Abstract

The invention relates to a swing device for a swing bogie of a rail wagon, which comprises a guide frame shaking seat, a bearing saddle and a side frame, and is characterized in that: the guide frame shaking seat is elastic and consists of an elastic guide frame shaking seat main body and two sections of longitudinal positioning baffle plates which are integrally connected with the lower part of the main body; the bottom surface of the elastic guide frame shaking seat main body and the top surface of the bearing saddle are planes and form planar positioning contact; and the two sections of longitudinal positioning baffle plates on the lower part of the elastic guide frame shaking seat main body form planar positioning contact with the bottom surface and the side surface of a guide frame of the bearing saddle respectively. The problem that the swing device for the swing bogie cannot be timely reset to cause eccentric wear is solved; and the swing device has high economic value and social value.

Description

technical field [0001] The invention relates to a swing device for a swing bogie of a railway freight car, which belongs to a component of a railway freight car. Background technique [0002] The oscillating device of the oscillating bogie includes a pedestal oscillating seat, a bearing saddle, a side frame, etc. as attached figure 1 As shown, the rocking seat of the pedestal frame is made of alloy steel metal material, and the lower part is a convex arc surface, which corresponds to the hardened concave arc surface on the top of the bearing saddle. The upper swing point of the swing bogie swing device is installed on the left and right It is realized by rolling between the convex arc surface of the pedestal rocking seat on the top of the side frame and the concave arc surface on the top of the bearing saddle. The rolling friction force between the concave arc surfaces realizes the swing function. However, since the center lines of the convex arc surface and the concave ...
