Description
Radsatz für Schienenfahrzeuge Die Erfindung betrifft einen Radsatz für Schienenfahrzeuge, insbesondere schnellfahrende Schienenfahrzeuge.Wheel set for rail vehicles The invention relates to a wheel set for rail vehicles, especially high-speed rail vehicles.
Die für Laufwerke von Schienenfahrzeugen verwendeten Radsätze, die bekanntlich aus Achswellen mit Radscheiben, Radreifen und Bremsscheiben bestehen, sollen möglichst leicht gebaut sein, um die unabgefederten Nassen klein zu halten, damit die Schienen und der Oberbau möglichst wenig beansprucht und die Radreifen beim Rollen einem möglichst kleinen Verschleif? ausgesetzt werden.The wheelsets used for running gear in rail vehicles, the as is known, consist of axle shafts with wheel disks, wheel tires and brake disks, should be built as light as possible in order to keep the unsprung wetness small, so that the rails and the superstructure are stressed as little as possible and the wheel tires the least possible wear when rolling? get abandoned.
Trotz dieser Notwendigkeit des Leichtbaues muß jeder Radsatz beim Rollen unter den statischen und dynamischen Beanspruchunggen der im Betrieb auftretenden Kräfte ein größtmögliches Naß an sicherheit gegen Bruch aufweisen. Das wird in der Forderung nach ausreichender Dauerbiegewechselfestigkeit ausgedrückt.Despite this need for lightweight construction, every wheel set must be Roles under the static and dynamic loads that occur in operation Forces have the greatest possible degree of security against breakage. That will be in the Expressed the requirement for sufficient fatigue strength.
Wegen der mit der Rollbewegung ständig umlauf enden Beanspruchung am Radsatz kommt dieser Forderung eine entscheidende Bedeutung zu.Because of the constantly rotating stress with the rolling movement This requirement is of decisive importance on the wheelset.
Es ist bisher schon eine Reihe von Vorschlägen zur Minderung der Radsatzgewichte bekannt geworden. Diese Bemühungen laufen jedoch im wesentlichen darauf hinaus, stählerne Hohlachswellen, die beispielsweise durch Ausbohren von zunächst voll geschmiedeten Achsen hergestellt werden, und Radscheiben aus leichtmetall zu verwenden. Diese bekannten Konstruktionen weisen jedoch keine ausreichende Dauerbiegewechselfestigkeit auf.So far there have been a number of proposals for reducing the weights of the wheelsets known. However, these efforts essentially boil down to steel hollow axle shafts, for example by boring out initially fully forged Axles are made, and wheel discs are made of light alloy. These known constructions, however, do not have sufficient fatigue strength on.
Es is-t weiterhin bekannt, die Radscheibe entweder auf die Achswelle bei entsprechend hohem Radsitzübermaß aufzuschrumpfen oder aufzupressen, wobei erhebliche Spannungen in der Scheibe auftreten tind die Materialbeanspruchung aus dem elastischen Bereich in den plastischen verschoben werden kann. Zu diesen durch die Herstellung des Radsatzes bereits vorhandenen Beanspruchungen treten die durch den Fahrbetrieb auftretenden Belastungen, so daß also die vom Fahrbetrieb herkommenden Beanspruchungen relativ frÜh ihre Begrenzung finden.It is also known to either place the wheel disc on the axle shaft to shrink or press open if the wheel seat is overdimensioned, with considerable Tensions The material stress occurs in the pane can be moved from the elastic range to the plastic range. To this through the manufacture of the wheelset already existing stresses occur loads caused by driving, so that from driving originating stresses find their limitation relatively early.
Der Erfindung liegt die Aufgabe zugrunde, einen Radsatz der einleitend beschriebenen Art zu schaffen, dem die vorerwähnten Nachteile nicht anhaften, der vielmehr so ausgebildet ist, daß er bei voller Wahrung der erforderlichen Dauerbiegewechselfestigkeit gewichtsmäßig leichter auszuführen ist.The invention is based on the object of a wheel set of the introductory To create the type described, which does not adhere to the aforementioned disadvantages, the rather, it is designed in such a way that it fully maintains the required fatigue strength is easier to carry out in terms of weight.
Das wird erfindungsgemäß dadurch erreicht, daß zur Herstellung eines Leichtbauredsatzes, für insbesondere mit Höchstgeschwindigkeiten über 160 kg/h fahrende Schienenfahrzeuge, unter Wahrung der erfordsrlicher Dauerbiegewechselfestigkeit die Rader mit der Achse bei griLgem' Radsitzübermaß durch Metallklebung verbunden sind. Auf diese Weise gelangt man zu einem Radsatz für schnellfahrende Schienenfahrzeuge der die vorerwähnte Erfindungsaufgabe voll erfüllt. Hinzu kommt, daß wegen des geringen Radsitzübermaßes die Räder einen eigenspannungsarmen Zustand aufweisen, so daß sie bei gleicher Belastung geringere Abmessungen aufweisen und somit im Gewcht leichter werden.This is achieved according to the invention in that for the production of a Lightweight construction set, especially for those traveling at top speeds of over 160 kg / h Rail vehicles, while maintaining the required fatigue strength the wheels are connected to the axle at griLgem 'oversized wheel seats by means of metal bonding are. In this way one arrives at a wheel set for high-speed rail vehicles who fully fulfills the aforementioned task of the invention. In addition, because of the low Wheel seat oversize the wheels have a low residual stress state, so that they have smaller dimensions with the same load and are therefore lighter in weight will.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die Räder aus Radscheibe und Radreifen bestehen, wobei die Scheibe und der Reifen bei geringem Reifeniibermaß durch Metallklelbung miteinander verbunden sind. Auch hierdurch läßt sich der bisher übliche Eigenspannungszustand innerhalb der Radscheibe wesentlich senken.According to a further feature of the invention it is provided that the Wheels consist of a wheel disc and wheel tire, with the disc and the tire at small tire oversize are connected to each other by metal joints. Also because of this the previously customary internal stress state within the wheel disc can be significantly reduced reduce.
Vorteilhafterweise ist gemäß der Erfindung ein Radsitzübermaß von höchstens 0,4 %o und bei bereiften Bädern ein Reifensitzübermaß von höchstens 0,75 %o vorgesehen.Advantageously, according to the invention, there is a wheel seat oversize of a maximum of 0.4% o and, in the case of frosted bathrooms, a tire seat oversize of at most 0.75 % o provided.
Die Erfindung sieht weiterhin vor, daß die Räder als Vollräder mit vergleichsweise dünnem Felgenkranz mit oberflächenvergüteter Zone ausgebildet sind.The invention also provides that the wheels as solid wheels with comparatively thin rim with a surface-coated zone are formed.
Der zur Metallklebung verwendete Metallkleber ist erfindungsgemäß schlagT, schwingungs- und mikrobenfest.The metal adhesive used for metal bonding is according to the invention impact, vibration and microbe-proof.
Außerdem werden gemäß einem weiteren Erfindungsgedanken die üblichen und bekannten, auf der Achswelle angeordneten Achsbremsscheiben an das Rad als Radbremsscheiben gelegt, wobei die Befestigung am Felgenkrsnz beispielsweise durch Schrumpfen oder Metallkleben erfolgt, wodurch weitere Gewichtseinsparungen durch den entfall der Nabensitze und der Naben der Bremsscheiben gewonnen werden. Ferner entfällt die bei Achsbremsscheiben durch das Angreifen der Bremskräfte auf die Radsatzwelle, den Radsitzverband und die Radscheibe ausgeübte Torsionsbeanspruchung, so daß die Welle, der Radsatz und die Radscheibe wiederum gewichtsvermindert ausgeführt werden können.In addition, according to a further concept of the invention, the usual and known axle brake disks arranged on the axle shaft to the wheel as wheel brake disks placed, the attachment to the rim for example by shrinking or Metal gluing takes place, which further saves weight by eliminating the Hub seats and the hubs of the brake discs are obtained. Furthermore, the in the case of axle brake discs, by the braking forces acting on the wheelset shaft, the wheel seat association and the wheel disc exerted torsional stress, so that the Shaft, the wheel set and the wheel disc are in turn designed to be reduced in weight can.
Die Anbringung der Bremsscheibe am Rad erfolgt so, daß zusätzliche Beanspruchungen des Scheibenblattes aus der Bremsscheibenbefestigung auf ein Mindestmaß reduziert werden und solche aus der Bremserwärmung vollständig entfallen.The brake disc is attached to the wheel so that additional Stresses on the disc blade from the brake disc attachment to a minimum are reduced and those from the brake heating are completely eliminated.
In der Zeichnung ist ein iusführungsbeispiel der Erfindung dargestellt. Die Erfindung beschränkt sich nicht auf die dargestellte Ausfuhrungsform, vielmehr sind im Rahmen der Erfindung weitere Abweichungen möglich.The drawing shows an exemplary embodiment of the invention. The invention is not limited to the embodiment shown, rather Further deviations are possible within the scope of the invention.
Der in der Zeichnung dargestellte, erfindungsgemäß ausgebildete Radsatz findet Verwendung insbesondere bei schnellfahrenden Schienenfahrzeugen. Mit dem Radsitz 1 der Radsatzwelle 2 ist das Voll rad 3 bei vergleichsweise geringem Radsitzübermaß durch Metallklebung verbunden. Es empfiehlt sich, den Laufkranz 4 durch eine Oberflächenvergütung verschleißfest auszuführen.The wheelset designed according to the invention and shown in the drawing is used in particular in fast-moving rail vehicles. With the Wheel seat 1 of the wheelset shaft 2 is the full wheel 3 with a comparatively low wheel seat oversize connected by metal bonding. It is advisable to give the running ring 4 a surface finish wear-resistant.
In dem Felgenkranz 5 ist der Ring 6 eingeschrumpft, der über eine Vielzahl von Spannhülsen 7 die Bremsscheiben 8 mit ihren Kühlrippen 9 trägt.In the rim 5, the ring 6 is shrunk, which has a A large number of clamping sleeves 7 which the brake disks 8 carry with their cooling fins 9.
