    专利说明:

    The invention relates to a Hochlastzugöse according to the preamble of claim 1.
    Hochlastzugösen are drawbar eyes, which are used for pulling heavy trailers, for example in the field of agriculture. Here Hochlastzugösen are known, which have a fastened to the trailer bearing housing, wherein a coupling element exhibiting shaft is inserted into the bearing housing and is secured to a side opposite the coupling element with a screwed securing element. By this construction, the shaft can be replaced. The shaft is usually rotationally symmetrical about the central axis, wherein a diameter of the shaft decreases with increasing distance from the coupling element, so that the shaft can be inserted into the bearing housing.
    The disadvantage of this is that in the design of the shaft care must be taken that this is inserted into the bearing housing. Furthermore, the screw which secures the securing element must receive large tensile loads during operation and be correspondingly dimensioned and fastened with a corresponding torque, which makes it difficult to exchange the shank.
    The object of the invention is therefore to provide a Hochlastzugöse of the type mentioned, with which the mentioned disadvantages can be avoided, and which can be better adapted to the designed load in the form.
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that the shape of the shaft can be freely selected by the split bearing housing and can be better matched to the designed load and the particular requirements. For example, the diameter of the shaft may be greatest at the point where the highest bending moments occur. This allows the Hochlastzugöse be made easier and material-saving, with an optimal course of the voltage curves can be achieved in the designed load. Furthermore, the change of the shaft can be facilitated as an opening of the
    Bearing housing is easier than removing the fuse element. When installing or removing the shaft, it is also advantageous that it can be inserted laterally and does not need to be pushed frontally, as this requires less space.
    The subclaims relate to further advantageous embodiments of the invention.
    It is hereby expressly referred to the wording of the claims, whereby the claims at this point are incorporated by reference into the description and are considered to be reproduced verbatim.
    The invention will be described in more detail with reference to the accompanying drawings, in which only a preferred embodiment is shown by way of example. Showing:

    1 to 9 show a preferred embodiment and parts of the preferred embodiment of a Hochlastzugöse 1 for a vehicle trailer, wherein a coupling element 2 exhibiting straight shaft 3 is arranged in a bearing housing 4, on the side facing away from the coupling element 2 of the shaft 3 a securing element 5 of the shaft 3 is supported on the bearing housing 4. A Hochlastzugöse 1 is a towing eye, so a device for coupling a vehicle trailer to a towing vehicle, which is designed for receiving high tensile loads and supporting loads, such as those occurring in agriculture, for example.
    Here, the Hochlastzugöse 1 has a coupling element 2, which is provided for coupling with a counter-coupling element, wherein the counter-coupling element may be attached in particular to a towing vehicle.
    As shown in FIGS. 1, 6 and 7, it can be provided in particular in the preferred embodiment that the coupling element 2 is designed as a ball socket. However, the coupling element can also have other shapes and be designed, for example, as a ring eyelet.
    The shaft 3 may be particularly preferably formed as a forged part.
    The shaft 3 is arranged partly in the bearing housing 4, wherein the bearing housing 4 is preferably designed such that the bearing housing 4 can be fastened to a drawbar of a vehicle trailer. Here, the bearing housing 4 may have a particular planar mounting surface 11, which contacts a drawbar of the vehicle trailer in a fixed state of Hochlastzugöse 1.
    The bearing housing 4 may be particularly preferably formed as a forged part.
    The shank 3 has on a side facing away from the coupling element 2 a securing element 5, which securing element 5 is supported on the bearing housing 4 and thus holds the shaft 3 in the bearing housing.
    It is provided that the bearing housing 4 is formed divided. Here, in particular, the bearing housing 4 may consist of two or more bearing housing parts 8.9, wherein in an assembled state of the bearing housing 4, the shaft 3 is held in the bearing housing 4 by a positive connection, and in a disassembled state of the bearing housing 4, the shaft 3 from the bearing housing 4 is removable. It can be achieved that for removal or insertion of the shaft 3 in or out of the bearing housing 4, the bearing housing 4 can be opened, and the shaft 3 need not be pushed parallel to its longitudinal axis in the bearing housing 4.
    Furthermore, a vehicle trailer comprising a Hochlastzugöse 1 may be provided, wherein the Hochlastzugöse 1 is formed as described above. The vehicle trailer may in particular be an agricultural vehicle trailer. Furthermore, it can be provided that the vehicle trailer has a drawbar, that the bearing housing 4 attached to the drawbar, in particular welded or screwed, and that the mounting surface 11 of the bearing housing 4 contacts the drawbar.
    Preferably, it can be provided, the securing element 5 is supported on an outer side of the bearing housing 4. Here, the shaft 3 can reach through the entire bearing housing 4. In this case, a conventional shaft can be inserted into the bearing housing in an advantageous manner.
    In particular, it may be provided in this case that a recess 12 is formed on the outer side of the bearing housing 4, and that the securing element 5 is arranged in the recess 12.
    Alternatively it can be provided that the bearing housing 4 is closed on the outside of the coupling element 2 outside, and that the securing element 5 is surrounded by the bearing housing 4.
    Particularly preferably, it can be provided that the shaft 3 is formed in one piece. In particular, it can be provided that the securing element 5 is formed on the shaft 3. In this case, a particularly advantageous voltage curve in the shaft 3 can be achieved, since the securing element 5, which receives substantially all the tensile forces, is formed directly on the shaft 3 and the forces can pass well. Furthermore, this can make the Hochlastzugöse 1 platzersparrender because no space for a fuse element 5 with the remaining shaft 4 connecting screw needs to be present.
    Particularly preferably, it can be provided that a first part 6 of the shaft 3 is arranged in a receptacle 7 of the bearing housing 4. The coupling element 2 may in particular be integrally formed on the first part 6 of the shaft 3, wherein the first part 6 may be formed in particular rotationally symmetrical about a longitudinal axis of the first part 6. The longitudinal axis of the shaft 3 may be the longitudinal axis of the first part 6.
    Here, the shaft 3 according to the preferred embodiment of the coupling element 2, the first part 6 and the securing element 5 consist, which together form the one-piece shaft 3.
    Preferably, the first part 6 of the shaft 3 may have at least one contact surface 13, which is in contact with at least one opposite counter-contact surface 14 of the receptacle 7. Here, the at least one contact surface 13 and the at least one mating contact surface 14 may be formed annularly about the longitudinal axis of the shaft 3. According to the preferred embodiment, in each case two contact surface 13 and mating contact surface 14 may be provided.
    Furthermore, it can be provided that the receptacle 7 has a lubricating device, for example comprising a graphite body. The lubricating device can be arranged in particular in the region of the at least one contact surface 13 and lubricate the contact surface 13.
    As shown in FIGS. 1 to 6, as well as FIGS. 8 and 9, it can preferably be provided that the bearing housing 4 has a first bearing housing part 8 and a second bearing housing part 9. Particularly preferably, the first bearing housing part 8 and the second bearing housing part 9 can be substantially the same size. Here, the bearing housing 4 may be particularly simple and robust. In a vehicle trailer here, the first bearing housing part 8 or the second bearing housing part 9 may be attached to the drawbar.
    Preferably, it can be provided that the bearing housing 4 is substantially divided along a first plane, and that a longitudinal axis of the shaft 3 is arranged in the first plane. By way of example, the bearing housing parts 8, 9 can essentially each have a semicylindrical receptacle 7. As a result of this embodiment, the two bearing housing parts 8, 9 can be designed as essentially two semicylindrical shells which hold the shaft 3. Here, a particularly good handling and a stable construction can be achieved. Furthermore, the two bearing housing parts 8,9 can be particularly easily formed as forgings.
    Particularly preferably, it can be provided that the first bearing housing part 8 and the second bearing housing part 9 are connected to each other in a non-destructive detachable manner. In particular, the first bearing housing part 8 and the second bearing housing part 9 can be screwed together. Thereby, a simple and repeatable opening of the bearing housing 4 can be achieved.
    In this case, it may be provided that the first bearing housing part 8 and the second bearing housing part 9 have aligned connecting means receptacles 17, which connecting means receptacles 17 may be provided in particular for receiving screws. A central axis of the connecting means receptacles 17 may be in particular normal to the longitudinal axis of the shaft 3.
    According to the preferred embodiment, the connecting means receptacles 17 of the bearing housing part 8, 9 which can be fastened to the vehicle trailer can have a thread into which the screw 18 engages.
    Alternatively, it can be provided that the connecting means receptacles 17 are formed thread-free. In this case, the screws 18 can pass through the two bearing housing parts 8,9 and engage in a trained in the drawbar thread, the screws 18, the bearing housing parts 8.9 fastened together and to the drawbar. As a result, the number of required connection means can be kept low.
    Furthermore, it can be provided that the first bearing housing part 8 and the second bearing housing part 9 have at least one latching extension 15 and at least one opposite latching projection receptacle 16. In this case, a lateral displacement of the two bearing housing parts 8,9 to each other can be prevented.
    According to the preferred embodiment, four pairs of latching extensions 15 and latching projection receptacles 16 are provided.
    Preferably, it may further be provided that the at least one mating contact surface 14 in an area between two
    Connecting means 17 is arranged. As a result, forces acting on the shaft 3 can be forwarded to the bearing housing 4 at particularly well fastened areas of the bearing housing 4.
    In the preferred embodiment, four connecting means receptacles 17 are provided, which are each formed in half in the first bearing housing part 8 and the second bearing housing part 9. In this case, the four connecting means receptacles 17 are divided into two pairs, each pair having two connecting means receptacles 17, which lead on both sides of the shaft 3 over. In this case, in the pairing of the connecting means receptacles 17, a mating contact surface 14 may be formed.
    Preferably, it may further be provided that the shaft 3 has an anti-rotation extension 10. The anti-rotation extension 10 prevents rotation of the shaft 4 about the longitudinal axis. Here, the anti-rotation projection 10 may be formed in particular in the first part 6, wherein in the receptacle 7, as shown in Fig. 4, a Drehsicherungsnut 19 is formed, in which the anti-rotation extension 10 can engage. Due to the split design of the bearing housing 4 in this case the rotation lock can be designed to be particularly simple and reliable.
    The anti-rotation groove 19 may be formed in particular in both bearing housing parts 8. Here, the shaft 4 can be installed rotated if necessary by 180 °.
    Furthermore, it can be provided that in the receptacle 7, a cable channel is formed. The cable duct can be provided for the passage of electrical cables, it being particularly advantageous here if a cable connection between towing vehicle and vehicle trailer takes place immediately adjacent to the coupling element 2. Due to the split design of the bearing housing 4, the cable channel can be particularly easily milled into the receptacle.
    Furthermore, provision may be made for sensors to be mounted on the shaft 4, for example on the coupling element 2 or on the first part 6 of the shaft 3. These sensors may, for example, comprise strain gauges which measure the tensile and / or bending loads, thereby exceeding the designed load or an impending material failure can be reliably detected. The supply of the cables for the sensors can be done in particular via the cable channel.
