<p>#CMT# #/CMT# The device has fixation parts (3, 4) fixed on a crosspiece (5). Two shields are provided on both sides of a rail (1) supporting a wheel of a wagon (2). The shields are made of rubber charged with carbon. The shields are fixed on the crosspiece and have a thickness of 30 to 50 mm and a height of 250 mm. The shields are bonded on supports (7). The supports and the shields are fixed on an angle (8) which is fixed on the crosspiece, where the angle is made of stainless steel. Each support has a thickness of 40 mm and a height of 250 mm. The shields have a length from 6 to 10 m. #CMT#USE : #/CMT# Used for reducing sound emission of a metallic wheel that rolls on a metallic rail (claimed) such as railway track in a railway station, at the proximity of a residence, on a bridge or when carrier surface of the rail is disposed on an embankment preventing placement of a shield. #CMT#ADVANTAGE : #/CMT# The rubber shields are fixed on both sides of the rail and fixed on the crosspiece, thus permitting to absorb the sound upon its emission from a sound source and permitting to avoid the propagation of the sound in the environment. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a metallic wheel`s sound emission reduction device. 1 : Rail 2 : Wagon 3, 4 : Fixation parts 5 : Crosspiece 7 : Supports 8 : Angle #CMT#POLYMERS : #/CMT# The shields are made of rubber that is charged with carbon.</p> |
