  • a frequently used method for fastening pressure vessels in the vehicle or under the vehicle uses tank straps, which allow a tolerance compensation when filling the container, but do not offer a structural influence of the container stiffness on the body of the vehicle.
  • a deflection of the pressure tank is ensured in plastic deformation of the body, for example in a side crash, which is to ensure protection against damage to the pressure tank.
  • the transmission of the crash energy takes place solely by the components or load paths of the body.
  • a generic pressure vessel preferably has a cylindrical construction, in which a cylindrical pressure vessel jacket is closed on both sides by bulged, outwardly curved bottoms.
  • the pressure vessel wall can be constructed, for example, in three layers and comprise an inner layer, a middle layer of a fiber composite plastic and an outer layer of a further fiber composite plastic.
  • the inner layer is a plastic liner made by blow molding or rotary / sintering process or thermoforming process.
  • the plastic liner reinforcing middle layer is preferably wound in a wet winding process as a fiber winding on the plastic liner.
  • the fiber winding consists of, for example, carbon, aramid, glass and / or boron fibers embedded in a matrix of thermosets or thermoplasts.
  • the fibers are applied to the plastic liner in different fiber orientations.
  • the preferably impact-absorbing outer layer may likewise be a fiber winding which is wound onto the middle layer in a wet winding process.
  • the outer winding thus formed consists, for example, of carbon and / or glass fibers embedded in a matrix.
  • the finished high pressure container has, for example, on a stirnsei term container bottom on an outwardly projecting neck piece, in which a valve is integrated. Otherwise, the high-pressure vessel is usually completely smooth on the outside. In its installed position, the high-pressure container is positionally secured in position by means of tension bands, which surround the smooth surface Zylin derwand the high-pressure vessel.

  • a connecting pin is connected to a bearing in a connection point.
  • the connecting pins and / or the bearings are each connected to the pressure vessel in a pressure tank connection area and extend from the outer surface away from the pressure vessel.
  • the pressure tank connection areas each have an extension.
  • the connecting pin and the bearing are formed and arranged in the connection point at least in regions such that the extension E is guided kinematically by a movement of the bearing and / or the connecting pin with only one translational degree of freedom.

  • the object of the present invention is to provide a pressure vessel and a method for producing an outer shell for such a pressure vessel, which can be integrated into the body structure in a simple manner as a stiffening element.
  • a hollow cylindrical extension is formed at both axial ends of a cylinder-like central region of an outer shell, which over the projects beyond the respective end region and merges at its open end into a plurality of fastening elements which each have a plane connection surface arranged radially on the outside.
  • the method for producing an outer shell for such a pressure vessel comprises the steps of: wrapping an inner container and / or a respective winding mandrel adjoining axially thereto with a continuous fiber material, so that at both axial ends of the cylinder-like middle region of the outer shell hollow cylindrical extension is formed, which projects beyond the respective end region. Curing of the outer shell and mechanical processing of the respective extension take place in such a way that the fastening elements with the respective planar connection surfaces are formed therefrom.
  • the wound continuous fiber material can be provided with a matrix material before curing.
  • the continuous fibers may already be preimpregnated with the matrix system.
  • the fastening elements can be designed as tabs.
  • the tabs may each have an opening through which a screw can be guided in order to screw the pressure vessel to the body structure.
  • the fastening elements can be introduced into the hollow cylindrical extension by a first machining operation, in particular by milling or cutting.
  • the planar connection surfaces can then be introduced into the fastening elements by a second machining operation, in particular by milling.
  • at least the hollow cylindrical extension of the outer shell may have a round outer contour and a polygonal inner contour with flat inner surfaces and / or round inner surfaces.
  • the planar connection surfaces can be formed in the region of the pla nen inner surfaces. As a result, any number of connection surfaces in different angular positions can be realized.
  • the connection areas can thus be freely positioned within the axis of rotation and designed independently of the vehicle.
  • the outer shell can be made of a fiber-reinforced, preferably a continuous fiber reinforced plastic.
  • the outer shell can have a jacket structure with a radially inner laminate layer and a radially outer laminate layer.

Due to the superficial damage of the outer laminate layer for the representation of the planar bonding surfaces in the milling process, only the glass fibers but not the carbon fibers of the inner laminar layer are released. Therefore, the structural properties of the carbon fiber matrix composite are maintained, and corrosive interactions with metallic components in the area of connection of the body structure of the vehicle can be avoided.

  • the inner contour 22 is designed with sixteen corners with eight planar and eight round alternating inner surfaces 26, 28. In the angular regions of the planar inner surfaces 26, the winding radius of the inner contour 22 is significantly greater than at the circular inner surfaces 28 of the inner contour. As a result, the thread tension in the winding process is unequal, which is why, in the areas with higher radii, detachment of the thread from the tool core can occur. Due to the constant radius of the outer contour 24 of the shell structure 30 of the outer shell 12, a higher wall thickness and thus a partially lower fiber volume content are formed in these regions.

  • the planar connection surfaces 38 are introduced into the fastening elements 36 by a second machining operation, for example by milling.
  • the fastening elements 36 are designed as tabs 36A, which each have a fastening opening. Through the mounting holes screws can be performed to screw the pressure vessel 10 with a body structure, not shown, of a vehicle.
  • planar attachment surfaces 38 are formed in the region of the planar inner surfaces 26. Furthermore, the radially inner laminate layer 32 remains undamaged when the planar connection surfaces 38 are formed. Thus, only the glass fibers of the outer laminate layer 34 but not the carbon fibers of the inner laminate layer 32 are released by the surface damage of the outer laminate layer 34 to depict the planar bonding surfaces 38 in the milling process. Therefore, the structural properties of the carbon fiber matrix composite of the inner laminate layer 32 are advantageously maintained. In addition, corrosive interactions are avoided to Metalli's components in the connection area of the body structure of the vehicle in an advantageous manner. LIST OF REFERENCE NUMBERS
