摘要： A single axle suspension system including right and left dampers, first and second hydraulic circuits, one or more pressurizing mechanisms with a variable volume chamber that is connected in fluid communication with the first or second hydraulic circuits, and a bi-directional pump with a first impeller that is arranged in fluid communication with the first hydraulic circuit, a second impeller that is arranged in fluid communication with the second hydraulic circuit, and a motor that is configured to drive rotation of the first and second impellers to simultaneously pump the hydraulic fluid through the first and second hydraulic circuits in opposite directions. Each pressurizing mechanism includes a driven piston that is moveable in first and second directions to increase and decrease the volume of the variable volume chamber and therefore increase and decrease static pressure within the first and/or second hydraulic circuits independent of damper movements.

摘要： A motion sickness control system for a vehicle includes a vibrator. The motion sickness control system includes a sensor configured to measure vibration of the vehicle. The motion sickness control system includes a computer having a processor and a memory storing instructions executable by the processor to actuate the vibrator at a target frequency based on the measured vibration of the vehicle. The target frequency attenuates the measured vibration of the vehicle.

摘要： An air suspension system according to the principles of the present disclosure includes a suspension actuator, a reservoir, a compressor, and a first cooling circuit. The suspension actuator has a chamber. The reservoir includes a shell and an adsorptive material. The shell at least partially defines an interior region. The interior region is fluidly connected to the chamber. The adsorptive material is in the interior region. The compressor is fluidly connected to the interior region. The first cooling circuit includes a first heat exchanger, a second heat exchanger, and a conduit. The first heat exchanger is in thermal contact with the interior region. The second heat exchanger is in thermal contact with an electric vehicle component. The conduit is adapted to circulate a fluid between the first heat exchanger and the second heat exchanger. The present disclosure also provides a method of operating the air suspension system.

摘要： A shock absorber having a metal damper tube and base assembly is provided. The base assembly, which includes a composite mounting attachment made of a composite material, such as a recyclable thermoplastic, is fixed to an external surface of the metal damper tube, which may be a finished product. A cavity in the composite mounting attachment houses at least a portion of the metal damper tube and thus defines an overlapping region where the composite mounting attachment and the metal damper tube are co-extensive with each other. One or more windows are provided in the overlapping region of the composite mounting attachment where the metal damper tube is left exposed. This helps to promote heat dissipation away from the metal damper tube while reducing weight and heat transmission from the metal damper tube to the composite mounting attachment to reduce overheating of the composite material.

摘要： A single axle suspension system that includes right and left dampers, first and second hydraulic circuits, a first pressurizing mechanism that is connected in fluid communication with the first hydraulic circuit, and a second pressurizing mechanism that is connected in fluid communication with the second hydraulic circuit. The first and second pressurizing mechanisms are configured to provide active roll control by adding and removing hydraulic fluid to and from the first and second hydraulic circuits to increase and decrease pressure inside the first and second hydraulic circuits independent of damper movements. This in turn causes a simultaneous increase in the fluid pressure inside either the first working chamber of the right and the second working chamber of the left damper or the first working chamber of the left damper and the second working chambers of the right damper to provide roll stiffness that counters vehicle roll during cornering.

摘要： A suspension control system including a suspension control unit, an unsprung mass accelerometer positioned at each wheel of the vehicle, and a global positioning system. The suspension control unit determines if a road irregularity, such as a bump or pothole, is approaching based on vehicle location data, provides pre-emptive road event classification information for the approaching road irregularity, and sets both a threshold based suspension pre-setting and a threshold based pre-trigger based on the pre-emptive road event classification information. The suspension control unit monitors the unsprung mass acceleration data, calculates a slope value for the unsprung mass acceleration data, and activates a suspension control action if the unsprung mass acceleration data exceeds the threshold based pre-trigger and the slope value exceeds a maximum slope value.

摘要： An air-spring assembly includes a flexible bellows extending from a top end to a bottom end and enclosing an air-spring chamber between the top end and the bottom end, a first panel partially defining the air-spring chamber and movable in response to a pressure of the air-spring chamber, an enclosure partially defining a working chamber fluidly isolated from the air-spring chamber, a second panel partially defining the working chamber and movable relative to the enclosure, and a linkage member fixed relative to the first panel and to the second panel and defining a fixed distance between the first panel and the second panel. The top and bottom ends are fixable to a frame and a wheel of a vehicle, respectively. A volume of the air-spring chamber varies with movement of the bottom end relative to the top end. Movement of the second panel changes a volume of the working chamber.
