Description
Achsbrücke für Nutzkraftfahrzeuge Die Erfindung bezieht sich auf eine Achsbrücke für Nutzkraftfahrzeuge, die aus mehreren miteinander verschweißten Teilen besteht. Axle bridge for commercial vehicles The invention relates to an axle bridge for commercial vehicles that are welded together from several Sharing consists.
AchsbrUcken von Nutzkraftfahrzeugen sind heute allgemein zylindrisohe Körper mit über die Länge veränderlichen Durchmessern und Wandstärken. Infolge der Abstützung des Aufbaues des Fahrzeuges über die Achsfedern auf der Achsbrücke und deren Abstützung über die Räder auf der Fahrbahn sind die Achsbrücken an Jedem Ende im Bereich zwischen Achsfeder und Rad w wenn Feder und Rad gemäß dem Regelfall in verschiedenen Falrzeuglängsebenen liegen - besonders stark beansprucht und müssen deshalb dort eine größere Wandstärke als im übrigen Bereich haben Bei Triebaohsen kommt dazu noch eine besondere Beanw spruchung der Achsbrücke im mittleren Bereich, wenn dort das Gehäuse des Achsgetriebes an der Achsbrücke angeflanscht wird.Axle brackets of commercial vehicles are generally cylindrical today Bodies with diameters and wall thicknesses that vary over their length. As a result of The superstructure of the vehicle is supported by the axle springs on the axle bridge and their support via the wheels on the roadway are the axle bridges at each end in the area between axle spring and wheel w if spring and wheel according to the rule in different longitudinal planes of the folding vehicle - particularly heavily used and must therefore have a greater wall thickness there than in the rest of the area there is also a special stress on the axle bridge in the middle area, if the housing of the axle drive is flanged to the axle bridge there.
Diesen Problemen trägt man bisher in der Weise Rechnung, daß die Achsbrücke aus mehreren Teilen zusammengesetzt wird. Bei einer solchen Lösung ist die Achsbrücke in ihrer Querrichtung (das ist die Fahrzeuglängsrichtung) in der Mitte geteilt, die beiden Hälften werden nach der Art von Kartuschen geschmiedet und nach dem Schmieden zusammengeschweißt. Dieses Verfahren ist sehr teuer.These problems have been taken into account so far in such a way that the axle bridge is composed of several parts. at such a solution is the axle bridge in its transverse direction (that is the longitudinal direction of the vehicle) in divided in the middle, the two halves are forged in the manner of cartridges and welded together after forging. This procedure is very expensive.
Nach einem anderen Verfahren besteht die Achsbrücke aus einem Achsmittelstück für den Anschluß des Gehäuses des Achsgetriebes und an dem Mittelstück beiderseitig angeschweißten Stummeln.According to another method, the axle bridge consists of an axle center piece for the connection of the housing of the axle drive and to the middle piece on both sides welded stubs.
Diese Stummel sind zur Aufnahme der Radlager bestimmt, während die Federlager an den Enden des Mittelstückes sich befinden.These stubs are intended to accommodate the wheel bearings, while the Spring bearings are located at the ends of the middle piece.
Das Mittelstück selbst besteht wieder aus zwei HaLbschalen, die in einer horizontalen Ebene miteinander verschweißt sind. Die Halbschalen sind aus Blech gepreßt und im Bereich des Anschlusses für das Gehäuse des Achsgetriebes durch aufgedoppeltes Blech verstärkt, während die Seitenstummel durch spanabhebende Verformung (Drehen) hergestellt sind. Das Aufdoppeln des Bleches ist ein zusätzlicher, kostenbringender Aufwand. Die Schweißnähte zwischen dem Mittelstück und den Seitenstummeln liegen in einem besonders hoch beanspruchten Bereich der Achsbrücke und geben deshalb leicht Anlaß zu Schäden. Die insgesamt vier Schweißnähte verteuern die Achsbrücke und fordern eine Nachbehandlung mit Glühen und Sandstrahlen, was weiter die Kosten der Achsbrücke erhöht.The middle piece itself consists of two half-shells, which are in a horizontal plane are welded together. The half-shells are off Pressed sheet metal and through in the area of the connection for the housing of the axle drive doubled sheet metal reinforced, while the side stubs by metal-cutting deformation (Turning) are made. The doubling of the sheet is an additional, costly one Expenditure. The welds lie between the center piece and the side stubs in a particularly highly stressed area of the axle bracket and therefore give easily Cause for damage. The total of four welds make the axle bridge more expensive and demand post-treatment with annealing and sandblasting, which further increases the cost of the axle bridge elevated.
Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden und eine Achsbrücke zu schaffen, die billig herzustellen ist und gute Festigkeitseigenschaften hat.The object of the invention is to avoid these disadvantages and a To create axle brackets that are cheap to manufacture and have good strength properties Has.
Zur Lösung der gestellten Aufgabe wird vorgeschlagen, daß insgesamt zwei aus Je einem Blech gepreßte Hälften in einer horizontalen Ebene durch Schweißen miteinander verbunden sind und die Ueber die Länge der Achsbrüoke unterschiedliche Wafldstärke durch Reckwalzen aus einem Flachmaterial mit ursprünglich gleicher Wandstärke hergestellt ist. Insbesondere sollen die beiden Brückenhälften aus ebenen Blechen, sogenannten Platinen hergestellt sein die zur Herstellung unterschiedlicher Wandstärken und der in die Ebene abgewickelten Kontur der beiden Hälften zunächst gegeneinander drehenden Profilwalzen durchlaufen und dann in einem Gesenk ihre räumliche Kontur, d.h. ihre Krünunung um die Brückenlängsachse erhalten haben.To solve the problem, it is proposed that a total of two halves each pressed from a sheet metal in a horizontal plane by welding are connected to each other and the over the length of the Achsbrüoke different Wafld thickness by forging rollers from a flat material with originally the same wall thickness is made. In particular, the two halves of the bridge should be made of flat sheet metal, so-called blanks are made for the production of different wall thicknesses and the contour of the two halves, developed into the plane, initially against each other going through rotating profile rollers and then their spatial contour in a die, i.e. have received their curvature around the longitudinal axis of the bridge.
Beim Redkwal2en werden unterschiedliche Wandstärken sowohl zu den Enden der Platine hin, als auch in der Mittelpartie erzeugt, um die zur späteren Befestigung des Achsantriebes notwendigen Querschnitte zu erzielen. Je nach Größe der für diese Verformung notwendigen Reckwalze kann die so hergestellte Platine über die ganze Spannweite der Achsbrücke reichend, aus einem Stück oder aus zwei gleichen Teilen bestehen, welche vor dem Verformen im Gesenk miteinander verschweißt werden.With Redkwal2en, different wall thicknesses are added to both the Ends of the board, as well as in the middle section, around the later Attachment of the final drive to achieve the necessary cross-sections. Depending on size the forging roll required for this deformation can be the blank produced in this way Reaching over the entire span of the axle bridge, from one piece or from two consist of the same parts, which are welded together in the die before being deformed will.
Mit der gekennzeichneten Lösung und ihren weiteren Ausgestaltungsmerkmalen ist eine Achsbrücke aufgezeigt, die einfach und billig herzustellen ist und festigkeitsmäßig gute Eigenschaften aufzuweisen hat.With the marked solution and its further design features an axle bridge is shown, which is easy and cheap to manufacture and in terms of strength has good properties.
Die Erfindung ist im folgenden an der Zeichnung näher erläutert. In der Zeichnung zeigen Fig. 1 die eine Hälfte einer Achsbrücke, oben als Schnitt und unten als Ansicht, Fig. 2, eine für die Herstellung einer Achsbrücke gem.The invention is explained in more detail below using the drawing. In The drawing shows Fig. 1, one half of an axle bridge, as above cut and below as a view, Fig. 2, one for the production of an axle bridge according to.
3 Fig. 1 durch Reckwalzen vorbereitete Platine in der Seitenansicht (Fig. 2) und in der DrauS-sicht (Fig. 3) Die Achsbrücke besteht aus den beiden symmetrischen Halbschalen 1, 2, die in der neutralen Fase zusammengeschweißt sind (Fig. 1)..Da die Schweißnaht 3 in der neutralen Fase der Achsbrücke liegt, muß die Schweißnaht 3 nach dem Zusammenschweißen der beiden Halbschalen weder geglüht noch anschließend gesandstrahlt werden. 3 Fig. 1 plate prepared by forging rollers in a side view (Fig. 2) and in the DrauS view (Fig. 3) The axle bridge consists of the two symmetrical ones Half-shells 1, 2, which are welded together in the neutral bevel (Fig. 1) .. There the weld 3 lies in the neutral bevel of the axle bridge, the weld must 3 after the two half-shells have been welded together, neither annealed nor subsequently to be sandblasted.
Jede Halbschale ist aus einem Flachmaterial als Ausgangswerkstoff hergestellt. Das geschieht im sogenannten Reckwalzverfahren, d.h. zwischen entsprechend profilierten Walzen. Damit ist die Kontur Jeder Brückenhälfte in die Ebene abgewickelt vorgeformt. Das damit vorgeformte Teil wifd mittels Pressen in einem entsprechenden Gesenk zur Halbschale geformt, d.h.Each half-shell is made from a flat material as the starting material manufactured. This happens in the so-called forging process, i.e. between accordingly profiled rollers. The contour of each half of the bridge is thus developed into the plane preformed. The part preformed with it is then pressed into a corresponding one Die formed into a half-shell, i.e.
um die Brückenlängsachse gebogen. Die Verstärkung 4 der Mittelpartie der bEwbrUcke für den Anschluß des Gehäuses des Achsgetriebes ist ebenfalls i Reokverfahren hergestellt. Vor dem Einlegen im Gesenk kann Jede Hälfte ihrerseits aus zwei miteinander verschweißten, einzeln gereckten Platinen zusammengesetzt worden sein.curved around the longitudinal axis of the bridge. Reinforcement 4 of the middle section the movement bridge for connecting the housing of the axle drive is also in the Reok process manufactured. Before being placed in the die, each half can be made up of two together welded, individually stretched blanks have been put together.
