DE202022104544U1 - Final traverse of a commercial vehicle with attached trailer hitch - Google Patents

Abstract

Attachable to the frame (1) of a utility vehicle and carrying a trailer hitch (3), characterized in that the trailer hitch (3) is attached to a longitudinal beam (7) that can be displaced transversely to the end crossbar (2).

Description

The invention relates to a final cross member that can be fastened to the frame of a commercial vehicle and carries a trailer hitch.

Such final trusses are well known, for example from DE 20 2011 052 209 U1 and the DE 601 29 115 T2 .

The trailer hitch is fastened to a longitudinal side of the final crossbar, usually by screwing, for which purpose the trailer hitch has a connection plate that bears against the assigned longitudinal side of the final crossbar.

The disadvantage here, however, is that the trailer hitch is positioned at a fixed distance from the final traverse, resulting in a number of problems.

For example, in the case of trucks with tail lifts or those that are used on construction sites, but also in general, the trailer hitch does not match a trailer drawbar or a truck/trailer combination. The only solution that has been found and implemented so far was the extension of the frame bars of a vehicle frame, to which the final traverse is attached.

Naturally, this is associated with a considerable outlay, in particular in terms of manufacturing technology, which leads to significant increases in costs, which stand in the way of the cost minimization that is always sought.

Apart from that, the functionality of the trailer hitch is also limited, since the horizontal pivoting angle for a trailer hitch held and thus the connected trailer, especially in commercial vehicles whose frame is not correspondingly extended, is significantly smaller than required or desired.

The invention is therefore based on the object of further developing a final cross member of the generic type in such a way that it can be mounted universally on the frame of a commercial vehicle without any adjustment work.

This problem is solved by a final traverse with the features of claim 1.

With the invention, the trailer hitch can now be easily adjusted to the essentially desired distance from the final traverse and fixed in this position.

This means that the area of access to the trailer hitch for coupling a trailer is in any case possible without any hindrance, without requiring changes to the frame or its frame members, as is the case with the prior art described.

For example, the new crossbeam can also be used on trucks with a tail lift or on trucks used on construction sites without changing the frame.

According to an advantageous development of the invention, the longitudinal beam is positively connected to the final cross member, for example by screws or suitable latching means. The final traverse has two traverse sections, between which the longitudinal beam is arranged and which bear against the opposite longitudinal sides of the longitudinal beam.

This is preferably tubular, in particular as a square tube with a front closure plate to which the trailer hitch is attached.

To fasten the respective traverse section, these are provided on the side facing the longitudinal beam with a connecting body which has through-holes which are arranged in the same hole pattern as the through-holes of the longitudinal beam. The longitudinal bar can be moved and locked in accordance with the hole spacing.

The respective connecting body is preferably of angular design in cross-section, with one leg resting on the longitudinal side facing the traverse section and the other section resting on the side of the longitudinal beam which is angled thereto.

For the screw connection of the respective traverse section with the longitudinal beam, the latter has a protruding flange in its cross-sectional extension on the longitudinal side facing the traverse section, which flange is provided with the through-holes mentioned.

In addition to the significantly cheaper completion of the frame with a connected final cross member, the invention also allows a larger horizontal pivoting angle of a connected trailer drawbar. This also results in a significant advantage, in particular a handling advantage over the prior art.

Further advantageous developments of the invention are characterized in the dependent claims.

An embodiment of the invention is described below with reference to the accompanying drawings.

• 2 eine Schlusstraverse gemäß der Erfindung, ebenfalls in einer schaubildlichen Darstellung
• 3 die Schlusstraverse nach 2 in einer Seitenansicht

Show it:

• 1 an assembled closing beam according to the prior art in a perspective view
• 2 a final traverse according to the invention, also in a diagrammatic representation
• 3 the final traverse 2 in a side view
• 4 the final traverse with the trailer hitch in a different position, also in a side view
• 5 the final traverse in a plan view
• 6 a section through the final traverse according to line VI-VI in 4 .

In the 1 shows a prior-art final cross member 2 that is fastened to frame members 4 of a frame 1 of a commercial vehicle and carries a trailer hitch 3 .

The final traverse 2 consists of a tube to which connecting plates 5 are fastened at the end, which are connected to the frame members 4 by screw connections.

In the 2 - 6 a final cross member 2 is shown according to the invention, in which the trailer hitch 3 is attached to a longitudinal beam 7 that can be displaced transversely to the final cross member 2 .

The final traverse 2 consists of two traverse sections 6 between which the longitudinal beam 7 is arranged, with the traverse sections 6 bearing against the opposite longitudinal sides of the longitudinal beam 7 .

To lock the longitudinal strut 7 on the final traverse 2, connecting bodies 9 are fastened to the traverse sections 6 on the face side, in particular cohesively, which in the example are each designed as angles 6 can be seen particularly clearly.

A shorter leg of the connecting body 9 rests on the upper side of the longitudinal beam 7 and is connected to the longitudinal beam 7 by means of screws 12 . The end area of the other leg of the connecting body 9 is fastened by screws 12 to a flange 10 of the longitudinal beam 7 which protrudes beyond the underside of the longitudinal beam 7 in the form of a strip.

To fix the trailer hitch 3 relative to the final cross member 2 in different positions, as in the 3 and 4 are shown, through-holes 11 are provided on the connecting bodies 9 and the longitudinal member 7, through which screws 12 are passed, with the distances between the through-holes 11 and the screws 12 each determining the extent by which the longitudinal member 7 and thus the trailer hitch 3 are opposite the final traverse 2 can be moved and fixed.

Instead of the angular configuration of the connecting body 9, it can also be configured with a U-shaped cross section. Furthermore, the locking of the longitudinal bar 7 on the final cross member 2 can take place via suitable latching means.

In addition, the trailer hitch 3 is attached to a connection plate 8 of the longitudinal beam 7, which closes this front side and is connected to it.
