ABSTRACT:
An air spring for motor vehicles which includes first and second axially spaced piston members with an intervening flexible sleeve forming a fluid pressure chamber therebetween sealingly connected to the piston members. The sleeve has a greater axial length than the at-rest spacing between the piston members resulting in opposed rolled sleeve ends. The rolled sleeve ends extend about an annular-shaped member which surrounds the first piston members when in the at-rest position. The second piston member has an annular-shaped outer wall which extends telescopically about the first piston member and within the other annular-shaped member thereof when the air spring is in a collapsed or jounce position with the rolled ends forming about and within the annular-shaped members of the first piston member and outer wall of the second piston member. The rolled ends of the sleeve unroll to provide increased axial length to the sleeve enabling the piston members to move axially apart beyond the at-rest position and into an extended position providing an air spring with a large stroke with a minimum at-rest height.
