Abstract
An air spring including a spring seat, and a flexible sleeve connected to the spring seat. The flexible sleeve forms a compression chamber and includes a lobe that rolls along a surface of the spring seat during compression of the flexible sleeve. An annular barrier is disposed on the spring seat between the lobe of the flexible sleeve and the surface of the spring seat to deflect debris and ice from becoming lodged or trapped in the spring seat that may damage the flexible sleeve.
