Abstract
This paper describes improvement of the slip limit and power transmission efficiency of half-toroidal CVT (continuously valuable transmission) for automobile by using the power roller oflset In the CVT design, setting traction coefficient between power roller and disks must not exceed the slip limit On the other hand, the efficiency of half-toroidal CVT increases if the setting traction coefficient can be set low value. Hence, we should define the appropriate value of setting traction coefficient However the accurate value of slip limit considering the effects of deformation of CVT components has not been demonstrated. In this study, we calculated the effect of the slip limit of half-toroidal CVT on oflset of power roller which can cancel the effect of deformation of Hie CVT components and then discuss the possibility of improving the CVT efficiency.
