Definitions

  • the invention relates to a method and an apparatus for Mastery of horizontal restoring forces on the secondary springs of rail vehicle undercarriages.
  • a bogie In addition to the wheel springs on the individual wheels of a chassis of rail vehicles, usually a bogie the vehicle body or other structures of the rail vehicle opposite each chassis, parallel on bogies to the vertical axis of the bogie, with springs, so-called Secondary springs, supported. Usually on everyone Side of a bogie two or three coil springs between Bogie and vehicle body arranged. Also known are supports with air springs.
  • the lower or upper spring seat to make the secondary springs pivotable about an axis.
  • Different stiffnesses in longitudinal and Transverse direction of the vehicle body can be reached so that the restoring forces are absorbed in the lateral direction.
  • the restoring moment is due to the remaining in the longitudinal direction Powers only reduced.
  • DE-A 203 10 98 also discloses the deflection of the To limit secondary springs and thus the restoring forces, by placing the lower or upper spring seat on a sliding surface is guided laterally movably and with one on the bogie and vehicle body restrained linkage becomes. Here, too, restoring forces remain in the longitudinal direction of the vehicle body.
  • the invention is based on the object of specifying a solution with which the deflection movement between chassis and rail vehicle floor control better than before and minimizes the influence of restoring forces of the secondary springs becomes.
  • the seat of the secondary springs conveniently on the vehicle floor side, so shifted that the turning movement of the undercarriage is met.
  • the size of the adjustment can be made by the turning angle can be determined, which in turn from Curve radius of the track depends.
  • the adjustment of the spring seats takes place via actuators, either directly from the Angle of rotation of the chassis or controlled by one for it suitable electronics that provide information about the current Processed curve radius.
  • the system is with corresponding redundancies in the control and the provision of auxiliary energy for the actuators equipped and designed so that the spring seats in the event of total failure of the actuators, automatically neutral means for straight-ahead running.
  • Fig. 1 is a body 1 of a rail vehicle a bogie 2 with two wheelsets 3 shown schematically.
  • the rail vehicle is said to be cornering are on a track 4, which means that the bogie 2 turns out opposite the body 1.
  • the body 1 is supported on the bogie 2 via so-called secondary springs 5.
  • the secondary springs are 5 drawn here lying on the paper plane. Indeed stand them vertically on the bogie 2 (see Figure 2).
  • the lower ones move (bogie side) spring seats 6 opposite the upper one (Vehicle body side) spring seats 7, so that one of the Twist counteracting restoring torque results.
  • This Restoring torque is now counteracted according to the invention by the upper spring seats 7 are longitudinally movable in a bearing 8 are stored on the car body 1.
  • the movement of the upper spring seats 7 is controlled by means of actuators 9 so that the turning movement is balanced at least in the direction of travel and the upper spring seats 7 in this direction if possible stand exactly above the lower spring seats 6.
  • the coercive force the secondary springs 5 on the bogie 2 is at least reduced so that the flange start is counteracted becomes.
