Abstract
Die Erfindung bezieht sich auf einen Hohlkörper als Verbundkörper, an den unterschiedliche Anforderungen, sowie an Innen- und Außen- Wandungen wie auch unterschiedlich an Außen- und Innen-Wandungen gestellt werden, wobei der Hohlkörper aus verschiedenen Werkstoffen zusammen umgeformt die unterschiedlichsten Querschnittsformen und Gestaltungen aufweisen kann.The invention relates to a hollow body as a composite body, to which different requirements are placed, as well as on inner and outer walls as well as different outer and inner walls, whereby the hollow body can have the most varied cross-sectional shapes and designs when formed from different materials.
Description
Die Erfindung betrifft einen mehrschichtigen Hohlkörper mit einer Außenschicht aus Metall nach dem Oberbegriff des Patentanspruches 1.The invention relates to a multilayer hollow body with an outer layer made of metal according to the preamble of patent claim 1.
Aus der DE-OS 32 21 333 ist ein als Wellschlauch ausgebildeter Hohlkörper dieser Art bekannt geworden, bei dem von einem mit Kunststoff verkleideten, zylindrischen Schlauch ausgegangen wird, die Wellung für beide Lagen gleichzeitig durchgeführt wird und dadurch weitere Verbindungsmaßnahmen zwischen Außen- und Innenschicht unnötig werden.From DE-OS 32 21 333, a hollow body of this type designed as a corrugated hose has become known, in which a cylindrical hose covered with plastic is used as the starting point, the corrugation is carried out for both layers simultaneously and thus further connection measures between the outer and inner layers are unnecessary.
Derartige Wellschläuche mögen zwar unterschiedlichen Anforderungen an Außen- und Innenwandung genügen, eignen sich aber nicht für die Übertragung von Kräften und sind daher als Konstruktionselement nicht geeignet.Such corrugated hoses may meet different requirements for the outer and inner walls, but they are not suitable for the transmission of forces and are therefore not suitable as a construction element.
Es ist daher Aufgabe der Erfindung, einen gattungsgemäßen mehrschichtigen Hohlkörper zu schaffen, der auch für die Übertragung und die Aufnahme von großen Kräften geeignet ist.It is therefore an object of the invention to create a generic multi-layer hollow body which is also suitable for the transmission and absorption of large forces.
Die Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.The object is achieved according to the invention by the features listed in the characterising part of patent claim 1.
Durch den Einsatz unterschiedlicher Werkstoffe für die Innenwandung und für die Außenwandung des Hohlkörpers kann dieser optimal an die unterschiedlichsten Anforderungen angepaßt werden, wobei eine nachträgliche feste Verbindung zwischen den Körperschichten durch Vernieten, Verschrauben, Verschweißen und andere Verbindungsarten erübrigt wird, da durch das gemeinsame Umformen ein fester Sitz gewährleistet ist. Es sind auch Hohlkörper mit sehr unterschiedlichen Querschnitten herstellbar.By using different materials for the inner and outer walls of the hollow body, it can be optimally adapted to a wide range of requirements, whereby a subsequent fixed connection between the body layers by riveting, screwing, welding and other types of connection is no longer necessary, since a tight fit is ensured by the joint forming. Hollow bodies with very different cross-sections can also be produced.
Ein weiterer großer Vorteil des erfindungsgemäßen Hohlkörpers besteht darin, daß beispielsweise Innen- oder Außen-Teile der Kombination, je nach dem, ob an die Innenoberfläche oder an die Außenoberfläche des Hohlkörpers besondere Anforderungen gestellt werden, mit relativ geringer Schichtdicke aus hochwertigem Material herstellbar sind, und entsprechend andere Schichten des Hohlkörpers aus preiswertem Material als Stützorgan mit größerer Schichtdicke herstellbar sind.Another great advantage of the hollow body according to the invention is that, for example, inner or outer parts of the combination, depending on whether special requirements are placed on the inner surface or on the outer surface of the hollow body, can be produced with a relatively small layer thickness from high-quality material, and correspondingly other layers of the hollow body can be produced from inexpensive material as a supporting element with a greater layer thickness.
Die Zwischenschicht des erfindungsgemäßen Hohlkörpers kann unterschiedlichste Vorteile bringen; beispielsweise kann sie einen Ausgleich zwischen innerem und äußerem Werkstoff gewährleisten, wenn diese bei Temperaturbelastung unterschiedliche Ausdehnungskoeffizienten aufweisen, oder aber auch als Wärmeisolierschicht zwischen Außen- und Innenschicht dienen.The intermediate layer of the hollow body according to the invention can bring a wide variety of advantages; for example, it can ensure a balance between the inner and outer material if they have different expansion coefficients under temperature stress, or it can also serve as a heat insulating layer between the outer and inner layer.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous further developments of the invention emerge from the subclaims.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. In der Zeichnung zeigtAn embodiment of the invention is explained in more detail below with reference to the drawing. The drawing shows
Fig. 1 einen Schnitt durch ein mehrschichtiges Kugelgehäuse, Fig. 1 a section through a multilayer ball housing,
Fig. 2 eine Seitenansicht nach der Fig. 1 und Fig. 2 is a side view according to Fig. 1 and
Fig. 3 einen Querschnitt nach dem Schnitt III- III der Fig. 2. Fig. 3 is a cross-section along section III-III of Fig. 2.
In den Fig. 1 bis 3 ist ein Kugelgehäuse dargestellt, mit einer Außenschicht 1, einer Innenschicht 2 und einer Zwischenschicht 3. Die drei Hohlkörperschichten 1 bis 3 sind gemeinsam zu einem Kugelgehäuse umgeformt. Figures 1 to 3 show a ball housing with an outer layer 1 , an inner layer 2 and an intermediate layer 3. The three hollow body layers 1 to 3 are formed together to form a ball housing.
