Description

Die Erfindung betrifft einen Straßenfertiger gemäß Oberbegriff des Anspruchs 1.The invention relates to a road paver according to the preamble of claim 1.

In einem Straßenfertiger gibt es elektrische Verbraucher, unter denen die Heizeinrichtungen für die Glättbleche, Tamper und dgl. in der Einbaubohle durchaus nennenswerten Stromverbrauch haben. Deshalb ist im Straßenfertiger ein großer und schwerer Generator notwendig, der bei bekannten Straßenfertigern dicht neben dem das Primärantriebsaggregat bildenden Dieselmotor angeordnet, gegebenenfalls an diesem gelagert, und von der Kurbelwelle des Dieselmotors direkt über einen Riementrieb angetrieben wird. In der Praxis zeigt sich, dass die Belastung der Kurbelwelle durch den Riementrieb unerwünscht hoch werden kann. Alternativ ist es bekannt, den Generator von dem Primärantriebsaggregat getrennt durch einen eigenen Hydraulikmotor anzutreiben. Abgesehen davon, dass dann der Generator mit seinem Hydraulikmotor exponiert, z.B. auf der Einbaubohle platziert werden muss, ist dieses Antriebsprinzip im praktischen Gebrauch eine häufige Störungsquelle.In a paver, there are electrical consumers, among which the heaters for the screed plates, tamper and the like. In the screed have quite significant power consumption. Therefore, in the paver a large and heavy generator is necessary, which is arranged close to the primary drive unit forming diesel engine in known road pavers, optionally mounted on this, and is driven by the crankshaft of the diesel engine directly via a belt drive. In practice, it has been found that the load on the crankshaft through the belt drive can become undesirably high. Alternatively, it is known to drive the generator separated from the prime mover by its own hydraulic motor. Apart from that then the generator exposed with its hydraulic motor, e.g. must be placed on the screed, this drive principle in practical use is a frequent source of interference.

Bei dem aus EP 0 489 969 B1 bekannten Straßenfertiger ist der Generator mit seiner Eingangswelle fluchtend zur Kurbelwelle des Dieselmotors angeordnet und mit seinem Gehäuse mit dem Dieselmotor zusammengeflanscht. Zwischen der Kurbelwelle des Dieselmotors und der Antriebswelle des Generators ist eine mechanische Verbindung vorgesehen. Bei einer Ausführungsform durchsetzt die mechanische Verbindung ein Getriebe, von dem ein Nebenabtrieb zu einem Pumpenverteilergetriebe abzweigt. Das Getriebe ermöglicht unterschiedliche Drehzahlen der Kurbelwelle und des Generators. Da der Antriebsstrang von der Kurbelwelle direkt zum Generator verläuft, lassen sich vom Generatorantrieb herrührende Störungen nicht vermeiden und sind auch keine Relativbewegungen zwischen dem Generator und dem Dieselmotor möglich.At the EP 0 489 969 B1 known paver, the generator is arranged with its input shaft in alignment with the crankshaft of the diesel engine and flanged together with its housing with the diesel engine. Between the crankshaft of the diesel engine and the drive shaft of the generator, a mechanical connection is provided. In one embodiment, the mechanical connection passes through a transmission from which a power take-off branches off to a pump transfer case. The transmission allows different speeds of the crankshaft and the generator. Since the drive train runs from the crankshaft directly to the generator, disturbances resulting from the generator drive can not be avoided and no relative movements between the generator and the diesel engine are possible.

Aus DE 28 08 437 A ist ein Fahrzeug mit einem Arbeitsgerät und insbesondere mit, einem Abfräs- oder Aufreiß-Gerät für verschlissene Fahrbahn-Oberschichten bekannt. Das Fahrzeug weist eine als Sattelschlepper ausgebildete Zugmaschine mit einem Sattelauflieger für das aufgesetzte Gerät auf. Von der Primärantriebsquelle des Sattelschleppers zweigen sich zwei zu- und abschaltbare Antriebsstränge auf. Ein Hauptantriebsstrang führt über ein Schaltgetriebe einerseits zu einem Verteilergetriebe für die Vorderachse und/oder Hinterachse des Sattelschleppers und andererseits über eine Gelenkwelle zu einem Planetengetriebe mit angeflanschtem Ölmotor. Der Ölmotor treibt bei langsamer Arbeitsfahrt über das Planetengetriebe beispielsweise die Hinterachse, während das Hauptantriebsstrang abgeschaltet ist. Der Nebenantriebsstrang führt über eine Gelenkwelle zu einem auf dem Rahmen des Sattelschleppers montierten Pumpenverteilergetriebe, an dessen Antriebsausgängen Ölpumpen, einschließlich einer Ölpumpe für den Ölmotor, angeflanscht sind. Bei einer Ausführungsform wird anstelle der Ölpumpe für den Ölmotor ein Generator direkt an einen Antriebsausgang des Pumpenverteilergetriebes angeflanscht, und wird am Planetengetriebe anstatt des Ölmotors ein Elektromotor montiert, der vom Generator mit elektrischer Leistung versorgt wird und bei langsamer Arbeitsfahrt z.B. die Hinterachse des Sattelschleppers antreibt.Out DE 28 08 437 A is a vehicle with a working device and in particular with, a Abfräs- or tearing device for worn road surface layers known. The vehicle has a tractor designed as a tractor tractor with a semi-trailer for the patch device. From The primary drive source of the semitrailer tractor is equipped with two drive trains which can be switched on and off. A main drive train leads via a manual transmission on the one hand to a transfer case for the front axle and / or rear axle of the semitrailer and on the other hand via a propeller shaft to a planetary gear with flanged oil motor. For example, the oil engine drives the rear axle while the main drivetrain is off while the work travel is slow. The PTO leads via a PTO shaft to a mounted on the frame of the semitrailer pump distributor gearbox at the drive outputs oil pumps, including an oil pump for the oil engine, are flanged. In one embodiment, instead of the oil pump for the oil engine, a generator is flanged directly to a drive output of the pump transfer case, and an electric motor is mounted on the planetary gear instead of the oil motor, which is supplied by the generator with electrical power and drives at slower working drive, for example, the rear axle of the tractor.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Straßenfertiger einen erweiterten Freiheitsgrad zur Unterbringung des Generators im Hindlick auf die gegebenen Einbaumöglichkeiten zu erreichen, und vom Generatorantrieb verursachte Störungen zu minimieren.The invention has for its object to achieve in a paver an extended degree of freedom to accommodate the generator in hindsight on the given installation options, and to minimize interference caused by the generator drive.

Die gestellte Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst.The stated object is achieved with the features of claim 1.

In Abkehr vom herkömmlichen Prinzip wird der Generator unabhängig von der Primärantriebquelle dort platziert, wo es nach den Einbaumöglichkeiten und auch im Hinblick auf die Wartungsfreundlichkeit zweckdienlich ist, und wird der Generator von dem Pumpenverteilergetriebe angetrieben. Der Generator ist nicht nur von Vibrationen des Primärantriebs freigestellt, sondern es lässt sich zum Antrieb des Generators gegebenenfalls eine andere Drehzahl nutzen als die der Kurbelwelle der Primärantriebsquelle, was für das Leistungsverhalten des Generators günstig ist. Das Pumpenverteilergetriebe wird zwar von der Kurbelwelle des Dieselmotors des Primärantriebsaggregats angetrieben, jedoch sind schädliche Belastungen der Kurbelwelle vermieden. Auf baulich einfache Weise wird der Generator über einen Riementrieb mit einem Antriebsausgang des Pumpengetriebes gekuppelt. Ein solcher kuppelnder Riementrieb baut klein und ist bequem zu warten und zu überprüfen. Alternativ lässt sich der Generator über eine Hohlwelle direkt vom Pumpenverteilergetriebe antreiben. Als weitere Alternative ist zwischen dem Generator und dem Pumpenverteilergetriebe eine Kupplung oder eine Gelenkwelle vorgesehen. Damit, und da der Generator mit einer Lagerung auf dem Pumpenverteilergetriebe oder mit eigenen Lagerungen im Chassis getrennt vom Pumpenverteilergetriebe abgestützt ist, lassen sich Montageungenauigkeiten oder Relativbewegungen zwischen den gekoppelten Aggregaten kompensieren.Contrary to the conventional principle, the generator is placed where it is appropriate for the installation options and also with regard to serviceability, independently of the primary drive source, and the generator is driven by the pump distributor gearbox. The generator is not only exempt from vibrations of the prime mover, but it can be used to drive the generator optionally a different speed than that of the crankshaft of the primary drive source, which is favorable for the performance of the generator. The pump transfer case is Although driven by the crankshaft of the diesel engine of the prime mover, but harmful loads on the crankshaft are avoided. In a structurally simple way, the generator is coupled via a belt drive with a drive output of the pump gearbox. Such a coupling belt drive builds small and is convenient to maintain and check. Alternatively, the generator can be driven via a hollow shaft directly from the pump distributor gearbox. As a further alternative, a coupling or a propeller shaft is provided between the generator and the pump distributor gear. Thus, and as the generator is supported by a bearing on the pump transfer case or with its own bearings in the chassis separately from the pump transfer case, assembly inaccuracies or relative movements between the coupled units can be compensated.

Um den Generator mit der für ihn günstigsten Drehzahl anzutreiben, ist es zweckmäßig, im Pumpenverteilergetriebe oder zwischen dem Pumpenverteilergetriebe und dem Generator eine feste oder variable Drehzahlüber- oder -untersetzung vorzusehen.In order to drive the generator at the most favorable speed for it, it is expedient to provide a fixed or variable Drehzahlüber- or -untersetzung in Pumpenverteilergetriebe or between the pump distributor gearbox and the generator.

Wenn der Generator über eine Lagerung auf dem Pumpenverteilergetriebe abgestützt und von einem Abtriebsausgang des Pumpenverteilergetriebes über einen Riementrieb angetrieben wird, kann es zweckmäßig sein, das Pumpenverteilergetriebe mit eigenen Lagerungen im Chassis des Straßenfertigers abzustützen.If the generator is supported by a bearing on the pump transfer case and driven by a driven output of the pump transfer case via a belt drive, it may be appropriate to support the pump transfer case with their own bearings in the chassis of the paver.

schematically further detail variants.

Ein Straßenfertiger F in der Fig. 1 weist ein Chassis 1 auf, an dem in Arbeitsfahrtrichtung vorne ein Gutbunker B und hinter diesem eine Primärantriebsquelle P vor einem Führerstand A angeordnet sind. Den Boden des Führerstands A bildet eine Plattform 2, die einen Aufbau trägt, an dem um eine quer zur Längsrichtung verlaufende, hochliegende Gelenkachse 18 eine Abdeckung 3 der Primärantriebsquelle P mit ihrem vorderen Unterrand 16 in Richtung eines Pfeils 19 hochschwenkbar angeordnet ist. Die Plattform 2 ihrerseits ist zusammen mit der daran angebrachten Abdeckhaube 3 als eine Einheit um eine am Chassis hinten und quer liegende Achse 15 hochschwenkbar, derart, dass der Vorderrand 16 in Richtung eines Pfeils 17 nach oben verlagerbar ist. Die Primärantriebsquelle P ist ein Dieselmotor M.A paver F in the Fig. 1 has a chassis 1, at the front in working direction a Gutbunker B and behind this a primary drive source P in front of a cab A are arranged. The bottom of the cab A forms a platform 2, which carries a structure on which a cover 3 of the primary drive source P with its front lower edge 16 in the direction of an arrow 19 is arranged swung up about a transversely extending to the longitudinal axis, hinge axis 18. The platform 2, in turn, together with the cover 3 attached thereto, can be pivoted up as a unit about an axis 15 on the chassis rear and transverse, such that the front edge 16 is displaceable upward in the direction of an arrow 17. The prime mover source P is a diesel engine M.

Der Gutbunker B weist eine Bunkerrückwand 4 und Bunkerseitenwände 5 auf, die um unten liegende, annähernd zur Längsrichtung des Straßenfertigers parallele Achsen 8 in die gestrichelte Transportstellung 5' einwärts schwenkbar sind.The Gutbunker B has a bunker rear wall 4 and Bunkerseitenwände 5, which are at the bottom, approximately parallel to the longitudinal direction of the paver axes 8 in the dashed transport position 5 'inwardly pivotable.

Im Chassis 1 ist eine Längsfördervorrichtung C für Einbaugut vorgesehen. Hinten ist eine Querverteilvorrichtung Q montiert. Der Gutbunker B wird über eine Einfüllkante beschickt. Die Längsfördervorrichtung C weist z.B. ein oder zwei Kratzerbänder (oder Längsförderschnecken oder Förderbänder) auf, zwischen denen eine längsverlaufende Abdeckung 7 vorgesehen ist.In the chassis 1, a longitudinal conveyor C is provided for built-in. At the rear, a transverse distribution device Q is mounted. The Gutbunker B is fed via a filling edge. The longitudinal conveyor C has e.g. one or two scraper belts (or longitudinal screw conveyors or conveyor belts), between which a longitudinal cover 7 is provided.

Im Gutbunker B ist wenigstens eine in eine Wartungsstellung (in Fig. 1 gestrichelt) bringbare Personenstandfläche WP vorgesehen, die wegnehmbar oder zumindest in eine Position verstellbar ist, in der sie die Funktion des Gutbunkers nicht beeinträchtigt. Beispielsweise ist die Personenstandfläche WP von einer mit einer Trittauflage 9 ausgestatteten Wartungsklappe K gebildet, die in einem unten liegenden Scharnier oder Beschlägen an der Bunkerrückwand 4 angeschlagen und in Richtung des gestrichelten Pfeiles schwenkbar ist. Gegebenenfalls ist eine Gewichtsentlastungsvorrichtung H wie eine Gasfeder oder eine Zugfeder vorgesehen. In der Wartungsstellung liegt die Personenstandfläche WP in etwa horizontal oder leicht nach vorne unten schräg geneigt. In geschlossener Stellung ist die Wartungsklappe K mit einem Riegel an der Bunkerrückwand festgelegt (ggfs. sogar versperrt).In Gutbunker B at least one in a maintenance position (in Fig. 1 dashed line) provided personal standing area WP, which is wegnehmbar or at least adjustable in a position in which it does not affect the function of Gutbunkers. For example, the personal standing area WP is formed by a service flap K provided with a footrest 9, which is struck in a lower hinge or fittings on the bunker rear wall 4 and can be pivoted in the direction of the dashed arrow. Optionally, a weight relief device H as a gas spring or a tension spring is provided. In the maintenance position, the person standing area WP is approximately horizontal or slightly inclined forward and downwards. In the closed position, the maintenance flap K is fixed with a bolt on the bunker rear wall (possibly even locked).

Im von der Personenstandfläche WP zugänglichen Bereich hinter der Bunkerrückwand 4 sind bewusst wartungsbedürftige Komponenten G des Straßenfertigers F angeordnet, beispielsweise Batterien 10, Kühlmittel-, Schmierstoff- oder Hydraulik-Einfüll- oder Überwachungseinrichtungen 11 und dgl. Ferner sind in Fig. 1 ein Pumpenverteilergetriebe 12 als ein Nebenabtrieb N und ein darauf angebrachter Generator D in diesem Bereich angeordnet, wobei die Antriebswelle des Generators D über einen Riementrieb 13 mit einer Ausgangswelle des Pumpenverteilergetriebes 12 gekuppelt ist. Das Pumpenverteilergetriebe 12 kann mit eigenen Lagerungen 24 im Chassis abgestützt sein und wird auf herkömmliche Weise von der Primärantriebsquelle P bzw. der Kurbelwelle W angetrieben. Seitlich sind in der Abdeckhaube 3 wenigsten eine Wartungs- oder Kühlöffnung 14 vorgesehen.In the area accessible from the civil standing area WP behind the bunker rear wall 4, maintenance-requiring components G of the paver F are deliberately arranged, for example batteries 10, coolant, lubricant or hydraulic filling or monitoring devices 11 and the like Fig. 1 a pump distributor gear 12 as a power take-off N and a generator mounted thereon D arranged in this area, wherein the drive shaft of the generator D is coupled via a belt drive 13 with an output shaft of the pump distributor gear 12. The pump transfer case 12 may be supported by its own bearings 24 in the chassis and is driven in a conventional manner by the primary drive source P and the crankshaft W, respectively. At least one maintenance or cooling opening 14 are provided laterally in the cover 3.

Die Anordnung des das Pumpenverteilergetriebe 12 darstellenden Nebenabtriebs N etwa in Verlängerung der Kurbelwelle W des die Primärantriebsquelle P bildenden Dieselmotors M mit dem beispielsweise auf dem Pumpenverteilergetriebe 12 mit einer eigenen Lagerung 26 abgestützten Generator D und dessen Riementrieb 13 sind in Fig. 2 schematisch herausgelöst gezeigt. Der Generator D nimmt keinen Einfluss auf die Kurbelwelle W. Er kann über einen Ausgang des Pumpenverteilergetriebes 12 mit einer für seinen Leistungscharakteristik günstigen Drehzahl angetrieben werden. Mit dem Pumpenverteilergetriebe 12 sind nicht gezeigte Hydraulikpumpen oder Hydraulikmotoren in Abtriebsverbindung.The arrangement of the power take-off N representing the pump distributor gear 12 approximately in extension of the crankshaft W of the primary drive source P forming diesel engine M with the example supported on the pump distributor gear 12 with its own bearing 26 generator D and the belt drive 13 are in Fig. 2 shown schematically removed. The generator D has no influence on the crankshaft W. It can be driven via an output of the pump distributor 12 with a favorable for its performance characteristics speed. With the pump distributor gearbox 12 are not shown hydraulic pumps or hydraulic motors in output connection.

Der Generator D könnte in Fig. 2 auch getrennt vom Pumpenverteilergetriebe 12 im Chassis 1 gelagert sein. Seine Antriebsachse muss nicht notwendigerweise parallel zur Kurbelwelle W liegen.The generator D could be in Fig. 2 be stored separately from the pump distributor 12 in the chassis 1. Its drive axle does not necessarily have to be parallel to the crankshaft W.

In Fig. 3 ist ein anderes Antriebsprinzip angedeutet. Das Pumpenverteilergetriebe 12 wird in herkömmlicher Weise von der Kurbelwelle W des Dieselmotors M angetrieben. Der von dem Pumpenverteilergetriebe 12 getrennte Generator D ist mit eigenen Lagerungen 26' im Chassis 1 gelagert und wird beispielsweise über eine Hohlwelle 27 vom Pumpenverteilergetriebe 12 direkt angetrieben. Anstelle einer Hohlwelle 27 könnte in diesem Bereich auch eine Kupplung oder Gelenkwelle vorgesehen sein, die nicht nur eine leichte Trennung von Pumpenverteilergetriebe 12 und Generator D im Falle einer Demontage einer dieser Komponenten ermöglicht, sondern auch Relativbewegungen und Montageungenauigkeiten kompensiert. Eine Gelenkwelle könnte auch eine versetzte oder winkelige Relativlage zwischen dem Pumpenverteilergetriebe 12 und dem Generator D ermöglichen. Der Generator D ist in Anpassung an die Einbaumöglichkeiten im Chassis angeordnet.In Fig. 3 another driving principle is suggested. The pump transfer case 12 is conventionally driven by the crankshaft W of the diesel engine M. The separate from the pump distributor gearbox 12 generator D is mounted with its own bearings 26 'in the chassis 1 and is driven directly, for example via a hollow shaft 27 from the pump distributor gear 12. Instead of a hollow shaft 27 could be provided in this area, a clutch or propeller shaft, not only a slight separation of pump distributor gear 12 and generator D in the event of disassembly of a allows these components, but also compensates for relative movements and assembly inaccuracies. An articulated shaft could also allow for a staggered or angular relative position between the pump distributor 12 and the generator D. The generator D is arranged in adaptation to the installation possibilities in the chassis.

In der linken Hälfte von Fig. 3 ist angedeutet, dass der Generator D an einer anderen Seite des Dieselmotors M mit eigenen Lagerungen 26', beispielsweise im Chassis, abgestützt ist und über einen aus dem Dieselmotor M getrennt von dessen Kurbelwelle W herausgeführten Nebenabtrieb N' und beispielsweise über eine Kupplung oder eine Gelenkwelle 27 von dem Nebenabtrieb N' angetrieben wird. Gegebenenfalls ist im Nebenabtrieb oder zwischen dem Nebenabtrieb und dem Generator D eine feste oder variable Drehzahlunter- oder Übersetzung 28 vorgesehen, um den Generator mit der für ihn günstigsten Drehzahl anzutreiben.In the left half of Fig. 3 is indicated that the generator D is supported on another side of the diesel engine M with its own bearings 26 ', for example in the chassis, and via a separate from the diesel engine M from the crankshaft W led out power take-off N' and for example via a clutch or a propeller shaft 27 is driven by the power take-off N '. Optionally, a fixed or variable Drehzahlunter- or translation 28 is provided in the power take-off or between the power take-off and the generator D to drive the generator with the most favorable speed for him.

In jedem Fall lassen sich für den Generator die Einbaumöglichkeiten im Chassis besser nutzen, wenn der Generator nicht direkt von der Kurbelwelle des Dieselmotors angetrieben wird, sondern über das Pumperverteilergetriebe 12.In any case, for the generator, the installation possibilities in the chassis can be better used if the generator is not driven directly by the crankshaft of the diesel engine, but via the Pumperverteilergetriebe 12th
