Definitions

  • the present invention relates to a container arrangement, in particular a container arrangement of an air pressure system of a commercial vehicle, such as a trailer or semitrailer.
  • Such container arrangements are used in particular to supply the chassis of a vehicle with compressed air.
  • storage containers or container arrangements are provided which can provide compressed air corresponding to an air spring or similar peripheral units.
  • such containers are constructed from a cylindrical housing, the ends of which are closed by caps. These caps are welded abutment with the cylindrical housing.
  • the problem with such containers is that due to the loads on the weld often leaks occur and beyond the life of the containers is greatly reduced.
  • such containers are often incapable of storing a high pressure gas.
  • a container arrangement in particular an air pressure system of a utility vehicle, comprising a first area and a second area, wherein the first area and the second area together enclose at least a part of a container interior, the first area and the second area being connected to one another via a joining area are connected, and wherein the joining region is loaded under load from the inside of the container to thrust.
  • the container arrangement consists of at least two separate parts, of which one part comprises the first region and the second part comprises the second region.
  • the container assembly thus during manufacture consists of two separate parts, which are joined together and thus form a coherent element in the final state.
  • the first and the second region are in this case arranged such that they together enclose at least a part of a container interior.
  • the first region and the second region are thus part of a container which encloses a volume on all sides, so that the container can be pressurized.
  • the first region and the second region are connected to one another via a joining region, wherein the connection of the first region and the second region is advantageously designed such that it is fluid-tight, in particular gas-tight.
  • the connection of the first and the second region can be reversible, ie detachable.
  • the first Area and the second area irreversible, ie not non-destructively separable from each other, interconnected.
  • the joining region may thus be defined by those regions of the first and second regions which adjoin one another and between which a connection is provided.
  • a particular advantage of the invention lies in the fact that the joining region is subjected to thrust under load from the container interior side.
  • the joining region is designed or arranged such that when the container is pressurized, the joint between the first region and the second region is not or only insignificantly stressed or subjected to tensile stress, but only or at least predominantly one Shear stress is exposed.
  • the material loads acting on the joint between the first and second regions can advantageously be reduced.
  • the first region and the second region are materially connected to one another, in particular welded or soldered.
  • the joining region can therefore be, in particular, that section of the first and second region which forms or provides a material-bonding connection or contact between the first and second regions.
  • the cohesive connection can be created particularly advantageously by welding or soldering.
  • the joining region is thus expediently formed or formed as a welding or soldering or welded or soldered region. Especially a weld leads to a joint between the first and second area, which can absorb particularly high forces.
  • the first region has a first joining section and the second region has a second joining section.
  • the joining sections thus represent in particular those sections of the first and second Range is about which a cohesive connection with the other area is created.
  • the first and the second joining portion are formed substantially parallel and / or concentric with each other.
  • those surfaces or the joining surfaces, between which a cohesive connection is made be arranged facing each other.
  • the peripheral surfaces ie inner circumferential surface of the outer region and outer circumferential surface of the inner region
  • substantially parallel is to be understood in particular such that deviations from plus / minus 5 °, preferably plus / minus 3 ° from the parallel axis
  • the surfaces of the joining regions (ie the joining surfaces) on which the material is present can also represent end faces of the respective joining sections, which thus advantageously
  • "oriented essentially in the same direction” means that the frontal surfaces of the joining regions do not have to be exactly parallel to one another, but can also have a certain inclination to one another, but are oriented essentially in the same direction. the in the range of plus / minus 5 °, in particular plus / minus 3 °.
  • the first joining section is thus located radially outside the second joining section, starting from a symmetry center line of the container arrangement, or, in an alternative embodiment, the second joining section is radially outside the first joining section.
  • the second joining portion is oriented towards a container outer side.
  • the second joining portion is directed in its geometric extension towards a container outer side.
  • the respective end face to the container outside is oriented in this direction.
  • the second joining section encloses the first joining section.
  • the first joining section and the second joining section can thus be arranged concentrically relative to one another such that the second joining section encloses the first joining section. Seen in a radial direction, the second joining section is thus arranged outside the first joining section. It is particularly preferred that the joining surface of the second joining portion is oriented towards the container interior side.
  • the first joining portion may enclose the second joining portion.
  • the two joining sections are thus advantageously formed concentrically with respect to one another, the first joining section being arranged outside the second joining section in a radial direction.
  • a section of the second area adjoining the second joining section is provided, wherein the adjacent section is oriented transversely to the second joining section.
  • a section of the second region adjoining the joint between the first and second regions is thus provided, which extends transversely to the extension of the second joint section, in particular transversely to the extension of the second joint surface.
  • the second joining section and the adjoining section are at an angle between 65 ° and 15 °, advantageously 75 ° and 105 ° and particularly preferably 85 ° and 95 ° to each other.
  • the second joining section and the adjoining section have an angle measured from the outside of the container which is between 25 ° and 110 °, preferably between 45 ° and 100 ° and particularly preferably between 70 ° and 95 °. This ensures that when pressure is applied to the container there is no or only an insubstantial force component which acts on the joint in such a way that the first joining section and the second joining section are forced radially away from one another.
  • the second joining section and the adjoining section include an angle, measured from the inside of the container, of between 25 ° and 110 °, preferably between 45 ° and 100 ° and particularly preferably between 70 ° and 95 °. This ensures that, when pressure is applied, the second joining section is pushed radially inwards against the first joining section, thereby ensuring a particularly tight connection at the joint.
  • the wall thickness of the first region and / or second region is increased in the region of the joining section.
  • the magnification is dimensioned such that the wall thickness of the first area and / or second area in the respective joining section is increased or increased in relation to an average or average wall thickness of the remaining part of the respective area.
  • only one of the joining sections has an increased wall thickness.
  • both joint sections are formed with an increased wall thickness. This can ensure that the joint between the two areas can be made safely and reliably.
  • the ratio of the increase in the wall thickness of the first joining portion to an increase in the wall thickness of the second joining portion is 0.7 to 1.8, preferably 0.9 to 1.5 and particularly preferably 0.95 to 1.3 , It is also possible that the ratio has a lower value of at least 1, 03, preferably 1, 08. This ensures that the pressure applied to the two joining sections the forces acting on the container are optimally transmitted to ensure the most uniform possible load on the joint.
  • the wall thickness of the first region is greater than that of the second region.
  • the first region has a mean wall thickness averaged over the entire extension, which is greater than that of the second region. This is particularly advantageous because it has been found that in the case of cylindrical containers, the circumferential surface is exposed to a greater load than the respective end faces.
  • the first region forms at least one, preferably radially circumferential part of a preferably cylindrical circumferential wall of the container.
  • the container can thus be formed as a geometric body having a peripheral or peripheral wall, which particularly suitably corresponds to the lateral surface of a cylinder.
  • the corresponding ends of this hollow-cylindrical first region, which are thus provided on the end faces thereof, can be closed by a respective second region, so that the second region forms a bottom or cover of the container.
  • the second region is at least partially concave or convex. In a concave configuration of the second region, this is bent at least partially towards the container interior side.
  • This embodiment is particularly advantageous if, in the case of a radial arrangement of the two joining sections, the first joining section radially surrounds the second joining section. When the container is pressurized, the second joining section is thus pressed radially outwardly against the first joining section during a deformation of the concave area, whereby the operational reliability of the container arrangement can be increased.
  • a convex formation of the second region in which thus the convex region protrudes toward the outside of the container, is particularly advantageous if the second joining segment encloses the first joining section in the radial direction, since with a pressure loading tion of the second region of the second joining portion is pressed radially inwardly to the first joining portion. It is understood that not the entire second region is concave or convex, but only a maximum of that portion of the second region, which does not form the second joining portion, wherein the concave or convex portion extending over only a portion of the above-defined portion can.
  • the first and / or the second region are formed from a plastic.
  • a plastic for this purpose, particularly suitable materials such as PVC, etc. which are particularly good at welding together, whereby a particularly good cohesive connection can be provided.
  • PVC polyvinyl styrene
  • other materials or composites such as carbon fiber and / or glass fiber resin composite laminates.

  • Fig. 2 is an exploded view of a sectioned partial view of the first embodiment of the invention
  • Fig. 3 is a partial sectional view of another embodiment of the invention.
  • FIG. 1 shows a cross-sectional view of a first preferred embodiment of the container arrangement according to the invention.
  • This is more appropriate way around an axis of symmetry X is formed substantially rotationally symmetrical and has a first region 2 and a second region 4.
  • the first region 2 is in this case designed such that it substantially corresponds to a lateral surface of a cylinder.
  • the second region 4 is in this case arranged on the first region 2 such that it forms a bottom or cover, so that the first region 2 and the second region 4 enclose a container interior I and separate it from a container exterior space or a container exterior A.
  • the first region 2 and the second region 4 are connected to one another via a joining region 6.
  • the first region 2 has a first joining section 8.
  • the second area 4 has a second joining portion 10.
  • the second region 4 has a concave portion 12, which is arched to the container interior I.
  • the first joining portion 8 encloses the second joining portion 10 in a radial direction R, so that - as seen in the radial direction R - the first joining portion 8 is arranged outside the second joining portion 10.
  • FIG. 2 shows an enlarged cross-sectional view of the joining region 6.
  • the first region 2 is connected to the second region 4 both via a circumferential joint 14 and via an end-side joint 16.

  • the second joining portion 10 has a second end-side joining surface 24.
  • the frontal joining surfaces 22, 24 are formed substantially parallel to each other. It is understood, however, that these can also be at an angle to one another, which can advantageously be plus or minus 5 ° to the parallel or radial R.

Outside the second joining portion 10 and the adjacent portion 26, the second region 4 is formed with a convex portion 28 which is arched outwardly toward a container outer side A.
  • the wall thickness of the first region 2 and the second region 4 of the respective joining portion 8, 10 is formed enlarged. It is particularly advantageous if the enlargement of the wall thickness of the first joining section takes place in a direction opposite to the second joining section 10, so that the first circumferential joining face 18 is substantially flush with the adjoining peripheral face of the first area 2. In the case of a circular-cylindrical configuration, the radius of that circumferential surface on which the first circumferential joining surface 18 is provided would thus be substantially constant along the axis of symmetry X.
