Research on a novel configuration synthesis method of no-spin traction continuously variable transmission
2020
Abstract The no-spin design methodology of the traction continuously variable transmission (CVT) is the latest achievement in the field of CVT mechanism research. According to this methodology, four basic no-spin traction CVT mechanisms are acquired. In order to obtain more no-spin traction CVT mechanism topologies, a novel Configuration Factor Table (CFT) method for the configuration synthesis of basic no-spin traction CVT mechanisms is proposed, of which the main idea is from the basic law of separation and free combination of genes. Then the five main steps of configuration synthesis using this CFT method are described in detail. Based on this method, the configuration synthesis case studies of logarithmic CVT and conical CVT are carried out. The results show that 14 variant mechanisms of logarithmic CVT and 10 variant mechanisms of conical CVT are obtained. Among them, the swing-logarithmic CVT, rolling-logarithmic CVT, swing-conical CVT and rolling-conical CVT are considered to have the potential to become the new generation of high-power transmitting and high-efficiency traction CVTs.
