切換機構。The figures show a suspension system for a vehicle as an embodiment of the present invention. Fig. 1 is a sectional view showing its overall configuration, and Fig. 2 is a state I in Fig. 1. They are a cross-sectional view taken along the I-I arrow, a cross-sectional view taken along the ■-n arrow, and a cross-sectional view taken along the ■-■ arrow.
"c" shows a vehicle suspension system as a modified example of the present invention, and states I, II, and I in FIGS.

Claims

[Scope of utility model registration request]

an orifice passage formed in the piston to communicate a piston fitted into the cylinder and first and second chambers in the cylinder partitioned by a decoy piston;
a piston rod connected to the piston and extending upward; a drive pin extending in the longitudinal direction of the piston rod within the piston rod and slidable relative to the piston rod; In a vehicle suspension incorporating a damping force switching type shock absorber comprising a control valve body attached to the lower end and capable of changing the effective flow area of the orifice passage, a damping force switching type shock absorber is installed at the upper part of the shock absorber coaxially with the piston rod. A main air spring chamber is provided, and a sub air spring chamber is provided coaxially with the piston rod directly above the main air spring chamber, and communication between the main air spring chamber and the sub air spring chamber is provided. An on-off valve having a passage bored through the piston rod and the drive pin is provided for shutoff, and the drive pin is connected to the control valve body and the on-off valve so that the control valve body and the on-off valve can be switched to a plurality of open/close modes in conjunction with each other. A suspension system for a vehicle, comprising a drive mechanism that selectively slides the suspension to a plurality of control positions.
