    摘要： A vehicle includes a suspension system having a first damper, a second damper, valves and a controller. Each of the first damper and the second damper include a housing and a piston sealingly interfaced with an inner diameter of the housing, dividing the damper into a first and second chamber. Each valve controls flow rate of fluid entering or exiting at least one of the first and second chamber of at least one of the first damper and the second damper. The controller controls the valves to control extension or compression of at least one of the first damper and the second damper based on at least one of a degree of roll of the vehicle during a turn of the vehicle and a degree of pitch of the vehicle during acceleration of the vehicle or a degree of pitch of the vehicle during deceleration of the vehicle.

    摘要： A pump includes a housing defining an interior volume, a diaphragm partitioning the interior volume into a pumping chamber and an actuating chamber, a diaphragm support associated with the actuating chamber and configured to limit movement of the diaphragm, and a dispersion element coupled to the housing. The dispersion element includes a network of channels that is configured to distribute a fluid within the pump.

    摘要： A vehicle includes a suspension system having a first damper, a second damper, and a controller. The dampers include housings and pistons sealingly interfaced with an inner diameter of the housing, dividing the damper into a first and second chamber. The suspension system includes proportional variable relief valves which control pressure of fluid entering or exiting one of the first and second chamber of one of the first and second damper. The controller controls the valves to control extension or compression of the first damper and extension or compression of the second damper based on a degree of roll of the vehicle during a turn of the vehicle or a degree of pitch of the vehicle during acceleration or deceleration of the vehicle. The first and second damper control a roll and pitch of the vehicle. The valves control a damping rate of one of the first and second damper.

    摘要： A gas spring for a vehicle suspension system includes a cylinder, a rod disposed within the cylinder, a relative movement between the rod and the cylinder changing the volume of a chamber formed between the rod and the cylinder, and an accumulator in communication with the chamber. Compression of gas in the chamber at least partially provides a first spring rate for deflections of the gas spring below a threshold, compression of gas in the chamber at least partially provides a second spring rate for deflections of the gas spring above the threshold, and the first spring rate is greater than the second spring rate.

    摘要： A damper assembly for a vehicle suspension system includes a primary damper and a secondary damper. The secondary damper is coupled to the primary damper and includes a housing and an annular piston. The housing includes a sidewall that partially surrounds the primary damper, and the volume between the sidewall and the primary damper defines a damping chamber. The sidewall defines a plurality of apertures. The annular piston is positioned within the damping chamber and slidably coupled to the sidewall. The primary damper provides a base damping force and the secondary damper provides a supplemental damping force that varies based on the position of the annular piston along the housing.
