Abstract
Description
Die vorliegende Erfindung betrifft ein Winterdienst-Streufahrzeug mit einem Streugerät, umfassend einen Streustoff-Vorratsbehälter, eine Streustoff-Fördereinrichtung, eine von dieser beschickte Streueinrichtung mit mindestens einem rotierend angetriebenen Streuteller und eine die Fördereinrichtung und die Streueinrichtung steuernde Steuereinrichtung.The present invention relates to a winter utility scattering vehicle with a spreader, comprising a spreading material reservoir, a spreading material conveyor, a scattering device charged by the latter with at least one rotating driven spreading plate and a control device controlling the conveying device and the spreading device.
Streufahrzeuge der vorstehend angegebenen Art sind allgemein bekannt. Sie sind beispielsweise in den DE 3938147 A1, EP 835962 A1, DE 8813692 U1 und EP 627528 A1 beschrieben. Großes Augenmerk wurde in der Vergangenheit bei der Weiterentwicklung derartiger Streufahrzeuge gelegt einerseits auf eine möglichst weitgehende Vergleichmäßigung des Streubildes, d.h. möglichst geringe örtliche Abweichungen der tatsächlichen Streustoffverteilung von der vorgegebenen Streudichte, und andererseits eine Entlastung des Fahrers durch eine möglichst weitgehende Automatisierung des Streuvorgangs durch eine von der jeweiligen, automatisch erfaßten Position des Streufahrzeugs abhängige automatische Vorgabe von Streuparametern durch die Steuereinrichtung. Dies reflektiert die vorrangig maßgebliche Intention, Streufahrzeuge der hier in Rede stehenden Art prophylaktisch effektiv zur Glättebekämpfung einzusetzen, d.h. zu einem Zeitpunkt, zu dem sich das Streufahrzeug ungehindert über die jeweils zu bestreuende Verkehrsfläche bewegen kann.Gritting vehicles of the type mentioned above are well known. They are described, for example, in DE 3938147 A1, EP 835962 A1, DE 8813692 U1 and EP 627528 A1. Great attention has been paid in the past to the further development of such gritting vehicles, on the one hand, to making the spread image as homogenous as possible, i. the lowest possible local deviations of the actual spreading material distribution from the predetermined spreading density, and on the other hand a relief of the driver by as far as possible automation of the scattering by a dependent of the respective automatically detected position of the scattering vehicle automatic default of scattering parameters by the controller. This reflects the primarily authoritative intention to prophylactically effectively use scattering vehicles of the type in question for anti-smoothness, i. at a time when the spreader vehicle can move unhindered over the traffic area to be sprinkled.
Die vorliegende Erfindung hat sich zum Ziel gesetzt, ein Streufahrzeug der gattungsgemäßen Art zu schaffen, welches sich durch eine besondere Funktionalität in Situationen auszeichnet, in denen, gegebenenfalls glättebedingt, der Verkehrsfluß bereits zum Erliegen gekommen ist.The present invention has set itself the goal of creating a scattering vehicle of the generic type, which is characterized by a special functionality in situations in which, if necessary smoothness, the traffic flow has already come to a standstill.
Gelöst wird diese Aufgabenstellung gemäß der vorliegenden Erfindung dadurch, daß bei einem Winterdienst-Streufahrzeug der eingangs angegebenen Art mindestens ein Streuteller als Tiefstreuteller zum Betrieb in einer Tiefstreustellung mit einer Höhe von 25 cm oder weniger oberhalb der Fahrbahnoberfläche ausgeführt ist. Das erfindungsgemäße Streufahrzeug zeichnet sich mit anderen Worten dadurch aus, daß sich mit mindestens einem Streuteller Streustoff mit einer Abwurfhöhe von 25 cm oder weniger oberhalb der Fahrbahn ausbringen läßt. Dies gestattet den effizienten Einsatz des erfindungsgemäßen Streufahrzeugs auch in Stausituationen, insbesondere solchen infolge glättebedingter Unfälle. Denn das erfindungsgemäße Streufahrzeug kann beispielsweise durch die sog. "Rettungsgasse", wie sie bei einer Staubildung auf mehrspurigen Straßen zwischen zwei Fahrspuren für die Durchfahrt von Rettungsfahrzeugen freizuhalten ist, hindurch fahren und dabei wirksam die gesamte Fahrbahn bestreuen, weil der Streustoff, bedingt durch die Abwurfhöhe von 25 cm oder weniger oberhalb der Fahrbahnoberfläche, wirksam auch unter die beidseits der Rettungsgasse stehenden Fahrzeuge geschleudert werden kann. Mit herkömmlichen Streufahrzeugen, bei denen die Abwurfhöhe des Streutellers oberhalb der Fahrbahn mehr als 40 cm, typischerweise ca. 45 cm beträgt, ist dies nicht möglich. Besonders bevorzugt beträgt die Abwurfhöhe des als Tiefstreuteller ausgeführten Streutellers in der Tiefstreustellung nur 20 cm oder weniger.This object is achieved according to the present invention, characterized in that in a winter service scattering vehicle of the type specified at least one spreading plate is designed as a deep scattering plate for operation in a Tiefstreustellung with a height of 25 cm or less above the road surface. The scattering vehicle according to the invention is characterized in other words by the fact that can spread with at least one spreading plate scattering material with a discharge height of 25 cm or less above the roadway. This allows the efficient use of the scattering vehicle according to the invention also in congestion situations, in particular those due to smoothness-related accidents. Because the scattering vehicle according to the invention, for example, by the so-called. "Lane alley", as is to be kept clear in a congestion on multi-lane roads between two lanes for the passage of ambulances, and thereby effectively sprinkle the entire lane, because of the scattering, due to the Throwing height of 25 cm or less above the road surface, effectively can also be thrown under the standing on both sides of the emergency lane vehicles. With conventional spreading vehicles, in which the discharge height of the spreading plate above the roadway is more than 40 cm, typically about 45 cm, this is not possible. Particularly preferably, the discharge height of the spreading disc designed as a low spreading disc in the deep scattering position is only 20 cm or less.
Eine erste bevorzugte Weiterbildung des erfindungsgemäßen Streufahrzeugs zeichnet sich dadurch aus, daß die Streueinrichtung mindestens zwei Streuteller umfaßt, von denen einer als Tiefstreuteller und mindestens ein anderer als Standardstreuteller, d.h. mit einer Abwurfhöhe von 40 cm oder mehr oberhalb der Fahrbahnoberfläche ausgeführt ist. Bei einem solchermaßen weitergebildeten Streufahrzeug kann derjenige Streuteller, der als Tiefstreuteller ausgeführt ist, insbesondere dergestalt lageveränderbar aufgehängt sein, daß er wahlweise die Tiefstreustellung und eine Nichtgebrauchsstellung einnehmen kann. Für den Standard-Streueinsatz eines solchen Streufahrzeugs ist der als Tiefstreuteller ausgeführte Streuteller in seine Nichtgebrauchsstellung gebracht, in der er insbesondere weder das Ausbringen von Streustoff durch den Standardstreuteller behindert noch die Bodenfreiheit des Streufahrzeugs beeinträchtigt. Für den Streueinsatz im "Staubetrieb" wird hingegen der Standardstreuteller außer Betrieb gesetzt und der Tiefstreuteller in seine Tiefstreustellung gebracht und in Betrieb genommen, d.h. über die Fördereinrichtung mit Streustoff beschickt. Eine gleichzeitige Beschickung des Standardstreutellers kann gegebenenfalls möglich sein; im allgemeinen wird jedoch eine Beschickung des Tiefstreutellers und des mindestens einen Standardstreutellers über eine entsprechende Umstellung der Fördereinrichtung nur alternativ möglich sein.A first preferred embodiment of the scattering vehicle according to the invention is characterized in that the scattering device comprises at least two spreading discs, one of which as Tiefstreuteller and at least one other than standard scattering plate, i. is designed with a discharge height of 40 cm or more above the road surface. In such a further educated scattering vehicle that scattering plate, which is designed as a low-spreading plate, in particular be suspended in such a position variable that he can take either the Tiefstreustellung and a non-use position. For standard litter application of such a littering vehicle, the spreading plate designed as a low-spreading plate is brought into its non-use position, in which, in particular, it does not hinder the spreading of litter by the standard litter plate or impair the ground clearance of the littering vehicle. For the scattering operation in the "dust operation", however, the standard scattering plate is put out of operation and brought the Tiefstreuteller in its Tiefstreustellung and put into operation, i. fed with spreading material via the conveyor. A simultaneous loading of the standard scattering plate may possibly be possible; In general, however, a feed of the deep scattering plate and the at least one standard scattering plate via a corresponding changeover of the conveyor will only be possible as an alternative.
Indessen läßt sich die vorliegende Erfindung durchaus auch bei Streufahrzeugen umsetzen, die nicht über einen solchen zusätzlichen, ausschließlich beim "Staubetrieb" zum Einsatz gelangenden Streuteller verfügen. In diesem Fall ist mindestens ein Streuteller der Streueinrichtung des Streufahrzeugs dergestalt lageveränderbar aufgehängt, daß er wahlweise eine Standardstreustellung, in der die Höhe des Streutellers oberhalb der Fahrbahnoberfläche 40 cm oder mehr beträgt, und eine Tiefstreustellung mit einer Abwurfhöhe des Streutellers von 25 cm oder weniger oberhalb der Fahrbahnoberfläche einnehmen kann. Hierzu kann die aus dem Streuteller und dem zugehörigen Antrieb bestehende Baugruppe insbesondere längs einer Führung zwischen der Standardstreustellung und der Tiefstreustellung verschiebbar aufgehängt sein. Eine den Streustoff zu dem Streuteller leitende Streustoffschütte bzw. Streustoffrinne kann dabei insbesondere teleskopisch verlänger- und verkürzbar ausgeführt sein. Insoweit können bei einem solchermaßen weitergebildeten Streufahrzeug nach der vorliegenden Erfindung gewisse bauliche Parallelen zu einem solchen Streufahrzeug bestehen, wie es der DE 3726946 C2 in einem anderen Zusammenhang entnehmbar ist.In the meantime, the present invention can certainly also be applied to spreading vehicles which do not have such an additional, exclusively in the "storage operation" have used spreading discs available. In this case, at least one spreading plate of the spreading device of the spreading vehicle is suspended in such a variable position that he optionally a standard scattering position in which the height of the spreading plate above the road surface is 40 cm or more, and a deep scattering position with a discharge height of the spreading plate of 25 cm or less above the road surface can take. For this purpose, the assembly consisting of the spreading plate and the associated drive can in particular be displaceably suspended along a guide between the standard scattering position and the deep scattering position. In this case, a scattering material chute or scattering gutter which guides the scattering material to the spreading plate can in particular be designed to be telescopically extendible and shortenable. In that regard, in such a further developed scattering vehicle according to the present invention, certain constructional parallels to such a scattering vehicle exist, as it is the DE 3726946 C2 in another context can be removed.
Verfügt das erfindungsgemäße Streufahrzeug im Sinne der vorstehend erläuterten Weiterbildung über einen Streuteller, der aufgrund seiner spezifischen Aufhängung sowohl in einer Standardstreustellung als auch in einer Tiefstreustellung betrieben werden kann, so umfaßt die Steuereinrichtung besonders bevorzugt eine Kompensationsschaltung, welche bei Absenkung des Streutellers aus seiner Standardstreustellung in seine Tiefstreustellung die Drehzahl des Streutellers erhöht. Durch eine solche automatische, durch die Kompensationsschaltung bewirkte Erhöhung der Drehzahl beim Übergang vom Standard-Streubetrieb in den Staustreubetrieb durch Absenken des Streutellers aus seiner Standardstreustellung in seine Tiefstreustellung wird (auch) beim Staustreubetrieb die für den Streueinsatz auf der jeweiligen Streustrecke maßgebliche, durch die Fahrbahnbreite vorgegebene, an dem Bedienpult eingestellte Streubreite eingehalten, ohne daß der Fahrer des Streufahrzeugs eingreifen müßte.If the scattering vehicle according to the invention has a scattering plate which can be operated in a standard scattering position as well as in a deep scattering position due to its specific suspension, the control device particularly preferably comprises a compensation circuit which, when the spreading disc is lowered from its standard scattering position its Tiefstreustellung increases the speed of the spreading plate. By such an automatic, caused by the compensation circuit increase the speed during the transition from the standard spreading operation in the storage engine by Lowering the spreading plate from its standard scattering position into its deep scattering position is (also) the stowage operation for the scattering on the respective scattering relevant, given by the road width, set on the control panel spread, without the driver of the scattering vehicle would have to intervene.
Gemäß einer anderen Weiterbildung des erfindungsgemäßen Streufahrzeugs ist vorgesehen, daß sich die den Tiefstreuteller und dessen Antrieb umfassende Baugruppe in der Tiefstreustellung des Tiefstreutellers mittels einer Stützeinrichtung auf der Fahrbahnoberfläche abstützt. Insbesondere kann dabei die Stützeinrichtung ein auf der Fahrbahnoberfläche abrollendes Rad umfassen. Dies erweist sich als besonders vorteilhaft in Anbetracht dessen, daß der Tiefstreuteller in seiner Tiefstreustellung bestimmungsgemäß nur eine sehr geringe Höhe oberhalb der Fahrbahnoberfläche aufweist und somit potentiell durch Fahrbahnunebenheiten und/oder Hindernisse auf der Fahrbahn gefährdet ist. Die Gefahr, daß der Tiefstreuteller in seiner Tiefstreustellung beschädigt wird, ist dadurch maßgeblich reduziert, daß der Tiefstreuteller durch die Abstützung der betreffenden Baugruppe auf der Fahrbahnoberfläche entsprechenden Fahrbahnunebenheiten unmittelbar folgt. Eine gegebenenfalls vorgesehene Verstelleinrichtung, mittels derer sich die Höhe des Streutellers oberhalb der Fahrbahnoberfläche zwischen einer Standardstreustellung und einer Tiefstreustellung verändern läßt, ist dann, wenn sich der Streuteller in seiner Tiefstreustellung über eine Stützeinrichtung auf der Fahrbahnoberfläche abstützt, zweckmäßigerweise in eine Schwimmstellung geschaltet.According to another embodiment of the scattering vehicle according to the invention it is provided that the deep scattering plate and the drive comprehensive assembly is supported in the deep scattering position of the deep scattering plate by means of a support means on the road surface. In particular, the support means may comprise a rolling on the road surface wheel. This proves to be particularly advantageous in view of the fact that the Tiefstreuteller in its Tiefstreustellung intended only a very small height above the road surface and thus potentially endangered by road bumps and / or obstacles on the road. The risk that the Tiefstreuteller is damaged in its Tiefstreustellung, is significantly reduced by the fact that the Tiefstreuteller follows directly by the support of the relevant assembly on the road surface corresponding road bumps. An optionally provided adjusting device, by means of which the height of the spreading disc can be changed above the road surface between a standard scattering position and a deep scattering position, is expediently switched to a floating position when the spreading disc is supported in its deep scattering position by a supporting device on the road surface.
