The invention discloses a hydraulic brake circuit control system and a telescopic boom forklift, and the hydraulic brake circuit control system comprises a service brake circuit which comprises an axle brake, a service brake valve and a flow regulating valve, a working oil port in one side of the service brake valve is connected with an axle brake through a service brake working oil way so as to control the axle brake to charge or discharge liquid; the hydraulic pump is connected with an oil inlet in the other side of the service brake valve through a first pumping oil way, and the flow adjusting valve is arranged in the first pumping oil way to adjust the liquid filling flow or the liquid discharging flow of the axle brake. A traditional prefill valve and a prefill loop are omitted, the brake oil is directly supplied to the service brake loop through the hydraulic pump, the brake oil is supplied sufficiently, response is fast, and the whole brake system is further simplified. For axle brakes of different specifications and sizes, the flow can be adjusted through the flow adjusting valve, so that the service braking response time is adjusted, and the universality is better.

    本申请公开了一种液压制动回路控制系统和伸缩臂叉车,液压制动回路控制系统包括行车制动回路,包括车桥制动器、行车制动阀和流量调节阀,行车制动阀一侧的工作油口通过行车制动工作油路与车桥制动器相连以控制车桥制动器充液或排液;以及液压泵,通过第一泵送油路与行车制动阀另一侧的进油口相连,流量调节阀设在第一泵送油路中以调节车桥制动器充液或排液的流量。本申请取消了传统的取消了充液阀及充液回路,通过液压泵直接向行车制动回路供应制动油,制动油液的供应充分,响应快,更简化了整个制动系统。针对不同规格大小的车桥制动器,通过流量调节阀可进行流量调节,从而调节行车制动响应时间,通用性更好。
