Description

Fahrzeug mit batterie-elektrischem Antrieb Vehicle with battery-electric drive

Die Erfindung betrifft ein Fahrzeug, insbesondere ein Nutzlastfahrzeug wie einen Plattformwagen oder einen Industriewerkschlepper oder einen Hublader mit batterieelektrischem Antrieb, bei dem die Batterie zwischen den Achsen angeordnet ist.The invention relates to a vehicle, in particular a utility vehicle like a platform truck or an industrial tractor or a lift truck battery-electric drive in which the battery is arranged between the axles is.

Heute besteht oft die Aufgabe, mit derartigen Nutzlastfahrzeugen einerseits in bestimmten Betriebsphasen in geschlossenen Räumen oder sonstigen Räumen,in denen keine Abgase zulässig sind, zu fahren und in anderen Betriebsphasen im Freien oder sonstigen Räumen, in denen Abgase zulässig sind, so große Strecken mit so großer Geschwindigkeit oder so großer Zuglast zu fahren, daß ein Fahren dieser Strecken mit Batteriestrom mit Rücksicht auf die Ladungskapazität der Batterie und deren nur beschränkte Wiederaufladbarkeit unwirtschaftlich wäre. Es ist bekannt, zu diesem Zweck Fahrzeuge zu verwenden, die außer mit der Batterie mit einem Dieselgeneratoraggregat ausgerüstet sind, welches für die Fahrt im Freien in Betrieb gesetzt wird und die Fahrelektromotoren über den Generator speist. Bei den bisher bekannten Fahrzeugen dieser Art ist bei der Fahrzeugkon- struktion ausgegangen worden von der Bauform eines Fahrzeuges mit rein batterie-elektrischem Antrieb, bei dem die Batterie in einem nach oben offenen Raum angeordnet ist und nach oben herausgehoben und eingesetzt werden kann und ist in diesem Raum eine kleinere Batterie eingesetzt als im Normalzustand und ist in den freibleibenden Batterieraum das Dieselgeneratoraggregat eingesetzt. Diese Anordnung hat den Nachteil, daß das Dieselgeneratoraggregat für Wartungszwecke schlecht zugänglich ist.Today there is often the task of using such payload vehicles on the one hand in certain operating phases in closed rooms or other rooms in which No exhaust gases are allowed to drive and in other phases of operation outdoors or other rooms in which exhaust gases are permitted, so long distances with so great Speed or so high a train load that driving these routes with battery current with regard to the charge capacity of the battery and its only limited rechargeability would be uneconomical. It is known about this Purpose of using vehicles that are equipped with a diesel generator set except with the battery are equipped, which is put into operation for driving outdoors and the Driving electric motors are fed by the generator. In the previously known vehicles of this type is struc- ture has been assumed of the design of a vehicle with a purely battery-electric drive, in which the battery is arranged in a space open to the top and lifted out at the top and can be used and a smaller battery is used in this room than in the normal state and the diesel generator set is in the battery room that remains free used. This arrangement has the disadvantage that the diesel generator set for Is difficult to access for maintenance purposes.

Der Erfindung liegt die Aufgabe zugrunde, ein Fahrzeug zu schaffen, bei dem sowohl der Batteriewechsel als auch die Wartung des aus Brennkraftmaschine und Generator bestehenden Aggregates leicht möglich sind.The invention is based on the object of creating a vehicle, in which both the battery change and the maintenance of the internal combustion engine and generator of existing gensets are easily possible.

Zur Lösung dieser Aufgabe ist vorgesehen, daß das aus Brennkraftmaschine und Elektrogenerator bestehende Aggregat oberhalb der Batterie angeordnet ist. Dadurch ist dieses Aggregat leicht zugänglich, andererseits ergibt sich dadurch, daß die relativ schwere Batterie relativ tief angeordnet ist, eine tiefe Schwerpunktlage für das Gesamtfahrzeug.To solve this problem it is provided that the internal combustion engine and electrical generator existing aggregate is arranged above the battery. Through this this unit is easily accessible, on the other hand it results from the fact that the relatively heavy battery is located relatively low, a low center of gravity for the entire vehicle.

Besonders vorteilhaft ist, wenn das Fahrzeug mit einer Plattform ausgestaltet ist und die Batterie unterhalb der Plattformebene zur Seite herausziehbar angeordnet ist und das aus Brennkraftmaschine und Generator bestehende Aggregat oberhalb der Plattformebene angeordnet ist, wobei gegebenenfalls hinter diesem aus Brennkraftmaschine und Generator bestehenden Aggregat noch ein Teil der Plattform als Restladefläche für Nutzlast oder für Ballastgewichte zum Belasten der Treibachse zum Ziehen großer Zuglasten verbleibt. Ein Wechsel der zur Seite herausfahrbaren Batterien ist dann gut möglich und die Zugänglichkeit zur Brennkraftmaschine ist ebenfalls gut und eine Belüftung des Raums, in dem sich Brennkraftmaschine und Generator befinden, ist ebenfalls leicht möglich ohne die Gefahr, daß Wärme unnötig zur Batterie hingeführt wird.It is particularly advantageous if the vehicle is designed with a platform and the battery is arranged below the platform level so that it can be pulled out to the side is and the unit consisting of the internal combustion engine and generator above the Platform level is arranged, optionally behind this from internal combustion engine and generator existing aggregate still part of the platform as residual loading area for payload or for ballast weights to load the drive axle to pull large ones Tensile loads remains. It is then necessary to change the batteries that can be pulled out to the side well possible and the accessibility to the internal combustion engine is also good and ventilation of the room, in which the internal combustion engine and generator are located is also easily possible without the risk of unnecessary heat to the battery is led.

Eine besonders vorteilhafte Anordnung ergibt sich, wenn die Brennkraftmaschine quer zur Fahrzeuglängsachse angeordnet ist und der Generator unmittelbar mit der Kurbelwelle bzw. dem Schwungrad der Brennkraftmaschine gekoppelt ist, sofern die Breite des Fahrzeuges und die Länge von Brennkraftmaschine und Generator dies zulassen oder, wenn der Generator neben der Brennkraftmaschine derart angeordnet ist, daß die Kurbelwelle der Brennkraftmaschine und die Welle des Generators parallel zu einander liegen. Sind zwei Generatoren vorhanden, kann der eine mit der Brennkraftmaschine gekoppelt und der andere neben dieser angeordnet sein.A particularly advantageous arrangement is obtained when the internal combustion engine is arranged transversely to the longitudinal axis of the vehicle and the generator directly with the Crankshaft or the flywheel of the internal combustion engine is coupled, provided that the The width of the vehicle and the length of the internal combustion engine and generator allow this or, if the generator is arranged next to the internal combustion engine in such a way that the crankshaft of the internal combustion engine and the shaft of the generator parallel to it lie to each other. If there are two generators, one can be connected to the internal combustion engine coupled and the other be arranged next to this.

Die Erfindung bezieht sich somit auf ein Fahrzeug mit einem oder mehreren mit Gleichstrom beaufschlagbaren Elektromotor bzw. Elektromotoren für den Fahrantrieb, gegebenenfalls Elektromotoren für weitere sonstige Antriebe und mit einer Batterie und mit einem aus einer Brennkraftmaschine, vorzugsweise einem Dieselmotor,und einem Generator bestehenden Aggregat, wobei wahlweise in einem Schaltzustand die Batterie über Steuerorgane an den Fahrmotor bzw. Fahrmo--toren angeschlossen ist oder wahlweise in einem anderen Betriebszustand der Generator des aus Brennkraftmaschine und Generator bestehenden Aggregates an den Elektromotor bzw. die Elektromotoren angeschlossen ist, wobei dieses Fahrzeug dadurch gekennzeichnet ist, daß das aus Brennkraftmaschine und Generator bestehende Aggregat oberhalb der Batterie angeordnet ist wobei vorzugsweise die Batterie zwischen den Achsen unterhalb einer Plattformebene zur Seite herausziehbar angeordnet ist.The invention thus relates to a vehicle with one or more electric motor or electric motors for the drive that can be charged with direct current, possibly electric motors for other other drives and with a battery and with one of an internal combustion engine, preferably a diesel engine, and one Generator existing aggregate, with the battery optionally in one switching state is connected to the traction motor or traction motors via control units, or alternatively in another operating state the generator of the internal combustion engine and generator existing unit connected to the electric motor or the electric motors is, this vehicle is characterized in that the internal combustion engine and generator existing aggregate is arranged above the battery, preferably the battery can be pulled out to the side between the axles below a platform level is arranged.
