    15 20 25 30 35 Depending on whether the trailer is to be braked or not, it receives air from the compressed air tank which is led out to the spiral hose for "control" while the "Supply" line is always pressurized. The air in the compressed air tank always passes the trailer brake valve before it is led to the trailer. The trailer beam usually consists of a pipe construction and is used for mounting various parking or suspension devices and makes connections for air ie and electricity easily accessible, and thus convenient to use, to connect to and from the trailer. Because the spiral hoses are mounted at a certain height above the tractor's chassis, they can hang the chassis freely in the air and do not wear against, and do not get stuck in, or in other parts between the cab and the trailer. The trailer beam is mounted to the chassis in such a way that it is easy to disassemble and is easily accessible for service.
    At least two air outlets are arranged on the trailer beam to which spiral hoses can be connected and which hang between the tractor and the trailer. A spiral hose is used for system pressure, so-called "supply", s.k. the trailer beam is also one or more electrical cables which i.a. lighting. Because the tractor must have a larger space and one for steering pressure, "control". On mounted, and suspended, used for the trailer behind the cab that allows the trailer to rotate freely on the tractor's turntable, there is not much space to place a compressed air tank. There is thus a need to eliminate the space requirement for this component but still create the possibility of storing compressed air near the trailer.
    It is also desirable to generally minimize the number of components on the vehicle, partly to reduce the total weight of the vehicle, partly to reduce the cost but also to simplify the manufacture of the vehicle.
    It is previously known to store compressed air in tanks integrated with other parts of a vehicle. US2007102913 describes, for example, such a solution where a storage device, a tank, containing compressed air for various pneumatically driven units in the vehicle, also functions as part of the vehicle frame. In this specific case, these are tubular crossbeams arranged in the frame between the longitudinal and supporting main beams of the chassis. These tubular crossbeams are designed with enclosed interior spaces that form compressed air tanks while also forming stiffeners in the vehicle frame.
    A disadvantage of this solution is that cracks can occur in the steel walls of the tanks because the frame is somewhat flexible and moves in relation to the loads to which the frame is subjected. If the vehicle is driven on uneven roads with large loads, the movements in the frame will be relatively large. The constant movements in the vehicle frame can eventually exhaust the metal in the tanks and lead to cracks forming. If a crack occurs in the outer casing of the compressed air tanks, the compressed air leaks out, whereby the pressure can drop dramatically. This can jeopardize important pneumatic functions in the vehicle or in the trailer, for example, brake failure can occur.
    SUMMARY OF THE INVENTION An object of the invention is to solve the above-mentioned problems and to demonstrate a device for storing compressed air and which provides compressed air near the source of consumption without for this purpose taking up extra space on the vehicle through a separate conventional compressed air tank.
    A further object of the invention is that the compressed air tank does not risk being subjected to mechanical stresses of the kind which can lead to crack formation and thus undesired compressed air loss. 10 15 20 25 30 35 A further object of the invention is that the compressed air container should be easily accessible, convenient to use and easy to disassemble for service.
    A further object of the invention is to reduce the number of components on the vehicle and thereby reduce the component costs and the weight of the vehicle.
    A further object of the invention is to simplify the assembly of the vehicle.
    The invention relates to a new way of storing compressed air, compressed air, for use in one or more compressed air systems in trucks, placed in, for example, a trailer. The invention relates to a compressed air container or tank which is integrated with a support already existing on the vehicle support brackets intended for hanging air hoses, couplings, cables, cable connectors, etc. for connection to a trailer and for driving e.g. one or more compressed air systems in said trailer. The air hoses and electrical cables are connected to the trailer, whereby the compressed air is used e.g. for the trailer's braking system and the cables are used i.a. for supplying electricity to the trailer's lighting, for control signals to ABS / EBS systems and for other data communication such as e.g. for reversing cameras, temperature data from refrigerated trailers etc.
    The invention frees up valuable space on the tractor and reduces the number of components included in the tractor, which reduces the total weight of the vehicle. Since a conventional compressed air tank can be eliminated, the weight of the vehicle and component costs are reduced and the manufacture of the vehicle is simplified, which makes the assembly cheaper.
    Further features and advantages of the invention will become apparent from the following, more detailed description of the invention, and from the accompanying drawings and other claims. BRIEF DESCRIPTION OF THE DRAWINGS The invention is described in more detail below in some preferred embodiments, with reference to the accompanying drawings.
    Figure 1 shows an example of a truck according to the invention from the side with a trailer beam arranged behind the cab.
    Figure 2 shows a perspective view obliquely from behind of the tractor and its cab and in more detail the location of the trailer beam.
    Figure 3 shows a perspective view obliquely from behind, and in more detail the trailer beam according to the invention.
    DESCRIPTION OF PREFERRED EMBODIMENTS Figure 1 shows a common truck 1, here consisting of a tractor 2 with a connected trailer 3. directly behind the tractor 2's cab 5, trailer beam 4, with an integrated compressed air tank.
    Mounted on the tractor 2 is a construction according to the invention, a so-called which is provided The trailer beam 4 is usually fixedly mounted to the chassis 6 of the tractor 2, and preferably to its longitudinal beams 7. An alternative location is that the trailer beam 4 is mounted directly against the rear wall 8 of the cab 5 (not shown). Spiral hoses 9a, b for compressed air are connected between the integrated compressed air bearings of the trailer beam 4 and the trailer 3. Electrical cables (not shown here) are also connected between connections arranged on the trailer beam 4 and the trailer 3 for power supply and for data transmission between the tractor 2 and the trailer 3.
    Figure 2 shows in more detail the location of the trailer beam 4 directly behind the cab 5 of the tractor 2. Here it is shown how the two side parts or legs 10a, b of the trailer beam 4 are arranged vertically against the longitudinal beams 7a, b of the tractor 2 and are attached to them by bolts. With this mounting of the trailer beam 4 near the cab 5, a sufficient space is created behind the cab 5 for the trailer 3 so that it can be rotated around the turntable 11 of the vehicle 2 without obstacles when, for example, cornering. The upper horizontal part 12 of the trailer beam 2 is placed at such a height above the chassis 6 that it provides a comfortable working position for the user to reach all connections and so that spiral hoses 9a, b and other cables, freely in the air. when connected to the trailer 3, Figure 3 shows in more detail the device according to the invention, the trailer beam 4. The trailer beam 4 is preferably made of a circular tube of metal, e.g. of steel, and is for example bent in an upside-down U-shape. The tube is closed at both ends, metal lids 13a, b, for example by means of welded and thus forms an inner closed space which can enclose a certain predetermined volume of air. The pipe can typically be about 80 mm in diameter but can of course have both a larger and smaller diameter. The tube does not have to be circular but can have a square cross-section or other appropriate cross-section.
    On the outside of the pipe, and more precisely at its upper horizontal portion 12, various brackets 14a-c and suspension devices for e.g. cable connectors and other details that the trailer beam 4 is intended to support. The brackets 15a, b, here in the form of metal plates, are arranged for mounting the trailer beam 4 at the tractor 2 and these brackets 15a, b are arranged in the lower part of the trailer beam 4 and are preferably placed on the inside, and directed towards each other. the legs 10a, b, at their connections for air outlets 16a, b, are arranged at the top of the trailer beam 4 on a dedicated bracket 14b. Connection and disconnection of air is controlled by a therefore arranged valve 18 which communicates with the trailer beam 4 via a further connection 19. The two spiral hoses 9a, b are arranged to be connected to the trailer 3, and supply system pressure, "supply", and control pressure, " control ".
    The above description is primarily intended to facilitate the understanding of the invention. The invention is therefore of course not limited to the above-mentioned embodiments, but also other variants of the invention are possible and conceivable within the scope of the inventive concept and the scope of protection of the following claims.
