The Layout Concept and Small Pitch Chain for Chain Type CVT

Abstract

The extension of automated transmission in passenger cars, CVT has a significant share in the market and also for the future this trend is expected. Reasons are the excellent comfort, very good efficiency, particularly in part torque range. In additional CVT has good possibilities for hybridization. Based on a consequent optimization of the components with a CVT chain, very high ratio coverage and very good efficiency is possible. A further reduction of the pitch length for CVT chain improves NVH behavior of CVT even more. This sophisticated transmission layouts and structures of chain-CVT make additional benefit and customer fulfillment.
