  • a common flywheel drive is assigned to the two flywheel arrangements of the two compressor roller areas. This drives one of the flywheel assemblies directly and the other of the flywheel assemblies via a planetary gear.
  • the use of the planetary gear ensures that even if the two compactor roller areas rotate at different speeds around the common compactor roller axis of rotation, for example when driving through curves, the two centrifugal mass arrangements of the compactor roller areas work in phase with one another, i.e. if a speed difference occurs, there is no phase shift in the Vibrational movement of the two flywheel mass arrangements and thus no phase shift in the vibrational movement of the compressor roller areas excited by these flywheel mass arrangements to carry out a vibrational movement occurs.
  • the CN 103603258B discloses a method with which it is intended to ensure that in a soil compactor, which has two compactor rollers that can be excited to carry out an oscillating movement, no beats occur that are caused by superimposition of the oscillating movements.

  • Such an adjustment of the phase offset P of the vibratory movements of the two vibratory compactor rollers 14, 16 can be carried out repeatedly during operation of the soil compactor 12 or, if necessary, continuously, for example as part of a control loop, in order to ensure in this way that with a changing operating condition or operating behavior of the soil compactor 12, for example with increasingly more compacted ground and corresponding change in the vibration behavior of the Vibration compressor rollers 14, 16, the occurrence of unwanted vibration excitations is avoided by vibration superposition.
  • phase offset P other than zero is shown, depending on the operating state of the soil compactor 12, for example also depending on the respective vibration amplitude of the vibration compactor rollers 14,16, a phase offset P not different from zero can also be advantageous for avoiding an unfavorable superimposition of the vibration movements .
