摘要： A suspension assembly between a sprung element and an unsprung element includes a load-carrying spring and a negative stiffness element between the sprung element and the unsprung element. The load-carrying spring element is configured with a positive spring rate to support a static load of the sprung element. The negative stiffness element is configured with a negative spring rate and is configured to exert a force opposing the spring rate of the spring, the negative spring rate has a magnitude that cancels the positive spring rate at a zero deflection point of the suspension assembly. The suspension assembly also includes an active trimming mechanism which is configured to move a plurality of pivot points of the negative stiffness element to achieve a trimmed position of the negative stiffness element.

摘要： A shock absorber includes a suction passage permitting flow only from a reservoir toward a compression-side chamber, a rectification passage permitting flow only from the compression-side chamber toward an extension-side chamber, and a variable valve permitting flow only from the extension-side chamber toward the reservoir. A large chamber as a compression-side pressure chamber communicating with the compression-side chamber and an outer periphery chamber as an extension-side pressure chamber communicating with the extension-side chamber are partitioned in the shock absorber by a free piston that moves slidably within a bottom member serving as a housing. A compression-side pressure-receiving area of the free piston is larger than an extension-side pressure-receiving area. Therefore, even in the uniflow shock absorber with the extension-side chamber and the compression-side chamber at equal pressures during the contraction operation, the damping force is reduced under conditions in which high frequency is input since the free piston moves downward.

摘要： A damper system and method for a vehicle includes a shock absorber and a damper module. The shock absorber includes a plurality of digital valves. The shock absorber is operable at one of multiple damping states based on a valve state of the digital valves. The damper module is coupled to each of the digital valves and controls each of the digital valves to a desired state based on a damper setting. The damper module determines a target damping state, where the target state is one of the multiple damping states. The damper module performs a switch operation to control the valve state of the plurality of digital valves to a given desired state when the target damping state is different from a present damping state.

摘要： A ride height control system and method may be used to control load distribution at wheel locations in a vehicle suspension system at target ride height. Load distribution may be controlled by adjusting the forces applied by the suspension system at respective wheel locations while maintaining a target ride height. In an exemplary air spring suspension system or hydropneumatic suspension system, the applied forces may be adjusted by adjusting the pressure in the suspension system at the respective wheel locations. The ride height control system and method may determine and establish balanced target ride height forces (e.g., planar forces) to be applied at the wheel locations of the vehicle to prevent a cross-jacking condition. The ride height control system and method may also determine and establish target ride height forces for a vehicle on an uneven surface to prevent imbalances caused by wheel displacement.
