The invention relates to a brake system and provides a parking brake control system, a control method thereof and a loader to solve the problem that a brake oil cylinder possibly bounces back and forth when liquid is filled again after pressure oil of an energy accumulator for parking brake of an existing loader is used up. The parking control system comprises a brake electromagnetic valve, a controller, a parking brake switch and a pressure detection piece, the controller controls the brake electromagnetic valve to be powered on when the parking brake switch and the duration exceed the preset duration and the pressure is larger than or equal to a detection signal of the pressure detection piece with the preset value, and otherwise, the controller controls the brake electromagnetic valve to be powered off. When the parking brake switch is in a closed state and the energy accumulator is filled with liquid to reach a preset value, multiple times of reciprocating jumping of liquid filling of the brake oil cylinder is avoided.
本发明涉及制动系统,为解决现有装载机停车制动用蓄能器压力油消耗殆尽后再次充液时制动油缸可能出现往复跳动动作的问题,本发明构造一种停车制动控制系统及其控制方法、装载机,其中停车控制系统包括制动电磁阀、控制器、停车制动开关、压力检测件,控制器在停车制动开关、持续时长超过预定时长且压力大于等于预定值的压力检测件的检测信号时控制制动电磁阀得电,否则控制器控制制动电磁阀断电。本发明在停车制动开关处于闭合态下蓄能器充液至预定值时避免制动油缸充液多次往复跳动。
