BodenverdichtungsvorrichtungSoil compacting device
Die Erfindung betrifft eine Bodenverdichtungsvorrichtung gemäß dem Oberbegriff von Anspruch 1 .The invention relates to a soil compacting device according to the preamble of claim 1.
Derartige Bodenverdichtungsvorrichtungen sind bekannt und werden auch als Stampfer bzw. Vibrationsstampfer bezeichnet.Such soil compacting devices are known and are also referred to as rammers or vibration tampers.
Es ist bekannt, bei derartigen Stampfern entweder einen Verbrennungsmotor, beispielsweise einen Benzin- oder einen Dieselmotor, oder alternativ einen Elektroan- trieb vorzusehen. Verbrennungsmotoren haben den Vorteil, von externen Energiequellen unabhängig zu sein. Nachteilig hingegen ist es, dass die Verbrennungsmotoren Abgase und Lärm emittieren. Das Problem der Lärm- oder Schadstoffemissi- onen besteht hingegen bei Elektroantrieben nicht. Dort ist jedoch erforderlich, ein Stromnetz oder einen Generator zur Verfügung zu stellen, um den Elektromotor betreiben zu können. Zudem ist ein Netzkabel erforderlich, um den Stampfer mit der Stromquelle (Netzanschluss) verbinden zu können. Dies beeinträchtigt die Handhabbarkeit von Elektrostampfern.It is known in such rammers to provide either an internal combustion engine, for example a gasoline engine or a diesel engine, or alternatively an electric drive. Internal combustion engines have the advantage of being independent of external energy sources. A disadvantage, however, is that the internal combustion engines emit exhaust gases and noise. The problem of noise or pollutant emissions, on the other hand, does not exist with electric drives. There, however, it is necessary to provide a power grid or a generator to operate the electric motor can. In addition, a power cord is required to connect the rammer with the power source (power supply) can. This affects the manageability of electric rammers.
Fig. 1 zeigt in schematischer Seitenansicht einen an sich bekannten Stampfer in Seitenansicht.Fig. 1 shows a schematic side view of a known tamper in side view.
Im oberen Bereich ist ein Verbrennungsmotor 1 zwischen einem Führungsbügel 2 angeordnet. Der Verbrennungsmotor 1 erhält Kraftstoff aus einem Tank 3, der an dem Führungsbügel 2 angebracht ist. Mit Hilfe des Führungsbügels 2 kann ein Bediener den Stampfer in an sich bekannter Weise führen. Unterhalb von dem Verbrennungsmotor 1 ist ein Gehäuse 4 vorgesehen, in dem eine Bewegungswandeleinrichtung zum Wandeln einer Drehbewegung des Verbrennungsmotors 1 in eine oszillierende Linearbewegung eines Bodenkontaktelements 6 angeordnet ist. Die Bewegungswandeleinrichtung 5 wird später noch anhand von Fig. 2 näher erläutert. Das Bodenkontaktelement 6 ist als Stampffuß ausgebildet.In the upper area, an internal combustion engine 1 is arranged between a guide bracket 2. The internal combustion engine 1 receives fuel from a tank 3 which is attached to the guide bracket 2. With the help of the guide bracket 2, an operator can lead the rammer in a conventional manner. Below the internal combustion engine 1, a housing 4 is provided, in which a motion conversion device for converting a rotational movement of the internal combustion engine 1 is arranged in an oscillating linear movement of a ground contact element 6. The movement conversion device 5 will be explained later with reference to FIG. 2. The ground contact element 6 is designed as a padfoot.
Fig. 2 zeigt einen Schnitt durch das Gehäuse 4.2 shows a section through the housing 4.
Von dem Verbrennungsmotor 1 erstreckt sich eine senkrecht nach unten ragende Motorwelle 7. Auf dem konischen Wellenende der Motorwelle 7 ist eine eine Kupp- lungseinrichtung bildende Fliehkraftkupplung 8 aufgesetzt. Die Fliehkraftkupplung 8 ist in an sich bekannter Weise ausgebildet und weist mehrere Fliehkraftelemente 9 auf, die durch Federn 10 in einer radial innen liegenden Ausgangsstellung gehalten werden. Sobald die Drehzahl der Motorwelle 7 einen vorgegebenen Wert überschreitet, bewegen sich die Fliehkraftelemente 9 gegen die Wirkung der Federn 10 nach außen und stellen so einen Form- bzw. Kraftschluss zwischen einem innen liegenden Antriebsufer 1 1 der Fliehkraftkupplung und einem außen liegenden Abtriebsufer 12 her. Das Abtriebsufer 12 wird durch eine Kupplungsglocke 13 gebildet.Of the internal combustion engine 1 extends a vertically downwardly projecting motor shaft 7. On the conical shaft end of the motor shaft 7 is a a Kupp- lungseinrichtung forming centrifugal clutch 8 attached. The centrifugal clutch 8 is formed in a conventional manner and has a plurality of centrifugal elements 9, which are held by springs 10 in a radially inner starting position. Once the speed of the motor shaft 7 exceeds a predetermined value, the centrifugal elements 9 move against the action of the springs 10 to the outside and thus provide a positive or frictional connection between an inner drive shaft 1 1 of the centrifugal clutch and an external output shaft 12 ago. The output bank 12 is formed by a clutch bell 13.
Die Kupplungsglocke 13 ist Teil einer Zwischenwelle 14, deren Drehbewegung ü- ber eine Kegelradverzahnung auf eine Kurbelscheibe 15 übertragen wird.The clutch bell 13 is part of an intermediate shaft 14 whose rotational movement is transferred via a bevel gear toothing to a crank disk 15.
Auf der Kurbelscheibe 15 ist ein Kurbelzapfen 16 vorgesehen, der in bekannter Weise ein Pleuel 17 antreibt. Das Pleuel 17 ist über einen nicht dargestellten Zwischenkolben und Federpakete mit dem Bodenkontaktelement 6 gekoppelt. Auf diese Weise kann die Bewegung des Pleuels 17 in die oszillierende Linearbewegung des Bodenkontaktelements 6 gewandelt werden.On the crank disc 15, a crank pin 16 is provided which drives a connecting rod 17 in a known manner. The connecting rod 17 is coupled via an unillustrated intermediate piston and spring assemblies with the ground contact element 6. In this way, the movement of the connecting rod 17 can be converted into the oscillating linear movement of the ground contact element 6.
Der Aufbau eines derartigen Stampfers und insbesondere der Bewegungswandeleinrichtung 5 ist an sich bekannt und muss daher an dieser Stelle nicht näher vertieft werden.The structure of such a rammer and in particular of the movement-changing device 5 is known per se and therefore does not need to be recessed further at this point.
Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Bodenverdichtungs- Vorrichtung anzugeben, die bezüglich der Einsatzmöglichkeiten und der Handhabbarkeit den bislang bekannten Vorrichtungen überlegen ist.The invention has for its object to provide an improved soil compacting device, which is superior to the previously known devices in terms of applications and manageability.
Die Aufgabe wird erfindungsgemäß durch eine Bodenverdichtungsvorrichtung nach Anspruch 1 gelöst. Weiterentwicklungen sind in den abhängigen Ansprüchen angegeben.The object is achieved by a soil compacting device according to claim 1. Further developments are specified in the dependent claims.
Eine Bodenverdichtungsvorrichtung weist einen Verbrennungsmotor, ein Bodenkontaktelement, eine Bewegungswandeleinrichtung zum Wandeln einer Drehbewegung des Verbrennungsmotors in eine oszillierende Linearbewegung des Boden- kontaktelements sowie eine Kupplungseinrichtung zum Verbinden und Unterbrechen des Kraftflusses zwischen dem Verbrennungsmotor und der Bewegungswandeleinrichtung auf. Diese Bodenverdichtungsvorrichtung ist dadurch gekennzeichnet, dass zusätzlich zu dem Verbrennungsmotor ein Elektromotor mit einem Rotor und einem Stator vorgesehen ist, und dass die Bewegungswandeleinrich- tung wahlweise durch den Verbrennungsmotor oder durch den Elektromotor antreibbar ist.A soil compaction device comprises an internal combustion engine, a ground contact element, a movement conversion device for converting a rotational movement of the internal combustion engine into an oscillating linear movement of the bottom contact element, and a clutch device for connecting and interrupting the flow of force between the internal combustion engine and the movement conversion device. This soil compaction device is characterized in that in addition to the internal combustion engine, an electric motor with a rotor and a stator is provided, and that the movement conversion device tion either by the internal combustion engine or by the electric motor is driven.
Ein Teil der Bodenverdichtungsvorrichtung entspricht somit einer klassischen Bodenverdichtungsvorrichtung mit Verbrennungsmotor, bei der ein Bodenkontaktelement, z .B. ein Stampffuß , durch den Verbrennungsmotor über die Bewegungswandeleinrichtung, z.B. einen Kurbeltrieb, angetrieben wird, um eine Stampfbewegung durchzuführen. Zusätzlich ist die Kupplungseinrichtung vorgesehen, mit der der Kraftfluss zwischen dem Verbrennungsmotor und der Bewe- gungswandeleinrichtung je nach Bedarf unterbrochen oder verbunden werden kann. Die Kupplungseinrichtung kann z.B. eine Fliehkraftkupplung aufweisen, die in Abhängigkeit von der Drehzahl der antreibenden Welle (z. B. Motorwelle) den Kraftfluss weiterführt oder unterbricht. So ist es möglich, dass der Stampfbetrieb unterbrochen wird, wenn der Verbrennungsmotor mit niedriger, unterhalb eines vorgegebenen Grenzwerts liegender Drehzahl, z.B. Leerlaufdrehzahl, dreht. Erst bei einem Erhöhen der Drehzahl des Verbrennungsmotors über den vorbestimmten Wert schließt die Kupplungseinrichtung den Kraftfluss, so dass das Bodenkontaktelement angetrieben wird. Bei Verminderung der Drehzahl unter den vorgegebenen Drehzahlwert kommt der Stampfer wieder zum Stillstand, obwohl der Verbrennungsmotor z.B . mit Leerlaufdrehzahl weiter betrieben werden kann.A part of the soil compacting device thus corresponds to a conventional soil compacting device with internal combustion engine, in which a ground contact element, eg. a padfoot, by the engine via the motion converter, e.g. a crank mechanism is driven to perform a pitching movement. In addition, the coupling device is provided, with which the power flow between the internal combustion engine and the movement conversion device can be interrupted or connected as required. The coupling device may e.g. have a centrifugal clutch, which continues or interrupts the power flow as a function of the rotational speed of the driving shaft (eg motor shaft). Thus, it is possible that the ramming operation is interrupted when the internal combustion engine with low, below a predetermined limit lying speed, e.g. Idling speed, turns. Only when increasing the speed of the internal combustion engine above the predetermined value, the coupling device closes the power flow, so that the ground contact element is driven. When reducing the speed below the predetermined speed value of the rammer comes to a standstill, although the engine z. can continue to operate at idle speed.
Zusätzlich zu dem Verbrennungsmotor ist der Elektromotor vorgesehen, wobei z.B. mit Hilfe der Umschalteinrichtung zwischen dem Verbrennungsmotor und dem Elektromotor hin- und hergeschaltet werden kann. Der Bediener kann somit je nach Anwendungsfall und zur Verfügung stehender Energie wählen, ob die Bodenverdichtungsvorrichtung von dem Verbrennungsmotor oder von dem Elektromotor angetrieben werden soll. Somit ist je nach Wunsch des Bedieners ein autarker Betrieb, fernab von irgendwelchen Netzanschlüssen mit Hilfe des Verbrennungsmotors oder ein umweltfreundlicher, emissionsarmer Betrieb mit Hilfe des Elektromotors möglich.In addition to the internal combustion engine, the electric motor is provided, e.g. can be switched back and forth with the help of the switching device between the engine and the electric motor. Depending on the application and available energy, the operator can thus choose whether the soil compacting device is to be driven by the internal combustion engine or by the electric motor. Thus, depending on the request of the operator, a self-sufficient operation, far away from any power connections with the help of the internal combustion engine or an environmentally friendly, low-emission operation using the electric motor possible.
Die Umschalteinrichtung kann z .B. dadurch automatisiert werden, dass der E- lektromotor automatisch ausgewählt wird, wenn ein Netzkabel an der Bodenverdichtungsvorrichtung angeschlossen ist.The switching device can, for. be automated, that the electric motor is automatically selected when a power cord is connected to the soil compacting device.
Der Elektromotor kann über ein Netzkabel an ein Stromnetz anschließbar sein. Zusätzlich oder alternativ kann an der Bodenverdichtungsvorrichtung ein elektrischer Energiespeicher, z . B. eine Batterie bzw. ein Akku , vorgesehen sein, mit dessen Hilfe der Elektromotor - ähnlich einem Laptop - speisbar ist. Der Energiespei- eher kann über das Netzkabel aufgeladen werden. Bei einer Variante kann der Energiespeicher auch durch den dann generatorisch betriebenen Elektromotor aufgeladen werden, wobei dieser wiederum durch den Verbrennungsmotor angetrieben wird.The electric motor can be connected via a mains cable to a power grid. Additionally or alternatively, an electrical energy storage, for. As a battery or a battery, be provided, with the help of the electric motor - like a laptop - can be fed. The energy supply rather, can be charged via the power cord. In a variant of the energy storage can also be charged by the then operated as a generator electric motor, which in turn is driven by the engine.
Ebenso ist es auch möglich, dass beide Antriebsmotoren, also sowohl der Verbrennungsmotor als auch der Elektromotor parallel zueinander betrieben werden, um auf diese Weise etwa die doppelte Antriebsleistung zur Verfügung zu stellen. Da aber im Regelfall jeder der Motoren für sich genommen ausreichend di- mensioniert sein dürfte, wird dieser Anwendungsfall eher von untergeordneter Bedeutung sein. Dementsprechend kann die Umschalteinrichtung derart ausgestaltet sein, dass z.B. ein Betreiben des Elektromotors dann nicht möglich ist, wenn der Verbrennungsmotor in Betrieb ist.Likewise, it is also possible that both drive motors, so both the engine and the electric motor are operated in parallel to each other in order to provide about twice the drive power in this way. Since, as a rule, each of the motors per se should be sufficiently dimensioned, this application will be of secondary importance. Accordingly, the switching means may be configured such that e.g. operating the electric motor is not possible when the internal combustion engine is in operation.
Die Kupplungseinrichtung kann ein mit dem Verbrennungsmotor gekoppeltes Antriebsufer, ein mit der Bewegungswandeleinrichtung gekoppeltes Abtriebsufer sowie wenigstens ein zwischen dem Antriebsufer und dem Abtriebsufer wirkendes Kupplungselement aufweisen, wobei der Rotor des Elektromotors mit dem Abtriebsufer der Kupplungseinrichtung gekoppelt ist. Auf diese Weise ist es sehr ein- fach möglich, den Elektromotor in den bzw. nahe an dem Kraftfluss zwischen Verbrennungsmotor und Bewegungswandeleinrichtung anzuordnen, um den baulichen Aufwand für die zusätzliche Integration des Elektromotors gering zu halten. Wahlweise kann der Verbrennungsmotor das Abtriebsufer über die Kupplungseinrichtung antreiben oder der Elektromotor seinerseits über seinem Rotor das Ab- triebsufer beaufschlagen.The coupling device can have a drive bank coupled to the internal combustion engine, a driven bank coupled to the motion converter and at least one coupling element acting between the drive bank and the output bank, the rotor of the electric motor being coupled to the output bank of the coupling device. In this way, it is very easily possible to arrange the electric motor in or close to the power flow between the internal combustion engine and the motion converter in order to keep the construction costs for the additional integration of the electric motor low. Optionally, the internal combustion engine can drive the output bank via the clutch device or the electric motor in turn can act on its output via its rotor.
Das Abtriebsufer der Kupplungseinrichtung gibt dann die Antriebsenergie an die Bewegungswandeleinrichtung weiter, um das Bodenkontaktelement in der gewünschten Weise zu bewegen.The output bank of the clutch device then forwards the drive energy to the motion converter in order to move the ground contact element in the desired manner.
Der Rotor kann mit dem Abtriebsufer der Kupplungseinrichtung eine bauliche Einheit bilden. Auf diese Weise kann der Rotor direkt auf dem Abtriebsufer vorgesehen sein. Ebenso kann das Abtriebsufer seinerseits den Rotor des Elektromotors bilden.The rotor can form a structural unit with the output bank of the coupling device. In this way, the rotor can be provided directly on the output bank. Likewise, the output bank in turn can form the rotor of the electric motor.
Bei einer Variante ist an dem Abtriebsufer der Kupplungseinrichtung eine Verzahnung ausgebildet, wobei der Rotor des Elektromotors mit einem Ritzel gekoppelt ist, das mit der Verzahnung des Abtriebsufers kämmt. Bei dieser Alternative kann z.B. eine das Abtriebsufer der Kupplungseinrichtung bildende Fliehkraft- kupplungsglocke mit einer Außenverzahnung ausgeführt werden, in die das Ritzel des dann separat vorgesehenen Elektromotors eingreift. Diese Lösung ermöglicht es, dass der Motor mit deutlich höherer Drehzahl betrieben werden kann, was zu einer kleineren Baugröße und einem besseren Wirkungsgrad führt. Allerdings ist ein zusätzlicher Aufwand für die eigene Lagerung der Motorwelle und die Verzahnung zu betreiben.In one variant, a toothing is formed on the output shaft of the coupling device, wherein the rotor of the electric motor is coupled to a pinion, which meshes with the toothing of the output shaft. In this alternative, for example, a centrifugal force forming the output bank of the coupling device can be used. Clutch bell be performed with an external toothing, in which engages the pinion of the then separately provided electric motor. This solution allows the motor to operate at a significantly higher speed, resulting in a smaller size and better efficiency. However, an additional expense for the own storage of the motor shaft and the teeth to operate.
Die Kupplungseinrichtung kann eine Fliehkraft-Kupplungseinrichtung sein, zum Verbinden und Unterbrechen des Kraftflusses zwischen dem Verbrennungsmotor und der Bewegungswandeleinrichtung in Abhängigkeit von einer Drehzahl des Verbrennungsmotors. Dies wurde oben bereits erläutert.The coupling device may be a centrifugal clutch device, for connecting and interrupting the power flow between the internal combustion engine and the motion conversion device in dependence on a rotational speed of the internal combustion engine. This has already been explained above.
Dabei ist es möglich, dass das Kupplungselement ein Fliehkraftelement ist. Bei Fliehkraft-Kupplungseinrichtungen ist es üblich, dass ein oder mehrere Flieh- kraftelemente in Abhängigkeit von der Antriebsdrehzahl sich bei Überschreiten einer vorgegebenen Grenzdrehzahl gegen die Wirkung einer Feder oder anderer zurückhaltender Kräfte radial nach außen bewegen und dadurch eine kraftschlüssige oder formschlüssige Verbindung zwischen dem Antriebsufer und dem Abtriebsufer der Kupplung herstellen. Fliehkraftkupplungen sind an sich bekannt, so dass an dieser Stelle keine weitere Erläuterung erforderlich ist.It is possible that the coupling element is a centrifugal element. In centrifugal clutch devices, it is customary for one or more centrifugal force elements to move radially outward as a function of the drive rotational speed when a predefined limit rotational speed is exceeded, against the action of a spring or other restraining forces, thereby achieving a non-positive or positive connection between the drive bank and make the output bank of the clutch. Centrifugal clutches are known per se, so that no further explanation is required at this point.
Das Antriebsufer kann mit einer Motorwelle des Verbrennungsmotors gekoppelt sein. So ist es z.B. möglich, dass die Kupplungseinrichtung direkt auf der Motorwelle aufgesetzt ist, um zusätzliche Bauelemente oder Kupplungseinrichtungen zu vermeiden.The drive bank may be coupled to a motor shaft of the internal combustion engine. So it is e.g. possible that the coupling device is placed directly on the motor shaft to avoid additional components or coupling devices.
Das Abtriebsufer kann als Kupplungsglocke ausgebildet sein, wobei der Rotor am Außenumfang der Kupplungsglocke ausgebildet sein kann. Fliehkraftkupplungen weisen häufig eine derartige Kupplungsglocke auf, die glockenartig das Fliehkraft- element bzw. die mehreren Fliehkraftelemente und das Antriebsufer umgibt. Die Kupplungsglocke stellt ihrerseits dann das Abtriebsufer dar. Da die Kupplungsglocke meist rotationssymmetrisch ist, ist es in besonders einfacher Weise möglich, den Rotor des Elektromotors an der Außenseite der Kupplungsglocke aufzusetzen, an der Außenseite der Kupplungsglocke auszubilden oder in die Kupp- lungsglocke zu integrieren.The output bank may be formed as a clutch bell, wherein the rotor may be formed on the outer circumference of the clutch bell. Centrifugal clutches often have such a clutch bell which surrounds the centrifugal force element or the plurality of centrifugal force elements and the drive bank in the manner of a bell. Since the clutch bell is usually rotationally symmetrical, it is possible in a particularly simple manner to place the rotor of the electric motor on the outside of the clutch bell, to form it on the outside of the clutch bell or to integrate it into the clutch bell.
Entsprechend kann der Stator in einem die Kupplungseinrichtung umgebenden Gehäuse vorgesehen sein. Auf diese Weise ist es nicht erforderlich, für den Elektromotor ein eigenes Gehäuse bereitzustellen, was den baulichen Aufwand und das Gewicht der Vorrichtung vergrößern würde. Vielmehr ist es möglich , den Stator direkt in das ohnehin vorhandene, die Kupplungseinrichtung umgebende Gehäuse zu integrieren.Accordingly, the stator may be provided in a housing surrounding the coupling device. In this way, it is not necessary to provide a separate housing for the electric motor, which reduces the construction costs and would increase the weight of the device. Rather, it is possible to integrate the stator directly into the already existing, surrounding the coupling device housing.
Bei einer anderen Ausführungsform kann die Bewegungswandeleinrichtung eine Verzahnung aufweisen und der Elektromotor ein Ritzel aufweisen, das mit der Verzahnung der Bewegungswandeleinrichtung kämmt. So ist es z .B. möglich, dass der Elektromotor ein Kegelradritzel antreibt, das in die Verzahnung eines zu der Bewegungswandeleinrichtung gehörenden Kegelrades des Kurbeltriebes eingreift.In another embodiment, the movement conversion device may have a toothing and the electric motor may have a pinion that meshes with the toothing of the movement conversion device. So it is for example. possible that the electric motor drives a Kegelradritzel which engages in the toothing of a belonging to the motion converter bevel gear of the crank mechanism.
Die Bodenverdichtungsvorrichtung kann ein Stampfer zur Bodenverdichtung sein, wobei die Bewegungswandeleinrichtung einen Kurbeltrieb aufweist und das Bodenkontaktelement ein Stampffuß ist.The soil compaction device may be a rammer for soil compaction, wherein the movement conversion device has a crank drive and the soil contact element is a padfoot.
Diese und weitere Vorteile und Merkmale werden nachfolgend anhand eines Beispiels unter Zuhilfenahme der begleitenden Figuren näher erläutert. Es zeigen:These and other advantages and features will be explained in more detail below by way of example with the aid of the accompanying figures. Show it:
Fig. 1 einen bekannten Stampfer als Bodenverdichtungsvorrichtung in Seitenansicht;Figure 1 shows a known rammer as Bodenverdichtungsvorrichtung in side view.
Fig. 2 einen Teilschnitt des bekannten Stampfers von Fig. 1 ;Fig. 2 is a partial section of the known rammer of Fig. 1;
Fig. 3 einen Stampfer als erfindungsgemäße Bodenverdichtungsvorrichtung in Seitenansicht; undFIG. 3 shows a rammer as a soil compaction device according to the invention in side view; FIG. and
Fig. 4 eine Teilschnittdarstellung des Stampfers von Fig. 3.4 is a partial sectional view of the rammer of FIG. 3.
Fig. 3 zeigt eine erfindungsgemäße Ausgestaltung des an sich bekannten, anhand von Fig. 1 und 2 beschriebenen Bodenverdichtungsstampfers. Demgemäß wird auf die obige Beschreibung zu den Fig. 1 und 2 Bezug genommen. Gleiche Bauelemente werden - soweit möglich - nicht nochmals im Einzelnen beschrieben. Lediglich die Unterschiede zu dem aus dem Stand der Technik bekannten Stampfer werden nachfolgend erläutert.Fig. 3 shows an inventive embodiment of the known per se, with reference to FIGS. 1 and 2 described Bodenverdichtungsstampfers. Accordingly, reference is made to the above description to Figs. 1 and 2. The same components are - as far as possible - not described in detail again. Only the differences from the known from the prior art rammer are explained below.
Während der anhand von Fig. 1 beschriebene Stampfer lediglich den Verbrennungsmotor 1 als Antrieb aufweist, ist bei dem in Fig. 3 gezeigten Stampfer zusätzlich ein Elektromotor 20 vorgesehen. Je nach Wunsch des Bedieners bzw. je nach Möglichkeit kann zwischen einem Antrieb durch den Verbrennungsmotor 1 oder durch den Elektromotor 20 hin- und hergewechselt werden. Wenn z .B. ein Netzanschluss in der Nähe des Arbeitsorts zur Verfügung steht, kann der emissionsarme Elektromotor 20 betrieben werden, während der Verbrennungsmotor 1 abgeschaltet ist. Im freien Gelände hingegen, wo in der Regel kein elektrisches Netz zur Verfügung steht, wird der Stampfer durch den Verbrennungsmotor 1 an- getrieben, während der Elektromotor 20 funktionslos ist.While the rammer described with reference to FIG. 1 only has the internal combustion engine 1 as the drive, an electric motor 20 is additionally provided in the rammer shown in FIG. 3. Depending on the wishes of the operator or depending on the possibility can be switched back and forth between a drive by the internal combustion engine 1 or by the electric motor 20. If, for example, one Power supply is available near the workplace, the low-emission electric motor 20 can be operated while the internal combustion engine 1 is turned off. In open terrain, however, where usually no electrical network is available, the rammer is driven by the internal combustion engine 1, while the electric motor 20 is inoperative.
Fig. 4 zeigt einen Schnitt durch das Gehäuse 4, vergleichbar zu dem Schnitt gemäß Fig. 2.4 shows a section through the housing 4, comparable to the section according to FIG. 2.
Dabei ist erkennbar, dass der Elektromotor 20 im Bereich der Fliehkraftkupplung 8 angeordnet ist.It can be seen that the electric motor 20 is arranged in the region of the centrifugal clutch 8.
Zu diesem Zweck ist auf dem Außenumfang der Kupplungsglocke 13 ein Rotor 21 des Elektromotors 20 angeordnet. Am Umfang gegenüberliegend ist in dem Ge- häuse 4 ein Stator 22 des Elektromotors 20 eingesetzt.For this purpose, a rotor 21 of the electric motor 20 is arranged on the outer circumference of the clutch bell 13. Opposite the circumference, a stator 22 of the electric motor 20 is inserted in the housing 4.
Der Rotor 21 kann z.B. durch Magnete gebildet werden, die durch entsprechende Ansteuerung der Spulen des Stators 22 in Drehung versetzt werden.The rotor 21 may be e.g. are formed by magnets which are rotated by appropriate control of the coils of the stator 22 in rotation.
Da der Rotor 21 direkt auf der das Abtriebsufer 12 bildenden Kupplungsglocke 13 angeordnet ist, wird die von dem Elektromotor 20 erzeugte Drehbewegung problemlos und in gleicher Weise wie bei dem Verbrennungsmotor 1 über die Bewegungswandeleinrichtung 5, insbesondere über die Kurbelscheibe 15 und das Pleuel 17 auf den Stampffuß 6 übertragen.Since the rotor 21 is arranged directly on the output shaft 12 forming the clutch bell 13, the rotational movement generated by the electric motor 20 is easily and in the same manner as in the internal combustion engine 1 via the motion conversion device 5, in particular via the crank pulley 15 and the connecting rod 17 on the Transfer padfoot 6.
Die Fliehkraftkupplung 8 stellt dabei sicher, dass der Elektromotor 20 nicht zusätzlich auch noch die Motorwelle 7 des Verbrennungsmotors mit antreiben muss.The centrifugal clutch 8 ensures that the electric motor 20 does not have to additionally drive the motor shaft 7 of the internal combustion engine.
Dadurch, dass der Elektromotor 20 direkt an die Fliehkraftkupplung 8 einerseits und in das Gehäuse 4 andererseits integriert ist, kann der Elektromotor 20 bei minimaler Modifikation des an sich bekannten Stampfers eingebaut werden. Characterized in that the electric motor 20 is integrated directly to the centrifugal clutch 8 on the one hand and in the housing 4 on the other hand, the electric motor 20 can be installed with minimal modification of the known ramper.
