Vehicle adapted to move along a rail

A vehicle adapted to move along a rail and comprising a body and a device for levitating the body on the rail, wherein the body bears in operation on the levitation device in a main bearing direction and the levitation device comprises:

• a first levitation module and a second levitation module disposed longitudinally in line under the body, each module having lateral guidance along the rail and being capable of moving relative to the body in a bearing plane perpendicular to the main bearing direction to allow each module to turn relative to the body in the bearing plane, in particular when the vehicle is moving along a curved section of the rail;
• and
• a synchronization device for synchronizing movement of the first and second levitation modules relative to the body in the bearing plane;
• wherein the synchronization device includes:
• a first hydraulic ram between the first module and the body;
• a second hydraulic ram between the second module and the body;
• and
• a fluid-flow circuit connecting the first and second rams to synchronize the actions of the rams;
• the first and second rams comprising movable rods, the first and second rams being disposed so that the rods move laterally relative to the body;
• and
• the first and second rams being connected so that lateral movement in one direction of the rod of one of the first and second rams causes lateral movement in the opposite direction of the rod of the other of the first and second rams.
