Air spring for motor vehicle, has cover, rolling piston, bellow mounted at cover and at rolling piston, and outer guide, where bellow has inner layer and outer layer

摘要

#CMT# #/CMT# The air spring (2) has a cover (4), a rolling piston (6), a bellow (8) mounted at the cover and at the rolling piston, and an outer guide. The bellow has an inner layer (14) and an outer layer (16). The inner layer and the outer layer are connected firmly in an area of the bellow, which is facing the cover of the air spring. The inner layer and the outer layer are separated from each other in another area of the bellow, which is facing the rolling piston. The end of the inner layer is connected with the rolling piston for forming a rolling area. The outer layer is provided as outer guide. #CMT# : #/CMT# An independent claim is included for a method for manufacturing a bellows. #CMT#USE : #/CMT# Air spring for a motor vehicle. #CMT#ADVANTAGE : #/CMT# The air spring has a cover, a rolling piston, a bellow mounted at the cover and at the rolling piston, and an outer guide, where the bellow has an inner layer and an outer layer, and thus a simple and cost-effective manufacturing of the air spring is ensured. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an air spring. 2 : Air spring 4 : Cover 6 : Rolling piston 8 : Bellow 14 : Inner layer 16 : Outer layer.
