Definitions

  • the invention relates to a self-propelled road milling machine according to the preamble of claim 1.
  • a disadvantage of this solution is that the milling drum drive hydrostatically by hydraulic motors are mounted on both sides of the milling drum.
  • the connection between the segments is a simple connector that allows only insufficient centering of the milling rotor. Characterized in that a drive device is provided on both sides, not close to the edge milling is possible.
  • a roll housing variable width is required, which is very expensive to construct.
  • US 4,720,207 describes mounted on a roll body Fräsrohrsegmente.
  • a corner ring segment is first attached to one side. Then the Fräsrohrsegmente are screwed to this, with the glands are within the segments.
  • a disadvantage is the enormous Verschraubungsaufwand and that the depth of cut is limited due to the constant diameter of the body, when a planetary gear is integrated into the body.
  • This gear arrangement with a gear whose outer diameter is only slightly smaller than that of the milling tube, is required to allow a flush milling.
  • a disadvantage of this solution is that to carry out various milling, such as normal or fine milling, a complete disassembly of the milling drum must be done. In a work application with maximum working width, i. if all segments are mounted, the individual segments then have different cutting circle diameters, so that the milled road surface milled in the transverse direction are staged.

  • the milling tubes must be almost flush with the zero side to allow a near-edge milling.
  • the arranged on the drive side gear would limit the feasible depth of cut.
  • the reduction gear is on the null side of the machine, i. on the side on which a near-edge milling is possible arranged.
  • the disadvantage here is that extending from the drive side to the reduction gear on the null side drive shaft is required, which must be stored, and must be provided with an additional protection tube against damage.
  • the reduction gear forms a fixed bearing, which must be arranged by the arrangement on the null side inevitably on the drive side a floating bearing.
  • a pivotable side plate for quick change of the milling tubes is arranged on the null side, which is less suitable to absorb the high reaction forces of a fixed bearing in the axial direction.
  • Another disadvantage is that the long drive shaft acts as a torsion suspension, whereby a rigid drive of the milling drum is not possible and the maximum possible cutting forces are reduced.

  • the circular-cylindrical housing of the reduction gear adapted in its cross-sectional shape to the support means for the milling tube can receive tubular or annular, undivided radial support means for the milling tube and / or protective devices for the housing over its entire axial length.
  • the seat for the support and / or protective devices may extend only to a part of the axial length of the preferably circular cylindrical housing.
  • the radial support means form a movable bearing on the preferably circular cylindrical housing for the milling tube.
