摘要

在分析锥环式CVT结构原理基础上,开发了锥环式CVT定速比试验研究试验台。针对锥环式CVT传动副独特结构及润滑条件,设计了CVT速比控制机构和循环牵引油温度自动控制系统,并实现了与台架的一体化控制。在此基础上,建立了锥环式CVT定速比耐久性试验和效率试验方法,进行了锥环式CVT传动副定速比试验及传动效率试验。结果表明,锥环式CVT定速比试验较准确的考核了锥环传动副传动效率,其结构强度通过了验证,各速比下传动效率均在84%以上,为下阶段锥环式CVT进一步优化、改进提供了依据。

Abstract

The test bench for constant speed ratio experiment study of cone ring type CVT is developed based on the analysis of the structure principle of cone ring type CVT. Considering the unique structure of cone ring type CVT transmission pair and lubrication conditions,the CVT speed ratio control mechanism and cyclic traction oil temperature automatic control system are designed,and the integrated control of the test bench is realized. Based on the test bench,the durability and efficiency test methods for cone ring constant speed ratio experimental are put forward,and then the constant speed ratio and transmission efficiency experiment of cone ring type CVT transmission pair is carried out. The results show that the cone ring type CVT transmission pair and transmission efficiency perform well,the structure strength passes the verification,the transmission efficiency of each ratio is above 84% and a basis for the further optimization and improvement of cone ring type CVT is provided.
