摘　　要：小四轮拖拉机挂车油刹装置改进采用了分泵外置,充分利用原挂车制动器元件。试验结果表明,制动性能可靠,机组平均制动距离4.09m,最大制动踏板力不超过500N,单套成本仅150元左右。By setting the brake hydraulic cylinder outside the brake floor, the hydraulic brake systemfor small four-wheel tractor trailer has been improved, which can make full use of the components of theoriginal brake system. The experimental result shows that the performance of the new brake system is reli-able and the average brake distance is reduced to 4.09m, with the ultimate foot oprating force no more than500N. The system's cost is only around 150 yuan.
