BRAKE SYSTEM FOR SHINKANSEN VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a brake system for a Shinkansen vehicle in which an idle running time can be shortened in order to shorten the idle running distance.;SOLUTION: The brake system for the Shinkansen vehicle includes a brake control device 200 which receives an emergency brake command EB and generates air pressure P1 of magnitude corresponding to the command EB, a pressure generating unit 310 having a pressure regulating valve 311 regulating an air pressure to the air pressure P2 of previously decided magnitude and a solenoid valve 312 performing selection whether the air pressure P2 is output in accordance with only the command EB or not, a double check valve 320 in which the air pressure P1 and P2 are input, and a higher pressure out of the input air pressures P1 and P2 is made to flow selectively, and a pressure intensifying cylinder 500 converting the air pressure selected by the double check valve 320 to oil pressure. Then, the length of piping L2 from the pressure generating unit 310 to the double check valve 320 is quite shorter than the length of piping L5 and L3 from the brake control device 200 to the double check valve 320.;COPYRIGHT: (C)2012,JPO&INPIT
