Always at the optimal operating point thanks to continuous adjustment
The transmission ratio of the CVT is continuously variable as the pushbelt rotates between two pulleys consisting of two conical sheaves located on the input and output shaft. These pairs of conical sheaves adjust the running radius of the pushbelt based on speed and torque. This results in an optimal ratio of the torque required and engine speed at all times. That way, the engine is permanently run under optimal operating conditions. Fuel consumption and CO₂ emissions are reduced.
The pushbelt is made up of hundreds of individual specially designed steel elements, which are strung together along two high-alloy steel ring packs. By varying the number of rings in the packs and the width of the steel elements, the pushbelt can be adjusted to the power required.
