Description
Die Erfindung betrifft eine Motorkegelbremse, ■deren umlaufende Bremsscheibe als Gebläserad ausgebildet und zu diesem Zweck mit radial bzw. gekrümmten axial und radial verlaufenden Kanälen versehen ist. Eine derartig ausgebildete Motorbremse hat in doppelter Hinsicht Vorteile.' Einmal ergibt die lange Kanalwandung eine besondere große Fläche zur Abführung der Bremswärme, so daß also eine energische Kühlung der BremsflächenThe invention relates to a motor cone brake whose circumferential brake disc is designed as a fan wheel and for this purpose with radial or curved axially and radially extending channels is provided. An engine brake designed in this way has advantages in two ways. ' On the one hand, the long canal wall creates a special one large area to dissipate the heat from the brakes, so that the braking surfaces are effectively cooled
ίο erfolgt. Zugleich kann andererseits der Wirkungsgrad des Gebläses durch geeignete Ausbildung der Kanäle verhältnismäßig hoch getrieben werden, so daß neben der Bremskühlung auch die Belüftung des Motors besonders wirkungsvoll wird.ίο takes place. At the same time, on the other hand, the efficiency of the fan are driven relatively high by suitable design of the channels, so that in addition to the brake cooling, the ventilation of the engine is particularly effective.
Der Erfindung liegt die Aufgabe zugrunde, die Kühlung der Bremsfläche noch wirksamer zu gestalten. Zu diesem Zweck ist gemäß der Erfindung die Außenwand des Gebläserades in der Nähe der am Radumfang angeordneten Bremsfläche mit Durchbrüchen versehen, durch die ein Teil des Luftstromes den Bremsflächen zugeleitet wird. Auf diese Weise läßt sich auch unter den ungünstigsten Umständen, z. B. beim Einbau des Motors in das Innere von Winden, noch eine ausreichende Kühlung· erreichen.The invention is based on the object of making the cooling of the braking surface even more effective. For this purpose, according to the invention, the outer wall of the impeller is in the vicinity of the on the wheel circumference arranged braking surface provided with openings through which part of the Air flow is fed to the braking surfaces. In this way, even among the most unfavorable Circumstances, e.g. B. when installing the motor in the interior of winches, sufficient cooling reach.
Es sind bereits mit Lüfterflügeln versehene Bremssc'heiben bekannt, die in der Nähe, der Reibfläche Durchbrechungen aufweisen und durch die nach dem Lösen der Bremse die Kühlluft für die Reibflächen hindurchströmt. Hier dienen aber die Durchbrechungen nicht dazu, um einen Teilluftstrom abzuzweigen, sondern sie haben den Zweck, die Motorkühlluft über die Bremse dem Lüfterflügelkranz zuzuleiten. Im übrigen · ist hier die Bremsfläche nicht am Umfang des Reibrades angeordnet, sondern in dessen mittlerer Zone. Sie befindet sich also nicht, wie bei dem Erfindungsgegenstand, im Bereich der Lüfterflügel, wo die Kühlwirkung am intensivsten ist.Brake disks which are provided with fan blades and which are located in the vicinity of the friction surface are already known Have openings and through which the cooling air for the after releasing the brake Flows through friction surfaces. Here, however, the openings do not serve to divert a partial air flow branch off, but their purpose is to supply the motor cooling air via the brake to the fan blade ring forward. In addition, the braking surface is not arranged on the circumference of the friction wheel here, but in its central zone. she is therefore not, as is the case with the subject of the invention, in the area of the fan blades, where the Cooling effect is most intense.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt.Two exemplary embodiments of the invention are shown in the drawing.
Abb. ι zeigt eine Ausführung, bei der die Bremsfläche
als Kegel ausgebildet ist,
Abb. 2 eine solche mit hohlkegeliger Bremsfläche.Fig. Ι shows an embodiment in which the braking surface is designed as a cone,
Fig. 2 one with a hollow conical braking surface.
Auf der Motorwelle 1 ist das Gebläserad 2 mit der Nabe 3 befestigt. Es hat gekrümmte, etwa radial verlaufende Kanäle 4, deren Außenwand 5 zugleich Träger der Bremsfläche 6 einer kegeligen Bremse ist. Die Gegenbremsfläche sitzt am feststehenden Motorteil 7, beispielsweise am Gehäuse-•oder Motorlagerschild.The fan wheel 2 is fastened with the hub 3 on the motor shaft 1. It's curved, roughly radially extending channels 4, the outer wall 5 of which also supports the braking surface 6 of a conical Brake is. The counter-braking surface sits on the stationary motor part 7, for example on the housing • or Engine bearing shield.
Die Wandung 5 ist bei 8 unterbrochen, so daß der Zweigkanal 9 entsteht,-welcher Kühlluft an den Bremsflächen vorbeisaugt, so daß eine besonders energische Kühlung erzielt wird. Die gesamte Innenfläche der Kanäle dient ebenfalls zur Abführung der Bremswärme.The wall 5 is interrupted at 8, so that the branch channel 9 arises, -which cooling air to the Prevents braking surfaces so that particularly energetic cooling is achieved. The whole The inner surface of the channels is also used to dissipate the heat from the brakes.
Zur weiteren Steigerung der Kühlwirkung können im Bremsbelag Nuten oder Unterbrechungen vorgesehen werden, bzw. der Bremsbelag kann aus einzelnen Klötzen bestehen. Die Nuten, Unterbrechungen oder sonstigen Zwischenräume sind dann an die Kühlktftkanäle anzuschließen, so daß ein ständiger Luftstrom die Reibungswärme unmittelbar an der Entstehungsstelle abführt.To further increase the cooling effect, grooves or interruptions can be provided in the brake lining or the brake lining can consist of individual blocks. The grooves, interruptions or other spaces are then to be connected to the Kühlktftkanäle so that a constant flow of air dissipates the frictional heat directly at the point of origin.
Zwischen den einzelnen Kanälen bleiben Rippen stehen. Gemäß der weiteren Erfindung erhalten diese Rippen, in der Umfangsrichtung gesehen, ungleiche Abstände. Zum Beispiel können die Rippen paarweise enger und weiter auseinanderstehen. Das bringt niehrere Vorteile. Einmal können sich keine störenden Schwingungen ausbilden, entsprechend fallen auch Pfeiftöne und ähnliche Geräusche fort und schließlich gelangt die Kühlluft auch mit den Wänden der Bremsscheiben in intensivere Berührung. Die Anzahl der Rippen braucht durch ihre unregelmäßige Verteilung nicht geändert zu werden.Ribs remain between the individual canals. Obtained according to the further invention these ribs, seen in the circumferential direction, unequal distances. For example, the Ribs in pairs are closer and further apart. That brings no advantages. Can once no disturbing vibrations develop, whistling tones and the like also fall accordingly Noises go away and finally the cooling air also reaches the walls of the brake discs in more intense form Contact. The number of ribs does not need to be changed due to their irregular distribution to become.
