Abstract
Description
Die Erfindung bezieht sich auf eine Vorderachse für ein Kraftfahrzeug mit einer quer zum Fahrzeug angeordneten Blattfeder nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a front axle for a motor vehicle with a cross leaf spring arranged to the vehicle according to the preamble of patent claim 1.
Aus der US 3,181,641 ist eine quer angeordnete Blattfeder für ein Kraftfahrzeug als Radführungselement bekannt. Die Blattfeder ist rechteckförmig ausgebildet und zu beiden Seiten einer Längsmittelachse des Fahrzeugs in einem Halteelement elastisch und schwenkbar gelagert, wobei das Halteelement mit einem Längsträger verbunden ist. Die freien Enden der Blattfeder sind mit einem Schwenklager verbunden. Zur Radführung ist desweiteren ein Radführungslenker vorgesehen, der ebenfalls mit dem Schwenklager verbunden ist.From US 3,181,641 a transverse leaf spring for a motor vehicle is known as Wheel guide element known. The leaf spring is rectangular and closed elastic on both sides of a longitudinal central axis of the vehicle in a holding element and pivotally mounted, the holding element being connected to a side member is. The free ends of the leaf spring are connected to a swivel bearing. For Wheel guidance is also provided a wheel control arm, which also with the Swivel bearing is connected.
Aufgabe der Erfindung ist es, eine verbesserte Vorderachse mit einer quer angeordneten Blattfeder für eine Vorderachse eines Kraftfahrzeuges zu schaffen, die als Radführungsglied ausgebildet ist.The object of the invention is to provide an improved front axle with a cross arranged leaf spring for a front axle of a motor vehicle to create the is designed as a wheel guide member.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the features of claim 1. The dependent claims contain further advantageous features.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß mit der Blattfeder aufgrund der Ausbildung mit zwei Armen im Bereich einer Lagerung an einem aufbauseitig befestigbaren Querträger eine definierte Längssteifigkeit erzielt wird. Diese Längssteifigkeit ist insbesondere vorteilig bei auf das Rad einwirkenden Bremskräften, damit eine optimale Radführung gewährleistet ist.The main advantages achieved with the invention are that with the Leaf spring due to the training with two arms in the area of a bearing a cross member that can be attached to the body achieves a defined longitudinal rigidity becomes. This longitudinal stiffness is particularly advantageous when acting on the wheel Braking forces to ensure optimal wheel guidance.
Die Arme der Blattfeder bilden zwischen sich einen Freiraum, so daß die Stützbasis den Gegebenheiten des Fahrzeugs anpaßbar ist. Die gesamte Breitendimensionierung der Arme entspricht etwa der Breite des freien Endes der Blattfeder. The arms of the leaf spring form a space between them, so that the support base is adaptable to the conditions of the vehicle. The entire width dimensioning the arm corresponds approximately to the width of the free end of the leaf spring.
Die Verbindung der Blattfeder mit dem Querträger erfolgt in einfacher Weise unter Zwischenschaltung von einem elastischen Lager, das eine Distanzbuchse umfaßt. Hierdurch wird eine gewisse Längselastizität erzielt, damit Rollgeräusche vermieden werden können.The connection of the leaf spring to the cross member is carried out in a simple manner Interposition of an elastic bearing that includes a spacer. This achieves a certain longitudinal elasticity so that rolling noises are avoided can be.
Die freien Enden der Blattfeder sind jeweils mit einem Schwenklager verbunden, wobei diese Verbindung über eine Halteplatte oder dergleichen erfolgen kann.The free ends of the leaf spring are each connected to a pivot bearing, wherein this connection can be made via a holding plate or the like.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is in following described in more detail.

Fig. 1 eine Draufsicht auf eine Blattfeder mit verbundenem Querträger und Fig. 1 is a plan view of a leaf spring with a connected cross member and
Fig. 2 einen Schnitt durch eine Lagerung der Blattfeder nach der Linie II-II der Fig. 1. Fig. 2 shows a section through a support of the leaf spring according to the line II-II in FIG. 1.
In Fig. 1 ist eine quer im Fahrzeug angeordnete Blattfeder 1 mit einem Querträger 2 gezeigt, wobei die Blattfeder 1 zu beiden Seiten einer Fahrzeugmittellängsachse L im Querträger 2 in Halterungen 3 abgestützt gelagert ist.In Fig. 1, a transverse leaf spring in the vehicle 1 is shown with a cross member 2, wherein the leaf spring is rotatably supported on both sides of a vehicle 1 central longitudinal axis L in the cross member 2 in holders 3.
Die Blattfeder 1 weist im Bereich der Halterungen 3 jeweils zwei Arme 4, 5 auf, die einteilig mit der Blattfeder ausgebildet sind. Diese Arme 4, 5 bilden in Fahrzeuglängsrichtung - in der Breite gesehen - eine Basis B zur Längskraftabstützung.The leaf spring 1 has in the area of the brackets 3 two arms 4 , 5 , which are formed in one piece with the leaf spring. These arms 4 , 5 form a base B for longitudinal force support in the vehicle longitudinal direction, as seen in width.
Zwischen den beiden Armen 4, 5 ist ein Freiraum 6 vorgesehen, der sich bis zum Mittelteil 7 und bis in das freie Ende des Blattfederstranges 8 erstrecken kann. Die beiden Arme 4, 5 weisen jeweils eine Breite b auf, die insgesamt etwa der Gesamtbreite C der Blattfeder 7 am freien Ende entspricht. A free space 6 is provided between the two arms 4 , 5 and can extend as far as the middle part 7 and into the free end of the leaf spring strand 8 . The two arms 4 , 5 each have a width b, which overall corresponds approximately to the total width C of the leaf spring 7 at the free end.
In Fig. 2 ist der Einbauzustand der Blattfeder 1 näher dargestellt. Über Schrauben 9 ist die Blattfeder 1 samt Querträger 2 am Fahrzeugaufbau 10 gehalten. Zur elastischen Lagerung der Blattfeder 1 am Fahrzeugaufbau 10 bzw. am Querträger 2 dient ein elastisches Lager 11, bestehend aus einer Distanzbuchse 12 und einem umgebenden elastischen Element 13. Dieses nimmt zwischen sich die Blattfeder 1 bzw. die Arme 4, 5 auf, die ebenfalls über das elastische Element 13 beabstandet zum Querträger 2 gehalten werden. Die Schrauben 9 befestigen eine quer durchgehende Halteplatte 3, eine Schelle oder dergleichen, welche die Blattfeder 1 am Querträger 2 hält.The installation state of the leaf spring 1 is shown in more detail in FIG. 2. The leaf spring 1 together with the cross member 2 is held on the vehicle body 10 by means of screws 9 . An elastic bearing 11 , consisting of a spacer bush 12 and a surrounding elastic element 13, serves for the elastic mounting of the leaf spring 1 on the vehicle body 10 or on the cross member 2 . This receives between them the leaf spring 1 or the arms 4 , 5 , which are also held at a distance from the cross member 2 by the elastic element 13 . The screws 9 fasten a transversely continuous holding plate 3 , a clamp or the like, which holds the leaf spring 1 on the cross member 2 .
