最近,日本日产柴油机工业公司在载重车的液压或气压制动系中选用了载荷控制分配阀。所谓载荷控制分配阀,就是按照轴负荷的大小,控制制动器的工作压力,使前后轮同时接近抱死的装置。本文概要地介绍了该阀的特点、效果、结构及性能。一、前言制动性能的主要指标是:制动距离或者以减速度来表示的制动效率、耐衰退性以及恢复性能等。从安全的角度来看,制动稳定性与上述各项指标同等重要。载重车和大客车等大型车辆在制动时产生的前后轮跑偏现象以及鉸接车辆的侧向折叠现
Recently, Nissan Diesel Industry Co., Ltd. of Japan selected a load-controlled distribution valve in hydraulic or pneumatic braking systems for trucks. The so-called load control distribution valve, is in accordance with the size of the shaft load, brake control the work pressure, so that the front and rear wheels at the same time approaching the lock device. This article presents an overview of the valve’s features, effects, structure, and performance. First, the foreword Brake performance of the main indicators are: braking distance or deceleration to indicate the braking efficiency, resistance to deterioration and recovery performance. From a safety point of view, braking stability and the above indicators are equally important. Front and rear wheel run-away phenomena caused by large vehicles such as trucks and bus during braking, and lateral folding of articulated vehicles
