The present invention relates to an ABS system installed on a lift axle of a truck. More specifically, the ABS system for the lift axle of the truck is configured such that an ABS and a lift axle ECU are operated in association with the power operated when the lift axle is lowered, thereby simplifying a cable of an ABS power, and a diagnostic cable and an error sensing lamp are installed so a driver can detect an error in the ABS, thereby being able to be stably operated. According to the present invention of the ABS system installed on the lift axle, the ABS and the lift axle ECU are operated in association with the power operated when the lift axle is lowered, thereby simplifying the cable of the ABS power, the diagnostic cable and the error sensing lamp are installed so the driver can detect the error in the ABS, thereby being able to be stably operated, and a load sensor is installed to differentially supply a breaking force according to the load, thereby preventing the excessive wear of tires and pads, and subsequently providing an economical advantage. Moreover, when the lift axle is lowered, the ABS power is supplied, and a normal operation is performed. The braking force is differentially controlled by the load sensor so the pneumatic pressure can be properly used, thereby preventing unnecessary consumption of air, and thus the lifetime of an air compressor is extended, and fuel efficiency can be enhanced.

    본 발명은 화물차의 가변축에 장착되는 브레이크 시스템에 관한 것으로서, 좀 더 구체적으로는 가변축 하강시의 전원과 연동시켜 ABS와 가변축 ECU를 작동시킴으로써 ABS 전원의 케이블을 간소화하고, 진단 케이블과 이상 감지 램프 장착으로 운전자가 ABS 이상 유무 감지함으로서 안정되게 작동되는 화물차의 가변축용 브레이크 시스템에 관한 것이다. 본 발명에 따른 가변축에 장착되는 ABS 시스템은 가변축 하강시의 전원과 연동시켜 ABS와 가변축 ECU를 가동시킴으로써 ABS 전원의 케이블을 간소화하고, 진단 케이블과 원인 램프 장착으로 운전자가 ABS 이상 유무 감지함으로서 안정되게 작동되며, 하중감지센서 장착하여 하중에 따라 제동력을 차등으로 공급하므로 타이어 과다마모, 패드의 과다마모 방지로 경제적이다. 또한, 가변축 하강시 ABS 전원이 공급되어 정상 작동되고, 하중 감지 센서로부터 제동력을 차등 조절하여 공압을 적절히 사용함으로써 불필요한 에어 소모 방지가 가능하고, 따라서, 에어콤프레셔의 수명연장과 함께 연비를 향상시킬 수 있다.
