Abstract
Vorrichtung zum Befestigen eines Abgaskrümmers am Motorblock eines Verbrennungsmotors aufweisend a) ein erstes Halterteil (10) mit zwei ersten Befestigungsöffnungen (11) für eine Schraubbefestigung am Motorblock sowie zwei Befestigungsöffnungen (12) für eine Schraubbefestigung eines zweiten Halterteils (20) und b) ein zweites winkelförmiges Halterteil (20) mit einem dem ersten Halterteil (10) zugewandten Winkelschenkel (21) mit zweiten Befestigungsöffnungen (22) und einem zweiten Winkelschenkel (23) mit dritten Befestigungsöffnungen (24), wobei die beiden Winkelschenkel (21, 23) winklig zueinander angeordnet sind dadurch gekennzeichnet, dass c) der dem ersten Halterteil (10) zugewandte Winkelschenkel (21) die zwei zweiten Befestigungsöffnungen (22) aufweist und d) das dem Winkelschenkel (21) gegenüberliegende freie Ende des zweiten Winkelschenkels (23) gabelförmig ausgebildet zwei nebeneinender angeordnete Schenkel mit jeweils einer der dritten Befestigungsöffnung (24) aufweist und e) die Befestigungsöffnungen (11, 22, 24) als Langlöcher ausgebildet sind und die Längsachsen von wenigstens zwei der Befestigungsöffnungen (22, 24) im zweiten winkelförmigen Halterteil (20) senkrecht zueinander orientiert sind.A device for fastening an exhaust manifold on the engine block of an internal combustion engine comprising a) a first holder part (10) with two first attachment openings (11) for a screw fastening to the engine block and two mounting holes (12) for a screw fastening a second holder part (20) and b) a second angular holder part (20) with an angle leg (21) facing the first holder part (10) with second attachment openings (22) and a second angle leg (23) with third attachment openings (24), wherein the two angle legs (21, 23) are arranged at an angle to one another are characterized in that c) of the first holder part (10) facing the angle leg (21) has the two second mounting holes (22) and d) the angle leg (21) opposite the free end of the second angle leg (23) fork-shaped two nebeneinender arranged Up each leg with one of the third mounting hole (24) e) and e) the attachment openings (11, 22, 24) are formed as oblong holes and the longitudinal axes of at least two of the attachment openings (22, 24) in the second angle-shaped holder part (20) are oriented perpendicular to one another.
Description
Die Erfindung betrifft Vorrichtungen zum Befestigen eines Abgaskrümmers am Motorblock eines Verbrennungsmotors gemäß dem Oberbegriff des Anspruchs 1.The invention relates to devices for fastening an exhaust manifold on the engine block of an internal combustion engine according to the preamble of claim 1.
Bei der Befestigung eines Abgaskrümmers am Motorblock stellt man fest, dass erhebliche Bauteil- und Maßtoleranzen auftreten. Da während der Bandmontage eine individuelle Auswahl nicht möglich ist, werden die Bauteile je nach der Toleranzlage mit Zug- oder Druckspannung montiert. Dies erschwert nicht nur die Montage sondern reduziert auch die Dauerhaltbarkeit. Das ist unbefriedigend.When mounting an exhaust manifold on the engine block, it is noted that significant component and dimensional tolerances occur. Since an individual selection is not possible during tape assembly, the components are mounted with tensile or compressive stress, depending on the tolerance position. This not only complicates the assembly but also reduces the durability. That is unsatisfactory.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Befestigungsvorrichtung der eingangs genannten Art anzugeben, die eine Montage ohne schädliche Spannungen erlaubt.The present invention has for its object to provide a fastening device of the type mentioned above, which allows mounting without harmful voltages.
Diese Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des Anspruchs 1.This object is achieved by a device having the features of claim 1.
Die erfindungsgemäße Haltevorrichtung zeichnet sich durch eine besondere Einfachheit in Verbindung mit einer optimalen Verstellbarkeit aus. Sie besteht nur aus zwei Teilen und erlaubt trotzdem eine Justierung in bis zu drei Raumebenen.The holding device according to the invention is characterized by a particular simplicity in conjunction with an optimal adjustability. It consists of only two parts and still allows adjustment in up to three spatial levels.
Vorteilhafterweise ist das erste Halterteil stufenförmig gekröpft. Dadurch entsteht ein Freiraum, der insbesondere für die Schraubbefestigung des zweiten Halterteils benutzt werden kann.Advantageously, the first holder part is step-shaped cranked. This creates a free space that can be used in particular for the screw fastening of the second holder part.
Um eine Schraubverbindung zu ermöglichen, können die Öffnungen im ersten Halterteil als Gewindebohrungen ausgebildet sein. Alternativ bietet sich die Verwendung von Schweißmuttern an.In order to enable a screw connection, the openings in the first holder part may be formed as threaded bores. Alternatively, the use of weld nuts offers.
Für die Befestigung des Abgaskrümmers bietet sich eine gabelförmige Ausgestaltung des freien Endes des zweiten Halterteils an.For the attachment of the exhaust manifold, a fork-shaped configuration of the free end of the second holder part offers.
Anhand der Zeichnung soll die Erfindung in Form eines Ausführungsbeispiels näher erläutert werden.Reference to the drawing, the invention will be explained in more detail in the form of an embodiment.
