Description

The invention relates to a utility vehicle having a vehicle body structure comprising a floor structure and two side walls, a conveyor floor arranged between the side walls on an upper side of the floor structure, a conveyor floor deflection device arranged at a rear end of the floor construction, by means of which the conveyor floor from the top to a bottom of the Floor structure is deflected or guided around, and provided on the vehicle body and cooperating with the conveyor floor drive arrangement by means of which the conveyor floor along the floor construction and the side walls from the top via the conveyor floor deflection device is movable to the bottom.

The EP 2 332 773 A1 discloses a utility vehicle having a floor, at least one diverter provided at one end of the floor, a plurality of ground support parallel ropes, a conveyor belt disposed on the support ropes, at the ends of which the support ropes are secured with their ends, the support ropes and the conveyor belt from a top of the bottom around the diverter to a bottom of the bottom, and a traction means connected to the ends of the conveyor and comprising two ropes and a winch, by means of which the conveyor is movable relative to the ground.

A disadvantage of this commercial vehicle that arranged on the conveyor belt conveyed can occur in between the conveyor belt and the side walls provided column. For rapeseed as conveyed, e.g. oil leaking from the rape will pass through the fissure, associated with an undesirable loss of rapeseed oil. Other conveyed entering the column may e.g. lead to a stiffness and increased wear of the conveyor belt.

Proceeding from this, the present invention seeks to prevent the occurrence of arranged on the conveyor floor conveyed in provided for between the conveyor bottom and the side walls column in a commercial vehicle of the type mentioned or at least be able to reduce.

This object is achieved by a commercial vehicle according to claim 1. Preferred developments of the invention are given in the subclaims and in the following description.

The commercial vehicle according to the invention comprises a vehicle body comprising a floor structure and two side walls, a conveyor floor arranged between the side walls on an upper side of the floor structure, a conveyor floor deflecting means arranged at a rear end of the floor structure, by means of which the conveyor floor is deflected from the upper side to an underside of the floor construction or is guided around, and provided on the vehicle body and cooperating with the conveyor floor drive arrangement, by means of which the conveyor bottom along the floor construction and the side walls from the top on the conveyor floor deflection device to the bottom is movable, wherein the conveyor bottom provided on both sides in on the side walls Guided tours.

By guiding both sides of the conveyor floor in provided on the side walls guides can be prevented in a simple manner or at least significantly reduced the risk that arranged on the conveyor floor conveyed enters between the conveyor bottom and the side walls provided column or passes through these gaps. In particular, the two-sided guiding of the conveying floor in guides provided on the side walls makes it possible to seal the conveying floor with respect to the side walls and / or the guides.

According to an advantageous embodiment, the guides are formed by provided in the opposite sides of the side walls grooves, in which the conveyor bottom, in particular laterally engages. This is relatively easy to implement and therefore cost.

Preferably, the conveyor floor is movable by means of the drive arrangement along the floor construction and the side walls not only from the top over the deflecting device to the bottom, but also back.

As in the commercial vehicle according to the EP 2 332 773 A1 the conveyor belt rests on support cables, occur in the area of the support points surveys in the conveyor belt. Such surveys have been found to be detrimental if, for example, cargo on pallets on the conveyor belt should be parked instead of bulk material, as can be affected by the surveys, the stability of the pallets and thus the cargo. According to a preferred embodiment, the conveyor floor is therefore at least partially slidably on the floor construction. In particular, the floor construction on its side facing the conveyor floor on a flat support surface on which the conveyor bottom rests at least partially lubricious. As a result, elevations in the running on the floor construction area of the floor conveyor can be avoided.

The conveyor floor is formed for example by a conveyor belt, which is particularly flexible. The conveyor belt consists for example of plastic, of rubber or of another elastomeric material and is advantageously reinforced by fibers and / or fabric and / or metal wires. In particular, the conveyor belt is in one piece. The disadvantage, however, is that such a conveyor belt must always be completely replaced after damage. According to a further development, the conveyor floor comprises a plurality of strips, in particular aligned transversely to their direction of movement, which are preferably designed as rigid or substantially rigid bodies. If some of these strips are damaged, they can be replaced without having to replace the entire conveyor floor. Furthermore, by adding or removing strips, the length of the conveyor floor can be varied. This can only be realized to a limited extent in the case of a conveyor belt since, after shortening the conveyor belt, lengthening it is only possible with great effort or even not at all.

In particular, the strips are designed as equal parts. Thus, the strips can be made particularly inexpensive. Also, equal parts facilitate storage. Furthermore, identical parts simplify the assembly of the conveyor floor.

Advantageously, the strips are hinged together. Thus, the deflection of the conveyor floor is facilitated on the conveyor floor deflection device. According to one embodiment, the strips to each have a recess and a projection, so that in adjacent strips of the projection of one of the strips engages in the recess of the other strip hinged. This embodiment has the particular advantage that the strips for mounting the conveyor floor can be easily assembled without additional joints or hinges for the joint function are required. For example, the projections each comprise an outwardly curved cylindrical surface, the recesses each comprising an inwardly curved cylindrical surface which preferably has the same or approximately the same curvature as the outwardly curved cylindrical surface. The recess and the projection of each strip are provided in particular on opposite sides of the strip in the direction of movement of the conveying floor.

The formation of the strips as a rigid or substantially rigid body makes it possible, in particular, to guide the conveyor floor at a distance from the floor construction in the side walls. In this way, the friction of the conveyor floor can be avoided or at least reduced to the floor construction, so that the conveyor floor is particularly smoothly movable. Furthermore, it is possible to arrange on the floor construction under tension standing ropes on which rests the conveyor floor. Unlike the EP 2 332 773 A1 It is possible due to the rigid formation of the strips to avoid the formation of surveys at the support points. Preferably, the conveyor floor with the strips but at least partially slidably on the floor construction. This is particularly useful at higher loads, otherwise the bottom of the conveyor could be pressed too hard. The friction between the conveyor floor and floor construction can be kept relatively low in this case by a suitable choice of material for the strips.

The strips can consist of different materials. For example, the strips made of plastic or metal or a combination of these materials. The metal is e.g. Aluminum or steel. Preferably, the strips each have a core surrounded by a first material of a second material, wherein the first material advantageously differs from the second material. The strips are thus realized in particular in hybrid construction. The first material is preferably lubricious. As a result, the friction between the conveyor bottom and the bottom construction and / or between the strips can be kept relatively low. In particular, the first material is plastic. Preferably, the second material is stronger than the first material. Thus, the strips can be given a high stability, without having to pay attention to its sliding properties in the choice of material for the core. The second material is preferably metal, in particular aluminum or steel.

The strips can be firmly attached to each other. Preferably, however, the strips are merely inserted into one another and / or placed against one another. According to a development of the conveyor floor, in particular along its direction of movement, under tension, preferably under compressive stress. In particular, the strips are stretched against each other. For example, the bars arranged at the two ends of the conveyor floor are tensioned against one another with the interposition of the other strips. By clamping can be ensured in particular that the strips form a coherent association, namely the conveyor bottom, preferably without strips can emerge from the dressing, especially if they are merely nested and / or placed against each other.

The conveyor floor deflection device preferably comprises a rounded deflecting body, on which the conveyor floor is deflected or guided around from the upper side to the lower side of the floor construction. By the rounded Deflection body, the friction between the conveyor bottom and the conveyor floor deflection device can be reduced. Preferably, the conveyor floor deflection device comprises a guide roller, on which the conveyor floor is deflected or guided around from the top to the bottom of the floor construction. The deflecting roller is preferably rotatably mounted on the vehicle body about a deflecting roller rotational axis extending transversely to the direction of movement of the conveying floor. The deflection roller preferably forms the rounded deflecting body. By the guide roller, the friction between the conveyor bottom and the conveyor floor deflection device is further reduced. The conveyor floor deflection device advantageously comprises a deflecting jacket which partially surrounds the deflecting roller, wherein the conveying floor runs and / or is guided between the deflecting jacket and the deflecting roller. The deflecting jacket is preferably formed as a dimensionally stable body. Due to the deflecting jacket, for example, a bulging of the conveying floor on the conveyor floor deflection device can be avoided. Furthermore, the deflection jacket serves, for example, as protection for an operator, so that they can not come into contact with moving parts on the conveyor floor deflection device. Preferably, however, by the Umlenkmantel a leaching of strips from the conveyor bottom during deflection at the conveyor floor deflection device can be avoided, especially if the conveyor floor is under compressive stress and / or if the strips are merely nested or abutting. In this sense, the deflecting preferably forms a safeguard against leaching of bars during the deflection of the conveyor floor on the conveyor floor deflection device. In particular, the deflecting jacket forms a boundary or installation, preferably a radial boundary or installation for the conveyor floor and / or the strips. Thus, during the deflection of the conveyor bottom deflection device from the conveyor bottom radially outwardly pressing strips can be kept in the conveyor bottom. The inside of the Umlenkmantels facing the conveyor bottom and / or the deflection and / or the guide roller is preferably formed curved and forms in particular a curved inwardly cylindrical surface. Advantageously, the inner side of the Umlenkmantels facing the conveyor bottom and / or the deflecting body and / or the guide roller extends concentrically to the curved lateral surface of the deflecting body and / or the guide roller.

At the conveyor floor deflection device, the curvature of the conveyor floor must not be too large, especially if it comprises the strips. Otherwise, there is a risk that strips will be damaged, jammed and / or come out or that the conveyor floor kinks, e.g. if the conveyor floor is designed as a conveyor belt. For this reason, it is advantageous that the conveyor floor is deflected or guided around with a relatively large radius by means of the conveyor floor deflection device. However, due to the design, this may mean that the conveyor floor beneath the floor construction has an undesirably large distance from it. According to a further development, the utility vehicle therefore comprises a guide roller provided on the underside of the floor construction and offset relative to the guide roller in the direction of the front end of the floor construction, by means of which the conveyor floor emerging from the conveyor floor deflection device on the underside of the floor construction is raised in the direction of the floor construction. This makes it possible to bring the conveyor floor below the floor construction at a small distance to this.

According to one embodiment, the vehicle body comprises lateral guides in which the conveyor floor is guided and which extend over the entire or almost the entire movement path of the conveyor floor. The conveyor floor is thus feasible on both sides in the lateral guides along its entire or almost along its entire movement path. This is particularly advantageous when the conveyor floor is under compressive stress. For example, by means of the lateral guides a local bulging of the conveyor floor and / or a detachment of strips from the conveyor floor can be avoided. Above the floor construction, these lateral guides are formed, in particular, by the guides provided on the side walls, which in this case can also be referred to as upper side guides.

Below the floor construction, these lateral guides are preferably formed by lower side guides, e.g. are provided on the side walls or other lateral components of the vehicle body. In the area of the conveyor floor deflection device, the lateral guides can be omitted, in particular if this has the deflecting jacket. Alternatively, however, the conveyor floor deflection device may also comprise guides which form the lateral guides in the region of the conveyor floor deflection device. These guides can also be referred to as rear side guides.

According to one embodiment, the drive arrangement comprises a traction means arrangement, which in particular is connected to an end of the conveying floor provided on the underside and to an end of the conveying floor provided on the upper side, and to a traction mechanism arrangement deflecting device arranged on the floor construction, by means of which the traction means arrangement of FIG the bottom of the floor construction is deflected or guided around to the top of the floor construction. The Zugmittelanordnungs- The deflection device is preferably arranged offset relative to the conveyor floor deflection device in the direction of the front end of the floor construction. In particular, the Zugmittelanordnungs deflection device is arranged on the vehicle body and / or on the floor construction. Preferably, the Zugmittelanordnungs-deflecting device is arranged at a front end or end portion of the floor construction. In particular, the conveyor floor can be pulled by means of the traction mechanism arrangements. A pulling of the conveyor floor is advantageous because when pressing the conveyor floor there is a risk that the conveyor floor bulges during movement and / or jammed. In particular, a first end of the Zugmittelanordnung with the provided at the bottom end of the conveyor floor is in communication, wherein a second end of the Zugmittelanordnung with the provided at the top end of the conveyor floor is in communication.

The traction means arrangement preferably comprises one or at least one traction means, which in particular communicates with the end of the conveying floor provided on the underside and with the end of the conveying floor provided on the upper side. Preferably, a first end of the traction means is connected to the provided at the bottom end of the conveyor floor in connection, wherein a second end of the traction means is in communication with the provided at the top end of the conveyor floor. Advantageously, however, the traction means arrangement comprises a plurality, preferably two or at least two traction means which are in particular in each case in communication with the end of the conveying floor provided on the underside and with the end of the conveying floor provided at the top. Preferably, a first end of each traction means with the provided at the bottom end of the conveying floor in connection, wherein a second end of each traction means is in communication with the provided at the top of the end of the conveyor base. Advantageously, the traction means extend parallel to each other. The use of only one traction device could cause the problem that minor adjustment errors, which can occur both during assembly and in normal operation, can lead to jamming of the conveyor floor.

The Zugmittelanordnungs deflection device preferably comprises one or at least one traction means deflection device, at which the, which is or at least one or the traction means from the bottom of the floor construction to the top of the floor construction deflected or led around or are. The traction device deflection device is e.g. designed as a role, disc or gear. In particular, the traction means deflection device is mounted rotatably about a traction means deflection axis of rotation on the vehicle body, which preferably extends transversely to the direction of movement of the conveying floor. Advantageously, however, the Zugmittelanordnungs deflection device comprises a plurality, in particular two or at least two traction means deflection devices, on each of which one of the traction means is deflected or guided from the bottom of the floor construction to the top of the floor construction. The traction means deflection means are e.g. designed as rollers, discs or gears. In particular, the traction means deflection devices are each mounted rotatably about a traction means-deflection axis of rotation on the vehicle body, which preferably runs transversely to the direction of movement of the conveying floor.

According to a further development, the drive arrangement has a pull bar provided on the upper side and a draw bar provided on the lower side, wherein the pull means arrangement is connected to the feed floor with the intermediary of the draw bars. Advantageously, the drawbars thus form connection elements, by means of which the traction means assembly is in communication with the conveyor floor. The conveyor floor is preferably clamped between the drawbars, in particular when the conveyor floor comprises the strips. This has the consequence that the strips are pressed against each other. By clamping can be ensured in particular that the strips form a coherent association, namely the conveyor bottom, preferably without strips can emerge from the association, especially if they are merely nested and / or placed against each other. Alternatively, it is possible to dispense with the clamping. In this case, the strips are preferably like chain links of a chain captive connected. However, this alternative is associated with the disadvantage that a greater effort is required for the assembly of the conveyor floor and for the replacement, addition and removal of strips.

According to a further development, the drive arrangement comprises one or at least one drive, by means of which the Zugmittelanordnungs deflection device is drivable, which is preferably frictionally and / or positively connected to the traction means arrangement in connection. If there are several, in particular two or at least two traction means deflection devices, the drive arrangement preferably comprises several, in particular two or at least two drives, by means of which in particular one of the traction means deflection devices can be driven. Alternatively, the traction means deflecting means can also be driven by a common drive.

The traction mechanism arrangement comprises, for example, one or at least one belt as traction means, and the traction mechanism arrangement Deflection device includes, for example, one or at least one pulley as traction means deflection device, with which the belt is frictionally engaged. Alternatively, the traction means arrangement comprises, for example, one or at least one chain as traction means, and the traction mechanism arrangement deflecting device comprises, for example, one or at least one toothed wheel as traction means deflecting device, which engages positively in the chain.

Advantageously, however, the traction means arrangement comprises a plurality, preferably two or at least two, belts as traction means, and the traction device arrangement deflection device advantageously comprises a plurality, preferably two or at least two, pulleys as traction means deflection means, which are frictionally engaged with the belts. Alternatively, the Zugmittelanordnung preferably comprises a plurality, preferably two or at least two chains as traction means, and the Zugmittelanordnungs deflection device preferably comprises a plurality, preferably two or at least two gears as Zugmittel-deflecting means which engage positively in the chains.
