摘要
在充分阐述回流式无级自动变速传动系统起步工作机理和各关键部件工作特性的基础上,建立了该传动系统的动力学仿真模型,制定出离合器自动接合的恒转速起步控制策略,并通过系统仿真分析对所制定的控制策略加以检验。结果表明:起步离合器从动盘存在转速快速提升的特性,在同等起步时间条件下,离合器起步滑摩功低于3kJ,仅相当于传统车辆起步时产生的滑摩功的1/3。
Considering on the characteristics of the transmission system and some key units of continuously variable transmission system with reflux power, a dynamic simulation model and a control strategy are established. The design method of the new continuously variable transmission system is verified by simulation. The simulation result on this continuously variable transmission system shows that the rotating speed of the driven plate can rise up rapidly during starting clutch engagement, and the sliding friction power is lower than 3 kJ which is nearly equal to one-third of the friction power of the traditional vehicle.
