A suspension device for vehicles between a spring-mounted passenger car and a chassis with at least one flexible spring and a damping element connected in parallel to the spring. The damping element is an active damping element with a controllable damping ratio, which features an hydraulic piston, a first bypass with constant throttle action and a second bypass with a throttle valve, whereby the throttle valve is connected to a controlling device, which opens or closes the throttle valve, as a function of the excursion rate of the flexible spring or of the lateral acceleration values of the passenger car and of the chassis.
