Definitions

  • the present invention relates to a soil compactor, which can be used, for example in road construction, to compact a prepared substrate or to compact the asphalt applied to the prepared and compacted substrate.
  • the CN 103603258 B discloses a method by which it is to be ensured that in a soil compactor which has two compressor rollers which can be excited to carry out a vibrational movement, no beats caused by superposition of the oscillatory movements occur.
  • the oscillation frequencies of the two compactor rollers excited for oscillation are detected and set in such a way that the occurrence of beats is largely avoided by a difference existing between these oscillation frequencies.
  • the compressor rollers of the soil compactor operated in this way are thus excited to carry out oscillatory movements with mutually different oscillation frequencies.
  • each flywheel mass drive comprises a drive motor, preferably a hydraulic motor, and that each flywheel mass arrangement comprises at least one flywheel driven by the associated drive motor for rotation about a flywheel rotation axis ,
  • the drive arrangement 52 can be formed separately from the drive arrangement 36, but linked to it for information exchange in order to be able to operate the two oscillation excitation arrangements 22, 24 in a coordinated manner.
  • the two drive arrangement 36, 52 can in principle also be combined in one and the same drive arrangement and designed to control both imbalance drives 30, 46.
  • the Fig. 3 shows in a schematic representation of the two vibrating compressor rolls 14, 16 with their associated flywheel assemblies 26 and 42.
  • the two rotating about the respective compressor roller axes A 1 and A 2 in rotation flywheels 28, 44 are shown so that they have an angular offset ⁇ to each other, but basically rotate in the same direction.
  • 16 detecting acceleration sensors 40, 56 acceleration signals B 1 , B 2 are generated, the course in Fig. 4 is shown.
  • the two vibration excitation assemblies 22, 24 are substantially identical to each other and basically the same, ie In particular, at the same speed of their flywheels 28, 44 are operated, the two acceleration signals B 1 and B 2 , which represent the time course of the accelerations of the vibrating compressor rollers 14, 16, the same frequency and substantially the same amplitude of acceleration , It can be seen, however, that, caused by the offset ⁇ of the two flywheel masses 28, 44, for example, reference can be made here to the angular position of the centers of mass of the respective flywheel masses 28, 44, a phase offset P is present.
  • the flywheel assemblies 26, 42 can be acted upon to influence the phase displacement P of the oscillatory movements caused by them in the two vibrating compressor rollers 14, 16 and thus to counteract such an undesired interference.
  • a phase offset with the value zero ie an in-phase vibration excitation of the two vibrating compressor rolls, unfavorable, so setting any non-zero phase offset can be interpreted as providing a predetermined phase offset in the context of the present invention.
  • a predetermined phase offset in the sense of the present invention can also be defined by a value range of the phase offset. It is important in the present invention in principle that at least one of the vibration excitation arrangements can be acted upon in order to be able to actively effect a change in the phase offset.
