Description

Die vorliegende Erfindung betrifft ein Kraftfahrzeug mit einer Vorrichtung zum Ausbringen von flüssigem Auftaumittel auf Verkehrsflächen gemäß dem Oberbegriff von Anspruch 1. Sie betrifft desweiteren gemäß dem Oberbegriff von Anspruch 8 eine Sprühvorrichtung zum Ausbringen von flüssigem Auftaumittel.The present invention relates to a motor vehicle with a device for applying liquid thawing agent to traffic areas according to the preamble of claim 1. It also relates to a spray device for applying liquid thawing agent according to the preamble of claim 8.

Ein gattungsgemäßes Kraftfahrzeug ist aus dem deutschen Gebrauchsmuster 1 929 048 bekannt. Bei dem bekannten Kraftfahrzeug handelt es sich um einen Lastkraftwagen, auf dessen Ladepritsche der Vorratsbehälter für das flüssige Auftaumittel aufgesetzt ist. Der Vorratsbehälter ist dabei so dimensioniert, daß er die Ladepritsche des Lastkraftwagens vollständig ausfüllt und so den gesamten für die mögliche Zuladung zur Verfügung stehenden Raum ausnutzt. Das Sprührohr ist entweder im Bereich der vorderen Stoßstange des Fahrzeuges oder an der hinteren unteren Kante des auf die Ladepritsche aufsetzbaren Vorratsbehälters vorgesehen. Eine vom Antriebsmotor des Trägerfahrzeugs angetriebene Laugenhochdruckpumpe ist im Motorraum des Trägerfahrzeuges untergebracht.A generic motor vehicle is known from German utility model 1 929 048. The known motor vehicle is a truck, on the loading platform of which the reservoir for the liquid thawing agent is placed. The storage container is dimensioned such that it completely fills the loading platform of the truck and thus uses the entire space available for the possible load. The spray tube is provided either in the area of the front bumper of the vehicle or on the rear lower edge of the storage container which can be placed on the loading platform. One from the drive motor of the carrier vehicle powered high pressure pump is housed in the engine compartment of the carrier vehicle.

Aus der FR-A-2 133 874 ist eine Sprühvorrichtung der in Anspruch 8 angegebenen Art bekannt. Über die Dimensionierung von deren einzelnen Komponenten im Verhältnis zu den Abmessungen des Trägerfahrzeugs enthält dieses Dokument keine Angaben. Ebensowenig ist die Anordnung der Komponenten der Sprühvorrichtung an dem Trägerfahrzeug und die Art von deren Befestigung beschrieben.From FR-A-2 133 874 a spray device of the type specified in claim 8 is known. This document contains no information about the dimensioning of their individual components in relation to the dimensions of the carrier vehicle. The arrangement of the components of the spraying device on the carrier vehicle and the type of fastening thereof are also not described.

In der CH-A-113 878 ist ein Apparat zum Anbau an ein Fahrzeug beschrieben, der zum Zerstäuben von Flüssigkeiten für verschiedene Zwecke dient. Der Zerstäubungsapparat umfaßt eine vertikale Hohlwelle und mehrere mit dieser verbundene Drahtgeflechtkästen. Diesen wird durch die Hohlwelle die zu zerstäubende, einem Vorratsbehälter entnommene Flüssigkeit zugeführt. Hohlwelle samt Drahtgeflechtkästen werden, von der Fahrzeugachse oder einem Elektromotor angetrieben, in Drehung versetzt, wodurch die in die Drahtgeflechtkästen gelangende Flüssigkeit in einen feinen Nebel zerschlagen wird.CH-A-113 878 describes an apparatus for attachment to a vehicle which is used for atomizing liquids for various purposes. The atomizer comprises a vertical hollow shaft and several wire mesh boxes connected to it. The liquid to be atomized and removed from a storage container is fed to the latter through the hollow shaft. Hollow shaft including wire mesh boxes, driven by the vehicle axle or an electric motor, are rotated, whereby the liquid entering the wire mesh boxes is broken up into a fine mist.

Weiterhin werden im Winterdienst zum Abstumpfen und/oder Auftauen vereister Verkehrsflächen Streufahrzeuge eingesetzt, bei denen es sich üblicherweise um normale Fahrgestelle von Schwer- oder Leicht-LKW mit auf die Ladepritsche aufgesetzten Streugutbehältern handelt. In diesen Behältern wird Sand, Splitt oder Salz oder eine Mischung hiervon transportiert; das Streugut wird über mechanische Transporteinrichtungen wie Schnecken oder Förderbänder auf einen rotierenden Streuteller gefördert, welcher das Streugut auf der Fahrbahnoberfläche verteilt.Furthermore, in winter service for blunting and / or thawing icy traffic areas, spreading vehicles are used, which are usually normal chassis of heavy or light trucks with spreading material containers placed on the loading platform. Sand, grit or salt or a mixture thereof is transported in these containers; The spreading material is conveyed via mechanical transport devices such as screws or conveyor belts onto a rotating spreading plate, which distributes the spreading material on the road surface.

Die bekannten Winterdienstfahrzeuge mit einer Vorrichtung zum Ausbringen von flüssigem Auftaumittel oder mit Streuaufsatz haben eine große Nutzlast, damit eine möglichst lange Strecke besprüht bzw. bestreut werden kann, bevor das Winterdienstfahrzeug zur Wiederbefüllung des Vorratsbehälters das Laugen- bzw. Streugutdepot ansteuern muß. Die bekannten Fahrzeuge haben sich unter Einsatzbedingungen, wo lange Strecken gestreut werden müssen, gut bewährt; unter diesen Bedingungen arbeiten sie wirtschaftlich.The known winter service vehicles with a device for dispensing liquid thawing agent or with a sprinkling attachment have a large payload, so that as long a route as possible can be sprayed or sprinkled before the winter service vehicle has to go to the lye or grit deposit to refill the storage container. The known vehicles have proven themselves well under operating conditions where long distances have to be spread; under these conditions they work economically.

Zum Bestreuen von Fußwegen ist desweiteren eine von der Firma Pfau-Kommunalgeräte unter der Bezeichnung ETS vertriebene Streueinrichtung bekannt, welche heckseitig an einem Geländewagen montierbar ist. Die Vorrichtung umfaßt einen Vorratsbehälter, aus welchem das Streugut in einer einstellbaren Dosierung nach unten rieselt. Nachteilig bei dieser Streuvorrichtung ist, daß sie die Achslastverteilung des mit ihr bestückten Fahrzeuges verschlechtert und zudem die Zugänglichkeit der Ladefläche des Geländewagens von hinten erheblich einschränkt.To sprinkle on footpaths is also one of the company Pfau-Kommunalgeräte under the name ETS distributed spreader known, which can be mounted on the rear of an off-road vehicle. The device comprises a storage container from which the spreading material trickles downwards in an adjustable dosage. The disadvantage of this spreading device is that it worsens the axle load distribution of the vehicle equipped with it and also considerably limits the accessibility of the loading area of the off-road vehicle from the rear.

Insbesondere zum Ende des Winters, bei entsprechenden meteorologischen Verhältsnissen aber auch gelegentlich während des Winters, sind die Straßen weitgehend schnee- und eisfrei; innerhalb eines Bezirkes bestehen dann nur noch wenige, spezifische Punkte (schattige Kurven, Walddurchfahrten und Brücken), welche wegen der Gefahr einer Glatteisbildung mit auftauenden Mitteln behandelt werden müssen. Besonders verkehrsgefährdend sind Stellen mit Schmelzwasserbildung infolge Sonneneinstrahlung, mit der Folge der Vereisung bei sinkenden Temperaturen. Um diese Gefahrenpunkte zu behandeln, haben die Winterdienstfahrzeuge häufig eine Anfahrtstrecke von vielen Kilometern Wegstrecke über trockene Fahrbahnen zurückzulegen. Unter diesen Bedingungen ist ein Einsatz mit den bekannten Winterdienstfahrzeugen, deren Gesamtgewicht im allgemeinen über 10 t liegt, außerordentlich unwirtschaftlich. Aus Kostengründen wird deshalb zum Teil darauf verzichtet, zum Ende des Winters hin die wenigen verbleibenden Gefahrenstellen innerhalb eines Streubezirkes abzustreuen bzw. mit Auftaumitteln zu besprühen. Für die Verkehrsteilnehmer erwachsen daraus besondere Gefahren, weil sie nach längeren Fahrtstrecken auf trockener Fahrbahn nicht mehr damit rechnen, daß sich z.B. in einer im Schatten liegenden Kurve oder auf einer Brücke, Glatteis bildet. Wer hier zu schnell fährt, ist besonders unfallgefährdet.Especially at the end of winter, with appropriate meteorological conditions but also occasionally during winter, the roads are largely free of snow and ice; there are then only a few specific points within a district (shady curves, forest passages and bridges) which must be treated with thawing agents because of the risk of ice formation. Places with melt water formation due to solar radiation, with the consequence of icing at falling temperatures, are particularly dangerous for traffic. In order to deal with these danger points, winter service vehicles often have to cover a distance of many kilometers on dry roads. Under these conditions is a Use with the known winter service vehicles, whose total weight is generally over 10 t, extremely uneconomical. For cost reasons, it is therefore partly avoided to sprinkle the few remaining danger spots within a spreading area towards the end of winter or to spray them with thawing agents. This creates particular dangers for road users, because after longer journeys on dry roads they no longer expect black ice to form, for example, in a curve lying in the shade or on a bridge. Those who drive too fast here are particularly at risk of accidents.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Fahrzeug zu schaffen, mit welchem bei Straßenverhältnissen mit nur wenigen, vereinzelten glatteisgefährdeten Stellen die Behandlung mit Auftaumittel im Interesse der Verkehrssicherheit unter wirtschaftlichen Bedingungen möglich ist. Gemäß einem weiteren Aspekt der Erfindung soll eine Sprühvorrichtung zum Ausbringen von flüssigem Auftaumittel auf Verkehrsflächen geschaffen werden, mit der sich ein bekanntes Streckenkontrollfahrzeug besonders einfach in ein Fahrzeug nach der Erfindung umrüsten läßt.The present invention has for its object to provide a vehicle with which the treatment with thawing agent in the interest of traffic safety under economic conditions is possible in road conditions with only a few, isolated areas exposed to black ice. According to a further aspect of the invention, a spray device for applying liquid thawing agent to traffic areas is to be created, with which a known route control vehicle can be converted particularly easily into a vehicle according to the invention.

Nach der Erfindung wird die zuerst angegebene Aufgabe durch ein Kraftfahrzeug mit den im kennzeichnen des Anspruchs 1 angegebenen Merkmalen gelöst. Der Lösung der zweiten angegebenen Aufgabenstellung dienen die im kennzeichnen des Anspruchs 8 angegebenen Merkmale einen Sprühvorrichtung. Im Rahmen der Erfindung vorgesehene Streckenkontrollfahrzeuge sind Fahrzeuge der Straßenbauverwaltung, die die regelmäßige Kontrolle des Straßenzustandes durchführen. Es sind über einen geschlossenen Aufbau verfügende Kastenwagen mit einem zulässigen Gesamtgewicht bis zu etwa 3,5 t. In ihrem Nutzraum werden - vor Witterungseinflüssen geschützt - Werkstatteinrichtungen samt Werkzeug, Motorsägen, Bodenbearbeitungsgeräte, Verkehrsschilder, Absperreinrichtungen und dergleichen transportiert; sie sind üblicherweise mit Funk ausgestattet und nahezu ständig im Einsatz. Im Sinne der vorliegenden Anmeldung sind "Streckenkontrollfahrzeuge" ihrem Typ nach Transporter, Klein- und Kleinst-LKW, wobei der geschlossene Aufbau zumeist über eine Hecktür zugänglich ist.According to the invention, the object specified first is achieved by a motor vehicle with the features specified in the characterizing part of claim 1. The solution to the second specified task are the features specified in the characterizing part of claim 8, a spray device. Route control vehicles provided in the context of the invention are vehicles of the road construction administration which carry out the regular monitoring of the road condition. They are closed box vans with a permissible total weight of up to around 3.5 t. Be in their usable space - before weather influences protected - transports workshop equipment including tools, chainsaws, tillage equipment, traffic signs, shut-off devices and the like; they are usually equipped with radio and are in almost constant use. For the purposes of the present application, "line inspection vehicles" are transporters, small and very small trucks in terms of their type, the closed body being accessible mostly via a rear door.

Gemäß der Erfindung werden also solche kontinuierlich oder periodisch im Einsatz befindliche Streckenkontrollfahrzeuge zusätzlich mit einer Vorrichtung zum Ausbringen von flüssigem Auftaumittel versehen; die ohnehin durchzuführenden Kontrollfahrten können somit gleichzeitig der Behandlung der wenigen Gefahrenpunkte mit Auftaumittel dienen. Statt der bisher geübten Praxis, daß nämlich ein Streckenkontrollfahrzeug über Funk ein Streufahrzeug zu den von ihm erkannten zu behandelnden Stellen dirigiert, kann bei Einsatz des erfindungsgemäßen Streckenkontrollfahrzeuges dieses sofort tätig werden. Die Vorrichtung zum Ausbringen von Auftaumittel ist weitgehend an den speziellen Einsatzzweck angepaßt. Durch die Verwendung eines flüssigen Auftaumittels kann die Vorrichtung besonders kompakt aufgebaut sein, wobei gleichzeitig das Auftaumittel besonders rasch wirkt. Durch das entsprechend der vorhandenen Ladefläche und Nutzlastreserve begrenzte Fassungsvermögen des Vorratsbehälters wird der Erkenntnis Rechnung getragen, daß bei den genannten Straßenverhältnissen selten mehr als zwei Kilometer Sprühstrecke als Summe aller einzelnen Sprüheinsätze eines Tages anfällt. Z.B. würde bei einer Fahrbahnbreite von 5 m und einer Ausbringmenge von 20 g/m², d.h. 100 g Salzlauge pro gefahrenem Meter Fahrbahnlänge, ein Tankinhalt von nur 200 l für eine Sprühstrecke von aufsummiert 2 km Fahrbahnlänge ausreichen. Gleichzeitig erlaubt es das begrenzte Fassungsvermögen des Vorratsbehälters, den Raumbedarf der Vorrichtung gering zu halten, so daß noch ausreichend Laderaum für die sonstige Zuladung der Streckenkontrollfahrzeuge verbleibt. Nachdem das Streckenkontrollfahrzeug nur unter den geschilderten speziellen Bedingungen zum Auftauen vereister Flächen eingesetzt wird, ist die Vorrichtung gemäß der Erfindung schließlich mittels eine Schnellmontage ermöglichender Befestigungsmittel an dem Streckenkontrollfahrzeug befestigt. Die Vorrichtung kann somit unter geringstem Aufwand an dem Streckenkontrollfahrzeug angebracht werden, wenn die Wetter- und Straßenverhältnisse dies geboten erscheinen lassen, bzw. abgebaut werden, um außerhalb der saisonbedingten Einsatzzeit Ladegewicht zu sparen.According to the invention, such route control vehicles continuously or periodically in use are additionally provided with a device for dispensing liquid thawing agent; the control runs to be carried out anyway can thus simultaneously serve to treat the few danger points with thawing agents. Instead of the practice previously practiced, namely that a route control vehicle directs a scatter vehicle to the locations to be treated that it recognizes by radio, the route control vehicle according to the invention can be used immediately. The device for applying thawing agent is largely adapted to the special purpose. By using a liquid thawing agent, the device can be constructed in a particularly compact manner be, at the same time the thawing agent acts particularly quickly. Due to the limited capacity of the storage container in accordance with the existing loading area and payload reserve, the knowledge is taken into account that, given the road conditions mentioned, there is rarely more than two kilometers of spraying distance as the sum of all the individual spraying operations in one day. For example, with a lane width of 5 m and a spread rate of 20 g / m², ie 100 g brine per meter of lane length, a tank capacity of only 200 l would be sufficient for a spray distance of 2 km lane length. At the same time, the limited capacity of the storage container allows the space requirement of the device to be kept low, so that there is still sufficient cargo space for the other payload of the route control vehicles. After the route control vehicle is used only under the described special conditions for thawing icy surfaces, the device according to the invention is finally attached to the route control vehicle by means of fasteners that enable quick assembly. The device can thus be attached to the route control vehicle with little effort, if the weather and road conditions make this appear necessary or be dismantled in order to save loading weight outside of the seasonal operating time.

Dazu ist bei einer Ausführungsform vorgesehen, daß der Vorratsbehälter an dem Streckenkontrollfahrzeug in Unterfluranordnung, bevorzugt neben dem Reserverad, montiert ist. Mit wenigen Handgriffen können der Vorratsbehälter und die übrigen Komponenten an der Unterseite des Fahrzeuges befestigt werden. Die Ladefläche des Streckenkontrollfahrzeuges steht im vollem Umfang zum Transport anderer Gegenstände zur Verfügung. Die Sprüheinrichtung kann ohne Eingriffe in das vorhandene Streckenkontrollfahrzeug eingebaut werden, insbesondere ohne Durchbrüche für Leitungen und dgl. vom Laderaum nach außen.For this purpose, in one embodiment it is provided that the storage container is mounted on the route control vehicle in an underfloor arrangement, preferably next to the spare wheel. The storage container and the other components can be attached to the underside of the vehicle in a few simple steps. The loading area of the route control vehicle is fully available for the transportation of other objects. The spraying device can be installed in the existing route control vehicle without interventions, in particular without openings for lines and the like from the cargo area to the outside.

Bei einer anderen Ausgestaltung der Erfindung ist der Vorratsbehälter im Inneren des geschlossenen Aufbaus des Streckenkontrollfahrzeuges angeordnet. Der Vorratsbehälter ist dabei in seinem Format an die bestehenden Platzverhältnisse angepaßt. Bevorzugt wird eine stehende oder liegende Anordnung eines flach ausgebildeten Vorratsbehälters.In another embodiment of the invention, the storage container is arranged inside the closed structure of the route control vehicle. The format of the storage container is adapted to the existing space. A standing or lying arrangement of a flat storage container is preferred.

Besonders vorteilhaft ist es, wenn die - insbesondere elektrisch angetriebene - Pumpe in oder an dem Vorratsbehälter integriert ist. Durch dieses Merkmal wird die Montage der Sprüheinrichtung abermals vereinfacht und beschleunigt, nachdem eine gesonderte Befestigung der Pumpe an dem Streckenkontrollfahrzeug entbehrlich ist.It is particularly advantageous if the - in particular electrically driven - pump is integrated in or on the storage container. This feature once again simplifies and accelerates the assembly of the spraying device after a separate attachment of the pump to the route control vehicle is not necessary.

Das mit den Sprühdüsen bestückte Sprührohr ist bevorzugt an, unter- oder innerhalb der hinteren Stoßstange des Streckenkontrollfahrzeuges quer zur Fahrtrichtung angeordnet. Diese Anordnung gestattet einerseits eine besonders einfache Montage, andererseits ist das Sprührohr geschützt und verdeckt untergebracht. Zudem wird, anders als beim Aufsprühen des Auftaumittels vor dem Fahrzeug, der auf die Fahrbahn aufgebrachte Film aus Salzlauge nicht sofort wieder von den Rädern des Fahrzeuges verdrängt und aufgeschleudert.The spray tube equipped with the spray nozzles is preferably arranged on, below or within the rear bumper of the route control vehicle, transversely to the direction of travel. On the one hand, this arrangement permits particularly simple assembly, on the other hand, the spray tube is protected and concealed. In addition, unlike spraying on the thawing agent in front of the vehicle, the film of brine applied to the roadway is not immediately displaced and spun off the vehicle's wheels.

Die an dem Sprührohr angeordneten Sprühdüsen sind zweckmäßigerweise unabhängig voneinander jeweils mittels eines Elektromagnetventils zu- bzw. abschaltbar. Hierdurch wird die Flexibilität beim Einsatz der Sprüheinrichtung erhöht, indem das flüssige Auftaumittel gezielt eingesetzt werden kann, beispielsweise nur am rechten, im Schatten liegenden Fahrbahnrand. Gleichzeitig wird, nachdem eine Anpassung der Sprühbreite und somit des ausgebrachten Auftaumittels an die örtlichen Gegebenheiten möglich ist, die Umwelt geschont und die maximale Sprühstrecke vergrößert.The spray nozzles arranged on the spray tube can expediently be switched on and off independently of one another by means of an electromagnetic valve. This increases the flexibility when using the spray device, since the liquid thawing agent can be used in a targeted manner, for example only on right edge of the road in the shade. At the same time, after the spray width and thus the defrosting agent can be adapted to the local conditions, the environment is protected and the maximum spray distance is increased.

Zur Betätigung der Pumpe ist in dem Fahrerhaus des Streckenkontrollfahrzeuges zweckmäßigerweise ein Steuerpult angeordnet, mit welchem vorteilhaft auch die Fördermenge der Pumpe eingestellt werden kann, wobei bevorzugt eine wegeabhängige Mengenregelung infrage kommt. Auch die Elektromagnetventile der individuell zu- und abschaltbaren Sprühdüsen werden zweckmäßigerweise von dem Steuerpult im Fahrerhaus aus betätigt.In order to actuate the pump, a control panel is expediently arranged in the driver's cab of the route control vehicle, with which the delivery rate of the pump can advantageously also be adjusted, with a path-dependent quantity control preferably being considered. The solenoid valves of the spray nozzles, which can be switched on and off individually, are expediently actuated from the control panel in the driver's cab.

Das Streckenkontrollfahrzeug 1 gemäß den Fig. 1 bis 4 besteht aus einem geschlossenen Kastenwagen. Bei der Ausgestaltung gemäß den Fig. 1 und 2 ist in seinem Heckbereich, d.h. hinter der Hinterachse unterhalb des Unterbodens ein Vorratsbehälter 2 für Salzlauge angebracht. Dazu sind an der Unterseite des Unterbodens Befestigungspunkte 3 vorgesehen, welche eine rasche Montage und Demontage des Vorratsbehälters gestatten. An dem Vorratsbehälter 2 ist seitlich eine elektrisch angetriebene Pumpe 4 installiert, welche über eine Saugleitung 5 mit dem Vorratsbehälter 2 und über eine Druckleitung 6 mit dem Sprührohr 7 in Verbindung steht.The route control vehicle 1 according to FIGS. 1 to 4 consists of a closed panel van. 1 and 2 in the rear area, i.e. behind the rear axle below the underbody a reservoir 2 for brine is attached. For this purpose, fastening points 3 are provided on the underside of the underbody, which allow the storage container to be assembled and disassembled quickly. An electrically driven pump 4 is installed on the side of the storage container 2 and is connected to the storage container 2 via a suction line 5 and to the spray pipe 7 via a pressure line 6.

Am Sprührohr 7 sind vier Sprühdüsen 8 angeordnet, welche nach hinten, unten gerichtet sind. Die beiden inneren Sprühdüsen sind dabei gerade nach hinten gerichtet, während die beiden äußeren Sprühdüsen seitwärts, auswärts gerichtet sind. Jeder Sprühdüse 8 ist dabei ein Elektromagnetventil 9 zugeordnet, mittels welchem die Zufuhr von Salzlauge zu der entsprechenden Sprühdüse ein- und ausgeschaltet werden kann.On the spray tube 7, four spray nozzles 8 are arranged, which are directed backwards, downwards. The two inner spray nozzles are directed straight backwards, while the two outer spray nozzles are directed sideways and outwards. Each spray nozzle 8 is one Electromagnetic valve 9 is assigned, by means of which the supply of brine to the corresponding spray nozzle can be switched on and off.

Im Fahrerhaus des Streckenkontrollfahrzeuges ist ein Steuerpult 10 angeordnet. Von dem Steuerpult aus kann einerseits über eine Pumpensteuerleitung 11 die Pumpe 4 ein- und ausgeschaltet sowie der Durchsatz reguliert werden. Mittels der Düsensteuerleitung 12 kann vom Steuerpult 10 aus jede der vier Sprühdüsen 8 zu- bzw. abgeschaltet werden, wodurch die Sprühbreite gesteuert werden kann.A control panel 10 is arranged in the driver's cab of the route control vehicle. From the control panel, the pump 4 can be switched on and off and the throughput can be regulated via a pump control line 11. By means of the nozzle control line 12, each of the four spray nozzles 8 can be switched on or off from the control panel 10, as a result of which the spray width can be controlled.

Der Vorratsbehälter 2 wird über einen - nicht dargestellten - Stutzen an seiner Rückwand befüllt. Zum Ablassen der beim Einsatz des Streckenkontrollfahrzeuges nicht verwendeten Salzlauge ist am Boden des Vorratsbehälters eine - ebenfalls nicht dargestellte - Ablaßöffnung vorgesehen.The reservoir 2 is filled via a - not shown - nozzle on its rear wall. To drain the brine that is not used when the route control vehicle is used, a drain opening - likewise not shown - is provided on the bottom of the storage container.

Das Streckenkontrollfahrzeug gemäß den Fig. 3 und 4 unterscheidet sich von demjenigen gemäß den Fig. 1 und 2 lediglich durch die andersartige Anordnung des Vorratsbehälters 2 samt der angebauten Einheit aus der Pumpe 4 und dem diese antreibenden Elektromotor. Und zwar ist bei dem Streckenkontrollfahrzeug gemäß den Fig. 3 und 4 der Vorratsbehälter im Inneren des geschlossenen Kastenaufbaus unmittelbar an der Rückwand der Fahrerkabine angeordnet. Die Druckleitung 6 wird am Rand der Ladefläche nach hinten geführt. Sie tritt im hinteren Bereich der Ladefläche nach unten durch den Boden hindurch ins Freie, so daß das letzte Ende der Druckleitung vor dem in der hinteren Stoßstange angeordneten Sprührohr 7 außerhalb des Fahrzeuges verläuft.The route control vehicle according to FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 only in the different arrangement of the storage container 2 together with the attached unit from the pump 4 and the electric motor driving it. And that is 3 and 4, the storage container in the interior of the closed box body is arranged directly on the rear wall of the driver's cab. The pressure line 6 is guided to the rear at the edge of the loading area. It occurs in the rear area of the loading area down through the floor into the open, so that the last end of the pressure line runs in front of the spray pipe 7 arranged in the rear bumper outside the vehicle.

Ob die Anordnung des Vorratsbehälters gemäß den Fig. 1 und 2 oder diejenige gemäß den Fig. 3 und 4 im Einzelfall die günstigere ist, hängt unter anderem von der üblichen Nutzung des Laderaumes ab. Wird häufig eine schwere Ausrüstung transportiert, kann die Anordnung gemäß den Fig. 3 und 4 zu einer günstigeren Gewichtsverteilung führen; spielt die Gewichtsverteilung nur eine untergeordnete Rolle, ist die Anordnung gemäß den Fig. 1 und 2 im allgemeinen zu bevorzugen, weil sie zu keinerlei Verringerung des Laderaumes im Inneren des Kastenaufbaus führt. In beiden Fällen ist ein ungehinderter Zugang zum Inneren des Laderaumes durch die Hecktür möglich.Whether or not the arrangement of the storage container according to FIGS. 1 and 2 or that according to FIGS. 3 and 4 is the more favorable one depends in part on the usual use of the loading space. If heavy equipment is frequently transported, the arrangement according to FIGS. 3 and 4 can lead to a more favorable weight distribution; if the weight distribution plays only a subordinate role, the arrangement according to FIGS. 1 and 2 is generally preferred because it does not lead to any reduction in the loading space inside the box body. In both cases, unhindered access to the interior of the cargo area is possible through the rear door.
