Abstract
Es wird eine Fronthaubenanordnung für Fahrzeuge vorgeschlagen, die eine Fronthaube (11) umfasst, welche mittels mindestens eines Eingelenkscharniers (13) schwenkbar gelagert ist, wobei die Fronthaube (11) mittels eines Aktuators aus einer Normalposition in eine angehobene Schutzposition überführbar ist, und wobei der Aktuator (35) und das Eingelenkscharnier (13) miteinander gekoppelt sind. DOLLAR A Die Fronthaubenanordnung zeichnet sich dadurch aus, dass der Aktuator (35) und das Eingelenkscharnier (13) mittels einer Hebelmechanik (21) miteinander gekoppelt sind und dass der Aktuator (35) gegenüber dem Eingelenkscharnier (13) in Fahrzeuglängsrichtung versetzt angeordnet ist.It is proposed a front bonnet assembly for vehicles, comprising a front hood (11) which is pivotally mounted by means of at least one Einelenkscharniers (13), wherein the front hood (11) is convertible by means of an actuator from a normal position to a raised protective position, and wherein the Actuator (35) and the Einelenkscharnier (13) are coupled together. DOLLAR A The bonnet assembly is characterized in that the actuator (35) and the Einelenkscharnier (13) by means of a lever mechanism (21) are coupled together and that the actuator (35) relative to the Einelenkscharnier (13) is arranged offset in the vehicle longitudinal direction.
Description
Die Erfindung betrifft eine Fronthaubenanordnung für Fahrzeuge, insbesondere Kraftfahrzeuge, gemäß Oberbegriff des Anspruchs 1.The The invention relates to a bonnet arrangement for vehicles, in particular motor vehicles, according to the generic term of claim 1.
Aus
der
Es ist Aufgabe der Erfindung, eine Fronthaubenanordnung der eingangs genannte Art zu schaffen, die einen einfachen und kostengünstigen Aufbau aufweist und die Möglichkeit einer praktisch frei wählbaren Positionierung des Aktuators relativ gegenüber dem Eingelenkscharnier bietet.It Object of the invention, a bonnet assembly of the above to create said type, which is a simple and cost-effective Structure has and possibility a practically freely selectable Positioning of the actuator relative to the single pivot hinge offers.
Zur Lösung der Aufgabe wird eine Fronthaubenanordnung mit den Merkmalen des Anspruchs 1 vorgeschlagen. Diese zeichnet sich dadurch aus, dass der Aktuator und das Eingelenkscharnier mittels einer Hebelmechanik miteinander gekoppelt sind und dass der Aktuator gegenüber dem Eingelenkscharnier in Fahrzeuglängsrichtung versetzt angeordnet ist. Diese Ausgestaltung der Fronthaubenanordnung bietet die Möglichkeit, den Aktuator deutlich entfernt von der A-Säule beziehungsweise dem A-Säulenfuß und gegebenenfalls im Übergangsbereich zwischen A-Säule beziehungsweise A-Säulenfuß und einem oberen Längsträger des Karosserierohbaus anzuordnen, damit weder die A-Säule geschwächt, noch der obere Längsträger in seinem Faltungsbereich im Crashfall behindert wird.to solution The object is a bonnet assembly with the features of Proposed claim 1. This is characterized by the fact that the actuator and the Einelenkscharnier means of a lever mechanism coupled to each other and that the actuator against the Single-joint hinge in the vehicle longitudinal direction is arranged offset. This embodiment of the front hood arrangement offers the possibility, the actuator clearly away from the A-pillar or the A-pillar and optionally in the transition area between A-pillar or A-pillar base and an upper one Side member of the To arrange bodywork so that neither the A-pillar weakened, nor the upper side member in his Convolution area is impeded in the event of a crash.
Besonders bevorzugt wird ein Ausführungsbeispiel der Fronthaubenanordnung, bei der die Hebelmechanik so ausgebildet ist, dass das Eingelenkscharnier entlang einer Bewegungsbahn verlagerbar ist, die in vertikaler Richtung (z-Richtung), also senkrecht oder im Wesentlichen senkrecht zur Fahrzeuglängsachse verläuft. Die Bewegungsbahn kann also parallel zu einer gedachten Vertikalen oder aber schräg zu einer gedachten Horizontalen verlaufen. Dabei ist die Hebelmechanik vorzugsweise so ausgeführt, dass trotz des Versatzes des Aktuators gegenüber dem Eingelenkscharnier in Fahrzeuglängsrichtung die Fronthaube bei einer Verlagerung in Schutzposition praktisch keine Bewegungskomponente in x-Richtung, das heißt also in Richtung der Fahrzeuglängsachse, oder alternativ nur eine definierte, vorgebbare und vorzugsweise einstellbare kleine Bewegungskomponente in x-Richtung aufweist. Die Bewegung der Fronthaube relativ gegenüber dem Karosserierohbau ist daher durch die Wahl der Hebelverhältnisse, Anlenk- und Lagerpunkte der Hebelmechanik so einstellbar, dass eine Kollision der Fronthaube bei ihrem Anheben aus der Normal- in die Schutzposition mit dem Rohbau ausgeschlossen werden kann.Especially preferred is an embodiment the bonnet assembly, wherein the lever mechanism is formed is that the single joint hinge is displaceable along a movement path, in the vertical direction (z-direction), ie perpendicular or substantially perpendicular to the vehicle's longitudinal axis runs. The trajectory can therefore be parallel to an imaginary vertical or at an angle to an imaginary horizontal. Here is the lever mechanism preferably carried out so that in spite of the offset of the actuator relative to the single-pivot hinge in the vehicle longitudinal direction the bonnet at a shift in protective position practically no component of motion in the x-direction, this means So in the direction of the vehicle longitudinal axis, or alternatively only a defined, predetermined and preferably adjustable small Movement component in x-direction having. The movement of the front hood relative to the Bodyshell construction is therefore due to the choice of leverage, Anlenk- and bearing points of the lever mechanism so adjustable that a Collision of the front hood when lifting from the normal to the Protective position can be excluded with the shell.
Besonders bevorzugt wird ein Ausführungsbeispiel der Fronthaubenanordnung, die sich dadurch auszeichnet, dass die Hebelmechanik als modulare, vormontierbare Baueinheit ausgebildet ist, die in einem Vormontageschritt entweder an der Fronthaube oder am Karosserierohbau angebracht werden kann. Möglich ist auch, dass beispielsweise in der Rohbaumontage unter Verwendung der Hebelmechanik die Motorhaube montiert und justiert wird. In einem weiteren Schritt wird nach der Lackierung in der Montage der Aktuator eingesetzt und mit der Hebelmechanik verbunden. Dabei wird die Motorhaube nicht verstellt.Especially preferred is an embodiment the bonnet assembly, which is characterized in that the Lever mechanism designed as a modular, preassembled unit is in a pre-assembly step either on the front hood or can be attached to the body shell. It is also possible that, for example, in the bodyshell assembly using the lever mechanism the hood is mounted and adjusted. In a further step is after the paint used in the assembly of the actuator and with the Lever mechanism connected. The bonnet will not be adjusted.
Weitere vorteilhafte Ausführungsbeispiele der Fronthaubenanordnung ergeben sich aus Kombinationen der in den Unteransprüchen genannten Merkmale.Further advantageous embodiments of Bonnet arrangement result from combinations of the features mentioned in the subclaims.
