lightweight tractor from the outset with hand quantitative design, through the optimization of the vehicle structure, the use of lightweight materials and new technology, in order to ensure the bearing capacity under the premise of realizing the whole weight. For example, CAE were analyzed by the finite element software design, according to the various parts of the force to change the thickness and complex variable section structure, in ensuring the premise of sufficient strength under the maximum reduction of local thickness is not necessary, it can greatly reduce the weight of the vehicle structure. The Aluminum Alloy shell transmission, high strength single stringer frame, before and after the little leaf spring suspensions and a large number of lightweight materials used for lightweight contribution too, plus the corresponding lightweight trailer or coat, vehicle weight reduction is very considerable. In order to reduce the minimum weight 1 tons, it means that the tractor can Dora 1 tons of goods, if a year to run 200 thousand km, according to the freight cost now, a year more than income of 3~4 million yuan, and truly reflects the heavy truck should be "efficient" trait. Dynamic configuration, lightweight high-end tractor using 6K10 engine, maximum power of 400 horsepower, maximum torque of 1800N• m, equipped with 16 speed manual transmission, 13 tons of single-stage reduction drive axle, can completely satisfy the requirements of lightweight domestic traction car market.
