Support unit for bellow, has support units provided for generating resetting forces in their mounting position through prestressing, where resetting forces brace and stabilize external folding of bellow against external forces

摘要

The unit has wire and circular ring-shaped support units (3) that are engaged into a folding base (g) of an external folding (11a) of a bellow (11) in a removable manner, where one of the support units is made from a spring wire and designed as a closed pressure spring. The support units generate resetting forces in their mounting position through prestressing, where the resetting forces brace and stabilize the external folding against the external forces.
