Description

Die Erfindung betrifft eine Baumaschine zum Bearbeiten von Bodenoberflächen nach dem Oberbegriff des Anspruchs 1.The invention relates to a construction machine for processing ground surfaces according to the preamble of claim 1.

Derartige Baumaschinen, zum Beispiel Großfräsen oder Kaltfräsen, weisen einen Maschinenrahmen auf, in dem eine quer zu der zu bearbeitenden Fahrspur verlaufende Fräswalze drehbar gelagert ist. Der Maschinenrahmen nimmt ferner noch den Fräswalzenantrieb auf und wird von mehreren vorzugsweise vor und hinter der Fräswalze angeordneten Fahrschiffen eines Fahrwerks höhenverstellbar getragen.Such construction machines, for example, large milling or cold milling machines, have a machine frame in which a transverse to the lane to be processed running milling drum is rotatably mounted. The machine frame also still takes on the milling drum drive and is supported by several preferably arranged in front of and behind the milling drum of a chassis height adjustable.

Derartige Groß- oder Kaltfräsen, bzw. Recycler werden zum Abfräsen von Straßenbelägen, zum Beispiel auf Autobahnen oder Landstraßen eingesetzt. Die Fräswalzen sind auf ihrer Mantelfläche mit auswechselbaren Werkzeugen bestückt. Bei äußerst harten Straßenbelägen kann es vorkommen, dass die Werkzeuge lediglich eine Standzeit von einer halben Stunde aufweisen und dass dann alle Werkzeuge der Fräswalze ausgetauscht werden müssen. Hierzu kann das Fahrwerk oder die Fräswalze angehoben werden bis die Fräswalze nicht mehr mit der Bodenoberfläche in Kontakt ist. Eine Bedienungsperson kann nach Wegklappen eines Gehäuseteils des Walzengehäuses den Austausch der Werkzeuge vornehmen. Bei derartigen Baumaschinen mit mechanischem Antrieb muss die Fräswalze zum Auswechseln aller Werkzeuge von Zeit zu Zeit gedreht werden. Dies kann von Hand geschehen, was allerdings sehr hohe Kräfte erfordert. Es ist auch bekannt, die Arbeits- oder Fräswalze mit Hilfe einer Handkurbel zu drehen, wobei die Handkurbel mit einem Untersetzungsgetriebe der Fräswalze gekoppelt wird. Da die Handkurbel nur außen an der Maschine ansetzbar ist, sind letztlich für den Werkzeugwechselvorgang zwei Bedienungspersonen erforderlich.Such large or cold milling machines, or recyclers are used for milling of road surfaces, for example on highways or rural roads. The milling drums are equipped with interchangeable tools on their lateral surface. For extremely hard road surfaces, it may happen that the tools only have a life of half an hour and then that all tools of the milling drum must be replaced. For this purpose, the chassis or the milling drum can be raised until the milling drum is no longer in contact with the soil surface. An operator can make the replacement of the tools after folding away a housing part of the roller housing. In such mechanical-drive construction machinery, the milling drum must be rotated from time to time to replace all the tools. This can be done by hand, but this requires very high forces. It is also known to rotate the working or milling roller by means of a hand crank, wherein the hand crank is coupled to a reduction gear of the milling drum. Since the hand crank can only be attached to the outside of the machine, ultimately two operators are required for the tool changing operation.

Die Drehung der Arbeits- oder Fräswalze mit Hilfe des Antriebsmotors verbietet sich aus Sicherheitsgründen. Außerdem soll die Arbeitswalze nur um einen kleinen Drehwinkel weitergedreht werden, damit die nächste Werkzeugreihe ausgewechselt werden kann.The rotation of the working or milling roller by means of the drive motor is prohibited for safety reasons. In addition, the work roll should only be rotated by a small angle of rotation, so that the next row of tools can be replaced.

Aus der US 4,655,634 ist ein Sicherheitssystem für Straßenbaumaschinen bekannt.From the US 4,655,634 is a safety system for road construction machines known.

Aus der US 4,325,580 ist eine Fräsmaschine bekannt, die einen Hydraulikmotor aufweist, der mit einer Hydraulikpumpe verbunden ist, die Teil der Hauptantriebseinrichtung ist. Ferner ist eine als Hilfsantriebseinheit bezeichnete zweite Hydraulikpumpe als Notdruckquelle vorgesehen, die auch Hilfshydraulikpumpe genannt wird. Die Hilfs-Hydraulikpumpe versorgt ebenfalls den Hydraulikmotor des Fräswalzenantriebs oder die anderen hydraulisch angetriebenen Baugruppen. Die gesamte Baumaschine kann sowohl von der Hydraulikpumpe als auch von der Hilfshydraulikpumpe angetrieben werden, so dass beispielsweise die Hilfsantriebseinheit dazu genutzt werden kann, um die Baumaschine aus der Frässpur zu bewegen. Die Hilfsantriebseinrichtung mit der Hilfshydraulikpumpe versorgt somit die gleichen Antriebsmotoren, sowohl für den Fortbewegungsantrieb als auch für den Fräswalzenantrieb, wie die Hauptantriebseinheit. Einen eigenständigen Hilfsmotor nur für den Antrieb der Fräswalze bei ausgeschaltetem oder entkoppeltem Antriebsmotor weist diese Baumaschine daher nicht auf.From the US 4,325,580 For example, a milling machine is known which has a hydraulic motor connected to a hydraulic pump which is part of the main drive means. Furthermore, a second hydraulic pump, referred to as an auxiliary drive unit, is provided as an emergency pressure source, which is also called an auxiliary hydraulic pump. The auxiliary hydraulic pump also supplies the hydraulic motor of the milling drum drive or the other hydraulically driven assemblies. The entire construction machine can be driven both by the hydraulic pump and by the auxiliary hydraulic pump, so that, for example, the auxiliary drive unit can be used to move the construction machine out of the milling track. The auxiliary drive device with the auxiliary hydraulic pump thus supplies the same drive motors, both for the propulsion drive and for the milling drum drive, such as the main drive unit. An independent auxiliary motor only for driving the milling drum with the drive motor switched off or decoupled, this construction machine therefore does not have.

Der Erfindung liegt die Aufgabe zugrunde, eine Baumaschine der eingangs genannten Art derart zu verbessern, dass ein Auswechseln der Werkzeuge mit einem verringerten Personal- und Zeitbedarf und mit einer verringerten Unfallgefahr ermöglicht wird.The invention has for its object to improve a construction machine of the type mentioned in such a way that a replacement of tools with a reduced staff and time required and with a reduced risk of accidents is possible.

Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1.To solve this problem serve the features of claim 1.

Die Erfindung ermöglicht in vorteilhafter Weise die Reduzierung des Zeitbedarfs für den Werkzeugwechsel, da der Hilfsantrieb von der Bedienungsperson an der Arbeitswalze betätigt werden kann. Da der Hilfsantrieb die Arbeitswalze mit einer geringen Leistung antreibt, ist die Unfallgefahr nahezu ausgeschlossen, die dadurch entsteht, dass sich Bekleidungsteile der Bedienungsperson in den Werkzeugen der Arbeitswalze verfangen können, wenn diese gedreht wird. Da das Drehmoment des Hilfsantriebs gerade genügt, um eine Drehbewegung der Arbeitswalze mit ca. 3 U/min zu ermöglichen, kann der Motor des Hilfsantriebs beim Auftreten höherer Kräfte an der Arbeitswalze schnell gestoppt werden. Außerdem stoppt der Hilfsantrieb nach jeder Inbetriebnahme automatisch nach ca. 4 Sekunden.The invention advantageously makes it possible to reduce the time required for the tool change, since the auxiliary drive can be actuated by the operator on the work roll. Since the auxiliary drive drives the work roll with a low power, the risk of accidents is almost eliminated, which is caused by the fact that clothing parts of the operator can get caught in the tools of the work roll when it is rotated. Since the torque of the auxiliary drive is just sufficient to allow a rotational movement of the work roll at about 3 U / min, the motor of the auxiliary drive can be stopped quickly when higher forces occur on the work roll. In addition, the auxiliary drive automatically stops after approx. 4 seconds after each startup.

Dabei ist vorgesehen, dass das zwischen Arbeitsmotor und Arbeitswalze angeordnete Getriebe aus einem Riemengetriebe mit mindestens zwei Riemenscheiben und mindestens einem Antriebsriemen besteht und dass der Hilfsantrieb mit dem Riemengetriebe koppelbar ist. Bei einem Riemengetriebe lässt sich der Hilfsantrieb in vorteilhafter Weise derart ankoppeln, dass keine Vergrößerung der Breite der Baumaschine erforderlich ist. Der Hilfsantrieb ist innerhalb des Riemenantriebsgehäuses untergebracht, wodurch die Baumaschine nicht verbreitert wird.It is envisaged that the arranged between the engine and work roll gear consists of a belt transmission with at least two pulleys and at least one drive belt and that the auxiliary drive can be coupled to the belt transmission. In a belt transmission can be couple the auxiliary drive in such an advantageous manner that no increase in the width of the construction machine is required. The auxiliary drive is housed within the belt drive housing, whereby the construction machine is not widened.

Es kann vorgesehen sein, dass die motorseitige Riemenscheibe des Riemengetriebes von dem Antriebsmotor über eine Kupplung entkoppelbar ist. Auf diese Weise kann zuverlässig der Kraftfluss zwischen Antriebsmotor und Arbeitswalze unterbrochen werden.It can be provided that the motor-side pulley of the belt drive can be decoupled from the drive motor via a coupling. In this way, the power flow between the drive motor and the work roll can be reliably interrupted.

Bei der bevorzugten Ausführungsform ist vorgesehen, dass der Hilfsantrieb über eine Reibrolle mit dem Riemengetriebe koppelbar ist.In the preferred embodiment, it is provided that the auxiliary drive can be coupled to the belt drive via a friction roller.

Dabei kann die Reibrolle mit der walzenseitigen Riemenscheibe koppelbar sein. Die Verwendung einer Reibrolle hat auch den Vorteil, dass das übertragbare Drehmoment begrenzt ist. Bei einem zu hohen Widerstandsmoment, z.B. bei einer Blockade der Arbeitswalze kann die Reibrolle durchrutschen, wodurch die Unfallgefahr erheblich reduziert wird, da beim Drehen der Arbeitswalze keine hohen Kräfte auftreten können. Dies ist beispielsweise von Bedeutung, wenn sich Kleidungsstücke einer Bedienungsperson an den Werkzeugen der Arbeitswalze während der Drehung der Arbeitswalze verhaken.In this case, the friction roller can be coupled to the roller-side pulley. The use of a friction roller also has the advantage that the transmittable torque is limited. If the moment of resistance is too high, e.g. In a blockade of the work roll, the friction roller can slip, whereby the risk of accidents is significantly reduced because when turning the work roll no high forces can occur. This is important, for example, when garments of an operator get caught on the tools of the work roll during the rotation of the work roll.

Alternativ kann der Hilfsantrieb mit dem mindestens einen Antriebsriemen angekoppelt sein.Alternatively, the auxiliary drive may be coupled to the at least one drive belt.

Nach einer weiteren Alternative kann vorgesehen sein, daß der Hilfsantrieb über ein Zahnrad mit dem Riemengetriebe gekoppelt ist. Beispielsweise kann mindestens ein Antriebsriemen des Riemengetriebes aus einem Zahnriemen bestehen, der mit dem Zahnrad des Hilfsantriebs in Eingriff ist.According to a further alternative it can be provided that the auxiliary drive is coupled via a gear with the belt transmission. For example, at least one drive belt of the belt drive consist of a toothed belt, which is in engagement with the gear of the auxiliary drive.

Bei einem weiteren Ausführungsbeispiel kann die walzenseitige Riemenscheibe ein Zahnrad aufweisen, dass mit dem Zahnrad des Hilfsantriebs im Eingriff ist.In another embodiment, the roller-side pulley may include a gear meshing with the auxiliary drive gear.

Das Riemengetriebe hat vorzugsweise eine Spannrolle, die im gespannten Zustand des mindestens einen Antriebsriemens die walzenseitige Riemenscheibe mit der motorseitigen Riemenscheibe koppelt und im gelösten Zustand die Riemenscheiben voneinander entkoppelt.The belt drive preferably has a tensioning roller which, in the tensioned state of the at least one drive belt, couples the roller-side pulley to the engine-side pulley and, in the released state, decouples the pulleys from one another.

Der Hilfsantrieb kann auch, wenn die motorseitige Riemenscheibe über eine Kupplung entkoppelbar ist, mit einer Spannrolle des Riemengetriebes koppelbar sein. Hierzu kann die Spannrolle zugleich als Reibrolle des Hilfsantriebes auf die Antriebsriemen einwirken, oder die Reibrolle wird zum Antrieb der Spannrolle gegen diese angedrückt.The auxiliary drive can also be coupled with a tension pulley of the belt drive if the engine-side pulley can be decoupled via a clutch. For this purpose, the tension roller can also act as a friction roller of the auxiliary drive on the drive belt, or the friction roller is pressed to drive the tension roller against this.

Vorzugsweise enthält der Hilfsantrieb einen elektrisch betriebenen Motor. Ein derartiger Motor kann von einer Batterie einer Lichtmaschine oder einen Zusatzaggregat mit Strom versorgt werden und kann bei nicht angelegtem Strom im Leerlaufbetrieb mit dem Riemengetriebe permanent gekoppelt sein.Preferably, the auxiliary drive includes an electrically operated motor. Such a motor can be powered by a battery of an alternator or an auxiliary unit and can be permanently coupled to the belt drive when the power is not applied in idling mode.

Alternativ können auch hydraulisch oder pneumatisch betriebene Motoren für den Hilfsantrieb verwendet werden, die mit einer Steuerschaltung auch einen Leerlaufbetrieb ermöglichen.Alternatively, hydraulically or pneumatically operated motors can be used for the auxiliary drive, which also enable an idling operation with a control circuit.

Bei einem besonders bevorzugten Ausführungsbeispiel weist der Hilfsantrieb eine Zeitsteuerung auf, wobei der Hilfsantrieb über eine Fernbedienung gestartet werden kann und die Zeitsteuerung die Einschaltdauer des Motors bestimmt. Bei jedem Start des Hilfsantriebs wird dann die Arbeitswalze um einen fest vorgegebenen, aber variabel einstellbaren Drehwinkel verdreht.In a particularly preferred embodiment, the auxiliary drive on a time control, wherein the auxiliary drive can be started via a remote control and the timing determines the duty cycle of the motor. At each start of the auxiliary drive, the work roll is then rotated by a fixed, but variably adjustable angle of rotation.

Der Motor des Hilfsantriebs ist vorzugsweise nur bei ausgeschaltetem Antriebsmotor für die Arbeitswalze einschaltbar.The motor of the auxiliary drive is preferably switched on only when the drive motor for the work roll off.

Die in Fig. 1 gezeigte Baumaschine 1 ist eine Großfräse mit einem von Fahrschiffen 5 eines höhenverstellbaren Fahrwerks 2.getragenen Maschinenrahmen 4. Der Maschinenrahmen 4 weist eine zwischen den Fahrschiffen 5 angeordnete, an dem Maschinenrahmen 4 gelagerte Arbeitswalze 8 mit aus Fräsmeißeln bestehenden Werkzeugen 14 zum Abarbeiten eines Fahrbahnbelages auf. Die auswechselbaren Werkzeuge 14 sind auf der Mantelfläche 12 der Arbeitswalze 8 in einem vorgegebenen Muster angeordnet. Ein Antriebsstrang 18 treibt die Arbeitswalze 8 an. Zu dem Antriebsstrang 18 gehören zumindest ein Antriebsmotor 6, sowie ein mit dem Antriebsmotor. 6 gekoppeltes Riemengetriebe 16. Das Riemengetriebe 16 besteht aus einer motorseitigen Riemenscheibe 28 und einer walzenseitigen Riemenscheibe 24, die mit mindestens einem Antriebsriemen 30 miteinander gekoppelt sind. Der Antriebsriemen 30 ist vorzugsweise aus Keilriemen zusammengesetzt.In the Fig. 1 The machine frame 4 has an arranged between the vessels 5, mounted on the machine frame 4 work roll 8 with tools consisting of chisels 14 for working a road surface on. The replaceable tools 14 are arranged on the lateral surface 12 of the work roll 8 in a predetermined pattern. A drive train 18 drives the work roll 8 at. The drive train 18 includes at least one drive motor 6, as well as one with the drive motor. The belt transmission 16 consists of a motor-side pulley 28 and a roller-side pulley 24, with at least one drive belt 30th coupled together. The drive belt 30 is preferably composed of V-belts.

Fig. 2 zeigt den Antriebsstrang 18 bestehend aus dem Antriebsmotor 6, der mit einem Pumpenverteilergetriebe 7 gekoppelt sein kann, an dem verschiedene Hydroantriebe für unterschiedliche Funktionen der Baumaschine angeschlossen sein können. Fig. 2 shows the drive train 18 consisting of the drive motor 6, which may be coupled to a pump distributor gearbox 7, to which various hydraulic drives for different functions of the construction machine can be connected.

Der Antriebsmotor 6 bzw. das Pumpenverteilergetriebe 7 kann über eine Kupplung 9 mit der motorseitigen Riemenscheibe 28 gekoppelt sein. Die Arbeitswalze 8 ist in Wänden des Maschinenrahmens 4 gelagert. In der Arbeitswalze 8 kann ein Untersetzungsgetriebe angeordnet sein, das die Drehzahl der walzenseitigen Riemenscheibe 24 beispielsweise im Verhältnis 1:20 untersetzt. Damit kann die Arbeitswalze 8 mit einer Arbeitsdrehzahl von ca. 100 U/min arbeiten, wenn der Verbrennungsmotor mit einer Drehzahl von 2000 U/min betrieben wird und das Riemengetriebe 16 ein Übersetzungsverhältnis von 1:1 hat.The drive motor 6 or the pump distributor 7 may be coupled via a coupling 9 with the motor-side pulley 28. The work roll 8 is mounted in walls of the machine frame 4. In the work roll 8, a reduction gear can be arranged, which reduces the speed of the roller-side pulley 24, for example, in the ratio 1:20. Thus, the work roll 8 can operate at a working speed of about 100 U / min when the engine is operated at a speed of 2000 U / min and the belt transmission 16 has a transmission ratio of 1: 1.

Die auf der Mantelfläche 12 der Arbeitswalze 8 angeordneten auswechselbaren Werkzeuge 14 müssen am Ende ihrer Standzeit durch eine Bedienungsperson gegen neue Werkzeuge ausgewechselt werden, wozu die Bedienungsperson durch Öffnen einer Klappe 11 des Walzengehäuses 13 in den Arbeitsraum hinter der Arbeitswalze 8 eintreten kann. An den in Fahrtrichtung hinteren Fahrschiffen 5 ist jeweils ein Sitz 27 über zwei Gelenkarme 29, 31 an Seitenwänden 15 der Fahrschiffe 5 gelenkig um vertikale Achsen gelagert, so dass die Sitze 27 in einer horizontalen Ebene beliebig verschwenkbar sind.The arranged on the lateral surface 12 of the work roll 8 interchangeable tools 14 must be replaced at the end of their life by an operator against new tools, to which the operator can enter by opening a flap 11 of the roller housing 13 in the working space behind the work roll 8. At the rear in the direction of travel 5 a seat 27 is articulated about two articulated arms 29, 31 on side walls 15 of the vessels 5 about vertical axes, so that the seats 27 are arbitrarily pivotable in a horizontal plane.

Die Bedienungsperson kann von den Sitzen 27 aus eine Fernbedienung 33 für einen Hilfsantrieb 20 bedienen, der mit dem Riemengetriebe 16 koppelbar ist.
Die Arbeitswalze 8. befindet sich dann in einem angehobenen Zustand, so dass die Werkzeuge 14 nicht im Eingriff mit der Bodenoberfläche sind. Mit Hilfe des Hilfsantriebs 20 kann die Arbeitswalze 8 um einen vorbestimmten Drehwinkel derart verdreht werden, dass eine nächste Reihe von Werkzeugen 14 in eine günstige Montageposition gebracht werden können.The operator can operate a remote control 33 for an auxiliary drive 20 from the seats 27, which can be coupled to the belt drive 16.
The work roll 8 is then in a raised condition so that the tools 14 are not engaged with the floor surface. With the aid of the auxiliary drive 20, the work roll 8 can be rotated by a predetermined angle of rotation so that a next series of tools 14 can be brought into a convenient mounting position.

Die Anordnung der Werkzeuge 14 auf der Mantelfläche 12 der Arbeitswalze 8 ist am besten aus Fig. 3 ersichtlich. Bei der Aktivierung des Hilfsantriebs 20 kann die Arbeitswalze 8 um einen bestimmten Winkelbetrag oder für eine bestimmte Zeitdauer gedreht werden.The arrangement of the tools 14 on the lateral surface 12 of the work roll 8 is best Fig. 3 seen. Upon activation of the auxiliary drive 20, the work roll 8 can be rotated by a certain angle or for a certain period of time.

Das Drehmoment des Hilfsantriebs 20 ist höher als das Trägheitsmoment der Arbeitswalze 8 und des Antriebsstrangs 18 bei ausgeschaltetem oder entkoppelten Antriebsmotor 6. Dabei soll das Drehmoment nur um einen solchen Betrag höher sein, dass eine Drehung der Arbeitswalze 8 gewährleistet ist, ohne dass ein Drehmoment auf die Arbeitswalze 8 übertragen wird, das für die Bedienungsperson eine Unfallgefahr darstellt. Beispielsweise genügt es, wenn das übertragene Drehmoment im Bereich von 10 bis 30% höher ist als das Trägheitsmoment der Arbeitswalze 8 und des mitbewegten Teils des Arbeitsstranges 18.The torque of the auxiliary drive 20 is higher than the moment of inertia of the work roll 8 and the drive train 18 with the drive motor 6 switched off or decoupled. In this case, the torque should only be higher by such an amount that a rotation of the work roll 8 is ensured without a torque on the work roll 8 is transmitted, which represents an accident risk for the operator. For example, it is sufficient if the transmitted torque in the range of 10 to 30% higher than the moment of inertia of the work roll 8 and the co-moving part of the work string 18th

Fig. 4 zeigt ein erstes Ausführungsbeispiel eines mit dem Riemengetriebe 16 koppelbaren Hilfsantriebs 20. Wie aus Fig. 4 ersichtlich, läuft der Antriebsriemen 30 über die motorseitige Riemenscheibe 28, über eine von einer Spanneinrichtung 35 andrückbare Spannrolle 38 und über die walzenseitige Riemenscheibe 24 um. An der walzenseitigen Riemenscheibe 4 ist eine Reibrolle 34 des Hilfsantriebs 20 über eine Stelleinrichung 37 andrückbar, wodurch der Hilfsantrieb 20 ein Drehmoment auf die walzenseitige Riemenscheibe 24 übertragen kann. Die Reibrolle 34 hat den Vorteil, dass das übertragbare Drehmoment begrenzt ist. Bei einer Blockade der Arbeitswalze 8 würde die Reibrolle 34 letztlich auf der Riemenscheibe 24 durchrutschen, wodurch eine Unfallgefahr praktisch ausgeschlossen ist. Fig. 4 shows a first embodiment of a couplable with the belt transmission 16 auxiliary drive 20. As out Fig. 4 As can be seen, the drive belt 30 runs over the motor-side pulley 28, via a pressable by a tensioning device 35 tension roller 38 and the roller-side pulley 24. On the roller-side pulley 4 is a friction roller 34 of the auxiliary drive 20 via a Stelleinrichung 37 pressed, whereby the auxiliary drive 20 can transmit torque to the roller-side pulley 24. The friction roller 34 has the advantage that the transmissible torque is limited. In a blockage of the work roll 8, the friction roller 34 would ultimately slip on the pulley 24, whereby an accident risk is virtually eliminated.

Fig. 5 zeigt den Hilfsantrieb 20 in einer entkoppelten Stellung, in der die aus einer Kolbenzylindereinheit bestehende Stelleinrichtung 37 die Reibrolle 34 außer Eingriff gebracht hat. Fig. 5 shows the auxiliary drive 20 in a decoupled position in which the existing of a piston-cylinder unit actuator 37 has brought the friction roller 34 out of engagement.

Fig. 6 zeigt ein weiteres Ausführungsbeispiel, bei dem der Hilfsantrieb 20 anstelle der Reibrolle 34 ein Zahnrad 39 aufweist, dass mit einer Außerverzahnung 41 auf dem Außenumfang der Riemenscheibe 24 im Eingriff ist.Fig. 6 shows a further embodiment in which the auxiliary drive 20 instead of the friction roller 34 has a gear 39 that is with an external gear 41 on the outer circumference of the pulley 24 in engagement.

Der Hilfsantrieb 20 mit Zahnrad 39 kann auch, wie in Fig. 7 gezeigt, direkt mit einem Zahnriemen des Antriebriemens 30 gekoppelt sein, wobei es genügt, dass einer der Riemen mit einer Verzahnung versehen ist. In Fig. 7 ist die Verzahnung des Zahnriemens zur Vereinfachung nur im Bereich des Zahnrades 39 dargestellt.The auxiliary drive 20 with gear 39 may also, as shown in Fig. 7, be coupled directly to a toothed belt of the Antriebriemens 30, wherein it is sufficient that one of the belts is provided with a toothing. In Fig. 7, the toothing of the toothed belt is shown for simplicity only in the range of the gear 39.

Der Motor des Hilfsantriebs 20 der zuvor beschriebenen Ausführungsbeispiele besteht vorzugsweise aus einem Elektromotor, der von einer Lichtmaschine, einer Batterie oder einem Zusatzaggregat mit Strom versorgt werden kann. Der Elektromotor hat den Vorteil, dass ein Leerlaufbetrieb möglich ist, ohne dass der Hilfsantrieb 20 von dem Riemengetriebe 16 entkoppelt werden muss. In diesem Fall kann die Stelleinrichtung 37 entfallen und der Hilfsantrieb 20 permanent mit dem Riemengetriebe 16 gekoppelt sein.The motor of the auxiliary drive 20 of the previously described embodiments preferably consists of an electric motor, which can be powered by an alternator, a battery or an auxiliary unit with power. The electric motor has the advantage that idling operation is possible without the auxiliary drive 20 having to be decoupled from the belt drive 16. In this case, the adjusting device 37 may be omitted and the auxiliary drive 20 may be permanently coupled to the belt transmission 16.

Alternativ kann der Hilfsantrieb auch einen hydraulischen oder pneumatischen Antrieb aufweisen, der allerdings für den Fall, dass der Hilfsantrieb 20 nicht von dem Riemengetriebe 16 entkoppelbar ist, mit einem den Leerlaufbetrieb zulassenden Steuerventil versehen sein muss.Alternatively, the auxiliary drive may also have a hydraulic or pneumatic drive, but in the event that the auxiliary drive 20 is not of the belt transmission 16 can be decoupled, must be provided with an idling operation permitting control valve.

Der Hilfsantrieb 20 weist eine Steuerung auf, die über eine Fernbedienung 33 aktivierbar ist und die Einschaltdauer des Motors steuert. Dabei ist in vorteilhafter Weise vorgesehen, dass bei jeder Aktivierung des Hilfsantriebs durch einen Fernbedienungsschalter die voreingestellte maximale Einschaltdauer und damit eine vorbestimmte maximale Winkeldrehung der Arbeitswalze 14 eingehalten wird.The auxiliary drive 20 has a control which can be activated via a remote control 33 and controls the duty cycle of the motor. It is provided in an advantageous manner that each time the auxiliary drive is activated by a remote control switch the preset maximum duty cycle and thus a predetermined maximum angular rotation of the work roll 14 is maintained.

Wird der Fernbedienungsschalter vor Ablauf der maximalen Einschaltdauer von beispielsweise 4 Sekunden losgelassen, stoppt der Hilfsantrieb 20 vorzeitig.If the remote control switch is released before expiration of the maximum duty cycle of, for example, 4 seconds, the auxiliary drive 20 stops prematurely.

Vorzugsweise weist der Hilfsantrieb 20 eine Sicherheitsschaltung auf, gemäß der der Motor des Hilfsantriebs 20 nur bei ausgeschaltetem Antriebsmotor 6 einschaltbar ist.Preferably, the auxiliary drive 20 has a safety circuit according to which the motor of the auxiliary drive 20 can be switched on only when the drive motor 6 is switched off.

Desweiteren kann eine Sicherheitsschaltung vorgesehen sein, die den Hilfsantrieb 20 beim Überschreiten eines vorgegebenen maximalen Widerstandsmomentes der Arbeitswalze 8 stoppt.
Die Fernbedienung 33 für den Hilfsantrieb befindet sich vorzugsweise an dem Sitz 27 für die Bedienungsperson.Furthermore, a safety circuit may be provided which stops the auxiliary drive 20 when a predetermined maximum resistance moment of the work roll 8 is exceeded.
The remote control 33 for the auxiliary drive is preferably located on the seat 27 for the operator.

Die Fernbedienung 33 kann auch mit einem Magnetfuß versehen sein, wodurch sie beliebig in Reichweite der Bedienungsperson an metallischen Teilen der Baumaschine 1 befestigt werden kann.The remote control 33 may also be provided with a magnetic base, whereby it can be attached as desired within reach of the operator to metallic parts of the construction machine 1.
