Rolling bellow for pneumatic spring, has sealing ring connected with bellow over bar, where sealing ring rests in fastening region against connectors under pressure seal and end side peripheries of bellow are vulcanized

摘要

The bellow (1) has connectors partly rolling on rolling contours and secured at ends of the counters. End side peripheries (2, 2') of the bellow are vulcanized. A sealing ring (4) is connected with the bellow over a bar (3), where the sealing ring rests in a fastening region against the connectors under a pressure seal. The sealing ring and the bar are connected with the bellow during vulcanization process of the bellow, where the sealing ring is provided with an O ring. An independent claim is also included for a method for manufacturing a rolling bellow.
