Description

Schutzstange gegen Zusammenstoß für Kraftfahrzeuge. Die Erfindung betrifft eine Schutzstange für Kraftfahrzeuge, wie diese an der Vorder-und oft auch an der Rückseite des Fahrzeuges angebracht werden, um bei Zusammenstößen mit anderen Fahrzeugen eine Beschädigung des eigenen Wagens zu verhindern.Protective bar against collision for motor vehicles. The invention concerns a protective bar for motor vehicles, like this one at the front and often too be attached to the rear of the vehicle to avoid collisions with others To prevent vehicles from damaging their own vehicle.

Diese Stangen wurden bisher entweder aus, kreisförmigen Röhren oder aus im Querschnitt C förmigen Eisenstangen hergestellt.These rods were previously made either of, or circular tubes made of iron bars with a C-shaped cross-section.

Gemäß der Erfindung erhalten diese Schutzstangen Tropfenquerschnitt, wobei vorteilhaft im senkrechten Querschnitt der verdickte Teil -nach vorn liegt. Hierdurch werden gleichzeitig zwei Wirkungen erreicht. Einmal wird der Luftwiderstand dieser völlig freien, am Wagen angebrachten Vorrichtung herabgesetzt. ferner `wird aber auch deren Festigkeit erhöht, da der Tropfenquerschnitt gerade in wagerechter Richtung das größte Widerstandsmoment besitzt. Die Zeichnung -zeigt ein Ausführungsbeispiel der Erfindung. An der Vorderseite des Wagens w ist starr oder federnd die Schutzstange s befestigt, die in Abb. t im Schnitt, in Abb.2 in der Draufsicht dargestellt und im senkrechten (Querschnitt tropfenförmig gestaltet ist. Die Festigkeit dieser Schutzvorrichtung ist also in wagerechter Ebene am größten.According to the invention, these protective rods have a drop cross-section, the thickened part advantageously lying forward in the vertical cross-section. This achieves two effects at the same time. Once there is air resistance this completely free device attached to the carriage. also `will but their strength is also increased, since the drop cross-section is horizontal Direction has the greatest section modulus. The drawing shows an embodiment the invention. The protective bar is rigid or resilient at the front of the carriage w s attached, shown in Fig. t in section, in Fig.2 in plan view and in the vertical (cross-section is teardrop-shaped. The strength of this protective device is therefore greatest in the horizontal plane.
