When the leakage of the entire brake pipe system at holding pressure for 1 min is greater than 5 kPa,in the brake holding position,the brake cylinder pressure of the vehicle with small leakage from the working air cylinder will continue to rise,while the faults of the working air cylinder,the volume chamber or the brake cylinder with excessive leakage rate are easily concealed.In view of the above problems,this paper proposes a method to determine the leakage point through the comparative relationship of the three pressure curves of the brake pipe,the auxiliary reservoir and the brake cylinder.
