Abstract:
Continuously variable transmissions have attracted a great deal of interest in recent years because they shift with very little shock and offer significant advantages of acceleration performance and fuel economy for automobile.The slide angle is very important physical parameter in belt study. It's magnitude expresses the changing of direction of friction force's and makes the distribution of force very complicated. In this paper,the reason of the slide angle has been discussed. The formulae of wrapping angle relation with slide angle is put forward. The magnitude of slide angle is computed by used the Runge Kutta method in different speed ratios. On the basis of study a new descrete numerical analyse approach is proposed to analysis and calculate the tension and thrust of the key work piece's the metal rings and the metal blocks of the metal pushing type continuously variable transmission respectively under different speed ratios and torque ratios. The research result in this paper can be used to analyse the strength of the metal rings and the metal blocks and improve the load capability of the CVT gearbox. [WT5HZ]
