In weiterer Ausbildung der Erfindung wird der Kühlmittelraum zwischen Anlauf- und Bremsring durch eine konzentische Rippe in zwei Ringkanäle derart aufgeteilt dass das Kühlmittel durch eine zwischen innerer Kühlmittel-Zuflussöffnung und äusserer Ausflussöffnung liegende Aussparung hindurch vom inneren in den äusseren Ringskanal überströmen kann, so dass das Kühlmittel den Anlaufring zweimal umströmt. In noch weiterer Ausbildung der Erfindung ist der zur Bremsung axial bewegt zweite Bremsring über elastische Leitungen mit den Zu- und Abführkanälen im Ständer verbunden.According to the invention, the two will conduct the cooling liquid Brake rings, whereby the one brake ring can be part of the stator, i1 essential designed in two parts in such a way that the brake contact surface is and outside diameter sealed stop ring is formed on its through Coolant-acted back surface has ribs that extend on the second Support formed as a ring cylinder housing part of the brake ring. In further Formation of the invention is the coolant space between the start-up and brake ring divided by a concentric rib into two ring channels in such a way that the coolant through one between the inner coolant inflow opening and the outer outflow opening Flow over the lying recess from the inner to the outer annular channel can so that the coolant flows around the thrust ring twice. In further training of the invention is the second brake ring moved axially for braking via elastic Lines connected to the feed and discharge channels in the stand.

Ferner wird erfindungsgemäss vorgeschlagen, die Bremse sowohl hydraulisch durch einen für sich bekannten hydraulischen Ringzylinder als auch mechanisch durch eine für sich bekannte Spreizbetätigung mittels Rollkörper auf Schrägbahnen zu betätigen.Furthermore, it is proposed according to the invention that the brake be both hydraulic by a hydraulic ring cylinder known per se as well as mechanically to operate a known spreading actuation by means of rolling bodies on inclined paths.

Der als der eine Bremsring ausgebildete Ständer 1 ist mittels Stiftschrauben 2 an den Fortsätzen 3 des Schaltgetriebes 4 befestigt und trägt über elastische Blechsegmente 5 den zweiten in Umfangsrichtung fest, axial jedoch beweglichen Bremsring 6, der zum Bremsen mittels des Druckringcs 7 zur Anlage gebracht wird. Der Druckring 7 ist in einem Ringzylinderraum 8 des Bremsdeckeis 9 untergebracht und durch eine Ringrnanschette 10 abgedichtet. Mit der Abtriebswelle 11 läuft die Bremslamelle 12 um, die beim Bremsen mit den Anlaufflächen der Anlauf'ringe 13 und 14 in Reibungsschluss gebracht werden. Der Anlaufring 13 ist abgedichtet im Ständer L und der Anlaufring 14 im Bremsring 6 gelagert. Jeder Anlaufring weist eine konzontrischo Rippe 131 bzw. 141 auf, mit der der Wasserraum zwischen Ständer und Anlaufring bzw. Bremsring und Antaufring in zwei Ringkanäle 15 und 16 bzw. 17 und 18 aufgeteilt wird, die an der Stelle der Zuführungsöffnung 19 und der Abführungsöffnung 20 eine Aussparung ? 23 aufweist, um ein Durchtreten des Külitmittels vom inneren Ringraum 16 bzw.It is one on the gearbox of a heavy commercial vehicle Flanged, water-cooled full-lined disc brake, clie over the cardan shaft acts on the axle drives of the vehicle. Fig. 1 gives the longitudinal section the brake and FIG. 2 shows a cross section through a brake ring again. That as that a brake ring formed stand 1 is by means of studs 2 on the extensions 3 of the gearbox 4 attached and carried over elastic sheet metal segments 5 the second in the circumferential direction fixed, but axially movable brake ring 6, the braking is brought to the plant by means of the pressure ring 7. The pressure ring 7 is in one Housed annular cylinder space 8 of the brake cover 9 and by an annular collar 10 sealed. With the output shaft 11, the brake plate 12 rotates, which when Brakes brought into frictional engagement with the contact surfaces of the Anlauf'ringe 13 and 14 will. The thrust ring 13 is sealed in the stator L and the thrust ring 14 in Brake ring 6 supported. Each stop ring has a concetrical rib 131 or 141 with which the water space between the stator and the thrust ring or the brake ring and the thrust ring is divided into two annular channels 15 and 16 or 17 and 18, which at the point of Feed opening 19 and the discharge opening 20 a recess? 23 has, in order for the coolant to pass through from the inner annular space 16 or
