Bogie of urban automatic passenger transport system vehicle

Abstract

The invention relates to a bogie of an urban automatic passenger transport system vehicle. The bogie comprises a guide frame serving as a main body support of the bogie, and an axle, and the lower part of the axle is connected with the upper part of the guide frame through a pivotal bearing for connecting an upper vehicle body; the bogie further comprises a pair of traveling wheels which is arranged on the two sides of the axle, travels on a track beam and is used for bearing the overall weight of the bogie, and guide wheels which are mounted on the front side and the rear side of the guide frame and used for guiding the bogie. Compared with the prior art, the bogie provided by the invention has the advantages that a non-linear hydro-pneumatic spring is used as a transverse shock absorber to buffer transverse vibration, the rigidity and damping are variable, and the dynamic performance can be changed through oil filling and air filling so as to adapt to different line conditions; and two pairs of longitudinal pull rods are used for transmitting longitudinal force, so that the traction effect is achieved, and the anti-nodding effect is also achieved.

Description

technical field [0001] The invention relates to the technical field of urban automatic passenger transport system vehicles, in particular to a bogie for urban automatic passenger transport system vehicles. Background technique [0002] The urban automatic passenger transportation system refers to the passenger transportation system that runs on rails or track beams, adopts multiple groups, and realizes unmanned driving. The urban automatic passenger transportation system vehicle is a relatively new vehicle system at present, and has many advantages. Rapid development, used by many large airports in the world. The urban automatic passenger transportation system is also called the APM system. Its central control unit can automatically control the operation of the vehicle, without the need for professionals to operate the vehicle, and can fully realize automatic driving. [0003] Vehicles of urban automatic passenger transportation systems are often carried by rubber tires, co...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is exactly to provide a kind of bogie of urban automatic passenger transportation system vehicle in order to solve the above-mentioned problem, aim at the problem that the lateral stability of existing APM vehicle is not good enough, on the basis of Innovia APM 300 type vehicle bogie, propose A new type of bogie structure, which can adjust its lateral stiffness and lateral damping, effectively alleviate lateral vibration and improve lateral stability
