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 permanently runs under optimal operating conditions and therefore 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 loop packs. By varying the number of loops in the packs and the width of the steel elements, the pushbelt can be adjusted to the power required. CVT with pushbelt can be found in various micro, mild and full hybrid configurations, with benefits in comfort and fuel economy, one example is DH-CVT. A multi-speed solution with pushbelt CVT for electric vehicles allowing electronic components downscaling and improved efficiency and performance.
