摘要/Abstract

摘要： 为解决铰接车辆主制动系统的制动力不足和制动稳定性差的问题,将液冷式电涡流缓速器与车桥融合设计,构建了一种电涡流缓速车桥,以避免重载挂车的制动出现“冲撞”和“折叠”现象。对电涡流缓速车桥进行了台架试验,对比分析了空载和满载时安装于牵引车和挂车上的缓速器的制动稳定性。结果表明:车辆在空载,尤其是满载时,安装在挂车上的电涡流缓速车桥比安装在牵引车上的缓速器更能使车辆有良好的制动稳定性和安全性。

Abstract: In order to solve the problem of insufficient braking force and poor braking stability of main brake system in an articulated vehicle, the liquid-cooled eddy current retarder and vehicle axle are integratively designed to construct an eddy current retarder axle for avoiding “impact” and “jackknifing” phenomena during the braking of heavy-loaded trailer. Bench test on eddy current retarder axle is conducted to comparatively analyze vehicle braking stability with retarder installed on tractor and trailer under the conditions of no load and full load. The results show that in no load, especially full load condition, with retarder installed on trailer, the vehicle will have better braking stability and safety than that with retarder installed on tractor.
