摘　　要：为提高无级变速器在重型专用汽车上的适用性,提出了一种通过非圆齿轮传动的新型机械式无级变速器传动方案,并基于该传动方案的结构组成,首先理论推导了其传动比范围公式,其次通过SolidWorks软件建立了其装配模型,最后利用Adams软件对其传动性能进行了仿真研究,验证了其实现无级变速的可行性。In order to improve the applicability of the CVT(Continuously Variable Transmission)in heavy-duty special vehicles,the paper proposes a new mechanical continuously variable transmission scheme through non-circular gear transmission.Based on the structural composition of the transmission scheme,the formula of the transmission ratio range is introduced firstly,and then its assembly model established by SolidWorks software,and the performance of the transmission was simulated finally by Adams software,which proves the transmission scheme feasibility of achieving infinitely variable speed.
