Cryogenic fluid storage unit and corresponding production method

A cryogenic fluid storage unit, comprising an internal reservoir inwardly delimiting a cryogenic fluid storage volume, an external reservoir housing the internal reservoir, and a suspension suspending the internal reservoir in the external reservoir;

• the suspension comprising a link including:
• a cuff made of a composite material with a central axis;
• a proximal link of a proximal axial end of the cuff to the internal reservoir;
• a distal link of a distal axial end of the cuff to the external reservoir;
• the proximal link comprising:
• a body closing the proximal axial end of the cuff, the body having an external surface defining an external tapered bearing surface coaxial with the central axis and engaged inside the proximal axial end, and
• a ring connected to the internal reservoir, the ring having an internal surface defining an internal tapered bearing surface coaxial with the central axis and surrounding the proximal axial end, the proximal axial end of the cuff being clamped between the external tapered bearing surface and the internal tapered bearing surface.
