Depending on the position of the adjusting moves the soil compacting device in the forward or reverse direction. Also in this soil compaction machine can only a forward or backward movement are set, each by the resulting Centrifugal force is determined in the end positions of the adjusting cylinder.

  • a pulse width modulation signal is periodic and has two states within the period, one first state and a second state. The ratio of the time duration during the first state is taken, to the period represents the duty cycle.
  • the pulse width modulation signal causes when driving the control valve that the adjusting cylinder during the first state in the direction of the first end position and during the second state towards the second end position emotional.
  • the adjusting cylinder does not take the respective end position directly, but moves to this during a certain period of time. If the state of the control valve changes according to a state change of the pulse width modulation signal so the adjusting cylinder then changes the Direction of the procedure if the previously desired end position has not yet been reached.
  • the Vibration direction of the vibrating machine is determined by the constant change of position of the vibrating machine Adjusting cylinder to an average.
  • the control valve By switching the control valve according to the pulse width modulation signal, it is so possible to reciprocate the adjusting cylinder between two positions during the period move.
  • the driving speed of the compacting machine results from the mean value the resulting from the respective positions of the adjusting cylinder speeds. It can thus the speed of travel relative to the end positions of the adjusting cylinder Driving speed can be reduced by the effective angle of inclination of the vibration direction is reduced with respect to the vertical direction of vibration.
  • the control unit can thus be connected to the control valve to the adjusting cylinder according to to control a first level of the pulse width modulation signal, so that the relative position of the imbalances be adjusted in the direction of a first fixed end position and the adjusting cylinder in accordance with a second level of the pulse width modulation signal, so that the relative position the imbalances are adjusted in the direction of a second predetermined end position.

  • the imbalance masses 2 are angularly offset to produce phase-shifted centrifugal forces arranged on the unbalanced shafts 1, so that depending on the relative position of the respective imbalances to each other, the resulting centrifugal force F more or less inclined to the vertical is.
  • Fig. 1 the resulting centrifugal forces at different relative positions of the imbalance masses 2 shown. It can be seen that the resulting centrifugal force depends on the relative positions of the imbalance masses 2 may be inclined to the vertical, with a movement in the direction of the horizontal Proportion of the resulting centrifugal force is effected.
