Abstract
An air spring comprises a hollow elastic sleeve, an end component for securing the air spring to a first frame, a hollow piston for securing the air spring to a second frame that is movable relative to the first frame, and a cylinder surrounding the hollow elastic sleeve to constrain the diameter of the hollow sleeve. A meniscus loop is formed adjacent the piston to define a major diameter of the air spring and thereby reduce the natural frequency of the air spring.
