针对某型号防爆胶轮车在矿区使用情况,该车在制动时,点刹过于灵敏,制动冲击较大,舒适性差,同时导致传动轴、液力变矩器、变速箱和驱动桥等传动元部件频繁损坏。通过对全液压制动系统重新分析,对制动阀和制动器重新匹配,利用非接触式多功能速度仪进行制动性能试验,试验结果与分析计算结果基本符合,成功解决了制动冲击的问题。 For a model explosion-proof rubber tire in the mining area, the car in braking, the brake is too sensitive, braking impact larger, poor comfort, and lead to the shaft, torque converter, transmission and drive axle, etc. Transmission components frequently damaged. Through the re-analysis of the full hydraulic brake system, the brake valve and brake to re-match the use of non-contact multi-function speedometer brake performance test, the test results and analysis of the calculation results basically meet the successful solution to the problem of brake impact .
