Definitions

  • the invention relates to an arrangement for transmitting longitudinal forces in a rail vehicle.
  • the hydraulic axle guide bearing for a rail vehicle described comprises a guide pin and at least one spring element which is arranged between the guide pin and a guide eye of an axle guide.
  • the spring element comprises a hydraulic bushing which has an outer housing and an inner housing.
  • the outer housing encloses the inner housing at a radial distance so that an annular gap is formed.
  • a (rubber) elastic element is arranged in the annular gap such that it at least partially delimits two diametrically opposed chambers, which are referred to as the first chamber and the second chamber, respectively.
  • the two chambers are filled with a hydraulic fluid.
  • the two chambers are connected to one another via an internally guided overflow channel.
  • the overflow channel achieves a fluid shift between the two chambers, so that a required low longitudinal stiffness is achieved when cornering and a required high stiffness when driving straight or without curves.
  • This setting also ensures low-wear and low-noise travel on curved tracks.
  • This optimized alignment of the wheelset is made possible by the hydraulic axle guide bearing, which must have the lowest possible longitudinal stiffness when cornering and very high stiffness when traveling straight or without curves.
  • FIG 5 shows two wheel sets RS1, RS2 of a rail vehicle, which are connected in a known manner to a bogie DGST of a rail vehicle via hydraulic axle guide bearings ALL1 to ALL4.
  • the first wheelset RS1 is connected to the bogie DGST via two hydraulic axle guide bearings ALL1 and ALL2, which have external connections and are designed as described above.
  • a first axle guide bearing ALL1 has two (diametrically) opposite chambers KAM11, KAM12, which are referred to as the first chamber KAM11 and the second chamber KAM12, respectively.
  • the second chamber KAM12 is arranged in front of the first chamber KAM11.
  • a second axle guide bearing ALL2 has two (diametrically) opposite chambers KAM21, KAM22, which are referred to as the first chamber KAM21 and the second chamber KAM22, respectively.
  • the second chamber KAM22 is arranged in front of the first chamber KAM21.
  • the first chamber KAM11 of the first axle guide bearing ALL1 is connected to the first chamber KAM21 of the second axle guide bearing ALL2 for fluid exchange via external connections.
  • the second chamber KAM12 of the first axle guide bearing ALL1 is connected to the second chamber KAM22 of the second axle guide bearing ALL2 for fluid exchange via external connections.
  • This fluid transfer is caused by a change in the relative position of the housing elements of the axle steering bearings ALL1, ALL2, which in turn is caused by the longitudinal forces.
  • the second wheelset RS2 is connected to the bogie DGST via two hydraulic axle guide bearings ALL3 and ALL4, which have external connections and are designed as described above.
  • a first axle guide bearing ALL3 has two diametrically opposed chambers KAM31, KAM32, which are referred to as the first chamber KAM31 and the second chamber KAM32, respectively.
  • the first chamber KAM31 is arranged in front of the second chamber KAM32.
  • a second axle guide bearing ALL4 has two diametrically opposed chambers KAM41, KAM42, which are referred to as the first chamber KAM41 and the second chamber KAM42, respectively.
  • the first chamber KAM41 is arranged in front of the second chamber KAM21.
  • the first chamber KAM31 of the first axle guide bearing ALL3 is connected to the first chamber KAM41 of the second axle guide bearing ALL4 for fluid exchange via external connections.
  • the second chamber KAM32 of the first axle guide bearing ALL3 is connected to the second chamber KAM42 of the second axle guide bearing ALL4 for fluid exchange via external connections.
  • the invention relates to an arrangement for transmitting longitudinal forces in a rail vehicle with a first and a second hydraulic axle guide bearing, with a wheelset and with a bogie of the rail vehicle.
  • Each axle guide bearing has an outer housing element and an inner housing element as well as a first and a second chamber filled with a fluid.
  • the two chambers are arranged opposite each other between the two housing elements, so that a change in the relative position of the inner housing element to the outer housing element causes an alternating change in the volume of the two chambers via a fluid exchange.
  • Each axle guide bearing has two external connections, with each chamber of the axle guide bearing being connected to one external connection.
  • Each axle guide bearing is connected to both the bogie and the wheelset via the associated housing elements in order to transfer longitudinal forces generated by the rail vehicle during travel between the wheelset and the bogie.
  • the longitudinal forces cause the relative position of the inner housing element to change to the outer housing element and thus the alternating volume change of the two chambers due to the exchange of fluid.
  • a first chamber of the first axle guide bearing is connected to a first chamber of the second axle guide bearing via a damping element for fluid exchange.
  • a second chamber of the first axle guide bearing is directly connected to a second chamber of the second axle guide bearing for fluid exchange.
  • the damping element also introduces or influences stiffness into the system.
  • the outer housing element of the axle guide bearing encloses the inner housing element at a radial distance, so that an annular gap is formed.
  • a (rubber) elastic element is arranged in the annular gap in such a way that it forms the two opposing chambers.
  • the first chamber in the axle guide bearing is connected to a first connection via a first channel that runs inside the inner housing element.
  • This first connection is arranged as part of the inner housing element in the outer area of the axle guide bearing.
  • the second chamber is connected to a second connection via a second channel that runs inside the inner housing element. This second connection is arranged as part of the inner housing element in the outer area of the axle guide bearing.
  • the damping element is designed as a cylinder filled with the fluid with an integrated piston.
  • the piston is arranged in such a way that the fluid of the first two chambers acting on the piston during the fluid exchange causes a dampened movement of the piston in the cylinder.
  • the cylinder has a total cylinder volume which is divided into a first cylinder partial volume and a second cylinder partial volume via the movably mounted piston, so that, depending on the direction of movement of the piston during the fluid exchange, an alternating Volume change of the first cylinder partial volume and the second cylinder partial volume occurs through the piston.
  • the first cylinder sub-volume is connected to the first chamber of the first axle guide bearing via an external connection, while the second cylinder sub-volume is connected to the first chamber of the second axle guide bearing via an external connection.
  • the stamp is coupled to a spring and a damper connected in parallel to dampen the movement of the stamp.
  • the spring and the damper set an intended damping which depends on the position of the stamp and/or its direction of movement.
  • the damping element is designed as a possibly adjustable line constriction, through which the movement of the fluid is dampened.
  • the present invention transforms unstable eigenmodes of the rail vehicle into stable eigenmodes.
  • the present invention enables increased driving speeds to be achieved with high levels of safety.
  • the present invention increases the driving stability of the rail vehicle.
  • the present invention uses the two lines to ensure that the damping element can be positioned at any location on the rail vehicle.
  • the present invention or the damping element connected via external lines makes it possible to advantageously arrange this damping element at a location with sufficiently large installation space and thus, if necessary, also away from the axle guide bearings.
  • the individual stiffnesses of the axle guide bearings and the individual dampings of the axle guide bearings as well as the damping in the hydraulic system result in an overall stiffness and an overall damping.
  • the present invention achieves suitable or optimal parameter ranges for stiffness and damping.

  • a (rubber) elastic element GEE is arranged in such a way that it forms two opposing chambers KAM1, KAM2 with respective chamber volumes.
  • the two chambers KAM1, KAM2 contain a fluid FLU and can be coupled to chambers of another axle guide bearing via the two external connections ANSCHL1, ANSCHL2 and the respective connecting lines LTG1, LTG2. This is described in FIG 3 described in more detail.
  • the first chamber KAM1 is connected to the first connection ANSCHL1 via a first channel KAN1, which runs inside the inner housing element GEHI.

  • the second connection ANSCHL2 is part of the inner housing element GEHI and is located in the outer area of the axle guide bearing ALL.
  • the change in the relative position of the two housing elements GEHI, GEHA is caused by longitudinal forces which arise when the rail vehicle is moving and are transmitted from a wheelset to the outer housing element GEHA, from this to the inner housing element GEHI and from this to a bogie of the rail vehicle.
