摘要

为研究混合动力汽车搭载的无同步器式AMT变速器换挡过程中啮合套与接合齿圈的啮合性能，提高换挡平顺性和缩短换挡时间，通过理论分析与虚拟样机仿真分析的方法，研究了无同步器式AMT变速器啮合套与接合齿圈啮合的过程。将啮合过程分为4个阶段：自由滑行阶段、齿尖碰撞阶段、齿尖摩擦阶段和齿间啮合阶段，建立数学模型；应用Adams建立了啮合套与接合齿圈啮合过程动力学模型，将仿真模型与理论计算值进行对比，其误差为7.3%；研究了啮合套与接合齿圈的转速差和作用在啮合套上的换挡力对啮合过程的影响，并得到最佳的转速差范围。研究结果可为换挡自动控制提供关键性指导。

Abstract

In order to study the engagement performance of engagement sleeve and engagement gear ring in the shifting process of without synchronous AMT transmission mounted on hybrid vehicle, improve the smoothness of gear shifting and shorten the shifting time, the theoretical analysis and the virtual prototype simulation analysis method are used to study the engagement process between engagement sleeve and engagement gear ring of AMT transmission. The engagement process is divided into four stages: free sliding stage, tooth tip collision stage, tooth tip friction stage and inter-tooth meshing stage, a mathematical model is established. The dynamics model of the engagement process is established by Adams. The simulation model is compared with the theoretical calculation value, and the error is 7.3%. The effects of the speed difference between the meshing sleeve and the engagement gear ring and the shift force acting on the meshing sleeve on the meshing process are studied, and the optimum range of the speed difference is obtained. The research results of the study can provide critical guidance for automatic shift control.
