摘　　要：研究了推力钢带式CVT和链条式CVT的功率损失即效率特性,特别针对传动链条和推力钢带,从结构及工作原理分析两者在传动效率上的差异,并且通过台架效率试验对比两种技术的效率表现。研究结果表明:链条式CVT在传动效率上的综合表现优于推力钢带式CVT,特别在LOW速比和OD速比条件下,链式CVT效率优势更明显。This thesis investigated the mechanical efficiency of the push belt CVT and chain CVT, especially in transmission chain and thrust steel belt; Firstly, the power loss of the two types＇ CVT belt was analyzed according to the theoretical working principle, and then the efficiency on the test bench was tested. As a result： the chain CVT＇ s mechanical efficiency is better than the push belt CVT＇ s, especially at the condition of Low and OD ratio.
