AB The article highlights is determination of the main strength indicators of the modernized brake lever transmission for a wagon bogie. The special feature of this modernization is that the technological pin-hole in the strut is displaced by 112 ± 2 mm towards the bolster beam, i.e., in line with the pendulum joints. This helps to eliminate abnormal wear of the brake pads in operation. To substantiate the proposed modernization, the strength of the brake lever transmission was calculated. It was found that the maximum equivalent stresses were 124 MPa; they occurred in the tension member. The resulting stresses did not exceed the permissible values. Thus, the proposed modernization measures are appropriate.This research could improve the safety of rail freight operations and profitability of the rail transport.
