Title:
METHOD OF ELIMINATING SEIZURE OF SLAVE CYLINDER OF BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/106993
Kind Code:
A1
Abstract:
A method of eliminating seizure of a slave cylinder of a brake device. In the brake device, when pistons (38A, 38B) of a slave cylinder (23) seize at an advanced position, outlet valves (60, 61) are opened to discharge a brake liquid within wheel cylinders (16, 17: 20, 21) to a reservoir (62). Then, inlet valves (54, 56) and the outlet valves (60, 61) are closed and a pump (64) is activated. This causes the brake liquid within the reservoir (62) to be supplied to the liquid pressure chambers (39A, 39B) of the slave cylinder (23), enabling the pistons (38A, 38B) of the slave cylinder (23), which have seized at the advanced position, to be pushed back to a retracted position. When the seizure of the pistons (38A, 38B) is eliminated in this way, the brake liquid pressure generated by the master cylinder (11) can be supplied to the wheel cylinders (16, 17: 20, 21) via the liquid pressure chambers (39A, 39B) of the slave cylinder (23), and thus the method can back up the brake device when a failure occurs in the slave cylinder (23).
