Wide range CVT consists of a half toroidal CVT and a differential gear. The toroidal CVT consists of two disks and a power roller, the rotational speed of the output disk can be changed by the inclination angle of the power roller. The rotation of two disks are transmitted to the differential gear, and those differences are transmitted to the axle. Therefore, this power transmission can continuously change the gear ratio from forward to reverse by changing the inclination angle of the power roller. The rotation of the input disk is transmitted to the output disk through the power roller by the friction. Therefore, the frictional force between the two disks and power roller is greatly related to the transmission efficiency. Several kinds of rubber materials are tested to improve the transmission efficiency, and polyurethane has been selected.
