Example Embodiment

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] like figure 1 As shown, the loader electronically controlled parking brake control system includes a brake switch 1, a start switch 2, a brake solenoid valve 5, and a relay 6, and the power supply is connected to the brake switch 1 and the relay 6 through the start switch 2 respectively. , when the start switch 2 is turned to the ON position, the coil of the relay 6 is energized, the contacts of the relay 6 are closed, and the normally open contacts of the relay 6 are in the closed state. When the start switch 2 is turned to the OFF position, the power is output through the contacts Provide reverse power supply to the coil of relay 6 to ensure that the contacts of relay 6 remain in the on state, relay 6 continues to output high level, the output power of relay 6 is transmitted to the brake solenoid valve 5 through the start switch 2, and the brake solenoid valve 5 works

Abstract

The invention discloses an electronically controlled parking brake system, and belongs to the field of engineering machinery. The electronically controlled parking brake system overcomes the defect that vehicles cannot achieve effective braking under the working conditions of normal work, whole machine power off, power on again and the like. The electronically controlled parking brake system comprises a brake switch, a starting switch, a brake solenoid valve and an electric relay, and a power supply is correspondingly connected with the brake switch and the electric relay through the starting switch; when the starting switch is turned to the ON position, an electrical appliance normally open contract is in a turned-on state; and when the starting switch is turned to the OFF position, power is output to an electric relay coil to reversely supply power through the normally open contract, power output by the electric relay is transmitted to the brake solenoid valve through the starting switch, and accordingly the brake solenoid valve works. The electronically controlled parking brake system is mainly used for loading machines, and also can be used for other engineering machines which use planetary gearboxes.
