Abstract
Description
Die Erfindung betrifft ein Achssystem für ein Fahrzeug nach dem Oberbegriff des Anspruchs 1.The The invention relates to an axle system for a vehicle according to the preamble of claim 1.
Von Zulieferfirmen werden Achssysteme oft in modulartiger Bauweise, bestehend aus einem meist rechteckförmigen, rahmenartigen Achsträger und einem Lenkgetriebe mit Spurstangen, Radlenkhebeln und mit an dem Achsträger gelenkig angeordneten Querlenkern, sowie Feder- Dämpfereinheiten angeliefert. Dies ist bei Vorderachssystemen und Hinterachssystemen der Fall. Kräfte, die im Betrieb des Fahrzeugs aus dem Lenkgetriebe, den Querlenkern und auch von einem etwaigen Antrieb von gelenkten Rädern aus einem Differential an dem Achsträger stammen, werden von dem Achsträger aufgenommen, der aus Stahl mit entsprechendem Gewicht gebildet ist.From Subcontractors often use axle systems in modular design, consisting of a usually rectangular, frame-like axle and a steering gear with tie rods, wheel steering levers and with the axle articulated wishbones, as well as spring damper units delivered. This is with front axle systems and rear axle systems the case. forces in the operation of the vehicle from the steering gear, the wishbones and also from any drive from steered wheels a differential on the axle carrier come from the axle carrier received, which is made of steel with appropriate weight.

Der Erfindung liegt die Aufgabe zugrunde, ein Achssystem für ein Fahrzeug zu schaffen, das gewichtsoptimiert ist und einen exakten Betrieb des Fahrzeugs ermöglicht.Of the Invention is based on the object, an axle system for a vehicle to create, which is weight-optimized and accurate operation of the vehicle allows.
Die Aufgabe wird mit einem Achssystem mit den Merkmalen des Anspruchs 1 gelöst.The Task is with an axis system with the features of the claim 1 solved.
Dadurch dass der Achsträger mit dem Lenkgetriebegehäuse so fest verbunden ist, dass der Achsträger und das Lenkgetriebegehäuse gemeinsam eine Struktur bilden, die in der Lage ist, alle auf sie geleiteten Kräfte und inneren Kräfte aufzunehmen, wobei das Lenkgetriebegehäuse so konstruiert ist, dass unzulässige Verformungen der Lenkung sicher vermieden sind, ist ein Achssystem geschaffen, das durch die strukturelle Einheit von Achsträger und Lenkgetriebegehäuse in der Lage ist, hohe Widerstandsmomente gegen Biegung und Torsion darzustellen, wodurch ein geringeres Gewicht des gesamten Achssystems ermöglicht ist. Die Einheit aus Achsträger und Lenkgetriebegehäuse ist dauertest ausgelegt.Thereby that the axle carrier with the steering gear housing is firmly connected so that the axle and the steering gear housing together form a structure that is able to handle all the forces and forces directed at it internal forces The steering gear housing is constructed so that inadmissible deformations the steering are safely avoided, an axle system is created, this is due to the structural unit of axle carrier and steering gear housing in the Able to represent high resistance moments against bending and torsion, whereby a lower weight of the entire axle system is possible. The unit of axle carrier and steering gear housing is designed to last.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred versions emerge from the dependent claims.
In einem besonders bevorzugten Ausführungsbeispiel bildet der Achsträger zusammen mit dem Lenkgetriebegehäuse einen geschlossenen Rahmen, wobei der Achsträger lösbar mit dem Lenkgetriebegehäuse verbunden sein kann. Das Lenkgetriebegehäuse ist so aufgebaut, dass es in Lage ist, bis zu etwa 50% der auf den Achsträger geleiteten Kräfte aufzunehmen. Bevorzugt ist der Achsträger aus einem Leichtmetall-Werkstoff, wie Magnesium oder aus einem Nichteisenmetall-Werkstoff, also beispielsweise auch aus faseverstärktem Kunststoff, wie beispielsweise aus KFK (Kohlefaserkunststoff) gebildet.In a particularly preferred embodiment forms the axle carrier together with the steering box a closed frame, wherein the axle carrier releasably connected to the steering gear housing can be. The steering gear housing is designed so that it is capable of up to about 50% of the axle guided forces take. The axle carrier is preferably made of a light metal material, such as magnesium or a non-ferrous metal material, so for example also made of fiber reinforced Plastic, such as made of KFK (carbon fiber plastic).
Die gesamte strukturelle Einheit aus Achsträger und Lenkgetriebegehäuse hat dennoch zumindest etwa die gleiche Steifigkeit und Festigkeit wie ein Achsträger aus einem Eisenmetall-Werkstoff insbesondere aus Stahl. An dem Lenkgetriebegehäuse sind vorzugsweise einstückig mit diesem gebildete Flansche angebracht, die vorzugsweise radial oder tangential von dem Lenkgetriebegehäuse abragen. Die Flansche dienen zur lösbaren oder zur steifen, stoffschlüssigen Verbindung (Knoten) des Lenkgetriebegehäuses mit dem Achsträger.The entire structural unit of axle carrier and steering gear housing has nevertheless at least about the same rigidity and strength as an axle carrier made of a ferrous metal material, in particular of steel. On the steering gear housing are preferably in one piece mounted with this formed flanges, preferably radially or tangentially protrude from the steering gear housing. The flanges serve for releasable or to the stiff, cohesive Connection (knot) of the steering gear housing to the axle carrier.
Die Flansche haben bevorzugt eine Dreiecksform als Grundriss, mit radial von dem Lenkgetriebegehäuse beabstandeter Spitze. Die Flansche können verrippt sein. Vorzugsweise sind die Flansche und die Rippen einstückig mit dem Lenkgetriebegehäuse gebildet.The flanges preferably have a triangular shape as a plan, with radially from the steering gear housing spaced tip. The flanges can be ribbed. Preferably, the flanges and the ribs are formed integrally with the steering gear housing.
Die Flansche weisen Montagebohrungen auf, um die Auflageflächen für den Achsträger angeordnet sind und an die die Rippen geführt sind. Die Flansche sind bevorzugt etwa in einer Ebene angeordnet und paarweise mit axialem Abstand zu beiden Längsseiten des Lenkgetriebegehäuses abragend. Zur Versteifung des Lenkgetriebegehäuses weist dieses eine Längsverrippung auf. Es ist vorzugsweise parallel zu einem Querträger des Achsträgers ausgerichtet und in einer besonders bevorzugten Ausführungsform des Achssystems zwischen zwei Querträgern des Achsträgers, parallel zu den Querträgern angeordnet. Somit werden bei dieser Ausführungsform zwei geschlossene Rahmen von dem Achsträger und dem Lenkgetriebegehäuse gebildet. Das Lenkgetriebegehäuse ist insbesondere mit vorgespannten Schraubverbindungen mit dem Achsträger verbunden, wobei selbstverständlich die Auflageflächen von Achsträger und Flansche des Lenkgetriebegehäuses an den Montagebohrungen der Flansche so dimensioniert sind, dass die Flächenpressung durch beispielsweise Durchsteckschrauben größer ist als die übertragenen Kräfte.The Flanges have mounting holes around the bearing surfaces are arranged for the axle and led to the ribs are. The flanges are preferably arranged approximately in one plane and projecting in pairs with axial distance to both longitudinal sides of the steering gear housing. For stiffening the steering gear housing, this has a longitudinal ribbing on. It is preferably parallel to a cross member of the axle carrier aligned and in a particularly preferred embodiment of the axle system between two cross beams of the axle beam, parallel to the crossbeams arranged. Thus, in this embodiment, two are closed Frame of the axle carrier and the steering gear housing educated. The steering gear housing is in particular connected to the axle carrier with prestressed screw connections, of course the bearing surfaces from axle carrier and flanges of the steering gear housing at the mounting holes of the flanges are dimensioned so that the surface pressure through, for example, through-bolts is greater than the transmitted Forces.
Es kann zweckmäßig sein, das Lenkgetriebegehäuse an einem oder mehreren Längsträgern oder Querträgern des Achsträgers festzulegen, wodurch sich die Steifigkeit der Struktur erhöhen lässt.It may be appropriate the steering gear housing on one or more longitudinal members or cross members of the axle carrier which increases the rigidity of the structure.
Das erfindungsgemäße Achssystem eignet sich zur Anwendung in Personen- oder Nutzkraftwagen mit Hilfskraft- oder Fremdkraftlenkung und gelenkter Vorder- und/oder Hinterachse.The Axis system according to the invention is suitable for use in passenger or commercial vehicles with auxiliary power or external power steering and steered front and / or rear axle.
