Abstract: A damper assembly includes a damper with a pressure tube and a piston slidably disposed within the pressure tube. A first working chamber is defined on one side of the piston and a second working chamber is defined on an opposite side of the piston such that a volume of the second working chamber decreases during a compression stroke of the piston and the volume of the second working chamber increases during a rebound stroke of the piston. A bellow accumulator assembly is included and in fluid communication with the second working chamber. The bellow accumulator assembly includes a housing, a bellow accumulator disposed within the housing, a pressurized gas chamber defined between the housing and the bellow accumulator and an accumulator chamber defined between the bellow accumulator and the second working chamber.

Abstract: A suspension system including four dampers is disclosed where each damper includes a compression chamber and a rebound chamber. A first hydraulic circuit includes a front hydraulic line, a rear hydraulic line, and a first longitudinal hydraulic line that extends between and fluidly connects the front and rear hydraulic lines of the first hydraulic circuit. A second hydraulic circuit includes a front hydraulic line, a rear hydraulic line, and a second longitudinal hydraulic line that extends between and fluidly connects the front and rear hydraulic lines of the second hydraulic circuit. First and second longitudinal comfort valves are positioned in the first and second longitudinal hydraulic lines, respectively, between the front and rear hydraulic lines. Both of the first and second longitudinal comfort valves are electromechanical valves and can be actuated to couple and decouple front axle roll control from rear axle roll control.

Abstract: A shock for a vehicle includes a tube elongated along an axis. A piston is disposed in the tube and is moveable relative to the tube along the axis. A rod is connected to the piston. A floating piston is spaced from the piston along the axis and is moveable relative to the tube along the axis. The tube defines a working chamber between the piston and the floating piston. The tube defines a gas chamber. The floating piston separates the gas chamber from the working chamber. The floating piston has a housing slideably engaged with the tube and a membrane fluidly separating the working chamber from the gas chamber. The membrane is flexible relative to the housing.

Abstract: A damper including inner and outer tubes and a control valve. A piston is slidably disposed within the inner tube to define first and second working chambers. An intermediate member assembly is disposed annularly about the inner tube. An intermediate channel is positioned radially between the intermediate member assembly and the inner tube and a reservoir channel is positioned radially between the intermediate member assembly and the outer tube. A first unidirectional blocking valve forms a first partition between first and second intermediate channel portions of the intermediate channel. A second unidirectional blocking valve forms a second partition between the second intermediate channel portion and a third intermediate channel portion. An external control valve has a control valve inlet that is arranged in fluid communication with the second intermediate channel portion.

Abstract: A method for assembling a damper assembly includes securing a damper interface to an external surface of a pressure tube. The method includes securing an accumulator interface to an external surface of an accumulator tube. The method includes, after the damper interface is secured to the pressure tube and the accumulator interface is secured to the accumulator tube, securing the pressure tube to the accumulator tube by press fitting the damper interface to the accumulator interface.

Abstract: A damper assembly includes a rod elongated along an axis. The damper assembly includes a body supported by the rod, the body having a first surface and a second surface opposite the first surface. The body and the rod define a passage between the body and the rod, the passage extending from the first surface of the body to the second surface of the body.

Abstract: A damper includes a damper tube (a pressure tube or a reserve tube for a mono-tube or a double tube damper respectively) including a first end and a second end opposite to the first end. The damper includes a base member. The base member includes a cup portion at least partially enclosing the first end of the damper tube, and a sleeve portion extending from and integral with the cup portion. The sleeve portion surrounds a length of the damper tube. The sleeve portion is attached to the damper tube. Further, the damper includes a knuckle engaged with the sleeve portion such that the sleeve portion is disposed between the knuckle and the damper tube.

Abstract: A damper having a pressure tube, a piston, a hydraulic compression stop assembly, and a base valve assembly is provided. The piston is arranged in sliding engagement inside the pressure tube and divides the pressure tube into first and second working chambers. The hydraulic compression stop assembly is positioned in the second working chamber and includes a sleeve and a plunger. The sleeve extends from the base valve assembly to define a sleeve cavity. The plunger extends from the piston and/or piston rod and is designed to slide into the sleeve cavity when the piston approaches a fully compressed position of the damper. The base valve assembly includes intake passageways and an intake valve. The intake valve is constructed as a one-way valve that permits fluid to flow in one direction into the sleeve cavity through the intake passageways.
