Air spring for motor vehicle, has rolling pistons telescopically sliding into one another by movement in compression and decompression directions, where one rolling piston is arranged coaxial to another rolling piston

摘要

The spring (10) has a rolling piston (24) completely enclosing an axial rolling bellow (14) in a compression direction (ER) and a decompression direction (AR) and arranged such that an inner mantel surface forms an outer guide (36) for the bellow. The rolling piston and another rolling piston (32) telescopically slide into one another by a movement in the compression and decompression directions. The piston (32) is arranged coaxial to the piston (24). Buffer elements (42) are made of elastomer and arranged between a lower contact surface (38) and a contact flange (40) of the pistons.
