一种液压调控装置及应用其的调控单元、线控制动系统和 方法

The invention discloses a hydraulic regulation device and a regulation unit and a line control system using the same, wherein the hydraulic regulation device comprises a hydraulic control reversing valve and a high-pressure energy accumulator, the hydraulic control reversing valve comprises a valve body, a limiting seat and two valve cores, the valve body is provided with a plurality of communicated cavities, the limiting seat and the two valve cores are sequentially arranged in a first cavity of the valve body along an axis, the two valve cores slide back and forth along the axis and are internally provided with oil paths which extend along the axis direction but are not completely communicated, the two valve cores are respectively a first valve core and a second valve core, the first valve core is used as a switch communicated between an internal oil path and a corresponding oil cavity of the first valve core, an external oil path which extends along the axial direction is formed between the second valve core and the valve body, the second valve core and the limiting seat are jointly used as an internal oil path and a switch communicated between the external oil path of the second valve core and the corresponding oil cavity, and the internal oil path of the high-pressure energy accumulator is communicated with the first cavity through a second liquid inlet cavity of the valve body. The invention solves the problems that the braking efficiency of the heavy-duty vehicle is insufficient and the forced requirement of emergency braking deceleration can not be met under the power-off working condition of the motor in the prior art.
