Efficiency, package and weight are becoming more and more important in automotive industry. At the same time, drivers do not want to do without driving comfort and driving fun. Continuously variable transmissions (CVT) represent an excellent way to meet these requirements, which is evidenced by the data from current CVT applications. The number of CVTs produced worldwide has been increasing, above all in Asia-Pacific. New production applications have confirmed this trend. Despite the already very good current designs, experts are continuously working on improving the details of CVTs. The effects of these improvements (e.g. efficiency) can be described very clearly using measurement results and simulation results. CVTs can be used effectively in applications ranging from small cars to luxury vehicles. However, this requires the relevant components to be adjusted to a specific application. In this paper, the CVT chain is used to show how this element can be scaled in the lower torque range, for instance, to meet requirements for package, mass, power density and ratio spread.
