ROLLING STOCK BRAKE CONTROL METHOD Russian patent published in 2008 - IPC B60T17/22 

FIELD: transport.

SUBSTANCE: rolling stock brake control method consists in recording time intervals t₁ and t₂, measuring time interval between t₁ and t₂ and determining car with air leak source. Then, the time interval t₃ when the rolling stock head brake air line pressure reduced by A without pressure release in the rolling stock tail air pressure line by rolling stick tail brake control unit or by the operator control valve and time interval t₄ when the rolling stock tail brake air line is reduced by A are recorded. The difference between t₃ and t₄ are compared with the difference between t₁ and t₂, and the point of spontaneous air leakage is determined by the formula N_car=(1/2+Δt_mean/2t_mean)×n, where n is number of cars and locomotive sections with n≥N_car>0, Δt_mean = t₃-t₄; t_mean=(t₁+t₂)/2.

EFFECT: faster diagnostics and localisation of air leaks in rolling stock brake system air lines.
