Abstract

PURPOSE: To secure braking action at the time of car parking and stopping by locking a service brake in braking condition when predetermined handling force works on the parking condition when predetermined handling force works on the parking brake a braking system, in which the service brake for normal braking is also utilized as a parking brake in parallel at the time of car parking and stopping.
CONSTITUTION: At the time of using an oil service brake 11 jointly with a parking brake 30, a brake pedal 13 is first stepped to put the service brake 11 in braking condition. Then a main switch 38 is closed and a parking brake hand lever 31 is pulled up. When its handling force reaches more than predetermined value, a handling force sensor 47 is energized and a contact 42 of an electromagnetic relay 40 is closed. Subsequently, a solenoid valve 37 is closed and the service brake 11 is locked in braking condition. Further, at the time of pulling up operation of the lever 31, the solenoid valve 37 is certainly maintained in closed condition because a handling switch 49 is closed, and a contact 45 of an auxiliary electromagnetic relay 43 is closed due to its energized coil 44.
