Embodiment Construction
[0013] The selection method of railway passenger car suspension spring, weighing the passenger car body, and measuring the load distribution P of the four supporting positions of the passenger car body A ,P B ,P C ,P D , and according to the load distribution of the four supporting positions, determine the heavy end and light end of the passenger car body, as well as the heavy side and light side of the heavy end and light end; measure the axle box spring and bolster spring According to the free height and stiffness of the springs, the axlebox springs and bolster springs are sorted in descending order of the product of the free height and stiffness of the springs; There are 8 groups, and the 8 bolster springs are divided into 4 groups; the 8 groups of axle box springs are in the order of the product of free height and stiffness (elastic force equivalent) from large to small, according to the outer side of the heavy end and the light end of the heavy end. The outside of one ...
