Document Type and Number:
WIPO Patent Application WO/2017/018130
Kind Code:
A1
Abstract:
[Problem] To provide, for example, a suspension device that enhances roll rigidity without deteriorating the durability of sealing or riding comfort of a vehicle. [Solution] A suspension device (1) according to the present invention is provided with: a pair of hydraulic dampers (DL) and (DR); a first flow path (P1) which communicatively connects an expansion-side chamber (EL) to a compression-side chamber (CR); a second flow path (P2) which communicatively connects a compression-side chamber (CL) to an expansion-side chamber (ER); and accumulators (AL) and (AR). Each of the accumulators (AL) and (AR) has: a casing (10); a first free piston (11) which partitions off an air chamber (G) inside the casing (10); and a second free piston (12) which partitions the air chamber (G) into a first air chamber (G1) and a second air chamber (G2). On the second free piston (12), the pressure-receiving area on the first air chamber (G1) side is set to be smaller than the pressure-receiving area on the second air chamber (G2) side.
