SchwinghebelRocker arm
Die Neuerung betrifft einen aus Blech bestehenden geschweißten Schwinghebel für Fahrzeugachsen der einerseits mit einer Torsionsfeder und andererseixs mit einer Radachse verbunden ist.The innovation relates to a welded rocker arm made of sheet metal for vehicle axles on the one hand with a Torsion spring and other is connected to a wheel axle.
Schwinghebel für diese Achsen werden, da sie sehr hohen Beanspruchungen ausgesetzt sind, überwiegend als Schmiedestücke ausgeführt. Bekannt sind jedoch auch aus Blech hergestellte Schwinghebel die wesentlich leichter und weniger materialaufwendig sind.Rocker arms for these axes are used because they are very stressful are exposed, mainly executed as forgings. However, those made from sheet metal are also known Rocker arms that are much lighter and less expensive in terms of material.
ZwecKmäßig wird ein Blechschwinghebel aus zwei Halbschalen gefertigt, die miteinander verschweißt werden. Besonders bei gekröpften Schwinghebel η Gesteht das Problem darin, di2 beiden Halbschalen so zu formen, daß für die Schweißnaht eine einfache geometrische Form entsteht die sich für automatische Schweißverfahren eignet und darüber hinaus beide Schalen so zu fertigen, daß sie genau zusammen passen und ein gleichförmiger Luftspalt entlang der liärtstelle entsteht. Gerade um diese letztere Forderuxig zu erfüllen, sind aufwendige Tiefziehwerkzeuge sowie ein zusätzliches Beschneiden der Ränder der Halbschalen erforderlich. Der dadurch bedingte hohe Fertigungsaufwand macht im allgemeinen die Materialersparnis zunichte, so aaß nur bei sehr großen Stückzahlen hiervon Gebrauch gemacht wird.A sheet metal rocker arm is made from two half-shells, which are welded together. Especially with cranked rocker arms η the problem is that di2 both To shape half-shells in such a way that a simple geometric shape is created for the weld seam, which is suitable for automatic welding processes suitable and also to manufacture both shells so that they fit exactly together and a uniform air gap arises along the liärtstelle. Especially about the latter Requiring to meet are complex deep-drawing tools as well an additional trimming of the edges of the half-shells is necessary. The resulting high manufacturing costs generally make the material savings are nullified, so use is only made for very large quantities.
j! e Keuerung verm ^i'/. ^t- ή fisf?n innhen i^ertigungsaufwancL aaaurcn_, ';aß nicht v/ie bisher zwei an den Kanten aneinanderstoßende Halbsohalen entlang des Stoßes verschweißt werden, sondern daß ^aIbschalen Verwenoung finden die ineinandersteckbar sind, so daß ein Verschweißen entlang des Rannes der übergreifenden Halbschale möglich ist. Auch bei einfachen und kostengünstigen Prägeverfahren und ohne nachträgliches Beschneiden der Ränder wird dadurch erreicht, daß ein gleichmäßiger Luftspalt entlang der Verbin.υngsnaht entsteht. Durch die sich bildende Kehlnaht v/ird außeraem aas Versch\€ißen der beiden Halbschalen sehr erleichtert, jjamiζ ist auch bei verhältnismäßig niedrigen Stückzahlen eine einfache und damit preisgünstige Herstellung solcher Schwinghebel möglich.j! e Kerung verm ^ i '/. ^ t- ή fisf? n inhen i ^ ertigungsaufwancL aaaurcn_, '; ate not v / ie hitherto two half-brackets butting at the edges have been welded along the joint, but that there are peelings used that can be plugged into one another, so that welding along the channel the overarching half-shell is possible. Even with simple and inexpensive embossing processes and without subsequent trimming of the edges, the result is that a uniform air gap is created along the connecting seam. By the forming fillet v / ill außeraem aas Misc \ € of the two half-shells Issen very relieved jjami ζ is possible such rocker also at relatively low volumes a simple and cost-effective production.
Vorzugsweise bilden die Kanten der Halbschalen G-erade oder Kreisabschnitte, so daß bei aer Herstellung des neuerungsgemäßen Schwinghebels auch automatisches Schweißverfahren eingesetzt werden kann. Zweckmäßigerweise werden hierbei, zur weiteren Erleichterung des Schweißens, alle Kreisabschnitte nach außen gekrümmt.The edges of the half-shells preferably form straight lines or circular segments, so that an automatic welding process is also used in the manufacture of the rocker arm according to the invention can be. Appropriately here, for further Ease of welding, all circle sections curved outwards.
Die Verbindung mit der Radachse ist bei derartigen Schwinghebeln dadurch schwierig, daß üblicherweise die Achsbolzen auc vergütetem, nicht schväSbäreffi Material "bestehen. 1VcIi der Neuerung wird diese Schwierigkeit dadurch ausgeräumt, daß die Halbschalen durch eine Rohrhülse verbunden sind, die nicht nur zur Steifigkeit des Schwinghebels beiträgt, sondern in die auch der Achsbolzen eingerpesst v/erden kann.The connection with the wheel axle is thereby difficult in such a rocking levers that usually auc the axle tempered do not exist schväSbäreffi material. "1 VCII the innovation is eliminated this problem in that the half-shells are connected by a pipe sleeve of not only the stiffness The rocker arm also contributes, but into which the axle bolt can also be grooved.
üie Neuerung ist schematiech auf der Zeichnung dargestellt und zwar zeigen:The innovation is shown schematically on the drawing and although show:
Fig. 1 eine Seitenansicht des Schwinghebels, Fig. 2 einen Längsschnitt nach II-II der Fig. 1 und Fig. 3 einen Querschnitt nach III-III der Fig. 11 shows a side view of the rocker arm, FIG. 2 shows a longitudinal section according to II-II of FIG. 1 and FIG. 3 shows a cross section according to III-III of FIG. 1

Der Scihv/T nahebei nnoh der Neijerimg 13t gebildet aus zwei ineinandersteckbare ^albschalen 1, 2 die entlang der Kante der Halbeschale 2 miteinander verschweißt sind. Zur Aufnahme einer Radachse ist einseitig eine Rohrhülse 3 eingeschweißt. Jenseits ist im Schwinghebel ein unrunder Ausschnitt 4 vorgesehen, zur Aufnahme einer Torsionsfeder bzw. zum Einfügen in eine Drehstabfederachse oder eine Gummifederachse für Fahrzeuganhänger.The Scihv / T near the Neijerimg 13t formed from two nested ^ alb shells 1, 2 which are welded together along the edge of the half shell 2. A tubular sleeve 3 is welded on one side to accommodate a wheel axle. Beyond that, a non-circular cutout 4 is provided in the rocker arm to accommodate a torsion spring or to insert it into a torsion bar spring axle or a rubber spring axle for vehicle trailers.
Aus der Seitenansicht ist ersichtlich, daß die Schweißnaht lediglich aus nach äußren gekrümmten Kreisabschnitten und diese Kreisabschnitte tangierenden Geraden gebildet wird, so daß sich diese Form sehr gut für das Verschweißen auf Schweißautomaten eignet.From the side view it can be seen that the weld seam consists only of outwardly curved circular segments and these Circle sections tangent straight lines is formed, so that this shape is very good for welding on automatic welding machines suitable.
