Abstract

The subject-matter of the invention is a connecting rod composed of fibre composite material for reciprocating piston machines, which is divided at the connecting rod head and is very slim. The division at the connecting rod head makes possible retrofitting on an undivided, multi-crank crankshaft. The division is achieved by the fact that the fibres loop around force introduction elements which are contained in the big end bearing cover and in the connecting rod. The force introduction elements are connected by clamping screws. The very slim construction is achieved by means of the cross-shaped course of the fibres in the shank of the connecting rod. It is thereby possible to make a substitution for installed metallic connecting rods in reciprocating-piston machines without structural modifications. The existing violin shape of the connecting rod is altered only insignificantly thereby. <IMAGE>

Description

Die Erfindung betrifft die Gestaltung einer Pleuelstange mitThe invention relates to the design of a connecting rod with

Pleueldeckel gemäß des Gattungsbegriffs des Patentanspruches.Connecting rod cover according to the generic term of the patent claim.

Die Pleuelstange und der Pleueldeckel bestehen zumindest teilweise aus faserverstärkten Werkstoffen und lassen sich im Wickel-, Pultrusions-, Tapelayiny-, Taperolling-, Preßverfahren usw. fertigen. Als Fasern kommen Metall-, Bor-, Glas-, Aramid-, Kohlenstoffasern oder heute noch unbekannte Produkte in Betracht.The connecting rod and the connecting rod cover exist at least partially made of fiber-reinforced materials and can be used in winding, pultrusion, tape-laying, Taperolling, pressing, etc. manufacture. The fibers used are metal, boron, glass, Aramid, carbon fibers or products that are still unknown today can be considered.

Diese Erfindung besitzt gegenüber anderen Erfindungen den Vorteil, daß die Pleuelstange und der Pleuellagerdeckel aus Faserverbundwerkstoff die gleichen äußeren Abmessungen haben, wie diejenigen aus einem herkömmlichen Werkstoff. Eine Pleuelstange mit Pleuellagerdeckel aus Stahl ließe sich somit ohne konstruktive Änderungen des Kurbeltriebes in den Motor einbauen.This invention has the advantage over other inventions that the connecting rod and the connecting rod bearing cap made of fiber composite material are the same have external dimensions, such as those made of a conventional material. One Connecting rod with connecting rod bearing cover made of steel could therefore be without constructive Install changes to the crankshaft drive in the engine.

Die Eigenschaften der Erfindung werden erreicht durch a) einen sehr schlanken Pleuelschaft, bei dem die Verstärkungsras rn teilweise kreuzförmig verlaufen b) einen teilbaren Pleuelkopf, bei dem im Formschluß Einlegeteile schlaufenförmig umschlungen werden und c) durch ein U-förmiges Querschnittprofil des Kolbenbolzenlagers, Pleuellagers und Pleuellagerdeckels, so daß die Steifigkeit der Lager gewährleistet ist.The properties of the invention are achieved by a) a very slim connecting rod shaft, in which the reinforcing tines run partially cross-shaped b) a divisible connecting rod head, in which the form-fitting insert parts are loop-shaped are wrapped around and c) by a U-shaped cross-sectional profile of the piston pin bearing, Connecting rod bearing and connecting rod bearing cap, so that the rigidity of the bearing is guaranteed is.

Bei einer Pleuelstange lassen sich die durch oszillierende Beweyungen hervorgerufenen Massenkräfte schlecht kompensieren, gut dagegen die durch rotatorisch hervorgerufene, so daß es sich anbietet, den Pleuelkopf u. U. vollständig aus Metall zu fertigen.In the case of a connecting rod, this can be achieved by means of oscillating Beweyungen Compensate poorly caused inertia forces, but well compensate for those caused by rotary caused, so that it is possible to make the connecting rod head completely made of metal to manufacture.

Hierfür lassen sich z. B. herkömmliche Pleuelkppfe verwenden, an die der Pleuelschaft mit Kolbenbolzenauge angearbeitet wird.For this purpose, z. B. use conventional connecting rods to the the connecting rod shaft is machined with a piston pin boss.

Eine Pleuelstange mit Pleuellagerdeckel, die vollständig aus Faserverbundwerkstoff gefertigt wird, müßte Lagerschalen aus Metall enthalten.A connecting rod with a connecting rod bearing cap made entirely of fiber composite material is manufactured, should contain bearing shells made of metal.

Die Pleuelstange besteht aus einem Zug- und Druckkörper. Der Druckkörper kann rohrförmig ausgebildet sein und sitzh innerhalb des Zugkörpers blinden. Der Druckkörper kann vollständig aus Faserverbundwerkstoff oder Metallhalbzeugen, die mit Hilfe von Faservcrbundwerkstoff fixiert werden, bestehen. Bei einem Druckkörper aus Metallhalbzeugen entfallen für den Druckkörper die Probleme des Kriechens der Kunststoffe bei höheren Temperaturen. LeerseiteThe connecting rod consists of a pull and push body. The pressure hull can be tubular and are blind inside the traction body. Of the Pressure hulls can be made entirely of fiber composite material or semi-finished metal products are fixed with the help of fiber composite material. With a pressure hull From semi-finished metal products, the problems of creep of the pressure hull do not apply Plastics at higher temperatures. Blank page
