The suspension apparatus comprises a pair of hydraulic dampers (1) for mounting between the body and axle of a vehicle, and a pressure regulating cylinder (2) communicating with piston side oil chambers (a) of the hydraulic dampers (1). The pressure regulating cylinder (2) has a free piston (26) slidably disposed within a cylinder body (24) and defining a front side chamber (h) and a back side chamber (i). The free piston (26) contains a partitioning member (27) separating a closed chamber (j) from an open chamber (k) which communicates with the front side chamber (h). The partitioning member (27) also has a damping valve (4) which enables communication between the closed chamber (j) and the open chamber (k) and is connected to a rod body (29) elastically supported on the cylinder body (24). The front side chamber (h) communicates with the piston side oil chamber (a) of one of the hydraulic dampers (1), and the closed chamber (j) communicates with the piston side oil chamber (a) of the other hydraulic damper (1) through an axial through-hole (29b) of the rod body (29). Because the cylindrical sliding surfaces of the cylinder body (24) and free piston (26) do not have steps which vary their diameters along their lengths, the suspension apparatus is easy to manufacture and experiences reduced wear in use. <IMAGE> |
