Abstract
A road milling machine having a milling roller with a plurality of chisels. A signal receiving unit is assigned to a machine component which is directly or indirectly involved in the milling process or to another machine component. The signal receiving unit detects an operating condition of the machine component and is connected to a signal emitting unit. An optical detecting device may be assigned to the road milling machine, whereby operations are made easier and the milling pattern is optimized.
Claims20
A road milling machine for stripping traveled surfaces by a milling roller having a plurality of chisels, wherein a signal pickup unit is assigned to at least one machine component involved in a work process, wherein the signal pickup unit detects an operational status of the machine component, the signal pickup unit is connected to a signal output unit via a signal processing arrangement having a machine frame (10) supported by a running gear (11, 12), at least one drive motor is assigned to the running gear, the machine frame (10) is supported at least in some areas by at least one adjustment device (20), and the machine frame (10) can be height-adjusted at least in some areas by the adjustment device (20) for assigning a fluid under pressure to the adjustment device (20), the road milling machine comprising:
- the drive motors designed as hydraulic motors, and the signal pickup unit detecting pressure fluctuations of a hydraulic pressure in the fluid of the drive motor or of the adjustment device (20), and
- the signal processing arrangement comparing a detected fluctuation image of the pressure fluctuations to a homogeneous fluctuation image of a milling roller with the chisels in an unworn state and displaying deviations between the homogeneous fluctuation image and the detected fluctuation image with a signal output arrangement.
