  • a precise control is not ensured, then it is advisable to have one on the actuator or on the drive Provide position transmitter that an electrical position signal on the current Setting position delivers.
  • This position signal can then be used as an actual position value electrical comparison device are supplied, the quasi-static as a setpoint Output signal of the filter is supplied and from the setpoint and actual value each Control deviation to be compensated feeds the controller, its output signal as Control variable is output to the actuator until the control deviation at least approaches almost zero.
  • the sensor unit and in particular the filter can have two quasi-static ones Have signal outputs, with an actuator at each of these signal outputs is connected, the actuators together on the same drive and in particular act on its drive frame.
  • the mechanical points of attack of the two Actuators are in particular diagonally to one another and in the areas of Drive frame, in which there are secondary spring elements for connecting the drive frame with the assigned car body.
  • primary spring elements between the drive frame and the wheel bearings of the uniaxial wheel set.
  • the transverse rigidity of these spring elements causes the basic alignment of the drive in the vehicle's longitudinal axis and can be in operation limited deflection of the wheel set resulting from the wheel-rail geometry, while the displacement forced by the actuator against the force of Secondary spring elements takes place.
  • Expediently forms a pivot bearing a real vertical axis for the swiveling movement of the drive compared to the Car body.

  • the sensor unit 14 consists of an encoder sensor 17, which is the radius of one to be driven Track arc dependent origin signal, which depends on another, itself according to the wheel-rail geometry adjusting drive or to each other related angular position of car body parts of neighboring cars is generated. After these transmitter devices not only from the radius of the track to be driven but are also subject to interference, is the bow-dependent signal part an interference signal resulting from the vehicle dynamics is superimposed.
  • the sensor sensor 17 accordingly provides a dynamic original signal w (t) dyn, which a low-pass filter 18 with an upper cutoff frequency of up to 5 Hertz, but preferably only 0.5 Hertz is fed.
  • the shares of the faster, higher-frequency interference vibrations are thereby eliminated from the original signal, so that at the output of the filter 18, preferably two separate output connections for the two actuating units 15 has, in each case, a quasi-static reference variable w (t) which acts as a setpoint serves for the setting of the respective actuator 9.
