Description

Es sind Lamellen-Vollbelagscheibenbremsen bekannt, bei denen zwischen in Umfangsrichtung feststehenden Gehäuseteilen mit Reibbelag ausgerüstete Lamellen umlaufen. Es ist auch vorgeschlagen worden, die feststehenden Teile mit Fldssigkeitskühlung auszurüsten. Nachteilig bei derartigen Bremsen ist bisher die Unzugänglichkeit zu den Verschleissteilen. Bei einem Belagwechsel muss die Bremse geöffnet werden, was besonders bei flüssigkeitsgekühlten Bremsen wegen des Leerens der Flüssigkeitsräume schwierig ist, Die Erfindung hat sich zur Aufgabe gesetzt, diesen Mangel zu beseitigen. Erfindungsgemäss wird das ortsfeste Bremsgehäuse am Aussenumfang mit einem abnehmbaren Deckel ausgerüstet und der zur Aufnahme der Bremsiamelle dienende, mit den abzubremsenden Fahrzeugteilen verbundene, umlaufende Kupplungsflansch derart axial, verschiebbar angeordnet, dass nach Oeffnen des Deckels am Aussenumfang des Bremsgehäuses und nach Verschieben des Kupplungsflansches die Lamelle zwischen den Reibflächen entfernt und gewechselt werden kann.There are multi-disc full-lined disc brakes known in which between Housing parts fixed in the circumferential direction with lamellae equipped with friction lining circulate. It has also been proposed to use liquid cooling for the fixed parts equip. A disadvantage of such brakes is the inaccessibility the wearing parts. When changing the lining, the brake has to be released, what especially with liquid-cooled brakes because of the emptying of the liquid spaces is difficult, the invention has set itself the task of eliminating this deficiency. According to the invention, the stationary brake housing is provided with a removable one on the outer circumference Equipped cover and the one used to hold the brake disc with the ones to be braked Vehicle parts connected, circumferential coupling flange so axially displaceable arranged that after opening the cover on the outer circumference of the brake housing and After moving the coupling flange, the lamella is removed between the friction surfaces and can be changed.

In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt. Als Beispiel wurde die flüssigkeitsgekühlte Getriebebremse eines Omnibusses gewählt, welche am Schaltgetriebe angeordnet ist.In the drawings, an embodiment of the invention is shown. The liquid-cooled transmission brake of a bus was chosen as an example, which is arranged on the gearbox.

In Fig. 1 ist ein Längsschnitt, in Fig. 2 ein Querschnitt und in Fig. 3 eine Draufsicht dargestellt. Nit 1 ist die Abtriebswelle des Schaltgetriebes, mit 2 der über Schrauben 3 mit der nicht mit dargestellten Kardanwelle verbundene Kupplungsflansch gekennzeichnet. Das zweiteilige, aus Leichtmetall ausgeführte Bremsgehäuse 4, 5 ist an dem Trägerarm 6, der Bestandteil des Schaltgetriebes ist mit Schrauben 7 befertigt. Der in Umfangsrlchtung fest, axial dagegen bewegliche Bremsring 8 kann sowohl mechanisch durch eine Spreizvorrichtung 9, die sich am Gehäuseteil 5 abstützt, wie durch einen Hydraulikring 10, der in einem Zylinderringraum 11 des Gehäuseteiles 5 gelagert ist, zur Betätigung axial verschoben werden. Dle ßremsflächen werden durch Gusseisen- oder aus einer Kupferlegierung hergestellte Drckringe 12" und" 13 gebildet. Zwischen den Druckringon 12 und 13 läuft die mit Bremsbelag ausgerüstete Lamelle 14 um, die auf einer Verzahnung 15 des Abtriebsflansches 2 axial beweglich gelagert ist.In Fig. 1 is a longitudinal section, in Fig. 2 is a cross section and in Fig. 3 shows a plan view. Nit 1 is the output shaft of the gearbox, with 2 connected by screws 3 with the cardan shaft, not shown Coupling flange marked. The two-part brake housing made of light metal 4, 5 is on the support arm 6, which is part of the gearbox with screws 7 made. The brake ring 8 fixed in the circumferential direction but axially movable on the other hand can both mechanically by a spreader 9, located on the housing part 5 is supported, as by a hydraulic ring 10, which is in a cylinder ring chamber 11 of the Housing part 5 is mounted to be axially displaced for actuation. The braking surfaces are made of cast iron or copper alloy pressure rings 12 " and "13. Between the pressure rings 12 and 13 runs the one equipped with a brake lining Lamella 14 around which is axially movable on a toothing 15 of the output flange 2 is stored.

Zwischen Druckringon 12 und 13 und dem Gehäuseteil 4 bzw.Between the pressure ring 12 and 13 and the housing part 4 or

dem Bremsring 8 sind Hohlräume 16 und 17 angeordnet, in denen die Kühlflüssigkeit untergebracht ist. Zur mechanischen Be-"-tätigung der Bremse wirkt auf die Spreizvorrichtung 9 über ein Gastänge 18 ein Federspeicherzylinder 19 ein, der durch DrucKluft, die über eine Membran 20 auf das Federpaket wirkt, gelöst wird. Ueber eine automatische, stufenlose Nachstellung 21 steht der Federspeicherzylinder über einen Hebel 22 mit der Spreizvorrichtung 9 in Verbindung Die Nachstellvorrichtung besteht aus einem in Lingsrichtug wirkenden Freilauf 211, und einem mit axialem Spiel eingesetzten Bremsring 212, der auf einer Stange 213 gleich und nach Ueberwindung eines zulässigen Lüftspiels ein Nachgeben des Längsfreilaufs 211 bewirkt. Zum Auswechseln der Lamelle 14 wird ein Teil der Befestigungsschrauben, die die beiden Bremsgehäuseteile 4 und 5 zusammenhalten, geläst.the brake ring 8 cavities 16 and 17 are arranged in which the Cooling liquid is housed. Acts for mechanical actuation of the brake a spring-loaded cylinder 19 on the spreading device 9 via a gas line 18, which is released by compressed air, which acts on the spring assembly via a membrane 20. The spring-loaded cylinder is located above an automatic, stepless readjustment 21 Via a lever 22 with the spreading device 9 in connection. The adjusting device consists of a freewheel 211 acting in Lingsrichtug, and one with an axial one Game used brake ring 212, the same on a rod 213 and after overcoming a permissible clearance causes the longitudinal freewheel 211 to yield. To change the lamella 14 becomes part of the fastening screws that hold the two brake housing parts 4 and 5 stick together, let go.

Diese Schrauben 23 halten gleichzeitig den Deckel 24 und werden zum Auswechseln der Lamelle gelöst, so dass der Deckel 24 abgenommen werden kann. Zur axialen dos Abtriebsflansches 2 ist dieser mittels einer Schraube 25 an der Abtriebswelle 1 des Schaltgetriebes befestigt Nach Losen der Schraubo 25 und nachdem vorher die Kardanwelle ge1Ust wird, kann der Flansch soweit axial aus der Bremse herausgezogen werden, dass die Lamelle durch die durch den Deckel 24 abgeschlossene Oeffnung herausfällt.These screws 23 simultaneously hold the cover 24 and are used for Replacing the lamella is solved so that the cover 24 can be removed. To the axial dos output flange 2, this is by means of a screw 25 on the output shaft 1 of the gearbox attached After loosening the screw 25 and after the If the cardan shaft is used, the flange can be pulled axially out of the brake that the lamella falls out through the opening closed by the cover 24.

Bevor die neue Lamelle eingeschoben werden kann, muss der Deckel 26, an dem die Nachstellstange 213 befestigt ist,Before the new lamella can be pushed in, the cover 26, to which the adjusting rod 213 is attached,
