| 摘 要： | 提出了M1类车辆空、满载制动力分配系数的计算公式.以理想制动力分配曲线与实际应用的两段不同斜率制动力分配线之间面积最小为优化目标,同时保证满载状况时的制动效率不小于75%,优化设计了某微型客车变比值的制动力分配曲线.考虑制动器推出压耗,建立了各轴制动力与管路液压的转化公式,由优化后的变比值制动力分配线确定了液压比例阀的特性曲线.对制动力分配曲线优化前、后的微型客车制动距离进行的对比计算表明,优化后的微型客车制动距离明显减小.

| Abstract: | Formulas are proposed about braking force distribution coefficients of unladen and laden M1 vehicles.The optimized goal is to obtain minimum area between the ideal braking force distribution curves and practical two brake force distribution lines with different slope,meanwhile it should be ensured that under the laden condition the brake efficiency is not less than 75%,then the variable braking force distribution curve for a mini bus is optimized.The transformation formulas between the axles braking forces ... |
