Furthermore, the invention relates to a method for connecting such a pressure vessel in a body structure and a tool and a method for winding a hollow cylindrical extension of an outer shell of such a pressure vessel.
  • Pressure vessels and corresponding methods for connecting such a pressure vessel in a body structure and tools and a method for winding a hollow cylindrical extension of an outer shell of such a pressure vessel are known in numerous variations.
  • such pressure vessels can be filled, for example, with gases or pressure-liquefied gases and therefore store a considerable amount of energy. Due to the expansion of pressure vessels with very high filling pressures and the resulting change in length in the axial and radial directions during filling or pressurization, these pressure vessels are usually attached to the vehicle structure by means of flexible tank straps. These tank straps allow for tolerance compensation when filling the container, but provide no structural influence of the container stiffness on the body of the vehicle. As a result, the change in length of the pressure tank is not affected by the body and the transmission of the crash energy is carried out solely by the components or load paths of the body.
  • connection concepts for pressure vessels in a body structure are already known, but these usually have a fixed and / or floating bearing for tolerance compensation and / or require due to the mounting accessibility a variety of additional holders for the realization of sufficient connection points to the vehicle structure.

Otherwise, the high-pressure vessel is usually completely smooth on the outside. In its installed position, the high-pressure container is secured in position by means of clamping bands in conventional practice, which surround the smooth-surface cylinder wall of the high-pressure container.

  • Embodiments of the pressure vessel according to the invention are characterized in that the structurally connected pressure vessel due to the interpretable in the fiber composite elastic compensation range allows tolerance compensation, but also forces from the vehicle structure, such as bending and torsional forces from the body stiffness and additional forces from Crashlast ton transferred, and thus can significantly contribute to increasing the lightweight construction and crash safety of the body.
