BPW air bags are firmly rolled into the flange of the upper air bag cover and vulcanised with the clamping plate at the bottom. The upper air bag cover is either directly bolted to the bottom flange of the frame or a plate or mounting bracket is welded to the vehicle frame for fixing – depending on the air bag design. The air bag cover is fixed to it using two M 12 self-locking nuts. The lower air spring piston is bolted to the trailing arm using two M 16 self-locking nuts.
