Description

Antrieb des Kühlerventilators für Motorfahrzeuge von der Motorwelle aus. Bei Eisenbahnfahrzeugen mit Schwerölniotorenantrieb muß man aus praktischen Gründen den Kühler auf das Dach des Fahrzeuges verlegen, da er an den Seitenflächen starken Beschädigungen ausgesetzt wäre. Den Antrieb des Ventilators kann man aus Gründen der Sicherheit und der Zugänglichkeit kaum mit Riemen erzielen. Man wird dazu am besten eine Zahnradübersetzung verwenden, und zwar zweckmäßig ein Kegelräderpaar, da die Achsen des Motors und des Ventilators senkrecht zueinander stehen, wenn man den Kühler mit Rücksicht auf die gute Ausnutzung des Lichtraumprofils wagerecht auf das Wagendach legt.Drive the radiator fan for motor vehicles from the engine shaft the end. In the case of railway vehicles with heavy oil engine drive, one has to be practical Reasons to move the radiator on the roof of the vehicle, as it is on the side surfaces would be exposed to severe damage. The drive of the fan can be turned off For reasons of safety and accessibility hardly achieve with straps. You will It is best to use a gear ratio for this purpose, specifically a pair of bevel gears, since the axes of the motor and the fan are perpendicular to each other, if one position the cooler horizontally, taking into account the good use of the clearance profile on the roof of the car.

Da der Ventilator eine gewisse Masse besitzt und ziemlich weit vom Motor entfernt ist; besteht die Gefahr, daß bei dein ruckweisen Anfahren des Schwerölinotors - das Anlassen geschieht mit Druckluft - die Antriebswelle, das Zahnradpaar oder den Ventilator selbst durch Trägheitswirkung der Ventilatormasse beschädigt wird. Aus diesem Grunde hat man bereits zwischen Motor und Ventilator eine ausrückbare Kupplung, z. B. Reibungskupplung, vorgesehen. Der Gegenstand der Erfindung besteht nun darin. daß diese Kupplung mit Motorstauung verbunden ist, daß sie erst eingerückt wird, wenn der Motor seine normale Drehzahl erreicht hat.Since the fan has a certain mass and is quite far from the Engine is removed; there is a risk that your jerky start-up of the heavy oil engine - the starting is done with compressed air - the drive shaft, the gear pair or the fan itself is damaged by the inertia of the fan mass. For this reason there is already a disengageable element between the motor and the fan Coupling, e.g. B. friction clutch provided. The subject matter of the invention is now in it. that this clutch is connected to engine stagnation, that it is only engaged when the engine has reached its normal speed.

Z'om Fahrzeugführer kann das Ausrücken der Kupplung beim Stillsetzen des Motors sehr leicht vergessen werden. Um dieses zti verhüten, wird der Mechanismus, der den Motor stillsetzt, so mit dem Ausrückhebel der Kupplung verbunden, daß gleichzeitig mit dem Stillsetzen des Motors auch die Kupplung ausgerückt wird; dabei kann aber die Abstellvorrichtung des Motors wieder in Betriebsstellung gebracht werden, ohne daß der Kupplungshebel aus der Ausrücklage bewegt wird.Z'om the driver can disengage the clutch when stopping of the engine can be easily forgotten. To prevent this, the mechanism which stops the engine, so connected to the release lever of the clutch that at the same time when the engine is stopped, the clutch is also disengaged; but can the engine shut-off device can be returned to its operating position without that the clutch lever is moved out of the disengaged position.

In der Zeichnung bedeutet beispielsweise a den Motor, b das Getriebe, c den Kühler, d den Ventilator, e das Kegelräderpaar zum Antrieb des Ventilators von der Motorwelle, f ist die ausrückbare Kupplung, g bedeutet die Brennstoffpumpe des Motors; der Hebel h hebt die Saugventile dieser Pumpe an, wodurch dieselbe abgestellt wird; der Hebel lt ist durch Stange k mit dem Handhebel i. verbunden. In der Stange k ist eine Schleife, die den Zapfen des Abstellhebels L der Reibungskupplung umschließt. Bewegt man den Hebel i nach rechts, so werden die Brennstoffpumpe g und die Reibungskupplung f gleichzeitig ausgerückt; dabei wird der Hebel L in der Endlage entsprechend fixiert, so daß er stehenbleibt, wenn die Brennstoffpumpe wieder durch Hebel i eingerückt wird. Dieselben Resultate lassen sich auch durch verschiedene andere konstruktiven Maßnahmen erzielen.In the drawing, for example, a denotes the motor, b the gearbox, c the radiator, d the fan, e the pair of bevel gears for driving the fan from the motor shaft, f the disengageable clutch, g the fuel pump of the motor; the lever lifts the suction valves of this pump, turning it off; the lever lt is by rod k with the hand lever i. tied together. In the rod k is a loop which encloses the pin of the shut-off lever L of the friction clutch. If you move the lever i to the right, the fuel pump g and the friction clutch f are disengaged at the same time; the lever L is fixed accordingly in the end position so that it stops when the fuel pump is engaged again by lever i. The same results can also be achieved by various other constructive measures.
