1. A gas spring assembly comprising;
a first end member; a piston assembly disposed in longitudinally-spaced relation to said first end member and including; a piston base; a piston body supported on said piston base and including a longitudinally-extending axis, a first end, a second end spaced longitudinally from said first end, a side wall extending between said first and second ends and an end wall extending transverse to said side wall along said first end, said end wall including a first opening formed therethrough, and said side wall at least partially defining a second opening along said second end of said body that is adapted to receive at least a portion of said base; and, a support post extending longitudinally between opposing first and second ends of said piston body, said first end received within said first opening of said end wall of said piston body, and said second end operatively connected to said piston base; a flexible sleeve extending between opposing first and second ends, said first end of said flexible sleeve operatively connected to said first end member such that a substantially fluid-tight seal is formed therebetween, said second end of said flexible sleeve disposed along said piston assembly such that a rolling-lobe is formed along said side wall of said piston body and a spring chamber is at least partially defined between said first end member and said piston assembly; an end closure received along said second end of said flexible wall and secured to said piston assembly such that at least a portion of said flexible wall is captured between said end closure and said end wall of said piston assembly, said end closure including a first wall portion with a third opening extending therethrough, said end closure positioned along said piston assembly such that said third opening is disposed in approximate alignment with said first opening of said end wall of said piston body; a connector fitting extending longitudinally between said end closure and said support post, said connector fitting including a first end disposed in abutting engagement with said end closure and an opposing second end operatively connected to said support post, said connector fitting including a passage wall extending longitudinally into said connector fitting from along said first end to at least partially define a fitting passage having a passage axis, said passage wall including a first annular groove extending radially-outwardly into said connector fitting; a jounce bumper assembly supported on one of said end closure and said connector fitting, said bumper assembly including: a bumper mount including a support plate and a securement pin that extends longitudinally from said support plate, said securement pin including a second annular groove disposed therealong and extending radially-inwardly into said securement pin, and said securement pin dimensioned for receipt into said fitting passage such that said first and second annular grooves can be at least approximately aligned with one another; and, a bumper body secured to said support plate; and, a retaining member at least partially received within said first and second annular grooves to retain said jounce bumper assembly on said one of said end closure and said connector fitting such that said jounce bumper assembly can freely rotate about said passage axis while substantially restricting axial displacement of said jounce bumper assembly relative to said piston assembly during said rotation. |
