[0003] The side frame of the railway freight car bogie in my country is directly installed on the bearing saddle. In order to take into account the straight and curved running performance of the bogie, there is a gap between the side frame and the bearing saddle in the horizontal and vertical directions. Relative displacement and mutual friction will cause wear on the side frame and bearing saddle, shorten the service life of the side frame, and greatly reduce the economic benefits of the bogie

Embodiment Construction
[0009] As shown in the figure, the present invention includes a side frame 1, a bearing saddle 3, and a pedestal wear plate 2. The pedestal wear plate 2 is an opening structure, and the top size of the opening structure is larger than the width of the side frame 1, and the size of the middle part of the opening structure is slightly smaller than The width of the side frame 1 ; the side frame 1 is installed on the pedestal wear plate 2 , and the pedestal wear plate 2 is installed on the bearing saddle 3 .
[0010] Press the pedestal wear plate 2 into the side frame 1, make the pedestal wear plate 2 contact with the side frame 1, rely on the contraction force generated by the opening of the pedestal wear plate 2 to clamp the side frame 1, make the side frame 1 and the pedestal wear plate 2 are assembled into one body, and finally installed on the top surface of the bearing saddle 3 together.
[0011] When the vehicle is running, there is no relative displacement between the side...

The invention relates to a snap-in side frame guide frame wearing plate device of a steering bogie, which comprises a side frame and a carrying saddle, wherein the side frame is directly arranged on the carrying saddle. The snap-in side frame guide frame wearing plate device is characterized by also comprising a guide frame wearing plate, wherein the guide frame wearing plate has an open structure; the size of the top part of the open structure is bigger than the width of the side frame; the size of the middle part of the open structure is slightly smaller than the width of the side frame; the side frame is arranged on the guide frame wearing plate; and the guide frame wearing plate is arranged on the top surface of the carrying saddle. With the structure, the snap-in side frame guide frame wearing plate device has the advantage of prolonging the service life of the side frame.
Description
technical field [0001] The invention relates to a mounting device, in particular to a pedestal wear plate device for a bogie side frame. Background technique [0002] Railway freight car bogies generally adopt a connection structure in which the side frame is directly installed on the bearing saddle. This structure has the function of transmitting load and providing wheel set positioning. [0003] The side frame of the railway freight car bogie in my country is directly installed on the bearing saddle. In order to take into account the straight line and curve running performance of the bogie, there is a gap between the side frame and the bearing saddle in the horizontal and vertical directions. Relative displacement and mutual friction will cause wear on the side frame and bearing saddle, shorten the service life of the side frame, and greatly reduce the economic benefits of the bogie. Contents of the invention [0004] The technical problem to be solved by the present inv...
