Abstract
The invention relates to a rail fastening on a tie having fastening screws and loop-shaped tension clamps in which the track width can be adjusted horizontally in a stepless manner using wedge elements, the rail being arranged on a ribbed plate, the ribs of which run at an angle to the rail and a wedge that can be moved in the longitudinal direction of the rail being arranged between rail foot and the ribs. The wedge is preferably guided on the support. This makes possible effective horizontal lateral displacement of the rail or modification of the track with the use of simple and inexpensive plastic parts.
Claims17
A fastening to fasten a rail to a tie or rail bed that allows for track width adjustment, the rail having a rail foot, said fastening comprising:
- a support plate (1, 100) receiving the rail in transverse orientation thereto, said support plate having a pair of juxtaposed ribs (16, 17, 116, 117) extending in parallel, one on either side of said rail foot and adjacent thereto, said support plate ribs extending at an oblique angle relative to a longitudinal direction of the rail and at an angle to said rail foot;
- a pair of wedges (24, 224) extending in opposite directions, one each between a respective rail foot and a support plate rib adjacent thereto;
- wherein the rail foot is fastened to said support plate with a spring tension clamp (2, 200) having a loop end pressing said rail foot downward and wherein each said wedge is positioned between a respective support plate rib and said rail foot having been such positioned in a stepless manner to steplessly horizontally adjust the rail foot location on the support plate.
A fastening to fasten a rail to a tie that allows for track width adjustment, the rail having a rail foot, said fastening comprising:
- a support having a rib and a wedge;
- wherein the rail is arranged on and fastened to said support using fastening screws and a loop shaped tension clamp, said rib of said support runs at an oblique angle relative to a longitudinal direction of the rail and at an angle to the rail, and said wedge can be moved in the longitudinal direction of the rail and is arranged between the rail foot and the rib;
- wherein said support has a first counter bearing for the rear loop of said loop shaped tension clamp when said loop shaped tension clamp is in a pre-assembly position and a second counter bearing for the rear loop when said loop shaped tension clamp is in a usage position, in which a loop end presses said rail foot downward.
A fastening to fasten a rail having rail feet to a tie, wherein there is provided a stepless horizontal adjustment of said rail feet position with respect to said support, said fastening comprising:
- a support plate, said support plate receiving said rail in a transverse position thereto, said support plate including bearing structures on either end thereof, said bearing structures terminating in a rib proximate to said rail, wherein said ribs extend in parallel to one another at an oblique angle relative to a longitudinal direction of the rail and at an angle to said transverse positioned rail feet;
- a pair of wedges facing in opposite directions to one another, each positioned between a respective rib and a respective rail foot to be engaged therewith, to exert a horizontal force, longitudinally of said support plate extension, against a rail foot as a said wedge is moved inwardly in a stepless manner wherein a loop end of a tension clamp is arranged to press said rail foot downward.
