In a suspension system in which the oil chambers of two dampers are connected, the responsiveness of the dampers can be adjusted. A suspension system has a left damper, a right damper, and an intermediate unit. A case of the intermediate unit has an intermediate oil chamber connected to an oil chamber of the left damper and the oil chamber of the right damper and an intermediate gas chamber. The intermediate oil chamber and the intermediate gas chamber are partitioned by a diaphragm. The intermediate unit has a capacity adjustment mechanism including a movable portion of which the position can be changed. The capacity adjustment mechanism adjusts the capacity of the intermediate gas chamber by changing the position of the movable portion.

Provided is a suspension system capable of expanding one of an oil chamber and a gas chamber of an intermediate unit and contracting the other when a damper compresses or expands without generating friction in the intermediate unit. The intermediate unit includes an intermediate case having an intermediate oil chamber connected to an oil chamber of a right damper and the oil chamber of a left damper and an intermediate gas chamber, and a diaphragm made of a flexible material, which partitions the intermediate oil chamber and the intermediate gas chamber.

An anti-roll bar link for a vehicle suspension may be positioned between an anti-roll bar and an articulating arm. The link selectively transfers movement of the arm to the anti-roll bar, depending on a locked or unlocked state. The link includes a body interfacing a slidable shaft. A physical feature selectively locks or unlocks the slidable shaft with respect to the body. The physical feature may include a locking pin, interference with a locking ball, etc. In the locked state, translation of the slidable shaft is restricted, and movement of the arm is transferred through the link to the bar. In the unlocked state, translation of the slidable shaft is permitted, and movement of the arm causes the shaft to translate with respect to the body such that at least a portion of the movement is not transferred to the bar.

A suspension apparatus includes a pair of hydraulic cylinders and a valve device provided between an upper chamber and a lower chamber of each of the hydraulic cylinders and configured to establish and block communication between these chambers. The valve device includes a first passage and an extension-side damping force generation mechanism. Hydraulic oil flows out from the upper chamber into the first passage due to movement of a piston in a cylinder of the hydraulic cylinder. The extension-side damping force generation mechanism includes a damping valve and a back-pressure chamber. The damping valve is disposed in the first passage and generates a damping force by restricting a flow of the hydraulic oil generated due to a sliding movement of the piston. The back-pressure chamber applies an inner pressure thereof to the damping valve in a valve-closing direction.

The invention relates to a damper unit (10) for a chassis (100) of a vehicle with levelling, comprising a hydraulic cylinder (1) having a container tube (2) which is filled with a damper fluid and in which a piston (3) is movably mounted and separates an upper container space (21) from a lower container space (22). The piston (3) comprises a first valve (41) through which the damper fluid flows when the piston (3) moves in a first direction A. The damper unit (10) further comprises an accumulator (5) and a check valve (6), wherein the accumulator (5) is connected to the container tube (2) via the check valve (6) in such a manner that, when the piston (3) moves in at least one direction, damper fluid is pumped through the check valve (6) into the accumulator (5).

A vehicle stabilization system is disclosed which include two double-acting hydraulic cylinders of the same size, each attached to a vehicle, chassis and the wheel hub assembly on an axle, each cylinder having a top chamber and a bottom chamber, a hydraulic system which includes two compression chambers disposed between the two double acting cylinders, and hydraulic lines coupling the top chamber of one double-acting hydraulic cylinder to the bottom chamber of the other double-acting hydraulic cylinder, and vice versa, and to the two compression chambers disposed therebetween, movement of a first axel of a first chassis with respect to a second axel of the first chassis causes an increase in pressure in one of the two compression chambers and a decrease in pressure in the other of the two compression chambers, thereby providing a hydraulic coupling between the two axels.
