摘要： A suspension system (S) according to the present invention is configured to control actuators (A FR , A FL , A RR , A RL ) by determining a pitch damping force (F P ) and a roll damping force F R ) to cancel roll and pitch moments (M P , M R ) of a body (B), and determining target control forces (F TFR , F TFL , F TRR , F TRL ) in consideration of the pitch damping force (F P ) and the roll damping force F R ). When the pitch damping force (F P ) and the roll damping force (F R ) are output to the actuators (A FR , A FL , A RR , A RL ), the actuators (A FR , A FL , A RR , A RL ) can each generate a control force for cancelling a force acting on the body (B) not later but preliminarily.

摘要： A shock absorber (D1) includes a suction passage (3) that only allows a flow from a reservoir (R) towards a pressure side chamber (R2), a rectifying passage (4) that only allows a flow from the pressure side chamber (R2) towards an expansion side chamber (R1), and a damping force variable valve (V) that only allows a flow from the expansion side chamber (R1) towards the reservoir (R). A large chamber (16) serving as a pressure-side pressure chamber, which communicates with the pressure side chamber (R2), and an outer peripheral chamber (17) serving as an expansion-side pressure chamber, which communicates with the expansion side chamber (R1), are provided so as to sandwich a free piston (5) that slidably moves within a bottom member (11) serving as a housing forming a pressure chamber (14). Because a pressure-side pressure-receiving area (A1) of the free piston (5) is larger than an expansion-side pressure-receiving area (B1), at the time of a contraction operation in which a piston (2) moves downward, the free piston (5) can move downward even in a uniflow-type shock absorber in which pressure in the expansion side chamber (R1) becomes equal to that in the pressure side chamber (R2), and thereby, damping force can be reduced at the time of input of high-frequency vibration.

摘要： A shock absorber includes a suction passage (3) configured to permit only a flow from a reservoir (R) toward a compression-side chamber (R2), a rectification passage (4) configured to permit only a flow from the compression-side chamber (R2) toward a extension-side chamber (R1), and a variable valve (V) configured to permit only a flow from the extension-side chamber (R1) toward the reservoir (R). A large chamber (16) serving as a compression-side pressure chamber that communicates with the compression-side chamber (R2) and an outer periphery chamber (17) serving as a extension-side pressure chamber that communicates with the extension-side chamber (R1) are partitioned in the shock absorber by a free piston (5) that moves slidably within a bottom member (11) serving as a housing. A compression-side pressure-receiving area (A1) of the free piston (5) is larger than an extension-side pressure-receiving area (B1). Therefore, even in the uniflow shock absorber in which the extension-side chamber (R1) and the compression-side chamber (R2) are at equal pressures during the contraction operation, the damping force is reduced under conditions in which high frequency is input since the free piston (5) moves downward.
