Abstract
A sound-damping rail assembly for a track for rail vehicles comprises a rail having a pair of downwardly converging flanks below its head and above its base. The rail is received in a frame with downwardly inclined sides, the flanks being braced against these sides by elastomeric layers which are interposed between the flanks and the sides. A further elastic layer can be provided between the base or foot of the rail and the inner supporting surface of the frame and such layers may completely envelop the rail except for the head.
Claims11
A sound-damping rail assembly for a track along which a vechicle can ride, said rail assembly comprising:
- a rail having
- a base,
- a web extending upward from said base,
- a head supported on said web and having an upper surface along which a vehicle wheel can ride, and
- a region below said head and above said base of downwardly tapering cross section and hacing a pair of straight-line downwardly converging flanks defining an included flank angle;
- frame enclosing bottom and side regions of said rail and formed with
- a pair of sides spacedly juxaposed with said flanks, forming an included side angle greater than the flank angle, and converging straight-line downwardly, and
- an upwardly directed support surface spacedly juxaposed with the base;
- a base elastic layer interposed and bridging the space between the support surface and the base;
- and
- respective side elastic layers interposed and bridging the spaces between each of said sides of said frame and the respective flanks.
A sound-damping rail assembly for a track along which a vehicle can ride, the rail assembly comprising:
- a rail having
- a base,
- a web extending upward from the base,
- a head supported on the web and having an upper surface along which a vehicle wheel can ride, and
- a region below the head and above the base of downwardly tapering cross section and having a pair of straight-line downwardly converging flanks defining an included flank angle;
- a frame enclosing bottom and side regions of the rail and formed with
- a pair of sides spacedly juxaposed with the flanks, forming an included side angle greater than the flank angle, and converging straight-line downwardly, and
- an upwardly directed support surface spacedly juxaposed with the base;
- a base elastic layer interposed and bridging the space between the support surface and the base, the base elastic layer defining with said frame member a cavity of a predetermined height and cross section and the base layer being of such elasticity that, only when the rail is subjected to a load in excess of a normal load corresponding to a load applied by a normally loaded vehicle, the base elastic layer is compressed to fully fill said cavity;
- and
- respective side elastic layers interposed and bridging the spaces between each of the sides of the frame and the respective flanks.
