Description
Die Erfindung betrifft eine mit einem Hohlraum für den Durchgang eines Kühlmittels versehene Bremsbacke.The invention relates to one with a cavity for the passage of a coolant provided brake shoe.
Derartige Bremsbacken sind bekannt. Sie finden als Außenbremsbacken oder als Innenbremsbacken Verwendung.Such brake shoes are known. You can find them as external brake shoes or as internal brake shoes Use.
In der Regel arbeiten sie mit einer Bremstrommelausfütterung zusammen, die aus nichtmetallischem Material besteht. Es ist aber ohne weiteres möglich, Bremstrommel und Bremsbacke aus Metall oder aber die Bremstrommel allein ganz aus nichtmetallischem Material anzufertigen.As a rule, they work with a brake drum lining made of non-metallic material. But it is easily possible, brake drum and brake shoe made of metal or the brake drum to be made entirely from non-metallic material.
Da beim Bremsen sehr hohe Temperaturen entstehen, ist es bekannt, die Bremsbacke hohl auszuführen und durch den Hohlraum ein Kühlmittel, beispielsweise Wasser, hindurchzuschicken. Since braking occurs at very high temperatures, it is known that the brake shoe to be hollow and to send a coolant, for example water, through the cavity.
Eine solche Bremsbacke muß so ausgebildetSuch a brake shoe must be designed in this way
ao sein, daß die Materialschicht, die zwischen Bremsfläche und Kühlfläche liegt, nicht allzu dick ist, weil sonst das Kühlmittel nicht wirksam werden kann.ao be that the material layer that lies between the braking surface and the cooling surface is not too is thick, otherwise the coolant cannot be effective.
Nach einiger Betriebszeit kann die Abnützung der Bremsbacke so weit gehen, daß der Hohlraum, der von dem Kühlmittel durchströmt wird, bloßgelegt wird. Damit würde die ganze Bremsbacke unbrauchbar. Die bisher nach den eben gemachten Ausführungen 30. gebauten Bremsbacken müssen infolgedessen weggeworfen werden und bedeuten daher einen unnötigen Materialverlust. Dem soll durch die vorliegende Erfindung abgeholfen werden, und zwar dadurch, daß die Bremsbacke aus einem Grundkörper besteht, der einen Hohlraum für den Durchfluß des Kühlmittels aufweist und einen abnehmbaren, gut wärmeleitenden Teil besitzt, der die Bremsfläche bildet.After a period of operation, the wear of the brake shoe can go so far that the cavity through which the coolant flows is exposed. So that would the entire brake shoe is unusable. The ones so far based on what has just been said 30. As a result, built brake shoes have to be thrown away and therefore mean unnecessary material loss. The present invention is intended to remedy this in that the brake shoe consists of a base body which has a cavity for the flow of coolant has and has a removable, highly thermally conductive part, which the braking surface forms.
Der auswechselbare Teil kann so eingerichtet sein, daß er unmittelbar von dem Kühlmittel gekühlt wird. Dann wird nach Wegnahme dieses ,auswechselbaren Teiles der Hohlraum in der Bremsbacke bloßgelegt. Dies ist vorteilhaft, weil dadurch Unreinigkeiten, die in den Hohlraum gelangen und sich an den Seitenwänden desselben absetzen, leicht entfernt werden können.The replaceable part can be arranged so that it is directly from the coolant is cooled. Then, after removing this replaceable part, the The cavity in the brake shoe is exposed. This is advantageous because it causes impurities, which get into the cavity and settle on the side walls of the same, easily can be removed.
Die Einrichtung kann jedoch auch so getroffen werden, daß der auswechselbare Teil nicht bis unmittelbar an den Hohlraum heranreicht. Im Interesse guter Kühlung müßte dann die Zwischenwand zwischen auswechselbarem Teil und eigentlicher Bremsbacke sehr dünn gehalten sein.However, the device can also be made so that the replaceable part does not come right up to the cavity. In the interest of good cooling would have to then the partition between the replaceable part and the actual brake shoe very much be kept thin.
Wenn der auswechselbare Teil den Hohlraum in der Bremsbacke unmittelbar abdeckt, dann muß zwischen ihm und der Bremsbacke eine Abdichtungsschicht eingelegt werden, die den Durchtritt des Kühlmittels verhindert. If the replaceable part directly covers the cavity in the brake shoe, then a sealing layer must be inserted between it and the brake shoe, which prevents the passage of the coolant.
Ein weiterer Vorteil des auswechselbaren Teiles der Bremsbacke besteht darin, daß es möglich ist, den Grundkörper der Bremsbacke und die auswechselbare Bremsfläche aus verschiedenem Material anzufertigen. So kann man beispielsweise den nicht auswechselbaren Teil der Bremsbacke aus einem Leicht-Another advantage of the replaceable part of the brake shoe is that it it is possible to make the base body of the brake shoe and the exchangeable braking surface from different materials. So for example, the non-replaceable part of the brake shoe can be made from a lightweight
