Abstract
An assembly includes a flexible wall, that can at least partially define a spring chamber for containing pressurized gas. The flexible wall can include at least one mounting bead formed along an end thereof. A compression core can be disposed along the exterior of the flexible wall in abutting engagement with the mounting bead. The compression core can be captured between the mounting bead and a portion of the flexible wall such that inflation of the spring chamber biases the flexible wall, mounting bead and compression core outward and into engagement with an end member to form a gas spring assembly. A suspension system and a method of assembly are also included.
