    TECHNICAL FIELD The present invention relates to a vehicle with a vehicle frame and a liquid tank as well as a liquid tank for a vehicle. BACKGROUND AND PRIOR ART Liquid tanks for vehicles, in particular fuel tanks and the like for heavy vehicles, are usually mounted on a vehicle frame and mounted on a vehicle frame. i.a. for static and dynamic loads. The dynamic loads can occur during operation of the vehicle, for example due to movements of the liquid in the tank which movements can be triggered by acceleration, deceleration or cornering with the vehicle, or due to rotational movements that can be transferred from the vehicle frame to the liquid tank when the vehicle is driven on uneven ground. The loads can cause damage to the liquid tank with liquid leakage as a result.
    In modern vehicles, fuel tanks with relatively thin walls are often used in order to weigh unnecessarily much. When such a tank is clamped to the vehicle by means of clamping bands or the like, the tank walls can be deformed due to the clamping force clamping exerted on the tank, which can lead to damage to the tank with liquid leakage as a result.
    A fuel tank is usually divided into sections with partitions, so-called splash bulkheads are designed with holes that are adapted to be traversed by fuel so that fuel must be available in each section. The partitions prevent fuel from splashing around in the fuel tank while driving, which reduces the dynamic load caused by the fuel while providing a vertical support in the tank that contributes to the stability and robustness of the fuel tank.
    In order to prevent the partitions from moving or overturning when they are affected by rippling fuel and / or by the rotational movements of the vehicle frame, it is known that in the manufacture of fuel tanks the outer circumferential surface of each partition connects the inner circumferential surface of the fuel tank with e.g. welded joints or by plastic cold deformation, e.g. by rolling or the like, which means that the manufacture of the fuel tank and in particular the assembly of the partition is relatively complicated and thus a time-consuming and expensive process.
    It can be difficult to achieve sufficient robustness in large fuel tanks with known partition walls as the robustness can decrease with increasing tank size. This can be a problem for customers who need a relatively large volume of fuel but who prioritize robustness must choose a fuel tank with a fuel volume that does not meet the need. In order for a fuel tank to be sufficiently robust, it must have a certain rigidity at the same time as it must be flexible so as not to damage the rotary movements of the frame. A compromise between these two conflicting requirements is difficult to achieve with known partitions.
    SUMMARY OF THE INVENTION An object of the present invention is to provide a robust liquid tank with improved strength and which is simpler and cheaper to manufacture and mount. A further object is to provide a partition wall for a liquid tank which is easy to mount and which is easily fixed in a predetermined position in the liquid tank. These and other objects are achieved by the features set forth in the appended claims.
    By utilizing the invention, it is ensured that the circumferential wall receives an effective support of the partition wall, both in the transverse direction of the liquid tank and in its longitudinal direction, which increases the robustness and strength of the tank. The partition wall is also easy to mount and acts as an effective splash guard in the tank, which splash guard reduces the dynamic load caused by the fuel, both in the transverse direction of the liquid tank and in its longitudinal direction.
    Other features and advantages of the invention will be apparent from the claims, the description of exemplary embodiments and the accompanying figures.
    BRIEF DESCRIPTION OF THE DRAWINGS In the following, embodiments of the invention are described by way of example with reference to the accompanying drawings, in which: Fig. 1 shows a motor vehicle with a liquid tank.
    Fig. 2 shows an end view of a liquid tank mounted on a vehicle frame.
    Fig. 3 schematically shows a side view of a part of the vehicle shown in Fig. 1 and a longitudinal section through a liquid tank in which a partition wall is arranged.
    Fig. 4 schematically shows a perspective view with broken away parts of the liquid tank shown in Fig. 3.
    DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION Fig. 1 shows a motor vehicle 1 with a vehicle frame 2 which comprises two elongate parallel frame side beams which are connected to each other by a number of crossbeams not shown. A liquid tank 3 is attached to one frame side beam 4 with at least one, but in this example two fastening arrangements 5. The vehicle 1 can be a heavy vehicle such as e.g. a truck or a bus or a lighter vehicle such as e.g. a passenger car. The liquid tank 3 may be intended for some form of fuel for the internal combustion engine 6 of the vehicle 1, urea for after-treatment of exhaust gases from the internal combustion engine 6, water or other liquids.
    In the present example, the liquid tank 3 is a fuel tank 3 and the internal combustion engine 6 a diesel engine. A fuel line 9 is connected to a fuel pump 10 and adapted to lead fuel from the fuel tank 3 to the combustion space of the engine 6. A minority of the remaining fuel is returned to the fuel tank 3 via a return line 11. The fuel tank 3 is also provided with a closable filling opening 12 provided with a tank cap 13.
    Fig. 2 shows that the fastening arrangement 5 may comprise a fastening member 16 whose one end is connected to an end loop 17 of a strip-shaped fastening means 18 with a fastening member 19 extending through the fastening means 16 and the end loop 17 in the form of a pin or the like. The other end of the fastening member 16 may be connected by means of a bracket 20 connected to the frame side beam 4 or to an upper end 21 of a substantially L-shaped support member 22 which may be attached to the frame side beam 4. The fastener 18, which may be an excitable strap, at least partially encloses the fuel tank 3 is adapted to abut against a support surface 29 of the support member 22. An end loop 25 of the fastener 18 on the opposite side of the end loop 17 at the fastening means 18 is connected to the lower end 26 of the support member 22 with a fastening member 27 extending through the support member 22 and the end loop 25 in the form of a pin or similar. A clamping device 28 can be arranged at the fastening means 18 between the end loops 17,25. The clamping device 28 can be used to press the fuel tank 3 against the support surface 29 to hold the fuel tank 3 in place. In an alternative embodiment, the end loop 17 facing the frame side 18 towards the frame side beam 4 can be connected directly to the bracket 20 or to the upper end 21 of the support member 22 by means of the fastening member 19, i.e. without the intermediate fastener 16.
    Fig. 2 shows that there may be an angle ot between the direction of an imaginary plane 32 through the fastener 16 and / or one end of the fastener 18 and the direction of an upper surface 33 of the fuel tank 3. The reason for the angle ot is the attachment point of the fastener 16 or for the end loop 17 in the bracket 20 or the upper end 21 of the support member is arranged below the upper surface 33 of the fuel tank 3 to provide a downward holding force.
    The fuel tank 3 shown in Fig. 2 has a rectangular cross-sectional shape with rounded corners and arcuate side portions but can also have another cross-sectional shape such as e.g. square or circular. It is also possible to combine different cross-sectional shapes with each other to obtain an asymmetric cross-sectional shape, for example a D-shaped cross-sectional shape with a rectangular or square cross-sectional shape on one side of the envertical axis of symmetry and a semicircular cross-sectional shape on the other side of the axis of symmetry. In the case of fuel tanks with a polygon-shaped cross-sectional shape, the corners may be rounded or non-rounded and the sides may be arcuate or flat.
    Fig. 3 shows a side view of a part of the vehicle shown in Fig. 1 and a longitudinal section through a fuel tank 3. The fuel tank 3 may comprise an elongate tubular part 35 formed with a circumferential wall 36. The tubular part 35 is closed at both ends with an end wall 37,38 which is connected to the circumferential wall 36 in a suitable manner, e.g. by welding. The fuel tank 3 is divided into two or fl era chambers by means of one or fl your partitions. Fig. 3 schematically shows a first chamber 39, a second chamber 40 and a third chamber 41 and a partition wall 42 extending in the vertical direction across the fuel tank 3. In the lamella joint 42, the Latformat is a number of continuous joints 44, the stem fins, 4Ü, 4l ší-nise sides' of the rnellztrnvš-iggen (42): rie-d each other and allow a fuel fl iäde in båfla iiktningaina- The partition 42, may extend under at least one fastener 18 and has an outer contour which may be adapted to abut against the inner contour of the circumferential wall 36, at least below the fastener 18. The clamping device 28, shown in Fig. 2, may be adapted to press the fastener 18 against the circumferential wall 36 which when actuated pressing force from the fastener 18 may be pressed against the partition 42 to hold in the fuel tank 3. The partition wall 42 is then formed as a vertical support wall which can prevent the circumferential wall 36 from being deformed by the clamping force the fastener 18 exerts on b the tank tank 3.
    Fig. 3 shows that the fuel line 9 and the return line 11 extend into the fuel tank 3 and open near its bottom. In an alternative embodiment, the fuel pump 10 (Fig. 1) can be arranged in the fuel tank 3 e.g. in a fuel collection chamber (not shown) or the like which may be arranged around the mouth 8 of the fuel line 9. The filling opening 12 is in the example shown arranged at the second chamber 40, which means that filling first takes place in this chamber 40, after which fuel flows via the openings 44 to the other chambers 39. 41.
    Fig. 4 schematically shows a perspective view with broken away parts of a fuel tank 3 with a partition wall 42. The circumferential wall 36 may comprise a first portion 48 which is adapted to face the vehicle frame 2 and a second portion 49 which is adapted to face away from the vehicle frame 2. The partition wall 42 can be designed as a single-wall insert which is adapted to be inserted into the tubular part 35 through an end opening before the end walls 37, 38 are mounted.
    The partition wall 42 may comprise at least a first wall portion 55 which extends visually across the liquid tank 3 and forms a transverse support for the circumferential wall 36 and at least one wall portion 57 connected to the first wall portion 55 which extends longitudinally of the liquid tank 3 and forms a longitudinal support for the circumferential wall 36. 3.
    In one embodiment, the partition 42 comprises at least a first wall portion 55 and a second wall portion 56 extending across the fuel tank 3 spaced apart and at least a third wall portion 57 extending in the longitudinal direction of the fuel tank 3 and interconnecting the first wall portion 55 and the second wall portion 56. the first wall portion 55 and the second wall portion 56 constitute transverse support for the circumferential wall 36 and the third wall portion 57 longitudinal support for the circumferential wall 36, when the fastening means 18 at least partially encloses the fuel tank 3.
    The first wall portion 55, the second wall portion 56 and the third wall portion 57 have an outer contour which is adapted to abut against the inner contour of the circumferential wall 36. In the case of a wide embodiment, the respective contour can be formed with a substantially right-angled projection 52 which is adapted to abut against the inner contour of the circumferential wall 36. The respective wall portion 55,56,57 passes via a radius 53 in the projection 52 to facilitate the insertion of the wall insert into the tubular part 35. The abutment surface of the protrusions 52 facing the inner contour of the circumferential wall 36 and the abutment surface of the circumferential wall 36 facing the protrusion 52 may be dimensioned. 42 during assembly, the outlet opening can be displaced to a predetermined position in the tubular part 35. The friction between the surfaces is then so great that rippling fuel during operation of the vehicle is not able to move or overturn the partition wall 42 after it has been mounted.
    In an advantageous embodiment, the third wall portion 57 extends closer to the first portion 48 than the second portion 49 and constitutes a vertical support in the fuel tank 3 relatively close to the vehicle frame 2 which reduces the risk of the fuel tank 3 being deformed when the fastener 18 is clamped around the fuel tank 3.
    The invention is not limited to the described embodiments, but a number of possibilities for modifications thereof should be obvious to the person skilled in the art without departing from the basic idea of the invention as defined in the claims.
