Claims
- 1. Device for compensating a tilt of a carriage body of a rail vehicle when travelling around bends at high speeds, comprising:
- a passive tilting system, including:
- a tilt compensator with a four-bar mechanism, and an energy store means, the tilt compensator being operationally connected to the energy store means to remove parasitic rigidities of the tilt compensator during travel of the device on bends in a superelevated track, the tendency of the carriage body to tilt outside of the bend being compensated, so that a carriage body contour of the vehicle, having an approximate shape of a parallelogram, complies to a predetermined outline profile, the four-bar mechanism including a transversely movable transverse support mounted in a floating manner and supported on a carriage body suspension for providing vertical cushioning for the carriage body, the energy store means including an air spring means displaceable laterally with respect to the carriage body to tilt the carriage body toward an inside of a bend when the carriage body travels around the bend.
- 2. Device, according to claim 1, wherein the four-bar mechanism coupled to the energy store means produces a tilt of the carriage body towards the inside of the bend, the carriage body being supported on an additional transverse suspension.
- 3. Device, according to claim 2, wherein the additional transverse suspension comprises additional transverse springs braced with a respective clamping screw and mounted above and below the floating transverse support.
- 4. Device, according to claim 2, wherein the additional transverse suspension comprises four transverse springs mounted above the floating transverse support.
- 5. Device, according to claim 1, wherein the four-bar mechanism comprises at least one wobble stabilizer, two laterally mounted, hinged supports coupled at one end, respectively, to the stabilizer and coupled at a second end, respectively, to the transverse support.
- 6. Device, according to claim 5, wherein the two hinged supports are inclined convergently upwards and are fixed to the transverse support at hinge points in such a manner that, during travel on bends, at least one of the two hinged supports located on an outside of the bend rises and imposes on the transverse support a vertical aligned rotary movement.
- 7. Device, according to claim 6, wherein the transverse support is mounted in a floating manner between the carriage body suspension and an additional transverse suspension connected to the carriage body and further characterized in that turning out of the carriage body over a bogie associated with the device, due to travel on bends, is absorbed by the additional transverse suspension.
- 8. Device, according to claim 7, further comprising a resilient transverse stop comprising two transverse buffers with stop faces provided between the carriage body and the floating transverse support.
- 9. Device, according to claim 1, wherein the transverse support is mounted in a floating manner between a carriage body suspension and an additional transverse suspension connected to the carriage body, and further characterized in that turning out of the carriage body over a bogie, associated with the device, due to travel on bends, is absorbed by the additional transverse suspension.
- 10. Device, according to claim 9, wherein the additional transverse suspension comprises additional transverse springs braced with a respective clamping screw and mounted above and below a floating transverse support.
- 11. Device, according to claim 1, wherein the spring means comprises two horizontally mounted transverse air springs, the air springs being mounted opposite one another in pairs between two auxiliary longitudinal supports of a bogie frame associated with the device, and a pivot connected to the transverse support and projecting down from the transverse support and engaging the air springs.
- 12. Device, according the claim 11, wherein the two transverse air springs are connected together in an intercommunicating manner via a choke diaphragm.
- 13. Device, according to claim 11, wherein each air spring comprises an outer guide fixed to the pivot, a cone fixed to one of the two auxiliary longitudinal supports of the bogie frame and a rolling bellow which is fixed between the outer guide and the cone.
- 14. Device for compensating for tilt of a carriage body of a rail vehicle during travel on bends at high speeds by means of a passive tilting system, comprising: a tilt compensator, which during travel on bends in a superelevated track, compensates for thrust of the carriage body to tilt the same towards an outside of the bend, the tilt compensator including a four-bar mechanism including a transversely movable transverse support mounted in a floating manner and supported on a carriage body suspension for providing vertical cushioning for the carriage body, and an air spring means displaceable laterally with respect to the carriage body to tilt the carriage body toward an inside of a bend when the carriage body travels around the bend.
