摘要： 为了克服下长坡工况下鼓式制动器传统喷淋降温装置各种弊端以及改善汽车使用性能， 通过利用能量守恒和制动过程内在耦合关系建立了三轴专用车制动器耦合温升模型，并进行 了验证，然后基于并列组合模糊控制策略，构建了制动器液冷模糊控制系统，对各桥车轮制 动器进行液冷水量模糊控制研究。以某型三轴专用车为例进行仿真计算。结果表明，相比传 统液冷方式，液冷模糊控制系统在保证实现各桥鼓式制动器良好控温的前提下，液冷用水量 较少，且液冷水不会流滴地面，并因结冰影响路面附着，同时汽车随车携液量明显减少，能 较好改善汽车使用性能。

Abstract: In order to overcome all kinds of disadvantages of traditional liquid-cooled temperatureregulated device (TLTD) in the downhill braking process and improving the performances of heavy-duty truck, the brake-heating coupling model is established firstly on the basis of the conservation of energy and the inherent coupling relationship of braking process, then the Liquid-cooled temperature control system (LTCS) is founded which is based on the parallelconnected fuzzy strategies and used to investigate the Liquid-cooled fuzzy control for all drum brakes. Aimed at a certain type of heavy special truck with three axles as a example, the related simulation calculations and the subsequent comparisons between TLTD and LTCS were carried out. The results show that the LTCS can use less water to regulate the temperature reduction of drum brakes well, so the surface of road is still dry because of no cooling water dripping from the outer surface of brake drum to the ground and being freezed. In addition, the amount of loading water of truck is reduced correspondingly. It is concluded that the LTCS improves the performances of truck with good effect.
