Definitions

  • the present invention relates to a rail vehicle with at least two bogies and a method for coupling bogies of a rail vehicle.
  • a rail vehicle for mass transit which consists of at least 3 articulated car bodies.
  • Each car body has in each case a chassis, which are set, for example via a hydraulic control system in relation.
  • the DE 196 54 862 A1 also relates to a rail vehicle for mass transit with several interconnected car bodies.
  • Each car body has in each case a chassis, wherein hydraulic actuators are provided for the rotation of the car body relative to the bogie.
  • a rail vehicle for mass transit having a plurality of articulated interconnected, each rotatably supported on an associated chassis in the horizontal direction car bodies and a hydraulic sequence control of the deflection of the car bodies in response to the tracking.
  • the advantage of the hydraulic coupling is that it is preferably a completely passive system. Therefore, no sensor, active control or monitoring is absolutely necessary. It can also be mounted easily and safely and has reliable and robust operating characteristics. As a result of the hydraulic coupling, the respective bogies can thus be turned counter to one another, so that a very good reduction in the quasi-static wheel transverse forces in the wheel-rail contact is achieved. Only by the hydraulic coupling already vibrations due to the inertia of the hydraulic medium are damped and it is possible to filter out disturbing relative movements.
  • connection is thus made such that a turn to the right on a bogie leads to a left turn on the other bogie. This results in a coupling of the turnout angle of both bogies relative to the locomotive body or locomotive frame.
  • the two bogies rotate in opposite directions.
  • the method of the two cylinders can be matched to each other, while the necessary method of the cylinder can also be determined solely by which deflection the first cylinder experiences by entering the curve.
  • the hydraulic means comprise at least one line connecting the bogies.
  • advantageous arrangements are conceivable in which when entering the first bogie in the curve in the first Hydraulic cylinder hydraulic medium is displaced such that via the connecting line of the second hydraulic cylinder is actuated such that the second bogie is rotated in opposite directions to the first bogie by the second hydraulic cylinder.
  • the hydraulic cylinders communicating via the connecting line thus do not require any further control since the necessary deflection already results from the deflection of the first hydraulic cylinder as a result of the curve passage.
  • a hydraulic bias of the hydraulic means can be achieved by means of a storage unit.
  • the storage unit can be used for filling and / or refilling the system.
  • the maximum pressure in the coupling system can be limited by the storage unit.
  • a further embodiment consists in that the coupled bogies each have at least two actuating cylinders interconnected crosswise.
  • the coupled bogies each have at least two actuating cylinders interconnected crosswise.
  • the hydraulic means may have at least one pressure relief valve for overload protection. This makes it possible to limit the maximum transmission forces of the coupled bogies.
  • the pressure limiting valve By the pressure limiting valve, the differential pressure between the two piston surfaces is limited within the actuating cylinder, which is why their set pressure is directly proportional to the actuating force of the actuating cylinder.
  • load peaks can be better absorbed, which in turn has a positive effect on the life of the entire system.
  • the hydraulic means of the track-guided vehicle or of the rail vehicle have at least one buffer cylinder.
  • it can be set, for example, that smaller deflections of an actuating cylinder have no influence and forces are to be transmitted only when a threshold value is exceeded.
  • the transmission behavior of the coupling system can thus be adjusted by the buffer cylinder with regard to its transmission stiffness.
  • a defined force is adjustable, which remains under influence up to this force, the buffer cylinder without influence and the transmission stiffness of the hydraulic means is reduced when this force is exceeded.
  • a defined force is adjustable, by means of the at least one buffer cylinder a defined force is adjustable, already below this force reduces the transmission stiffness of the hydraulic means by means of several force thresholds and / or a multi-stage spring characteristic becomes.
  • the hydraulic means have at least one rolling damper. Basically, there is an oscillating Auswindterrorism by the wheel-rail contact, not by the Coupling the bogies is caused. Due to the roll damper function locomotives are able to dampen oscillating boring movements of the bogies in straight ahead driving. Thus, instabilities can be counteracted and the overall driving behavior can be improved.
  • the rolling damper is carried out by additional valves in the at least one line connecting the actuating cylinder. This has the consequence that in a vehicle that already has rolling-damper, the constructive or installation cost for retrofitting or production of the coupling system according to the invention is low.
  • the hydraulic means comprise oil as a hydraulic medium.
  • Oil uses a fluid as a hydraulic medium, which has low compressibility, low temperature influence on viscosity, good compatibility with seals, good lubricating properties, high aging resistance and a high flash point.
  • the hydraulic means comprise nitrogen as a hydraulic medium.
  • the hydraulic coupling of the bogies can be provided as a hydraulic medium oil.
  • the hydraulic bias includes nitrogen as a hydraulic medium. Due to its inert properties, nitrogen is well suited for hydraulic prestressing. It is advantageous if the hydraulic preload is 18 bar. At this pressure, a sufficient bias can be achieved.
  • the invention relates to a method with the features of claim 13. Thereafter, it is provided bogies of a rail vehicle according to one of claims 1 to 12 to couple hydraulically.
  • the method has the feature that by means of a storage unit operated with nitrogen, the oil-operated coupling of the bogies is biased.
  • FIG. 1 schematically shows a hydraulic bogie coupling 10 according to the invention for a multi-function locomotive that can be used both in goods and in long-distance passenger transport.
  • the multi-function locomotive has two biaxial bogies 12, which are each rotatably mounted on the frame of the multi-function locomotive, not shown.
  • the hydraulic bogie coupling 10 can be biased.
  • the storage unit 40 operates with nitrogen and a bias pressure of 18 bar without oil at 20 ° C.
  • the pressure is delivered via pistons to the oil-filled lines 34.
  • the differential pressure between the two piston surfaces can be limited within the actuating cylinder 20.
  • a damping cylinder 60 is provided, which is also interposed as the pressure relief valve 50 in the connecting lines 32 and the function satisfies a buffer cylinder.
  • the damping cylinder 60 can be adjusted so that the transmission stiffness is reduced only after reaching a presettable and changeable force threshold. Before, the damping cylinder 60 has no influence on the transmission behavior.
  • the set pressure is 145 bar, which corresponds to a force threshold of 30 kN.
  • FIG. 2 the characteristic of the damping cylinder 60 is shown. At the axis designated x while the angular difference in Auswindwinkel between two bogies 12 of the hydraulic bogie coupling 10 of the invention for a multi-function locomotive is offered. At the axis designated y, the passive force is applied in the coupling.
