Abstract

Cooling blower arrangement between the rows of 'V' shaped cylinders in an I.C. engine. The housing of the cooling blower has a flexible bearing on one of the engine suction pipes and a liquid cooler which is detachable is fitted close to the inlet flow section of the guide wheel. The blower housing is sealed off by a flexible bearing on the suction pipe, and on the rear and front covers of the engine. This method attains a longer operating period of the blower shaft bearings whilst at the same time reducing the level of operating noise.

Description

Anordnung eines Kühlgebläses an einer Brennkraftmaschine Bei bekannten luftgekühlten Mehrzylinder- Brennkraftm aschinen mit V-förmiger Zylinderanordnung ist das Kühlgebläse am Motor zwischen den Zylinderreihen so angebracht, daß seine Achse zur Längsachse des Motors senkrecht oder leicht geneigt ausgeführt ist. Das Gehäuse des Gebläses ist fest mit dem Motorgehäuse verbunden. Durch das laufende Kühlgebläse vergrößern sich die Motorgeräusche, und die Motor-Vibrationen beeinträchtigen die Lebensdauer der Lagerung der Welle des Gebläselaufrades sowie auch die Lebensdauer des Flüssigkeitskühlers. Arrangement of a cooling fan on an internal combustion engine in known air-cooled multi-cylinder internal combustion engines with a V-shaped cylinder arrangement the cooling fan is attached to the engine between the rows of cylinders so that its Axis to the longitudinal axis of the motor is perpendicular or slightly inclined. That The fan housing is firmly connected to the motor housing. Through the running Cooling fans increase engine noise and reduce engine vibration the service life of the bearing of the shaft of the fan impeller as well as the service life of the liquid cooler.

Aufgabe der Erfindung ist die Verlängerung der Betriebszeiten der Lager von Gebläsewellen bei gleichzeitiger Senkung der Motorgeräusche. The object of the invention is to extend the operating times of the Bearing of fan shafts while reducing engine noise.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Gehäuse des Kühlgebläses elastisch an einer Saugleitung des Motors gelagert ist und daß in der Nähe des Einströmteils eines Leitrades mindestens ein abnehmbarer Flüssigkeitskühler angeordnet ist. This object is achieved according to the invention in that the housing the cooling fan is elastically mounted on a suction line of the engine and that at least one removable liquid cooler near the inflow part of a stator is arranged.

Dabei kann das Gehäuse des Gebläses vorteilhaft einesteils durch die elastische Lagerung an der Saugleitung, andernteils am hinteren Deckblech und am vorderen Deckel des Motors abgedichtet werden. The housing of the fan can advantageously in part through the elastic mounting on the suction line, on the other hand on the rear cover plate and sealed on the front cover of the engine.

Eine bevorzugte Anordnung gemäß der Erfindung wird im folgenden anhand der Zeichnung genauer beschrieben. Es zeigen: Fig. 1 einen Querschnitt durch den Kühler des Gebläses und seine elastische Lagerung an der Saugleitung am ,hinteren und am vorderen Deckel des Motors, Fig. 2 einen Längsschnitt durch das Kühlgebläse und seine elastische Lagerung am vorderen und am hinteren Deckblech des Motors. A preferred arrangement according to the invention will be described below with reference to the drawing described in more detail. They show: FIG. 1 a cross section through the The fan cooler and its elastic mounting on the suction line at the rear and on the front cover of the engine, FIG. 2 shows a longitudinal section through the cooling fan and its elastic mounting on the front and rear cover plate of the engine.

Das Kühlgebläse 1 ist durch sein Gehäuse 2 über elastische Unterlagen 9 an einer Saugleitung 3, 3' des Motors befestigt. Oberhalb des Eingangsteils 4 des Leitrades 5 ist mindestens ein Flüssigkeitskühler 6 angeordnet, der elastisch am Gebläsegehäuse 2 montiert ist. The cooling fan 1 is through its housing 2 on elastic pads 9 attached to a suction line 3, 3 'of the engine. Above the entrance part 4 of the stator 5 is arranged at least one liquid cooler 6, which is elastic is mounted on the fan housing 2.

Der Kühler 6 kann so geformt sein, daß ein Teil oder die gesamte zur Aufrechterhaltung der Betriebstemperatur des Motors notwendige Kühlluft durchströmt. Das Gehäuse 2 ist durch elastische Unterlagen 9, 9' am hinteren Deckblech 7 des Motors und am vorderen Deckel 8 des Motors gelagert. Die elastische Lagerung des Kühlgebläses 1 bildet gleichzeitig die Abdichtung des Raumes oberhalb der Zylinder und der Zylinderköpfe.The cooler 6 may be shaped so that part or all of the The necessary cooling air flows through to maintain the operating temperature of the motor. The housing 2 is by elastic pads 9, 9 'on the rear cover plate 7 of the Motor and mounted on the front cover 8 of the motor. The elastic mounting of the Cooling fan 1 also forms the seal of the space above the cylinder and the cylinder heads.

Die Vorteile der Anordnung des Kühlgebläses nach der Erfindung liegen in einer erhöhten Lebensdauer der Lagerung der Welle des Laufrades des Kühlgebläses und des Flüssigkeitskühlers. The advantages of the arrangement of the cooling fan according to the invention are in an increased service life of the bearing of the shaft of the impeller of the cooling fan and the liquid cooler.
