Various embodiments related to hydraulic actuators and active suspension systems as well as their methods of use are described.

A shock absorber includes a gas spring cylinder containing a piston moveable between an extended position and a compressed position within the gas spring cylinder. A mechanical actuator is arranged whereby a bleed port is automatically closed when the gas spring is compressed to a predetermined position corresponding to a desired sag setting. In one embodiment, the position corresponds to a predetermined sag setting whereby the gas spring is partially compressed. In another embodiment, a proper sag setting is determined through the use of a processor and sensor that in one instance measure a position of shock absorber components to dictate a proper sag setting and in another instance calculate a pressure corresponding to a preferred sag setting.

A suspension system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.

A decoupling bearing for a suspension strut or a pneumatic suspension strut may include a suspension strut cup and a connecting element that can be connected to a vehicle body. A damping element may be arranged between the suspension strut cup and the connecting element. The suspension strut cup may be connected to the connecting element by the damping element. Further, the damping element may be adhesively bonded to the connecting element and the suspension strut cup in a force-transmitting manner, and/or the damping element may be adhesively bonded to the connecting element and an intermediate element in a force-transmitting manner. The intermediate element may be connected to the suspension strut cup.
