Definitions

  • the invention relates to a cutting body for producing a lane marking with a rotation body rotatable about a rotation axis, which can accommodate a plurality of cutting elements, which define a cutting curve, wherein the cutting curve forms a convex cutting area in the direction of the axis of rotation.
  • the invention further relates to a roadway marking with a plurality of depressions introduced into the roadway surface, the depressions having two lateral longitudinal walls running in the longitudinal direction of the roadway, which proceed from the roadway surface into a floor area, and wherein the recess is bounded by two transverse walls extending transversely to the roadway longitudinal direction is.
  • road markings are also referred to as Wilsontelstsammlung.
  • a road milling machine with a cutting body which has a Fräswalzenrohr as a rotary body.
  • the roll surface is barrel-shaped and convex in the direction of the axis of rotation. It picks up chisel holders in which chisels can be exchanged.
  • the bits are equipped with carbide tips, which serve as cutting elements. Corresponding to the convex curvature of the roller surface, the carbide tips form a convex cutting curve in the direction of the axis of rotation of the milling roller tube. This convex cutting curve results during the rotation of the rotating body.
  • the rotating cutting body is delivered in the direction of the road surface to be processed, then the chisels cut a recess from the roadway.
  • a concave trough is generated transversely to the longitudinal extent of the roadway. Due to the circular cross-section of the body of revolution, the recess has a concave shape even in the longitudinal direction.
  • To produce a lane marking a plurality of depressions are milled from one another at equal pitch into the lane. The road marking thus forms a desired geometric unevenness in the road. When rolling over with a vehicle tire, noises and vibrations occur, which are perceived by the driver and signal him, for example, leaving the road.
  • the lane markings thus have the function and task of delivering an acoustic and haptic warning signal.
  • this noise source is sometimes disturbed by the environment adjacent to the roadway.
  • Another disadvantage of the known road markings results when driving over a two-wheeler.
  • the two-wheeler is laterally offset, which can then trigger dangerous steering corrections for the driver. If rainwater accumulates in the depressions, then the driving situation of the bicycle may become unstable.
  • the object relating to the cutting body is achieved by indirectly or directly adjoining the convex cutting area on both sides of a concave cutting area.
  • the task relating to the lane marking is achieved in that the longitudinal walls of the depressions have a convexly curved region.
  • depressions can be milled for road markings, in which the road surface is continuously transferred over the convex portion in the concave bottom.
  • the geometry of the lane marking also allows for a problem-free driving over a two-wheeler and that a nuisance in the driver's side is reduced.
  • the convex portion of the recess With the convex portion of the recess, the volume formed by the recess is reduced. Thus, it can collect less water, which significantly reduces the risk of instability of a two-wheeler on wet roads.
  • At least one of the concave cutting regions terminates at the end facing away from the convex cutting region in an end region parallel to the axis of rotation. In this way, a harmonious transition to the road surface is created in the depression, which withstands particularly robust mechanical stresses.
  • the radius of the convex cutting region is between 200 mm and 400 mm, and / or that the radius of the concave cutting region is between 400 mm and 800 mm, then corresponding geometries arise at the depression, which with reduced influence on the Tire guide cause sufficient noise.
  • a conceivable invention alternative is such that the rotary body has a mounting surface, are mounted on the tool holder, which can receive the cutting elements interchangeable, that the mounting surface has a convex cutting portion associated with the convex mounting portion and the concave cutting portion associated concave mounting portion.
  • the cutting curve can be generated in a simple manner using the same bit holder and cutting elements.
  • a cutting body according to the invention can be characterized in that a fastening flange is arranged in the hollow region enclosed by the rotational body and that the fastening flange is coupled to the rotational body at the inner wall section assigned to the convex cutting region.
  • the fastening flange is thus fixed in the strength-optimized manner in the thickened section of the rotational body formed by the convex cutting region.
  • the transverse walls have a concave area, which is indirectly or directly transferred to the road surface. Then arises when hitting the wheel on the transverse wall a sufficiently high sound pressure.
  • the depressions can to form the lane marking each other in the same Dividing grid be spaced or it is conceivable that the individual wells immediately adjacent.
  • FIG. 1 shows a cutting body having a roller-shaped rotary body 10.
  • the rotary body 10 is tubular and has a cylindrical inner receptacle which is formed by the jacket of the rotary body 10.
  • a mounting flange 11 is arranged with fastening receptacles 12, to which the output shaft of a drive train can be flanged.
  • the jacket of the rotary body 10 forms a support member 13 with a barrel-shaped circumferential mounting surface 14.
  • the mounting surface 14 is composed of a central convex mounting portion 14.2 and two laterally adjoining thereto concave mounting portions 14.1 together.
  • the concave fastening sections 14.1 pass directly into the convex fastening section 14.2.
  • On the two mounting portions 14.1 and 14.2 chisel holder changing systems, consisting of a base part and a replaceable fastened thereto bit holder 20, mounted.
  • the base parts are welded to the fastening sections 14.1, 14.2.
  • the base parts are offset from one another in the circumferential direction, so that clearing and loading turns result, which run helically on the fastening sections 14.1, 14.2.
  • bit holders 20 are welded directly onto the fastening sections 14.1, 14.2, so that base parts can be dispensed with.
  • the bit holder 20 have chisel recordings in which Chisel 21, preferably round shank chisel, can be interchangeable recorded.
  • the chisels 21 are equipped with cutting elements which define a cutting curve 15 when the rotation body 10 rotates about the axis of rotation R.
  • the cutting curve 15 forms a kind of envelope.
  • FIG. 1 illustrates the cutting curve 15 according to the configuration of the mounting portions 14.1, 14.2 a convex cutting area 15.2 and laterally adjoining concave cutting areas 15.1.
  • the radius R 1 of the concave cutting areas 15.1 is preferably between 400 mm and 800 mm.
  • the particularly preferred ratio R 1 : R 2 of about 2: 1 can be set.
  • lane markings consisting of depressions 31 arranged in a row one behind the other, can be cut into the carriageway 30.
  • the resulting geometry of the recess 31 is in FIG. 2 shown enlarged.
  • the depression 31 has, complementary to the cutting curve 15, a concave bottom 31.2 transversely to the roadway longitudinal direction, from which two convex longitudinal walls 31.1 rise on both sides.
  • the longitudinal walls 31.1 merge into the roadway surface 32.
  • the transversely extending to the roadway longitudinal extent transverse walls 31.3 are concave according to the roll circumference.
  • FIGS. 3 to 8 various design variants of road markings are shown, which are each formed of juxtaposed recesses 31.
  • the depressions 31 are produced by cutting bodies which, in principle, conform to the construction FIG. 1 correspond.
  • FIG. 3 shows an embodiment variant in which the cutting body delivered perpendicular to the road surface 32 and after the cutter body its deepest feed position has been restored before it is offset by the desired pitch in the roadway longitudinal direction, etc.
  • FIG. 4 shows one too FIG. 3 changed approach.
  • the cutting body is not reset above the level of the road surface 32, but continuously delivered during the feed movement along the roadway longitudinal direction to the deepest delivery position and returned to the level of the road surface, so that the recesses 31 are lined up directly.
  • the feed and reset movement can be coordinated with the feed motion in such a way that also produce an alternating arrangement of convex and concave curved areas of the recess in the roadway longitudinal direction. It can thereby be achieved that each individual depression of the series of recesses receives a similar curve in the longitudinal section, as the cross section.
  • FIG. 5a shows a cutting body 10 according to the prior art, which generates with its chisels 21 a cylindrical envelope. Accordingly, can be with this cutting body 10 road markings 31 milled with partially cylindrical geometry, such as FIG. 5b shows. That the FIG. 5b taken enlarged detail acc. FIG. 5c shows that results in this road markings 31 a sharp 90 ° transition between the road surface 32 and the subsequent longitudinal wall 31.1.
  • FIG. 6a shows a further cutting body 10 according to the prior art (for example according to the US 6,547,484 B2 ).
  • the chisels 21 produce a spherical cutting curve. This results in this cutting body 10 road markings 31 in FIG. 6b shown form.
  • FIG. 6c shows one of FIG. 6b taken detail. It can be seen that the transition from the road surface 32 in the longitudinal side walls 31.1 relative to the variant according to FIGS. 5b and 5c is significantly flattened, but still forms a relatively steep transition.
  • Figure 7a shows for improved comparison the cutting body 10 gem.
  • FIG. 7b circa FIG. 2 and FIG. 7c shows that FIG. 7b Detail marked with VIIc enlarged. It can be clearly seen that according to the invention an improved transition between the road surface 32 and the longitudinal wall 31.1 can be designed. This advantage is based on the FIGS. 8 to 11 further clarified.
  • FIG. 8 is the gem.
  • FIG. 6b resulting contour of the lane marking 31 drawn as a curve in a coordinate system.
  • FIG. 10 shows analogously the curve of the pavement marking acc. FIG. 7b .
