Kinetic energy converter for a pneumatic transportation system

A kinetic energy converter for pneumatic transportation system comprising:

• a kinetic energy converter installed in a bogie of a pneumatic propulsion vehicle having a bogie structure formed by a bolster and side frames and at least two axle sets, each axle set having two metallic wheels which roll on rails fastened onto a vehicle guideway, said kinetic energy converter further comprising:
• an electric generator provided with a housing within which a rotor is adapted to spin, said rotor provided with a rotor pulley which is moved by a belt and driven by a freewheel pulley mounted on a drive shaft provided with shaft ends wherein wheel hubs of the bogie structure are mounted;
• wherein the axle set comprises guide tubes having external and internal ends, said external ends connected to the side frames of the bogie structure and said internal ends having flanges which are connected with supports of the electric generator housing;
• and
• wherein the axle set is provided with side clutches which actuate on splines and on the freewheel pulley, interrupting or transmitting torque to the belt of the electric generator rotor;
• and
• wherein the side clutches are laterally displaced by an electrical, hydraulic or pneumatic actuator which are adapted to uncouple the kinetic energy converter.
