Review on Torque Interruption and Its Solution of Automated Mechanical Transmission

摘要:

阐述了机械式自动变速器固有缺陷产生的原因以及对车辆驾驶性能的影响;总结了目前国内外针对定轴式变速器动力中断问题的研究进展及方案,并在此基础上提出有源动力补偿以及无源动力补偿的概念;最后总结了机械式自动变速器未来发展趋势.

Abstract:

The torque interruption is the inherent flaw due to the topological structure of automated mechanical transmission(AMT).First,a brief introduction is made to the cause and the influence of the vehicle drivability of the torque interruption,and then the research on torque interruption based on fixedaxle transmission is reviewed and the solutions are discussed.The concepts of powered torque gap filler and unpowered torque gap filler are presented.At last,the future development trends of AMT is concluded.
