摘　　要：目前RobertBosch公司的研究开发部已经合作开发了一种新的动力换档混合电动车辆传动系,并采用制成的这种动力系装备了两部研究用的汽车,由于新开发的两E变速箱轴呈环状布置,故在这个装置中出现了循环功率。一般因为该功率由几个部件传递而造成大于输入或输出功率故循环功率导致高的啮合损失。本文对两E变速箱的循环功率进行了详细的分析。它展示出根据4个功率的线性组合给出了能量平衡方程的解,然而仅按能量平衡不可能确定唯一的解,因此,变速箱的运动学和动力学还应作详细论述,从而导出循环功率无约束工作范围的数字表述和几何描写。这种详细的阐述为燃油高效工作的策划提供了坚定的基础。Recently ,a new power-split hybrid electric vehicle drivetrain has been developed by the Corporate Research and Development Department of the Robert Bosch company and two research cars equipped with this powertrain have been built. Owing to the loop-like arrangement of the shafts in the newly developed Dual-E Transmission,circulating power can arise in this system. In general,circulating power leads to high mesh losses because the power transmitted by some components becomes greater than the input or output power. This paper presents a detailed analysis of circulating power in the DUAL-E Transmission. It is shown that the solution of the energy balance equations is given by a linear combination of four basic power flows. The factors in this linear combination,however, cannot he uniquely determined from the energy balance alone. Therefor, the transmission kinematics and dynamics are dealt with in detail. Subsequently, a mathematical description as well as a graphical representation of the circulating-power-free operating range are derived. This elaboration provides a solid basis for the development of a fuel-efficient operating strategy.
