Continuously variable transmissions have attracted a great deal of interest in recent years because they shift with very little shock and offer significant advantages for acceleration performance and fuel economy for automobile.In this paper,the transmission mechanism was discussed in detail.The force differential equations of 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 ratio and torque ratio were established.On the basis of the study,the tension force of metal rings and the thrust force of metal blocks were calculated.The research result in this paper can be used to analysis the strength of the metal rings and the metal blocks and improve the load capability of the CVT gearbox.
