Axle box embedded bogie for high speed railway wagon

Abstract

The invention discloses an axle box embedded bogie for a high speed railway wagon. An H-shaped integral truss and an embedded axle box are adopted; an anti-snake vibration absorber and a secondary transverse vibration absorber are arranged on the truss; the anti-snake vibration absorber is longitudinally connected to the two sides of a truss side frame; and the secondary transverse vibration absorber is transversely connected to the end part of a truss small cross beam. A primary suspension of the axle box embedded bogie for the high speed railway wagon is located by using an axle box rotatingarm; and under coordination of a wheel pair crossed supporting device, the vehicle stability is enhanced. Compared with a traditional truck, the axle box embedded bogie for the high speed railway wagon has the advantage that a problem of insufficient anti-roll ability provided by a secondary suspension is solved because an anti-roll torsion bar device is additionally mounted. According to the axle box embedded bogie for the high speed railway wagon, a high speed railway wagon bogie overall scheme satisfying a cargo transporting realistic demand is designed for a problem that an operation speed of an existing truck bogie cannot satisfy a demand. According to the axle box embedded bogie for the high speed railway wagon, on the basis of an axle box embedded type integral truss structure bogie, the critical value of velocity is increased by improving the anti-snake motion performance and the motion stability during operation.

Description

technical field [0001] The invention belongs to the technical field of rail transit. Specifically, it relates to an axle box built-in bogie applied to high-speed railway freight cars. Background technique [0002] Worldwide, there are mainly two types of truck bogies available. Countries in North America, Asia, South Africa and other regions mainly use three-piece bogies, while European countries mainly use integral frame bogies. In the development of the bogie, it is found that the requirements of improving the stability of the bogie's lateral motion and the requirement of improving the curve passing performance of the bogie are often contradictory. The use of radial bogies is an effective measure to solve the contradiction between stability and ability to pass through curves. Among them, the first successful and put into use is the Scheffel sub-frame self-steering bogie of the South African Railway. The bogie uses an arched beam to connect the left and right sides of e...
