City rail train anti-rolling device, city rail train bogie and city rail train

Abstract

The invention discloses a city rail train anti-rolling device, a city rail train bogie and a city rail train. The city rail train anti-rolling device comprises a first pull-pressing rod, a second pull-pressing rod, a first torsion arm, a second torsion arm, a first installation base, a second installation base and a torsion rod; one end of the first pull-pressing rod is hinged to one end of the first torsion arm, and the other end of the first torsion arm is hinged to the first installation base; one end of the second pull-pressing rod is hinged to one end of the second torsion arm, and the other end of the second torsion arm is hinged to the second installation base; the torsion rod is fixedly connected between the first installation base and the second installation base; a first extending part is arranged at the end, away from the first installation base, of the first torsion arm; and a second extending part is arranged at the end, away from the second installation base, of the second torsion arm. According to the city rail train anti-rolling device, the city rail train bogie and the city rail train, the structure is simple, an independent lifting limiting protective device does not need to be additionally arranged, anti-rolling and lifting limiting protection functions can be provided at the same time, the requirements for light weight and compact design are met, the overall weight of the city rail train is decreased, and the manufacturing cost of the city rail train is reduced.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to an anti-rolling device for an urban rail train, a bogie for an urban rail train and the urban rail train. Background technique [0002] In order to maintain the stability and safety of vehicles passing through curves, more and more subway and EMU vehicles are designed with anti-rolling devices to bear the rolling force of the vehicles. Anti-rolling devices have basically become One of the necessary components for subway and EMU bogies. [0003] Common anti-roll devices see figure 1 As shown, it includes a first tension and compression rod 1, a second tension and compression rod 2, a first torsion arm 3, a second torsion arm 4, a first mount 5, a second mount 6 and a torsion bar 7, wherein the first pull One end of the compression rod 1 is hinged with one end of the first torsion arm 3, and the other end of the first torsion arm 3 is hinged with the first mount ...

AI Technical Summary

Problems solved by technology

Therefore, the existing bogie structure determines that it is necessary to use a traction device with many installation interfaces, large size, and heavy weight, so the cost is high, and the overall weight and manufacturing cost of the train are increased.
