A suspension system may include a pneumatic spring at each wheel of a vehicle. The suspension system may be configured to determine and achieve a pressure set point in each of the pneumatic springs and a target ride height at each wheel of the vehicle. The pressure set point may be determined based on a load at each of the wheels and the center of gravity of the vehicle, such that upon reaching the pressure set point at each in each of the pneumatic springs, a target load and target ride height may be achieved at each of the wheels of the vehicle. The system may also be used to level the ride height of the vehicle and/or achieve a desired orientation.

A suspension system for a vehicle is provided. The system utilizes pistons, one on each side of the vehicle, engaged with a vehicle body at a distal end and having a fluid chamber at the proximal end. The system further has a central chamber having a rod freely laterally moving therein. A fluid communicates between the central chamber and each piston fluid chamber. Upon nonlinear forces applied to the vehicle, the rod is urged in one direction or another. This urging applies force to the fluid in the central chamber, and in turn, to the piston in the corresponding side of the vehicle, urging the piston up and in turn urging the vehicle body up.

A damping force control apparatus for a vehicle in which road surface displacement-related information corresponding to left and right wheels detected by a pair of in-vehicle detection devices is transmitted to a preview reference database control device together with the detection position information, a preview reference database including road surface displacement-related values is created, preview damping control that reduces vibration of a sprung of the vehicle is performed using the road surface displacement-related values in the preview reference database, and it is assumed that road surface displacement-related values in predetermined adjacent regions located in a direction crossing a traveling direction of the vehicle with respect to two points where the road surface displacement-related information was detected by the pair of in-vehicle detection devices are the same as an in-phase component of the road surface displacement-related values at the two points.

A damper assembly for a vehicle suspension system includes a first damper and a second damper. The second damper includes a housing having a wall that at least partially surrounds at least a portion of the first damper, the volume between the wall and the first damper defining a chamber, and the wall defines an aperture. The second damper also includes a piston positioned within the chamber, a conduit defining a flow path that includes the aperture, and a flow control device disposed along the flow path. The second damper is configured to provide a damping force that varies based on the position of the piston within the chamber.

A liquid gas supporting shock absorber. An oil path of the liquid gas supporting shock absorber, mainly composed of a liquid gas accumulator (4) and a single-acting hydraulic cylinder (7), is divided into a liquid inlet oil path (9) flowing into the single-acting hydraulic cylinder (7) and a liquid outlet oil path (6) flowing out of the single-acting hydraulic cylinder (7). A supporting force value of the liquid gas supporting shock absorber on an item supported thereby is measured using a force measuring element. A control component (1) compares the supporting force value to a set force value or a gravity value of the item supported by the supporting shock absorber, and the damping of the liquid inlet oil path (9) and the liquid outlet oil path (6) of the liquid gas supporting shock absorber is controlled by means of a mechanical, hydraulic or electronic control mode according to the result of the comparison, so as to adjust the supporting force value of the supporting shock absorber, so that the supporting force value of the supporting shock absorber is equal to or close to the set force value or the gravity value of the item supported by the supporting shock absorber.

Techniques regarding a vehicle suspension assembly are provided herein. For example, one or more embodiments described herein can regard an apparatus that can comprise a locking plate that can be located between a first spring and a second spring in a first direction. Also, the locking plate can comprise a locking pin. Moreover, the apparatus can comprise a locking sleeve that can surround the first spring and the locking plate. The locking sleeve can comprise a first channel that traverses the locking sleeve in the first direction. The locking sleeve can further comprise a second channel that is connected to the first channel and traverses the locking sleeve in a second direction.

Presented herein, inter alia, are suspension system components having tuned accumulator sizing and/or stiffness. Such suspension system components are envisioned for use in a distributed active suspension system of a vehicle. In particular, through appropriate sizing of accumulators of a suspension system component of a vehicle, ride quality of the vehicle may be improved and so called “rough ride” issues may be precluded. Alternatively or additionally, various valves or alternative compliant mechanisms may be included in the suspension system component, so that desirable performance may be obtained for a range of operating conditions.

A hydraulic suspension system for a motor vehicle having at least a pair of road engaging wheels.

A hydraulic supply circuit for the hydraulic cylinder includes, a high pressure hydraulic source, a low pressure hydraulic drain, a pair of hydraulic sub circuits each coupled to one of the hydraulic cylinder cap and rod end volumes. Each hydraulic sub circuit includes, a proportional supply flow valve coupled with the high pressure hydraulic source and one of the cylinder volumes, a return flow control proportional valve coupled with the low pressure hydraulic drain and the one cylinder volume, and an accumulator coupled to the associated hydraulic cylinder volume through an accumulator fill control proportional valve.
