Abstract
The transmissions are designed to transfer the power from the engine or from the electric machine to the wheels and, as much as possible, without power interruption and no shocks and no vibrations during shifting process. The power flow from the engine or from the electric machine is not interrupted or the interruption is insignificant to the driver and passengers, only for automated, automatic and continuous variable transmissions. Being produced into large number of units, the transmission should be used on vehicle during entire vehicle life cycle. The powertrain efficiency depends mainly on the transmission efficiency.
The continuous variable transmission (CVT) is advisable to the conventional, hybrid and electric powertrain solutions. The continuous gear ratio range is one of the major advantages the CVT because it is able to offer high comfort to all passengers. Having continuous speed ratio, the CVT is bringing fuel economy to the vehicle.
This paper highlights the possibility of developing new modular virtual models in order to be computed the losses corresponding to the belt, during different vehicle’s operating modes.
