Description

Die vorliegende Erfindung betrifft einen Bodenverdichter, der beispielsweise eingesetzt werden kann, um im Straßenbau den Untergrund eines zu asphaltierenden Bereichs vorzubereiten oder den auf diesen Untergrund ausgebrachten Asphalt zu verdichten.The present invention relates to a soil compactor which can be used, for example, in road construction to prepare the subsoil of an area to be asphalted or to compact the asphalt that has been spread on this subsoil.

Aus der DE 10 2013 203 860 A1 ist ein Bodenverdichter bekannt, welcher einen im Wesentlichen einen Vorderwagen bereitstellenden Verdichterwalzenrahmen mit einer daran um eine Walzendrehachse drehbar getragenen Verdichterwalze umfasst. Der Verdichterwalzenrahmen umfasst zwei bezüglich einer Verdichterlängsrichtung beidseits der Verdichterwalze angeordnete und diese tragende Längsträger. Zwischen diesen beiden Längsträgern erstrecken sich bezüglich einer Verdichterquerrichtung beidseits der Verdichterwalze, also mit Erstreckungsrichtung im Wesentlichen in Verdichterquerrichtung, zwei Querträger. Über einen dieser beiden Querträger ist der Verdichterwalzenrahmen an einem Verdichterhauptrahmen, also beispielsweise einen auch ein Antriebsaggregat tragenden Hinterwagen angebunden. Der andere der beiden Querträger, also der im Wesentlichen einen vorderen Endbereich des Verdichters bereitstellende Querträger, ist bezüglich des mit dem Verdichterhauptrahmen verbundenen Querträgers in einer Verdichterhöhenrichtung nach oben versetzt, weist also grundsätzlich einen etwas größeren Abstand zu dem zu verdichtenden Untergrund auf. Dies ermöglicht auch das Verdichten in Böschungsbereichen, ohne der Gefahr, dass dieser Querträger in Kontakt mit dem zu verdichtenden Untergrund gelangt.From the DE 10 2013 203 860 A1 a soil compactor is known which comprises a compactor roller frame which essentially provides a front end and a compactor roller rotatably supported thereon about a roller axis of rotation. The compactor roller frame comprises two longitudinal beams which are arranged on both sides of the compactor roller with respect to a longitudinal direction of the compactor and which support the latter. Between these two longitudinal supports, two transverse supports extend with respect to a transverse direction of the compressor on both sides of the compressor roller, that is to say with the direction of extension essentially in the transverse direction of the compressor. Via one of these two cross members, the compressor roller frame is connected to a compressor main frame, that is to say, for example, to a rear carriage that also supports a drive unit. The other of the two crossbeams, i.e. the crossbeam which essentially provides a front end area of the compressor, is offset upward in a compressor height direction with respect to the crossbeam connected to the compressor main frame, so basically has a somewhat greater distance from the subsoil to be compacted. This also enables compaction in slope areas without the risk of this cross member coming into contact with the subsoil to be compacted.

Es ist die Aufgabe der vorliegenden Erfindung, einen Bodenverdichter bereitzustellen, bei welchem für eine den Bodenverdichter bedienende Bedienperson eine verbesserte Sicht auf den vor dem Bodenverdichter liegenden zu verdichtenden Bodenbereich gegeben ist.It is the object of the present invention to provide a soil compactor in which an operator operating the soil compactor has an improved view of the soil area to be compacted lying in front of the soil compactor.

Erfindungsgemäß wird diese Aufgabe gelöst durch einen Bodenverdichter, umfassend eine an einem Verdichterwalzenrahmen um eine Walzendrehachse drehbar getragene Verdichterwalze, wobei der Verdichterwalzenrahmen zwei bezüglich einer Verdichterlängsrichtung beidseits der Verdichterwalze angeordnete, diese tragende Längsträger und zwei bezüglich einer Verdichterquerrichtung beidseits der Verdichterwalze angeordnete und die Längsträger miteinander verbindende Querträger umfasst, wobei der Verdichterwalzenrahmen über einen der beiden Querträger mit einem Verdichterhauptrahmen verbunden ist, wobei in dem anderen der beiden Querträger wenigstens eine Durchsichtaussparung vorgesehen ist.According to the invention, this object is achieved by a soil compactor, comprising a compactor drum rotatably supported on a compactor drum frame about a drum axis of rotation, the compactor drum frame having two longitudinal beams on both sides of the compactor drum with respect to a compactor longitudinal direction and two longitudinal beams that connect and connect the longitudinal beams with respect to a compactor transverse direction on both sides of the compactor drum Comprises cross member, the compressor roller frame being connected to a compressor main frame via one of the two cross members, with at least one see-through recess being provided in the other of the two cross members.

Da bei dem erfindungsgemäßen Bodenverdichter in dem im Allgemeinen auch einen Endbereich des Bodenverdichters bereitstellenden Querträger wenigstens eine Durchsichtaussparung vorgesehen ist, kann die den Verdichter bedienende Bedienperson durch die Durchsichtaussparung hindurch auf den Bereich sehen, welcher unmittelbar vor der an dem Verdichterwalzenrahmen getragenen Verdichterwalze liegt. Dies ermöglicht eine höhere Präzision bei Durchführung von Verdichtungsarbeiten.Since in the soil compactor according to the invention at least one see-through cutout is provided in the cross member which generally also provides an end area of the soil compactor, the operator operating the compactor can see through the see-through cutout at the area which is located immediately in front of the compactor roller carried on the compactor roller frame. This enables greater precision when performing compaction work.

Um die Sicht für die Bedienperson möglichst wenig zu beeinträchtigen, wird vorgeschlagen, dass die wenigstens eine Durchsichtaussparung in einer Verdichterhöhenrichtung nach oben im Wesentlichen offen ist.In order to impair the operator's view as little as possible, it is proposed that the at least one see-through cutout be essentially open upward in a compressor height direction.

Um dabei gleichwohl im Bereich dieses Querträgers eine ausreichende Stabilität bereitstellen zu können, wird weiter vorgeschlagen, dass in einem oberen Bereich der wenigstens einen Durchsichtaussparung wenigstens eine diese in der Verdichterquerrichtung überbrückende Strebe vorgesehen ist, wobei die wenigstens eine Strebe eine geringere Querschnittsfläche aufweist als der andere Querträger im Bereich der wenigstens einen Durchsichtaussparung.In order to be able to provide sufficient stability in the area of this cross member, it is further proposed that at least one strut bridging this in the compressor transverse direction is provided in an upper area of the at least one see-through recess, the at least one strut having a smaller cross-sectional area than the other Cross member in the area of the at least one see-through recess.

Da ein Führerstand für eine den Bodenverdichter bedienende Bedienperson in der Verdichterquerrichtung im Allgemeinen mittig im Verdichter angeordnet ist und die Bedienperson bei der Durchführung von Verdichtungsvorgängen sich im Allgemeinen auch im Mittenbereich des Verdichters - betrachtet in der Verdichterquerrichtung - aufhalten wird, wird weiter vorgeschlagen, dass eine Durchsichtaussparung in der Verdichterquerrichtung bezüglich einer Mitte des Verdichters zentriert angeordnet ist. Die Bedienperson hat dann durch diese zentrierte Durchsichtaussparung hindurch ein sich in der Verdichterquerrichtung erweiterndes Sichtfeld. Ein weiterer wesentlicher Beitrag zur verbesserten Sicht auf den vor dem Bodenverdichter liegenden Bereich kann dadurch erreicht werden, dass in der Verdichterquerrichtung die wenigstens eine Durchsichtaussparung sich über wenigstens 50%, vorzugsweise wenigstens 70% der Erstreckungslänge des anderen Querträgers in der Verdichterquerrichtung erstreckt, oder/und dass in einer Verdichterhöhenrichtung die wenigstens eine Durchsichtaussparung sich über wenigstens 50%, vorzugsweise wenigstens 70%, der Erstreckungslänge des anderen Querträgers in der Verdichterhöhenrichtung erstreckt.Since a driver's cab for an operator operating the soil compactor is generally arranged centrally in the compactor in the transverse direction of the compactor, and the operator is generally located when performing compacting processes Also in the middle area of the compressor - viewed in the compressor transverse direction - it is further proposed that a see-through cutout be arranged centered in the compressor transverse direction with respect to a center of the compressor. The operator then has a field of vision widening in the transverse direction of the compressor through this centered see-through recess. Another essential contribution to the improved view of the area in front of the soil compactor can be achieved in that the at least one see-through recess extends in the transverse direction of the compactor over at least 50%, preferably at least 70% of the extension length of the other cross member in the transverse direction of the compactor, and / or that in a compressor height direction the at least one see-through recess extends over at least 50%, preferably at least 70%, of the extension length of the other cross member in the compressor height direction.

Zur Stabilitätserhöhung kann weiter vorgesehen sein, dass die Durchsichtaussparung durch ein in der Verdichterquerrichtung im Wesentlichen in der Mitte des Verdichters angeordnetes und bezüglich des anderen Querträgers und der Strebe abgestütztes, vorzugsweise plattenartiges Trägerelement in zwei Durchsichtaussparungsbereiche unterteilt ist.To increase stability, provision can also be made for the see-through recess to be divided into two see-through recess areas by a preferably plate-like carrier element arranged in the compressor transverse direction essentially in the middle of the compressor and supported with respect to the other cross member and the strut.

Bei einer alternativen, insbesondere hinsichtlich der hohen Stabilität besonders vorteilhaften Ausgestaltungsform wird vorgeschlagen, dass der andere Querträger wenigstens zwei in einer Verdichterhöhenrichtung übereinander angeordnete und zwischen sich eine Durchsichtaussparung bildende Querträgerelemente umfasst.In an alternative embodiment, which is particularly advantageous with regard to the high stability, it is proposed that the other cross member comprises at least two cross member elements arranged one above the other in a compressor height direction and forming a see-through recess between them.

Um mit einem erfindungsgemäß aufgebauten Bodenverdichter auch in Böschungsbereichen verdichten zu können, ohne mit dem Verdichterwalzenrahmen den zu verdichtenden Boden zu berühren, wird vorgeschlagen, dass der andere Querträger in einer Verdichterhöhenrichtung bezüglich des einen Querträgers nach oben versetzt ist.In order to be able to compact embankment areas with a soil compactor constructed according to the invention without touching the soil to be compacted with the compactor roller frame, it is proposed that the other cross member be offset upward in a compactor vertical direction with respect to one cross member.

Zur Erhöhung der Einsatzvariabilität eines Bodenverdichters wird vorgeschlagen, dass an dem Verdichterwalzenrahmen ein Räumschild in einer Verdichterhöhenrichtung bewegbar getragen ist.In order to increase the variability in use of a soil compactor, it is proposed that a clearing blade be carried on the compactor roller frame such that it can be moved in a compactor height direction.

Um durch einen derartigen Räumschild keine wesentliche Beeinträchtigung des Sichtfeldes für die Bedienperson zu erzeugen, wird vorgeschlagen, dass der Räumschild in einem in der Verdichterhöhenrichtung oberen Bereich wenigstens eine Räumschild-Durchsichtaussparung aufweist. Hierzu kann beispielsweise vorgesehen sein, dass im oberen Bereich des Räumschilds eine Mehrzahl von zueinander im Wesentlichen parallel verlaufenden Räumschildstangen, vorzugsweise im Wesentlichen parallel zur Verdichterwalzendrehachse sich erstreckend, vorgesehen ist, wobei zwischen wenigstens zwei Räumschildstangen wenigstens eine Räumschild-Durchsichtaussparung gebildet ist.In order not to produce any significant impairment of the field of vision for the operator by means of such a clearing blade, it is proposed that the clearing blade have at least one clearing blade see-through recess in an upper area in the direction of the compressor height. For this purpose it can be provided, for example, that in the upper area of the dozer blade a plurality of dozer blade rods extending essentially parallel to one another, preferably extending essentially parallel to the compressor roller axis of rotation, is provided, with at least one clearing blade see-through recess being formed between at least two dozer rods.

Um den Räumschild in der Höhenrichtung bewegen zu können, wird vorgeschlagen, dass ein Räumschild-Huborgan, vorzugsweise Kolben/Zylinder-Einheit, bezüglich des Räumschilds und des anderen Querträgers abgestützt ist. Dabei ist vorzugsweise das Räumschild-Huborgan an dem Trägerelement, welches bezüglich des anderen Querträgers und der die wenigstens eine Durchsichtaussparung überbrückenden Strebe abgestützt ist, getragen.In order to be able to move the dozer blade in the vertical direction, it is proposed that a dozer blade lifting member, preferably a piston / cylinder unit, be supported with respect to the dozer blade and the other cross member. In this case, the clearing blade lifting element is preferably carried on the carrier element which is supported with respect to the other crossbeam and the strut bridging the at least one see-through recess.

Die Fig. 1 zeigt einen allgemein als Vorderwagen 10 zu bezeichnenden Teil eines in Fig. 4 dargestellten selbstfahrenden Bodenverdichters 11, der im dargestellten Beispiel als Walzenzug ausgebildet ist. Der Vorderwagen 10 umfasst einen Verdichterwalzenrahmen 12 mit zwei in einer Verdichterlängsrichtung L sich erstreckenden, im Wesentlichen plattenartig ausgebildeten Längsträgern 14, 16. Zwischen diesen beiden Längsträgern 14, 16 ist eine allgemein mit 18 bezeichnete Verdichterwalze derart getragen, dass deren Walzendrehachse sich im Wesentlichen in einer Verdichterquerrichtung Q, also im Wesentlichen orthogonal zur Verdichterlängsrichtung L erstreckt, so dass die beiden Längsträger 14, 16 bezüglich der Verdichterlängsrichtung L beidseits der Verdichterwalze 18 angeordnet sind. Die Verdichterwalze 18 kann an den Längsträgern 14, 16 zur Rotation um ihre Walzendrehachse drehbar getragen sein.The Fig. 1 FIG. 11 shows a part of an in FIG Fig. 4 illustrated self-propelled soil compactor 11, which is designed as a roller compactor in the example shown. The front end 10 comprises a compressor roller frame 12 with two essentially plate-like longitudinal supports 14, 16 extending in a longitudinal direction L of the compressor. Between these two longitudinal supports 14, 16 a compressor roller, generally designated 18, is supported in such a way that its roller axis of rotation is essentially in a Compressor transverse direction Q, that is to say extends essentially orthogonally to the compressor longitudinal direction L, so that the two longitudinal members 14, 16 are arranged on both sides of the compressor roller 18 with respect to the compressor longitudinal direction L. The compactor roller 18 can be rotatably supported on the longitudinal beams 14, 16 for rotation about its roller axis of rotation.

Zwischen den beiden Längsträgern 14, 16 erstrecken sich im Wesentlichen in der Verdichterquerrichtung Q, also im Wesentlichen auch parallel zur Walzendrehachse der Verdichterwalze 18, zwei bezüglich der Verdichterquerrichtung Q somit beidseits der Verdichterwalze 18 angeordnete Querträger 20, 22. Die beiden Querträger 20, 22 können grundsätzlich kastenartig ausgebildet sein und sind, ebenso wie die Längsträger 14, 16, als Stahlteile ausgeführt.Between the two longitudinal beams 14, 16 extend essentially in the transverse direction Q of the compressor, i.e. also essentially parallel to the roller axis of rotation of the compressor roller 18, two transverse supports 20, 22 with respect to the transverse direction Q of the compressor, thus arranged on both sides of the compressor roller 18. The two transverse supports 20, 22 can basically be designed like a box and, like the longitudinal members 14, 16, are designed as steel parts.

Über den Querträger 20 ist der Verdichterwalzenrahmen 12 bzw. der Vorderwagen 10 mit einem Verdichterhauptrahmen 23, der beispielsweise an einem Hinterwagen 25 vorgesehen sein kann, verbunden. Zum Lenken eines so aufgebauten Bodenverdichters 11 kann der Vorderwagen 10 mit dem Verdichterhauptrahmen 23 beispielsweise um eine näherungsweise in einer Verdichterhöhenrichtung H sich erstreckende Schwenkachse schwenkbar, also gelenkig verbunden sein.Via the cross member 20, the compressor roller frame 12 or the front carriage 10 is connected to a compressor main frame 23, which can be provided on a rear carriage 25, for example. To steer a soil compactor 11 constructed in this way, the front end 10 can be pivoted, that is to say articulated, with the compactor main frame 23, for example, about a swivel axis extending approximately in a compactor vertical direction H.

Man erkennt in Fig. 1, dass die beiden Querträger 20, 22 in der Verdichterhöhenrichtung H zueinander versetzt liegen, so dass der mit dem Verdichterhauptrahmen 23 verbundene oder zu verbindende Querträger 20 in der Verdichterhöhenrichtung H bezüglich des anderen Querträgers 22 nach unten versetzt liegt. Dies hat zur Folge, dass der vom Verdichterhauptrahmen 23 bzw. dem Hinterwagen 25 des Bodenverdichters 11 weiter entfernt liegende und im Wesentlichen beispielsweise den vorderen Endbereich des Bodenverdichters 11 bereitstellende Querträger 22 höher liegt, insbesondere mit seinem unteren Randbereich 24 bzw. einem unter diesem Querträger 22 angeordneten Abstreifer 26 von dem zu verdichtenden Untergrund U in der Verdichterhöhenrichtung H nach oben weiter entfernt liegt. Dies hat zum Vorteil, dass mit diesem Vorderwagen 10 auch in Anböschungsbereichen verdichtet werden kann, ohne dass der Querträger 22 bzw. der darunter angeordnete Abstreifer 26 in Kontakt mit dem zu verdichtenden Untergrund U kommt.One recognizes in Fig. 1 that the two cross members 20, 22 are offset from one another in the compressor height direction H, so that the cross member 20 connected or to be connected to the compressor main frame 23 is offset downwards in the compressor height direction H with respect to the other cross member 22. This has the consequence that the compressor main frame 23 or the The rear carriage 25 of the soil compactor 11 is further away and essentially provides, for example, the front end area of the soil compactor 11, is higher up, in particular with its lower edge area 24 or a scraper 26 arranged under this crossmember 22 from the subsoil U to be compacted in the compactor vertical direction H. is further away upwards. This has the advantage that this front vehicle 10 can also be used to compact in areas of the slope without the cross member 22 or the scraper 26 arranged below coming into contact with the subsoil U to be compacted.

Um für eine im Allgemeinen im Führerstand 27 am Hinterwagen 25 positionierte Bedienperson P den Blick auf den zu verdichtenden Bodenbereich unmittelbar benachbart, also beispielsweise vor der Verdichterwalze 18 freizugeben, weist der Querträger 22, welcher bei Bewegung des Vorderwagens 10 in der Darstellung der Fig. 1 nach links den vorderen Endbereich des Bodenverdichters 11 definiert, eine Durchsichtaussparung 28 auf. Diese in der Verdichterlängsrichtung L sich vollständig durch den Querträger 22 hindurch erstreckende Durchsichtaussparung 28 ist im Wesentlichen in der Verdichterhöhenrichtung H nach oben offen und ist z.B. durch zwei am Querträger 22 gebildete Seitenwandungen 30, 32 bzw. eine Bodenwandung 34 begrenzt. Im Bereich der Durchsichtaussparung 28 weist der Querträger 22 eine geringere Querschnittsabmessung auf, als in den beiden beidseits daran vorgesehenen und an die Längsträger 14 ,16 angebundenen Bereichen. Die Durchsichtaussparung 28 ist in der Verdichterquerrichtung Q im Wesentlichen mittig im Querträger 22 vorgesehen, wobei dieser Mittenbereich beispielsweise durch ein vom Querträger 22 bzw. der Bodenwandung 34 sich nach oben erstreckendes, plattenartiges Trägerelement 36 gekennzeichnet sein kann. Eine die Durchsichtaussparung 28 in deren oberem Bereich überbrückende und somit sich im Wesentlichen in der Verdichterquerrichtung Q erstreckende Strebe 38 durchsetzt das plattenartige Trägerelement 36 und ist im Bereich der Seitenwandungen 30, 32 an den Querträger 22 angebunden. Hier kann beispielsweise eine Schweißverbindung sowohl mit dem Querträger 22, als auch mit dem plattenartigen Trägerelement 36 für eine stabile Verbindung sorgen.In order to allow an operator P, who is generally positioned in the driver's cab 27 on the rear carriage 25, to see the ground area to be compacted immediately adjacent, for example in front of the compactor roller 18, the cross member 22, which, when the front carriage 10 moves in the illustration in FIG Fig. 1 the front end region of the soil compactor 11 is defined to the left, a see-through recess 28. This see-through recess 28, which extends completely through the cross member 22 in the compressor longitudinal direction L, is essentially open at the top in the compressor height direction H and is delimited, for example, by two side walls 30, 32 formed on the cross member 22 or a bottom wall 34. In the area of the see-through recess 28, the cross member 22 has a smaller cross-sectional dimension than in the two areas provided on both sides and connected to the longitudinal members 14, 16. The see-through recess 28 is provided in the transverse direction Q of the compressor essentially in the center of the cross member 22, this central area being characterized, for example, by a plate-like carrier element 36 extending upward from the cross member 22 or the bottom wall 34. A strut 38 bridging the see-through cutout 28 in its upper area and thus essentially extending in the transverse direction Q of the compressor penetrates the plate-like carrier element 36 and is connected to the cross member 22 in the area of the side walls 30, 32. Here, for example, a welded connection both with the cross member 22 and with the plate-like carrier element 36 can ensure a stable connection.

Um für die Bedienperson P eine gute Sicht auf den vor der Verdichterwalze 18liegenden Bereich des Untergrunds U zu gewährleisten, weist die in der Verdichterquerrichtung Q näherungsweise mittig im Querträger 22 vorgesehene Durchsichtaussparung 28 in der Verdichterquerrichtung Q eine Erstreckungslänge auf, die wenigstens 50 %, vorzugsweise wenigstens 70 % der Erstreckungslänge des Querträgers 22 in dieser Richtung beträgt. Dadurch wird gewährleistet, dass für die Bedienperson P die seitlichen Randbereiche vor der Verdichterwalze 18 ebenso gut einzusehen sind, wie der Mittenbereich des zu verdichtenden Untergrunds U. Hierzu kann des Weiteren vorgesehen sein, dass in der Verdichterhöhenrichtung H die Durchsichtaussparung 28 eine Erstreckungslänge, also allgemein eine Tiefe, aufweist, die wenigstens 50 %, vorzugsweise wenigstens 70 % der Erstreckungslänge, im Allgemeinen also der Dicke, des Querträgers 22 in dieser Verdichterhöhenrichtung H entspricht.In order to ensure that the operator P has a good view of the area of the subsurface U located in front of the compactor roller 18, the see-through recess 28 provided in the transverse direction Q of the compactor approximately centrally in the cross member 22 has an extension length of at least 50%, preferably at least in the transverse direction of the compactor 70% of the extension length of the cross member 22 in this direction. This ensures that the operator P can see the lateral edge areas in front of the compactor roller 18 just as easily as the central area of the subsoil U to be compacted. For this purpose, provision can also be made for the transparent recess 28 to have an extension length in the compactor vertical direction H, i.e. generally a depth, which corresponds to at least 50%, preferably at least 70% of the extension length, that is to say generally the thickness, of the cross member 22 in this compressor height direction H.

Die Strebe 38 versteift den Querträger 22, beeinträchtigt jedoch die Sicht durch die Durchsichtöffnung 28 hindurch im Wesentlichen nicht. Zur Versteifung trägt auch das plattenartige Trägerelement 36 bei, welches aufgrund seiner mittigen Positionierung und aufgrund der mittigen Positionierung der Durchsichtaussparung 28 auch mit der Strebe 38 in deren Längenmittenbereich verbunden ist. Durch das plattenartige Trägerelement 36 wird somit die grundsätzlich nach oben offene Durchsichtaussparung 28 in zwei Durchsichtaussparungsbereiche 40, 42 unterteilt.The strut 38 stiffens the cross member 22, but essentially does not impair the view through the see-through opening 28. The plate-like support element 36 also contributes to the stiffening, which due to its central positioning and due to the central positioning of the see-through cut-out 28 is also connected to the strut 38 in its longitudinal center area. The plate-like support element 36 thus divides the see-through recess 28, which is basically open at the top, into two see-through recess areas 40, 42.

Die Fig. 2 zeigt den in Fig. 1 dargestellten Vorderwagen 10 mit seinem Verdichterwalzenrahmen 12 in Verbindung mit einem daran schwenkbar getragenen Räumschild 44. Der Räumschild 44 weist an seinen beiden in der Verdichterquerrichtung H in Abstand liegenden Endbereichen Schwenkarme 46, 48 auf, welche im Bereich der beiden Längsträger 14, 16 mit dem Verdichterwalzenrahmen 12 um eine zur Walzendrehachse bzw. Verdichterquerrichtung Q im Wesentlichen parallele Schwenkachse schwenkbar getragen sind. Eine Kolben/Zylinder-Einheit 50 stellt ein Räumschild-Huborgan 52 bereit, durch welches der Räumschild 44 angehoben bzw. abgesenkt werden kann. Die Kolben/Zylinder-Einheit 50 kann dabei in einem ihrer Endbereiche in einem Längenmittenbereich an den Räumschild 44 angebunden sein und kann in ihrem anderen Endbereich mit dem Querträger 22, insbesondere dem daran getragenen plattenartigen Trägerelement 36, gelenkig verbunden sein.The Fig. 2 shows the in Fig. 1 The front end 10 shown with its compressor roller frame 12 in connection with a plow blade 44 pivotably supported thereon. The plow blade 44 has pivot arms 46, 48 at its two end areas spaced apart in the compressor transverse direction H, which in the area of the two longitudinal members 14, 16 with the compressor roller frame 12 are supported pivotably about a pivot axis that is essentially parallel to the roll axis of rotation or the transverse direction of the compressor Q. A piston / cylinder unit 50 provides a blade lifting element 52, by means of which the blade 44 can be raised or lowered. The piston / cylinder unit 50 can be connected to the clearing blade 44 in one of its end regions in a longitudinal center region and can in its The other end region can be connected in an articulated manner to the cross member 22, in particular the plate-like carrier element 36 carried thereon.

Um die Sicht auf den vor der Verdichterwalze 18 liegenden Bereich des Untergrunds U durch den Räumschild 44 nicht wesentlich zu beeinträchtigen, ist der Räumschild 44 in seinen in der Verdichterhöhenrichtung H oberen Bereich mit einer Mehrzahl von Räumschild-Durchsichtaussparungen 54 ausgebildet. Diese können im Wesentlichen bereitgestellt sein durch Zwischenräume zwischen in der Verdichterquerrichtung Q über einem Schildbereich 56 des Räumschilds 44 sich erstreckende Räumschildstangen 58. Die Räumschildstangen 58 verlängern somit den zum Räumen effektiv wirksamen Bereich des Räumschilds 44 über den Schildbereich 56 nach oben hinaus, ermöglichen jedoch die Sicht durch diesen Bereich hindurch auf den Bereich des Untergrunds U unmittelbar vor der Verdichterwalze 18 bzw. vor dem Räumschild 44. Dabei können vorzugsweise die Räumschildstangen 58 an mehreren in der Verdichterquerrichtung Q nebeneinander liegenden und auch den Schildbereich 56 tragenden Räumschildplatten 60 fest getragen sein.In order not to significantly impair the view of the area of the subsurface U lying in front of the compactor roller 18 through the clearing blade 44, the clearing blade 44 is designed with a plurality of clearing blade see-through recesses 54 in its upper area in the direction H of the compactor. These can essentially be provided by gaps between plow rods 58 extending in the compressor transverse direction Q over a shield area 56 of the plow blade 44. The plow rods 58 thus extend the area of the plow blade 44 that is effective for clearing upwards beyond the blade area 56, but enable the View through this area to the area of the subsurface U directly in front of the compactor roller 18 or in front of the clearing blade 44. In this case, the clearing blade rods 58 can preferably be firmly supported on several blade plates 60 lying next to one another in the compressor transverse direction Q and also carrying the blade area 56.

Durch das Bereitstellen der Durchsichtaussparung 28, vorzugsweise in einem mittigen Bereich des Querträgers 22 und vorzugsweise mit derartiger Erstreckungslänge, dass diese wenigstens 50%, vorzugsweise wenigstens 70% der Erstreckungslänge des Querträgers 22 in der Verdichterquerrichtung Q einnimmt, erhält die Bedienperson P über den oberen Bereich der Verdichterwalze 18 hinweg im Wesentlichen freie Sicht auf den zu verdichtenden Untergrund U im Bereich vor der Verdichterwalze 18. Die zur Stabilisierung bzw. Versteifung des Querträgers 22 eingesetzten Organe, insbesondere die Strebe 38, beeinträchtigen die Sicht auf diesen Bereich des Untergrunds U im Wesentlichen nicht. Ebenso ermöglicht die erfindungsgemäße Ausgestaltung des Räumschilds 44 eine im Wesentlichen unbeeinträchtigte Sicht auf den Bereich unmittelbar vor dem Räumschild 44.By providing the see-through recess 28, preferably in a central area of the cross member 22 and preferably with an extension length such that it occupies at least 50%, preferably at least 70% of the extension length of the cross member 22 in the compressor transverse direction Q, the operator P receives over the upper region The compactor roller 18 has an essentially free view of the subsurface U to be compacted in the area in front of the compactor roller 18. The organs used to stabilize or stiffen the cross member 22, in particular the strut 38, do not substantially impair the view of this area of the subsurface U . The design of the clearing blade 44 according to the invention also enables a substantially unobstructed view of the area immediately in front of the clearing blade 44.

Es ist darauf hinzuweisen, dass dieser erfindungsgemäße Aufbau insbesondere des Querträgers 22 dann von substantiellem Vorteil ist, wenn dieser Querträger 22 in der Verdichterhöhenrichtung H bezüglich des mit dem Verdichterhauptrahmen 23 zu verbindenden Querträgers 20 nach oben versetzt ist und ohne Bereitstellen der Durchsichtaussparung im Sichtfeld der Bedienperson P liegt.It should be pointed out that this structure according to the invention, in particular of the cross member 22, is of substantial advantage when this cross member 22 is in the compressor height direction H with respect to the compressor main frame 23 connecting cross member 20 is offset upwards and lies in the field of vision of the operator P without providing the see-through recess.

Die Prinzipien der vorliegenden Erfindung, also das Bereitstellen einer Durchsichtaussparung, können auch in anderer Weise realisiert werden. So kann der Querträger 22 auch durch zwei oder mehrere in der Verdichterhöhenrichtung H übereinander angeordnete Querträgerelemente des Querträgers bereitgestellt sein, die sich zwischen den beiden Längsträgern 14, 16 erstrecken und zwischen sich jeweilige Durchsichtaussparungen bereitstellen. Auch können bei Ausgestaltung des Querträgers 22 in der in Fig. 1 dargestellten Art und Weise mehrere der Durchsichtaussparungen in der Verdichterquerrichtung Q aufeinanderfolgend vorgesehen sein.The principles of the present invention, that is to say the provision of a see-through cutout, can also be implemented in other ways. Thus, the cross member 22 can also be provided by two or more cross member elements of the cross member arranged one above the other in the compressor vertical direction H, which extend between the two longitudinal members 14, 16 and provide respective see-through cutouts between them. Also, when the cross member 22 is configured in the in Fig. 1 In the manner shown, several of the see-through cutouts may be provided in succession in the transverse direction Q of the compressor.
