Description

The invention relates to a utility vehicle according to the preamble of claim 1 and to a transport system according to the preamble of claim 12.

Commercial vehicles, such as semi-trailers have been known for some time and are used for transporting goods of all kinds. Here, the semi-trailer are usually moved on the road; However, there is often the need to load these commercial vehicles on the train.

For this purpose, the semitrailers are transported by train with so-called pocket wagons. The pocket wagons are designed to accommodate semi-trailers, typically one semi-trailer per pocket wagon, with the semi-trailers being secured in the pocket wagon by a kingpin lock, similar to a towing vehicle. For the time being there are for this purpose about 9 to 11 pocket wagon variants, which are to cover the entire semitrailer range. For some time, however, semitrailers are desired, which have a greater length than previous standard semi-trailer and are 1.3 meters longer than standard semi-trailer. These so-called mega-vehicles are designed lower in the frame and chassis area, namely in terms of their side members, their chassis and their tires as a standard semi-trailer to represent a maximum interior height when complying with the legal total height allowed. For this reason, these so-called mega-vehicles, i. Vehicles extended by 1.3 meters will not be loaded into any pocket wagon, as this would result in a trauma to the pocket wagon at the rear.

The invention is based on the object of providing a commercial vehicle, in particular a semitrailer, while avoiding the aforementioned disadvantages, which can be loaded into a conventional pocket wagon in a simple and cost-effective manner without envelope damage, and also to specify a transport system with such a utility vehicle.

This object is achieved by a commercial vehicle according to claim 1 and by a transport system according to claim 12.

In particular, the object is achieved by a commercial vehicle, in particular a track-loading semi-trailer, with a frame which has at least one, in particular at least two, longitudinal members and a rear cross member terminating the frame to the rear, wherein the / the longitudinal members each have / have a Heckeinzug, wherein a lower limit of / the side member in, in the forward direction of travel of the commercial vehicle, the rear portion of the frame is stepped and / or obliquely upwards.

An essential point of the invention is that the or the side members of the commercial vehicle, which would lead to an expansion of the payload surface of the commercial vehicle to a Hüllraum injury of the bag wagon, be designed so that the or the side members on the upper limit of the pocket of the bag wagon protrude. In this way, a violation of the rear of the baggage cart by an extended commercial vehicle in a simple but very effective manner safely avoided.

The longitudinal members of the commercial vehicle, such as semitrailers, are pulled upwards in the rear area, so that the side members are above the interference contour of the baggage cart during loading. This so-called Heckeinzug can be formed according to the invention stepwise or obliquely or from a combination of stepped and oblique course.

According to a preferred embodiment, a length of the frame minus a length of the rear catch in the range of 5 m to 13.7 m, preferably in the range of 13.6 m ± 0.2 m, wherein the length of the rear catch preferably in the range of 1, 3 m ± 0.2 m. In an extremely advantageous manner, a conventional pocket wagon can be used in this way for a rail transport of the extended mega-vehicle, the commercial vehicle can be adjusted in a conventional manner in the pocket wagon and the extended part of the mega-vehicle rear side on the rear edge of the pocket of the Pocket cart protrudes.

According to a particularly preferred embodiment of the invention is or are at least one, preferably two substantially perpendicular to the rear cross member extending (s) support member (s) attached to the rear cross member of the frame of the commercial vehicle and with respect to the rear cross member parallel pivot.

On the support elements, one or more attachments, such as an underrun protection and / or lighting device (s) and / or license plate devices, such as a motor vehicle license plate, fastened. According to an alternative embodiment of the invention, the support elements can also serve as underrun protection itself, if their ends are in working position, for example with transverse strips, the extend substantially parallel to the rear cross member, are equipped.

According to the invention, the support element (s) can be pivoted from a functional position in which the support element extends substantially vertically downwards into a rest position in which the support element preferably extends substantially vertically upward, and vice versa , Wherein a pivot axis of the support element is arranged on the rear cross member, in particular integrated in this.

According to the invention, two spaced support elements are provided on the rear cross member, which are connected to each other via attachments, such as a strip-shaped underrun protection or lighting device and / or a bar for attaching a lighting device and / or a license plate.

In this way, the underride protection and the lighting and / or license plate devices of the commercial vehicle can be easily pivoted from its functional position to a rest position. The functional position in this case defined by the fact that the underrun protection is in a lowered position, which effectively prevents driving under the utility vehicle and the license plate and lighting of the commercial vehicle are aligned substantially vertically and can be well seen by the road users located behind the utility vehicle. For this purpose, the support element is pivoted in its functional position under the rear catch and fixed there, for example by means of at least one hook.

The rest position of the underrun protection and the lighting and / or license plate devices of the commercial vehicle is defined by the fact that both the underrun protection and the lighting and / or license plate device of the commercial vehicle are folded so far upwards, respectively pivoted that neither the support elements nor the it attached attachments come into spatial conflict with the geometry of the baggage cart, but protrude, starting from the rear cross member adjacent to the pocket of the bag carriage freely over the upper limit of the baggage cart.

According to a particularly preferred embodiment of the invention, the support elements and the attachments attached thereto protrude not only horizontally over the upper boundary of the bag cart, but almost vertically upwards. In this position, the support member is thus in its rest position and with respect to its functional position by 180 ° ± 45 °, preferably ± 25 ° and more preferably ± 10 °, namely upwards, pivoted.

According to an alternative embodiment of the invention, however, the supporting element together with its attachments in its rest position can also be folded into a recess of the frame and / or between the longitudinal members. In this case, the support elements are not pivoted up rear, but to the front above, with a pivot angle in this case in about 90 ° ± 25 °, preferably ± 10 °.

According to the invention, the support element in side view has a substantially L-shaped contour, one, for example, short leg of the "L" for attachment and articulation of the support member to the rear cross member and the other, for example, long legs of the "L" for attachment of Attachments used. The respective dimensioning of the legs of the "L" is variable and depends on the particular requirements. In an extremely advantageous manner, the underrun protection and the lighting and / or license plate device can thus be folded in functional position below the rear-side boundary of the commercial vehicle, so that neither the underrun protection nor the lighting and / or license plate devices behind the rear-side boundary of the commercial vehicle Stand out commercial vehicle, however, be folded in the rest position on the rear boundary of the commercial vehicle and the rear cross member so that the commercial vehicle according to the invention can be loaded easily and without great effort in a pocket van in the case of rail loading and placed in this optimal, without a shell injury of Passenger car is to be feared.

According to a further embodiment of the invention, the utility vehicle has an assistance device, such as a gas spring or a hydraulic device or other suitable for raising and lowering devices on to the support element or via attachments such as strips, interconnected support elements from its functional position in his To move rest position and vice versa and to fix if necessary in its respective end position. The assistance device can be designed to be supportive or fully automatic for manual operation.

Furthermore, the object of the invention is also achieved by a transport system, in particular a truck, which is equipped with a commercial vehicle according to the above statements.
