1. Fixing device for railway rails, comprising a ribbed plate for supporting a rail and which is adapted to be fixed on a rail substructure, the ribbed plate having ribs between which the rail is accommodated with a rail base thereof, wherein the ribbed plate is a drawn sheet member, the ribbed plate being shaped as a deep-drawn, downwardly open shell and the shell-shaped ribbed plate, including the ribs, being filled with a lower lining of a vibration absorbing material.2. Fixing device according to claim 1, wherein the lining is molded to the ribbed plate.3. Fixing device according to claim 1, wherein the ribbed plate is supported on a vibration absorbing intermediate layer which is formed in one piece with the lining.4. Fixing device according to claim 1, further comprising a vibration absorbing inlay molded to the ribbed plate on a top side thereof between the ribs.5. Fixing device according to claim 1, wherein the ribs are formed as truncated pyramid-shaped protuberances pressed-out upwardly out of the ribbed plate.6. Fixing device according to claim 1, further comprising anchoring sites for a clamping arrangement for clamping the rail base on the ribbed plate, the anchoring sites being formed by one of drawing and punching the sheet member forming the ribbed plate.7. Fixing device according to claim 6, wherein the anchoring sites are formed in the ribs.8. Fixing device according to claim 1, further comprising bearing bushes for accommodating eccentrics for a lateral adjustment of the rib plate, the bearing bushes being formed by drawing the sheet member forming the ribbed plate.9. Fixing device according to claim 1, wherein the ribbed plate has a clamping arrangement for holding clamping springs, said clamping springs being held in said clamping arrangement such that the clamping springs are tiltable into a position gripping over the rail base.10. Fixing device according to claim 9, wherein the clamping arrangement is formed by holding springs pressed out of the sheet member of the ribbed plate.11. Fixing device according to claim 9, wherein the clamping arrangement is formed by elastic tongues which are formed in one piece with the lining of vibration absorbing material that fills the ribbed plate, and the elastic tongues project upwardly through openings in the ribbed plate.12. Fixing device according to claim 1, wherein the vibration absorbing material is a synthetic resin.13. Fixing device according to claim 1, wherein the ribs form hollow spaces below the ribbed plate and the lower lining of vibration absorbing material fills the hollow spaces below the ribs.14. Fixing device according to claim 13, wherein the lower lining of vibration absorbing material has a greater thickness at positions corresponding to the ribs of the ribbed plate.15. Fixing device according to claim 1, wherein the lower lining of vibration absorbing material has a greater thickness at positions corresponding to the ribs of the ribbed plate.
