  • the lifting devices 5A, 7A assigned to the front and / or rear right hand drives 5, 7 in the working direction A are extended when the second distance value b determined by the second distance measuring device 17 is greater than the predetermined distance value b should , and the The lifting devices 5A, 7A assigned to the front and / or rear, right hand drives 5, 7 in the working direction A are retracted when the second distance value b determined by the second distance measuring device 17 is smaller than the predetermined distance value b should .
  • the front and rear lifting devices 4A, 5A, 6A, 7A can each be retracted or extended by the same amount if the distance sensors are at the level of the longitudinal axis 18 in the middle between the front and rear drives 4, 5, 6, 7 arranged milling drum 9 lie.
  • the desired milling depth is maintained across the width of the machined road section. Since the roadway 20 is wider than the milling track, in the present exemplary embodiment it is approximately twice as wide as the milling track, section 20B on the inside of the road still has to be machined.
  • the leveling device 15 provides a different leveling mode for processing this section. This leveling mode corresponds to the known leveling, in which a distance measurement is carried out on the end faces of the milling drum 10 on both sides of the road milling machine. Consequently, use can be made of the first distance measuring device 16 which is designed such that its reference point R1 lies in the working direction A on the left side of the milling drum 10.
  • the leveling device 15 again generates the control signals for the lifting devices 4A, 6A of the front and / or rear left drives 4, 6.
  • the leveling device 15 in the present embodiment cannot make use of the second distance measuring device 17. This distance measuring device 17 can therefore be deactivated or need not be present (installed).
  • the control signals for the front and / or rear, left and right lifting devices 4, 5, 6, 7 are now generated by a leveling device 15, which will be described below. Since the leveling mode again provides two distance measuring devices 16, 17 for the inside of the road, these distance measuring devices are again referred to as first and second distance measuring devices 16, 17.
  • the leveling device 15 for the inside of the carriageway 20B can be provided by the leveling device for the outside of the carriageway 20A described above, if the distance sensor 17A of the second distance measuring device 17 on the right in the working direction A of the machine frame 3 at a predetermined distance c from the distance sensor 16A first distance measuring device 16 is arranged.
  • the distance sensors 16A, 17A can be designed as interchangeable units that can be attached to suitable holders, so that the road milling machine can be equipped with suitable distance sensors for the respective leveling mode. However, it is also possible to provide three distance measuring devices or at least three distance sensors on the road milling machine 1, of which only two distance measuring devices or distance sensors are activated for the respective leveling mode.
  • the distance measurement is carried out on the right machine side with an optical distance sensor 17A '( Figures 4 and 5 ).
  • the distance measurement on the right side of the machine can also be done with the right edge protection and a cable pull sensor, which is already available on the left and right side in the known road milling machines.
  • the control and arithmetic unit 21 is configured for the leveling mode in the left-hand section of the road on the inside 20B in such a way that the lifting devices 4A, 6A of the front and / or rear, left-hand drives 4, 6 are retracted when that of the first distance measuring device 16
  • the first distance value determined is greater than the predetermined distance value, and the lifting devices 4A, 6A of the front and / or rear left drive 4, 6 are extended when the first distance value determined by the first distance measuring device 16 is smaller than the predetermined distance value.
  • the lifting devices 5A, 7A of the front and / or rear right-hand drives 5, 7 are retracted if the second distance value determined by the second distance measuring device 17 'is greater than the predetermined distance value, and the lifting devices 5A, 7A of the front and / or the rear, right drives 5, 7 are extended when the second distance value determined by the second distance measuring device 17 'is smaller than the predetermined distance value.
  • the inside of the road 20A can be processed.
