Elastic assembly of side bearing and manufacturing method of elastic assembly

Abstract

The invention discloses a side bearing elastic component, which comprises at least one multi-layer S-shaped metal plate, the corner of the metal plate transitions through a circular arc, and the circular arc encloses a hollow slot, and the hollow Rollers are installed in the groove. The invention is simple and convenient to assemble and disassemble, easy to maintain in the later period, has strong bearing capacity of the elastic component of the side bearing, wide adjustment range of stiffness, uniform stress, small permanent deformation, expands the scope of application of the side bearing, improves the life and stability of the side bearing, and is effective The phenomenon of stress concentration is reduced, a stable friction resistance distance is provided, and the safety of vehicle operation is improved.

Description

technical field [0001] The invention relates to a side bearing of a railway transport vehicle, in particular to an elastic component of a side bearing and a preparation method thereof. Background technique [0002] The main function of the side bearing is to slow down the snaking motion of the vehicle and ensure the appropriate turning resistance moment between the bogie and the car body. The side bearing is one of the key components to ensure the stability and safety of the railway vehicle. At present, the existing side bearings in my country include gap type elastic side bearings and constant contact elastic side bearings. Gap-type elastic side bearings, that is, when the vehicle is running in a straight line, usually the upper and lower side bearings do not touch, but there is a certain gap. Therefore, the disadvantage of the gap side bearing is that when a small side roll occurs, the vehicle body cannot be restrained by the frictional resistance moment, the critical spe...
