摘　　要：齿轮-轴系统是重型汽车变速器中的主要组成部分。随着挡位的改变,其传动比和动力传递路线都会发生变化。在变速器中,1～5挡是3个轴的定轴传动,倒1挡和倒2挡是4个轴的定轴传动。本文对变速器1挡和倒1挡的齿轮-轴进行了动力学建模,并给出了相应的Matlab/Simulink模型,为重型汽车齿轮变速器的研究提出了建模与仿真的方法。The gear-axial system is the main component of heavy vehicle transmission.The transmission gear ratio and power transmit route are changed along with its shifting position.In the transmission,15 shifting are three fixed axles drive,and reverse 12 shifting are four fixed axles drive.The dynamics modeling and Matlab/Simulink moulds are built for 1 shifting and reverse 1 shifting of transmission.A method of modeling and simulation for the research of heavy vehicle transmission is offered.
