Clamping ring set for attaching e.g. hose to fastening area of pneumatic spring cover in motor vehicle, has contact, holding and tapered rings pretensioned so that diameters of tapered and contact rings are changed for pretensioning bellows

摘要

The set (1) has a contact ring (4) pressed at a hose or bellows i.e. pneumatic spring bellows (2), during pretensioning. A tapered ring (6) is arranged between the contact ring and a holding ring (5), whose cylindrical side surface is formed as a joining bevel (7). The tapered ring includes segments, whose joining bevels (11) are complementary to the bevels of the holding ring. The contact, holding and tapered rings are pretensioned with one another over the bevels so that diameters of the tapered and contact rings are changed for pretensioning the bellows. The contact ring is made of plastic.
