circuit between the two housing halves.

In weiterer Ausbildung der Erfindung ist die Betätigungsbremse als Hebelbremse ausgebildet und der die Sremsbelagsegmente tragende hohle Bremshebel an zylindrischen Fort-Sätzen in Bohrungen der Gehäusehälften schwenkbar aufgehängt, wobei das Kühlmittel über diese Fortsätze in den hohlen Bremshebel geführt wird.In a further embodiment of the invention, the actuating brake is as Lever brake is formed and the hollow brake lever carrying the brake lining segments suspended from cylindrical extensions in bores in the housing halves so that they can pivot, whereby the coolant is guided into the hollow brake lever via these extensions.

In den Abbildungen ist ein Ausführungebeispiel der Erfindung dargestellt. In Fig. 1 ist ein Längsschnitt der oberen Hälfte einer Getriebescheibenbremse veranschaulicht. Fig. 2 gibt einen in Fig. 1 mit A-B gekennzeichneten Querschnitt wieder. In Fig. 3 ist eine in Fig. 2 mit E-F gekennzeichneter Schnitt durch den Betätigungshebel-wiedergegeben.An exemplary embodiment of the invention is shown in the figures. In Fig. 1, a longitudinal section of the upper half of a gear disc brake is illustrated. FIG. 2 shows a cross section marked A-B in FIG. 1. In Fig. 3 shows a section through the actuating lever, identified by E-F in FIG. 2.

In den Abbildungen ist mit 1 das Schaltgetriebe bezeichnet, mit dessen Hauptwelle 2 die beiden mit Reibbelag 3 und 4 ausgestatteten Bremsscheiben 5 und 6 axial frei beweglich um= laufen. Das aus zwei Hälften 7 uQd 8 bestehende, aus Leichtmetall hergestellte Bremsgehäuse ist am Gehäuse des Schaltgetriebes 1 angeflanscht. Eine Wellendichtung 9 verhindert, daß Ö1 aus dem Getrieberaum in den sonst noch außen abgeschlossenen Bremsraum 10 eindringt. Durch Schnurringe 11, 12, 13,14 abgedichtet sind die aus Grau-, Temper- oder Stahlguß hergestellten Bremsringe 15 und 16 in den Leichtmetallgehäusen 7 und 8 in Umfangsrichtung fest gelagert. Jede Seite des Brems-gehäuses 7 und 8 ist mit einem spiraligen Kühlraum 17 biw.In the figures, 1 designates the gearbox, with the main shaft 2 of which the two brake disks 5 and 6 equipped with friction linings 3 and 4 rotate freely axially. The brake housing, which consists of two halves 7 and 8 and is made of light metal, is flanged to the housing of the gearbox 1. A shaft seal 9 prevents oil from penetrating from the gear chamber into the brake chamber 10, which is otherwise closed on the outside. Sealed by cord rings 11, 12, 13, 14, the brake rings 15 and 16 made of gray, malleable or cast steel are fixedly mounted in the circumferential direction in the light metal housings 7 and 8. Each side of the brake housing 7 and 8 is provided with a spiral cooling space 17 biw.

18 ausgestattet, Die Kühlmittelüberleitung von einer Bremsgehäuseh$lfte auf die andere erfolgt durch Dohrungen 19 und 20, die zur Aufnahme der zylindrischen Fortsätze 21 und 22 des hohl gegossenen, die Belagsegmente 23 und 24 tragenden Bremshebels 25 erweitert sind.18 equipped, the coolant transfer from one brake housing half to the other takes place through holes 19 and 20, which are expanded to accommodate the cylindrical extensions 21 and 22 of the hollow cast brake lever 25 supporting the lining segments 23 and 24.

Die Abdichtung der Fortsätze 21 und 22 erfolgt durch Schnurringe 26 und 27, Der Hohlraum des Bremshebels ist zweckmäßigerweiee so ausgebildet, daß der ganze Dremehebel vom Kühlmittel durchströmt werden muß. Hierzu ist im vorliegenden ,Beispiel eine Rippe 28 angeordnet.The extensions 21 and 22 are sealed by cord rings 26 and 27, The cavity of the brake lever is expediently designed so that the coolant must flow through entire Dreme levers. For this purpose is in the present , Example of a rib 28 arranged.

Die Bremse wird durch eine Membran 29 durch Druckluft betätigt. Die Membran wirkt über einen Stößel 30 direkt auf den Brems= hebel 25. Eine Rückzugsfeder 31 hält den Bremshebel in der Ausgangslage, die durch eine NAchstellschraube 32 eingehalten wird. Bei einer Betätigung des Bremshebels 25 durch die Membran 29 erzeugen die Reibbeläge 23 und 24 ein Bremsmoment,. das den Betätigungsring 33 relativ gegenüber den Bremsscheiben 5 und 6 zurückhält. OPdurch Werden über die gleichmäßig am Umfang verteilten Rollen 34 und 35 über am Betätigungsring 33 und auf den Innenflächen der ßremascheiben 5 und 6 angeordnete, in Umfangsrichtung ansteigende Vorsprünge die Bremsscheiben 5 und 6 auseinendergepreßt und drücken die Reibbeläge 3 und 4 gegen die feststehenden Bremsringe 15 und 16.The brake is actuated by compressed air through a membrane 29. The membrane acts directly on the brake lever 25 via a plunger 30. A return spring 31 holds the brake lever in the starting position, which is maintained by an adjusting screw 32. When the brake lever 25 is actuated by the membrane 29, the friction linings 23 and 24 generate a braking torque. which retains the actuating ring 33 relative to the brake disks 5 and 6. OPdurch are about equally spaced rollers 34 and 35 via the actuating ring 33 and on the inner surfaces of ßremascheiben 5 and 6 arranged rising in the circumferential direction of the projections, the discs 5 and 6 auseinendergepreßt and press the friction linings 3 and 4 against the fixed brake rings 15 and 16.
