| Abstract: | Due to the potential benefits of a metal pushing belt, planetary gear continuously variable transmission system (CVT), there has been considerable developmental activity in this area in recent years. Development of the transmission/engine control strategies is based on detailed dynamic models and computer simulation of the transmission system. In the paper, the mechanism of this transmission system was described in detail. Approach to the vibration problem of a metal pushing belt, planetary gear continuously variable transmission system in the synchronous point, the authors think that the change rate of variable speed ratio of the CVT is one of the most important factors. The magnitude of vibration is in reverse proportion to the value of the parameter of the planetary gear, and in direct proportion to the change rate. |
