Problems solved by technology

[0003] During the operation of the vehicle, the pantograph will be subjected to greater air resistance, which will generate aerodynamic noise, which will have a greater impact on the noise inside the vehicle and the noise of the source field; at the same time, the protruding pantograph will have a greater impact on the aerodynamic resistance of the vehicle

Embodiment Construction

[0023] The core of the present invention is to provide a pantograph mounting seat for a rail vehicle, which can realize the sunken installation of the pantograph, thereby reducing air resistance and aerodynamic noise, and improving the aerodynamic performance of the train.

[0024] The present invention provides a pantograph mounting seat for a rail vehicle, which is arranged on the roof 1 of the rail vehicle, and specifically can be integrated on the roof 1 .

[0025] Such as Figure 1-3 As shown, there is a pantograph mounting seat (hereinafter referred to as the mounting seat) for installing the pantograph on the roof 1 of the rail vehicle. The basin structure is improved accordingly; the edges of the basin structure extend outwards so that the pantograph mounting seat is connected with the roof 1 by its outer edges. With the above structure, the outer edge of the pantograph mounting seat is recessed downwards, thereby forming a pit in the middle, which is a basin-shaped s...

Abstract

The invention provides a pantograph installation seat of a railway vehicle. Sunken installation of a pantograph can be achieved, air resistance and aerodynamic noise are lowered, and the aerodynamic performance of a train is improved. The pantograph installation seat is arranged on a roof of the vehicle railway, the pantograph installation seat is of a basin-shaped structure matched with the pantograph, the basin-shaped structure comprises a bottom and a side portion surrounding the bottom, and the top side of the side portion is used for being connected with the roof. The bottom is formed by sequentially connecting multiple hollow sectional materials in a lap joint mode and / or the side portion is made of the hollow sectional materials. The pantograph installation seat is of the inwards-recessed basin-shaped structure, and the whole pantograph installation seat is equivalently arranged in the roof. When the pantograph is installed, the pantograph can be wholly folded and then embedded into the roof, sunken installation of the pantograph is achieved, streamline smoothness of the roof is improved, air resistance and aerodynamic noise can be lowered, and the aerodynamic performance of the train is effectively improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a pantograph mounting seat of a rail vehicle. Background technique [0002] The pantograph, also known as the pantograph, is the electrical equipment used by the electric locomotive to receive electric energy from the catenary, and is installed on the pantograph mounting base. In the prior art, current collecting equipment such as a pantograph is usually directly installed on the arc surface of the pantograph mounting base. [0003] During the operation of the vehicle, the pantograph will be subjected to greater air resistance, which will generate aerodynamic noise, which will have a greater impact on the noise inside the vehicle and the noise of the source field; at the same time, the protruding pantograph will have a greater impact on the aerodynamic resistance of the vehicle . [0004] Therefore, how to design a pantograph mounting seat for a rail vehicle so as to real...
