ECOTRONIC - The Continuously Variable ZF Transmission (CVT) 970685
The paper describes the activities of the ZF company in the field of continuously variable transmissions, especially for passenger cars in the past, the present and the near future. As an independent supplier of transmissions for the car manufacturers ZF has to be prepared for the questions and demands of the car industry in the near future. The near future is the time for CVT's and the ZF engineers developed a strategy and a program of continuously variable transmissions for every driveline system. This program and strategy is also described in this paper.
