Abstract: A suspension system comprises first and second dampers including first and second compression and rebound chambers. A first hydraulic circuit includes a first hydraulic line fluidly connecting the first rebound chamber of the first damper and the second compression chamber of the second damper. A second hydraulic circuit includes a second hydraulic line fluidly connecting the first compression chamber of the first damper and the second rebound chamber of the second damper. A proportional pressure accumulator in fluid communication with at least one of the first and second hydraulic circuits includes an accumulation chamber, a pressurized gas chamber and a volume varying mechanism. The volume varying mechanism selectively varying a volume of the pressurized gas chamber to vary a pressure within the pressurized gas chamber and change a fluid pressure within at least one of the first and second hydraulic circuits.

Abstract: A bellows accumulator for a vehicle suspension system and related methods of operating the accumulator include inserting a bellows assembly within an outer shell. The bellows assembly includes an annular bellows wall defining a gas chamber of variable volume. An accumulation chamber is provided between the outer shell and the bellows assembly. The method includes operating a valve in fluid communication with the accumulation chamber in an open condition and a closed condition, filling the accumulation chamber with fluid prior to filling the gas chamber with pressurized gas, providing a pressure differential between the pressurized gas chamber and the accumulation chamber to extend the annular bellows wall and operate the valve in the closed condition. The method includes protecting the bellows wall during pre-charging of the pressurized gas chamber as well as during vehicle suspension operation by maintaining fluid between the outer shell and the annular bellows wall.

Abstract: A method of pressuring an accumulator including an end cap and a floating piston comprises positions the floating piston outside an inner volume of the end cap. Pressurized gas is supplied to the inner volume through an open end of the end cap. The floating piston is inserted through the open end and sealing engagement with the end cap to define a pressurized gas chamber within the end cap. The method further includes mechanically deforming the end cap to define a radially inwardly extending projection that restricts removal of the floating piston from the end cap.

Abstract: Hydraulic port protection plugs for insertion into hydraulic ports in a shock absorber to prevent contaminants from entering the shock absorber and residual oil from draining out through the hydraulic ports during storage, shipping, and handling of the shock absorber. The hydraulic port protection plugs comprise a tubular body and a pierceable seal that is configured to receive an inboard portion of a hydraulic fitting. The pierceable seal is designed so that the inboard portion of the hydraulic fitting may be inserted through the pierceable seal of the hydraulic port protection plug and into the hydraulic port in the shock absorber such that the hydraulic port protection plug does not have to be removed and seals the hydraulic fitting within the hydraulic port in the shock absorber in an installed position.

Abstract: A method of forming a dirt shield on a shock absorber includes positioning a mold over a portion of the shock absorber, heat shrinking a sleeve onto the mold, and removing the mold from the portion of the shock absorber such that the sleeve after heat shrinking remains on the shock absorber and forms the dirt shield. The shock absorber includes a piston rod, a mount rigidly attached to the piston rod, and a bushing secured to the mount. Prior to heat shrinking the sleeve, the sleeve slides over the bushing, and after heat shrinking the sleeve the bushing has an outer dimension greater than an inner dimension of the dirt shield. Also, a plurality of sleeves having the same inner dimension is used to form a plurality of dirt shields having different inner dimensions.
