Description
In weiteren Schreiben "Ausfahrstoßstange" genannt.In other letters called "exit bumper".
Die täglich passierenden Auffahr- und Aufschubunfälle fordern Leben, Gesundheit und verursachen große Sachschäden.The daily rear-end and postponement accidents demand Life, health and cause great damage to property.
Die hier beschriebene Erfindung "Ausfahrstoßstange" mindert, oder hebt bei leichten Kollisionen diese Unfälle ganz auf.The "extension bumper" invention described here reduces or completely eliminates these accidents in the event of minor collisions.
Die "Ausfahrstoßstange" besteht aus der Profilstahl-Montage schiene 1, der eigentlichen "Ausfahrstoßstange" 2, die Flanschen gegeneinander gerichtet Fig. 2, so daß ein Hohlraum entsteht.The "exit bumper" consists of the section steel mounting rail 1 , the actual "exit bumper" 2 , the flanges directed towards each other Fig. 2, so that a cavity is formed.
In diesem Hohlraum sind 2 Doppel-Gelenkarme 3-4, hydraulische Öl bremse 5, Zweifach-Verriegelung 6, evtl. Einzugsmechanik 18, mit Wickelbändern 8, Stoßdämpfer 19, - werden je nach Typ, außerhalb montiert -, Diametralgestänge 12, und Schenkelfedern 17, einge baut.In this cavity are 2 double articulated arms 3-4 , hydraulic oil brake 5 , double lock 6 , possibly retraction mechanism 18 , with winding tapes 8 , shock absorbers 19 , - depending on the type, are mounted outside -, diametral linkage 12 , and leg springs 17 , built-in.
Dadurch entsteht eine Kompakteinheit einfachster Konstruktion, billigster Herstellungskosten; da keine Sondermaschinen und Werk zeuge erforderlich sind, bei optimaler Wirkung. Anpassungs möglichkeiten vom Kleinwagen bis LKWs durch entsprechende Ver größerung oder auch 2 Einheiten sind möglich.This creates a compact unit of the simplest design, cheapest manufacturing cost; since no special machines and factory are necessary, with optimal effect. Adjustment Possibilities from small cars to trucks through appropriate ver Enlargement or 2 units are possible.
Durch die Konstruktionsart "Kompakteinheit" ist nachträglicher Anbau an jedes Fahrzeug möglich. Auch die Gestaltung einer Blende auf die Ausfahrstoßstange 2, zum Wagentyp passend, ist problemlos. Die Ausfahrarme 3-4, bilden über die 3 bzw. 6 Schar niere 9-10-11, ausschwenkbare Kniehebelarme und verbinden Montageschiene 1, mit Ausfahrstoßstange 2. Thanks to the "compact unit" design, it can be retrofitted to any vehicle. The design of a cover on the extension bumper 2 to match the car type is also easy. The extension arms 3-4 , form kidney 9-10-11 , can be swung out over the 3 or 6 coulter arms and connect the mounting rail 1 with the extension bumper 2 .
Die Ausfahrstoßstange 2, wird mittels der Einzugsmechanik 18-7, über die Wickelbänder 8, eingefahren. Dadurch werden die Schenkelfedern 17 vorgespannt und durch die Verriegelung 6 festgehalten. Diese Verriegelung ist über Bautenzug 15, Fig. 2, mit dem Bremspedal verbunden und wird nur bei Vollbremsung ausgelöst. Die Auslösung kann auch über Gestänge, elektrisch, hydraulisch ect. erfolgen.The extension bumper 2 is retracted by means of the retraction mechanism 18-7 , via the winding tapes 8 . As a result, the leg springs 17 are preloaded and held in place by the lock 6 . This lock is connected to the brake pedal via component train 15 , FIG. 2, and is only triggered when the brakes are applied fully. The triggering can also be done via linkage, electrical, hydraulic ect. respectively.
Die Einzugsmechanik wird von einem, von der Batterie gespeisten, stabförmigen Getriebemotor mit Freilauf 18, über Wickelwelle 7, angetrieben. Eingeschaltet vom Fahrer, ausgeschaltet über Endschalter.The retraction mechanism is driven by a rod-shaped gear motor with free wheel 18 , which is powered by the battery, via winding shaft 7 . Switched on by the driver, switched off via limit switch.
Nach einer Vollbremsung fährt die Ausfahrstoßstange 2, in einem Bruchteil einer Sekunde von Ruhestellung a, nach Einsatz stellung b, aus. Kommt es zu einer Kollision, wird der Rückstoß von der Ausfahrstoßstange 2, über die 2 Doppelgelenkarme 3-4, der hydraulischen Ölbremse 5, der Stoßdämpfer 19, und den Schenkel federn 17, optimal abgebremst und in die Ausgangsstellung a, zurückgedrängt. Durch die Dämpfungskräfte wird der Frontalcrash und damit die Knautschzone erheblich verkürzt oder ganz aufge hoben.After an emergency stop, the extension bumper 2 extends from the rest position a to the use position b in a fraction of a second. If there is a collision, the recoil from the extension bumper 2 , the 2 double articulated arms 3-4 , the hydraulic oil brake 5 , the shock absorber 19 , and the leg springs 17 , optimally braked and pushed back into the starting position a. The frontal crash and thus the crumple zone is considerably shortened or completely eliminated by the damping forces.
