3.In this article,the author introduces the structure characteristic of oil cylinder float drawbar assembling lift mechanism of dump truck,and on the basis of kinematics and dynamics analysis presents the method of faciliting design of its structure parameters.
5.The thermal oxidation stability and the durability of T311 are improved obviously as compared with T304. T311 has passed FZG gear test, L-60-1 thermal oxidation stability bench test and Mack transmission oil cycle bench test with applying to manual transmission gear oils for truck and bus.
T3 1 1与T3 0 4相比热氧化稳定性及耐久性有明显提高。 T3 1 1应用于卡车及公共汽车手动变速箱齿轮油中通过了FZG齿轮机试验、L 60 1热氧化稳定性台架试验及Mack变速箱循环台架试验。收藏指正
