摘要

The air spring has a shock absorber which passes through the top of the piston. The bellows is fastened to the top of the piston by a ring clip and a locking ring fits over this. The locking ring consists of an inner (18) and outer (22) ring, the inner ring having a collar (19) which fits over the rim of the piston and a resilient arm (20) which caries a hook (21) at its base. The inner ring has a section (23), which fits outside the resilient arm and also carries a hook (25) at its base, and a second section (24) through which the shock absorber passes. These retain the arm between them, forming a snap fitting with the first hook.
