Magnetic levitation vehicle current collector

Abstract

The invention discloses a magnetic levitation vehicle current collector. The current collector includes a base, a lifting bow assembly arranged on the base and a bow head assembly arranged on the lifting bow assembly; the bow head assembly includes a bow head support connected with the lifting bow assembly, a buffering cylinder body arranged on the bow head support, a guiding rod matched with thebuffering cylinder body in a sliding mode and a sliding board fixed to the guiding rod and used for being in electrical contact with a contact rail; additionally, a pressure adjusting valve used for controlling the pressure value of the buffering cylinder body to be maintained at a preset pressure value is arranged between the buffering cylinder body and a corresponding pressure source. Accordingto the structure of the current collector above, by arranging the pressure adjusting valve between the buffering cylinder body and the corresponding pressure source, when the sliding board is in contact with the contact rail, the contact strength can always remain at the preset pressure valve, and fast response to high-frequency vibration, resulted from unevenness of the contact rail, of the sliding board can be achieved, so that the current collection stability of the current collector is further improved.

Description

technical field [0001] The invention relates to the technical field of maglev vehicles, in particular to a current collector of a maglev vehicle. Background technique [0002] With the development of society, the development concept of urban rail transit such as energy saving and environmental protection has been continuously improved, and maglev vehicles have emerged as the times require. The so-called maglev vehicles refer to the use of electromagnetic force as the source of levitation force. The vehicle is suspended at a certain distance above the track and is driven by electromagnetic force. Forward running without friction between the vehicle and the track. [0003] The vehicle adopts the current collector installed on the bottom side of the vehicle to contact the contact rail to obtain current. The maglev vehicle has the advantages of environmental protection, strong climbing ability, small turning radius and low noise. It is precisely because of the above characteris...

AI Technical Summary

Problems solved by technology

Although the current collector and the contact rail can realize contact and disengagement, the contact pressure is unstable, and because the installation of the contact rail is not smooth, the sliding plate of the current collector slides along the contact rail at high speed. High-frequency vibrations are generated, which makes the stability of current receiving poor

[0005] To sum up, how to solve the problem of poor flow stability of the current collector of maglev vehicles, especially for fast maglev vehicles with a speed of 160 kilometers, has become a technical problem to be solved urgently by those skilled in the art
