【摘要】 介绍了双离合器式自动变速器的基本结构与原理。从运动学角度出发,分析了其转速传递以及离合器控制油压与传动关系,重点分析了双离合器滑动磨合功状态时,其动力传递的功率流向;从功率平衡出发,推导了传动效率、摩擦损失功率的计算式,最后分析了其影响因素。更多还原

【Abstract】 The structure and the working principle of dual-clutch transmission(DCT)were introduced.From the kinematics point of view,DCT’s speed transmission and hydraulic clutch control relations were analyzed,focusing on the status of DCT sliding friction,the power flows was pointed out;from power balance,the transmission efficiency was derived,the friction loss power was calculated;finally,its influencing factors was also analyzed.更多还原
