| The invention relates to a rail wheel comprising a wheel body and an outer wheel part, for example a wheel rim (1), and to a method for producing the same. The hardness profile of the wheel rim bearing surface on a newly-manufactured wheel varies across the breadth of said bearing surface, with a minimum degree of hardness in the middle area. This variable hardness profile evens out during travel as the middle area is strain-hardened. As a result, the rail wheel is more resistant to wear. | ||||||

Die Erfindung betrifft ein Rad für ein Schienenfahrzeug und ein Verfahren zur Herstellung desselben. Um ein Rad zu schaffen, bei dem trotz guter Bogenlaufeigenschaften eine hohe Stabilität bei hcher Geschwindigkeit gewährleistet ist und das auf durchschnittlich verschlissene Schienenprofile abgestimmt ist, ist vorgesehen, daß das Profil des Rades mit einem Profilauslauf an der Radaußenseite, einer aus einem konvexen und darauffolgenden konkaven Teil bestehenden gekrümmten Lauffläche und einem Spurkranz an der Radinnenseite mit einer gegenüber der Horizontalen um zumindest 65° geneigten äußeren Spurkranzflanke an das durchschnittliche Profil einer Schiene, dessen Krümmungs- und Steigungsverlauf ermittelt wird angepaßt wird, in der Art, daß das Profil des Rades in jedem Punkt eine absolut kleinere Krümmung als jene des Schienenprofils vorzugsweise mit stetig zunehmendem Abstand zu größeren Werten des Tangens der Steigung hin. Das erfindungsgemäße Radprofil wird nicht durch Funktionssegmente beschrieben, sondern durch Integration des Funktionsverlaufes der Profilkrümmung in Abhängigkeit der Profilsteigung generiert. Das Profil ist durch einen stetigen Krümmungsverlauf charakterisiert, wodurch gleichmäßige Berührungsverhältnisse beim Rad/Schiene-Kontakt resultieren. |

| The invention relates to heavy-duty solid wheels and tyres for rail locomotives and trucks made of forged, rolled, fully tempered alloyed steel. From known wheel breakages and the subsequent materials examinations to discover the causes of the damage it has been concluded that it may be attributed to the inadequate toughness properties of prior art grades of steel. A novel Cr-Ni-Mo steel has therefore been developed which, after special heat treatment, exhibits a manifestly greater potential toughness than, for example, R7 steel to the UIC code and in which, above all, the risk of wheel breakage after lengthy braking is reduced. | ||||||
