Description

Die Erfindung betrifft eine Straßenbaumaschine, insbesondere einen Straßenfertiger oder einen Beschicker gemäß den Oberbegriffen der Ansprüche 1 und 11.The invention relates to a road construction machine, in particular a paver or a feeder according to the preambles of claims 1 and 11.

Straßenbaumaschinen, insbesondere Straßenfertiger und Beschicker werden beispielsweise von einem Lastkraftwagen oder anderen Transportmitteln mit Straßenbaumaterial versorgt. Straßenfertiger dienen zur Herstellung von Straßenbelägen aus Asphalt oder einem anderen Straßenbaumaterial, wie beispielsweise Beton. Beschicker dienen dazu, Straßenfertiger mit Straßenbaumaterial zu versorgen. Lastkraftwagen oder dergleichen kippen das Straßenbaumaterial entweder direkt in einen Vorratsbehälter oder Bunker bzw. in eine Mulde des Straßenfertigers oder in einen Vorratsbehälter des Beschickers, der das Material dann zu einem Straßenfertiger, insbesondere in einen Vorratsbehälter des Straßenfertiger, weiter transportiert. Straßenfertiger zur gleichzeitigen Herstellung mehrerer Schichten eines Straßenbelags verfügen über mehrere Vorratsbehälter für unterschiedliche Straßenbaumaterialien.Road construction machines, especially road pavers and feeders are supplied for example by a truck or other means of transport with road construction material. Pavers are used to make asphalt pavements or other road construction material, such as concrete. Feeders are used to supply road pavers with road construction material. Lorries or the like tilt the road construction material either directly into a reservoir or bunker or in a trough of the paver or in a reservoir of the feeder, which then transports the material to a paver, especially in a reservoir of the paver on. Road pavers for the simultaneous production of several layers of a road surface have several reservoirs for different road construction materials.

Beispielsweise aus JP H7 48810 A oder JP 2001 020214 A ist bekannt, dass die Vorratsbehälter zwei Behälterhälften aufweisen, welche relativ zueinander zusammenklappbar und auseinanderklappbar sind. In einem Scheitelbereich, in dem beide Behälterhälften mit einem Fahrgestell oder Chassis verbunden sind, ist ein Förderorgan angeordnet, welches das Straßenbaumaterial aus dem Vorratsbehälter entgegen einer Fertigungsrichtung der Straßenbaumaschine zu einer Einbaubohle bzw. zu einem weiteren Förderorgan transportiert.For example JP H7 48810 A or JP 2001 020214 A It is known that the storage containers have two container halves which are collapsible relative to each other and can be unfolded. In a vertex area in which both container halves are connected to a chassis or chassis, a conveying member is arranged, which transports the road building material from the reservoir against a production direction of the road construction machine to a screed or to another conveying member.

Für den Transport der Straßenbaumaschine oder für den Fall, dass sich nur noch sehr wenig Straßenbaumaterial in dem Vorratsbehälter befindet, ist es vorgesehen, dass die Behälterhälften zusammenklappbar sind. Zur Befüllung bzw. Aufnahme von Straßenbaumaterial werden die Behälterhälften hingegen auseinandergeklappt, um das Aufnahmevolumen oder den Aufnahmeraum des Vorratsbehälters zu maximieren. In diesem Zustand ragen die Behälterhälften über die äußeren Abmessungen des Chassis weit hinaus.For the transport of the road construction machine or in the event that there is very little road construction material in the reservoir, it is provided that the container halves are collapsible. For filling or receiving road construction material, however, the container halves are unfolded to maximize the receiving volume or the receiving space of the reservoir. In In this condition, the container halves protrude far beyond the outer dimensions of the chassis.

Damit die beiden Behälterhälften zusammenklappbar sind, weisen die dem Chassis zugewandten Seitenwände der Behälterhälften üblicherweise miteinander korrespondierende Schrägen bzw. Aussparungen auf, die derart ausgebildet sind, dass die beiden Seitenwände der Behälterhälften beim Zusammenklappen nicht miteinander kollidieren und somit das Zusammenklappen blockieren. Der Nachteil dieser Ausgestaltung der Seitenwände ist, dass beim Befüllen des Vorratsbehälters mit Straßenbaumaterial selbiges über die dem Chassis zugewandten Seitenwände bzw. die Schrägen aus dem Vorratsbehälter hinausfallen kann. Das herabgefallene Straßenbaumaterial fällt auf den bereits hergestellten Straßenbelag und härtet aus. Des Weiteren kann das herabfallende Straßenbaumaterial auf den noch nicht fertiggestellten Untergrund fallen und den weiteren Herstellungsprozess behindern. Außerdem kann das herabfallende Straßenbaumaterial Sensorelemente oder andere Einrichtungen blockieren oder gar zerstören.So that the two container halves are collapsible, the side walls of the container halves facing the chassis usually have mutually corresponding bevels or recesses, which are designed such that the two side walls of the container halves do not collide with one another during folding and thus block the folding. The disadvantage of this embodiment of the side walls is that during filling of the reservoir with road construction material selbiges can fall beyond the chassis facing the side walls and the bevels from the reservoir. The fallen road construction material falls on the already prepared road surface and hardens. Furthermore, the falling road construction material may fall on the still unfinished ground and hinder the further manufacturing process. In addition, the falling road building material may block or even destroy sensor elements or other devices.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Straßenbaumaschine, insbesondere einen Straßenfertiger oder Beschicker, zu schaffen, bei dem beim Beschicken des Vorratsbehälters die Gefahr des Hinausfallens des Straßenbaumaterials aus dem Vorratsbehälter vermieden wird.The invention is therefore an object of the invention to provide a road construction machine, in particular a paver or feeder, in which when loading the reservoir, the risk of falling out of the road material from the reservoir is avoided.

Eine Straßenbaumaschine, insbesondere ein Straßenfertiger oder Beschicker zur Lösung dieser Aufgabe weist die Merkmale des Anspruchs 1 auf. Die Schilder sind dabei als Platten oder plattenartige Klappen ausgebildet. Durch die erfindungsgemäßen Schilder wird ein Hinausfallen des Straßenbaumaterials aus dem Vorratsbehälter vermieden. Somit weisen die Schilder gerade einen Freiheitsgrad quer zur Förderrichtung des Straßenbaumaterials auf. Wohingegen der Bewegungsfreiraum der Schilder parallel zur Förderrichtung des Straßenbaumaterials stark eingeschränkt bzw. nicht gegeben ist.A road construction machine, in particular a paver or feeder to solve this problem has the features of claim 1. The signs are designed as plates or plate-like flaps. The signs according to the invention prevent the road building material from falling out of the storage container. Thus, the signs just have a degree of freedom transverse to the conveying direction of the road building material. Whereas the freedom of movement of the signs parallel to the conveying direction of the road building material is severely limited or not given.

Bevorzugt sind die Schilder jeweils an einer dem Chassis zugewandten Außenfläche der Seitenwand, der Behälterhälften angeordnet. Somit sind die Schilder zwischen dem Chassis und den Seitenwänden der Behälterhälften angeordnet.Preferably, the signs are each arranged on an outer surface of the side wall facing the chassis, the container halves. Thus, the signs are located between the chassis and the side walls of the container halves.

Durch diese Anordnung der Schilder außerhalb des Aufnahmeraums der Behälterhälften wird das Aufnahmevolumen des Vorratsbehälters nicht reduziert.By this arrangement of the signs outside the receiving space of the container halves, the receiving volume of the reservoir is not reduced.

Erfindungsgemäß ist vorgesehen, dass die Schilder mit den Behälterhälften frei beweglich verbunden sind. Somit weisen die Schilder gerade einen Freiheitsgrad quer zur Förderrichtung des Straßenbaumaterials auf. Wohingegen der Bewegungsfreiraum der Schilder parallel zur Förderrichtung des Straßenbaumaterials stark eingeschränkt bzw. nicht gegeben ist.According to the invention it is provided that the signs are connected to the container halves freely movable. Thus, the signs just have a degree of freedom transverse to the conveying direction of the road building material. Whereas the freedom of movement of the signs parallel to the conveying direction of the road building material is severely limited or not given.

Erfindungsgemäß ist vorgesehen, dass die Schilder beim Auseinanderklappen der Behälterhälften in über die Seitenwände der Behälterhälften hinausragende Bereiche bewegbar sind und beim Zusammenklappen der Behälterhälften aus diesem Bereich hinausbewegbar sind. Somit werden die Schilder beim Auseinanderklappen der Behälterhälften gerade in die Aussparungen bzw. in den freiliegenden Bereich der Seitenwände hinein geschwenkt. Wohingegen beim Zusammenklappen der Behälterhälften gerade dieser Ausschnitt bzw. diese Aussparung der Seitenwände der Behälterhälften für ein kollisionsfreies Zusammenklappen wieder frei gegeben wird. Diese Bewegung erfolgt rein gravitatorisch, das heißt, dass keine weiteren Antriebe notwendig sind. Die Schilder folgen mit Ihrer Bewegung, bedingt durch ihre Masse, der Schwerkraft. Dies gestaltet sich als besonders vorteilhaft, da keine weiteren Antriebe, Aktuatoren oder dergleichen notwendig sind. Es ist allerdings auch im Rahmen der Erfindung, dass die Schilder durch einen mechanischen, elektrischen, hydraulischen oder dergleichen Antrieb bewegbar sind.According to the invention, when the container halves are unfolded, the labels can be moved into regions projecting beyond the side walls of the container halves and can be moved out of this region when the container halves are folded. Thus, when the container halves are unfolded, the labels are pivoted straight into the recesses or into the exposed area of the side walls. Whereas, when folding the container halves, this cutout or recess of the side walls of the container halves is released again for a collision-free folding. This movement is purely gravitational, which means that no further drives are necessary. The signs follow with their movement, due to their mass, of gravity. This is particularly advantageous since no further drives, actuators or the like are necessary. However, it is also within the scope of the invention that the signs are movable by a mechanical, electrical, hydraulic or similar drive.

Bevorzugt ist es vorgesehen, dass die Schilder an den Behälterhälften, insbesondere mit einem Eckbereich, pendelnd um eine Achse, an den Seitenwänden, aufgehängt sind. Vorzugsweise sind die Schilder als Dreiecke ausgebildet, können aber auch jegliche andere rechteckige bzw. polygonale Form aufweisen. Dadurch, dass die Schilder mit einem Eckbereich an der Außenfläche der Seitenwand frei rotierend aufgehängt sind, dreht sich das Schild beim Zusammen- bzw. Auseinanderklappen der Behälterhälften um die Drehachse, und zwar zunächst so, dass der Schwerpunkt des Schildes sich immer unter der Drehachse befindet.Preferably, it is provided that the signs are suspended on the container halves, in particular with a corner region, swinging around an axis on the side walls. Preferably, the signs are formed as triangles, but may also have any other rectangular or polygonal shape. Characterized in that the signs are freely rotatably suspended with a corner on the outer surface of the side wall, the shield rotates when collapsing or unfolding of the container halves about the axis of rotation, and initially so that the center of gravity of the shield is always below the axis of rotation ,

Des Weiteren kann es bevorzugt vorgesehen sein, dass an dem Chassis, insbesondere einer Chassiswandung, mindestens zwei Bolzen, insbesondere zwei feststehende Bolzen, angeordnet sind, wobei jedem Schild mindestens ein Bolzen an der Chassiswandung zugeordnet ist. Bei den Bolzen kann es sich auch um stiftartige oder andersartig ausgebildete Vorsprünge handeln. Je nach Anforderung und äußeren Bedingungen, lassen sich die Bolzen entsprechend an dem Chassis befestigen. Die Bolzen sind zu jedem Zeitpunkt fest an dem Chassis befestigt und bewegen sich beim Auseinander- bzw. Zusammenklappen der Behälterhälften nicht. Vorzugsweise weisen die Bolzen eine Rundung auf, die mit Seitenkanten der Schilder zusammenwirken. Insbesondere kann es die Erfindung vorsehen, dass die Bolzen an dem Chassis derart angeordnet sind, dass die Schilder wenigstens beim Auseinanderklappen der Behälterhälften mit dem Bolzen in Kontakt treten und die Schilder durch die Bolzen aus einer hängenden Stellung in eine auf den Bolzen aufliegenden Stellung bewegbar sind. Beim Auseinanderklappen der Behälterhälften tritt eine Seitenkante des Schildes in Kontakt mit den Bolzen. Da das Schild über die Drehachse mit der Behälterhälfte verbunden ist und sich durch die Bewegung der Behälterhälfte um die Achse fortdreht, wird das Schild über den Bolzen gezogen. Dadurch, dass ein Eckbereich des Schildes drehbar mit der Behälterhälfte verbunden ist, bewegt sich das Schild aus der nahezu vertikalen Grundposition in eine eher horizontale Stellung oder Endposition. Das Schild wird somit durch die Drehachse und den Bolzen gehalten. Durch dieses "Überdenbolzenziehen" des Schildes bewegt sich das Schild in die zuvor freie Aussparung der Seitenfläche der Behälterhälfte. Somit wird das Schild durch den Bolzen durch das Auseinanderklappen aus einer hängenden Gleichgewichtsposition herausbewegt. Auch diese Bewegung wird ausschließlich durch die Gravitationskraft bedingt, weswegen keine weiteren Antriebe notwendig sind.Furthermore, it can preferably be provided that on the chassis, in particular a chassis wall, at least two bolts, in particular two fixed bolts, are arranged, each shield is associated with at least one bolt on the chassis wall. The bolts may also be pin-like or differently shaped projections. Depending on requirements and external conditions, the bolts can be attached to the chassis accordingly. The bolts are firmly attached to the chassis at all times and do not move when the container halves are unfolded or collapsed. Preferably, the bolts have a rounding, which cooperate with side edges of the signs. In particular, the invention may provide that the bolts are arranged on the chassis in such a way that the blades come into contact with the bolt at least when the container halves are unfolded and the blades can be moved by the bolts from a suspended position to a position resting on the bolt , When unfolding the container halves enters a side edge of the shield in contact with the bolt. Since the shield is connected to the container half via the axis of rotation and continues to rotate about the axis as a result of the movement of the container half, the shield is pulled over the bolt. Characterized in that a corner region of the shield is rotatably connected to the container half, moves the shield from the nearly vertical base position in a more horizontal position or end position. The shield is thus held by the axis of rotation and the bolt. Through this "Überdenbolzenziehen" of the shield, the shield moves into the previously free recess of the side surface of the container half. Thus, the shield is moved by the bolt by the unfolding from a suspended equilibrium position. This movement is also exclusively due to the gravitational force, which is why no further drives are necessary.

Bevorzugt ist an den Seitenwänden, insbesondere an den Außenflächen der Seitenwände der Behälterhälften jeweils mindestens ein Anschlag angeordnet. Diese Anschläge treten beim Zusammenklappen der Behälterhälften mit einer Seitenkante der Schilder in Kontakt und drücken somit das Schild über die Gleichgewichtslage hinaus in Richtung des anderen Schildes. Die Schilder der beiden Behälterhälften werden durch die Anschläge beinahe soweit aufeinander zubewegt, bis sie sich berühren. Beim Zusammenklappen der Behälterhälften rutschen die Seitenkanten der Schilder zunächst über die Bolzen, bis der Kontakt ganz aufgehoben wird.Preferably, in each case at least one stop is arranged on the side walls, in particular on the outer surfaces of the side walls of the container halves. These stops come in contact with one side edge of the signs when folding the container halves and thus push the shield beyond the equilibrium position in the direction of the other sign. The signs of the two container halves are moved by the stops almost to each other until they touch. When folding the container halves, the side edges of the labels first slide over the bolts until the contact is completely released.

Ein weiteres bevorzugtes Ausführungsbeispiel einer Straßenbaumaschine kann es vorsehen, dass an dem Chassis bzw. an einer Chassiswandung ein weiterer Anschlag angeordnet ist, der im zusammengeklappten Zustand der Behälterhälften als Abstandshalter zwischen den Schildern dient, insbesondere die Pendelbewegung der Schilder beschränkt. Dadurch entsteht ein Spalt zwischen den beiden aufeinander zubewegten Seitenkanten der Schilder, wodurch verhindert wird, dass diese, bedingt durch an der Chassiswandung haften gebliebenes Straßenbaumaterial, zusammenkleben.Another preferred embodiment of a road construction machine may provide that on the chassis or on a chassis wall, a further stop is arranged, which in the folded state of the container halves as a spacer between the Signs serves, in particular limited the pendulum movement of the signs. This creates a gap between the two mutually moved towards the side edges of the signs, thereby preventing them, due to stick together by adhering to the Chassiswandung road construction material stick together.

Gemäß einer weiteren vorteilhaften Ausgestaltungsmöglichkeit der Straßenbaumaschine ist es vorgesehen, dass die Schilder an mindestens einer Seitenkante eine Umrandung aufweisen, die derart ausgebildet ist, dass die Kanten der Umrandung beim Auseinander- und Zusammenklappen der Behälterhälften mit den Kanten von Schienen, die an den Behälterhälften angeordnet sind, eine gemeinsame Ebene bilden. Den Behälterhälften ist jeweils mindestens eine Schiene zugeordnet, die in Langlöchern verschiebbar sind, um einen Kontakt mit der Chassiswandung herzustellen. Dies dient zum Einen dem Abdichten, dass kein Straßenbelag ungewollt aus dem Vorratsbehälter herausfällt, aber auch als Abstreifhilfe, dass sich kein Straßenbaumaterial an dem Chassis festsetzt. Die Umrandungen der Schilder sind nun gerade derart dimensioniert und angeordnet, dass sie mit diesen Schienen der Behälterhälften korrespondieren und eine gemeinsame Dichtkante bzw. Abstreifkante bilden. Diese gemeinsame Kante besteht auch beim Auseinander- bzw. Zusammenklappen der Behälterhälften. Somit bilden die Umrandungen und die Schienen unabhängig vom Verschwenkungswinkel der Schilder stets eine gemeinsame Dicht- bzw. Abdichtkante. Dadurch wird zu jedem Zeitpunkt gewährleistet, dass kein Straßenbaumaterial den Vorratsbehälter unplanmäßig verlässt bzw. Straßenbaumaterial von dem Chassis abgekratzt wird.According to a further advantageous embodiment of the road construction machine, it is provided that the signs on at least one side edge have a border which is formed such that the edges of the border when unfolding and folding the container halves with the edges of rails, which are arranged on the container halves are to form a common plane. The container halves are each associated with at least one rail, which are displaceable in slots to make contact with the Chassiswandung. This serves on the one hand to seal that no road surface accidentally falls out of the reservoir, but also as Abstreifhilfe that no road construction material stuck to the chassis. The borders of the signs are now just dimensioned and arranged so that they correspond to these rails of the container halves and form a common sealing edge or scraping edge. This common edge is also when the container halves apart or folding. Thus, the borders and the rails always form a common sealing or sealing edge, regardless of the pivot angle of the signs. This ensures at all times that no road building material leaves the reservoir unscheduled or road construction material is scraped off the chassis.

Demnach ist es erfindungsgemäß vorgesehen, dass die Schilder entlang der Seitenwände der Behälterhälften, insbesondere die Umrandung der Schilder, relativ zu den Schienen der Behälterhälften derart angeordnet sind, dass sich beim Auseinander- und Zusammenklappen der Behälterhälften zwischen den Schildern und den Seitenwänden sowie zwischen den Umrandungen, den Schienen und dem Chassis keine Zwischenräume ausbilden.Accordingly, it is provided according to the invention that the signs along the side walls of the container halves, in particular the border of the signs, relative to the rails of the container halves are arranged such that when unfolding and folding the container halves between the signs and the side walls and between the borders , the rails and the chassis form no gaps.

Eine Straßenbaumaschine, insbesondere ein Straßenfertiger oder Beschicker zur Lösung der eingangs genannten Aufgabe weist die Merkmale des Anspruchs 11 auf. Demnach ist es vorgesehen, dass an einer dem Vorratsbehälter zugewandten Chassiswandung der Straßenbaumaschine mindestens zwei Schilder drehbar gelagert sind, wobei den Behälterhälften jeweils mindestens eines der Schilder zugeordnet ist. Die Schilder sind dabei als Platten oder plattenartige Klappen ausgebildet. Durch die erfindungsgemäßen Schilder wird ein Hinausfallen des Straßenbaumaterials aus dem Vorratsbehälter vermieden.A road construction machine, in particular a paver or feeder to solve the above-mentioned problem, has the features of claim 11. Accordingly, it is provided that at least two plates are rotatably mounted on a side facing the reservoir Chassiswandung the road construction machine, wherein the container halves is assigned at least one of the signs. The signs are thereby formed as plates or plate-like flaps. The signs according to the invention prevent the road building material from falling out of the storage container.

Bevorzugt kann es außerdem vorgesehen sein, dass die Schilder freibeweglich an der Chassiswandung quer zu einer Fertigungsrichtung der Straßenbaumaschine pendelnd um eine Achse aufgehängt sind, wobei die Schilder beim Auseinanderklappen der Behälterhälften aus einer ersten Stellung in eine zweite Stellung relativ zu Seitenwänden des Vorratsbehälters bewegbar sind. Die Schilder sind zwischen dem Chassis und den Seitenwänden der Behälterhälften angeordnet. Durch diese Anordnung der Schilder außerhalb des Aufnahmeraums der Behälterhälften wird das Aufnahmevolumen des Vorratsbehälters nicht reduziert. Die Schilder weisen gerade einen Freiheitsgrad quer zur Förderrichtung des Straßenbaumaterials auf. Wohingegen der Bewegungsfreiraum der Schilder parallel zur Förderrichtung des Straßenbaumaterials stark eingeschränkt bzw. nicht gegeben ist. Vorzugsweise sind die Schilder als Dreiecke ausgebildet, können aber auch jegliche andere rechteckige bzw. polygonale Form aufweisen. Dadurch, dass die Schilder mit einem Eckbereich an der Chassiswandung frei rotierend aufgehängt sind, dreht sich das Schild beim Zusammen- bzw. Auseinanderklappen der Behälterhälften um die Drehachse, und zwar vorzugsweise zunächst so, dass der Schwerpunkt des Schildes sich immer unter der Drehachse befindet.Preferably, it can also be provided that the signs are freely movable suspended on the chassis wall transversely to a production direction of the road construction machine about an axis, wherein the plates are movable when unfolding the container halves from a first position to a second position relative to side walls of the reservoir. The signs are located between the chassis and the side walls of the container halves. By this arrangement of the signs outside the receiving space of the container halves, the receiving volume of the reservoir is not reduced. The signs have just one degree of freedom transverse to the conveying direction of the road building material. Whereas the freedom of movement of the signs parallel to the conveying direction of the road building material is severely limited or not given. Preferably, the signs are formed as triangles, but may also have any other rectangular or polygonal shape. Characterized in that the signs are freely rotatably suspended with a corner on the chassis wall, the shield rotates when folding or unfolding the container halves about the axis of rotation, preferably initially so that the center of gravity of the shield is always below the axis of rotation.

Insbesondere kann es die Erfindung weiter vorsehen, dass an den Behälterhälften bzw. an den Seitenwänden der Behälterhälften mindestens zwei Bolzen, insbesondere zwei feststehende Bolzen, angeordnet sind, wobei jedem Schild mindestens ein Bolzen zugeordnet ist, wobei die Bolzen an den Seitenwänden derart angeordnet sind, dass die Schilder wenigstens beim Auseinanderklappen der Behälterhälften mit den Bolzen in Kontakt treten und die Schilder durch die Bolzen aus einer ersten Stellung in eine zweite Stellung bewegbar sind. Bei den Bolzen kann es sich auch um stiftartige oder andersartig ausgebildete Vorsprünge handeln. Je nach Anforderung und äußeren Bedingungen, lassen sich die Bolzen entsprechend an dem Chassis befestigen. Die Bolzen sind zu jedem Zeitpunkt fest an dem Chassis befestigt und bewegen sich beim Auseinander- bzw. Zusammenklappen der Behälterhälften nicht. Vorzugsweise weisen die Bolzen eine Rundung auf, die mit Seitenkanten der Schilder zusammenwirken. Insbesondere kann es die Erfindung vorsehen, dass die Bolzen an dem Chassis derart angeordnet sind, dass die Schilder wenigstens beim Auseinanderklappen der Behälterhälften mit dem Bolzen in Kontakt treten und die Schilder durch die Bolzen aus einer hängenden Stellung in eine auf den Bolzen aufliegenden Stellung bewegbar sind. Beim Auseinanderklappen der Behälterhälften tritt eine Seitenkante des Schildes in Kontakt mit den Bolzen. Da das Schild über die Drehachse mit der Chassiswandung verbunden ist und sich durch die Bewegung der Behälterhälfte um die Achse fortdreht, wird das Schild über den Bolzen gezogen. Dadurch, dass ein Eckbereich des Schildes drehbar mit der Chassiswandung verbunden ist, bewegt sich das Schild aus einer Grundposition in eine Endposition. Das Schild wird somit durch die Drehachse und den Bolzen gehalten. Durch dieses "Überdenbolzenziehen" des Schildes bewegt sich das Schild vorzugsweise in die zuvor freie Aussparung der Seitenfläche der Behälterhälfte. Diese Bewegung der Schilder wird ausschließlich durch die Gravitationskraft bedingt, weswegen keine weiteren Antriebe notwendig sind.In particular, the invention may further provide that at least two bolts, in particular two fixed bolts, are arranged on the container halves or on the side walls of the container halves, wherein each shield is assigned at least one bolt, wherein the bolts are arranged on the side walls in such a way that in that the signs come into contact with the bolts at least when the container halves are unfolded and the plates can be moved by the bolts from a first position to a second position. The bolts may also be pin-like or differently shaped projections. Depending on requirements and external conditions, the bolts can be attached to the chassis accordingly. The bolts are firmly attached to the chassis at all times and do not move when the container halves are unfolded or collapsed. Preferably, the bolts have a rounding, which cooperate with side edges of the signs. In particular, it can provide the invention that the bolts are arranged on the chassis such that the signs at least when unfolding the container halves contact the bolt in contact and the signs through the bolts from a hanging position in a on the bolt resting position are movable. When unfolding the container halves enters a side edge of the shield in contact with the bolt. Since the shield is connected to the chassis wall via the axis of rotation and continues to rotate about the axis as a result of the movement of the container half, the shield is pulled over the bolt. Characterized in that a corner region of the shield is rotatably connected to the Chassiswandung, the shield moves from a basic position to an end position. The shield is thus held by the axis of rotation and the bolt. By this "Überdenbolzenziehen" of the shield, the shield preferably moves into the previously free recess of the side surface of the container half. This movement of the signs is exclusively due to the gravitational force, which is why no further drives are necessary.

Ein weiteres Ausführungsbeispiel kann es vorsehen, dass an dem Chassis bzw. der Chassiswandung mindestens ein Anschlag angeordnet ist, der im zusammengeklappten Zustand der Behälterhälften als Abstandshalter zwischen den Schildern dient, insbesondere die Pendelbewegung der Schilder beschränkt. Dadurch entsteht ein Spalt zwischen den beiden aufeinander zubewegten Seitenkanten der Schilder, wodurch verhindert wird, dass diese, bedingt durch an der Chassiswandung haften gebliebenes Straßenbaumaterial, zusammenkleben.A further embodiment may provide that at least one stop is arranged on the chassis or the chassis wall, which serves as a spacer between the plates in the folded state of the container halves, in particular restricts the pendulum movement of the plates. This creates a gap between the two mutually moved towards the side edges of the signs, thereby preventing them, due to stick together by adhering to the Chassiswandung road construction material stick together.

Eine besonders vorteilhafte Weiterentwicklung der Erfindung kann es vorsehen, dass die Schilder an mindestens einer Seitenkante jeweils eine Umrandung aufweisen, die derart ausgebildet ist, dass die Kanten der Umrandungen beim Auseinander- und Zusammenklappen der Behälterhälften mit den Kanten von Schienen, die an den Behälterhälften angeordnet sind, in einer gemeinsamen Ebene liegen, vorzugsweise dass die Schilder entlang den Seitenwänden der Behälterhälften, insbesondere die Umrandungen der Schilder, relativ zu den Schienen der Behälterhälften, derart angeordnet sind, dass sich beim Auseinander- und Zusammenklappen der Behälterhälften zwischen den Schildern und den Seitenwänden sowie zwischen den Umrandungen, den Schienen und der Chassiswandung keine Zwischenräume ausbilden. Den Behälterhälften ist jeweils mindestens eine Schiene zugeordnet, die in Langlöchern verschiebbar sind, um einen Kontakt mit der Chassiswandung herzustellen. Dies dient zum Einen dem Abdichten, dass kein Straßenbelag ungewollt aus dem Vorratsbehälter herausfällt, aber auch als Abstreifhilfe, dass sich kein Straßenbaumaterial an dem Chassis festsetzt. Die Umrandungen der Schilder sind nun gerade derart dimensioniert und angeordnet, dass sie mit diesen Schienen der Behälterhälften korrespondieren und eine gemeinsame Dichtkante bzw. Abstreifkante bilden.A particularly advantageous development of the invention may provide that the signs have at least one side edge in each case a border which is formed such that the edges of the borders when unfolding and folding the container halves with the edges of rails, which are arranged on the container halves are, lie in a common plane, preferably that the signs along the side walls of the container halves, in particular the edges of the signs, relative to the rails of the container halves are arranged such that when unfolding and folding of the container halves between the signs and the side walls and between the borders, the rails and the chassis wall form no gaps. The container halves are each associated with at least one rail, which are displaceable in slots to make contact with the Chassiswandung. This serves on the one hand to seal that no road surface accidentally falls out of the reservoir, but also as Abstreifhilfe that no road construction material stuck to the chassis. The borders of the signs are now just dimensioned and arranged so that they correspond to these rails of the container halves and form a common sealing edge or scraping edge.

Diese gemeinsame Kante besteht auch beim Auseinander- bzw. Zusammenklappen der Behälterhälften. Somit bilden die Umrandungen und die Schienen unabhängig vom Verschwenkungswinkel der Schilder stets eine gemeinsame Dicht- bzw. Abdichtkante. Dadurch wird zu jedem Zeitpunkt gewährleistet, dass kein Straßenbaumaterial den Vorratsbehälter unplanmäßig verlässt bzw. Straßenbaumaterial von dem Chassis abgekratzt wird.This common edge is also when the container halves apart or folding. Thus, the borders and the rails always form a common sealing or sealing edge, regardless of the pivot angle of the signs. This ensures at all times that no road building material leaves the reservoir unscheduled or road construction material is scraped off the chassis.

Demnach ist es bevorzugt vorgesehen, dass die Schilder entlang der Seitenwände der Behälterhälften, insbesondere die Umrandung der Schilder, relativ zu den Schienen der Behälterhälften derart angeordnet sind, dass sich beim Auseinander- und Zusammenklappen der Behälterhälften zwischen den Schildern und den Seitenwänden sowie zwischen den Umrandungen, den Schienen und dem Chassis keine Zwischenräume ausbilden.Accordingly, it is preferably provided that the signs along the side walls of the container halves, in particular the border of the signs, relative to the rails of the container halves are arranged such that when unfolding and folding the container halves between the signs and the side walls and between the borders , the rails and the chassis form no gaps.

Vorliegende Erfindung ist gemäß den Oberbegriffen der Ansprüche 1 und 11 auf eine Straßenbaumaschine, insbesondere einen Straßenfertiger 10 oder Beschicker gerichtet. Auch wenn in der Fig. 1 ein Straßenfertiger 10 gezeigt ist, ist der Gegenstand der Erfindung, insbesondere die Gegenstände der Fig. 2 bis 7, ebenso auf einen nicht dargestellten Beschicker übertragbar. Durch Fig. 1 soll mit der Darstellung des Straßenfertigers 10 lediglich beispielhaft beschrieben werden, wie die Erfindung mit dem Herstellungsprozess eines Straßenbelages verbunden ist.The present invention is directed to a road construction machine, in particular a paver 10 or feeder according to the preambles of claims 1 and 11. Even if in the Fig. 1 a paver 10 is shown is the subject of the invention, in particular the objects of Fig. 2 to 7 , also on a not shown Feeder transferable. By Fig. 1 should be described with the representation of the paver 10 merely by way of example, as the invention is connected to the manufacturing process of a road surface.

Der in der Fig. 1 dargestellte Straßenfertiger 10 dient zur Herstellung von Straßenbelägen. Bevorzugt dient der Straßenfertiger 10 zur Herstellung von sogenannten Schwarzdecken, nämlich Straßenbelägen aus Asphalt. Der Straßenfertiger 10 kann aber auch zur Herstellung von Straßenbelägen aus anderen Materialien, wie beispielsweise Beton eingesetzt werden.The Indian Fig. 1 shown road paver 10 is used for the production of road surfaces. Preferably, the paver 10 is used for the production of so-called black slabs, namely asphalt pavements. The road paver 10 can also be used for the production of road surfaces made of other materials, such as concrete.

Der Straßenfertiger 10 ist selbstfahrend ausgebildet. Dazu verfügt dieser über eine zentrale Antriebseinheit 11, die beispielsweise einen Verbrennungsmotor aufweist, der Hydraulikpumpen zur Versorgung von Hydraulikmotoren und gegebenenfalls einen Generator zur Erzeugung von Energie für elektrische Antriebe oder Heizungen aufweist.The paver 10 is self-propelled. For this purpose, the latter has a central drive unit 11 which has, for example, an internal combustion engine which has hydraulic pumps for supplying hydraulic motors and optionally a generator for generating energy for electric drives or heaters.

Der Straßenfertiger 10 verfügt im Übrigen über ein Fahrwerk 12, dass in gezeigtem Ausführungsbeispiel als ein Raupenfahrwerk ausgebildet ist. Der Straßenfertiger 10 kann aber auch mit einem Radfahrwerk versehen sein. Das Fahrwerk 12 wird von der Antriebseinheit 11 derart angetrieben, dass sich der Straßenfertiger zur Herstellung des Straßenbelags in Fertigungsrichtung 13 fortbewegt.Incidentally, the road paver 10 has a running gear 12, which in the exemplary embodiment shown is designed as a tracked chassis. The paver 10 may also be provided with a wheel gear. The chassis 12 is driven by the drive unit 11 such that the paver for the production of the pavement in the production direction 13 moves.

In Fertigungsrichtung 13 gesehen, ist vor dem Fahrwerk 12 ein wannen- bzw. muldenartig ausgebildeter, auch als Bunker bezeichneter, Vorratsbehälter 14 angeordnet. Der Vorratsbehälter 14 nimmt einen Vorrat des zur Herstellung des Straßenbelags dienenden Materials auf. Durch ein beispielsweise als Kratzerförderer ausgebildetes Förderorgan 24 wird das noch heiße Straßenbaumaterial vom Vorratsbehälter 14 entgegen der Fertigungsrichtung 13 zum hinteren Ende 15 des Straßenfertigers 10 transportiert. Das hintere Ende 15 des Straßenfertigers 10 befindet sich in Fertigungsrichtung 13 gesehen hinter dem Fahrwerk 12 und der Antriebseinheit 11.Viewed in the production direction 13, a trough or trough-like design, also referred to as a bunker, reservoir 14 is arranged in front of the chassis 12. The reservoir 14 receives a supply of serving for the production of the road surface material. By means of a conveyor element 24 designed, for example, as a scraper conveyor, the still hot road building material is transported from the reservoir 14 counter to the production direction 13 to the rear end 15 of the paver 10. The rear end 15 of the paver 10 is seen in the production direction 13 behind the chassis 12 and the drive unit 11th

Am hinteren Ende 15 des Straßenfertigers 10 sind eine Verteilerschnecke 16 und mit Abstand dahinter eine Einbaubohle 17 angeordnet. Die Verteilerschnecke 16 und die Einbaubohle 17 sind auf- und abbewegbar. Zu diesem Zweck ist die Einbaubohle 17 an Tragarmen 18 angehängt. Die Tragarme 18 sind schwenkbar am Fahrwerk 12 des Straßenfertigers 10 gelagert. Hydraulikzylinder oder dergleichen verschwenken die Tragarme 18, um die Einbaubohle 17 anzuheben bzw. abzusenken.At the rear end 15 of the paver 10, a distributor screw 16 and at a distance behind a screed 17 are arranged. The auger 16 and the screed 17 are moved up and down. For this purpose, the screed 17 is attached to support arms 18. The support arms 18 are pivotally mounted on the chassis 12 of the paver 10. Hydraulic cylinders or the like pivot the support arms 18 to raise or lower the screed 17.

Zur Versorgung des Straßenfertigers 10 bzw. des Vorratsbehälters 14 mit Straßenbaumaterial, fährt ein nicht dargestellter Lastkraftwagen rückwärts an das vordere Ende 19 des Straßenfertigers 10 und schüttet das Straßenbaumaterial in den Vorratsbehälter 14. Damit das Aufnahmevolumen des Vorratsbehälters 14 maximal ist, werden zwei Behälterhälften 20, 21 des Vorratsbehälters 14 auseinandergeklappt (Fig. 2). Dabei drehen sich die Behälterhälften 20, 21 um Drehachsen 22, 23 die oberhalb des Fahrwerkes 12 angeordnet sind. Der Bereich zwischen den Behälterhälften 20, 21 bzw. den Drehachsen 22, 23 gibt den Blick frei auf das, beispielsweise als Kratzerförderer ausgebildete Förderorgan 24. Wie oben bereits dargestellt, wird durch dieses Förderorgan 24 das Straßenbaumaterial im Fall eines Straßenfertigers 10 der Einbaubohle 17 zugeführt. Für den Fall, dass der Vorratsbehälter 14 einem Beschicker beigeordnet ist, fördert das Förderorgan 24 das Straßenbaumaterial zu einem weiteren Förderer oder direkt in einen Vorratsbehälter 14 einer weiteren Straßenbaumaschine.To supply the road paver 10 and the reservoir 14 with road construction material drives a truck, not shown backwards to the front end 19 of the paver 10 and pours the road construction material into the reservoir 14. Thus, the receiving volume of the reservoir 14 is a maximum, two container halves 20, 21 of the reservoir 14 unfolded ( Fig. 2 ). The container halves 20, 21 rotate about axes of rotation 22, 23 which are arranged above the chassis 12. The area between the container halves 20, 21 or the axes of rotation 22, 23 gives the view freely, for example, designed as a scraper conveyor conveyor 24. As already shown above, the road construction material in the case of a paver 10 of the screed 17 is supplied by this conveyor member 24 , In the event that the reservoir 14 is assigned to a feeder, the conveying member 24 promotes the road construction material to another conveyor or directly into a reservoir 14 of another road construction machine.

Sowohl die Antriebseinheit 11, das Fahrwerk 12, die Tragarme 18 als auch der Vorratsbehälter 14 sind dem Fahrgestell oder auch Chassis 25 des Straßenfertigers 10 zugeordnet.Both the drive unit 11, the chassis 12, the support arms 18 and the reservoir 14 are associated with the chassis or chassis 25 of the paver 10.

Die Behälterhälften 20, 21 schließen zusammen einen Aufnahmeraum 26 für das Straßenbaumaterial ein. Die einzelnen Behälterhälften 20, 21 weisen jeweils einen Boden 27, 28 auf, der sowohl mit den Drehachsen 22, 23 verbunden ist, als auch mit jeweils zwei weiteren Seitenwandungen. Die in Fertigungsrichtung 13 an hinteren Teilen der Behälterhälften 20, 21 positionierten Seitenwände 29, 30 grenzen direkt an einer Chassiswandung 31. Die Seitenwände 29, 30 sind derart ausgebildet, dass beim Zusammenklappen der Aufnahmeraum 26 minimiert werden kann, ohne dass die Seitenwände 29, 30 miteinander kollidieren.The container halves 20, 21 together enclose a receiving space 26 for the road building material. The individual container halves 20, 21 each have a bottom 27, 28, which is connected both to the axes of rotation 22, 23, as well as with two further side walls. The side walls 29, 30 positioned in the direction of production 13 on the rear parts of the container halves 20, 21 adjoin directly on a chassis wall 31. The side walls 29, 30 are designed in such a way that, on folding, the receiving space 26 can be minimized without the side walls 29, 30 collide with each other.

Damit zwischen die Seitenwandungen 29, 30 und der Chassiswandung 31 kein Straßenbaumaterial fällt, sind den Seitenwänden 29, 30 Schienen 32, 33 zugeordnet. Diese Schienen 32, 33 lassen sich in Fertigungsrichtung 13 derart verschieben, dass sie einen dichtenden Kontakt mit der Chassiswandung 31 bilden. Die Schienen 32, 33 dienen außerdem dazu, Straßenbaumaterial, welches an der Chassiswandung 31 klebt beim Zusammenklappen der Behälterhälften 20, 21 abzukratzen.So that no road construction material falls between the side walls 29, 30 and the chassis wall 31, the side walls 29, 30 rails 32, 33 are assigned. These rails 32, 33 can be moved in the production direction 13 such that they form a sealing contact with the chassis wall 31. The rails 32, 33 also serve to scrape off road building material adhering to the chassis wall 31 upon collapse of the container halves 20, 21.

Erfindungsgemäß weisen die Seitenwände 29, 30 Schilder 34, 35 auf. Diese Schilder 34, 35 sind als plattenartige Klappen oder einfache Platten ausgebildet. Die hier dargestellten Schilder 34, 35 weisen eine Dreiecksform auf, können aber auch jede andere polygonale bzw. beliebige geometrische Form aufweisen.According to the invention, the side walls 29, 30 have signs 34, 35. These plates 34, 35 are formed as plate-like flaps or simple plates. The signs 34, 35 shown here have a triangular shape, but may also have any other polygonal or any geometric shape.

Gemäß der vorliegenden Erfindung können die Schilder 34, 35 sowohl an den Seitenwänden 29, 30 des Vorratsbehälters 14 als auch an einer Chassiswandung 31 des Chassis 25 gelagert sein. Im Folgenden wird beispielhaft die Ausführungsform dargestellt, bei der die Schilder 34, 35 an den Seitenwänden 29, 30 installiert sind.According to the present invention, the plates 34, 35 may be mounted both on the side walls 29, 30 of the storage container 14 and on a chassis wall 31 of the chassis 25. The following is an example of the embodiment in which the signs 34, 35 are installed on the side walls 29, 30.

In Fig. 3 ist eine Rückansicht der Behälterhälften 20, 21, in Fertigungsrichtung 13 betrachtet, dargestellt. Dadurch ist zu erkennen, dass die Schilder 34, 35 beweglich, bzw. drehbar um Achsen 36, 37 an den Seitenwänden 29, 30 befestigt sind. Gemäß der vorliegenden Erfindung sind die hier dargestellten Schilder 34, 35 den Seitenwänden 29, 30 frei beweglich, insbesondere pendelnd den Achsen 36, 37 zugeordnet. Die Schilder 34, 35 werden in dem in Fig. 3 dargestellten auseinandergeklappten Zustand der Behälterhälften 20, 21 durch nicht dargestellte Bolzen 38, 39 in ihrer horizontalen Positionierung gehalten. In dieser Stellung decken die Schilder 34, 35 gerade einen ansonsten freien Bereich zwischen den Seitenwänden 29, 30 und der Chassiswandung 31 ab. Somit verhindern die Schilder 34, 35, dass im ausgeklappten Zustand der Behälterhälften 20, 21 bzw. bei der Aufnahme von Straßenbaumaterial selbiges durch die ansonsten freie Öffnung zwischen den Seitenwänden 29, 30 und der Chassiswandung 31 auf den Untergrund oder den Straßenfertiger 10 herabfällt.In Fig. 3 is a rear view of the container halves 20, 21, viewed in the production direction 13, shown. As a result, it can be seen that the plates 34, 35 are movably mounted or rotatable about axes 36, 37 on the side walls 29, 30. According to the present invention, the signs 34, 35 shown here, the side walls 29, 30 freely movable, in particular oscillating the axes 36, 37 assigned. The plates 34, 35 are in the in Fig. 3 illustrated unfolded state of the container halves 20, 21 held by not shown bolts 38, 39 in their horizontal positioning. In this position, the shields 34, 35 just cover an otherwise free area between the side walls 29, 30 and the chassis wall 31. Thus, prevent the signs 34, 35 that in the unfolded state of the container halves 20, 21 or in the reception of road construction material the same through the otherwise free opening between the side walls 29, 30 and the chassis wall 31 on the ground or paver 10 drops.

Damit die Schilder 34, 35 in der in Fig. 3 dargestellten Stellung eine dichtende Wirkung zu der Chassiswandung 31 ausbilden, sind jeder Seitenkante 40, 41, 42 des Schildes 34 sowie jeder Seitenkante 43, 44, 45 des Schildes 35 jeweils eine Umrandung 46, 47, 48 bzw. 49, 50, 51 zugeordnet. Die Umrandungen 46, 47, 48, 49, 50, 51 sind gerade so bemessen, dass Ihre Breiten zusammen mit Breiten von Kanten 52, 53 der Seitenwände 29, 30 der Breiten der Schienen 32, 33 entsprechen. Somit bilden die Schienen 32, 33 zusammen mit den Umrandungen 46, 47, 48, 49, 50, 51 der Schilder 34, 35 eine Dichtungskante bzw. eine Abkratzkante bzgl. der Chassiswandung 31 (Fig. 4, Fig. 5). Es ist jedoch erfindungsgemäß durchaus denkbar, dass die Schilder 34, 35 nur eine, zwei oder mehr als drei entsprechende Umrandungen aufweisen, die eine ähnliche Funktion in Wechselwirkung mit der Chassiswandung 31 einnehmen, wie das hier dargestellte Ausführungsbeispiel.So that the signs 34, 35 in the in Fig. 3 illustrated position form a sealing effect to the Chassiswandung 31, each side edge 40, 41, 42 of the shield 34 and each side edge 43, 44, 45 of the shield 35 each have a border 46, 47, 48 and 49, 50, 51 assigned. The borders 46, 47, 48, 49, 50, 51 are just sized so that their widths, along with widths of edges 52, 53 of the side walls 29, 30 correspond to the widths of the rails 32, 33. Thus, the rails 32, 33 together with the borders 46, 47, 48, 49, 50, 51 of the plates 34, 35 form a sealing edge or a scraping edge with respect to the chassis wall 31 (FIGS. Fig. 4, Fig. 5 ). However, it is quite conceivable according to the invention that the plates 34, 35 have only one, two or more than three corresponding borders, which assume a similar function in interaction with the chassis wall 31, as the embodiment shown here.

Insbesondere beim Zusammenklappen der Behälterhälften 20, 21 werden die Schienen 32, 33 und die Umrandungen 46, 47, 48, 49, 50, 51 an der Chassiswandung 31 entlang bewegt und reinigen die Chassiswandung 31 somit von an dieser verbliebenen Straßenbaumaterial. Dabei wird das Straßenbaumaterial regelrecht von den Schienen 32, 33 und den Umrandungen 46, 47, 48, 49, 50, 51 abgekratzt.In particular, when folding the container halves 20, 21, the rails 32, 33 and the borders 46, 47, 48, 49, 50, 51 are moved along the chassis wall 31 and thus clean the chassis wall 31 of road construction material remaining thereon. The road construction material is literally scraped off the rails 32, 33 and the borders 46, 47, 48, 49, 50, 51.

In zusammengeklapptem Zustand der Behälterhälften 20, 21 ist der Aufnahmeraum 26 des Vorratsbehälters 14 minimiert. Diese Stellung der Behälterhälften 20, 21 eignet sich außerdem aufgrund der geringen Breite des Straßenfertigers 10 quer zur Fertigungsrichtung 13 besonders gut für den Transport des Straßenfertigers 10. In dieser in der Fig. 7 dargestellten Position hängen die Schilder 34, 35, von den Achsen 36, 37 gehalten, nach unten. Dabei können die Seitenkanten 40, 43 der Schilder 34, 35 parallel zu den Kanten 52, 53 der Seitenwände 29, 30 ausgerichtet sein. Die Umrandungen 46, 49 der Schilder 34, 35 befinden sich in dieser Stellung gegenüberliegend ausgerichtet und werden lediglich durch einen Anschlag 54, der zentral an der Chassiswandung 31 angeordnet ist, voneinander getrennt. Dieser Anschlag 54 bewirkt, dass sich die Seitenkanten 40, 43 der Schilder 34, 35 nicht berühren und so eventuell durch restliches Straßenbaumaterial miteinander verkleben.In the folded state of the container halves 20, 21 of the receiving space 26 of the reservoir 14 is minimized. This position of the container halves 20, 21 is also due to the small width of the paver 10 transverse to the production direction 13 particularly well for the transport of the paver 10. In this in the Fig. 7 shown position the signs 34, 35, held by the axles 36, 37, down. In this case, the side edges 40, 43 of the plates 34, 35 may be aligned parallel to the edges 52, 53 of the side walls 29, 30. The borders 46, 49 of the plates 34, 35 are aligned opposite each other in this position and are separated from each other only by a stop 54 which is arranged centrally on the chassis wall 31. This stop 54 causes the side edges 40, 43 of the plates 34, 35 do not touch and thus possibly stick together by remaining road construction material.

An den Außenflächen 55, 56 der Seitenwände 29, 30 befindet sich jeweils ein Anschlag 57, 58. Diese Anschläge 57, 58 an den Seitenwänden 29, 30 der Behälterhälften 20, 21 schieben beim Zusammenklappen der Behälterhälften 20, 21 die Schilder 34, 35 in ihre hängende Position, so dass die Schilder 34, 35 in ihrer in Fig. 7 dargestellten Grundstellung durch die Anschläge 57, 58 und den Anschlag 54 fixiert werden. Somit bewegen sich beim Zusammenklappen der Behälterhälften 20, 21 die Schilder 34, 35 lediglich durch den Einfluss der Anschläge 57, 58 und der Schwerkraft. Es ist jedoch auch denkbar, dass die Schilder 34, 35 durch Antriebe, wie beispielsweise mechanische, elektrische, hydraulische oder sonstige Antriebe aus ihrer horizontalen Position in die hängende Stellung - und zurück - bewegt werden.On the outer surfaces 55, 56 of the side walls 29, 30 is in each case a stop 57, 58. These stops 57, 58 on the side walls 29, 30 of the container halves 20, 21 push the collapse of the container halves 20, 21, the signs 34, 35 in their hanging position, leaving the signs 34, 35 in their in Fig. 7 illustrated basic position by the stops 57, 58 and the stop 54 are fixed. Thus, when folding the container halves 20, 21, the signs 34, 35 move only by the influence of the stops 57, 58 and gravity. However, it is also conceivable that the plates 34, 35 are moved by actuators, such as mechanical, electrical, hydraulic or other drives from its horizontal position to the hanging position - and back -.

Beim Auseinanderklappen der Behälterhälften 20, 21 folgen die Schilder 34, 35 wieder dem Einfluss der Schwerkraft und drehen sich um die Achsen 36, 37. Damit die Schilder 34, 35 in die Fig. 1 bis 6 dargestellte horizontale Stellung gelangen, um den Verlust von Straßenbaumaterial zu vermeiden, sind der Chassiswandung 31 die bereits erwähnten Bolzen 38, 39 zugeordnet. Während des Auseinanderklappens treten Seitenkanten der Schilder 34, 35 mit den Bolzen 38, 39 in Kontakt. Durch die Fortführung des Auseinanderklappens der Behälterhälften 20, 21 werden die Schilder 34, 35 über die Bolzen 38, 39 gezogen und somit in ihre beispielsweise in Fig. 6 dargestellte horizontale Stellung geschoben bzw. verschwenkt. Auch bei dieser Bewegung sind keinerlei zusätzliche Antriebe notwendig - aber denkbar.When unfolding the container halves 20, 21 follow the signs 34, 35 again the influence of gravity and rotate about the axes 36, 37. Thus, the signs 34, 35 in the Fig. 1 to 6 shown horizontal position to avoid the loss of road construction material, the Chassiswandung 31 are the previously mentioned bolts 38, 39 assigned. During the unfolding occur side edges of the Signs 34, 35 with the bolts 38, 39 in contact. By continuing the unfolding of the container halves 20, 21, the plates 34, 35 are pulled over the bolts 38, 39 and thus in their example in Fig. 6 pushed horizontal position shown or pivoted. Even with this movement, no additional drives are necessary - but conceivable.

Somit wird beim Auseinanderklappen der Behälterhälften 20, 21 ein zuvor freier Bereich zwischen den Seitenwänden 29, 30 und der Chassiswandung 31 durch die Schilder 34, 35 verschlossen und beim Zusammenklappen der Behälterhälften 21, 22 die Schilder derart wegbewegt, dass die Kanten 52, 53 der Behälterhälften 20, 21 zusammenführbar sind.
