However, the bend such as subway is more, the less subway orbital environment of circuit radius of turn is to the structure of bogie, strong
The technical parameters such as degree, weight and smallest curve radius propose new high standards, for example, certain new subway project is set
Meter require propose, the subway bogie frame under 30g equipment shock loadings, its static strength be no more than yield strength 50%,
The minimum curve of bogie is 36 meters by radius.And old axle box external H font welded frames as shown in Figure 1 to Figure 3,
It is only capable of meeting the 100% relatively low requirement for being no more than material yield strength under 20g shock loadings, the biography of its axle box external
The layout that system frame construction causes to take turns the framework subsidiary bodies such as wider to spacing, external axle box, motor and gear-box can not enter one
Step compression is compact, and the overall structure space-consuming in turn resulting in bogie is big, the radius of gyration is big, quality is heavy, barycenter is high, and causes
Such bogie minimum curve is at least 100 meters by radius, moreover, in order to ensure the structural strength of welded frame, its steel plate
Wall thickness is at least 20 millimeters, and the average of bogie frame overall weight is about 1.6 tons, and the axial span of two curb girder 3 is at least
1800 millimeters, these existing index parameters make it that traditional framework of the axle box external is heavy, roomy, smallest curve radius
