    Abstract: The present disclosure relates to a coil assembly for an actively controlled damping valve assembly of a vehicle, comprising: a mating surface for mating with an inner surface of a cavity of a valve housing of the damping valve assembly, and a fixation member configured for axially and rotationally locking the coil assembly with said valve housing, wherein the fixation member is adapted with an outer surface of substantially circular geometry comprising two or more protuberances circumferentially spaced apart and defining press-fit interference points with the inner surface of the cavity such that the coil assembly is axially and rotationally lockable to the valve housing irrespective whether the coil assembly is inserted into the valve housing in a first axial rotational orientation or an at least second axial rotational orientation relative the valve housing different from the first axial rotational orientation. An actively controlled damping valve assembly or a vehicle and a method of mounting the coil assembly in such damping valve assembly is also disclosed.

    Abstract: A suspension system including hydraulic circuits that extend between dampers located at opposite corners of the vehicle and at least one load distribution unit that is connected in fluid communication with at least two hydraulic circuits. The load distribution unit includes a manifold block with a cylinder bore, a pair of pressure tubes, a piston rod assembly, and an integral rod guide and pressure tube coupler. The pressure tubes are partially received in the cylinder bore to define a pair of opposed cylinders and mate with the integral rod guide and pressure tube coupler. The piston rod assembly includes a piston rod and a pair of opposed pistons that are slidingly received within the opposed cylinders. In addition to retaining the pressure tubes, the integral rod guide and pressure tube coupler supports and permits the piston rod to slide longitudinally relative to the manifold block.

    Abstract: A single axle suspension system including right and left dampers, first and second hydraulic circuits, one or more pressurizing mechanisms with a variable volume chamber that is connected in fluid communication with the first or second hydraulic circuits, and a bi-directional pump with a first impeller that is arranged in fluid communication with the first hydraulic circuit, a second impeller that is arranged in fluid communication with the second hydraulic circuit, and a motor that is configured to drive rotation of the first and second impellers to simultaneously pump the hydraulic fluid through the first and second hydraulic circuits in opposite directions. Each pressurizing mechanism includes a driven piston that is moveable in first and second directions to increase and decrease the volume of the variable volume chamber and therefore increase and decrease static pressure within the first and/or second hydraulic circuits independent of damper movements.

    Abstract: A baffle press-fit against an inner portion of an outer tube defining an interior of a hydraulic damper. The baffle comprising a first wall, a second wall, opposite the first wall, a circumferential third wall, and a channel formed between at least a portion of the circumferential third wall and the inner portion of the outer tube. The channel comprising an inlet formed along at least a portion of the first wall, an outlet formed along at least a portion of the second wall, and a groove formed along at least a portion of the circumferential third wall and fluidly coupling the inlet to the outlet.

    Abstract: A damper comprises an inner tube having a longitudinal axis with a piston slidably disposed in the inner tube. An outer tube surrounds the inner tube and defines a fluid chamber therebetween. A first valve assembly includes a first valve ring and a first valve disc fixed to the first valve ring. The first valve disc covers a first passageway to restrict flow therethrough in a first direction and allow flow in an opposite second direction. A second valve assembly includes a second valve ring and a second valve disc fixed to the second valve ring. The second valve disc covers a second passageway through the second valve ring to restrict flow therethrough in the second direction and allow flow in the first direction. The first valve assembly is axially spaced apart from the second valve assembly.

    Abstract: A damper with a pressure tube and an outer tube, a piston rod extending between first and second piston rod ends, and a piston mounted to the second piston rod end. The piston is disposed within the pressure tube to define rebound and compression chambers. A reservoir chamber is positioned between the pressure tube and the outer tube and an intake valve assembly, abutting one end of the pressure tube inside the outer tube, defines at least one intermediate chamber that is arranged in fluid communication with at least one externally mounted, electro-mechanical control valve. A rebound chamber pressure relief valve, in the form of a poppet positioned inside the piston and piston rod end, releases excess fluid pressure in the rebound chamber. A compression chamber pressure relief valve, in the form of a poppet positioned inside the intake valve assembly, releases excess fluid pressure in the compression chamber.
