Description

The present invention relates to a tipping trailer with thermal insulation for a tipper vehicle, comprising an inner floor panel and at least one inner side wall, which is connected to the inner floor panel and extends substantially perpendicularly upwards thereof, the inner floor panel and the at least one inner side wall, possibly together with other side walls, delimit a loading area of the tipping trailer, an outer floor covering and at least one outer wall covering, which are each formed by corresponding panels and delimit the tipping trailer on the outside thereof, and between the inner floor plate and the floor External cladding and heat insulation elements arranged between the at least one inner side wall and the at least one wall outer cladding.

Recently there has been an increased demand for such generic vehicles with thermally insulated tipping trailers, since new regulations, for example in the field of road construction, make it necessary to only transport bitumen in vehicles to road construction sites, the strict requirements for the thermal insulation of their loading areas are enough. These requirements particularly require compliance with a defined weighted heat transport coefficient for the tipping trailer of such vehicles, whereby it must be taken into account that some sections of a tipping trailer are less thermally insulated due to their design than others, for example fixed side walls of the loading area compared to swiveling or swinging side walls .

Since appropriate measures for thermal insulation always mean an increased material expenditure, which is consequently reflected in the weight and the manufacturing costs of such a tipping trailer, various attempts have been made to meet the above-mentioned legal requirements just as closely as possible, i.e. as close as possible to the weighted heat transport required. To get coefficients without falling below them. For this purpose, custom-made and dimensioned panels were glued from the outside to the floor and the side walls of the loading area, that is to say the front wall, the rear wall and the two side walls, in known generic vehicles.

However, this type of mounting of insulation panels is very complex because, on the one hand, a large number of individually adapted components are necessary and, on the other hand, the fastening of the panels themselves is labor-intensive and prone to errors. It is therefore the object of the present invention to provide a generic tipping trailer which is distinguished by its simplified construction while maintaining the required thermal insulation properties and which can be produced in particular in a simplified and cost-reduced process.

To achieve this object, in a tipping trailer according to the invention, on at least one side of the inner floor plate there is a terminating edge which extends vertically beyond the floor outer lining and which has a plurality of openings at the level of the floor outer lining, and there is also at least one End strip is provided, which is attached to attachment points which are assigned to the end edge, and which on the one hand holds at least one panel of the one or more wall claddings and on the other hand has a plurality of projections which extend through the openings in the end edge by at least to hold a panel of the floor cladding.

By providing the end strip at the attachment points on the horizontal outer sides of the end edge and at the same time passing the projections through the openings, the end strip can simultaneously hold panels from a wall outer cladding and the floor outer cladding, which makes it much easier to assemble these claddings because after positioning the heat insulation elements and the corresponding panels, the end strip can simply be plugged onto the end edge by passing the projections through the openings and then fastened, in particular screwed, to the attachment points. Furthermore, it has been shown that such a construction is particularly insensitive to stresses caused by thermal expansion of the individual components, since the mounting of the individual panels always has sufficient play, without however affecting the strength of the connection.

It goes without saying that such an end strip can be provided on all edges of the bottom plate of the tipping trailer with permanently installed side walls, for example in the case of a two-way tipper on the front side and the side into which no tipping, and in the case of a pure rear tipper on the Front and both side walls. On the sides to which a tipping is provided, a somewhat differently constructed wall construction with corresponding fastening of the panels is therefore to be provided, as well as an additional strip which only holds the panels of the floor outer cladding, since here there is a common fixed bracket the outer wall cladding of the side or rear wall and the floor outer cladding cannot be provided.

Although the end edge can be provided at different positions on the corresponding outer side (s) of the tipping trailer, the end edge is preferably arranged essentially in vertical extension with the inner side wall, for example for simplified assembly of the heat insulation elements.

Alternatively or additionally, it can be advantageous for optimal force absorption to provide the attachment points on angle elements which are firmly connected to the end edge, for example welded or screwed. Of course, the attachment points could, however, also be provided directly on the end edge, but this would in some circumstances lead to a less good holding of the end strip.

To reduce the weight of the tipping trailer, it can also be advantageous if the panels of the floor outer cladding and / or the at least one wall outer cladding are made at least in sections of aluminum. Of course, any other material with sufficient hardness and resistance could also be used, for example a stainless steel.

In order to enable the use of identical parts and thus to save costs in the manufacture of the tipping trailer according to the invention, at least some of the heat insulation elements can be in the form of plates made of heat-insulating material, preferably at least two of the plates having the same dimensions and preferably at most five plates having different dimensions . It turns out that with such a small number of differently dimensioned plates, a large part of the area to be insulated can already be covered, whereby for less accessible or angled positions, a small number of additional separately shaped individual parts can be provided, which are irregular here Shape should not be called plates.

In order to further simplify the assembly of the tipping trailer according to the invention, the panels of the floor outer cladding and / or the at least one wall outer cladding can have a layer structure at least in sections, with a hard outer shell, for example made of metal, in particular aluminum, and one serving as a heat insulation element heat-insulating material on the inside. In this way, the heat insulation and the outer shell can be attached in the same assembly step, it being understood that additional heat insulation elements can be provided, that is to say an overall multi-layer insulation, which is partly firmly assigned to the panels and partly, for example, from the panels described above predetermined dimensions can exist, which can then be stacked in the thickness direction of the corresponding wall or floor.

Although a variety of materials can be suitable for the heat insulation elements, it has been found that excellent properties in terms of heat insulation, weight, cost and processing result if the heat insulation elements comprise pures.

In a conventional design of tipping trailers, in order to stabilize their load-bearing floor in the area of their inner floor plate, they comprise at least one cross member which extends downwards in the longitudinal direction of the tipping trailer and from the inner floor plate. Such cross members are usually designed as hollow profiles and welded to the corresponding floor in order to give it increased torsional rigidity.

In order to achieve adequate thermal insulation in the area of this or these cross members and to suppress thermal bridges, in the tipping trailer according to the invention, this type of construction in the area of the cross member or members can essentially follow the floor outer paneling of the shape of the corresponding cross member, with cross member profile panels being provided for this purpose are. These cross member profile panels can have a hat-shaped cross section and can essentially be placed on the cross member (s).

To fasten the cross-member profile panel or panels, angled rails can also be provided on the tipping trailer according to the invention, by means of which the cross-member profile panels are screwed to the cross member or members, for which purpose the cross member profile panels are provided with suitable through-holes, in particular elongated holes. This also ensures that the individual panels are held with a certain amount of play, so that thermal expansion of the individual components can also be absorbed here without dangerous voltages being generated.

Furthermore, it is advisable to design the angle rails just mentioned in such a way that they extend laterally in such a way that they also hold further panels of the floor outer cladding in addition to the cross member profile panels. In this way, one is also in the area of the cross member Simplified installation is achieved in a similar manner to that in the area of the end strips, since additional panels can be held by installing a single component.

Finally, in this design, to further reinforce the fastening of the panels of the floor outer cladding by means of the angle rails and the cross member profile panels, the further panels of the floor outer cladding can have an undercut, behind which a section of the cross member profile panels lies, so that the further panels the floor outer cladding is clamped between the corresponding cross member profile panel and the angle rail.

According to a second aspect, the present invention relates to a vehicle with a tipping trailer according to the invention, which further comprises a tipping device which comprises tipping the tipping trailer to one, two or three sides.
