Example Embodiment

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] As used herein, "several" refers to an indefinite number, usually two or more; and when "several" is used to indicate the number of certain parts, it does not necessarily mean that the number of these parts is the same.

[0033] The descriptions of "horizontal", "vertical", "upper", "lower" and so on in this article that indicate the orientation or position relationship are all based on the orientation or position relationship during the actual operation of the train; when the train is running, its driving direction It is the longitudinal direction, in the horizontal plane, the direction perpendicular to the longitudinal direction is the transverse direction, and in the vertical direction, the direction away from the groun...

Abstract

The invention discloses a maglev train and a running gear thereof, wherein the running gear comprises two suspending frames which are arranged in the driving direction at intervals and connected through a longitudinal beam. Slots which reduce the torsional rigidity of the longitudinal beam are formed in the circumferential wall of the longitudinal beam, the torsional rigidity of traditional longitudinal beams can be reduced, the coupled effect between the two suspending frames which are connected through the longitudinal beam can be relieved and then difficulty and energy consumption of suspension control are greatly reduced; the suspending frames are connected with a train body through air springs which have large displacement in lateral and vertical directions respectively, not only is flexible supporting to the train body realized, but also traditional secondary suspension structures can be substantially simplified, and the weight of the running gear is reduced; a vertical shock absorber and a lateral shock absorber with proper damping values are arranged between the suspending frames and the train body to attenuate vibration of the train body and improve stability and comfort level during the train travelling. In addition, a lateral stopper and a vertical stopper are arranged between the suspending frames and the train body and can stop the train from over lateral moving, rollover and overturn in the operational process.

Description

technical field [0001] The invention relates to the technical field of maglev trains, in particular to a maglev train and its running part. Background technique [0002] Maglev trains usually include a car body and a number of running parts located at the bottom of the car body. The running parts are mainly used to support the car body, and can transmit the levitation force, guiding force, traction force and braking force to the car body through the secondary suspension system. , to ensure that the maglev train has the ability to smoothly pass through horizontal curves, torsional curves and vertical curves. [0003] The running part usually includes two suspension frames distributed at intervals along the travel direction, and the two suspension frames are connected through longitudinal beams. In this way, when the train passes through the transitional curve, there will be a relative rolling motion between the two suspension frames of the same running part, which requires t...
