Definitions

  • the invention relates to a rail vehicle with variable axle geometry.
  • the cracks can also develop on the surface, grow in the depth and also lead to material eruptions, as happens for example in the known phenomenon of herringbone pattern.
  • surface-initiated cracks there is the effect that the cracks are in part removed by the mentioned profile wear, which implies that some degree of tread wear may be desirable can.
  • tread damage mentioned above there are a number of other types of damage such as flat spots, material application, tread cross cracks, etc.
  • the wheel-rail contact is therefore, for example, in high-speed trains, a special safety significance to. Irregularities in the wheel-rail contact, for example, by severe damage to a wheel, can lead to significant consequential damage to derailment. But even slight damage such as fine cracks can cause great difficulties, as they require maintenance work and thus can cause high costs and delays in train traffic.
  • EP 0 600 172 A1 a chassis for rail vehicles, in which the wheelsets are turned off during cornering by means of force-controlled actuators against the bogie frame.
  • no radial position of the wheelsets is realized relative to the track, but only the angle between the wheelset and chassis frame adjusted according to the radial position.
  • the DE 44 13 805 A1 discloses a self-steering triaxial drive for a railway vehicle in which the outer two sets of wheels are provided with a radial control and the inner wheel is movable by an active actuator transverse to the direction of travel.
  • the lateral forces are reduced to the réellerad accounts - with appropriate loading of the active actuator affects each wheel set one third of the centrifugal force.
  • all three wheelsets are used to control when cornering, the alignment of the wheelsets to the center of the arc is improved.
  • the invention is therefore based on the object of specifying a rail vehicle with variable axle geometry, which arbitrary, determined by a model-based method layers (angular position and transverse displacement) of the axes to each other while driving the rail vehicle and the required amount of actuators is minimized.
  • each axle of a rail vehicle is mounted horizontally angularly displaceable relative to the vehicle frame and can be changed continuously and independently of the other axles in its horizontal angular position by means of an associated actuator during operation of the rail vehicle, wherein the Angular position of each axis is specified by an optimization method.
  • the rail vehicle according to the invention, or the bogie according to the invention are particularly advantageous for the implementation of the method described in the non-prepublished application A942 / 2007 for optimizing the wear behavior, since the design complexity is greatly simplified by subject invention. Particularly important is the elimination of a structurally extremely complex so-called "Queraktuators".
  • the subject invention allows the use of structurally simple actuators (for example, hydraulic or pneumatic cylinders or electric actuators).
  • the method described in A942 / 2007 provides as output variables the angular position d ⁇ between two axes and the so-called transverse displacement dx. These two sizes can be adjusted with a rail vehicle according to the subject invention exclusively by setting certain horizontal angles of the axes to the vehicle frame, whereby a smooth running of the rail vehicle and an optimized wear behavior of the wheels is achieved.
  • each optimal values of the angular position d ⁇ and transverse displacement dx can be set, with only the horizontal angle of each axis to the vehicle frame is to be provided as variable.
  • the present invention allows the elimination of the structurally very complicated Queraktuatoren.
  • the so-called asymmetrical control according to the invention makes it possible, by means of the asymmetrical division of the angle d ⁇ between two axes, to two different ones Angle ⁇ 1 and ⁇ 2 make the targeted adjustment of the transverse displacement dx without having to provide an actuator for the transverse displacement.
  • a preferred embodiment of the invention provides to provide a fixed point (vertical pivot point) of each axis at one end of the axle and to assign an actuator which acts on the other end of the axle.
  • This actuator is mounted according to the invention mounted on one side at a fixed point of the vehicle frame and attached to a second side of the horizontal angularly displaceable mounting of the associated axle of the rail vehicle.
  • a further preferred embodiment of the invention provides that, on successive axes, the actuators assigned to them act alternately on opposite ends of the axles, so that, for example, on an axle whose actuator is arranged on one side of the rail vehicle, an axle drives its actuator on the opposite side of the axle Rail vehicle is arranged follows.
  • the advantage can be achieved to make optimum use of the available space in the chassis of the rail vehicle.
  • Other embodiments in which, for example, the actuators of all axes are provided on one side of the rail vehicle are also conceivable.
  • a particular embodiment of the invention provides, the axes of the rail vehicle as a so-called “loose gear” in which the wheels are mounted on a shaft (axis) and can rotate independently.
  • Another embodiment of the invention provides for the use of so-called “wheelsets” in which the wheels are fixedly connected to the axle.
  • the invention is well suited for use in a bogie of a railway vehicle.
  • Fig.1 shows by way of example and schematically the basic structure of a rail vehicle with variable axle geometry.
  • a rail vehicle S comprising two axes A1, A1 which are mounted horizontally rotatably about one pivot point at each end of each axis A1, A2.
  • an actuator AKT1, AKT2 engages, which is connected at its other end to the frame of the rail vehicle S.
  • Fig.2 shows by way of example and schematically the output variables of a model-based method for minimizing tread damage and profile wear. It is a rail vehicle with two axes A1 and A2 shown, which can assume any horizontal angular positions (axis angle d ⁇ ) to each other and which have a transverse displacement dx to each other.
  • the center distance L corresponds to the distance between the centers of the axes A1 and A2.
  • the effective axial distance dy since usually only very small axial angle d ⁇ occur, be approximately equated to the axial distance L.
  • the two parameters axis angle d ⁇ and transverse displacement dx are determined by means of a model-based method so that, inter alia, optimum wear behavior of wheels and rail profiles is achieved.
  • Figure 3 shows by way of example and schematically the determination of the horizontal angle of each axis, wherein the combination of the horizontal angle of the first axis ⁇ 1 and the horizontal angle of the second axis ⁇ 2 is determined from the predetermined sizes axis angle d ⁇ and transverse displacement dx.
  • Figure 4 shows by way of example and schematically the determination of the deflection of actuators in a rail vehicle according to fig1 ,
  • This in Fig.1 shown rail vehicle is equipped on each of the axes A1, A2, each with an actuator AKT1, AKT2, which attacks the end of each axis A1, A2.
