摘　　要：分析了某轻型载货汽车理想制动压力分配和制动力调节装置调压特性,提出了在轻型货车上安装制动力调节装置的匹配方法,即通过感应载荷的变化自动调节前、后轴制动力分配比例,可使其接近理想制动力分配曲线。对车辆匹配制动力调节装置前、后的制动性能进行了理论计算与道路试验,结果表明,匹配制动力调节装置可使该轻型货车的制动性能明显提高,制动稳定性和安全性得到改善。Pressure regulating characteristics of braking force regulator and the ideal braking pressure distribution of a light duty vehicle were analyzed in this article, and matching method for the braking force regulator was proposed, namely, by sensing load change to regulate front and rear braking force distribution proportion automatically, enabling it approach to an ideal braking force distribution＇curve. Theoretical computation and road test were made to analyze the braking performance of the vehicle with or without the braking force regulator, the results showed that, with the matched braking force regulator, braking performance of thigh light duty vehicle was obviously improved and braking stability and safety were improved.
