Abstract

In order to increase to a decisive extent the bending strength in the case of an elongate casting which is subjected to bending stress and consists of a metallic material, a sheet-metal rail which exhibits a hat profile is fixed in a frictionally locking and/or positively locking manner on the casting, transversely with respect to the directions of bending stress, such that the casting and the sheet-metal rail form a closed channel.

Description

Die Erfindung betrifft ein auf Biegung beanspruchtes, lang­ gestrecktes Gußteil aus einem metallischen Werkstoff.The invention relates to a long, claimed on bend stretched casting from a metallic material.

Um bei Gußteilen ein gleichmäßiges Gefüge zu erhalten, ist es notwendig, daß bestimmte Wandstärken nicht überschritten und Materialanhäufungen vermieden werden. Durch die Wahl eines geeigneten Gußwerkstoffes und Verrippung besonders belasteter Bereiche ist es möglich, das Gußteil hochbelast­ bar zu gestalten. Die zur Einhaltung der Festigkeitsan­ forderungen vielfach notwendige komplizierte Rippenform stellt einen wesentlichen Kostenfaktor dar und ist Ursache einer verhältnismäßig hohen Ausschußquote.In order to obtain a uniform structure in the case of castings it is necessary that certain wall thicknesses are not exceeded and material accumulations can be avoided. By choice a suitable casting material and ribbing in particular contaminated areas, it is possible to subject the casting to high loads to design bar. The compliance with the strength requirements often necessary complicated rib shape represents an essential cost factor and is the cause a relatively high reject rate.

Aufgabe der Erfindung ist, ein auf Biegung beanspruchtes, langgestrecktes Gußteil zu schaffen, das bei einfacher gießtechnisch leicht beherrschbarer Ausgestaltung mit ein­ fachen Maßnahmen zu einem hochfesten, insbesondere hohe Biegekräfte aufnehmenden Bauteil umgestaltet werden kann. The object of the invention is a elongate casting to create that at easier Casting easily controllable design with a fold measures to a high-strength, especially high Bending forces absorbing component can be redesigned.  

Diese Aufgabe wird bei einem Gußteil nach dem Oberbegriff des Patentanspruches 1 erfindungsgemäß durch dessen kenn­ zeichende Merkmale gelöst, wobei durch die Schaffung eines Kanales die Möglichkeit besteht, diesen z.B. als Kabelkanal oder Luftführungskanal einzusetzen.This task is for a casting according to the preamble of claim 1 according to the invention by its characteristics Characteristic features solved, by creating a Channel there is the possibility, e.g. as a cable duct or use an air duct.

Eine noch höhere Festigkeit der Blechschiene gegen Aus­ knicken wird erreicht, wenn diese mindestens eine in ihrer Längsrichtung verlaufende Sicke aufweist.An even higher strength of the sheet metal rail against Aus buckling is achieved when this has at least one in it Has longitudinal bead.

Bei einem bevorzugten Ausführungsbeispiel der Erfindung ist das Gußteil vorzugsweise im Bereich der Blechschienen­ befestigung mit einer quer zu den Biegebelastungsrichtungen sich erstreckenden Rippe versehen. Diese kann zur form­ schlüssigen Abstützung der Blechschiene herangezogen werden und gleicht die insbesondere durch Schraubstellen entstehen­ den Schwächungsstellen aus.In a preferred embodiment of the invention the casting is preferably in the area of the sheet metal rails fastening with a cross to the bending load directions extending rib provided. This can form conclusive support of the sheet metal rail can be used and resembles those created especially by screwing points the weak points.

Der Gegenstand der Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The subject matter of the invention is described below using a shown in the drawing embodiment closer explained.

Ein langgestreckter Endabschnitt 1 eines nicht näher dar­ gestellten Gußteiles 2, das durch Biegung entsprechend den durch einen Doppelpfeil kenntlich gemachten Biegebelastungs­ richtungen "A" und "B" beaufschlagt wird, ist quer zu diesen Belastungsrichtungen mit einer aufgesetzten, hutförmig profilierten Blechschiene 3 versehen, wobei durch eine Blechschienenbefestigung 4 mittels Schrauben 5 eine kraftschlüssige und durch eine in Erstreckungsrichtung der Blechschiene 3 verlaufende, vom Gußteil 2 nahe der oberen Blechschienenbefestigung 4 abragende Rippe 6 auch eine formschlüssige Verbindung geschaffen wird. Wie strich­ punktiert angedeutet, kann durch Herumführen des unteren Abschnittes der Blech­ schiene 3 um eine untere, abgesetzte Rippe 7 des Gußteiles 2 eine weitere formschlüssige Abstützung geschaffen werden. Als weitere versteifende Maßnahme ist die Blechschiene 3 mit einer in ihrer Längserstreckungsrichtung verlaufenden Sicke 8 versehen.An elongated end portion 1 of a casting 2 is not shown , which is acted upon by bending in accordance with the indicated by a double arrow bending directions "A" and "B" is transverse to these loading directions with an attached, hat-shaped profiled sheet metal rail 3 , wherein by means of a sheet metal rail fastening 4 by means of screws 5 a positive connection and also by a rib 6 extending from the casting 2 near the upper metal rail fastening 4 and extending in the direction of extension of the metal rail 3 , a positive connection is also created. As indicated by a dash-dotted line, another positive support can be created by moving the lower section of the sheet metal rail 3 around a lower, offset rib 7 of the cast part 2 . As a further stiffening measure, the sheet metal rail 3 is provided with a bead 8 running in its longitudinal direction.

Die aufgesetzte Blechschiene 3 bildet zusammen mit dem Gußteil 2 einen lediglich stirnseitig offenen Kanal 9, der gemäß dem dargestellten Ausführungsbeispiel einen Kabel­ strang 10 geschützt aufnimmt.The attached sheet metal rail 3 forms, together with the casting 2, a channel 9 which is only open at the end and which, according to the exemplary embodiment illustrated, receives a cable strand 10 in a protected manner.
