  • Such a relative mobility enables a vibration decoupling between the compressor roller 20 and the machine frame 22, which is of substantial importance in particular if an on in or in the compressor roller 20 Fig. 9 only schematically indicated device 26 is provided, with which a force or an acceleration can be exerted on the compressor roller 20, for example in order to Vertical direction V or in the circumferential direction to accelerate the roll axis of rotation.
  • Devices of this type to be used for generating a vibration acceleration or vibration movement and / or an oscillation acceleration or oscillation movement of the compressor roller 20 are sufficiently known in the prior art and need not be described in more detail.

  • the soil compactor 10 on the rear carriage also has a compacting roller and at least one of the compacting rollers is to be driven for rotation. If the soil compactor 10 has the in Fig. 9 Drive wheels 16 shown, it is not necessary to assign the compressor roller 20 itself a separate drive motor. Nevertheless, the drive motor for the device 26 described above can then be provided on or in the compressor roller 20 in order to drive unbalanced masses thereof for rotation about respective axes of rotation.
  • the suspension arrangement 28 comprises a roller support unit, generally designated 38, on which the compressor roller 20 is rotatably supported about the roller axis of rotation A, for example via the drive motor 36 or a bearing element provided on the roller disk 34.

  • the first carrier element 40 extends approximately in the vertical direction V, so that the fourth coupling region 56 and also the roll axis of rotation are positioned in the vertical direction V above the third coupling region 54. This means that even under the influence of gravity there is no significant tilting moment causing the first support element 40 to pivot with respect to the second support element 42. Rather, due to the fact that the machine frame 22 hangs on the compressor roller 20 via the two coupled support elements 40, 42, the roller support unit 38 will assume a state in which the two support elements 40, 42 correspond to one another in a state of minimal potential energy Relative swivel position.

This ensures that lateral forces, that is to say forces acting in the direction of the axis of rotation A of the roller, can also be transmitted between the compacting roller 20 and the machine frame 22, which can occur in particular when the soil compactor 10 is steered.
