PURPOSE: To greatly improve the riding comfortableness in a vehicle as well as to concurrently lessen dispersion stiffness control between vehicles, by increasing and/or decreasing the quantity of fluid coming in/out of plural fluid chambers in response to braking fluid pressure of the vehicle, and thereby controlling the stiffness of each suspension device in response to the deceleration of the vehicle.
CONSTITUTION: When the brake is applied, a master cylinder 42 is driven by means of both of the footing of a brake pedal 41 and the boosting action of a vacuum servo 51, and fluid pressure is applied to brake pipe lines 31F and 31R from the master cylinder 42. In this case, pressure within fluid chambers 24A and 24B communicated with the brake pipe lines 31F and 31R is increased in response to braking fluid pressure, an increase in the stiffness of a cylindrical bush allows the stiffness of each suspension device to be increased by braking fluid pressure, in short, in response to the deceleration of the vehicle. Even if axial force owing to braking reaction from the road surface is applied to a radius rod 11, the quantity of fluid coming in/out of the fluid chambers 24A and 24B is decreased, an elastic body 23 is less deformable the higher is deceleration, so that wheels are thereby firmly supported.
