- In this work, for the first time, analytical expressions were derived to relate all these parameters to the speed of the engine while shifting, the speed of the engine when the belt is initially engaged, the clamping force on the belt of the output pulley of the CVT, and the clamping force on the belt of the input pulley of the CVT. The predicted performance is then compared to experimental testing of the CVT during quasi steady-state shifting and shifting while accelerating from a stand still. (December 2021)
