  • Patent number: 11976426
    Abstract: A soil processing machine, in particular a soil compactor, includes at least one drive roller and an electrohydraulic drive system for driving at least one drive roller. The drive system has a traction hydraulic circuit having at least one hydraulic motor and at least one hydraulic pump. The circuit includes a first line region between a first connection fitting of the at least one hydraulic pump and a first connection fitting of each hydraulic motor to drive the at least one drive roller in a first rotatable direction and a second line region between a second connection fitting of the at least one hydraulic pump and a second connection fitting of each hydraulic motor to drive the at least one drive roller in a second, opposite rotatable direction. A valve assembly is provided with each line region for selectively interrupting and releasing a fluid flow connection between the at least one hydraulic pump and at least one hydraulic motor.

  • Publication number: 20230160154
    Abstract: A soil processing roller for a soil processing machine includes a roller shell elongated in the direction of a roller axis of rotation and surrounding a roller interior and an unbalanced arrangement arranged at least partially in the roller interior. The unbalanced arrangement includes at least one unbalanced mass rotatable around an unbalanced axis of rotation having center of mass eccentric to the unbalanced axis of rotation and an unbalanced drive system having at least one unbalanced electric drive motor for driving the at least one unbalanced mass to rotate around the unbalanced axis of rotation. The at least one unbalanced mass is in an idle position when the unbalanced arrangement is deactivated, and the unbalanced drive system is designed, upon deactivation of the unbalanced arrangement, to operate the at least one unbalanced electric drive motor in an unbalanced return phase such that the at least one unbalanced mass is moved into the idle position.
