CONTROL METHOD OF ELECTRICALLY CONTROLLED BRAKING CIRCUIT OF MULTI-CIRCUIT BRAKING DEVICE HAVING BRAKE CONTROLLED BY PRESSURIZED MEDIA AND ITS APPARATUS

摘要

PURPOSE: To avoid the occurrence of uneven braking abrasion by providing a brake circuit operated by pressure applied from a braking value transmitter and a brake circuit electrically controlled, and controlling the latter brake circuit in accordance with the pressure. CONSTITUTION: This brake system is constituted of a brake circuit I operated by a pressure signal from a braking value transmitter 15 and an electrically controlled brake circuit II. The brake circuit I has brakes 1, 2 to be operated by a pressure medium applied from a pressure medium reservoir 14, and the brake circuit II has brakes 9, 10 to be operated by a pressure medium applied from a pressure medium reservoir 13 through pressure intensifiers 7, 14. Therefore, braking pressure of the brake circuit I is detected by a pressure sensor 3 and braking pressure on the downstream side of the pressure intensifiers 7, 14 of the brake circuit II is detected by pressure sensors 8, 11 respectively, and each of the pressure intensifiers 7, 14 is controlled in accordance with a control signal found from the output of the pressure sensor 3 on an electronic control device. 4.
