    Description "SADDLE-LOADING TRAILER" [0001] The invention relates to a semitrailer-type trailer according to the preamble of claim 1.
    Various semi-trailer trailers are known from the prior art. In principle, there is the problem that the machines to be transported on such semi-trailer low-load trailers, in particular construction machines or agricultural machines, have increasingly larger dimensions over time. A transport on roads is often only possible if some conditions can be met, often even for the transport of certain goods own routes are provided or at least additionally road construction facilities must be changed (for example, dismantling of traffic lights or the like) to ever to realize the transport. From DE 299 09 103 U1, for example, a semi-trailer trailer is known in which an adaptation to a limited track width is provided.
    The object of the invention is to provide a semi-trailer trailer, which allows a reduction in transport costs.
    The object is achieved on the basis of a semi-trailer trailer of the type mentioned, by the characterizing features of claim 1.
    The measures mentioned in the dependent claims advantageous embodiments and modifications of the invention are possible.
    The semi-trailer according to the invention comprises a loading area, wherein it is designed to lower an area of the loading area as a lowbed bridge. The lowered loading area allows, among other things, the transport of goods, in particular of high-height machines. Basically, the semi-trailer trailer is adapted to be coupled to a tractor, for which purpose a coupling device is provided. The semi-trailer also includes a chassis.
    Accordingly, the semi-trailer trailer according to the invention is characterized in that the Tiefladeebrücke comprise at least a first and a second bridge part, which in turn pivotally, for. connected by a joint. Basically, these two bridge parts can thus be arranged at an angle to each other, wherein the angle, which include both, is variable. The first bridge part can be lowered via a first lowering device, so that a corresponding Tiefladeebrücke first arises in this area. Simultaneously with this lowering movement but also the second bridge part is moved with and thus lowered. By arranging the two bridge parts to one another, the angle, the first and second bridge part include, can be changed. By this measure, initially the flexibility can be increased because depending on the application, a corresponding Tieflade bridge can be formed, if necessary. In addition, the two lowered bridge parts can be arranged offset from one another or pivoted, so that at least one of the two parts can be lowered particularly deep.
    The freedom of movement of the second bridge part is limited by a stop. Due to the fact that the second bridge part is at least partially taken along by the first bridge part, but both are not to be displaced to the same level and in particular not in the same orientation, a substantially simple but nevertheless stable variant is to fix the end position of the second bridge part, to let them drive against a stop as a mechanical obstacle or as a mechanical constraint. In addition, costs can be saved, since in principle adjusting means such as a hydraulic cylinder can be saved, which would not only be provided for moving the bridge part, but would also have to hold it in the corresponding holding position. This arrangement of the two bridge parts also offers the Possibility to transport this. To park well diagonally, especially to arrange a vehicle in a slightly tilted way on the loading area. Advantageously, thus the support load can be better distributed, as would be the case, for example, in a suitably trained and completely horizontally running Tiefladeebrücke because the focus is shifted to the lowest lying cargo area. In addition, such a conventional and already known from the prior art Tiefladebrücke has the disadvantage that they apply special load requirements and transport costs can thus be many times higher, because the thus required, conventional semi-trailer trailers are also correspondingly expensive.
    In the advantageous embodiment of the invention, a second lowering device for lowering the second bridge part may be provided. By this measure, first a further flatbed surface can be formed. The required transport height is also reduced overall. In addition, this makes it possible that the second bridge part can be lowered in horizontal alignment. The flexibility of the semi-trailer semi-trailer is thus adapted to different requirements different goods and especially different vehicles to be transported.
    Accordingly, in an advantageous embodiment of the invention, the second lowering device is adapted to stop the lowering movement when the second bridge member abuts the stop. It is also conceivable that the lowering movement is then terminated when the second bridge part is oriented horizontally or runs parallel to the rest of the loading area outside the Tiefladebrücke, namely preferably lowered to the rest of the loading area. As a result, the mechanical construction is simplified as a whole, and it can also be saved costs, because additional hydraulic cylinders or other support devices for supporting the corresponding bridge part can be saved. Thus, for example, in the present case, four supporting devices, for example hydraulic cylinders, that is two for each lowering device, are sufficient. According to the invention, two support devices can already be saved per lowering device, for example, because a coupling to the pivotable connection of the two bridge parts is provided, so that they can also be moved together mechanically.
    In a particularly advantageous manner, in a variant of the invention, the flatbed bridge or the first lowering device can be configured so that the first bridge part forms a ramp rising in the direction of the stop in the lowered state. If, for example, a vehicle is transported on a semi-trailer trailer according to this embodiment variant, it can be inserted with a wheel axle into this recess formed by the first bridge section, while the further axle of the vehicle to be transported is mounted at a higher level in the region of the second bridge section. Thus, a different weight distribution is provided than with a fully horizontally extending Tiefladeebrücke, i. the center of gravity of the object to be transported or of the vehicle to be transported is displaced in the direction of this depression located in the area of the first bridge part, while the area in the second bridge part is relieved. This also results in other, lower loading requirements for the semi-trailer, so that overall costs can be saved. Due to the inclination of the vehicle and the overall transport height can be reduced.
    Just when a corresponding Satteltiefladeanhänger particular or even primarily used for vehicle transport, a Radmulde may be provided in the region of the first bridge part. Such a wheel well allows stable storage of the vehicle during transport, just because the center of gravity is shifted in the direction of the wheel well. The transport height can thus be reduced once again.
    As lowering devices in particular hydraulic cylinders can be provided. The fact that hydraulic cylinders work with basically incompressible fluids, they allow a precise positioning process even at high load.
    As a drive for corresponding hydraulic cylinder or for the lowering device, in particular, a rotary shaft may be provided which is coupled, for example, to the towing vehicle. The actual drive motor for the lowering device must therefore not be integrated in the semi-trailer. In addition, a drive for all lowering devices or hydraulic cylinders is advantageously sufficient. The coupling is purely mechanical and is only a simple implementation to the towing vehicle necessary. Overall, these measures in turn can be saved costs, since the semi-trailer can get along without additional motor for the lowering devices.
    First and second bridge part can be in embodiments of the invention in the direction of travel in an aspect ratio of 2: 1. Often, the first bridge part can be made shorter, so that this overall already forms the wheel well and the vehicle projects far into the second bridge part. When forming such a relatively narrow wheel well in the region of the first bridge part, the wheel can be stored accordingly with little play. This allows for a higher degree of stability for transport.
    Moreover, it is possible that in one embodiment of the invention, at least one narrow axis is provided so that even when maneuvering a small track width is sufficient. Such a narrow axis can be provided, for example, at the first or second position in the front of the chassis in the direction of travel. Overall, this makes the semi-trailer or the vehicle compact and allows driving at a lower track width. When a part of the loading area, in particular a bridge part, is lowered, this part can be arranged laterally, usually outwardly, offset from the tires arranged on a narrow axis and lowered there, so that the tires are not in the way of the lowering movement and also very deep Reductions are possible.
    A particularly high degree of flexibility can be achieved that the flexibility of the Tiefladebrücke is also increased again. For example, parts of the Tiefladebrücke or the entire Tiefladeebrücke may be formed telescopically, i. they can be shortened or extended in terms of their length in the direction of travel. Thus, an adaptation to goods to be transported, especially on vehicles allows. The corresponding semi-trailer can be used versatile thus. In particular, a tripartite division can be provided for this purpose, namely a division into two outer supports and a drive train in vehicles, the outer supports are used to support the tires on the respective sides of the vehicle, while the drive train is usually passed through in the middle.
    Basically, there is no limitation that such an embodiment of the invention would be limited to certain coupling devices. It is quite possible, for example, saddle gooseneck clutches or couplings for a drawbar.
    Embodiment
    Embodiments of the invention are illustrated in the drawings and are explained in more detail below, giving further details and advantages. 1 shows a schematic representation of a semi-trailer trailer according to the invention, [0021] FIG. 2 shows a schematic plan view from above on the telescopic semi-trailer trailer from FIG. 1, and [0022] FIG. 3 shows a schematic representation of one Satteltiefladeanhängers according to the invention, in which both bridge parts are each formed in one piece.
    Figure 1 shows a semi-trailer trailer 1 with a loading area 2. For coupling to a towing vehicle, a gooseneck 3 is provided. In addition, the semi-trailer 1 comprises a Tiefladebrücke 4, which can form part of the bed 2 and between the chassis 5 and the coupling device (gooseneck) 3 is arranged. The Tiefladebrücke 4 is divided into a first bridge part I and a second bridge part II, which are pivotally connected to each other via a hinge 6. In addition, the first bridge part I is supported by a hydraulic cylinder 7, while the second bridge part II is supported by a hydraulic cylinder 8. Both ensure that the first bridge part I and second bridge part II from the higher level 9, on which the rest of the loading area 2 is located, can be lowered. However, the second bridge part II can only be lowered to the extent that it reaches the area of the stop 10 or abuts the stop 10. The second hydraulic cylinder 8 is then turned off as soon as the stop 10 is reached.
    The first bridge part I is also divided into two areas, which are also connected to each other via a hinge 11, so that the first bridge part I can serve a trough for parking a wheel 12 of a vehicle 13. Optionally, the first bridge part I can also be designed in one piece and form a sloping ramp correspondingly continuously in the lowered state. At the gooseneck 3 and the actual clutch 14 is mounted for coupling to the towing vehicle.
    Figure 2 shows the semi-trailer trailer 1 of Figure 1 with the loading area 2 and the gooseneck 3. Between these two areas is the Tieflade bridge 4, which is composed of the two sections, namely the first bridge part I and the second bridge part II. Both bridge parts I and II are pivotally connected to each other via a hinge 6. In addition, these two bridge parts I and II are formed telescopic. Both bridge parts therefore each form a loading web, each extending in the direction of travel on both sides of the trailer 1, so-called outer support 20, 21. In the middle between two webs runs, also telescopic, the drive train 22. A transportable vehicle can thus on the outer supports 20, 21 are parked with the tires. As needed, e.g. Depending on the vehicle length, the Tieflade bridge 4 can thus be shortened or extended.
    Common to all embodiments of the invention is that the Tiefladeebrücke comprises at least a first and a second bridge part, which are pivotally connected to each other, wherein the first lowering device provided for lowering the first bridge part and wherein a stopper is provided, which is arranged so that it can cooperate with the second bridge part in its lowering movement in order to limit this lowering movement. In this way, transport costs can be significantly reduced. The wider the Tieflade bridge is designed the higher are usually the loads that are to be transported with such a device. In conventional prior art semi-trailer trailers, the cost would typically increase exponentially. Exemplary embodiments of the invention advantageously offer the possibility of transporting heavy loads with high overall heights, such as excavators, bulldozers, crawler loaders, wheel loaders, dumpers or other construction machines, within a permanent-use permit. In addition, however, it is also possible to remain within the usual dimensions for teaching trips or when transporting smaller machines outside of individual approval. Conventional expensive Tiefbett low loaders according to the prior art can be avoided. For example, in embodiments of the invention, machines or loads up to 60 t, with a maximum width of 3 m and a maximum height of 4 m, can be transported within the permanent approval. In addition, environmental emissions can also be reduced.
    Figure 3 shows a semi-trailer trailer 1a, the first bridge portion la, in contrast to FIG. 1 is formed integrally. The bridge parts la and II can thus be lowered in this embodiment of FIG. 3 on the drive cylinder 7, 8 with respect to the level of the loading area 2 (dashed line: not lowered). The cylinder 7 is housed in the side piece of the gooseneck 3 and engages a stop 23 of the bridge part la. Also in this case, the lowering of the bridge part II takes place until it comes into contact with the stopper 10. The bridge part la can continue to drive down because it is connected via the joint 6 with the bridge part II. Between the gooseneck 3 and the joint 6 thus forms a triangular area. The support area of the bridge part II may be laterally offset from the tire 5, which for this reason on a
    Narrow axis are connected.
    In addition, embodiments of the invention can be supplemented separately with other technical features, such as with a hydraulically sprung suspension to allow better road holding and better cushioning during transport.
    In addition, a digger trough can be provided for improved housing.
    Further, hydraulic ramps may be provided, which are optionally also designed to be removable with a quick-change coupling.
    - Hydraulic ramps can thus be automated in an advantageous manner, are also used for heavy ramps.
    - To not limit the ground clearance of construction machinery, the frame can be lowered to the gooseneck. The gooseneck, in turn, may also be provided with outer supports for increasing the support load, wherein the outer support may also be designed to be lowerable via hydraulic receptacles.
    To secure the charge can advantageously be a positive connection between the trailer or the loading area and the charge are produced.
    Further, to secure the vehicles to be transported raster rails may be provided.
    For tools, a separate holding device may be provided.
    When maneuvering, it may be advantageous to use a hydraulic forced steering, which can optionally be controlled by a remote control.
    In general, various hydraulic functions on the low loader may optionally be controlled manually, but advantageously also with remote control.
    - The gooseneck can be configured in various ways, for example, be provided with folding Alubordwänden or optionally with cross members at the rear end.
    The support at the rear of the tractor can be done hydraulically.
