This means that the side shield 10 is not actively held in its height, but always occupies a vertical position at least partially in contact with the ground.
  • the side plate 10 is limited in this case by the side plate bearing 15, in particular in its position in the working direction a and in the axial direction of the milling rotor, but not in the vertical direction.
  • an essential feature of the present side shield assembly 100 is particularly evident in those situations where the lowered side shield 10 does not stand up on a level surface with its skid 23, but in which it passes over an obstacle with its front or rear tip region.
  • the side plate pivots about the pivot axis 21.
  • two maximum adjustment positions can be defined in relation to the height-adjustable via the sealing plate 18 pivot axis 21 of the side plate 10, which in the FIGS. 3 and 4 are juxtaposed.
  • Fig. 3 is the pivot bearing 16 of the side plate 10 and the pivot axis 21 in the so-called low position.
  • the low position may be the positioning of the pivot bearing 16 that is maximally down in the vertical direction or displaced toward the bottom.
  • the low position may basically be determined, for example, by a travel limit of the cylinder-piston unit 24.
  • the low position of the pivot bearing 16 ie, the maximum downward adjustment in the vertical direction relative to the Fräswalzenkasten 8
  • the pivoting guide 17 has for this purpose a 39schildumgriff 25, which surrounds the edge region of the side plate 10 partially and in this way prevents displacement of the side plate 10 along the axial direction of the pivot axis 21.
  • the Sschildumgriff 25 is formed in such a way that it is firmly connected to the Fräswalzenkasten 8 and, in particular from the FIGS. 2b and 6 can be seen, with a Umgriffschenkel 25a, the surface of the side plate 10 overlaps.
  • the side shield handle 25 further comprises in the concrete embodiment a connecting element 25b (FIG. Fig. 6 ), which connects the Umgriffschenkel 25 a with the wall element of the Fräswalzenkastens 8.
  • the thickness of the connecting element 25b in the axial direction of the pivot axis 21 is approximately one and a half times greater than the thickness of the side plate 10 in this area.
  • the Umgriffschenkel 25a On its upper side, the Umgriffschenkel 25a has a sliding bevel 26, wherein the sliding bevel next to a hereinafter further explained guide function has a stop function for a stop pin 32 on the side plate 10.
  • the stopper bolt 32 is fixedly connected to the side plate 10 and projecting from the outer surface in the axial direction outwards and thus overlaps coming from above the sliding bevel 26.
  • the Gteitschräge 26 When lowering the side plate 10, the Gteitschräge 26 thus represents a travel limit in the lowering direction of the side plate 10 and the Stop bolt abuts against the sliding bevel 26. Once the stop pin 25 abuts against the sliding bevel 26, the pivot bearing 16 is thus in its low position. To emphasize is for This case that the contour or the spatial course of the sliding bevel 26 is not arbitrary, but has a defined course.
  • the sliding bevel 26 extends concretely in the pivoting direction with its sliding surface concentric with the pivot axis 21 of the pivot bearing 16 located in the low position Fig. 3 indicated by the indicated circular path KB1 whose center is formed by the pivot axis 21.
  • the pivot bearing 16 of the side plate 10 is also adjustable in a high position.
  • the high position is the adjustment position of the pivot bearing 16 in the vertical direction again, in which it has its maximum shifted upward adjustment position.
  • the high position is almost in Fig. 4 achieved and is determined for example by the length of the slot guide 19 in the vertical direction or the corresponding formation of the engaging in the slot guide 19 part of the sealing plate 18.
  • other stop elements may be provided, for example as part of the 9.schildumgriffs 25, which limit the lifting adjustment of the pivot bearing in the vertical direction upwards.
  • the stopper pin 25 is no longer on the sliding bevel 26 of the Soschildumgriffs 25 at.
  • the pivot bearing 16 is an at least almost concentric with the pivot axis extending guide means for the side plate available.
  • This is part of a slot guide 27, comprising in particular a guide arm 28, a curved slot 29 in this guide arm 28 and guided in a slot 29 bolt 31 (FIGS. Fig. 2b ).
  • the guide arm 28 is part of the side plate 10 and arranged in the direction of travel to the pivot axis 21 spaced from the pivot axis 21 on the pivot bearing 16 opposite part of the side plate 10.
  • the slot 29 Through the slot 29 is also a guide pin (not visible in the figures), which is connected via a further soschildumgriff 30 fixed to the Fräswalzenkasten 8. From the guide pin 31 is in the FIGS. 3 and 4 for further clarification, the position of the longitudinal axis of the guide pin 31, which runs parallel to the pivot axis 21, indicated at 31. Also the training of the curved Long hole 29 fulfills certain conditions and is not arbitrary, in particular with regard to the size and the course of the slot 29. The essential requirement is that the oblong hole 29 includes a family of curves of pivoting curves which lie on a circular path KB2 in the low position (FIG. Fig. 3 ) and in the high position ( Fig. 4 ) are concentric with the pivot axis 21.
  • the distance of the circular path KB2 to the pivot axis 21 is thereby defined concretely by the longitudinal axis 31 of the guide pin projecting through the curved slot 29.
  • the slot 29 may be formed in particular in such a way that a part of its edge contours also at least in the low and / or in the high position of the pivot bearing 16 is also concentric with the pivot axis 21.
  • the slot 29 thus fulfills the feature "concentric with the pivot axis 21 of the pivot bearing 16 extending guide curve 26".
  • the present arrangement ensures that the side plate 10 can be guided both in the high position and in the low position on the circular path KB2 within the slot 29. Also, the curved slot 29 together with the guide arm 28 and the guide pin thus a concentric to the pivot axis 21 extending guide means for the side plate 10.
  • FIGS. 3 and 4 illustrate further the beneficial effects of the formation of a side shield assembly according to the invention, namely specifically when driving over a rising in the vertical direction of the soil surface obstacle 33.
  • This may for example be the case when the milling device 1 is retracted from an outside into an existing Fräsbett or, is moved out of a milling bed or even when passing on lying on the front side of the milling rotor surveys and / or obstacles is passed.
  • Such obstacles are generally characterized by the fact that they protrude in vertical direction from the ground 34 and thus represent an object to be overcome with the height H from the side plate 10.
  • FIGS. 3 and 4 is an example of such an obstacle fragmentary a manhole cover element 33 indicated at the almost flush and with a constant depth of cut, ie without height adjustment of the milling rotor 13, to be milled past.
  • the side plate 10 Starting from the normal position of the side plate 10, in the side plate 10, for example according to Fig. 2 , stands upright with his skid 23 on the ground and the pivot bearing 16 is in the low position, the side plate 10 abuts with its tip first against the obstacle 33 at a continuation of the milling work in the direction a.
  • the bent-up tip portion of the skid 23 of the side shield is through the obstacle 32 with its tip portion pressed upward and the side plate pivots about the pivot axis 21 at an angle ⁇ in the direction of arrow b ( Fig. 3 ) up.
  • the pivot bearing 16 initially remains in the lower position.
  • the abutting on the sliding bevel 26 stop pin 32 slides over this curved slip slope against the working direction a on the curved path KB1, which runs concentrically to the pivot axis 21 in the pivoting plane.
  • the axis 31 slides in the side shield handle 30, which partially surrounds the guide arm 28, along the curved slot 29 on the cam track KB2, which also runs concentrically to the pivot axis 21 in the pivot plane.
  • the rear part of the side plate 10, in which the pivot bearing 16 of the side plate bearing 15 is arranged lifts in the vertical direction above.
  • the sealing plate 18 moves in the slot guide 19 upwards and takes the pivot bearing 16 together with the side plate 10 to the high position of the pivot bearing 10 with.
  • a pivoting movement of the side plate around the pivot axis 21 runs opposite to the arrow b until the side plate 10 again its almost horizontal position (comparable to Fig. 2 , offset only in vertical direction).
  • the stopper bolt 32 thus no longer rests with its stopper bolt 32 on the sliding bevel 26 when the pivot bearing 16 is in a high position, guiding of the side shield 10 continues via the slot guide 27.
  • the side plate 10 tilts at an angle ⁇ with its tip region lying forward in the working direction a about the pivot axis 21 downwards in the direction of arrow c Fig. 4 towards the bottom 34, as it is in Fig. 4 is reproduced.
  • This pivoting movement is also performed by the slot guide 27, whose longitudinal extent runs along the circular path KB2.
  • the sealing plate 18 slips down in the slot guide until the side plate 10 rests with the long side of his skid 23 on the floor 34 or the pivot bearing is in the low position, in which the stop pin 32 against the sliding bevel 26 abuts and prevents further adjustment of the pivot bearing or the sealing plate 18 down.
  • FIGS. 5 and 6 serve to illustrate further constructive details of the side plate bearing 15.
  • Fig. 5 is a section as a review of the sealing plate 18th represented by the side plate 10.
  • Fig. 6 is a sectional view taken along the line AA Fig. 5 and illustrates in particular the relative arrangement of side plate 10, sealing plate 18 and milling drum box 8. Both figures relate to the low position of the pivot bearing 16, as for example Fig. 2 evident. Particularly clear is in particular from Fig. 6 how the Soschildumgriff 25 is formed in the form of a fork-shaped element which surrounds the rearwardly oriented edge region of the side plate 10 partially and thereby achieved, for example, a position stabilization in the axial direction of the pivot axis 21.
