Abstract (en)
[origin: US6681433B1] A sweeping unit has a supporting frame and at least one motor-driven rotary brush which is rotationally mounted about an longitudinal axis thereof The supporting frame is provided with supporting wheels, and a distance of the wheels from the axis of the rotary brush is controlled by an adjusting device having at least one hydraulic adjusting cylinder and a control device. A supply cylinder is hydraulically connected to the at least one adjusting cylinder and has a piston, or other signalling component, connected to a metering device and/or distance measurement device. A signal from the metering and/or distance measurement device is connected to the control unit. A working area of the supply cylinder communicates hydraulically with the at least one adjusting cylinder and has a smaller cross-sectional surface area than that of the at least one adjusting cylinder. Alternatively, the piston of the supply cylinder is connected to a mechanical adjusting drive mechanism.
