Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] like figure 1 and figure 2 As shown, a pantograph deflector 1 of a rail vehicle includes two side deflectors 2 arranged longitudinally along the roof on both sides of the pantograph, and two front and rear deflectors arranged at the front and rear of the pantograph. The wind deflector 3 is arranged in a ring shape along the periphery of the roof pantograph.

[0028] like figure 1 As shown, in the first embodiment of the present invention, two side shrouds 2 and two front and rear shrouds 3 are a continuous integral structure,

[0029] like figure 2 As shown, in the second embodiment of the present invention, two side wind deflectors 2 and two front and rear wind deflectors 3 are arranged separately, and two front and rear wind deflectors 3 are arranged on the sides of the two side wind deflectors 2 middle.

Abstract

The invention relates to a pantograph guide device of a railway vehicle, which comprises an air guide sleeve fixed on the vehicle roof. The air guide sleeve consists of a lateral air guide sleeve, a front air guide sleeve and a rear air guide sleeve; the surroundings of the pantograph are annularly arranged. The lengthwise section of the lateral air guide sleeve is roughly a trapezoid with a narrow top and a wide bottom; the middle lower part of the side of the lateral air guide sleeve which is corresponding to the pantograph is provided with a chamfer angle used for widening the width of the bottom of the air guide sleeve; the lengthwise sections of the front air guide sleeve and the rear air guide sleeve are roughly triangular; the lateral air guide sleeve is a box structure, which is internally and transversely provided with a plurality of first stiffener plates and second stiffener plates; the front air guide sleeve and the rear air guide sleeve are thin-shell structure, which are internally provided with a plurality of stiffener plates. When the railway vehicle runs at high speed, the air guide sleeve can prevent the influence of air stream to the pantograph, thus reducing the noise source of the pantograph and effectively reducing noise of the pantograph. The air guide sleeve can be fixed on the vehicle roof alone, thus being free from the influence of the structural form of the pantograph, and suitable for the pantograph of any structural form.

Description

technical field [0001] The invention relates to a device capable of reducing the pantograph noise of a rail vehicle, in particular to a pantograph for a rail vehicle installed on a high-speed rail vehicle with a speed of 200 km / h or more and effectively reducing the noise of the pantograph. streaming device. Background technique [0002] The current high-speed rail vehicles with a speed of more than 200km / h are all driven by the pantograph on the roof to transmit power. When the vehicle is running at high speed, the noise generated is mainly the mechanical noise generated by the vehicle itself and The noise generated by friction with the air, the noise generated on the roof is mainly the noise generated by the friction between the pantograph and the air, and the faster the speed of the vehicle, the greater the noise it generates. [0003] According to relevant international standards and combined with the actual situation in China, the user requires that when the EMU passes...
