【 摘 要 】

The article is devoted to the problem of reliability augmentation of running gears elements of mining traction locomotives. Conducted studies consist of determination of convergence of calculation results and the experiment, as well as the estimate of reliability increase of the mining traction locomotives axle-box. The calculation error between calculation results and the experiment for the bracket of the axle-box hydrodamper is on average 3.39%, which is admissible for engineering calculations. The total value of the fatigue resistance stock coefficient considerably exceeds the maximum permissible fatigue resistance stock coefficient (2.83>2.0), which creates a safety margin of the axle-box of the mining traction locomotive.
