A coil spring assembly is disclosed for use with motor vehicle suspension systems in which a portion of the wire coils of the coil spring is covered by a flexible hose or tube. Coil springs which could use such hoses include those having a tapered wire diameter wherein one end of the coil spring's wire has a smaller diameter than at other portions of its length. The flexible hose is made of a material which has sufficient resiliency to first be stretched as it is installed onto the wire of the coil spring, and then will naturally return back to near its original non-stressed diameter to tightly fit around thediameter of the wire at both ends of the hose. The resulting tight fit retains lubricant and anti-corrosive compounds inside the hose, and keeps moisture and dirt from entering the interior of the hose.
ssemblage de ressort hélicoïdal pour suspensions de véhicules automobiles. Une partie des ressorts de l'assemblage est recouverte d'un boyau ou d'un tube flexibles. Les ressorts pouvant être munis de tels boyaux comprennent notamment les ressorts effilés, dont le fil de fer, à une des extrémités, est de diamètre inférieur au reste du fil. Le boyau flexible est fabriqué d'un matériau suffisamment élastique pour être d'abord étiré sur le fil du ressort hélicoïdal au moment de l'installation, et ensuite reprendre automatiquement et presque intégralement son diamètre initial afin que les deux extrémités du boyau épousent sans jeu le diamètre du fil de fer. Cet ajustement serré permet de retenir des lubrifiants et des composés anticorrosifs à l'intérieur du boyau et empêche l'humidité et la saleté de pénétrer.
