Claims

[Scope of utility model registration request]

a piston fitted in a cylinder; and an orifice passage formed in the piston to communicate between a first chamber and a second chamber in the cylinder partitioned by the 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; A damping force switching type shock absorber is incorporated, which includes a control valve body that is attached to the lower end of the orifice passage and can change the effective flow area of the orifice passage, and a first actuator that drives the control valve body via the drive pin. In the vehicle suspension, a main air spring chamber is disposed coaxially with the piston rod above the shock absorber, and a sub air spring chamber is provided coaxially with the piston rod directly above the main air spring chamber. , a compressed air generator that supplies air at a required pressure to the above-mentioned main air spring chamber and the auxiliary air spring chamber, and a spring constant that communicates and disconnects the above-mentioned main air spring chamber and the auxiliary air spring chamber. It is equipped with a switching on-off valve and a second actuator that drives the spring constant switching on-off valve, and the second actuator is configured as an air cylinder that receives compressed air at a required pressure supplied from a compressed air generator. A vehicle suspension device characterized by:
