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, to prepare the road surface of an area to be asphalted or to compact the asphalt applied to this substrate.

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 For example, a soil compactor is known which comprises a compressor roller frame providing a frontcar substantially with a compressor roller rotatably supported about a roller rotation axis. The compressor roller frame comprises two with respect to a compressor longitudinal direction on both sides of the compressor roller arranged and carrying this longitudinal member. Between these two side members extend with respect to a compressor transverse direction on both sides of the compressor roller, ie in the direction of extension substantially in the compressor transverse direction, two cross member. About one of these two cross member of the compressor roller frame is connected to a compressor main frame, so for example, a rear-mounted carrying a drive unit. The other of the two crossbeams, that is to say the crossbeam essentially providing a front end region of the compressor, is offset upwards in a compressor height direction with respect to the crossbeam connected to the main compressor frame, thus basically has a slightly greater distance from the substrate to be compacted. This also allows the compression in slope areas, without the risk that this cross member comes into contact with the underground to be compacted.

Ein Bodenverdichter gemäß dem Oberbegriff des Anspruchs 1 ist aus der US-A-2911893 bekannt. Dieser als Anhängevorrichtung ausgebildete Bodenverdichter ist mit einem Verdichterwalzenrahmen ausgebildet, der zwischen zwei eine Verdichterwalze drehbar tragenden Längsträgern beidseits der Verdichterwalze jeweils zwei zwischen sich eine Aussparung bildende Querträger aufweist.A soil compactor according to the preamble of claim 1 is known from US-A-2911893 known. This designed as a hitch ground compactor is formed with a compressor roller frame, which has two between a compressor roller rotatably supporting longitudinal beams on both sides of the compressor roller each between two a recess forming cross member.

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 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 compressor roller rotatably supported on a compressor roller frame about a roller rotation axis, the compressor roller frame having two longitudinal members arranged with respect to a compressor longitudinal direction on both sides of the compressor roller and two with respect to a compressor transverse direction on both sides of the compressor roller and interconnecting the longitudinal members Cross member comprises, wherein the compressor roller frame is connected via one of the two cross members with a compressor main frame, wherein in the other of the two cross member at least one see-through recess is provided.

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 ground compactor according to the invention in the generally also an end portion of the soil compactor providing cross member at least one see-through recess is provided, the operator operating the compressor can see through the see-through recess on the area which is immediately before the compressor roller carried on the compressor roller frame. This allows higher precision when performing compaction work.

Um die Sicht für die Bedienperson möglichst wenig zu beeinträchtigen, ist die wenigstens eine Durchsichtaussparung in einer Verdichterhöhenrichtung nach oben im Wesentlichen offen.In order to affect the view for the operator as little as possible, the at least one see-through recess in a compressor height direction upwards is substantially open.

Um dabei gleichwohl im Bereich dieses Querträgers eine ausreichende Stabilität bereitstellen zu können, ist in einem oberen Bereich der wenigstens einen Durchsichtaussparung wenigstens eine diese in der Verdichterquerrichtung überbrückende Strebe vorgesehen, wobei die wenigstens eine Strebe eine geringere Querschnittsfläche aufweist als der andere Querträger im Bereich der wenigstens einen Durchsichtaussparung.In order nevertheless to be able to provide sufficient stability in the area of this cross member, at least one strut bridging this in the compressor transverse direction is provided in an upper region of the at least one transparent recess, wherein the at least one strut has a smaller one Cross-sectional area than the other cross member in the region of 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 cab for a compressor operating the compactor in the compressor transverse direction is arranged generally in the center of the compressor and the operator in the implementation of compression operations will generally also in the middle of the compressor - as viewed in the compressor transverse direction - will be, it is further proposed that a Viewing recess in the compressor transverse direction is centered with respect to a center of the compressor. The operator then has through this centered see-through recess extending in the compressor transverse direction field of view. Another essential contribution to the improved view of the region lying in front of the soil compactor can be achieved in that in the compressor transverse 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 transverse direction, and / or in 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 the stability can further be provided that the see-through recess is divided by a in the compressor transverse direction substantially in the middle of the compressor arranged and supported relative to the other cross member and the strut, preferably plate-like support member into two see-through recessed areas.

Bei einer alternativen, insbesondere hinsichtlich der hohen Stabilität besonders vorteilhaften erfindungsgemäßen Ausgestaltungsform umfasst der andere Querträger wenigstens zwei in einer Verdichterhöhenrichtung übereinander angeordnete und zwischen sich eine Durchsichtaussparung bildende Querträgerelemente.In an alternative, particularly in terms of high stability particularly advantageous embodiment of the present invention, the other cross member comprises at least two in a compressor height direction one above the other and between them a see-through recess forming cross member elements.

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 with an inventively constructed soil compactor in slope areas, without touching the compacting to the compacting the soil, it is proposed that the other cross member is offset in a compressor height direction with respect to a cross member upwards.

Zur Erhöhung der Einsatzvariabilität eines Bodenverdichters wird vorgeschlagen, dass an dem Verdichterwalzenrahmen ein Räumschild in einer Verdichterhöhenrichtung bewegbar getragen ist.To increase the versatility of use of a soil compactor, it is proposed that a dozer blade is movably supported in the compressor height direction on the compressor roller frame.

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 a significant impairment of the field of view for the operator by such a dozer blade, it is proposed that the dozer blade has at least one clearing blade see-through recess in an upper region in the compressor height direction. For this purpose, it can be provided, for example, that in the upper area of the ploughshare a plurality of mutually substantially parallel Räumschildstangen, preferably substantially parallel to the compressor roller axis of rotation extending, is provided, between at least two Räumschildstangen at least one plow blade-see-through recess is formed.

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 move the plow blade in the height direction, it is proposed that a plow blade lifting member, preferably piston / cylinder unit, is supported relative to the plow blade and the other cross member. In this case, preferably, the plow blade-lifting member on the support element, which is supported with respect to the other cross member and the at least one see-through recess bridging strut worn.

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 shows a generally as a front end 10 to be designated part of an in Fig. 4 shown self-propelled soil compactor 11, which is formed in the example shown as a compactor. The front carriage 10 comprises a compressor roller frame 12 with two in a longitudinal direction L compressor extending substantially plate-like longitudinal members 14, 16. Between these two side rails 14, 16 a generally designated 18 compressor roller is supported such that its roller rotation axis substantially in one Compressor transverse direction Q, that extends substantially orthogonal to the compressor longitudinal direction L, so that the two side members 14, 16 are arranged with respect to the compressor longitudinal direction L on both sides of the compressor roller 18. The compactor roller 18 may be rotatably supported on the side rails 14, 16 for rotation about its roller rotation axis.

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 members 14, 16 extend substantially in the compressor transverse direction Q, ie substantially parallel to the roller axis of rotation of the compressor roller 18, two with respect to the compressor transverse direction Q thus both sides of the compressor roller 18 arranged cross member 20, 22. The two cross members 20, 22 can basically be box-shaped and are, as well as the side members 14, 16, 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.About the cross member 20 of the compressor roller frame 12 and the front end 10 is connected to a compressor main frame 23, which may be provided for example on a rear carriage 25. To steer a ground compactor 11 thus constructed, the front carriage 10 can be connected to the main frame 23 of the compressor in such a way that it can swivel, ie be articulated, about an axis of rotation approximately extending in a direction of the compressor height 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 in that the two cross members 20, 22 are offset relative to one another in the compressor height direction H, so that the cross member 20 connected or to be connected to the main frame 23 of the compressor is offset in the compressor height direction H with respect to the other cross member 22. This has the consequence that the compressor main frame 23 and the Rear trolley 25 of the soil compactor 11 further away and essentially, for example, the front end of the soil compactor 11 providing cross member 22 is higher, in particular with its lower edge region 24 and disposed under this cross member 22 scraper 26 of the substrate to be compressed U in the compressor height direction H. upwards further away. This has the advantage that can be compressed with this front end 10 also in Anböschungsbereichen without the cross member 22 and the scraper disposed below 26 comes into contact with the underground to be compacted U.

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 for a generally positioned in the cab 27 on the rear carriage 25 operator P the view of the area to be compacted immediately adjacent, ie, for example, release before the compactor roller 18, the cross member 22, which upon movement of the front carriage 10 in the illustration of Fig. 1 Defined to the left of the front end portion of the soil compactor 11, a see-through recess 28. This in the compressor longitudinal direction L completely through the cross member 22 extending therethrough see-through recess 28 is substantially open in the compressor height direction H upwards and is limited for example by two side walls 30, 32 formed on the cross member 22 and 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 thereon on both sides and connected to the side members 14, 16. The see-through recess 28 is provided in the compressor transverse direction Q substantially centrally in the cross member 22, wherein this central region can be characterized, for example, by a plate-like support element 36 extending upward from the cross member 22 or the bottom wall 34. A strut 38 bridging the see-through recess 28 in its upper region and thus extending essentially in the compressor transverse direction Q passes through the plate-like support element 36 and is connected to the cross member 22 in the area of the side walls 30, 32. Here, for example, a welded joint with both the cross member 22, as well as with the plate-like support member 36 provide 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 for the operator P to ensure a good view of the area lying in front of the compressor roller 18 area of the substrate U, provided in the compressor transverse direction Q approximately centrally in the cross member 22 see-through recess 28 in the compressor transverse direction Q has an extension length which at least 50%, preferably at least 70% of the extension length of the cross member 22 in this direction. This ensures that the lateral edge areas in front of the compactor roller 18 are just as visible to the operator P as the central area of the substrate U to be compacted. For this purpose, it may further be provided that in the compressor height direction H the transparent recess 28 has an extension length, ie in general a depth corresponding to at least 50%, preferably at least 70%, of the extension length, 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 does not affect the view through the see-through opening 28 substantially. For stiffening also contributes to the plate-like support member 36, which is also connected to the strut 38 in the longitudinal center region due to its central positioning and due to the central positioning of the see-through recess 28. By the plate-like support member 36 thus the generally open at the top see-through recess 28 is divided into two see-through recessed 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 dozer blade 44 has at its two in the transverse direction of the compressor H spaced end portions pivot arms 46, 48, which in the region of the two side members 14, 16 with the compressor roller frame 12 are pivotally supported about a pivot axis substantially parallel to the roller rotation axis or compressor transverse direction Q. A piston / cylinder unit 50 provides a plow blade lift 52 through which the plow blade 44 can be raised or lowered. The piston / cylinder unit 50 can be connected in one of its end regions in a longitudinal center region of the rake blade 44 and can in their other end region with the cross member 22, in particular the plate-like support member 36 carried thereon, be hingedly connected.

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 affect the view of the region of the substrate U lying in front of the compressor roller 18 by the plow blade 44, the plow blade 44 is formed in its upper area in the compressor height direction H with a plurality of plow blade clearances 54. These can be essentially provided by spaces between in the compressor transverse direction Q over a shield portion 56 of the dozer blade 44 extending Räumschildstangen 58. The Räumschildstangen 58 thus extend effective for clearing the effective area of the rake blade 44 on the shield area 56 upwards, but allow the View through this area on the area of the substrate U immediately before the compacting roller 18 and before the clearing blade 44. In this case, preferably the Räumschildstangen 58 at several in the compressor transverse direction Q adjacent and also the shield area 56 bearing Räumschildplatten 60 be firmly worn.

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 region of the cross member 22 and preferably with such extension length 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 is replaced by the upper portion the compressor roller 18 is substantially free view of the substrate to be compacted U in the area in front of the compressor roller 18. The used for stabilizing or stiffening of the cross member 22 organs, in particular the strut 38, affect the view of this area of the substrate U substantially not , Likewise, the inventive design of the plow blade 44 allows a substantially undisturbed view of the area immediately in front of the plow 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 noted that this structure according to the invention in particular of the cross member 22 is then of substantial advantage when this cross member 22 in the compressor height direction H with respect to the main frame with the compressor 23 to connecting cross member 20 is offset upwards and is without providing the see-through recess in the field of view of the operator P.

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, ie the provision of a see-through recess, can also be realized in other ways. Thus, the cross member 22 may also be provided by two or more in the compressor height direction H superimposed transverse support members of the cross member, which extend between the two side rails 14, 16 and provide respective see-through recesses. Also, in embodiment of the cross member 22 in the in Fig. 1 shown several of the see-through recesses in the compressor transverse direction Q may be provided sequentially.
