Arrangement for tilting a railbound vehicle in track curves

Arrangement on a railbound vehicle comprising a car body, at least first and second bogies and at least one hydraulic cylinder mounted at each side of each bogie, each said cylinder including a lower working space and an upper working space and each said cylinder being attached at its lower end to the bogie side and at its upper end to the car body for tilting the car body in track curves, and includes

• first interconnection means for communicating the lower working spaces of left-handed cylinders of the respective first and second bogies and second interconnection means for communicating said lower working spaces of said left-hand cylinders with the upper working spaces of right-hand cylinders of the respective first and second bogies, said first and second interconnection means forming a first freely communicating conduit system,
• third interconnection means for communicating the lower working spaces of said right-hand cylinders of the respective first and second bogies and fourth interconnection means for communicating said lower working spaces of said right-hand cylinders with the upper working spaces of said left-hand cylinders of the respective first and second bogies, said third and fourth interconnection means forming a second communicating conduit system, and
• a single servo valve connected to said first and second communicating conduit systems to control the tilt of the car body by forcing all of said hydraulic cylinders of the vehicle to cooperate in order to tilt the car body through a coordinated rotational movement.
