Abstract
Description
Die Erfindung betrifft ein Gehäuse für eine Hubkolben- Brennkraftmaschine nach dem Oberbegriff des Patentanspru ches 1.The invention relates to a housing for a reciprocating piston Internal combustion engine according to the preamble of claim ches 1.
Bei einem von Zugankerschrauben zusammengehaltenen Gehäu se einer Brennkraftmaschine sind vor der Bearbeitung der Lagerbohrung für die Kurbelwelle die Lagerdeckel der Kur belwellen-Hauptlager mit den Zugankerschrauben auf den Lagerhalbschalen des Gehäuses zu befestigen. Dazu ist als Gegenlager für die Zugankerschrauben eine Dummy-Platte anstelle des Zylinderkopfes aufzusetzen, damit im Gehäuse während der Lagerbearbeitung gleiche Spannungsverhältnis se wie bei einer montierten Brennkraftmaschine vorliegen. Das Aufsetzen der Dummy-Platte vor der Bearbeitung und das Entfernen nach der Bearbeitung ist in einer Großseri enfertigung sehr aufwendig.With a casing held together by tie bolts se an internal combustion engine are before processing the Bearing hole for the crankshaft the bearing caps of the cure main shaft bearing with the tie bolts on the To fix the bearing half shells of the housing. This is as Counter bearing for the tie bolts a dummy plate instead of the cylinder head, so in the housing same tension ratio during bearing processing se as with an assembled internal combustion engine. Put on the dummy plate before processing and the removal after processing is in a large series production is very complex.
Mit DE 196 04 547 A1 ist ein Gehäuse beschrieben, bei dem die Zugankerschrauben zweigeteilt sind. Jeweils zwei zu sammengehörende Hälften greifen in Gewindehülsen ein, die im Zylinderkurbelgehäuse eingegossen sind. Für die Bear beitung der Lagerbohrung der Kurbelwellenlagerung können so die Lagerdeckel mittels der unteren Teile der Zug ankerschrauben am Zylinderkurbelgehäuse befestigt werden. Eine Dummy-Platte als Ersatz für den Zylinderkopf ist da bei nicht erforderlich. Nachteilig ist jedoch, daß sich die Zugankerschrauben nicht über ihre ganze Länge gleich mäßig dehnen können, da sie an den Gewindehülsen unter brochen und gegenüber dem Gehäuse festgelegt sind.DE 196 04 547 A1 describes a housing in which the tie bolts are divided into two. Two each matching halves engage in threaded sleeves that are cast in the cylinder crankcase. For the Bear Machining the bearing bore of the crankshaft bearing can so the bearing cover by means of the lower parts of the train anchor screws are attached to the cylinder crankcase. A dummy plate to replace the cylinder head is there at not required. The disadvantage, however, is that the tie bolts are not the same over their entire length can stretch moderately because they are under the threaded sleeves broken and set against the housing.
Es ist auch bekannt (DE 44 13 255 A1), die integral mit dem Lagerstuhl gegossenen Lagerdeckel einer mehrteiligen Lageranordnung für die Kurbelwellenlagerung in einem Kur belgehäuse einer Brennkraftmaschine durch Bruchtrennen vom Lagerstuhl zu lösen, wobei die Trennflächen in zwei einen stumpfen Winkel einschließenden Ebenen verlaufen. Die Mittelachsen der Befestigungsschrauben der Lager deckel stehen senkrecht auf den winklig zueinander ange ordneten Trennflächen und schließen so ebenfalls einen Winkel ein, so daß eine durchgängige Anordnung von Zug ankerschrauben über die gesamte Motorhöhe nicht möglich ist.It is also known (DE 44 13 255 A1), which is integral with the bearing cap cast a multi-part bearing cover Bearing arrangement for crankshaft bearings in one course Bel housing of an internal combustion engine by breaking separation detach from the camp chair, the dividing surfaces in two planes enclosing an obtuse angle. The central axes of the mounting screws of the bearings Lids are perpendicular to the angled to each other arranged dividing surfaces and thus also include one Angle one, so that a continuous arrangement of train Anchoring over the entire motor height is not possible is.
Der Erfindung liegt die Aufgabe zugrunde, ein Gehäuse der eingangs genannten Art zu schaffen, welches im Motorbe trieb von durchgängig zwischen dem Zylinderkopf und den Kurbelwellen-Hauptlagern verlaufenden Zugankerschrauben zusammengehalten ist und bei dem für die Bearbeitung der Kurbelwellen-Hauptlager eine den Zylinderkopf ersetzende Dummy-Platte als Widerlager für die Zugankerschrauben nicht erforderlich ist.The invention has for its object a housing to create the type mentioned, which in the engine drifted continuously between the cylinder head and the Tie rod bolts running on the crankshaft main bearings is held together and for which the processing of The main crankshaft bearing replaces the cylinder head Dummy plate as an abutment for the tie bolts is not required.
Erfindungsgemäß wird diese Aufgabe durch die kennzeich nenden Merkmale des Patentanspruches 1 gelöst.According to the invention, this object is characterized by nenden features of claim 1 solved.
Durch die erfindungsgemäße Kombination ist ein Gehäuse für eine Hubkolben-Brennkraftmaschine geschaffen, welche die Vorteile aufweist, die sich durch die über die gesam te Gehäusehöhe verlaufenden vorspannbaren Zugankerschrau ben ergeben, ohne daß die Nachteile einer solchen Bauwei se bei der Bearbeitung der Kurbelwellen-Hauptlager auf treten. The combination according to the invention is a housing created for a reciprocating piston internal combustion engine, which has the advantages of being over the whole te height of the pre-tensionable tie bolt ben result without the disadvantages of such Bauwei se when machining the crankshaft main bearings to step.
Besonders vorteilhaft ist es, wenn die beim Bruchtrennen entstehenden Bruchflächen annähernd in einer senkrecht zu den Mittelachsen der Zugankerschrauben verlaufenden Ebene liegen, da dadurch die von den Zugankerschrauben aufge brachte Spannkraft ohne seitliche Komponente von den La gerdeckeln auf die Lagerhalbschalen des Lagerstuhls über tragen wird.It is particularly advantageous if the break separation resulting fracture surfaces approximately in a perpendicular to the plane of the center axis of the tie bolts lie, as this will open up the tie bolts brought resilience without side components from the La cover the bearing half shells of the storage chair will wear.
Ein Ausführungsbeispiel ist nachstehend anhand einer Zeichnung beschrieben. Die Zeichnung zeigt einen Schnitt durch ein erfindungsgemäßes Gehäuses einer Hubkolben- Brennkraftmaschine.An exemplary embodiment is based on a Drawing described. The drawing shows a section by an inventive housing of a reciprocating piston Internal combustion engine.
Das Gehäuse besteht im wesentlichen aus einem Zylinder kurbelgehäuse 1 und einem Zylinderkopf 2. Das Zylinder kurbelgehäuse 1 ist mit Lagerhalbschalen 3 versehen, die zusammen mit auf den Lagerhalbschalen 3 aufsitzenden La gerdeckeln 4 Kurbelwellenlager bilden. Der Zylinderkopf 2, das Zylinderkurbelgehäuse 1 sowie die Lagerdeckel 4 sind mittels durchgängiger Zugankerschrauben 5 miteinan der verspannt.The housing consists essentially of a cylinder crankcase 1 and a cylinder head 2 . The cylinder crankcase 1 is provided with half-shells 3 , which together with the bearing half-shells 3 seated La gerdeckeln 4 crankshaft bearings. The cylinder head 2 , the cylinder crankcase 1 and the bearing cap 4 are miteinan braced by means of continuous tie bolts 5 .
Das Zylinderkurbelgehäuse 1 ist nach unten durch eine Öl wanne 6 verschlossen.The cylinder crankcase 1 is closed by an oil pan 6 .
Das Zylinderkurbelgehäuse 1 mit seinen Lagerhalbschalen 3 sowie die Lagerdeckel 4 sind als integrales Gußteil her gestellt und werden als solches mechanisch bearbeitet, wobei auch die Lagerbohrung 7 der Kurbelwellenlager bear beitet wird. Erst nach der Bearbeitung der Lagerbohrung 7 werden Lagerdeckel 4 von den Lagerhalbschalen 3 durch Bruchtrennen abgetrennt. Für die Bearbeitung der Lager bohrung 7 ist es somit nicht erforderlich, die Lager deckel 4 mittels der Zugankerschrauben 5, welche sich dann über eine Dummy-Platte anstelle des Zylinderkopfes 2 abstützen müßten, zu halten. The cylinder crankcase 1 with its bearing half-shells 3 and the bearing cover 4 are made as an integral casting and are machined as such, with the bearing bore 7 of the crankshaft bearing being processed. Only after machining the bearing bore 7 are the bearing caps 4 separated from the bearing half-shells 3 by breaking separation. For the machining of the bearing bore 7 , it is therefore not necessary to keep the bearing cover 4 by means of the tie bolts 5 , which would then have to be supported via a dummy plate instead of the cylinder head 2 .
Die zwischen den Lagerhalbschalen 3 des Zylinderkurbelge häuses 1 und den Lagerdeckeln 4 verlaufende Bruchfläche 8 verläuft in einer Ebene, die annähernd senkrecht zu den Mittelachsen der Zugankerschrauben 5 liegt. Damit wird die Spannkraft der Zugankerschrauben 5 ohne seitliche Komponente von der Lagerdeckeln 4 auf die Lagerhalbscha len 3 des Lagerstuhls des Zylinderkurbelgehäuses 1 über tragen.The between the bearing half-shells 3 of the Zylinderkurbelge housing 1 and the bearing caps 4 extending fracture surface 8 extends in a plane which is approximately perpendicular to the central axes of the tie bolts 5 . So that the clamping force of the tie bolts 5 without lateral component from the bearing caps 4 to the Lagerhalbscha len 3 of the bearing block of the cylinder crankcase 1 carry over.
