Abstract
An air spring includes a flexible member which, on the one hand, is attached to a housing and, on the other hand, to a roll-off piston and which encloses an air volume. The surface of the housing, which faces toward the air volume of the air spring, is charged with the air pressure of the air volume; and, the air spring can be connected to the chassis of a motor vehicle with the interposition of an elastic bearing. The housing includes at least two parts of which a first part serves as the connection of the air spring to the chassis of a motor vehicle and a second part serves as the attachment of the flexible member; and, the elastic bearing is configured to have an annular shape and is mounted between the two parts of the housing.
