Detailed description of the invention
See Fig. 1-5, show the first embodiment of a kind of tram absorbing noise elimination structure of the present invention, be applied in the groove-shape rail being arranged on concrete tram, the top of described groove-shape rail has the groove embedding traveling for wheel, bottom is tabular so that install and support fixing, stage casing is strip to connect and succession pressure, the both sides in stage casing with between top and bottom for arc transition is connected.
This tram absorbing noise elimination structure is provided with the first rubber element 1, second rubber element 2 and flange of rail cover 3, first rubber element 1 and the second rubber element 2 lay respectively at the both sides of groove-shape rail, flange of rail cover 3 is coated on the bottom of groove-shape rail, the both sides of described flange of rail cover 3 are provided with the barb 31 extended internally from the bottom of groove-shape rail, flange of rail cover 3 to be fixed on the bottom of groove-shape rail, and described first rubber element 1 and the second rubber element 2 are connected to the barb 31 of both sides.
In a first embodiment, described first rubber element 1 and the second rubber element 2 are the block structure be made up of microcellular rubber material, the platy structure that described flange of rail cover 3 is made for rubber; The inner side envelope of described first rubber element 1 is in the stage casing of groove-shape rail side, and the two ends inside it are formed and connect corresponding arc with described arc transition, and the middle part of inner side is provided with the recess of energy absorbing noise reduction; The inner side envelope of described second rubber element 2 is in the stage casing of groove-shape rail opposite side, two ends inside it are formed and connect corresponding arc with described arc transition, the middle part of inner side is provided with can the recess of absorbing noise reduction, described first rubber element 1, second rubber element 2 and flange of rail cover 3 by glue tight bond in groove-shape rail.
