有效改善换档动力中断的车用有源传动装置

An Active Vehicle Transmission Device Reducing Torque Interruption

摘要:

针对AMT换档过程中的动力中断和并联混合动力汽车中发动机和电机双动力源耦合工作问题,提出了一种基于定轴式齿轮变速箱的混合动力车用有源传动装置,通过电机与变速箱的集成设计使得电机和发动机联合工作的输出特性更加符合车用工况需求,对现有技术继承性好,具有较好的推广应用价值.

Abstract:

Torque interruption occurs during gear shifting of automated manual transmission (AMT). An active transmission device electrified manual transmission (eMT) is proposed for hybrid electric vehicle (HEV) application. Key technical characters of eMT are fixed axle gearboxes and parallel HEVs. Through integrated design of motor and transmission, eMT can fully coordinate the multiple power sources to meet the vehicle power demand. This technology makes use of the existing fixed axle transmission technology by overcoming the torque interrupting shortcomings.
