Suspension system for levitation vehicles

Passive-levitation vehicle for moving over a path, comprising:

• a passenger compartment,
• a levitation skid slidable on the path and capable of developing a levitation force to support the compartment at a certain distance from the path,
• a suspension, connected between the compartment and the skid, comprising:
• an articulated kinematic structure configured to confer degrees of freedom and relative constraints between the skid and the compartment;
• a passive elastic element connected between the skid and the compartment;
• a controlled-dynamic element comprising an electric actuator situated between the skid and the compartment and able to exert a force having controlled dynamics between the skid and the compartment;
• the passive elastic element and the controlled-dynamic element being mounted in parallel to each other and connected at their ends, respectively to the skid and the compartment;
• at least one sensor including a sensor for detecting the distance between the skid and the path,
• an electronic circuit, connected to the sensor and to the controlled-dynamics element, for carrying out a feedback control in order to adjust said distance between the skid and the path, the electronic circuit being able to
• read a signal emitted by the sensor, and
• as a function of the signal, drive the controlled-dynamic element to impose a desired course to the distance.
