Pressurizable component assembly for use in tubular rolling-lobe pneumatic spring that is utilized as suspension unit in motor vehicle, has elastomer component comprising rubber composition layers with different compression sets
The assembly has a connection part (1) clamped with a tubular elastomer component i.e. tubular rolling-lobe (4), by a clamping unit (3) in a clamping region (2). The elastomer component comprises two rubber composition layers (9, 10) with different compression sets according to DIN 53 517in the clamping region. One of the rubber composition layers with the higher compression set is partially arranged in a region of elevations (5) of a clamping contour. The other rubber composition layer with lower compression set is arranged in an end region of the elastomer component.
