which is based on the DIN22261-2 standard. The maximum value of calculated force was F=149,9 kN. The load operation diagram is shown on Fig. 7.

In the next step a geometrical model of the axis and its cooperating elements was created (Zienkiewicz et al., 1991). Solid finite elements were generated on the model. In addition, a constraint and a specified force was applied. In the complete calculation model, the contact connections in the upper axle bearing and the individual securing elements were also defined. The above steps are shown in Figs. 8÷10.
