Abstract
Description
Die Erfindung betrifft ein Fahrzeug mit einer Einzelradaufhängungen für lenkbare Vorderräder aufweisenden Vorderwagenstruktur, wobei im Fall eines teilüberdeckten Frontalaufpralls ein Vorderrad derart Eingeschlagen wird, dass dessen Radialebene die Längsmittellinie des Fahrzeugs vor demselben schneidet.The invention relates to a vehicle with a front suspensory structure having steerable front wheels, wherein in the case of a partially overlapped frontal impact, a front wheel is struck such that its radial plane intersects the longitudinal centerline of the vehicle in front of it.
Unter einem teilüberdeckten Frontalaufprall wird ein Frontalaufprall mit einem seitlich versetzten Kollisionspartner verstanden, so dass nur an einem vorderen seitlichen Teil der Frontpartie des Fahrzeugs eine Kollisionszone entsteht. Beispielhaft ist ein solcher Lastfall mit geringer Überdeckung des Fahrzeugs anhand eines dezentralen Pfahlaufpralls gemäß
Diese
Zur Vermeidung dieser Nachteile schlägt die gattungsbildende
In ähnlicher Weise ist auch aus der
Solche für das Einschlagen des Vorderrades eines Fahrzeugs vorgeschlagene Kinematiken erfordern einen hohen Bauteilaufwand, der die Herstellungskosten maßgeblich erhöht.Such proposed for driving the front wheel of a vehicle kinematics require a high component cost, which significantly increases the cost of manufacture.
Aufgabe der Erfindung ist es ein Fahrzeug der eingangs genannten Art anzugeben, bei welchen mit konstruktiv einfachen Mitteln ein Einschlagen eines kollisionsseitigen Vorderrades im Falle eines versetzten Frontalaufpralls erreicht wird.The object of the invention is to provide a vehicle of the type mentioned, in which a structurally simple means a collision of a collision-side front wheel is achieved in the event of an offset frontal collision.
Diese Aufgabe wird gelöst durch ein Fahrzeug mit den Merkmalen des Patentanspruchs 1.This object is achieved by a vehicle having the features of patent claim 1.
Eine solches Fahrzeug mit einer Einzelradaufhängungen für lenkbare Vorderräder aufweisenden Vorderwagenstruktur, bei welchem im Fall eines teilüberdeckten Frontalaufpralls ein kollisionsseitiges Vorderrad derart eingeschlagen wird, dass dessen Radialebene die Längsmittellinie des Fahrzeugs vor demselben schneidet, zeichnet sich erfindungsgemäß dadurch aus, dass wenigstens ein Lenker von mehreren Lenkern der Einzelradaufhängung des kollisionsseitigen Vorderrades mit einer Trenneinrichtung zum Trennen von dessen Anbindung an das Fahrwerk des Fahrzeugs im Falle des teilüberdeckten Frontalaufpralls ausgebildet ist, und im Fall des teilüberdeckten Frontalaufpralls wenigstens ein verbleibender Lenker der Einzelradaufhängung des kollisionsseitigen Vorderades durch dessen Deformation das Einschlagen dieses Vorderrades zulassend ausgebildet ist.According to the invention, such a vehicle with a front wheel structure having steerable front wheels has a front side collision-side front wheel cut in such a way that its radial plane intersects the longitudinal center line of the vehicle in front of it, characterized in that at least one arm of several links the independent suspension of the collision-side front wheel is formed with a separating device for separating its connection to the chassis of the vehicle in the case of partially overlapped frontal impact, and in the case of partially overlapped frontal impact at least one remaining link of the independent suspension of the collision side front wheel by the deformation permitting the turning of this front wheel is.
Durch das teilweise Lösen des Vorderrades von dem Fahrwerk des Fahrzeugs bewirkt der durch den Frontalaufprall erzeugte Krafteintrag das Einschlagen bzw. das Eindrehen des Vorderrades durch eine Deformation der verbleibenden an dem Fahrwerk noch angebundenen Lenker. Hierzu sind keine zusätzlichen Bauteile wie im Stand der Technik erforderlich, sondern es genügt eine entsprechende Ausbildung wenigstens eines Lenkers mit Trenneinrichtungen, die kostengünstig realisiert werden können.As a result of the partial release of the front wheel from the chassis of the vehicle, the force input generated by the frontal impact causes the turning in of the front wheel by a deformation of the remaining link still connected to the chassis. For this purpose, no additional components as required in the prior art, but it is sufficient to form a corresponding training at least a handlebar with separation devices that can be realized inexpensively.
Mit einer solchen erfindungsgemäßen Einzelradaufhängung wird im Falle eines versetzten und Frontalaufpralls eine Kinematik des kollisionsseitigen Vorderrades herbeigeführt, die zu einem Abgleiten dieses Vorderrades an der dahinterliegenden Struktur, wie dem Radraum und der A-Säule der Fahrzeugkarosserie führt und damit eine Entlastung der Fahrgastzelle ermöglicht wird.With such an inventive independent suspension is in the case of an offset and Frontal impact brought about a kinematics of the collision-side front wheel, which leads to a slipping of this front wheel on the underlying structure, such as the wheel space and the A-pillar of the vehicle body and thus a discharge of the passenger compartment is made possible.
In einer vorteilhaften Ausgestaltung der Erfindung umfasst die Einzelradaufhängung wenigstens einen oder mehrere fahrzeugvorderseitige Lenker und wenigstens einen fahrzeugrückseitigen Lenker, wobei der wenigstens eine fahrzeugvorderseitige Lenker oder die fahrzeugvorderseitigen Lenker mit einer Trenneinrichtung ausgebildet ist oder sind. Damit können auch Radaufhängungen mit unterschiedlichen geometrischen Ausgestaltungen erfindungsgemäß ausgebildet werden.In an advantageous embodiment of the invention, the independent suspension comprises at least one or more vehicle front-side links and at least one rear link, wherein the at least one vehicle front-side link or the vehicle front-side link is or are formed with a separator. Thus, wheel suspensions with different geometrical configurations can also be designed according to the invention.
Besonders vorteilhaft ist es gemäß einer Ausgestaltung der Erfindung, wenn die Trenneinrichtung als Sollbruchstelle ausgebildet ist, derart dass im Fall des teilüberdeckten Frontalaufpralls die Anbindung des die Trenneinrichtung aufweisenden Lenkers an das Fahrwerk gelöst wird. Dabei ist die Sollbruchstelle an die bei einem versetzten Frontalaufprall auftretenden Belastungen angepasst, so dass im normalen Betrieb des Fahrzeugs die Stabilität der Radaufhängung gewährleistet ist.It is particularly advantageous according to an embodiment of the invention, when the separating device is designed as a predetermined breaking point, so that in the case of partially covered frontal impact, the connection of the separator having the handlebar is solved to the chassis. In this case, the predetermined breaking point is adapted to the loads occurring in an offset frontal impact, so that the stability of the suspension is ensured during normal operation of the vehicle.
Alternativ oder zusätzlich kann gemäß einer weiteren Ausgestaltung der Erfindung der wenigstens eine Lenker mit einer pyrotechnisch ausgebildeten Trenneinrichtung, vorzugsweise mit einer die Anbindung an das Fahrwerk realisierenden Sprengschraube ausgebildet werden. Eine solche pyrotechnisch ausgebildete Trenneinrichtung kann elektrisch über ein Steuergerät ausgelöst werden, welchem die Sensorsignale von Crashsensoren zur Erkennung eines Frontalaufpralls zugeführt werden.Alternatively or additionally, according to a further embodiment of the invention, the at least one link with a pyrotechnically designed separating device, preferably with a connection to the landing gear realized explosive screw can be formed. Such a pyrotechnically designed separating device can be triggered electrically via a control unit, to which the sensor signals of crash sensors are supplied for detecting a frontal impact.
