Abstract
An air spring with a pair of spaced end members and a flexible elastomeric sleeve forming a pressurized chamber in combination with the end members is disclosed. The air spring is provided with an internal bumper to absorb impacts and prevent collapse of the air spring when in operation. The bumper is formed with a continuous ledge in the central opening. Securing the bumper to one of the end members is a hollow cup. The cup lip engages the bumper ledge and the cup is attached to the end member.
