Description

Technical Field

[0086]

[0087] It can be seen from Table 1 above that when the web thickness H1 is between 36 and 48 mm, the corresponding guiding force is greater than the guiding force corresponding to other web thicknesses. In Example 1, H1 is preferably 36 mm, which can reduce manufacturing costs (the suspension force is above 28 kN to meet the load standard. The guiding force is generated when the centerline of the train deviates from the center of the track. The greater the maximum guiding force, the greater the deflection displacement and the stronger the reset ability).

[0088] Table 2 Comparison of different plate thicknesses

[0089]

[0090] As can be seen from Table 2, the guiding force of the plate thickness H2 in the range of 26-28 mm is greater than the guiding force of the plate thicknesses of other types. In Example 1, H2 is preferably 26 mm, which can effectively reduce the manufacturing cost.

[0093] It can be seen from Table 3 that the guiding force when the angle θ is 83°-89° is greater than the guiding force at other angles. When the angle θ is 83°, the guiding force is the largest.
