Mechanische Notlösevorrichtung für FederspeicherbremsenMechanical emergency release device for spring brakes

Beschreibung:Description:

Die Erfindung betrifft eine mechanische Notlösevorrichtung für Federspeicherbremsen, bei denen die Betätigungsstange des Bremsgerätes über eine gelenkige Verbindung auf einen die Bremsmittel in gegenseitigen Eingriff bringenden bzw. voneinander lösenden zweiarmigen Bremshebel einwirkt.The invention relates to a mechanical emergency release device for spring-loaded brakes, in which the actuating rod of the braking device acts via an articulated connection on a two-armed brake lever which brings the braking means into mutual engagement or disengages them from one another.

Aus den DE-OS 31 01 6O8 und 31 13 586 bekannte Löseeinrichtungen für Federspeicherbremszylinder arbeiten mit Kugeln oder Stiften, von denen die im Kolben axial verschiebbare Kolbenstange verriegelt wird. Das Aufheben dieser Stellung erfolgt durch das Verdrehen der Kolbenstange oder eines ihr zugeordneten Gegenringes, was beträchtliche Stellkräfte erforderlich macht. Außerdem sindRelease devices known from DE-OS 31 01 608 and 31 13 586 for spring brake cylinders work with balls or pins, which lock the piston rod, which can be moved axially in the piston. This position is released by turning the piston rod or a counter ring associated with it, which requires considerable actuating forces. In addition,

- 2 - 121/671- 2 - 121/671

die mit den bisher angewendeten Verriegelungselementen zu übertragenden Kräfte begrenzt, so daß solche Löseeinrichtungen für hoch beaufschlagte Bremsen nicht in Frage kommen.the forces that can be transmitted with the locking elements used to date are limited, so that such release devices are not suitable for brakes subject to high loads.

Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, mit der sich im drucklosen Zustand befindliche angebremste Federspeicherbremsen ohne besondere Hilfsmittel manuell leicht lösen lassen, damit beispielsweise das Abschleppen von mit ihnen ausgerüsteten Fahrzeugen jederzeit möglich ist. Hierbei kommt es vor allem auf die Eignung für sehr hohe Bremsbetätigungskräf te an, wie sie hauptsächlich im Schienenfahrzeugbetrieb auftreten. Ferner soll die angestrebte Notlösevorrichtung nach dem Wiederherstellen der Funktionstüchtigkeit der Bremsanlage selbsttätig in ihre Ausgangsstellung zurückkehren, um daraufhin unmittelbar wieder verfügbar, zu sein.The object of the invention is to create a device with which spring brakes in a pressureless state can be easily released manually without special aids, so that, for example, vehicles equipped with them can be towed at any time. The main thing here is suitability for very high brake actuation forces, such as those that mainly occur in rail vehicle operation. Furthermore, the desired emergency release device should automatically return to its starting position after the functionality of the braking system has been restored, in order to be immediately available again.

Als Lösung der gestellten Aufgabe wird die in den Ansprüchen gekennzeichnete Konstruktion vorgeschlagen.As a solution to the problem posed, the construction characterized in the claims is proposed.

Ein Ausführungsbeispiel des Anmeldungsgegenstandes ist in den Zeichnungen dargestellt. Darin zeigenAn embodiment of the subject matter of the application is shown in the drawings.

- 3 - 121/671- 3 - 121/671

Fig. 2 dieselbe Federspeicherbremse in der notgelösten Stellung.Fig. 2 the same spring brake in the emergency released position.

Wie insbesondere aus Fig. 1 der Abbildungen hervorgeht, sind im Gehäuse 1 des für ein Schienenfahrzeug bestimmten Bremsgerätes 2 ein Hydraulikzylinder 3 mit einem darin beweglichen Steuerkolben 4 untergebracht. Die sich in einer Betätigungsstange 5 fortsetzende Kolbenstange 6 nimmt den von einer Schraubenfeder 7 belasteten Federteller 8 auf und wirkt über eine gelenkige Verbindung 9 auf einen zweiarmigen Bremshebel 10 ein. Von diesem in einer am Gehäuse 1 des Bremsgerätes 2 befestigten Lagerhalterung 11 beweglich abgestützten Bremshebel 10 werden über eine weitere gelenkige Verbindung 12 die beidseitig einer Bremsscheibe 13 angeordneten Bremsbacken 14 betätigt, wobei sie nach der jeweiligen Stellung des Steuerkolbens 4 im Hydraulikzylinder 3 mit der Bremsscheibe 13 in Eingriff gelangen oder sich von ihr lösen.As can be seen in particular from Fig. 1 of the figures, a hydraulic cylinder 3 with a control piston 4 that can move in it is housed in the housing 1 of the braking device 2 intended for a rail vehicle. The piston rod 6, which continues in an actuating rod 5, takes up the spring plate 8 loaded by a coil spring 7 and acts on a two-armed brake lever 10 via an articulated connection 9. This brake lever 10, which is movably supported in a bearing holder 11 attached to the housing 1 of the braking device 2, actuates the brake shoes 14 arranged on both sides of a brake disk 13 via a further articulated connection 12, whereby they engage with the brake disk 13 or disengage from it depending on the respective position of the control piston 4 in the hydraulic cylinder 3.

Da die auf die Bremsbacken 14 ausgeübte Bremskraft von der Schraubenfeder 7 des Bremsgerätes 2 erzeugt wird, gelangen die Bremsbacken 14 stets in die Bremsstellung, sobald sich im Hydraulikzylinder 3 ein druckloser Zustand einstellt. Letzteres tritt demnach auch beim Ausfall einer das Bremsgerät 2 versorgenden Hydraulikanlage ein, woraufhin das mit dem Bremsgerät 2 ausgestattete FahrzeugSince the braking force exerted on the brake shoes 14 is generated by the coil spring 7 of the braking device 2, the brake shoes 14 always reach the braking position as soon as a pressureless state occurs in the hydraulic cylinder 3. The latter therefore also occurs in the event of a failure of a hydraulic system supplying the braking device 2, whereupon the vehicle equipped with the braking device 2

zwangsläufig angebremst und dadurch nicht mehr zu bewegen ist. Will man es jedoch beispielsweise zu Reparaturzwekken abschleppen, muß seine Federspeicherbremse zu diesem Zweck notgelöst werden.inevitably braked and can therefore no longer be moved. However, if you want to tow it for repair purposes, for example, the spring brake must be released for this purpose.

Im vorliegenden Falle besteht die Notlösevorrichtung darin, daß sich der Drehpunkt 15 des zweiarmigen Bremshebels 10 in der die Bremswirkung hervorrufenden axialen Richtung der Betätigungsstange 5 des Bremsgerätes 2 verschieben läßt. Hierfür ist der Bremshebel 10 auf seiner Lagerwelle 16 exzentrisch angeordnet. Außerdem nimmt die La"-gerwelle 16 einen seitlich auf ihr befestigten Notlösehebel 17 auf, der entsprechend Fig. 1 im Regelbetrieb der Federspeicherbremse mit seinem freien Ende an einer federbelasteten Sperrklinke 18 anliegt. Befinden sich nun die Bremsbacken 14 aufgrund einer technischen Störung im drucklosen Zustand des Bremsgerätes 2 mit der Bremsscheibe 13 in Eingriff, so kann die Sperrklinke 18 durch Handbetätigung eines an-ihr angebrachten Zugseiles 19 aus ihrer Normalstellung herausbewegt werden, womit sie den Notlösehebel 17 freigibt und dieser sich bis zum Anschlag am Gehäuse 1 des Bremsgerätes 2 in der Zeichnung nach oben bewegt. Bei dieser in Fig. 2 gezeigten Stellung hat sich der Drehpunkt 15 des Bremshebels 10 gleichzeitig nach unten verschoben, was dann das Lösen der Bremsbacken 14 von der Bremsscheibe 13 bewirkt hat. InfolgedessenIn the present case, the emergency release device consists in the fact that the pivot point 15 of the two-armed brake lever 10 can be moved in the axial direction of the actuating rod 5 of the braking device 2, which causes the braking effect. For this purpose, the brake lever 10 is arranged eccentrically on its bearing shaft 16. In addition, the bearing shaft 16 accommodates an emergency release lever 17 attached to it on the side, which, according to Fig. 1, rests with its free end on a spring-loaded pawl 18 during normal operation of the spring brake. If the brake shoes 14 are now in engagement with the brake disc 13 due to a technical fault when the brake device 2 is depressurized, the pawl 18 can be moved out of its normal position by manually operating a pull cable 19 attached to it, thereby releasing the emergency release lever 17 and causing it to move upwards in the drawing until it stops on the housing 1 of the brake device 2. In this position shown in Fig. 2, the pivot point 15 of the brake lever 10 has simultaneously moved downwards, which then causes the brake shoes 14 to be released from the brake disc 13. As a result,

- 5 - 121/671- 5 - 121/671

ist nun die Federspeicherbremse notgelöst und das Fahrzeug kann in der bezweckten Weise freizügig bewegt werden. The spring brake is now released and the vehicle can be moved freely in the intended manner.

Ist der Fehler an der Bremsanlage behoben, soll die Notlösevorrichtung nach den Zielen der Erfindung selbsttätig wieder in ihre im Regelbetrieb der Federspeicherbremse eingenommene Ausgangsstellung zurückgeführt werden. Hierzu dient eine zwischen dem'Bremsgerät 2 und dem Notlösehebel 17 geschaffene Wirkverbindung, die von einem am Bremsgerät 2 angelenkten Kniehebel 20 hergestellt wird, der einenends an einem vom Federteller 8 des Bremsgerätes 2 ausgehenden Mitnehmer 21 und anderenends an einer Nase 22 des Notlösehebels 17 angreift. Hebt sich also bei Wiederinbetriebnahme des Bremsgerätes 2 dessen Steuerkolben 4 im Hydraulikzylinder 3 und damit der Federteller 8 vom Boden des Gehäuses 1 ab, wird der. Kniehebel 20 vom Mitnehmer 21 so betätigt, daß er über die Nase 22 den Notlösehebel 17 bis zum erneuten Einrasten der Sperrklinke 18 bewegt. In diesem Zusammenhang ist sodann auch der Drehpunkt 15 des Bremshebels 10 in seine aus Fig. 1 ersichtliche Lage zurückgekehrt, womit sich anschließend der Regelbetrieb der zur Beschreibung gelangten Federspeicherbremse wieder aufnehmen läßt.If the fault in the brake system has been rectified, the emergency release device should, according to the aims of the invention, automatically return to its initial position, which it assumed during normal operation of the spring brake. This is achieved by an operative connection between the brake device 2 and the emergency release lever 17, which is established by a knee lever 20 hinged to the brake device 2, which at one end engages a driver 21 extending from the spring plate 8 of the brake device 2 and at the other end engages a nose 22 of the emergency release lever 17. If, when the brake device 2 is put back into operation, its control piston 4 in the hydraulic cylinder 3 and thus the spring plate 8 lifts off the bottom of the housing 1, the knee lever 20 is actuated by the driver 21 in such a way that it moves the emergency release lever 17 via the nose 22 until the locking pawl 18 engages again. In this context, the pivot point 15 of the brake lever 10 then also returns to its position shown in Fig. 1, whereby the control operation of the spring brake described can then be resumed.
