Definitions
- the present invention relates to a device for supporting and wedging a railway rail on a sleeper.
- Devices of this type include in particular an elastic sole on which the base of the rail rests and insulating stops inserted between the rail and the elastic fasteners which are fixed on inserts anchored laterally in the cross-member.
- the sole is generally of uniform thickness while the stops are in abutment on the shoe of the rail without their lower edge coming into contact with the sole.
- the shape and position of the stops do not allow good compression resistance to be obtained under the action of the lateral forces generated by the rolling stock and transmitted by the rail.
- the object of the present invention is to solve these problems satisfactorily.
- the clearance between the lower edge of the stops and the lateral parts of the sole is between 0.5 mm and 5 mm.
- the difference in thickness between the central part and the lateral parts of the sole is greater than or equal to 3 mm when the rail is in place and according to an alternative embodiment, the thickness of the lateral parts of the sole is less than or equal to half the thickness of the central part.
- the position of the lower edge of the stop is located at least 2 mm below the level of the base of the rail and preferably consists of a substantially horizontal plane face. According to other characteristics, the lateral parts are engaged, for the setting of the sole, in corresponding shoulders formed on the upper face of the cross-member.
- the length of said lateral parts is less than the length of the central part.
- said lateral parts of the sole are full while the central part has recessed areas.
- the device of the invention makes it possible to easily remove the sole from its location under the rail section by raising the lateral parts to 90 "and by exerting a traction force parallel to said section.
- FIG. 1 shows a cross-sectional view of the device of the invention associated with the rail fastening system
- FIG. 1 is intended for supporting and wedging a rail R of a railway on a sleeper T.
- This device comprises an elastic sole 1 on which the base Ra of the rail R rests and two symmetrical insulating stops 2,2 ′.
- the stops 2.2 ′ are interposed between the rail R and the elastic fasteners A, A ′ which are fixed on inserts 1.1 ′ anchored laterally in the cross member T.
- the sole 1 is in one piece comprising a central part 10 which supports the base Ra of the rail R and two symmetrical lateral parts 11,11 'of smaller thickness, arranged under the lower edge 20,20' of the stops 2.2 '. which is itself located below the level of the underside of the base Ra of the rail R.
- the stops 2.2 ' have an upper part 2a, 2a' which is arranged under one of the branches of the fastener A, A 'bearing against the shoe of the rail R and which extends downwards and a lower part 2b, 2b 'substantially vertical ending with the lower edge 20,20'.
- the internal faces of the stops 2,2 ' match the external profile of the base of the lower part 2b, 2b' of the rail R both at the level of the upper part 2a, 2a 'and of the lower part 2b, 2b'.
- the lower edge 20, 20 ′ is produced in the form of a substantially horizontal plane face.
- the rail R placed on the central part 10 of the sole 1 slightly compresses the latter by its own weight and by the tightening force of the elastic fasteners, but in this rest position there is a clearance between the lower edge 20 , 20 'of the stops 2.2' and the upper face of the lateral parts 11.11 'of the sole 1.
- the clearance between the lower edge 20,20 'of the stops 2,2' and the upper face of the lateral parts 11,11 ' is preferably between
- the lower edge 20, 20 ′ of the stops 2.2 ′ is located at least 2 mm below the level of the base Ra of the rail R resting on the central part 10.
- the central part 10 of the sole 1 has recessed areas 10a in the form of grooves or cells so as to have a determined degree of compressibility.
- the lateral parts 11, 11 ' are full because they serve as stop surfaces for the lower edge 20, 20' of the stops 2.2 'and must therefore be harder than the central part 10.
- FIG. 2 is a partial perspective view of a particular embodiment of the sole 1.
- the length of the lateral parts 11, 11 ′ of the sole 1 is less than the length of the central part 10.
- the side parts 11, 11 ′ are engaged in shoulders Ta formed on the upper face of the cross-member T for wedging said sole.
- the outer edge of the lateral parts ll'll ' comprises a cutout lla, lla' intended to release the orifices Tb from the crosspiece T which are intended to receive the anchoring members of the inserts 1,1 '.
