Gas Spring End Member Rib Structure for Uniform Wall Compression

The end member is segmented into multiple rib wall portions (first, second, third, and fourth rib wall portions) that are spaced apart from one another. This segmentation allows each rib to independently support and distribute compression forces uniformly across the flexible wall, preventing the variations in compression that occur with traditional crimp ring designs. The gaps between ribs enable the flexible wall to be evenly compressed without creating stress concentration points.

Different regions of the end member are given different structural qualities through the rib configuration. The rib wall portions provide localized structural support where needed, while the gaps between ribs allow for uniform compression distribution. This local quality approach ensures that each area of the flexible wall receives appropriate compression without over-compression or under-compression in specific zones.

The segmented rib structure divides the axial load support function across multiple independent rib wall portions. Each rib can deflect and absorb load independently, preventing excessive flexing of the entire end member. This segmentation maintains pressurized gas retention by distributing the flexing stress across multiple points rather than allowing concentrated flexing that would compromise the seal.

The end member employs a composite structure combining rigid rib wall portions with the flexible spring member. This composite design allows the rigid ribs to bear axial loads while maintaining uniform compression on the flexible wall, preventing the kind of excessive flexing that would lead to pressurized gas loss while still supporting the required axial loads.
