由国机重工自主研发“智造”的全球最大马力电传动D320E型推土机bauma China 2014期间上海首发。D320E型电传动推土机在整机匹配、动力装置、驱动及控制系统、电气系统安全性、液压及冷却系统等多项关键技术领域取得重大突破,目前已申报8项专利技术。该机采用电传动,传动效率提高,与液力传动对比,可以发挥出更大的牵引力和瞬间爆发力,作业效率提高;起步转矩更大,可满足更为苛刻的坡度起步要求;全打滑点基本位于恒功率段,电机及控制器仍处于高效区,这与液力机械打滑点变矩器75%的效率相比具有明显优势,具有较好的节能效果;无变矩器、变速器及中央传动,传动部件
The world’s largest horsepower electric drive D320E bulldozer bauma China 2014, which is independently developed by SINOMACH, was first launched in Shanghai during the " The D320E electric drive bulldozer has made major breakthroughs in many key technologies such as complete machine matching, power plant, drive and control system, electrical system safety, hydraulic system and cooling system. At present, 8 patented technologies have been declared. The machine uses electric drive, transmission efficiency, compared with the hydraulic transmission, you can play a greater traction and instantaneous explosive force, improve operating efficiency; starting torque greater, to meet the more demanding requirements of the gradient start; full slippage Basically in the constant power section, the motor and the controller are still in the high-efficiency area, which has obvious advantages compared with the 75% efficiency of the hydraulic mechanical slipping-point torque converter, and has better energy-saving effect; no torque converter, transmission and central Transmission, transmission components
