根据资料统计,在74种载重量为30吨以上的矿用卡车中,采用钢板弹簧作为悬架元件的只占19%,百吨级以上的电动轮卡车中则几乎没有,采用最多的是油气悬架.油气悬架重量轻,体积小,寿命长,互换性好,性能良好.如美国伟步公司Haulpak系列电动轮汽车,凯特皮勒公司cat系列重型汽车,苏联??系列矿用卡车,国产上海SH380型32吨自卸汽车和湘潭SF3100百吨电动轮汽车等都采用了这种新型悬架元件.
According to statistics, of the 74 mining trucks with a carrying capacity of 30 tons and above, only 19% of them are leaf springs used as suspension components, and almost none of the electric-driven trucks with a capacity of more than one hundred tons are the most used oil and gas Suspension. Oil and gas suspension light weight, small size, long life, good interchangeability, good performance, such as the United States Wei step Haulpak series electric wheel car, cat Ketler Piller series heavy vehicles, the Soviet Union series of mining trucks , Made in Shanghai SH380 32-ton dump truck and Xiangtan SF3100 one hundred tons electric wheel car and so have adopted this new type of suspension components.
