Abstract

The invention relates to a mounting structure for an anti-side-rolling torsion bar base of a railway vehicle, belonging to the field of interior design of vehicle body. The mounting structure comprises a first web plate, a second web plate and an anti-side-rolling torsion bar mounting block, wherein the upper part of the first web plate is provided with a slot with an opening upward, the first web plate is inserted and connected with a sleeper beam inner diaphragm by virtue of the slot, the top of the first web plate is fixedly connected with a sleeper beam upper cover plate, and the middle part of the first web plate is fixedly connected with a sleeper beam lower cover plate; the top of the second web plate and the sleeper beam lower cover plate are fixed; and the anti-side-rolling torsion bar mounting block is fixed at the lower parts of the first web plate and the second web plate and is provided with two mounting holes used for mounting an anti-side-rolling torsion bar. According to the mounting structure, the stress condition of the mounting structure can be improved, and welding line fatigue is avoided.

Description

technical field [0001] The invention relates to a rail vehicle anti-rolling torsion bar seat installation structure, which belongs to the technical field of car interior design. Background technique [0002] The anti-roll torsion bar of the bolster is widely used in subways and high-speed rail vehicles. The structural installation design of this important stress-bearing component requires high structural strength, especially fatigue resistance. The structure of the anti-roll torsion bar mounting seat Special consideration should be given to checking the force of the weld, and the structural design should try to avoid the occurrence of weld fatigue. Therefore, there are also types such as the use of structural fasteners to connect, and the impact characteristics of the fasteners themselves are not very high. In the previous design, the cast seat was mainly assembled and welded to the lower cover of the bolster, and the weld seam bears the additional load force generated by b...
