Description
Das Patent 1 001 601 beschreibt eine Radabfederung, insbesondere für Fahrzeuge, mit Radaufhängung an einem am Fahrzeugkörper gelagerten doppelarmigen Schwenkhebel, an dessen einem Arm die Radachse angeordnet und dessen anderer Arm durch Federkraft abgestützt ist, wobei der Schwenkhebel mit dem daran angeordneten Rad als ein im wesentlichen gewichtsausgeglichener Waagebalken ausgebildet ist, an dem sowohl ein Gegengewicht als auch die Kraft der Feder mit größerem Abstand vom Drehpunkt angreift als das Gewicht des Rades am gegenüberliegenden Arm. Der Schwenkhebel bildet einen auf seinem Drehzapfen abgestützten Biegeträger, an dessen einem Arm, dem Kraftarm, die Federkraft und an dessen anderem Arm, dem Radarm, der Raddruck angreift. Der Querschnitt der beiden Arme ist wie üblich so bemessen, daß Überbeanspruchungen durch auftretende Stöße aufgenommen werden können. Trotzdem biegt er unter Last durch, und zwar der Lastarm durch seine größere Länge mehr als der kurze Radarm.The patent 1 001 601 describes a wheel suspension, in particular for vehicles, with a wheel suspension on a double-armed pivot lever mounted on the vehicle body, on one arm of which the Arranged wheel axle and the other arm is supported by spring force, the pivot lever formed with the wheel arranged thereon as an essentially weight-balanced balance beam is on which both a counterweight and the force of the spring at a greater distance from the pivot point attacks than the weight of the wheel on the opposite arm. The pivot lever forms a on its pivot supported bending beam, on one arm, the power arm, the spring force and on the other arm, the wheel arm, the wheel pressure is applied. The cross section of the two arms is like Usually dimensioned in such a way that overstressing caused by impacts can be absorbed. Nevertheless it bends under load, namely the load arm more than the short wheel arm due to its greater length.
Diese Durchbiegung unter Last ist bei derartigen Radabfederungen insofern von entscheidender Bedeutung, als sie Einfluß nimmt sowohl auf die auftretende Stoßwirkung beim Überfahren von Hindernissen als auch auf die dämpfende Wirkung eines dem Rad zügeordneten Gegengewichtes bei einem durch den Stoß in Schwingung versetzten Hebel. Bei starrer Ausbildung von Radarm und Kraftarm geht bei Ermittlung der Stoßwirku'ng die gesamte Masse von Rad, Hebel und Gegengewicht in die Rechnung ein, weil sie durch die starre Ausbildung durch den Stoß gleichzeitig beschleunigt werden muß. Man erhält also als Wert ein Maximum. Bei elastischer Ausbildung der beiden Arme erreicht man dagegen ein Minimum an Schlagwirkung, der Dämpfungseffekt des Gegengewichtes geht dabei jedoch nahezu vollkommen verloren. Es kommt also darauf an, zwischen diesen beiden Extremen den günstigsten Mittelwert durch entsprechende Ausbildung der beiden Hebelarme zu finden.This deflection under load is of decisive importance for such wheel suspension systems, as it influences both the impact effect when driving over obstacles as also on the damping effect of a counterweight assigned to the wheel in the event of a shock in Oscillating lever. In the case of a rigid design of the wheel arm and power arm, determination is possible of the shock effect, the total mass of the wheel, lever and counterweight is included in the calculation, because it is through the rigid training must be accelerated by the shock at the same time. So you get a value as a value Maximum. In contrast, if the two arms are made elastic, a minimum of impact is achieved. the damping effect of the counterweight is almost completely lost. It So it depends on finding the most favorable mean between these two extremes by corresponding Find training of the two lever arms.
Da an beide Arme des Schwenkhebels unterschiedliehe Anforderungen gestellt werden, wird gemäß der Erfindung der Radarm möglichst starr, der Kraftarm dagegen federnd ausgebildet. Besondere Vorteile bieten sich, wenn man den Kraftarm vom Radarm trennt. Um Biege- und Verdrehkräfte mit geringster Formänderung aufnehmen zu können, wird der Radarm aus einem wenig federnden Werkstoff hergestellt, wogegen der Kraftarm, an dem die Federkraft angreift, als federnder Stab ausgebildet wird, der in Taschen des Radarmes eingreift. Die Durchbiegung des Kraftarmes unter statischer Last wird mögl'ichst klein gewählt ; Federstabquerschnitt und Gegengewicht werden so bemessen, daß sie auftretenden Radschwingungen entgegenwi rken.Since different requirements are placed on both arms of the pivot lever, according to the Invention of the wheel arm as rigid as possible, while the power arm is designed to be resilient. Offer special advantages when you separate the power arm from the wheel arm. About bending and twisting forces with the slightest change in shape To be able to accommodate, the wheel arm is made of a less resilient material, whereas the force arm, on which the spring force acts, is designed as a resilient rod, which is in pockets of the The radar intervenes. The deflection of the force arm under static load is chosen to be as small as possible ; The cross-section of the spring rod and the counterweight are dimensioned in such a way that they prevent wheel vibrations counteract.

Im weiteren Ausbau der Erfindung wird ein wenig federnder Kraftarm verwendet und elastisch am Radarm angeordnet. Als elastisches Glied zwischen beiden verwendet man vorteilhaft federnde Stoffe mit starker Eigendämpfung, z. B. Gummi.In the further development of the invention, a somewhat resilient force arm is used and arranged elastically on the wheel arm. As an elastic link between the two one uses advantageously resilient materials with strong self-damping, z. B. rubber.
Für die statische Belastung des Federaggregates sind die angeführten Maßnahmen ohne nennenswerte Bedeutung. Entsprechend der unterschiedlichen Belastung stellt sich der Waagebalken jeweils in Gleichgewichtsstellung. Dagegen tritt bei zusätzlicher Belastung, z. B. durch Stoß beim Überfahren eines Hindernisses, die angestrebte Verzögerung im Bewegungsablauf zwischen Radarm und Kraftarm ein.For the static load on the spring assembly, the measures listed are not worth mentioning Meaning. Depending on the different loads, the balance beam is in a position of equilibrium. On the other hand occurs with additional load, z. B. by impact when driving over a Obstacle, the desired delay in the movement sequence between the wheel arm and the power arm.
