The 18-1750.0 bolster, side frame and bolster drawing number of our company are 1750.00.001, and the drawing number of the side frame is 1750.00.002. It is suitable for the rail distance 1520mm railway freight car bogies. The technical parameters and related information of type 18-1750.0 bolster and side frame are as follows:
A) suitable for Railway Freight Car Bogies with gauge 1520mm and wheelbase 1750mm.
B) uniaxial maximum bearing capacity of 23.5 tons;
C) the structural dimensions and installation dimensions of the side frame are the same as those of the 18-100 side frame, and only the reinforcement structure of the R55 area is improved.
D) the structure size and installation size of the bolster are also basically the same as that of the 18-100 type bolsters. Apart from the addition of R30 strengthening and filling structures on the sides of the side walls of the side bearing body, the depth of the thrust edge of the heart disc is less 3mm than that of the 18-100 type bolster, that is, the depth of the 18-100 type rocking disc thrust edge is 37+ 1-2, and the 18-1750.0 type rocking pillow disc pushes the edge. The depth is 34 + 1.
The technical parameters and relevant information of the 18-1750.0 type bolster and side frame show that the technical parameters of the other aspects are the same except that the depth of the thrust edge of the heart can not be interchanged with the 18-100 bolsters, and the 18-1750.0 side frame is completely interchangeable with the 18-100 type side frame.
