摘　　要：以某8×4重型自卸车为分析对象,建立了四轴汽车的制动力学模型,对该车在满载、超载情况下进行各轴载荷的计算,前、中、后桥制动力矩和制动力分配分析,在此基础上,提出了多轴汽车的行车制动性能分析方法,并与该车制动性能O型试验结果数据进行对比。实例分析结果表明,该方法简单、实用,能对四轴汽车行车制动性能进行有效分析。Taking a 8 × 4 heavy-duty dump truck for the analysis of the object,the establishment of a four-axle system dynamics model car,the car at full load and overload conditions for the calculation of each axle load,front,middle and rear axle brake torque and manufacturing power distribution analysis.On this basis,an analysis method for braking performance of four-axle vehicle is proposed,and with the braking performance of the vehicle type-0 test result data are compared.The results of real sample analysis show that the method proposed is simple,pragmatic and can effectively analyze the braking performance of four-axle vehicles.
