Abstract

The invention relates to an elastic side bearing, comprising a side bearing base, wearing plates, a wearing plate installing seat, elastic joints, elastic joint installing seats, a connecting guide rod and side bearing springs, wherein a locating boss, a circular groove and a locating frustum are arranged on the side bearing base; a locating boss, a circular groove and a locating frustum are also arranged on the wearing plate installing seat; concave holes are arranged on the other side of the wearing plate installing seat at intervals and the wearing plates are pressed in the concave holes; one elastic joint installing seat is arranged on the side bearing base and the other elastic joint installing seat is arranged on the wearing plate installing seat; the elastic joints are arranged in the elastic joint installing seats; the side bearing base and the wearing plate installing seat which are respectively provided with the elastic joints are arranged oppositely; the side bearing springs are respectively sleeved on the two locating frustums; and the connecting guide rod is fixed in through holes of the elastic joints. According to the elastic side bearing provided by the invention, the problems of creep deformation and axial clearance of the elastic side bearing can be solved, therefore, the operation security of vehicles is guaranteed; and the elastic side bearing can be widely applied between the bogie swing bolster and the car body of a rail wagon.

Description

technical field [0001] The invention relates to an elastic side bearing, in particular to an elastic side bearing used between a bogie bolster and a car body of a railway freight car. Background technique [0002] At present, elastic side bearings made of rubber plus springs or rubber are used between the bogie bolster and the car body of railway freight cars. The use of the elastic side bearings ensures the stability and safety of the railway freight cars. However, in practical applications, on the one hand, due to the rubber and spring composite structure or rubber structure of the elastic side bearing, after a period of application, the elastic side bearing will creep and cause permanent deformation, resulting in The following problems will occur in the metropolis: 1. After the permanent deformation of the elastic side bearing, its stiffness generally increases, and the stiffness of the elastic side bearing will further increase after the backing plate is added, but becau...
