VERTICAL OSCILLATIONS OF BOGIE VEHICLES

Considers the oscillations of bogie vehicles and the factors which must be known in order to calculate the frequency of these. As a result of the calculations, the preference for "good" riding qualities results in the selection of helical springs for primary and secondary springs. For locomotive springing, leaf springs are preferred. After discussion of amplitude limits, pitching and the relationships of tractive forces to static deflections, the application of rubber and air springs is discussed. The undesirable effects of 3 types of quill drives are discussed. Factors of drive position, and deflection caused by pitching are discussed last.
