  • the size of this contact force is significantly influenced by the friction between the contact strips and the contact wire, the rigidity of the overhead line, the local or temporary geometry changes due to different contact wire heights, zigzag laying of the contact wire, wear of the contact strip and contact wire, different aerodynamic influences due to changing direction of travel and vehicle shapes, wind and vehicle speed, vibration behavior of the pantograph and the contact wire as well as change in flow speed in oncoming traffic in tunnels.
  • DE-A 30 33 449 describes a two-stage scissor pantograph with an upper pair of scissors, which is attached to the contact line via the pantograph rocker and is regulated with respect to this constant contact force first control device assigned to the upper scissors, a control device which emits control signals to keep the contact force constant and a second control device assigned to the second main scissors.

  • the main scissors are no longer locked and their position is continuously controlled so that the travel of the upper scissors is kept constant on average.
  • Actuating signals for the second actuating device assigned to the main scissors are then formed from the deviation of these actual values from a target value which corresponds to the desired time average of the actuating path of the first actuating device assigned to the upper scissors. If the travel is changed in one direction, the upper scissors are first adjusted to keep the contact force to the overhead contact line constant, and then the main scissors are readjusted to such an extent that the original value of the travel of the first actuating device is reached again.
  • the hydraulic servomotors of this well-known teaching complicate the design and are ultimately the reason why this two-stage pantograph pantograph could not prevail in practice.

  • the second insulator is arranged in the area of the trailing edge of the air flow, it is not inconsiderably involved in the still very high sound level of the entire pantograph construction.
