Description
Die Erfindung betrifft ein Scharnier für eine Fronthaube eines Kraftfahrzeugs gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a hinge for a front hood of a motor vehicle according to the preamble of claim 1.
Aus dem Serienfahrzeugbau ist es bekannt, sogenannte aktive Scharniere für eine Fronthaube eines Kraftfahrzeugs vorzusehen, die einerseits zum Öffnen der Fronthaube für den Servicefall ausgelegt sind und andererseits eine Anstellung der Fronthaube im Falle eines Fußgängeranpralls ermöglichen. Hierfür sind für verschiedene Scharniertypen ganz unterschiedliche Konstruktionen entwickelt worden.From series vehicle construction it is known to provide so-called active hinges for a front hood of a motor vehicle, which on the one hand are designed to open the front hood for servicing and on the other hand enable the front hood to be adjusted in the event of a pedestrian impact. For this purpose, very different designs have been developed for different hinge types.
So ist beispielsweise für ein sogenanntes Viergelenkscharnier in der
Es ist Aufgabe der Erfindung ein Scharnier derart weiterzuentwickeln, dass unter Beibehaltung der Funktionalität der Herstellungsaufwand reduziert wird.It is the object of the invention to further develop a hinge in such a way that the manufacturing effort is reduced while maintaining the functionality.
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.The object is achieved according to the invention with the features of claim 1.
Vorteilhafte Ausgestaltungen ergeben sich aus den Merkmalen der nachgeordneten Ansprüche.Advantageous refinements result from the features of the subordinate claims.
Der Kern der Erfindung liegt darin, dass der im Stand der Technik notwendige Bolzen eingespart wird und stattdessen durch Schließelemente ersetzt wird, die vorzugsweise angeformt sind. Dass hat den Vorteil, dass Montageaufwand reduziert werden kann. Da Haubenteil und Koppelteil als Blechteile ausgebildet sind, können die Schließelemente lediglich durch Stanzen und Biegen hergestellt werden. Erfindungsgemäß umfasst das Scharnier ein haubenseitig befestigtes Scharnieroberteil und ein karosserieseitig befestigtes Scharnierunterteil, wobei das Scharnieroberteil und das Scharnierunterteil gelenkig miteinander verbunden sind. Das Scharnieroberteil setzt sich aus einem Haubenteil zur Festlegung an der Fronthaube und einem Koppelteil zur gelenkigen Verbindung mit dem Scharnierunterteil zusammen. Im normalen Betriebszustand des Kraftfahrzeugs, also zum Beispiel bei der Fahrt, im Stillstand und auch bei Öffnen und Schließen der Fronthaube zu Servicezwecken ist das Haubenteil gegenüber dem Koppelteil über ein Verriegelungselement verriegelt. Das Verriegelungselement steht dabei mit seiner Haltefläche mit einer korrespondierenden Fläche eines Schließelements in Eingriff. Im Falle eines Fußgängeraufpralls wird das Verriegelungselement vorzugsweise über einen Aktuator entriegelt, d.h. die beiden genannten Flächen sind dann nicht mehr im Eingriff miteinander. Gleichzeitig ist im Unterschied zum Stand der Technik wirkt eine Sperrfläche am Koppelteil mit einer korrespondierenden Fläche an einem zweiten Schließelement zusammen. Durch die räumliche Trennung von Haltefläche und Sperrfläche können beide in einfacher Weise am Haubenteil bzw. am Koppelteil angeformt sein.The essence of the invention lies in the fact that the bolt required in the prior art is saved and instead is replaced by closing elements, which are preferably integrally molded. This has the advantage that assembly work can be reduced. Since the hood part and the coupling part are designed as sheet metal parts, the closing elements can only be produced by punching and bending. According to the invention, the hinge comprises an upper hinge part fastened on the hood side and a lower hinge part fastened on the body side, the upper hinge part and the lower hinge part being connected to one another in an articulated manner. The upper part of the hinge is made up of a cover part for fixing to the front cover and a coupling part for the articulated connection with the lower part of the hinge. In the normal operating state of the motor vehicle, for example when driving, at a standstill and also when opening and closing the front hood for service purposes, the hood part is locked with respect to the coupling part via a locking element. The locking element is in engagement with its holding surface with a corresponding surface of a closing element. In the event of a pedestrian impact, the locking element is preferably unlocked via an actuator, i.e. the two surfaces mentioned are then no longer in engagement with one another. At the same time, in contrast to the prior art, a blocking surface on the coupling part interacts with a corresponding surface on a second closing element. Due to the spatial separation of the holding surface and the blocking surface, both can be molded onto the hood part or the coupling part in a simple manner.
Für die Ausbildung eines Viergelenkscharniers kann die gelenkige Verbindung zwischen dem Scharnierunterteil und dem Scharnieroberteil durch einen vorderen Lenker und einen hinteren Lenker gebildet sein, wobei die beiden Lenker jeweils mit einem Ende am Koppelteil angelenkt sind.For the formation of a four-bar hinge, the articulated connection between the lower hinge part and the upper hinge part can be formed by a front link and a rear link, with one end of the two links being hinged to the coupling part.
Für eine vereinfachte Herstellung kann das erste Schließelement durch Ausstanzen eines Segments im Haubenteil gebildet sein. Die zur Haltefläche korrespondierenden Fläche kann dann durch Umbiegen eines Flansches hergestellt werden, der einen Randbereich des Segments bildet.For a simplified production, the first closing element can be formed by punching out a segment in the hood part. The surface corresponding to the holding surface can then be produced by bending over a flange which forms an edge region of the segment.
In ähnlicher Weise kann das zweite Schließelement durch Ausstanzen eines Ausschnitts im Haubenteil gebildet sein. Anschließend wird die zur Sperrfläche korrespondierende Fläche des Schließelements durch Umbiegen eines Flansches gebildet.In a similar way, the second closing element can be formed by punching out a cutout in the hood part. The surface of the closing element that corresponds to the blocking surface is then formed by bending over a flange.
Für den Spielausgleich kann ein Puffer zwischen der Sperrfläche des Koppelteils und der korrespondierenden Fläche des Schließelements angeordnet sein. Dieser Puffer kann wahlweise an der Sperrfläche oder an der korrespondierenden Fläche befestigt sein.To compensate for play, a buffer can be arranged between the blocking surface of the coupling part and the corresponding surface of the closing element. This buffer can optionally be attached to the blocking area or to the corresponding area.
Vorzugsweise kann die Sperrfläche durch Umbiegen eines Abschnitts des Koppelteils gebildet werden.The blocking surface can preferably be formed by bending over a section of the coupling part.
