Abstract

Die Erfindung betrifft einen mechanischen Energie-Transformator, wobei die Bewegungsenergie F eines Körpers durch Umwandlung in Rotationsenergie ein sehr kurzfristiges Abbremsen ohne Beschädigung des Körpers bzw. Verletzung der Insassen zulässt.The invention relates to a mechanical energy transformer, wherein the kinetic energy F of a body by conversion into rotational energy allows a very short-term deceleration without damaging the body or injury to the occupants.

Description

Wird ein Körper von A nach B mit einer Geschwindigkeit V = X bewegt und auf V = 0 abgebremst, wird durch die Weglänge S die Größe der auftretenden Fliehkraft (Bewegungsenergie) F bestimmt: Je kürzer der Weg ist, desto größer wird die Fliehkraft.Becomes a body moved from A to B at a speed V = X and at V = 0 decelerated, the path length S is the size of the occurring Centrifugal force (kinetic energy) F determines: The shorter the path, the bigger it gets the centrifugal force.

Beispiel: Mit Knautschzonen oder Airbags in Kraftfahrzeugen werden die Fliehkräfte gemindert, indem der Weg bis zum Aufprall (V = 0) verlängert wird. Dieser Weg reicht aber bei höheren Geschwindigkeiten nicht aus, um bei einem Aufprall Verletzungen der Passagiere zu vermeiden. Die Erfindung nutzt die beschriebene Tatsache, dass die Größe der Fliehkraft bei einem Abbremsvorgang nur von der zur Verfügung stehenden Weglänge abhängt, um einen mit der Geschwindigkeit V = X bewegten Körper bis auf V = 0 abzubremsen, wobei der Weg nicht linear verlaufen muss.Example: With crumple zones or airbags in motor vehicles, the centrifugal forces are reduced by the way up to the impact (V = 0) is extended. This path is enough but at higher Speeds do not turn out to be injured in a collision to avoid the passengers. The invention uses the described Fact that the size of centrifugal force during a braking process depends only on the available path length to decelerate a body moving at speed V = X to V = 0, where the path does not have to be linear.

Die Lösung dieser Aufgabe wird erreicht, indem (wie z.B. in 1 dargestellt) die Fliehkraft (Bewegungsenergie) F eines Körpers (z.B. eines Kraftfahrzeugs) über einen Mechanismus (wie z.B. Zahnstange 1 auf Übersetzungsgetriebe 2) in eine Rotationsbewegung umgesetzt und auf eine Schwungmasse 3 übertragen wird. Die Bewegungsenergie kann auf verschiedene Weise genutzt werden: Wie z.B. in 2 dargestellt, wird durch eine Abbremsvorrichtung 4 Reibungswärme erzeugt.The solution to this problem is achieved by (as in 1 shown) the centrifugal force (kinetic energy) F of a body (eg a motor vehicle) via a mechanism (such as rack 1 on transmission gear 2 ) converted into a rotational movement and a flywheel 3 is transmitted. The kinetic energy can be used in different ways: eg in 2 is represented by a braking device 4 Generates frictional heat.

Bei einer nutzbaren Zahnstangenlänge von z.B. 20 cm und einer Getriebeübersetzung von 1:50 wird ein physikalischer Bremsweg von 20 cm × 50 = 1000 cm bzw. 10 m erzeugt. Hier tritt die gleiche Fliehkraft wie bei einem linearen Bremsweg von 10 m auf.at a usable rack length from e.g. 20 cm and a gear ratio of 1:50 is one physical braking distance of 20 cm × 50 = 1000 cm or 10 m generated. Here occurs the same centrifugal force as with a linear braking distance from 10 m up.

Mit diesem Energie-Transformator wird ein mit z.B. 60 km/h auf einen festen Gegenstand aufprallendes Kraftfahrzeug nicht beschädigt und der Fahrer bleibt auch ohne Sicherungsgurt unverletzt. Voraussetzung ist, dass durch eine entsprechende Dimensionierung der Mechanik und/oder zusätzliche Dämpfungsmaßnahmen 5 (wie in 1 – 3 skizziert) eine Überlastung einzelner Bauteile vermieden wird.With this energy transformer, a motor vehicle colliding with eg 60 km / h on a solid object is not damaged and the driver remains unhurt even without safety belt. The condition is that by an appropriate dimensioning of the mechanics and / or additional damping measures 5 (as in 1 - 3 sketched) an overload of individual components is avoided.

Ein gleicher Effekt wird erreicht (wie in 3 gezeigt), wenn die Fliehkraft F über einen Hydraulikkolben 6 mittels Hydraulikflüssigkeit 7 durch eine Öffnung in der Zylinderwand 8, vorzugsweise in einem Winkel von 90° zur Kolbenlaufrichtung angeordnet, transformiert wird. Das Größenverhältnis der Fläche des Kolbens 6 zur Fläche der Öffnung in der Zylinderwand 8 bestimmt das erforderliche Übersetzungsverhältnis.A similar effect is achieved (as in 3 shown) when the centrifugal force F via a hydraulic piston 6 by means of hydraulic fluid 7 through an opening in the cylinder wall 8th , preferably arranged at an angle of 90 ° to the piston running direction, is transformed. The size ratio of the area of the piston 6 to the surface of the opening in the cylinder wall 8th determines the required gear ratio.
