Abstract
Description
Die Verbindung zwischen einem Fahrzeugrad und der Fahrzeugachse wird von der Radaufhängung mit einer angestellten Radlagereinheit hergestellt, wobei ein Rad gewöhnlich über eine Radnabe und einem Wälzlager auf einem am Radträger angeordneten Achszapfen montiert ist. Der Achszapfen selbst und dessen Anbindung an den Radträger sind den über das Rad eingeleiteten zum Teil extremen Belastungen im Fahrbertrieb unmittelbar ausgesetzt und müssen deshalb zuverlässig ausgelegt und mit einer besonders hohen Qualität gefertigt werden. Gleichzeitig verfangt die gegenwärtige Entwicklung in der Automobilindustrie, dass bei gleichzeitig steigenden Fahrkomfort das Fahrzeuggewicht nicht übermäßi stark ansteigt, was zum Beispiel durch den zunehmenden Austausch von konventionellen Stahl- oder Gußwerkstoffen durch Leichtmetallwerkstoffe realisiert werden kann. Von dieser Entwicklung sind im zunehmenden Maße auch Fahrwerkkomponenten, insbesondere auch Radträger, betroffen.The connection between a vehicle wheel and the vehicle axle is engaged by the wheel suspension with a Manufactured wheel bearing unit, wherein a wheel usually has a wheel hub and a roller bearing on one on the wheel carrier arranged journal is mounted. The journal itself and its connection to the wheel carrier are the over the wheel initiated partly extreme loads in the driving operation immediately exposed and must therefore reliable designed and manufactured with a particularly high quality. simultaneously catches the current one Development in the automotive industry that while increasing Driving comfort the vehicle weight does not increase excessively, which leads to Example through the increasing exchange of conventional steel or cast materials can be realized by light metal materials. Of this Development are increasingly also chassis components, especially wheel carriers, affected.
Die Achszapfen für eine Radträgereinheit werden üblicherweise aus Stahl, beispielsweise mit der Werkstoffbezeichnung Cf 53, durch Warmformen (Gesenkschmieden) über mehrere Umformstufen gefertigt und spanend nachbearbeitet.The axle journals for a wheel carrier unit are usually made of steel, for example with the material designation Cf 53 Hot forming (drop forging) over several forming stages manufactured and machined.
Ein bekannter Radträger wird zunächst separat vom Achszapfen mittels eines Schwerkraft- oder Niederdruck-Gießverfahrens hergestellt, wobei es gießtechnisch günstig ist, den zur Anordnung des Achszapfens vorgesehenen Bereich des Radträgers bei diesen Verfahren für das Anschnitt- oder Speisersystem zu benutzen und das schmelzflüssige Material über die am Radträger zentral ausgebildete Radnabe einzugießen. Auf diese Weise kann aufgrund der hohen thermischen Symmetrie eine relativ gleichmäßige gerichtete Erstarrung des Gußwerkstoffes von den Außenbereichen nach innen zur Radnabe ohne die Bildung von Lunkern oder sonstigen die Qualität des Radträgers negativ beeinflussenden Strukturdefekten erfolgen.A well-known wheel carrier will first separately from the journal using a gravity or low pressure casting process manufactured, it being cast Cheap is the area provided for the arrangement of the journal Wheel carrier at this procedure for to use the gate or feed system and the molten material over the on the wheel carrier Pour in centrally trained wheel hub. In this way, due to the high thermal symmetry a relatively uniform directional solidification of the cast material from the outside areas inwards to the wheel hub without the formation of cavities or other the quality of the wheel carrier negative structural defects.
Zur Verbindung eines Achszapfens mit einem Radträger sind verschiedene Methoden bekannt, beispielsweise das Aufschrauben oder das Einpressen. Dazu muß an geschmiedeten Achszapfen neben der Aufnahmefläche für das Radlager insbesondere die zur Verbindung mit dem Radträger vorgesehene Fläche sehr genau bearbeitet werden, um beispielsweise mit der am Radträger ebenfalls sehr sorgfältig herzustellenden Zentralbohrung eine Presspassung eingehen zu können. Das Verschrauben des Achszapfens mit oder dessen Einpressen in den Radträger stellen insgesamt zusätzliche kosten- und arbeitsintensive Arbeitsgänge dar.For connecting an axle pin with a wheel carrier Various methods are known, for example screwing on or pressing in. To do this forged axle pins in addition to the receiving surface for the wheel bearing in particular the one intended for connection to the wheel carrier area can be processed very precisely, for example with the one on the wheel carrier careful to be able to make a press fit. The Place the axle journal with or press it into the wheel carrier total additional costly and labor-intensive operations.
Desweiteren ist mit der
Die
Aufgabe der Erfindung ist es, eine Radträgereinheit darzustellen, die kostengünstiger gefertigt werden kann.The object of the invention is a wheel carrier to represent the more cost-effective can be manufactured.
Die Erfindung löst die Aufgabe mit einer Radträgereinheit mit den Merkmalen des Anspruchs 1 und mit einer weiteren Radträgereinheit mit den Merkmalen des Anspruchs 2.The invention solves the problem with a wheel carrier unit with the features of claim 1 and with a further wheel carrier unit with the features of claim 2.
Dadurch, dass gemäß Anspruch 1 die Radträgereinheit als Verbundgußteil ausgebildet ist, wobei der Radträger als Gußteil aus einem ersten Werkstoff ausgeführt und der Achszapfen aus einem zweiten Werkstoff vorgefertigt ist und zumindest teilweise von dem Gußteil umgossen ist, kann im Vergleich zu einer aus zwei Teilen montierten Radträgereinheit eine Nachbearbeitung der gegenseitigen Anlageflächen und der Montagevorgang selbst entfallen. Somit können bei der Fertigung einer Radträgereinheit erhebliche Zeit- und Kosteneinsparungen erzielt werden. Bei der Ausführung des Radträgers aus einer Aluminium- und/oder Magnesiumlegierung wird zudem ein äußerst niedriges Gewicht bei einer sehr hohen Festigkeit erreicht.Characterized in that the wheel carrier unit according to claim 1 as a composite casting is formed, the wheel carrier as a casting made of a first material and the axle journal is prefabricated from a second material and at least partially by the casting is overmolded, compared to one made of two parts Wheel carrier unit one Post-processing of the mutual contact surfaces and the assembly process themselves eliminated. So you can considerable in the manufacture of a wheel carrier unit Time and cost savings can be achieved. When executing the wheel carrier an aluminum and / or magnesium alloy also becomes an extremely low one Weight reached with a very high strength.
Bei leichten Fahrzeugen, beispielsweise Elektrofahrzeugen oder generell Kleinwagen oder bei Fahrzeugen mit sechs und mehr Rädern kann infolge einer reduzierten Achsbelastung die Radträgereinheit gemäß Anspruch 2 als Gußteil ausgebildet werden, wobei der Achszapfen als integraler Bestandteil des Radträgers ausgeführt ist. Eine solche Ausführung ist insbesondere bei der Auswahl einer hochfesten Leichtmetalllegierung, insbesonder einer Aluminium- und/oder Magnesiumlegierung vorteilhaft.In light vehicles, for example electric vehicles or generally small cars or vehicles with six and more wheels can the wheel carrier unit due to a reduced axle load according to claim 2 as a casting be formed, with the journal as an integral part of the wheel carrier accomplished is. Such an execution is particularly important when choosing a high-strength light metal alloy, an aluminum and / or magnesium alloy is particularly advantageous.
Weitere vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.Further advantageous developments and embodiments of the invention are described in the subclaims.
Im Folgenden wird die Erfindung anhand eines Ausführungsbeispiels beispielhaft erläutert. Die einzige Figur stellt eine Perspektivdarstellung einer Radträgereinheit mit einem von einem Radträger umgossenen Achszapfen dar.The invention is described below of an embodiment exemplified. The single figure represents a perspective view of a wheel carrier unit with one of a wheel carrier cast axle journals.
Die Figur zeigt einen bekannten,
aus einem Stahlwerkstoff, beispielsweise mit der Bezeichnung 38MnSiVSMoCr,
mittels Warmumformen gefertigten zylindrisch, mehrfach gestuften

Zur Herstellung einer Radträgereinheit
Der Anguss erfolgt beim Gießen von einem der Radnabe entfernten Bereich. Vorzugsweise wird die Poral-Druckgußtechnologie eingesetzt, da diese ein turbulenzfreies Füllen der Druckgußform ermöglicht und somit porenarme Gußteile liefert.The sprue takes place when casting an area away from the wheel hub. Poral die casting technology is preferred used because this enables a turbulence-free filling of the die and thus low-pore castings supplies.
