Description

Leichtmetall-Blechrad, insbesondere für Kraftfahrzeuge Die Erfindung betrifft ein Leichtmetall-Blechrad gemäß dem Oberbegriff des Patentanspruchs 1. Light metal sheet metal wheel, in particular for motor vehicles The invention relates to a light metal sheet metal wheel according to the preamble of claim 1.

Bei Verwendung von Lelchtmetallen, Insbesondere Aluminium und Aluminiumlegierungen, kann es bekanntlich nachteilig sein, die Einzelteile des Slechrads durch Schweißungen zu verbinden, wie dies bei Stahirädern üblich ist. Im Bereich der Schweißverbindungen ergeben sich nämlich nachteilige Beeinflussungen der Festigkeitseigenschaften, die durch zusätzliche Wärmebehandlungen rückgängig gemacht werden müssen. Daher ist aus der DE-OS 32 15 029, B6OB 3/02, bereits ein Aluminiumrad bekannt, das durch einen Formprozeß aus einer einzigen Aluminiumplatte einteilig hergestellt ist. Abgesehen davon, daß eine derartige Formgebung ein kompliziertes Werkzeug erfordert, ist es schwierig die erforderliche Festigkeit dieses Rades im Betrieb sicherzustellen. ähnliches gilt für das aus der DE-DS 28 24 972, B60B 3/02, bekannte Kraftfahrzeugrad, das aus zwei Teilen zusammengesetzt ist. Eines dieser Teile ist etwa topfförmig gestaltet und bildet die Radschüssel sowie den größten Teil der Feige, während das andere, etwa ringförmige abgesetzte Teil die Felge vervollständigt und mit dem erstgenannten Teil im Bereich des Felgenbetts formschlüssig, beispielsweise über ein Gewinde, verbunden ist.When using light metals, especially aluminum and aluminum alloys, it can be known to be disadvantageous to weld the individual parts of the slech wheel to connect, as is usual with steel wheels. In the area of welded connections that is, there are adverse effects on the strength properties that must be reversed by additional heat treatments. thats why from DE-OS 32 15 029, B6OB 3/02, an aluminum wheel is already known that by a molding process is made in one piece from a single aluminum plate. Apart from that of the fact that such a shaping requires a complicated tool, it is difficult to ensure the required strength of this wheel in operation. The same applies to the motor vehicle wheel known from DE-DS 28 24 972, B60B 3/02, which is composed of two parts. One of these parts is roughly pot-shaped designs and forms the wheel dish as well as most of the fig, while the other, approximately annular stepped part completes the rim and with the former Part in the area of the rim bed positively, for example via a thread, connected is.

Der Erfindung liegt mithin die Aufgabe zugrunde, ein Leichtmetall-Blechrad gemäß dem Oberbegriff des Patentanspruchs 1 zu schaffen, das ebenfalls Schweißverbindungen mit ihren Nachteilen vermeidet, aber mit relativ einfachen Ziehwerkzeugen hergestellt werden kann und eine hohe Festigkeit besitzt.The invention is therefore based on the object of a light metal sheet metal wheel to create according to the preamble of claim 1, which also welded connections avoids with its disadvantages, but manufactured with relatively simple drawing tools can be and has a high strength.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Patentanspruchs 1, vorteilhafte Ausbildungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the characterizing Features of claim 1, describe advantageous embodiments of the invention the subclaims.

Ein besonderer Vorteil der erfindungsgemäßen Konstruktion ist darin zu sehen, daß durch die Umbördelung der Felgenhörner zugleich zwei Teilaufgaben gelöst werden, indem durch die so geformten Felgenhörner einerseits formschlüssige Verbindungen zwischen der Felge und der Radschüssel hergestellt werden und andererseits durch diese Umbördelungen eine wesentliche Versteifung des Rads erzielt wird.A particular advantage of the construction according to the invention is therein to see that the flanging of the rim flanges also has two subtasks be solved by on the one hand form-fitting through the rim horns formed in this way Connections between the rim and the wheel disc are made and on the other hand through these flanges a substantial stiffening of the wheel is achieved.

Ein Ausführungsbeisplel der Erfindung wird im folgenden anhand der Zeichnung erläutert, deren Fig. 1 einen Axialschnitt und deren Fig. 2 die in Fig. 1 bei 1I angedeutete Ansicht wiedergeben.An exemplary embodiment of the invention is described below with reference to FIG Drawing explained, of which Fig. 1 is an axial section and Fig. 2 shows the in Fig. 1 reproduce the view indicated at 1I.

Die Hauptbestandteile des dargestellten Blechrads, dessen Radachse mit a bezeichnet ist, sind die Felge 1 mit dem Felgenbett 2 und die Radschüssel 3, die aus den beiden Formteilen 4 und 5 besteht. Die Felge 1 besteht beispielsweise aus einer Alumlnium-Magnesium-Legierung und kann in an sich bekannter Weise aus einem stranggepreßten Rohrabschnitt oder aus Band durch Roliverformung und Stumpf Schweißung hergestellt sein. Die beiden Blechformtelle 4 und 5, die die Radschüssel 3 bilden, können aus einer Aluminium-Magneslum-Mangantegierung bestehen. Alle Blechformtelle können eine Stärke von 3 bis 4 mm besitzen.The main components of the sheet metal wheel shown, its wheel axle is denoted by a, the rim 1 with the rim base 2 and the wheel disc 3, which consists of the two molded parts 4 and 5. The rim 1 consists for example made of an aluminum-magnesium alloy and can be made in a known manner an extruded pipe section or from tape by roll forming and stump Be welded. The two sheet metal moldings 4 and 5, which are the wheel disc 3 can be made of an aluminum-magneslum-manganese alloy. All sheet metal parts can have a thickness of 3 to 4 mm.

Betrachtet man zunächst die Formgebung der Felgenhörner 6 und 7, so sind diese in Richtung auf die Radachse a umgebördelt, so daß sie Aufnahmen für die ebenfalls gebördelten Ränder 8 und 9 der beiden die Radschüssel 3 bildenden Blechformteile 4 und 5 bilden. Im Bereich der Felgenhörner 6 und 7 finden sich demgemäß formschlüssige feste Verbindungen zwischen der Felge 1 einerseits und der Radschüssel 3 andererseits; irgendwelche Schweißverbindungen sind vermieden. Dle Umbördelungen im Bereich der Felgenhörner 6 und 7 erhöhen außerdem spürbar die Festigkeit des Blechrads.If one first considers the shape of the rim flanges 6 and 7, see above these are flanged in the direction of the wheel axle a so that they are shots for the likewise flanged edges 8 and 9 of the two forming the wheel disc 3 Form sheet metal parts 4 and 5. In the area of the rim horns 6 and 7 are accordingly found form-fitting solid connections between the rim 1 on the one hand and the wheel disc 3 on the other hand; any welded connections are avoided. The flanges in the area of the rim horns 6 and 7 also noticeably increase the strength of the Sheet metal wheel.

Betrachtet man nun die Formgebung der Blechformteile 4 und 5 im einzelnen, so verläuft das Blechformtell 4 im wesentlichen konzentrisch zum Felgenhorn 6, während das andere Blechtormtell 5, ausgehend von seinem achsnahen Bereich 1l, der auf dem achsnahen Bereich 10 des Blechtormteils 4 aufliegt, etwa konisch oder kegelförmig unter Abstützung des Felgenbetts 2 in Richtung auf das andere Felgenhorn 7 verläuft, wo sein Rand 9 formschlüssig festgelegt ist.If we now consider the shape of the sheet metal parts 4 and 5 in detail, so the sheet metal part 4 runs essentially concentrically to the rim flange 6, while the other sheet metal plate 5, starting from its near-axis area 1l, which is on the near the axis area 10 of the sheet metal part 4 rests, approximately conical or conical runs with the support of the rim bed 2 in the direction of the other rim flange 7, where its edge 9 is fixed in a form-fitting manner.

Das Blechformteil 4 ragt mit ausgedrückten, jeweils eine Offnung begrenzenden Bereichen 12 in Ausnehmungen 13 in dem anderen Blechtormtell 5 hinein, die zur Belüftung der Bremse dienen.The shaped sheet metal part 4 protrudes with expressed, each delimiting an opening Areas 12 in recesses 13 in the other sheet metal plate 5 into it, for ventilation serve the brake.

Im Nabenbereich 14 ist in der Abbiegung 15 des Biechformteils 5 die Verstärkungsschelbe 16 gehalten, die ebenfalls aus einem Leichtmetailwerkstoff, beispielsweise einer Aluminium-MagnesiumZegierung, bestehen kann.In the hub area 14 in the bend 15 of the bent part 5 is the Reinforcement disc 16 held, which is also made of a light metal material, for example an aluminum-magnesium alloy.

Alle drei Biechformteile sind mit üblichen, keine komplizierten Werkzeuge erfordernden Herstellungsschritten produzierbar, und auch die Festlegung der Ränder 8 und 9 der Blechformteile 4 und 5 in den Feigenhörnern 6 und 7 erfolgt durch übliche Rollprozesse.All three bent moldings come with standard, not complicated, tools required manufacturing steps, and also the definition of the edges 8 and 9 of the shaped sheet metal parts 4 and 5 in the fig horns 6 and 7 is made by usual Rolling processes.
