70年代末80年代初,农用运输车开始投入农村市场,经过十几年的持续高速发展,1997年年产量达到262万辆,社会保有量达1200多万辆。这一新生事物引起了社会的广泛关注、争论和思考。农用运输车红红火火的市场形势,也引起了农业机械、道路运输的机动车辆和整个机电产品等行业的研究和探索。农用运输车结构演变及现状 1.农用运输车结构演变过程三轮农用运输车在发展初期,几乎全部采用170或175柴油机作动力,传动系为一级带传动加一级链传动。与摩托车结构相似,驾驶员跨骑在发动机上,座垫位置较高。80年代后期,通过对车架结构的改进,使驾驶员得以采用乘座方式,传动
In the late 1970s and early 1980s, agricultural trucks started to enter the rural market. After more than a decade of sustained and rapid development, the annual output in 1997 reached 2.62 million and the social ownership reached more than 12 million. This new thing has aroused widespread concern, controversy and thinking in the community. Agricultural booming market situation of agricultural vehicles, but also caused the agricultural machinery, road transport of motor vehicles and the entire mechanical and electrical products and other industries research and exploration. Structure evolution and status quo of agricultural transport vehicles 1. Evolution of agricultural transport vehicle structure In the early stage of development, almost all of the three-wheeled agricultural transport vehicles were powered by 170 or 175 diesel engines. The drive train was a belt drive and a chain drive. Similar to the structure of a motorcycle, the driver straddles the engine and has a high seat cushion. The late 1980s, through the improvement of the frame structure, so that drivers can take the ride mode, transmission
