AIR SPRING WITH CONSTRAINED ELASTIC SLEEVE

摘要

An air spring (10) comprises a hollow elastic sleeve (12), an upper component (22) for securing the air spring to a first frame, a hollow piston (14) for securing the air spring (10) to a second frame that is movable relative to the first frame, and a cylinder (16) surrounding the hollow elastic sleeve to constrain the diameter of the hollow sleeve (12) and reduce the effective area of the air spring to reduce the natural frequency of the air spring (10).
