Abstract (en)
[origin: EP0625456A1] The device contains at least one fan (20) which is arranged in the vehicle body (1) of the rail traction unit and is connected to an air duct (17, 18) which is assigned to the traction motor (8) and/or to a cooling system (12) for assemblies (13). The air duct (17, 18) is provided over at least part of its length, e.g. in a suction-side section (17a, 18a, 43, 44) with panelling (38, 38a, 38b) which consists of a mat made of a sound-absorbing material. By means of the panelling (38, 38a, 38b) it is possible to achieve effective reduction in particular of the noise of the air of the fan (20) which is emitted in the direction of flow and counter to the direction of flow of the cooled air, and of the noise of flow within the air duct (17, 18). The device is mainly provided for use on railway traction units with high driving powers. <IMAGE>
