货车气制动感载比例阀,经元件研制,整车样试,路试及台架模拟试验,在满足制动法规条件下,以提高制动稳定性为目标,取得满意效果。依据汽车动力设计及研制资料,建立了元件数学模型,从而提出设计动态性能最优方法;实验结果表明,动态设计的方法是正确的。 The gas-actuated proportional valve for truck gas has achieved satisfactory results with the goal of improving brake stability through component development, vehicle sample test, road test and bench simulation test under the condition of satisfying the braking regulations. Based on the vehicle power design and development data, the mathematical model of the components is established, and the optimal method for designing dynamic performance is proposed. The experimental results show that the dynamic design method is correct.
