干式双离合自变速箱液压系统设计与仿真 摘要:双离合自动变速器综合了液力自动变速器和机械变速器的优点，实现了换档动力不中断，缩短了换档时间，提升了换档品质，舒适性和操作性提高了很多，同时，提高了燃油经济性。因此，双离合器自动变速器成为了近年来热点，市场份额逐渐上升。传统的双离合器自动变速器液压系统采用的是发动机驱动的液压泵作为动力源为液压系统提供动力，而本文选择电动泵作为液压系统的动力源为系统减少了扭矩的消耗，节省了能量。本文介绍了双离合器式自动变速器的工作原理以及液压系统国内外的发展情况。本文比较了电动泵液压控制系统与传统液压控制系统的区别。对电动泵控制的双离合器自动变速器结构以及工作原理进行了分析。分析液压系统油路及各液压阀工作状态，是开发双离合自动变速箱控制系统的关键所在。在分析双离合自动变速箱控制原理基础上，利用液压仿真软件 AMESim 对其 液压控制系统中的压力控制阀进行了建模仿真，阐述了系统中控制参数对液压系统的影响，为双离合自动变速箱控制系统和控制软件的开发奠定了基础。关键词：双离合器，自动变速器，液压系统，电动泵，仿真Designing And Simulation Of Dry Dual Clutch Transmission Hydraulic System ABSTRACT: Dual clutch transmission combines the advantages of automatic transmission and mechanical transmission, has realized the shift power don't interrupt, shortens the time of shift and improve the quality of the shift, and raised a lot of comfort and operability, at the same time, improve the fuel economy. Therefore, the double clutch transmission has become a hot spot in recent years and the market share has gradually increased. The traditional dual clutch automatic transmission hydraulic system is engine driven oil pump as power source for hydraulic system, and this article choose electric pump as the power source of the hydraulic system for the system to reduce the consumption of the torque, save the energy. Analyzing the hydraulic circuit and the solenoid status is the key point in developing the control system of dual...
