Description
Die
Erfindung bezieht sich auf eine elektrische Antriebsvorrichtung
für ein
Flur förderzeug
nach dem Oberbegriff des Patentanspruchs 1 (
Wie bei anderen Fahrzeugen auch wird beim frei fahrenden Flurförderzeug die notwendige Energie in einem Energiespeicher mitgeführt. Bei Flurförderzeugen mit verbrennungsmotorischem Antrieb dient hierzu der Kraftstofftank. Der Nachfüllvorgang läßt sich bekanntermaßen sehr schnell durchführen. Der Energiespeicher für den größten Teil der elektrisch betriebenen Flurförderzeuge ist zur Zeit die Batterie (Akkumulator). Die Energiemenge, die von der Batterie aufgenommen und zur Verfügung gestellt werden kann, ist begrenzt und reicht normalerweise nur für den Einsatz für die Dauer einer Schicht. Bei einem mehrschichtigen Betrieb der Fahrzeuge ist dann nach jeder Schicht ein Austausch der leeren Batterie gegen eine geladene notwendig.As with other vehicles also becomes when free-moving truck carried the necessary energy in an energy storage. at Industrial trucks with internal combustion engine drive serves the fuel tank. The refilling process can be known perform very fast. Of the Energy storage for the biggest part electrically operated industrial trucks is currently the battery (accumulator). The amount of energy used by the Battery can be picked up and provided is limited and usually only for use for the duration a layer. In a multi-shift operation of the vehicles is then After each shift, replace the empty battery with one loaded necessary.
Die Art des Antriebes und damit auch des Energiespeichers bestimmt unter anderem den Einsatzbereich und die Betriebskosten des Fahrzeugs. Verbrennungsmotorisch angetriebene Fahrzeuge sind vom Betriebsaufwand deutlich günstiger, sind jedoch, bedingt durch die Abgasemission, nicht oder nur vorübergehend in geschlossenen Räumen einsetzbar. Hierfür kommen batterieelektrisch angetriebene Fahrzeuge in Frage. Diese Fahrzeuge haben jedoch den Nachteil, daß die Energieauffüllung, d.h. das Laden der Batterie, sehr lange dauert. Sollen die Fahrzeuge über zwei Schichten eingesetzt werden, ist normalerweise eine zweite Batterie erforderlich. Dies führt naturgemäß zu einer erheblichen Erhöhung des Betriebsaufwandes.The Type of drive and thus the energy storage under determined the area of use and the operating costs of the vehicle. Combustion Motorized powered vehicles are significantly cheaper from operating expenses, are, however, due to the exhaust emission, not or only temporarily in closed rooms used. Therefor Battery electric powered vehicles in question. These However, vehicles have the disadvantage that the energy replenishment, i. the Charging the battery, takes a long time. Should the vehicles over two Layers are usually a second battery required. this leads to naturally to one considerable increase the operating expenses.
Aufgrund der beschriebenen Beschränkungen werden häufiger zwei Flurförderzeuge gleichzeitig eingesetzt, nämlich ein verbrennungsmotorisch angetriebenes für den wirtschaftlichen Außeneinsatz und ein batterieelektrisch angetriebenes für den Inneneinsatz. Bei kleinerem Transportaufkommen oder bei bestimmten betrieblichen Abläufen sind die Fahrzeuge unter Umständen nicht ausgelastet, was naturgemäß die Wirtschaftlichkeit verschlechtert.by virtue of the limitations described become more common two industrial trucks used simultaneously, namely an internal combustion engine driven for the economic outdoor use and a battery electric powered for indoor use. At smaller Transport or in certain operational procedures the vehicles under circumstances underutilized, which, of course, the economy deteriorated.
Außerdem sind Verbrennungsmotoren in ihrer Nennleistung so auszulegen, daß das Flurförderzeug seine maximalen Leistungsdaten erreichen kann. Diese Leistungen werden jedoch nur während eines kleinen Anteils der Betriebszeit abgefordert, da das Fahrzeug oft nur teilbeladen oder unbeladen bewegt wird und maximale Fahrgeschwindigkeiten oft aus räumlichen Gründen gar nicht erreicht werden. Diese Umstände reduzieren die Wirtschaftlichkeit derartiger Flurförderzeuge. Verbrennungsmotorisch betriebene Flurförderzeuge haben schließlich den Nachteil, daß beim Bremsen frei werdende Energie nicht rückgewonnen werden kann.Besides, they are In their rated power internal combustion engines designed so that the truck can reach its maximum performance data. These services will be but only during one small portion of the operating time requested as the vehicle often only partially loaded or unloaded is moved and maximum travel speeds often from spatial establish not be reached. These circumstances reduce the profitability of such Material handling equipment. Combustion-powered forklift trucks finally have the disadvantage that at Braking released energy can not be recovered.

Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Antriebsvorrichtung für ein Flurförderzeug zu schaffen, die den Einsatz des Flurförderzeugs sowohl im Innen- als auch im Außenbetrieb ermöglicht und bei dem eine Überdimensionierung verhindert wird.Of the Invention is based on the object, an electric drive device for a Truck to provide the use of the truck in both indoor and outdoor operation allows and in which an oversizing is prevented.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.These The object is solved by the features of claim 1.
Wie an sich bekannt, sieht die Erfindung einen elektrischen Antriebsmotor vor, der von einer Batterie gespeist wird. Zusätzlich ist eine Stromerzeugereinheit vorgesehen, die aus einem Generator und einem den Generator antreibenden Verbrennungsmotor besteht. Der Generator ist vorzugsweise so ausgelegt, daß er als Startermotor betrieben werden kann. Der Generator arbeitet auf das Netz des Flurförderzeugs und damit parallel auch auf die Klemmen der Batterie. Die Stromerzeugereinheit kann mit Hilfe einer Steuer- und Regeleinrichtung automatisch ein- und ausgeschaltet werden.As known per se, the invention provides an electric drive motor which is powered by a battery. In addition, a power generator unit provided, consisting of a generator and a generator driving the Internal combustion engine exists. The generator is preferably designed that he can be operated as a starter motor. The generator works the network of the truck and thus in parallel also on the terminals of the battery. The power generator unit can with the help of a control and regulating device automatically on and turned off.
Dies etwa dann, wenn die Steuer- und Regeleinrichtung den Ladezustand der Batterie überwacht und den Verbrennungsmotor einschaltet, wenn der Ladezustand einen vorgegebenen unteren Wert erreicht. Der Verbrennungsmotor kann automatisch auch wieder ausgeschaltet werden, wenn zum Beispiel ein Vollladezustand der Batterie detektiert wird. Erfindungsgemäß sind beidseits der Längsachse des Flurförderzeugs zur Seite hin offene Aufnahmeräume mit jeweils einer Kontakteinheit vorgesehen, und der Stromerzeuger ist als Modul ausgeführt, das auch einen Kraftstofftank enthält und das entfernbar in einem der Aufnahmeräume des Flurförderzeugs aufnehmbar ist und seinerseits eine Kontakteinheit aufweist, die mit der Kontakteinheit des betreffenden Aufnahmeraums zusammenwirkt. Die Außenabmessungen der Batterie entsprechen denen des Moduls zur Aufnahme im jeweils anderen Aufnahmeraum, wobei eine Kontakteinheit der Batterie mit der Kontakteinheit des betreffenden Aufnahmeraums zusammenwirkt.This for example, when the control and regulating device the state of charge the battery is monitored and the internal combustion engine turns on when the state of charge a predetermined reached lower value. The internal combustion engine can also automatically be switched off again when, for example, a full charge state the battery is detected. According to the invention are on both sides of the longitudinal axis of the truck open-plan recording rooms with each provided a contact unit, and the power generator is executed as a module, which also contains a fuel tank and removable in one the reception rooms of the truck is receivable and in turn has a contact unit, the cooperates with the contact unit of the respective receiving space. The outer dimensions the battery correspond to those of the module for accommodating in each case another receiving space, wherein a contact unit of the battery with the contact unit of the respective receiving space cooperates.
Der Stromerzeuger kann so ausgelegt werden, daß er diejenige Energie bereitstellt, welche während eines üblichen Arbeitseinsatzes des Flurförderzeugs abgefordert wird. Ein externes Nachladen der Batterie kann daher entfallen.Of the Generator may be designed to provide the energy which during a usual one Labor input of the truck is requested.

Beim Betrieb des Flurförderzeugs im gemischten Innen-/Außeneinsatz ist sicherzustellen, daß der Verbrennungsmotor beim Einfahren in geschlossene Räume abgeschaltet wird. Hierfür können die Tore der Gebäude mit entsprechenden Sendeeinheiten ausgerüstet werden, die mit Empfängereinheiten am Flurförderzeug zusammenwirken und den Verbrennungsmotor beim Einfahren in einen geschlossenen Raum automatisch abschalten und beim Herausfahren automatisch den Start freigeben. Je nach Ladezustand wird der Verbrennungsmotor durch die Steuer- und Regeleinrichtung gestartet.At the Operation of the truck in mixed indoor / outdoor use is to make sure that the Internal combustion engine switched off when entering closed rooms becomes. Therefor can the gates of the buildings be equipped with appropriate transmitting units, with receiver units on the truck interact and the internal combustion engine when entering a automatically switch off the closed room and move it out automatically release the start. Depending on the state of charge of the engine is through started the control and regulating device.
Erreicht der Ladezustand der Batterie während des Betriebs in geschlossenen Räumen einen zweiten unteren Grenzwert, wird der Fahrer mit Hilfe einer optischen und/oder akustischen Warneinrichtung auf den Zustand hingewiesen und aufgefordert, die geschlossenen Räume zu verlassen, damit das erneute Laden der Batterie nach Ausfahrt automatisch gestartet werden kann. Je nach Anteil des Inneneinsatzes an der Gesamteinsatzdauer sind die Leistungsfähigkeit des Energiemoduls und die Kapazität der Batterie auszulegen.Reached the state of charge of the battery during Operation in closed rooms a second lower limit, the driver is using a optical and / or audible warning device pointed to the state and asked to leave the closed rooms so that the renewed Charging the battery after exit can be started automatically. Depending on the proportion of indoor use in the total duration of use the efficiency of the power module and the capacity of the battery.
Ist das Verlassen der geschlossenen Räume nicht sinnvoll oder möglich, muß unter Umständen die Neuladung der Batterie oder der Austausch der Batterie durch eine geladene in Kauf genommen werden. Das Energiemodul kann auf diese Weise wahlweise eingesetzt und zum Beispiel durch eine Batterie ersetzt werden, wenn ausschließlich ein Inneneinsatz des Flurförderzeugs vorgesehen ist. Die fahrzeugfeste Kontakteinheit ist mit dem Netz des Fahrzeugs verbunden. Es ist daher vom Fahrzeug aus gesehen gleich, ob ein Stromerzeugermodul oder eine Batterie aufgenommen ist. Das Modul weist vorzugsweise ein Gehäuse auf, das seitlich mit Rollen oder Gleitelementen versehen ist, die mit Schienen oder dergleichen des seitlich offenen Aufnahmeraums zusammenwirken. Das Gehäuse kann nach einer weiteren Ausgestaltung der Erfindung mindestens einen Verriegelungsansatz aufweisen, der mit einer Verriegelungsvorrichtung im Aufnahmeraum zusammenwirkt zur automatischen Verriegelung des Moduls bei vollständiger Aufnahme im Aufnahmeraum. Die Verriegelungsvorrichtung kann nach einer weiteren Ausgestaltung der Erfindung so ausgebildet sein, daß sie mit Hilfe einer Transportvorrichtung für das Modul oder die Batterie entriegelbar ist.is the leaving of the closed rooms not meaningful or possible, must under Circumstances the Recharge the battery or replace the battery with a charged one be accepted. The power module can in this way optionally used and replaced for example by a battery, if only an interior insert of the truck is provided. The vehicle-fixed contact unit is connected to the network connected to the vehicle. It is therefore the same from the vehicle, whether a generator module or a battery is included. The Module preferably has a housing on, which is provided laterally with rollers or sliding elements, the with rails or the like of the laterally open receiving space interact. The housing can according to a further embodiment of the invention, at least a locking lug, which with a locking device in the receiving space cooperates for automatic locking of the Module at more complete Recording in the recording room. The locking device can after a further embodiment of the invention be designed so that she is with Help a transport device for the module or the battery is unlockable.
Da bei der Erfindung sowohl für den Fahrantrieb als auch für z. B. den Hubantrieb ein Elektromotor vorgesehen werden kann, kann dieser auch als Generator betrieben werden. Somit besteht auch bei der Erfindung die Möglichkeit, eine Energierückgewinnung beim Bremsen oder beim Senken einer Last vorzusehen. Außerdem kann eine elektromotorische Bremsung vorgesehen werden. Energierückgewinnung und elektrisches Bremsen ist an sich bekannt.There in the invention both for the drive as well as for z. B. the lifting drive an electric motor can be provided can This can also be operated as a generator. Thus exists also with the Invention the possibility an energy recovery when braking or when lowering a load. In addition, can an electromotive braking are provided. Energy recovery and electric braking is known per se.
Der Stromerzeuger nach der Erfindung kann vollständig gekapselt werden und dadurch eine minimale Schallemission verursachen. Er kann schwingungstechnisch vom übrigen Flurförderzeug entkoppelt sein. Eine spezielle Starterbatterie für den Startermotor des Verbrennungsmotors entfällt. Es kann auch ein Ladegerät entfallen und gegebenenfalls auch eine Wechselbatterie bei gemischtem Innen-/Außeneinsatz.Of the Power generator according to the invention can be completely encapsulated and thereby cause a minimum noise emission. He can vibrationally from the rest Truck be decoupled. A special starter battery for the starter motor the internal combustion engine is eliminated. It can also be a charger omitted and possibly also a replaceable battery with mixed Indoor / outdoor use.
