Abstract
Description
Die Abdeckwand besteht aus einzelnen Wälzkörpern 2 zylinderischer Grundform, die die gesämte Länge des Kühlers 1 durchsetzen, und die stirnseitig in Vertikalführungen 3 U-förmigen Querschnitts geführt sind. Zum Transport der Wälzkörper 2 in die Abdeckstellung sind sie aus einem unterhalbzdesAnströmbereiches des Kühlers 1 befindlichen Speicherbehälter 4 mittels der Rotationsfördereinrichtung, die eine Reibtrommel 5 und einen nicht näher dargestellten Antrieb umfaßt, in den Führungen 3 hochförderbar, wobei die hochgeförderten Wälzkörper 2 unter linienförmiger Berührung der einander zugewandten Umfangsflächen aufgrund ihrer Gewichtskraft dichtend aufeinander liegen. In bevorzugter Ausführung weisen die Wälzkörper 2 einen rohrförmigen Querschnitt auf und bestehen aus Aluminium. Insbesondere bei derartigen, relativ leichtgewichtigen Wälzkörpern 2 kann es erforderlich sein, den oberen Wälzkörper 2 durch Rückstellfedern gegen die Hochförderrichtung zu belasten, um unter allen Betriebsbedingungen eine geschlossene Abdeckwand sicherstellen zu können. The cover wall consists of individual rolling elements 2 cylindrical Basic shape that enforce the entire length of the cooler 1, and the end face are guided in vertical guides 3 U-shaped cross-section. For transporting the rolling elements 2 in the cover position, they are from an area below the flow area of the cooler 1 located storage container 4 by means of the rotary conveyor, which a Includes friction drum 5 and a drive, not shown, in the guides 3 can be promoted upwards, with the highly promoted Rolling body 2 under linear Contact of the circumferential surfaces facing each other to form a seal due to their weight lie on one another. In a preferred embodiment, the rolling elements 2 have a tubular shape Cross-section and are made of aluminum. Especially with such, relatively lightweight rolling elements 2 may require the upper rolling elements 2 to load by return springs against the upward direction of conveyance to under all To be able to ensure a closed cover wall operating conditions.
Anstelle der Reibtrommel 5 können auch zwei einzelne Reibräder oder alternativ zwei Antriebsritzel für die Rotationsfördereinrichtung vorgesehen sein. Im letzteren Fall müssen die Zahnlücken der Antriebsritzel jedoch exakt auf den Durchmesser der Wälzkörper 2 abgestimmt sein. Instead of the friction drum 5, two individual friction wheels or alternatively, two drive pinions can be provided for the rotary conveyor. In the latter case, however, the tooth gaps of the drive pinion must exactly match the Be matched to the diameter of the rolling elements 2.
Bei jeder der Ausführungsformen sind die Wälzkörper 2 durch Drehrichtungsumkehr der Rotationsfördereinrichtung aus der Abdeckstellung in den Speicherbehälter 4 rückförderbar. In each of the embodiments, the rolling elements 2 are reversed in the direction of rotation the rotary conveyor from the covering position into the storage container 4 returnable.
Damit bei Ausfall des Antriebes und abgedecktem Kühler keine dauerhafte Überhitzung des Kühlwassers erfolgen kann, die häufig mit erheblichen Folgeschäden einhergeht, sind die seitlichen Schenkel der Führungen 3 in einem Abschnitt oberhalb der vorgesehenen maximalen Stapelhöhe der Wälzkörper 2 im Speicherbehälter 4 und unterhalb des Anströmbereiches des Kühlers 1 einseitig unterbrochen und funktionell durch eine schwenkbare Klappe 6 ersetzt. Die Klappe 6 wird im Normalbetrieb durch eine Feder 7 gegen einen Anschlag gedrückt und somit in ihrer Ausgangsstellung gehalten. Tritt eine Überhitzung des Kühlwassers auf, so wird die Klappe 6 mittels eines Stellgliedes 8 in eine durch unterbrochene Linien angedeutete Freigabestellung in einen Fangkasten 4a des Speicherbehälters 4 hineingeschwenkt. Das Stellglied 8 kann von einem thermostatisch angesteuerten Magnetschalter oder Stellmotor, oder ggf. auch von einem unmittelbar im Kühlmittelstrom angeordneten Dehnstoffelement gebildet werden, das die Stellkräfte selbst aufbringt. Die Verwendung eines Dehnstoffelementes ist dahingehend als vorteilhaft anzusehen, daß es als besonders störungssicher einzustufen ist. So if the drive fails and the cooler is covered, there is no permanent Overheating of the cooling water can occur, often with considerable consequential damage goes hand in hand, the side legs of the guides 3 are in a section above the intended maximum stack height of the rolling elements 2 in the storage container 4 and below the flow area of the cooler 1 interrupted on one side and functional replaced by a pivoting flap 6. The flap 6 is through in normal operation a spring 7 is pressed against a stop and thus held in its starting position. If the cooling water overheats, the flap 6 is activated by means of an actuator 8 in a release position indicated by broken lines in a catch box 4a of the storage container 4 swiveled in. The actuator 8 can be a thermostatic controlled magnetic switch or servomotor, or possibly also by one directly In the coolant flow arranged expansion element are formed, which the actuating forces applies himself. The use of an expansion element is advantageous in this regard to see that it is to be classified as particularly fail-safe.
Die geöffnete Klappe 6 bildet gemeinsam mit einer Leiteinrichtung 9 einen Schacht, durch den oberhalb der Leiteinrichtung 9 befindliche Wälzkörper 2 aufgrund ihres Gewichts in den Speicherbehälter 4 hinunterfallen und somit für eine erneute Beschickung der Rotationsfördereinrichtung zur Verfügung stehen. Da die Leiteinrichtung 9 den Umfang der Reibtrommel 5 nach oben hin abdeckt, ist gleichzeitig sichergestellt, daß die niederfallenden Wälzkörper 2 nur von der den Führungen 3 abgewandten Umfangsseite der Reibtrommel 5 her zugeführt werden können. The opened flap 6 forms together with a guide device 9 a shaft through the rolling elements located above the guide device 9 2 fall down due to their weight in the storage container 4 and thus for a renewed loading of the rotary conveyor are available. There the guide device 9 covers the circumference of the friction drum 5 towards the top, is at the same time ensures that the falling rolling elements 2 only from the guides 3 remote peripheral side of the friction drum 5 can be fed forth.
Selbstverständlich kann die erfindungsgemäße Abdeckeinrichtung nicht nur, wie in diesem Ausführungsbeispiel ausgeführt, zwischen zwei Kühlerstufen la und 1 b angeordnet sein. Sie eignet sich vielmehr für jede Art eines aufrecht im Motorraum angeordneten Kraftfahrzeugkühlers. Of course, the cover device according to the invention cannot only, as stated in this embodiment, between two cooler stages la and 1 b be arranged. Rather, it is suitable for any type of upright im Motor compartment arranged motor vehicle radiator.
Allen denkbaren Ausführungsformen dieser Abdeckeinrichtung ist über die verbesserte Temperaturbeständigkeit hinaus noch der Vorzug zu eigen, daß durch die mit dem Fördervorgang verbundene Relativdrehung der einzelnen Wälzkörper 2 gegeneinander eine Selbstreinigungswirkung verbunden ist, so daß in der Regel keine Reinigung der Abdeckeinrichtung von Ver- schmutzungen, wie Insektenrückständen oder dgl., erforderlich sein wird. All conceivable embodiments of this cover device are over the improved temperature resistance also has the advantage that through the relative rotation of the individual rolling elements 2 against each other associated with the conveying process a self-cleaning effect is connected, so that usually no cleaning the cover device of dirt, such as insect residues or the like., Required will be.
