Um bei der Verdichtung von Untergrund, wie zum Beispiel Asphalt, Erdreich oder Kies, ein besseres Verdichtungsergebnis erzielen zu können, ist es bekannt, der statischen Belastung des zu verdichtenden Untergrundes durch das Gewicht einer auf diesem abrollenden Verdichterwalze bzw. des über diese auf dem Untergrund abgestützten Verdichters dynamische Zustände der Verdichterwalze zu überlagern. So kann eine Verdichterwalze zum Erzeugen eines sogenannten Vibrationszustandes im Wesentlichen vertikal, also in einer Richtung im Wesentlichen orthogonal zur Oberfläche des zu verdichtenden Untergrunds, periodisch auf und ab beschleunigt werden. Zur Erzeugung eines sogenannten Oszillationszustandes kann ein eine Verdichterwalze periodisch in Umfangsrichtung um eine Walzendrehachse hin und her beaufschlagendes Oszillationsdrehmoment generiert werden.In order to achieve a better compaction result in the compaction of ground, such as asphalt, soil or gravel, it is known, the static load of the substrate to be compacted by the weight of a rolling on this compressor roller or on this on the ground supported compressor to superimpose dynamic conditions of the compressor roller. Thus, a compressor roller for generating a so-called vibration state substantially vertically, ie in a direction substantially orthogonal to the surface of the substrate to be compacted, are periodically accelerated up and down. To generate a so-called oscillation state, a compression roller periodically oscillating in the circumferential direction around a roller rotation axis can be generated.

Es ist die Aufgabe der vorliegenden Erfindung, eine Verdichterwalze für einen Bodenverdichter vorzusehen, bei welcher eine erhöhte Variabilität bei der Erzeugung eines Oszillationsdrehmoments besteht.It is the object of the present invention to provide a compactor roller for a soil compactor, in which there is an increased variability in the generation of an oscillating torque.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Verdichterwalze für einen Bodenverdichter, umfassend einen eine Walzendrehachse konzentrisch umgebenden und einen Walzeninnenraum umschließenden Walzenmantel sowie zwei wenigstens teilweise in dem Walzeninnenraum angeordnete Oszillationsanordnungen zur Erzeugung eines den Walzenmantel beaufschlagenden Oszillationsdrehmoments bezüglich der Walzendrehachse, wobei jede Oszillationsanordnung wenigstens zwei um eine jeweilige Oszillationsdrehachse drehbare Oszillationsmasseneinheiten und wenigstens einen Oszillationsantriebsmotor zum Antreiben ausschließlich der Oszillationsmasseneinheiten dieser Oszillationsanordnung umfasst.According to the invention, this object is achieved by a compactor roller for a soil compactor, comprising a roll shell concentrically surrounding a roller rotation axis and a roll interior and two arranged at least partially in the roll interior Oszillationsanordnungen for generating the roll shell acting on the oscillation torque with respect to the roll rotation axis, each oscillation at least two to a respective oscillation rotational axis comprises rotatable Oszillationsmasseneinheiten and at least one Oszillationsantriebsmotor for driving only the Oszillationsmasseneinheiten this oscillatory arrangement.
Anders als bei der aus der
Dabei können die Oszillationsmasseneinheiten verschiedener Oszillationsanordnungen in Richtung der Walzendrehachse zueinander versetzt sein, vorzugsweise derart, dass sie einander in Richtung der Walzendrehachse nicht überlappen.In this case, the Oszillationsmasseneinheiten different oscillating arrangements can be offset in the direction of the roll rotation axis to each other, preferably such that they do not overlap each other in the direction of the roll axis of rotation.
Für eine kompakte Bauweise wird vorgeschlagen, dass bei wenigstens einer, vorzugsweise jeder Oszillationsanordnung wenigstens zwei Oszillationsmasseneinheiten einer Oszillationsmassenanordnung in Richtung der Walzendrehachse nicht zueinander versetzt sind. Dies bedeutet insbesondere, dass die Massenschwerpunkte dieser Oszillationsmasseneinheiten in Richtung der Walzendrehachse im Wesentlichen nicht zueinander versetzt sind, also beispielsweise in einer zur Walzendrehachse orthogonalen gemeinsamen Ebene liegen.For a compact design, it is proposed that in at least one, preferably each oscillation arrangement, at least two oscillation mass units of an oscillation mass arrangement in the direction of the roll rotation axis are not offset from each other. This means, in particular, that the centers of mass of these oscillating mass units are substantially not offset from one another in the direction of the roller rotational axis, that is, for example, lie in a common plane orthogonal to the roller rotational axis.
Um zu gewährleisten, dass bei den Oszillationsanordnungen in Umfangsrichtung bezüglich der Walzendrehachse wirkende Drehmomente generiert werden, wird vorgeschlagen, dass bei wenigstens einer, vorzugsweise jeder Oszillationsanordnung wenigstens zwei Oszillationsmasseneinheiten einander paarweise zugeordnet bezüglich der Walzendrehachse einander gegenüberliegend angeordnet sind, vorzugsweise mit einem Winkelabstand von 180°.In order to ensure that in the oscillatory arrangements in the circumferential direction with respect to the roll rotation axis acting torques are generated, is proposed that at least one, preferably each oscillation assembly at least two Oszillationsmasseneinheiten paired with respect to the roll rotation axis are arranged opposite each other, preferably with an angular distance of 180 °.
Um im Walzeninnenraum einen im Wesentlichen symmetrischen Aufbau bereitzustellen und somit auch eine definierte Zusammenwirkung der Oszillationsanordnungen unterstützen zu können, wird vorgeschlagen, dass die Oszillationsmasseneinheiten verschiedener Oszillationsmassenanordnungen derart bezüglich einander angeordnet sind, dass zu wenigstens einer, vorzugsweise jeder Oszillationsmasseneinheit einer Oszillationsmassenanordnung eine dazu koaxial angeordnete Oszillationsmasseneinheit der anderen Oszillationsanordnung vorgesehen ist.In order to provide a substantially symmetrical structure in the roller interior and thus to support a defined interaction of the Oszillationsanordnungen, it is proposed that the Oszillationsmasseneinheiten different Oszillationsmassenanordnungen are arranged with respect to each other, that at least one, preferably each Oszillationsmasseneinheit Oszillationsmassenanordnung a coaxial arranged Oszillationsmasseneinheit the other oscillation arrangement is provided.
Um im Betrieb einer erfindungsgemäß aufgebauten Verdichterwalze bzw. eines damit ausgestatteten Bodenverdichters die Wirkung der Oszillationsanordnungen definiert aufeinander abstimmen zu können, kann in Zuordnung zu jeder Oszillationsanordnung ein Drehlagesensor zur Bereitstellung von Information bezüglich der Drehlage der Oszillationsmasseneinheiten dieser Oszillationsanordnung vorgesehen sein. Ferner kann eine Ansteueranordnung vorgesehen sein zum Ansteuern der Oszillationsantriebsmotoren beruhend auf der durch die Drehlagesensoren bereitgestellten Information.In order to be able to coordinate the effect of the oscillating arrangements in the operation of a compactor roller constructed in accordance with the invention, a rotational position sensor for providing information regarding the rotational position of the oscillating mass units of this oscillating arrangement can be provided in association with each oscillation arrangement. Further, a drive arrangement may be provided for driving the oscillation drive motors based on the information provided by the rotational position sensors.
Insbesondere dann, wenn bei jeder Oszillationsanordnung ein einziger Oszillationsantriebsmotor vorgesehen ist, um die Oszillationsmasseneinheiten dieser Oszillationsanordnung zur Drehung anzutreiben, wird zur antriebsmäßigen Kopplung vorgeschlagen, dass bei wenigstens einer, vorzugsweise jeder Oszillationsanordnung ein Riementrieb zum Antreiben der Oszillationsmasseneinheiten dieser Oszillationsanordnung zur Drehung um deren Oszillationsdrehachsen vorgesehen ist.In particular, when a single oscillation drive motor is provided in each oscillation arrangement to drive the Oszillationsmasseneinheiten this oscillatory arrangement for rotation, it is proposed for driving coupling, that at least one, preferably each oscillation arrangement, a belt drive for driving the Oszillationsmasseneinheiten this oscillation arrangement for rotation about their Oszillationsdrehachsen provided is.
Bei einer besonders bevorzugten Ausgestaltungsform wird vorgeschlagen, dass eine der Oszillationsanordnungen im Wesentlichen in einem Längenhälftenbereich des Walzeninnenraums angeordnet ist und die andere Oszillationsanordnung im anderen Längenhälftenbereich des Walzeninnenraums angeordnet ist. Somit erzeugt jede der Oszillationsanordnungen das von dieser bereitzustellende Oszillationsdrehmoment in dem diese jeweils aufnehmenden Längenhälftenbereich des Walzeninnenraums, also in unterschiedlichen axialen Bereichen der Verdichterwalze. Da der mit den so erzeugten Oszillationsdrehmomenten beaufschlagte Walzenmantel in sich sehr steif ist, führt die Beaufschlagung mit beispielsweise phasenverschoben wirkenden Drehmomenten in unterschiedlichen axialen Bereichen des Walzenmantels nicht zu einer Beeinträchtigung der Funktionalität bzw. der Betriebscharakteristik des Walzenmantels bzw. der Verdichterwalze.In a particularly preferred embodiment, it is proposed that one of the oscillatory arrangements be located substantially in a length-halved area of the Roller interior is arranged and the other oscillation arrangement is arranged in the other longitudinal half portion of the roller interior. Thus, each of the oscillating arrangements generates the oscillation torque to be provided by the latter in the respective length halves area of the roller interior, ie in different axial areas of the compressor roller. Since the roll jacket which is acted upon by the oscillation torques thus produced is very stiff in itself, the application of torques which, for example, have a phase shift effect in different axial regions of the roll shell does not impair the functionality or the operating characteristic of the roll shell or the compacting roll.
Um eine gegenseitige Beeinträchtigung zu vermeiden, wird vorgeschlagen, dass die Oszillationsanordnungen einander in Richtung der Walzendrehachse nicht überlappen.In order to avoid mutual interference, it is proposed that the oscillatory arrangements do not overlap one another in the direction of the roller rotation axis.
Die Erfindung betrifft ferner einen Bodenverdichter, umfassend wenigstens eine Verdichterwalze mit einem vorangehend beschriebenen Aufbau.The invention further relates to a soil compactor comprising at least one compacting roller having a structure as described above.

Die
In jedem der beiden Längenhälftenbereiche L1, L2 ist jeweils eine Oszillationsanordnung 28, 30 angeordnet. Die beiden Oszillationsanordnungen 28, 30 können zueinander im Wesentlichen baugleich sein und umfassen einen zur Walzendrehachse W beispielsweise konzentrisch angeordneten Oszillationsantriebsmotor 32, 34 jeweils mit einer zur Walzendrehachse W vorzugsweise konzentrischen Antriebswelle 36, 38. Beispielsweise können die beiden Oszillationsantriebsmotoren 32, 34 als Hydraulikmotoren ausgebildet sein.In each of the two length halves areas L 1 , L 2 each have an
Jede Oszillationsanordnung 28, 30 umfasst ferner zwei bezüglich der Walzendrehachse exzentrisch angeordnete Oszillationsmasseneinheiten 40, 42 bzw. 44, 46. Jede Oszillationsmasseneinheit 40, 42, 44, 46 umfasst, wie nachfolgend mit Bezug auf die
Zum Antrieb der jeweiligen Oszillationsmasseneinheiten 40, 42 bzw. 44, 46 kann jede der Oszillationsanordnungen 28, 30 einen allgemein mit 48 bzw. 50 bezeichnete Riementrieb umfassen. Dieser kann jeweils einen oder mehrere über jeweilige Riemenscheiben mit der jeweiligen Antriebswelle 36, 38 bzw. den Oszillationsmasseneinheiten 40, 42, 44, 46 zusammenwirkende Antriebsriemen, beispielsweise Zahnriemen, umfassen.To drive the
In Zuordnung zu jeder Oszillationsanordnung 28, 30 ist zumindest ein Drehlagesensor 52, 54 vorgesehen. Dieser kann beispielsweise am jeweiligem Oszillationsantriebsmotor 32 bzw. 34 vorgesehen sein und die Drehlage eines Rotors, beispielsweise der jeweiligen Antriebswelle 36, 38, erfassen, wodurch auch Information über die Drehlage der jeweiligen Unwuchtmasseneinheiten 40, 42 bzw. 44, 46 bzw. der daran jeweils vorgesehenen Unwuchtmassen erhalten wird. Diese Drehlageinformation wird in eine allgemein mit 56 bezeichnete Ansteueranordnung eingespeist. Die Ansteueranordnung 56 kann unter Berücksichtigung dieser Drehlageinformation die Oszillationsantriebsmotoren 32, 34 der beiden Oszillationsanordnungen 28, 30 ansteuern, um diese mit bestimmter Drehzahl und bestimmter Phasenlage bezüglich einander zu betreiben. Dabei wird durch jede der Oszillationsanordnungen 28, 30 ein die Verdichterwalze 22 bzw. den Walzenmantel 26 in Umfangsrichtung um die Walzendrehachse W beaufschlagendes bzw. beschleunigendes Oszillationsdrehmoment generiert. Je nach Phasenlage der durch die beiden Oszillationsanordnungen 28, 30 erzeugten Oszillationsdrehmomente können diese einander konstruktiv oder destruktiv überlagert werden, um somit beispielsweise bei maximaler konstruktiver Überlagerung der beiden durch die Oszillationsanordnungen 28, 30 generierten Oszillationsdrehmomente ein Gesamt-Oszillationsdrehmoment auf den Walzenmantel 22 auszuüben, welches der Summe der beiden Oszillationsdrehmomente entspricht, also beispielsweise dem Doppelten von dem durch eine jeweilige Oszillationsanordnung 28, 30 generierten Oszillationsdrehmoment, wenn die durch die beiden Oszillationsanordnungen 28, 30 generierten Oszillationsdrehmomente im Wesentlichen gleich groß sind. Bei maximaler destruktiver Überlagerung liegt das resultierende Gesamt-Oszillationsdrehmoment im Bereich von Null. Durch Einstellung bzw. Veränderung der Phasenlage der Oszillationsdrehmomente der beiden Oszillationsanordnungen 28, 30 bezüglich einander wird somit das erreichbare Gesamt-Oszillationsdrehmoment in diesem Spektrum einstellbar.In association with each

Es sei darauf hingewiesen, dass, abhängig von der Baugröße der Oszillationsanordnungen 28, 30 bzw. der Verdichterwalze 22, beispielsweise die Oszillationsantriebsmotoren 32, 34 in Richtung der Walzendrehachse axial über den Walzeninnenraum 58 bzw. den Walzenmantel 26 hervorstehen können, insbesondere mit Bereichen, in welchen diese an ein Hydrauliksystem eines Bodenverdichters anzuschließen sind. Dies bedeutet jedoch im Sinne der vorliegenden Erfindung nicht, dass eine derartige Oszillationsanordnung dann nicht im Wesentlichen in einem jeweils zugeordneten Längenhälftenbereich des Walzeninnenraums bzw. der Verdichterwalze angeordnet wäre.It should be noted that, depending on the size of the

Die Antriebswelle 38 des Oszillationsantriebsmotors 52 kann über zwei diese drehbar aufnehmende Lagerscheiben 64 an im Walzeninnenraum vorgesehenen Trägern, wie sie vorangehend mit Bezug auf die
Im Antriebszustand wird das durch den Oszillationsantriebsmotor 32 generierte Antriebsdrehmoment über die Antriebswelle 38 und die beiden Riemen 70, 72 auf die Unwuchtwellen 78, 80 der beiden Oszillationsmasseneinheiten 40, 42 übertragen, so dass die Unwuchtwellen 78, 80 um die Oszillationsdrehachsen O1, O2 rotieren.In the drive state, the drive torque generated by the
Jede der beiden Oszillationsmasseneinheiten 40, 42 umfasst an der jeweiligen Unwuchtwelle 78, 80 zwei in axialem Abstand zueinander angeordnete Unwuchtmassen 86, 88. Deren Massenschwerpunkt liegt zur jeweiligen Oszillationsdrehachse O1 bzw. O2 exzentrisch, wobei beispielsweise bei jeder der Unwuchtmasseneinheiten 40, 42 die dort jeweils vorgesehenen Unwuchtmassen 86, 88 so angeordnet sein können, dass deren Massenschwerpunkte in Bezug auf die jeweilige Oszillationsdrehachse O1 bzw. O2 im gleichen Umfangsbereich liegen. Somit ergibt sich bei jeder Oszillationsmasseneinheit 40, 42 ein Gesamt-Massenschwerpunkt der beiden Unwuchtmassen 86, 88, der in Richtung der jeweiligen Oszillationsdrehachse O1, O2 näherungsweise mittig zwischen den beiden Unwuchtmassen 86, 88 der jeweiligen Oszillationsmasseneinheit 40, 42 liegen kann. Dabei ist die Anordnung vorzugsweise derart, dass die beiden Gesamt-Massenschwerpunkte der beiden Unwuchtmasseneinheiten 40, 42 in einer zur Walzendrehachse W orthogonalen, gemeinsamen Ebene liegen. Es sei darauf hingewiesen, dass selbstverständlich bei den Unwuchtmasseneinheiten 40, 42 jeweils eine andere Anzahl an Unwuchtmassen vorgesehen sein könnte. So könnte beispielsweise eine einzige Unwuchtmasse vorgesehen sein, deren Massenschwerpunkt dann im Wesentlichen auch die axiale Lage des Massenschwerpunkts einer jeweiligen Unwuchtmasseneinheit definiert.Each of the two
Man erkennt in
Es sei abschießend darauf hingewiesen, dass, ohne von den Prinzipien der vorliegenden Erfindung abzuweichen, die vorangehend beschriebene Verdichterwalze in verschiedenster Weise variiert werden kann. So könnten bei entsprechender Baugröße der Verdichterwalze auch mehr als zwei voneinander unabhängig betreibbare und beispielsweise in Richtung der Walzendrehachse aufeinanderfolgende Oszillationsanordnungen vorgesehen sein. Jede Oszillationsanordnung könnte auch mehr als zwei Oszillationseinheiten aufweisen, beispielsweise vier Oszillationseinheiten, wobei dann jeweils paarweise einander zugeordnet zwei Oszillationseinheiten bezüglich der Walzendrehachse einander gegenüberliegend mit einem Winkelversatz von 180° angeordnet sind. Derartige Paare von Oszillationseinheiten einer Oszillationsanordnung können im gleichen axialen Bereich, also nebeneinander liegend, angeordnet sein, könnten aber auch axial zueinander versetzt bzw. axial aufeinander folgend angeordnet sein. Ferner könnten bei den Oszillationsanordnungen insbesondere dann, wenn diese mehr als zwei Oszillationseinheiten aufweisen, mehrere Oszillationsantriebsmotoren vorgesehen sein, so dass beispielsweise bei jeder Oszillationsanordnung jede Oszillationseinheit oder zumindest jedes Paar von Oszillationseinheiten einen nur diese bzw. dieses zur Drehung antreibenden Oszillationsantriebsmotor aufweist. Auch dabei wird die erfindungsgemäße Anordnung beibehalten, bei welcher verschiedene Oszillationsanordnungen grundsätzlich baulich und funktional voneinander getrennt sind, also für sich eigenständig antreibbar sind, selbstverständlich in Abstimmung aufeinander. Ein jeweiliger Oszillationsantriebsmotor kann grundsätzlich auch als Elektromotor ausgebildet sein. Ferner können die Oszillationsmassenanordnungen auch über andere Getriebeanordnungen, beispielsweise Zahnradgetriebe, vermittels eines jeweils zugeordneten Oszillationsantriebsmotors zur Drehung angetrieben werden.It should be noted that, without departing from the principles of the present invention, the compactor roller described above can be varied in a variety of ways. Thus, with a corresponding size of the compactor roller, more than two oscillatory arrangements which can be operated independently of one another and, for example, in the direction of the roller rotational axis could be provided. Each oscillation arrangement could also have more than two oscillation units, for example four oscillation units, in which case two oscillation units associated with each other are arranged opposite one another with an angular offset of 180 ° with respect to the roller rotation axis. Such pairs of oscillation units of an oscillation arrangement can be arranged in the same axial region, ie lying next to each other, but could also be axially offset from one another or arranged axially one after the other. Furthermore, in the case of the oscillatory arrangements, in particular if these have more than two oscillation units, a plurality of oscillation drive motors could be provided, so that, for example, in each oscillation arrangement, each oscillation unit or at least each pair of oscillation units has an oscillation drive motor driving only this or this for rotation. Here, too, the arrangement according to the invention is maintained, in which different oscillatory arrangements are fundamentally structurally and functionally separated from each other, that is to say they can be driven independently, of course in coordination with one another. A respective oscillation drive motor can in principle also be designed as an electric motor. Furthermore, the Oszillationsmassenanordnungen can be driven via other gear arrangements, such as gear transmission, by means of a respective associated Oszillationsantriebsmotors for rotation.
Bei einer weiteren, den Prinzipien der vorliegenden Erfindung unterzuordnen Ausgestaltung könnten die Oszillationsmasseneinheiten verschiedener Oszillationsanordnungen nebeneinander, somit einander axial überlappend angeordnet sein, so dass beispielsweise ein Paar von bezüglich der Walzendrehachse sich einander gegenüberliegenden Oszillationsmasseneinheiten einer der Oszillationsanordnungen bezüglich einem Paar bezüglich der Walzendrehachse sich einander gegenüberliegender Oszillationsmasseneinheiten der anderen Oszillationsanordnung einen Winkelabstand von beispielsweise 90° aufweist. Die den verschiedenen Oszillationsanordnungen zugeordneten Oszillationsmasseneinheiten sind wiederum durch ausschließlich diese zur Drehung antreibende, separate Oszillationsantriebsmotoren zur Drehung antreibbar, so das jede der Oszillationsanordnungen das durch diese bereitzustellende Oszillationsdrehmoment unabhängig von der jeweils anderen Oszillationsanordnung erzeugen kann.In a further embodiment, which is subordinate to the principles of the present invention, the oscillation mass units of different oscillation arrangements could coexist, thus axially overlapping one another so that, for example, a pair of oscillation mass units of one of the oscillation assemblies with respect to the roll rotation axis have an angular distance of, for example, 90 ° with respect to a pair of oscillation mass units of the other oscillation assembly with respect to the roll rotation axis. The Oszillationsanordnungen associated oscillation mass units are in turn driven by only these driving to rotate, separate Oszillationsantriebsmotoren for rotation, so that each of the Oszillationsanordnungen can provide the to be provided by these oscillating torque regardless of the other oscillatory arrangement.
