Abstract：In order to comparing? the differences between CVTs （Continuously Variable Transmission， Pushbelt? style）with compensator and without compensator ，By the ways of study the construction， analysis the function and work principles， make the evaluation index，? calculation and testing，? it provides a references way for CVT design when make decision for secondary pulley compensator.

Key words：continuously variable transmission， compensation cylinder， compensator， balance cylinder， dynamic pressure balance， Secondary pulley
