  • this object is achieved according to the invention in that a lever on a second pivot bearing is arranged on the base so that it can pivot about a second pivot axis, that the lever is articulated on the rocker and that a deflection element for the pulling element is attached to the lever is arranged, wherein the pulling element is guided in the load section on the deflection element.
  • the floor cleaning machine according to the invention can be used to clean textile floors and in particular carpeted floors, with smooth floors or hard floors basically also being possible to clean.
  • Hard floors or smooth floors are, for example, tiled floors, parquet floors, industrial screed floors, asphalt floors, cobblestones, PVC floors, etc. Different carpets can have different pile heights. Different floors can fundamentally require different contact pressures of the brush roller on the floor to be cleaned for effective cleaning.
  • an automatic regulation for a cleaning process and in particular for a contact pressure of the brush roller on the floor to be cleaned is realized via the pivotally arranged lever.
  • the motor device exerts a corresponding tensile force on the load section (tension section or load strand or tension strand) in order to drive the rotation of the brush roller.
  • the action of the roller brush on the floor to be cleaned creates a counter-torque, which results in a force in the load section or in a resulting tensile stress in the load section.
  • the resulting tensile stress for a given roller brush depends on the condition of the floor to be cleaned.
  • the contact pressure is automatically adjusted depending on the floor condition and it results an optimized cleaning result. It is automatically controlled and adapted to the respective soil conditions without an operator having to intervene.
  • the lever is articulated on the rocker via a third pivot bearing so as to be pivotable about a third pivot axis.
  • the lever can be used to act on the rocker in a simple manner in order to specify its pivot position on the first pivot bearing.
  • a simple structural design results if at least one of the following is provided: the axis of rotation and the first pivot axis are oriented parallel to one another; the axis of rotation and the second pivot axis are oriented parallel to one another; the first pivot axis and the second pivot axis are oriented parallel to each other; the axis of rotation and/or the first pivot axis and/or the second pivot axis lie transversely and in particular perpendicularly to a forward travel direction of the floor cleaning machine; the axis of rotation and/or the first pivot axis and/or the second pivot axis lie parallel to a wheel axis of the floor cleaning machine; the axis of rotation and/or the first pivot axis and/or the second pivot axis lie transversely and in particular perpendicularly to a vertical direction on the base, a position of the sweeping roller in the vertical direction being adjustable via a pivot position of the rocker on the first pivot bearing.

  • the third pivot axis is oriented parallel to the axis of rotation and/or parallel to the first pivot axis and/or parallel to the second pivot axis.
  • the first pivot bearing is positioned at a distance from the pivot bearing in relation to a longitudinal direction of the rocker. As a result, contact pressure adjustment can be made possible in a structurally simple manner.
  • first pivot bearing is positioned between the pivot bearing and the third pivot bearing in relation to a longitudinal direction of the rocker.
  • a pivoting position about the second pivoting axis specifies a pivoting position of the rocker about the first pivoting axis and in particular specifies at least one of the following: a height position of the broom to the base; a contact pressure of the brush roller on a floor to be cleaned; a width with which the sweeping roller acts on a floor to be cleaned.
  • the lever is arranged and designed in such a way that, during a cleaning operation in which the brush roller acts on a floor to be cleaned, a resulting force in the load section (tension section, load strand) of the tension element causes the lever to pivot into position is set at the second pivot bearing, the resultant force in the load section being determined by a torque of the brush roller on the floor to be cleaned. Due to the reaction force or the reaction torque of the brush roller when it acts on the floor to be cleaned, there is a resultant force in the load section, which leads to an adjustment of the pivoting position of the lever and thereby in turn to a corresponding adjustment of a pivoting position of the rocker on the first pivot bearing leads. This in turn allows a control process to be carried out in order to keep the sweeping roller in a position that is advantageous for effective cleaning or, in particular, to bring it into an advantageous position when changing floors.
  • a positioning device is provided via the traction mechanism for positioning the sweeping roller on a floor to be cleaned via the rocker, the positioning including automatic control via the lever.

  • the automatic control process can be switched on or off in this way.
  • the intermediate web has a smaller length between an articulation point on the second web and an articulation point on the rocker than a length of the second web between an articulation point on the first web and the articulation point on the intermediate web.
  • a toggle lever with a dead center position can be implemented in a simple manner.

  • a mechanical switch can be implemented in a simple manner in order to block or release the automatic control (via the pivoting mobility of the lever about the second pivot axis).
  • a dead center position of the toggle lever allows the at least one first position of the switch (or of the intermediate web) to be achieved in a simple manner and in a structurally simple manner.
  • the deflection element is seated on the first web.
  • the resulting tensile stress in the load section of the pulling member can be used to position the first web in a specific pivoted position relative to the base (on the second pivot bearing), this pivoted position depending on the nature of the floor to be cleaned. This in turn allows the pivoting position of the rocker to be specified on the first pivot bearing.
  • the rocker when the pivoting movement of the lever is blocked by the switch, the rocker is mounted in an oscillating manner on the base and thus the brush roller is also mounted in an oscillating manner on the base.

  • the rod is arranged in the area of a front end of the base in relation to a forward travel direction of the floor cleaning machine. In particular, there is an optimized use of space on the floor cleaning machine. This allows the rod to be positioned outside of a dirt guide path, a suction unit, etc., for example.
  • the traction mechanism is designed on one side in relation to the sweeping roller. This minimizes the number of components required. No synchronization and the like has to be provided.
  • the traction mechanism comprises a traction element tensioner, which is arranged in an empty section of the traction element.
