摘要

为提高双离合自动变速器(DCT)中的液压控制系统的控制精度,以自主研发的七速对置双离合自动变速器的电液控制系统为研究对象,针对同步器和离合器的不同工作特性,通过对滑阀油口开度的控制来实现对同步器和离合器作动缸的动作控制,从而实现动力换挡。仿真结果表明,液压阀油口开度对输出油液的压强和流量有直接影响,通过对油口开度的控制可以使作动缸满足作动要求。
        In order to improve the control precision of hydraulic control system in dual clutch automatic transmission, this paper takes the electro-hydraulic control system of self-developed seven-speed double-clutch automatic transmission as the research object. According to the different working characteristics of the synchronizer and the clutch, motion control of synchronizer and clutch's cylinder is achieved through valve opening control, so that the power shift can be realized. The simulation results show that the opening of the hydraulic valve port has a direct impact on the pressure and flow of the output, and the control of port opening can make the cylinder meet the requirements of operation.
