Abstract

PURPOSE:To improve the durability without the service brake system being in the locked state, by passing an electric current through a double check valve between a brake valve and a joggle joint and an electromagnet arranged in a passage of a pressure gap to release them by energizing coactively with the action of the parking brake system. CONSTITUTION:On the one hand, if the parking brake system is actuated to close a sensing switch 10 followed by pushing down a lock commanding switch 11 to close once, the pressurized air in a pressurized air tank 1 is transmitted to the toggle joint 4 by the opening operation of the electromagnetic valve 7 to lock wheel brakes 5, while on the other hand, if the action of the parking brake system is released, since the sensing switch 10 is opened, a main circuit Cm and a self sustaining circuit Ch become in the open state to deenergize a solenoid 7a, the electromagnetic valve 7 is closed, the input air of the toggle joint 4 is discharged outside through the electromagnetic value 7, and the toggle joint 4 is restored to the unoperative state to release the locked state of the wheel brakes 5.
