Abstract:
A suspension apparatus comprising a pair of hydraulic dampers disposed on left and right sides of a vehicle, an upper end side of which is connected to a vehicle body side and a lower end side is connected to an axle side, and a pressure regulating cylinder communicating with piston side oil chambers of the pair of hydraulic dampers, wherein the pressure regulating cylinder has a free piston slidably disposed within a cylinder body and defining a front side chamber and a back side chamber within the cylinder body, the free piston being slidably encased in a cylinder member and having a partitioning member for defining a closed chamber and an open chamber communicating with a front side chamber on the inner peripheral side of the free piston, the partitioning member having a damping valve which enables communication between the closed chamber and the open chamber and having a proximal end connected to an extreme end of a rod body elastically supported on the cylinder body, the front side chamber being caused to communicate with a piston side oil chamber of one hydraulic damper, and the closed chamber being caused to communicate with a piston side oil chamber of the other hydraulic damper through a through-hole bored in an axial part of the rod body.
