Abstract (en)

[origin: EP0843047A1] The sweeper comprises a rotatable, motor-driven roller brush raisable and lowerable by a lifter to different ground heights. On the lifter, a regulator acts with the ground distance of the roller brush as an adjustment. The regulating extent of the regulator is the drive torque for the roller brush or a proportional extent in relation to it. A signal representing the speed of the roller brush is connected to the regulating unit and this constitutes a speed-dependent theoretical value for the work torque for the roller brush. The roller brush is driven by a hydrostatic hydraulic motor and the hydraulic pressure for the hydraulic motor is the regulating entity for the regulating unit.
