  • Patent number: 6978872
    Abstract: A suspension damper includes a housing bounding a main chamber. A piston rod is slideably disposed within the main chamber of the housing. A main piston is mounted on the first end of the piston rod within the main chamber of the housing so as to slideably engage against the housing in sealed engagement, the main piston having a first side and an opposing second side with a compression port extending therebetween. A control valve assembly is disposed within the main chamber and bounds a sealed valve compartment. The control valve assembly is movable between a first position wherein the valve compartment is compressed to a first volume and a second position wherein the valve compartment is expanded to an enlarged second volume, the control valve assembly being movable under pressure so as to provide variable compression damping properties.

  • Patent number: 6585223
    Abstract: A bushing for use in a vehicle suspension system includes a pair of elastomeric bearings having cylindrical holes formed therein and flanges formed integrally therewith. The bushing further includes a journal carried by the bearings in the cylindrical holes. In the first embodiment, the bearings are of substantially elliptical cross section and provide a compliance in a major axis direction that is different than the compliance in a minor axis direction. In a second embodiment, the bearings additionally are formed with channels of partial substantially cylindrical section on the outer surfaces, thereby giving the bearings a compliance in the major axis direction of a nonlinear higher order than the corresponding compliance of the first embodiment. A third embodiment is similar to the second embodiment except that the bearings are formed with voids of a partial substantially conic section formed on the outer surface, with the apex of the voids being adjacent the flanges.

  • Patent number: 5548898
    Abstract: 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 the diameter 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.
