Abstract
A chain-belt transmission with a continuously variable transmission ratio has input and output shafts, each carrying a pair of conical disks, with a chain belt running in a loop around the disk pairs and transmitting torque from the input to the output shaft. The friction surfaces of the conical disks and the end surfaces of the force-transfer elements of the chain belt have contour shapes that provide greater resistance to wear and thereby increase the operating life of the transmission.
