Description

Abfederung, insbesondere für Kraftfahrzeuge Die Aufgabe, die durch die vorliegende Erfindung gelöst werden soll, in abgefederten Fahrzeugen künstliche Ruhepunkte bzw. Schwingungsknotenpunkte für die zu transportierende Last zu schaffen, stimmt mit derjenigen überein, die sich das Patent .:1.69 o96 stellte. Die Schwierigkeiten, die der Lösung dieser Aufgabe entgegenstehen, beruhen u. a. darauf, daß sich in einem Fahrzeug nebeneinander und hintereinander ganz verschiedenartige Schwingungen mit verschiedenartig gelagerten Knotenpunkten ausbilden und daß unter Umständen auch eine Schwingungsart in die andre übergeht, wobei die Oszillationsachsen bzw. die Schwingungsknoten stetig oder sprunghaft ihre Lage verändern.Cushioning, especially for motor vehicles The task carried out by The present invention aims to be achieved in artificial sprung vehicles To create points of rest or vibration nodes for the load to be transported, agrees with the one that the patent.: 1.69 o96 posed. Difficulties, which stand in the way of solving this problem are, inter alia, that in a vehicle side by side and one behind the other very different types of vibrations train with differently mounted nodes and that under certain circumstances one type of oscillation also merges into the other, whereby the oscillation axes resp. the vibration nodes change their position steadily or suddenly.

Auf Grund von Untersuchungen und Versuchen am praktischen Fahrzeug hat sich die neue Erkenntnis ergeben, daß man zu stabilen Verhältnissen gelangt, wenn man zwei Schwingungssysteme oder Systemgruppen schafft, die senkrecht gegeneinander bewegt werden, und gleichzeitig dafür sorgt, daß die Charakteristik der in beiden Systemen ver-@vendeten elastischen Mittel annähernd gleich ist.Based on examinations and tests on the practical vehicle has the new knowledge emerged that one arrives at stable conditions, if you create two oscillation systems or system groups that are perpendicular to each other be moved, and at the same time ensures that the characteristic of both Systems used elastic means is approximately the same.

Wenn das Rad eines Fahrzeuges eine Unebenheit überfährt und dementsprechend einen Impuls auf den Fahrzeugrahmen ausübt, so folgt der Fahrzeugrahmen, der mit der Fahrzeugfeder ein schwingendes System bildet, in einer gewissen Nacheilung diesem Impulse.When the wheel of a vehicle drives over a bump and accordingly exerts an impulse on the vehicle frame, the vehicle frame follows the the vehicle spring forms an oscillating system, lagging behind it to a certain extent Impulses.

Nun stellt, ebenso wie der Fahrzeugrahmen zusammen mit den Fahrzeugfedern, das Sitzpolster mit der auf ihm befindlichen Person ein schwingendes System dar. Wenn beide Systeme mit senkrecht gegeneinander gerichteten Bewegungsimpulsen erregt werden und ihre elastischen Mittel, d. h. die Fahrzeugfeder und'-die Federn des Sitzpolsters, die gleiche Charakteristik aufweisen, dann müssen sich auch die Massen der beiden Systeme, d. h. der Fahrzeugrahmen und die auf dem Sitzpolster sitzende Person oder eine durch eine besondere Federung unterstützte Last, senkrecht gegeneinander bewegen. Ganz besonders günstige Verhältnisse werden geschaffen, wenn genannte elastische Mittel unharmonisch bzw. pseudoharmonisch schwingen. Die Erregerimpulse müssen nur so geleitet werden, daß jeder Impuls, der den Fahrzeugrahmen um einen gewissen Weg senkt, die das Sitzpolster belastende Masse tun denselben Weghebt, eine Bedingung, die konstruktiv mit bekannten Mitteln leicht lösbar ist. Es ist hierbei gleichgültig, ob man sich zum Heben und Senken des Fahrzeugrahmens und des die Last tragenden Rahmens Seilzüge, Zahnstangen, Luftzylinder, Hebelmechanismen u. dg1. bekannten Mittel bedient.Now, just like the vehicle frame together with the vehicle springs, the seat cushion with the person on it represents a vibrating system. When both systems are excited with movement impulses directed at right angles to one another and their elastic means, d. H. the vehicle spring and'-the springs of the Seat cushions that have the same characteristics, then the masses must also of the two systems, d. H. the vehicle frame and the one sitting on the seat cushion Person or a load supported by a special suspension, perpendicular to each other move. Particularly favorable conditions are created when said elastic ones Vibrate medium inharmonic or pseudo-harmonic. The excitation impulses just have to be directed so that every pulse that moves the vehicle frame by a certain distance lowers, which lifts the mass of the seat upholstery doing the same, a condition which can easily be solved structurally with known means. It does not matter here whether you want to raise and lower the vehicle frame and the load-bearing Frame Cable pulls, racks, air cylinders, lever mechanisms, etc. dg1. known means.
