The cross-ply bellows mainly used on the rear axle uses two layers of intersecting reinforcement carriers (fibers) in the bellows wall. These are covered inside and out with a sealing or protective elastomer layer. There is another elastomer layer, the intermediate layer, between the two layers of threads. The intermediate layer defines the geometrical cohesion of the two layers of threads. With a cross-ply bellows, the pressure resilience is defined by the stability carrier, while the material properties of the intermediate layer influence the service life and comfort. The advantages of the cross-ply bellows are its high-pressure resistance and dimensional stability, along with relatively simple and process-assured production.
