摘　　要：自主研发了新型双离合器自动变速器的液压控制系统。采用电机齿轮泵与蓄能器配合的适时供油方式,避免了传统双离合器变速器液压源供油量过剩造成的能源浪费,能够达到快速、精确控制油压的目的。利用AMESim软件建立液压系统模型,并进行液压系统动力学分析,仿真结果表明带蓄能器的供液系统使得离合器建压响应更快。Aiming at the hydraulic control system of a newly self-developed dual-clutch automatic transmission,a type of motor gear pump coupled with the accumulator supplying the oil in a timely way was adopted in this study,which avoided the waste of energy caused by excessive oil supply of the hydraulic resource in the traditional dual-clutch transmission system.So the purpose to control the oil pressure fast and precisely could be achieved.For this reason,the hydraulic system model was established by using the AMESim software in this paper,and the hydraulic system dynamics analysis was proceeded.In a conclusion,the liquid supply system which coupled with the accumulator enables the building of the oil pressure to respond faster.
