Abstract: A valve assembly and a hydraulic circuit including the valve assembly are provided. The valve assembly comprises a hydraulically actuated valve configured to be biased from a first control position to a second control position by a hydraulic pressure applied to a first fluid port of the hydraulically actuated valve. A first switching threshold pressure required to switch the hydraulically actuated valve to its second control position when applied to the first fluid port of the hydraulically actuated valve in its first control position differs from a second switching threshold pressure required to keep the hydraulically actuated valve in its second control position when applied to the first fluid port of the hydraulically actuated valve in its second control position.

Abstract: Methods and systems for hydraulic vehicle suspension are provided. A hydraulic suspension system, in one example, includes a first manifold including a piston-side interface and a rod-side interface fluidically coupled to a piston chamber and a rod chamber, respectively, for each of a first hydraulic cylinder and a second hydraulic cylinder. In the system, the first manifold includes a first electrically activated valve fluidically coupled to the piston-side interfaces, a first damping device, and a second damping device, the first electrically activated valve is configured to lock and unlock vertical motion of the first and second hydraulic cylinders and, while vertical motion of the first and second hydraulic cylinders is locked, the first electrically activated valve permits fluidic communication between the first and second hydraulic cylinders to permit free roll motion in the hydraulic suspension system.

Abstract: A disconnector assembly for a wheel hub transmission where the wheel hub transmission may have an input shaft that receives an input torque from a drive unit. The disconnector assembly may have a first coupling portion driven by the input shaft, and a connector having a second coupling portion and being axially displaceable between a first axial position and a second axial position. Each of the first and second coupling portions may have at least two engagement sections and at least one disengagement section positioned between the engagement sections. The engagement sections of the first and second coupling portions may engage each other when the connector assumes the first axial position. When the connector assumes the second axial position, at least one engagement section of the first and second coupling portion may be received in the disengagement section of the respective other of the first and second coupling portion.
