Abstract
Description
Die Erfindung betrifft ein Verfahren zur Beeinflussung einer Fahrzeugkennlinie gemäß Oberbegriff des Patentanspruchs 1 sowie eine Tragstruktur für einen solchen Kraftwagen und eine Radfelge.The The invention relates to a method for influencing a vehicle characteristic according to the generic term of claim 1 and a support structure for such a motor vehicle and a wheel rim.
Im Kraftfahrzeugbau ist es allgemeines Ziel, bei einem Crash die Verzögerungswerte auf den Fahrzeuginsassen so gering wie möglich zu halten um Verletzungen zu verhindern oder zu minimieren. Dies wird in der Regel durch eine deformierbare Knautschzone im Vorbau eines Kraftwagens erreicht, wobei in Folge einer crashbedingten Verformung der Knautschzone die im Vorderwagen angeordneten Räder in Richtung der Sicherheitsfahrgastzelle bewegt werden.in the Automotive engineering is the general goal in a crash, the delay values to keep the occupants as low as possible to prevent injury to prevent or minimize. This is usually done by a reaches deformable crumple zone in the stem of a motor vehicle, wherein as a result of a crash-induced deformation of the crumple zone in the Front wheel arranged wheels be moved in the direction of the safety passenger cell.

Es besteht die Aufgabe, ein Verfahren zur Beeinflussung einer Fahrzeugkennlinie sowie eine Tragstruktur und eine Radfelge zu schaffen, bei der auch bei großem Felgendurchmesser ein sprunghafter Anstieg der Verzögerungswerte vermieden wird.It the task is a method for influencing a vehicle characteristic as well as to create a supporting structure and a wheel rim, in which too at large Rim diameter a sudden increase in the deceleration values is avoided.
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 sowie des Anspruchs 4 und des Anspruchs 5 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The Task is according to the invention with the features of claim 1 and of claim 4 and claim 5. advantageous Embodiments emerge from the subclaims.
Kraftwagen, die mit Rändern mit großem Felgendurchmesser ausgestattet sind, bedingen eine relativ geringe Deformationslänge der Knautschzone im Vorderwagen, so dass sowohl beim Frontalaufprall als auch beim Schrägaufprall die steifen Radfelgen relativ schnell mit der Barriere oder dem Unfallgegner in Kontakt kommen. Mit einem gezielten Versagen der Radfelge im Falle eines Aufpralls wird eine Reduzierung des wirksamen Felgendurchmessers bewirkt, so dass zusätzlicher Deformationsweg innerhalb der Knautschzone zur Verfügung gestellt wird. Dies hat sowohl Vorteile bei der Energieabsorption für den Frontalaufprall als auch für den Schrägaufprall. Hinzu kommt beim Schrägaufprall, dass der Forderwagen an der Barriere beziehungsweise an dem Unfallgegner abgleiten kann, so dass die Verzögerungswerte weiter reduziert werden. Der Kraftwagen wird sozusagen aus seiner linearen Bewegung entsprechend dem Impuls abgedreht. Insbesondere bei niedrigem Fahrzeugdach mit relativ schräg geneigter A-Säule, kann ein Touchieren der Windschutzscheibe verhindert werden.Automobile, those with edges with big Rim diameter are equipped, require a relatively small deformation length the crumple zone in the front, so that both the frontal impact as well as the oblique impact the stiff wheel rims relatively fast with the barrier or the Accident opponents come into contact. With a deliberate failure of Wheel rim in case of impact will be a reduction of the effective Rim diameter causes, so that additional deformation path within the crumple zone available is provided. This has both advantages in energy absorption for the Frontal impact as well the oblique impact. Added to this is the oblique impact, that the Forderwagen at the barrier or at the accident opponent can slide off, so that the delay values be further reduced. The car is sort of out of his turned off linear motion according to the impulse. Especially at low vehicle roof with a relatively inclined A-pillar, can Touching the windscreen can be prevented.
Bei einer entsprechend ausgestalteten Tragstruktur ist die Radfelge durch ihr Versagen bei der Deformation der Knautschzone sozusagen nicht mehr im Weg, so dass Energie durch die Knautschzone aufgenommen werden kann.at a correspondingly designed support structure is the wheel rim by their failure in the deformation of the crumple zone, so to speak no more in the way, allowing energy to be absorbed through the crumple zone can be.
Vorzugsweise ist die Radfelge so ausgebildet, dass sie bei radial auf die Radfelge wirkende Radkräfte versagt. Bei normalen Betriebskräften versagt die Radfelge selbstverständlich nicht.Preferably The wheel rim is designed so that it is radial on the wheel rim acting wheel forces failed. At normal operating forces Of course, the wheel rim fails Not.
Dies kann erreicht werden, wenn die Mittel zum gezielten Versagen umfangsseitig in der Felgenkontur der Radfelge radial ausgerichtet sind.This can be achieved if the means of targeted failure circumferentially are radially aligned in the rim contour of the wheel rim.
In einer bevorzugten Ausgestaltungsform sind die Mittel zum gezielten Versagen als Crashbohrungen ausgebildet, die zwischen den Radspeichen in der Felgenkontur angeordnet sind.In In a preferred embodiment, the means for targeted Failure trained as crash bores, in between the wheel spokes in the rim contour are arranged.
Denkbar als Mittel zum gezielten Versagen sind auch radiale Wandstärkenwechsel. Das heißt, die Felgenkontur kann in ihrer Wandstärke Differenzen aufweisen, so dass bei radialer Belastung die dünnen Wandstärken zuerst versagen und somit den Felgendurchmesser reduzieren.Conceivable as a means of targeted failure are also radial wall thickness change. That is, the Rim contour may have differences in wall thickness, so that at radial load, the thin wall thicknesses fail first and thus reduce the rim diameter.
Möglich sind auch als Mittel zum gezielten Versagen Speichenschwächungen, wobei diese nicht bei Scherkräften, das heißt also im normalen Betriebszustand, versagen.Possible are also as a means of deliberate failure spoke weakenings, these are not shear forces, this means So in normal operating condition, fail.
Weitere bevorzugte Ausgestaltungen sind anhand der Zeichnung näher erläutert.Further preferred embodiments are explained in more detail with reference to the drawing.
Dabei zeigen:there demonstrate:
Die Ausgestaltung der deformierbaren Tragstruktur spielt für die Beeinflussung der Fahrzeugkennlinie nur insoweit eine Rolle, als dass der Zeitpunkt des Versagens der Radfelge darauf abgestimmt werden muss.The Design of the deformable support structure plays for the influence the vehicle characteristic only to the extent that the time the failure of the wheel rim must be tuned to it.

Es versteht sich von selbst, dass die Mittel zum gezielten Versagen nur dann ansprechen, wenn entsprechend hohe Kräfte auf die Radfelge wirken. Bei normalen, im Betriebszustand wirkenden Kräften, beispielsweise beim Abrollen oder beim Befahren einer Bordsteinkante, versagt die Felge nicht.It It goes without saying that the means of targeted failure only respond if correspondingly high forces act on the wheel rim. at normal, operating forces, such as unwinding or when driving on a curb, the rim does not fail.
