Description

Bereich der TechnikField of engineering

Die Erfindung betrifft den Radantrieb des Fahrzeuges, vor allem des Schienenfahrzeuges, mit der niedrigen ungefederten Masse des Radantriebs. Der Radantrieb des Fahrzeuges ermöglicht die Erstellung des durchlaufenden Niederflurs vom Fahrzeug, besonders bei den Straßenbahnfahrzeugen.The invention relates to the wheel drive of the vehicle, especially the rail vehicle, with the low unsprung mass of the wheel drive. The wheel drive of the vehicle allows the creation of the continuous low-floor of the vehicle, especially in the tram vehicles.

Bisheriger Stand der TechnikPrevious state of the art

Bei den bekannten direkten elektrischen Radantrieben ist der elektrische Motor insofern mit dem angetriebenen Rad direkt verbunden, und dadurch vergrößert der elektrische Motor das ungefederte Gewicht des Fahrzeuges, was negative dynamische Auswirkungen auf Fahrzeug/Fahrweg bei der Fahrzeugfahrt hat. Die bisherige Radantrieb-Anordnung der Schienenfahrzeuge verhindert oder schränkt den durchlaufenden Niederflur des Schienenfahrzeuges zu Erstellen ein.In the known direct electric wheel drives, the electric motor is in this case directly connected to the driven wheel, and as a result the electric motor increases the unsprung weight of the vehicle, which has negative dynamic effects on the vehicle / track during vehicle travel. The previous wheel drive arrangement of rail vehicles prevents or limits the continuous low floor of the rail vehicle to create a.

Erfindungscharakteristikinvention characteristic

Die genannten Mängel beseitigt in großem Maße der Radantrieb des Fahrzeuges, vornehmlich des Schienenfahrzeuges, das den elektrischen Motor mit den Permanentmagneten enthält. Die Charakteristik des Radantriebes vom Fahrzeug besteht darin, dass unter der Rad-Außenseite der elektrische Motor im abgefederten Teil des Fahrzeugs festgehalten ist. Der Läufer des elektrischen Motors kann als Innenläufer oder Aussenläufer ausgeführt werden. Der Läufer wird mit dem Rad durch die flexible Radial- und Axial-Ausgleichskupplung oder durch die flexible Winkel- und Axialausgleichskupplung verbunden. Die Radial- und Axial-Ausgleichskupplung kann mit der Lenkerkupplung gebildet werden. In manchen Fällen ist vorteilhaft, im Innenläufer des elektrischen Motors eine Höhle zu erstellen. In dieser Läuferhöhle ist die flexible Winkel- und Axial- Ausgleichskupplung spielaufgebaut. Diese Ausgleichskupplung kann z. B. mit der ausziehbaren Gelenkwelle, der Lamellenkupplung, der Zahnkupplung oder der Kupplung mit den Gelenken aus den Gummikeil-Blöcken gebildet werden.The above shortcomings largely eliminate the wheel drive of the vehicle, especially the rail vehicle, which contains the electric motor with the permanent magnets. The characteristic of the wheel drive of the vehicle is that under the wheel outside of the electric motor is held in the sprung part of the vehicle. The rotor of the electric motor can be designed as an internal rotor or external rotor. The rotor is connected to the wheel through the flexible radial and axial balancing clutch or through the flexible angular and axial balancing clutch. The radial and axial compensation coupling can be formed with the handlebar coupling. In some cases, it is advantageous to create a cavity in the internal rotor of the electric motor. In this runner cavity, the flexible angle and axial compensation coupling is play-built up. This compensating coupling can z. B. with the extendable propeller shaft, the multi-plate clutch, the toothed clutch or the coupling with the joints of the rubber wedge blocks are formed.

Die individuell und gerade angetriebene Fahrzeugräder durch die elektrischen Motoren mit den Permanentmagneten bilden den Fahrzeugantrieb ohne Radsatz und weiter damit, dass die elektrischen Motoren auf der Außenseite des Fahrzeugs platziert sind, wird der Raum im Innern des Fahrzeuges freigesetzt. Dies ermöglicht den durchlaufenden Niederflur des Schienenfahrzeuges im Fahrgastraum zu gestalten. Der elektrische Motor, der im abgefederten Teil des Fahrzeugteils gegenüber dem Rad befestigt ist, herabsetzt das ungefederte Gewicht des Fahrzeuges. Der abgefederte Fahrzeugteil ist z. B. mit dem Drehgestellrahmen, dem Fahrzeughauptrahmen, dem Fahrzeugkasten oder dem Hilfsrahmen ausgeführt.The individual and just driven vehicle wheels by the electric motors with the permanent magnets form the vehicle drive without wheelset and further with the fact that the electric motors are placed on the outside of the vehicle, the space is in Interior of the vehicle released. This allows to make the continuous low floor of the rail vehicle in the passenger compartment. The electric motor, which is mounted in the sprung part of the vehicle part opposite the wheel, reduces the unsprung weight of the vehicle. The sprung vehicle part is z. B. executed with the bogie frame, the vehicle body frame, the vehicle body or the subframe.

Beispiele der ErfindungsdurchführungExamples of Invention Implementation

Der Radantrieb des Fahrzeuges besteht aus Rad 1, das auf der Achse drehbar gelagert ist. Vor der Außenseite des Rads 1 wird der elektrische Motor festgehalten, dessen Läufer 3 der Innen- (Bild 1 und 4) oder Außenläufer (Bilder 2, 3 und 5) sind. Der elektrische Motor wird gegenüber dem Rad 1 auf der abgefederten tragenden Grundkonstruktion des Fahrzeuges, die z. B. mit dem Drehgestellrahmen, dem Hauptrahmen des Fahrzeuges, dem Fahrzeugkasten oder dem Hilfsrahmen gebildet werden kann, festgehalten. Infolgedessen, dass der elektrische Motor in der Konstruktion festgehalten ist, die relativ gegenüber dem Rad 1 mittels der Auffederung abgefedert ist, kommt es zwischen dem Läufer 3 des elektrischen Motors und dem Rad 1 zu wechselseitigen Relativbewegungen. Die Auffederung kann z. B. mit den Stahlwickelfedern oder den Blattfedern, den Metallgummi-Elementen, dem pneumatischen System, dem hydraulischen System, dem hydropneumatischen System u.ä. versehen werden. Das Drehmoment aus dem Läufer 3 des elektrischen Motors wird in zwei Richtungen (Traktion/ Bremsung) auf das Rad 1 mittels der Ausgleichskupplung 2 übertragen. Die Ausgleichskupplung ermöglicht das Drehmoment auf das Rad 1 bei der gleichzeitigen Verformung der Ausgleichskupplung 2 in der Radial- und Axialrichtung oder der Winkelund Axialrichtung zu übertragen.The wheel drive of the vehicle consists of wheel 1, which is rotatably mounted on the axle. Before the outside of the wheel 1 of the electric motor is held, the rotor 3 of the inner (Figure 1 and 4) or external rotor (Figures 2, 3 and 5). The electric motor is relative to the wheel 1 on the sprung supporting basic structure of the vehicle, the z. B. can be formed with the bogie frame, the main frame of the vehicle, the vehicle body or subframe held. Due to the fact that the electric motor is held in the construction which is sprung relative to the wheel 1 by means of the springing action, mutual relative movements occur between the rotor 3 of the electric motor and the wheel 1 . The Auffederung can z. As with the steel coil springs or the leaf springs, the metal rubber elements, the pneumatic system, the hydraulic system, the hydropneumatic system, etc. be provided. The torque from the rotor 3 of the electric motor is transmitted in two directions (traction / braking) to the wheel 1 by means of the compensating coupling 2 . The balancing clutch enables the torque to be transmitted to the wheel 1 in the simultaneous deformation of the balancing clutch 2 in the radial and axial directions or the angular and axial directions.

Die Ausgleichskupplung 2, die mit den die Verformungen in der Winkel- und Axialrichtung ermöglichenden Elementen, ausgeführt wird, sind z. B. die ausziehbare Gelenkwelle, die Lamellenkupplung, die Zahnkupplung, und Kupplung mit den Gelenken aus den Gummikeil-Blöcken. Folgendermaßen entwickelte Ausgleichskupplungen 2 sind beim elektrischen Motor mit dem Innenläufer 3 (Bild 1) oder dem Außenläufer 3 (Bilder 2 und 3) verwendet. Im Läufer 3 ist die Höhle konzentrisch hergestellt, in der mit dem Spiel die Ausgleichskupplung 2 geordnet ist. Im Falle der Verwendung der Ausgleichskupplung 2, die Radial- und Axialverformungen ermöglicht, die z. B. die 5-Element-Pleuelkupplung mit den Parallelarmen, die homokinetische 9-Element- Pleuelkupplung mit drei Ringen u. ä. bilden, kann der Innenläufer 3 ohne Höhle (Bild 4), oder Außenläufer 3 (Bild 5) ohne Höhle sein. Die individuelle gerade Verbindung des Rads 1 mit dem Läufer 3 des elektrischen Motors setzt durch die Ausgleichskupplung 2 ohne die Verwendung der Übersetzung und ohne den Radsatz das ungefederte Gewicht des Radantriebes vom Fahrzeug herab, womit die dynamische Auswirkungen des Fahrzeuges bei der Fahrt verbessert werden. Die Erfindung ermöglicht weiter den durchgehenden Niederflur im Fahrgastraum, vor allem bei den Straßenbahnen zu bilden.The compensating coupling 2 , which is performed with the deformations in the angular and axial direction enabling elements are, for. B. the extendable propeller shaft, the Multi-plate clutch, the gear coupling, and coupling with the joints of the rubber wedge blocks. The following developed compensating couplings 2 are used in the electric motor with the internal rotor 3 (Figure 1) or the external rotor 3 (Figures 2 and 3). In the runner 3 , the cave is made concentric, in which the clearance 2 is arranged with the game. In the case of using the compensating coupling 2 , which allows radial and axial deformations, the z. B. the 5-element connecting rod coupling with the parallel arms, the 9-element homokinetic connecting rod coupling with three rings u. form the inner rotor 3 without a cave (Figure 4), or external rotor 3 (Figure 5) without a cave. The individual straight connection of the wheel 1 with the rotor 3 of the electric motor sets by the compensating clutch 2 without the use of the translation and without the wheel set the unsprung weight of the wheel drive from the vehicle, thus improving the dynamic effects of the vehicle while driving. The invention further enables the continuous low floor in the passenger compartment, especially in the trams to form.
