Seilbefestigungspunkt.Rope attachment point.

Patentiert im Deutschen Reiche vom 25. Oktober 1908 ab.Patented in the German Empire on October 25, 1908.

Aus konstruktiven Gründen ist es bei Treidellokomotiven oft nicht möglich, den Seilbefestigungspunkt(Mast) in der Mitte des Fahrzeuges anzubringen, so daß er nach der Seite verlegt werden muß. Durch eine solche Anordnung kann Entgleisungsgefahr entstehen. Wenn nämlich, wie bei dem in Fig. ι abgebildeten Fahrzeug der Angriffspunkt A des Seilzuges 5 am vorderen Ende des FahrzeugesFor structural reasons, it is often not possible with towing locomotives to attach the rope attachment point (mast) in the middle of the vehicle, so that it has to be moved to the side. Such an arrangement can lead to a risk of derailment. If namely, as in the vehicle shown in Fig. Ι the point of application A of the cable 5 at the front end of the vehicle

ίο wasserseitig von der Schwerpunktslängsebene liegt, so wird die vordere Achse durch die Querkraft Q des Seilzuges stärker an die wasserseitige Schiene gedrückt als die hintere Achse; außerdem wird die vordere, Achse an diese Schiene noch durch ein Schlingermoment gedrängt, das sich aus der Längskraft L des Seilzuges und ihrem Abstand 1 von dem Schwerpunkt des Fahrzeuges zusammensetzt, während die hintere Achse durch dieses Moment von der Schiene fortgedrängt wird. Wenn hierbei der Angriffspunkt des Seilzuges außerhalb des Fahrzeuges angeordnet werden muß (um dicht an der Uferkante zu liegen), so nimmt das Schlingermoment und damit die Entgleisungsmöglichkeit noch zu.ίο is on the water side of the longitudinal plane of the center of gravity, the front axle is pressed more strongly against the water-side rail than the rear axle by the transverse force Q of the cable pull; In addition, the front axle is pushed against this rail by a rolling moment, which is composed of the longitudinal force L of the cable and its distance 1 from the center of gravity of the vehicle, while the rear axle is pushed away from the rail by this moment. If the point of application of the cable pull has to be arranged outside the vehicle (in order to be close to the bank edge), the rolling moment and thus the possibility of derailment increase.

Liegt der Angriffspunkt des Seilzuges landseitig von der Schwerpunktslängsebene und dabei am hinteren Ende des Fahrzeuges, so wird die hintere Achse wesentlich stärker als die vordere an die wasserseitige Schiene gedrückt. Auch hierdurch kann eine Entgleisung herbeigeführt werden.If the point of application of the cable pull is on the land side of the longitudinal plane of the center of gravity and while at the rear end of the vehicle, the rear axle is much stronger than the front one pressed against the rail on the water side. This can also lead to a derailment be brought about.

Um diese Gefahr zu beseitigen, hat man die stärker quer verdrängte Achse stärker belastet, um ihr das Aufklettern auf den Schienenkopf zu erschweren. Das ist aber deshalb unvorteilhaft, weil dadurch eine Entlastung der Schiene von den Querschüben nicht erreicht ■ wird und außerdem häufig totes Ballastgewicht verwendet werden muß. Zweckmäßig ist es, das Fahrzeug so zu bauen, daß alle Achsen gleichmäßig bzw. entsprechend ihrer senkrechten Belastung quer beansprucht werden, vielleicht sogar die hinteren Achsen, die weniger zur Steuerung des Fahrzeuges beitragen, etwas mehr als die vorderen.In order to eliminate this danger, the more transversely displaced axis was loaded more heavily, to make it difficult for her to climb onto the rail head. However, this is disadvantageous because it relieves the burden on the Rail is not reached by the transverse thrusts ■ and also often dead ballast weight must be used. It is useful to build the vehicle so that all axles are loaded evenly or transversely according to their vertical load, maybe even the rear axles, which contribute less to the control of the vehicle, something more than the front ones.

Entsprechend der Erfindung wird dies dadurch erreicht, daß der Angriffspunkt des Seilzuges am Fahrzeug bei Anordnung des Seilbefestigungspunktes wasserseitig von der Schwerpunktslängsebene des Fahrzeuges hinter die Schwerpunktsquerebene (Fig. 2) und bei Anordnung des Seilbefestigungspunktes landseitig von der Schwerpunktslängsebene ν ο r die Schwerpunktsquerebene (Fig. 3) verlegt ist, zweckmäßig so, daß der Seilzug annähernd durch den Schwerpunkt des Fahrzeuges geht. Bei dieser Anordnung wird diejenige Achse, welche durch die Querkraft stärker an die Schiene gedrängt wird, durch das Schlingermoment von dieser Schiene fortgedrängt. IAccording to the invention, this is achieved in that the point of application of the cable pull on the vehicle with the arrangement of the rope attachment point on the water side from the longitudinal plane of the center of gravity of the vehicle behind the transverse plane of the center of gravity (Fig. 2) and when arranging the rope attachment point landside from the longitudinal plane of the center of gravity ν ο r the transverse plane of the center of gravity (Fig. 3) is relocated, expediently so that the cable pull approximately goes through the center of gravity of the vehicle. With this arrangement, the axis that is affected by the transverse force becomes stronger is pushed against the rail, pushed away from this rail by the rolling moment. I.

be relocated additionally when the direction of travel is reversed. Two separate rope attachments can be arranged for this purpose. This double version can be reported when the rope attachment point is adjustable and its ability to move in the horizontal plane can be blocked. Suitable for the invention is a mast which can be rotated about a vertical axis if a locking device is attached to the mast so that the possibility of movement of the rope attachment point can be blocked in the horizontal plane. In the embodiment according to FIG. 4, a mast a is placed on an underframe b which is rotatable about a vertical axis. The mast itself can be rotated around a horizontal axis. The underframe b has locking devices c by means of which its horizontal rotation can be blocked. Another embodiment consists in that a fixed rail (Fig. 5) is attached to the vehicle, along which the cable attachment point is moved and on which it can be fixed. This rail can be a fixed arm of a fixed mast, and can also be designed in such a way that the rope attachment point is guided in a slot. You can also attach a fixed mast to the vehicle and provide it with a boom that can be rotated about a horizontal axis perpendicular to the longitudinal direction of the vehicle. If the boom is prevented by stops on the mast from sinking down completely to the horizontal position, it will be shifted automatically when the direction of travel is reversed. Such a device is shown in Fig. 6, α is the fixed mast and b the boom rotatable about the horizontal axis c, d are the stops that prevent the boom from falling into the horizontal position.
