    The invention relates to a vehicle with lateral lifting device.
    From EP 0 870 727 B1 and EP 2 518 010 B1 various designs of sideloaders are known.
    The sideloaders known from EP 0 870 727 B1 and EP 2 518 010 B1 have the disadvantage that components received on the lifting device can only be lowered below a supporting plane of the vehicle if the components are pushed laterally out of the region of the vehicle ,
    The object of the present invention was to overcome the disadvantages of the prior art and to provide a vehicle which has increased flexibility.
    This object is achieved by a device according to claim 1.
    The vehicle according to the invention is equipped with a lateral lifting device. The vehicle comprises at least a first axle carrier and a second axle carrier, wherein the two axle carriers are coupled to one another by means of a laterally eccentrically arranged connecting construction, and wherein the lifting device is arranged in a free space between the two axle carriers. The lifting device comprises at least a first lifting mast with a first vertically displaceable fork holder receptacle and a second mast with a second vertically displaceable fork holder receptacle. The two masts are controlled so that the fork holder receptacles are synchronously displaced to each other.
    An advantage of the inventive design of the vehicle is that through the formation of two masts the clearance between the two axle beams may have a higher length than in conventional sideloaders. In particular, this allows the clear length of the free space to be chosen so large that the components to be transported are shorter than the clear length of the free space. Thereby, the components to be transported can be lowered even if they are within the width of the vehicle, whereby the loading of the lowest shelf level is facilitated by close to each other built shelves. In addition, a higher load can be absorbed by the two masts. In particular, when the two masts are synchronized with each other, a fork holder can be moved evenly by the two masts.
    Furthermore, it may be expedient if the two masts are horizontally displaceable in the transverse direction of the vehicle. The advantage here is that the component to be transported can be laterally pushed out of the width of the vehicle by this measure and thereby can be stored in a storage rack. In particular, it may be provided that the lifting masts are displaceable between a rest position and an extended position. In the rest position, the support forks of the fork holder are within the width of the vehicle and the masts are moved as close to the connection construction. In the extended position of the masts the support forks of the fork holder are laterally opposite the width of the vehicle and the masts are moved to the connecting structure opposite side of the vehicle.
    Furthermore, it can be provided that the two masts are supported by means of a strut together. The advantage here is that the stability of the lifting device can be improved by this measure, whereby the overall stability of the vehicle can be improved.
    In addition, it can be provided that the first lifting mast has a first guide unit on a first side facing the first axle carrier, and that the second mast is connected to a second one adjacent to the second axle carrier
    Side has a second guide unit. The advantage here is that by this measure, the two masts, which are assembled to the lifting device, can be slidably received in the free space of the vehicle. In particular, this makes it possible to achieve the displacement of the lifting mast between the rest position and the extended position.
    Also advantageous is an expression according to which it can be provided that the two guide units each have at least two horizontally spaced main guide rollers with horizontally oriented rotation axis, which main guide rollers each interact with a guide rail arranged in the axle carriers, wherein the main guide rollers for receiving the on the lifting device acting load and the torque acting on the lifting device are formed, and that the two guide units each have at least one acting in the horizontal longitudinal direction of the vehicle stabilization module, which serves for horizontal positioning of the main guide rollers in the guide rail. In particular, by the stability module can be achieved that the overall rigidity of the vehicle can be increased. This may be necessary especially when the vehicle has a free space with a large clear width and thus the connecting structure has a large length, whereby the basic stability of the vehicle is reduced.
    According to a development, it is possible for the stabilization module to have a stabilization guide roller with a vertically oriented rotation axis, which stabilization guide roller interacts with a stabilization guide rail arranged in the axle carriers. The advantage here is that such a stabilization guide roller on the one hand can absorb high forces and beyond is very wear and maintenance in continuous operation.
    Alternatively, it can be provided that the stabilization module has two sliding elements which cooperate with the stabilization guide rail arranged in the axle carriers. An advantage of such sliding elements is that they are inexpensive and easy to install on the stabilization module.
    In addition, it can be provided that two drive units are formed, which serve for the horizontal displacement of the masts in the transverse direction of the vehicle. The use of two drive units, which are preferably arranged opposite one another on the lifting device, is that the lifting device has an increased torsional rigidity or that both masts can be evenly extended or retracted.
    Furthermore, it can be provided that the drive units each comprise at least one hydraulic cylinder. The advantage here is that hydraulic cylinders are possible low maintenance and simple design and also can muster a sufficient thrust at the highest possible speed.
    According to a particular embodiment, it is possible that a fork holder is formed, which is coupled on a first side with the first fork holder receptacle of the first mast and is coupled on a second side with the second fork holder receptacle of the second mast. The advantage here is that such a trained fork holder, which is coupled to both masts, may have a high overall length and thus may be formed, for example, for receiving a plurality of roll-shaped components to be transported or may be formed for receiving long components to be transported.
    According to an advantageous development, it can be provided that the two lifting masts each have a telescopic running rail system, on each of which the fork holder receptacle is arranged. By this measure, it can be achieved that the two masts can have increased flexibility or increased lift.
    In particular, it may be advantageous if the telescopic rail system of the masts comprises a first pair of rails with two U-shaped single rails, the open ends of the two U-shaped single rails are arranged opposite to each other and wherein the fork holder receptacle is formed on a carriage, which has at least four guide rollers, wherein two guide rollers are guided in pairs in one of the U-shaped formed individual rails and wherein the U-shaped formed individual rails are guided in a second pair of rails slidably. Such a constructed track system can have increased stability, whereby the positioning accuracy of the component to be transported can be improved, especially in the raised position.
    Furthermore, it can be provided that the first axle carrier has a first wheel pair and the second axle carrier has a second wheel pair, with both wheel pairs being steerable. The advantage here is that can be reduced by the possibility of steering both wheel pairs of the turning circle of the vehicle and thus the flexibility of the vehicle can be increased. This may be necessary in particular when using the vehicle in narrow aisles.
    In addition, it can be provided that the connecting structure is arranged on the lateral edge of the axle, so that the vehicle is formed in plan view U-shaped, wherein the two mutually parallel legs of the U-shaped vehicle formed by the axle and the space for Recording the lifting device is formed on the open side of the U-shaped arrangement. The advantage here is that by these measures, the width of the free space can be as large as possible and thus the support forks of the fork can have the greatest possible length.
    Also advantageous is an expression, according to which it can be provided that the connecting structure is telescopic, and thereby a length of the vehicle is variable. In particular, it can be achieved that the length of the vehicle can be adapted to the respective application requirements, in particular to the respective components to be transported or to the space available in the area of application of the vehicle. Such a tele-scoping function of the connection structure can be achieved, for example, by sliding into each other profiles. In addition, for example, a hydraulic cylinder may be provided by means of which the length of the vehicle can be actively adjusted. Of course, in a telescopic connecting structure and the lifting device, for example, in the strut te-leskoDierbar be.
    According to a development, it is possible that a driver's cab is formed, which is arranged centrally with respect to a longitudinal axis of the vehicle on the first axle. The advantage here is that the view of the component to be transported can be improved by a centrally located cab.
    Furthermore, it can be provided that a clear length of the free space between 3m and 20m, in particular between 4m and 18m, preferably between 7m and 15m. The advantage here is that a vehicle with such a large clearance length of the free space is suitable for a variety of purposes and a large number of different components of the Flubeinrichtung can be included, the components can be lowered even within the vehicle down to the ground.
    In addition, it can be provided that the two axle carrier and the connecting structure are modular and each formed as a separate component group, wherein the connecting structure is coupled on a first side with the first axle, whereby a first connection point is formed, and on a second side with is coupled to the second axle, whereby a second connection point is formed. An advantage of this design of the vehicle is that can be provided by the modular design of different lengths vehicles, the two axle must not be redesigned or need only be slightly adapted. The various lengths of the vehicle can be achieved by varying the length of the connecting structure. As a result, on the one hand the Flerstellkosten for such a vehicle can be lowered and on the other hand, the quality of the vehicle can be improved due to the standardization of certain components.
    Furthermore, it may be expedient if, in the region of the connecting construction, a sensor, in particular in the form of strain gauges, is arranged which detects a torque introduced into the connecting structure, which torque can be compensated by inclining one of the two axle carriers. The advantage here is that it can be compensated voltages occurring in the connecting structure. This may be necessary in particular during operation of the vehicle on an uneven surface.
    Alternatively or additionally, it may be provided that both on the first and on the second axle a tilt sensor is arranged, by means of which the current inclination of the axle can be measured, with a control can be set in such a way, in which a difference between inclination differences of the axle by Adjustment of the wheel pairs can be compensated. The advantage here is that this can be compensated in the connection structure occurring stresses. This may be necessary in particular during operation of the vehicle on an uneven surface.
    Furthermore, it can be provided that at least one extendable support is arranged on the first axle carrier and / or on the second axle carrier, wherein the support is arranged in particular laterally of the axle carrier near the free space. The advantage here is that an extendable support can relieve the tires of the vehicle on the side of the component to be transported and thereby the stability of the vehicle can be increased. The support can be extended in particular when the vehicle is stationary. Furthermore, it may also be useful if several Stüzen are formed. The supports should be arranged as close to the lateral edge of the vehicle in order to achieve the best possible Abstüzwiring.
    Furthermore, it may be expedient if the axle carriers are each coupled to the connecting construction at a connecting plane. The advantage here is that such a connection plane can be easily formed to reach the defined area for connecting the axle with the connecting structure.
    Furthermore, it can be provided that the connecting plane is formed by at least one connecting plate. The advantage here is that a connecting plate is ideally designed for receiving fastening means and beyond the connecting structure by means of the connecting plate is well positioned relative to the axle beams.
    In addition, it can be provided that the connecting structure and the axle carrier are connected to one another by means of a thermal joining connection, preferably a welded connection. The advantage here is that a thermal joint connection is easy to manufacture and also has a high strength.
    Alternatively, it may be provided that the connecting structure and the axle are connected to each other by means of at least one fastening means, preferably a screw. The advantage here is that such a connection is non-destructive solvable and thus, if necessary, a vehicle already in use can be provided with a new connection structure and thus the length of the vehicle can be changed in retrospect.
    According to a further development, it is possible for a centering bolt in the connection point to cooperate with a bolt receptacle corresponding thereto, whereby the first axle support is positioned relative to the connection construction and / or the second axle support is positioned relative to the connection construction. The advantage here is that the position accuracy between the connecting structure and axle can be improved. Furthermore, the assembly between connecting structure and axle is facilitated by this measure. In addition, the centering bolts can be used for power transmission between connecting structure and axle.
    Also advantageous is an expression, according to which it can be provided that the connecting structure is designed as a framework. The advantage here is that a connecting structure designed in this way can have the greatest possible rigidity with the lowest possible weight.
    In addition, provision may be made for supply lines running between the first axle carrier and the second axle carrier, such as power lines and / or hydraulic lines, to be guided in the region of the connecting structure, wherein the supply lines are coupled in the region of the connection point by means of a coupling. The advantage here is that the supply lines when assembling the connecting structure with the axle beams can be easily coupled or that in a possible disassembly of the connecting member and the axle, the supply lines can be easily separated.
    Furthermore, a vehicle fleet may be provided with at least two vehicles with lateral Flubeinrichtung, wherein both vehicles are formed according to the above description, and wherein the first axle and the second axle of both vehicles ident ident are formed and wherein the connecting structure of the two vehicles has a different length. The advantage here is that such a vehicle fleet is efficient and inexpensive to manufacture.
    Furthermore, in the production method for producing a vehicle with a lateral lifting device, it can be provided that the production method comprises the following method steps: providing a first axle carrier; - Providing a second axle carrier; - providing a connection structure; - Providing the lifting device; - Connecting the connecting structure with the first axle carrier and the second axle carrier; - Installing the lifting device.
    An advantage of the method according to the invention is that the quality of the vehicle can be improved by the defined method steps and at the same time the productivity during assembly of the vehicle can be increased.
    The orientation of the two masts is substantially vertical. For the sake of simplicity, this document only speaks of a vertical displaceability of the fork holder receptacle or of a vertical alignment of the rails of a lifting mast. However, it is also possible that the masts are designed to be adjustable in their angle, or that there complete vehicle can be tilted laterally. Deviation from the vertical due to the vehicle propensity or due to the inclination of the lifting mast is also considered to be substantially vertical and is therefore included in the scope of protection. If this document speaks of vertical, deviations of the absolute vertical caused by the inclination of the vehicle are therefore also meant. As described here, the term horizontal alignment is used, in which also small deviations in angle are included due to the inclination of the vehicle.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    1 shows a perspective view of a vehicle 1 with lateral Hubein-direction 2. Such a vehicle 1 is referred to in the jargon as a sideloader.
    In Figures 2 and 3, the vehicle 1 is shown in further illustrations.
    In the figure 4, the lifting device 2 is shown in a perspective view.
    The following description is based on a synopsis of the various representations of the first embodiment of the vehicle 1 in Figures 1 to 4, wherein not all of the figures all component numbers are entered, but for clarity, the components have been designated only in those figures in which you particularly are clearly visible. It is understood that it is clear to those skilled in the art how to combine different views from different angles.
    The vehicle 1 has a first axle carrier 3 and a second axle carrier 4, which are coupled together by a connecting structure 5. In particular, the two axle carriers 3, 4 and the connecting structure 5 are coupled to one another such that a free space 6 results on one side of the vehicle 1. Seen in the plan view of FIG. 3, the vehicle 1 has a U-shaped shape, wherein the two parallel legs of the U by the first axle 3 and the second axle 4 are formed.
    In order to make the free space 6 as large as possible, the connecting structure 5 is seen in plan view of the vehicle 1 arranged laterally off-center. In a preferred embodiment, the connecting structure 5 is arranged as far as possible on the edge 12 of the axle carrier 3, 4, so that the free space 6 is as large as possible. In other words, seen in plan view, the connecting structure 5 to the central longitudinal axis 7 of the vehicle 1 as far as possible.
    Another factor for the size of the free space 6 is the width of the connecting structure 5. The narrower the connecting structure 5 is carried out, the wider the free space 6 can be. The connecting structure 5 should therefore have the highest possible stiffness and torsional stiffness with the smallest possible dimensions. This can for example be achieved in that the connecting structure 5 is designed in the form of a framework. For this purpose, individual sheets may be welded together to form the connecting structure 5.
    In an alternative variant can also be provided that the connecting structure 5 is welded together in a profile construction of different individual sheets, or that a sheet is bent into a frame profile.
    Also, the axle 3, 4 may be designed as a sheet metal construction, with individual sheets for each axle 3, 4 may be welded together. In particular, it can be provided that the axle beams 3, 4 and the connecting structure 5 are prefabricated in each case as their own independent welded constructions and joined together in a further assembly step.
    As a longitudinal direction 8 of the vehicle 1, that direction is defined which is parallel to the direction of travel of the vehicle 1. Seen in plan view, the transverse direction 9 of the vehicle 1 is formed at an angle of 90 ° to the longitudinal direction 8 of the vehicle 1.
    Preferably, it can be provided that the vehicle 1 has a main movement direction, wherein this is selected such that the first axle carrier 3 is forward in forward travel, so that the first axle carrier 3 can also be referred to as a front axle carrier. The second axle carrier 4 can be analogously referred to as a rear axle carrier.
    Furthermore, it can be provided that a driver's cab 10 is arranged on the vehicle 1, wherein the driver's cab 10 is preferably arranged on the first axle carrier 3. In the embodiment of the vehicle 1 according to FIGS. 1 to 3, the driver's cab 10 is seen in the direction of travel, arranged on the left side of the vehicle 1. In other words, it can be provided that the driver's cab 10 is arranged on the same side of the vehicle 1 as the connecting structure 5.
    Furthermore, it can be provided that a support plane 11 is formed on the first axle carrier 3 and / or on the second axle carrier 4, on which elongated objects received by the lifting device 2 can be deposited. The support plane 11 may be formed by the described arrangement of the driver's cab 10 and the connecting structure 5.
    The first axle carrier 3 preferably comprises a first wheel pair 13 and the second axle carrier 4 preferably comprises a second wheel pair 14. The wheel pairs 13, 14 are preferably arranged on a pendulum axle. Alternatively, it can also be provided that the wheel pairs 13, 14 each have an independent suspension. By adjusting the distance of the welded construction of the axle carrier 3, 4 relative to the pairs of wheels 13, 14 can be an angular inclination of the axle 3, 4 and thus the Flubeinrichtung 2 adjustable. This can be achieved, in particular, by arranging on one side of the respective pair of wheels 13, 14 an adjustment device, such as a hydraulic cylinder, with which one side of the axle 3, 4 can be raised relative to the wheel and thereby an inclination is adjustable.
    In a development, it can also be provided that a sensor is arranged in the region of the connecting structure 5, which measures the twisting of the connecting structure 5 or the torque occurring at the connecting structure 5. By means of the sensor data, an excessive distortion of the connecting structure 5 can be compensated by means of the individual adjusting devices of the wheel pairs 13, 14. This may be necessary in particular if the connecting structure 5 has a large length and thus has only a slight torsional rigidity and if at the same time the ground on which the vehicle 1 is to be operated is very uneven.
    In particular, it can be provided that the first pair of wheels 13 is steered in order to be able to control the vehicle 1. Furthermore, it is also conceivable that alternatively or in addition to the second pair of wheels 14 is directed. If both the first pair of wheels 13 and the second pair of wheels 14 are steered, the possible radius of curvature of the vehicle 1 can thereby be reduced.
    Furthermore, it can be provided that, in order to increase the possible payload of the vehicle 1, a further pair of wheels is arranged on the first axle carrier 3 and / or on the second axle carrier 4.
    The axle beams 3, 4 can be seen in plan view, have approximately a rectangular cross-section. In particular, it can be provided that the first axle carrier 3 serves to receive the driver's cab 10 and the second axle carrier 4 serves to receive a drive motor. The vehicle 1 can be driven by means of an internal combustion engine, such as a diesel engine or a gas engine, which are preferably arranged in the second axle carrier 4. This internal combustion engine may, for example, be coupled to a generator, wherein all actuating and travel drives of the vehicle 1 may be designed in the form of an electric motor.
    Alternatively, it can be provided that the engine is coupled to a hydraulic ikaggregat and that all actuators or traction drives are designed in the form of a hydraulic motor.
    In yet another embodiment, it may be provided that all actuators or traction drives are designed in the form of an electric motor, wherein the drive energy is not provided by a generator, but by a battery.
    The distance or the arrangement of the first axle carrier 3 and the second axle carrier 4 to each other determines not only the length 15 of the vehicle 1 but also the light length 16 of the free space. 6
    In particular, it can be provided that similar vehicles 1 with different lengths 15 can be produced, the axle carriers 3, 4 being constructed identically in vehicles of different lengths 15 and only the length of the connecting structure 5 being varied.
    In some applications, it may be necessary that the clear length 16 of the free space 6 is greater than a length of a component to be transported 17. This can be achieved that the transported component 17 of the lifting device 2, which between the two axle beams 3, 4 is disposed within a width 18 of the vehicle 1 can be lowered almost to the ground. This makes it possible for the lowermost floor of a shelf to be loaded by the vehicle 1, without the component 17 to be transported being previously pushed out of the vehicle 1 from the side. This brings in particular the advantage that the vehicle 1 even in narrow aisles, which are barely wider than the width 18 of the vehicle 1 can load a lower shelf level.
    In order to make the clear length 16 of the free space 6 as large as possible, it is provided that the vehicle 1 has a first mast 19 and a second mast 20, which are spaced from each other and which have a first fork holder receptacle 21 and a second fork holder receptacle 22 , The fork holder receptacles 21,22 are in particular formed on a carriage 23, which is received in the lifting mast 19, 20 and which is displaceable in the vertical direction relative to the axle beams 3, 4, whereby the component 17 to be transported can be positioned in the vertical direction. It may be particularly advantageous if the two carriages 23 of the two masts 19, 20 can be raised or lowered synchronously to each other.
    Furthermore, it can be provided that the vehicle 1 comprises a fork holder 24, wherein the fork holder 24 may be coupled to the first fork holder receptacle 21 on a first side 25 and the second side 26 of the fork holder 24 may be coupled to the second fork holder receptacle 22. The connection between fork holder receptacle 21, 22 and fork holder 24 can be designed in particular in the form of a releasable connection, so that the fork holder 24 can be easily decoupled from the lifting masts 19, 20.
    Furthermore, it can be provided that one or more support fork 27 are accommodated on the fork holder 24, wherein the support forks 27 can be accommodated in the longitudinal direction 8 displaceably on the fork holder 24. As a result, the distance between two adjacent support forks 27 can be varied. The support forks 27 may be in the form of conventional forklifts. In an alternative variant, it is also possible that the support forks 27 have a different shape in order to be able to convey various components 17.
    Furthermore, it can be provided that between the two lifting masts 19, 20, a strut 28 is formed, wherein the two masts 19, 20 can be supported relative to each other by the strut 28, whereby the rigidity of the lifting device 2 and the complete vehicle 1 are increased can. As can be clearly seen from FIG. 4, it can be provided that the lifting device 2 is formed by the two lifting masts 19, 20 and the strut 28 into a unit. The strut 28 may be formed by simple shape profiles, which are arranged between the two masts 19, 20. Furthermore, it is also conceivable that the brace 28 example meadow in the form of a framework is performed. It can be advantageous, in particular, if two struts of the strut 28 have as great a distance as possible from one another, a first strut being connected in particular to the lower end of the lifting masts 19, 20 and a second strut being connected to the upper end of the masts 19, 20 is. As a result, the stiffening effect of the brace 28 can be increased.
    As can be seen particularly well from a combination of FIGS. 1 and 4, the lifting device 2, which comprises the first lifting mast 19 and the second lifting mast 20, is received in the free space 6 of the vehicle 1. In particular, it can be provided that on a first side 29 of the first mast 19, a first guide unit 30 is arranged and on a second side 31 of the second mast 20, a second guide unit 32 is arranged. The guide units 30, 32 serve to accommodate the lifting masts 19, 20 in the transverse direction 9 of the vehicle 1 slidably in the free space 6 can. As a result, the support forks 27 and thus the component 17 to be transported can be pushed laterally out of the vehicle 1 in the transverse direction 9.
    Furthermore, it can be provided that the strut 28 are connected to a second side 33 of the first lifting mast 19 or to a first side 34 of the second lifting mast 20. The connection between the strut 28 and masts 19, 20 may be designed in particular in the form of a welded joint.
    Alternatively, it can also be provided that the strut 28 is connected by means of a fastening means with the lifting masts 19, 20.
    Furthermore, it can be provided that the two guide units 30, 32 each have two main guide rollers 35, which are arranged on the lifting device 2 such that a rotational axis 36 of the main guide rollers 35 is aligned in the longitudinal direction 8 of the vehicle 1. Preferably, the two main guide rollers 35 of a guide unit 30, 32 are arranged spaced from each other. As a result, in addition to a vertically acting force, a torque acting on the lifting masts 19, 20, which are applied on the basis of the mass of the component 17 to be transported, can also be absorbed by the main guide rollers 35.
    In particular, it is provided that the main guide rollers 35 cooperate with a guide rail 37 which is formed in the first axle carrier 3 and in the second axle carrier 4.
    Furthermore, it can be provided that two drive units 38 are formed, which serve to adjust the lifting masts 19, 20 in the transverse direction 9 of the vehicle 1. The drive units 38 can be arranged in particular in the vicinity of the axle carrier 3, 4, so that the two drive units 38 have the greatest possible distance from one another. It can thereby be achieved that the lifting device 2 has a high stability. The drive unit 38 may comprise, for example, a hydraulic cylinder 39, which is designed to be able to move the lifting masts 19, 20 in the transverse direction 9. Preferably, it can be provided that the two drive units 38 are switched synchronously with each other in order to achieve a uniform ejection of the two masts 19, 20.
    In an alternative variant, it may be provided that the drive unit 38 comprises a servomotor with a traction means, such as a toothed belt or a chain, the two lifting masts 19, 20 are coupled to the traction means, whereby the adjustment of the lifting device 2 can be achieved. In yet another embodiment, it can be provided that the drive unit 38 has, for example, an adjusting spindle, such as a threaded spindle.
    Furthermore, it can be provided that the first guide unit 30 or the second guide unit 32 has a stabilization module 40, which serves for guiding or positioning the main guide rollers 35 in the longitudinal direction 8 of the vehicle 1. The stabilization module 40 can cooperate in particular with a stabilization rail 41, which can be arranged in the first axle carrier 3 or in the second axle carrier 4. In particular, it can be provided that the stabilization module 40 comprises one or more sliding elements 42, which are received in the stabilization guide rail 41 and thereby the sliding of the stabilization module 40 in the stabilization guide rail 41 it can be enough. Another embodiment of the stabilization module 40 is shown in FIG.
