Elastic anti-side-rolling device of railway wagon

Abstract

The invention discloses an elastic anti-side-rolling device of a railway wagon. The elastic anti-side-rolling device of the railway wagon comprises a side rolling controller assembly, a support and atransverse limiting device assembly, wherein the side rolling controller assembly is mounted on the upper end of the support, the transverse limiting device assembly is mounted on one side of the support, a side rolling controller comprises an abrasion plate, a supporting cylinder and a first elastomer, the supporting cylinder is connected with the upper end of the support, the first elastomer isarranged in the supporting cylinder, the first elastomer is connected with the abrasion plate, the transverse limiting device assembly comprises a connecting plate and a second elastomer, the connecting plate is connected with the support, and the second elastomer is arranged on the side, away from the support, of the connecting plate. By means of the elastic anti-side-rolling device, the problemsof large side bearing rigidity, multiple abrasion and no lateral positioning of an existing wagon are solved, meanwhile, the problems that an anti-side-rolling shock absorber mechanism of a passengertrain is complex, the rigidity is not matched and the stop function is not provided are solved, and the anti-side-rolling stability requirements of a bogie of a fast wagon with the speed of 160 km / hare met.

Description

technical field [0001] The invention relates to the technical field of railway freight cars, in particular to an elastic anti-rolling device for railway freight cars. Background technique [0002] The anti-rolling device is a key component of a railway vehicle. It can buffer the rolling motion of the car body, limit the maximum swing angle, and limit the lateral displacement while adapting to the rotational displacement between the car body and the bogie. Plays an important role with uneven lines. my country's railway vehicles are divided into two modes: low-speed, heavy axle load freight and high-speed, small axle load passenger transport, with different anti-rolling mechanisms. The railway freight car adopts the side bearing anti-roll mechanism. The side bearing is mainly used as a slewing stabilization device to provide the slewing resistance moment, and the roll angle is limited by a separately set rigid stopper; the railway passenger car mainly uses the anti-roll torsi...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at the above-mentioned deficiencies in the prior art, and provides an elastic anti-rolling device for railway freight cars, which solves the problems of the existing freight car side bearings with high rigidity, high wear, and no lateral positioning, and at the same time solves the problem of reducing the anti-rolling of passenger cars. The vibrator mechanism is complicated, the stiffness does not match, and there is no stop function
