The newly designed six-speed powershift transmission, ZF EcoWorld, features an integrated reversing function and is used in DMUs (Diesel Multiple Units). It enables an unrestricted towing and sailing function which can save an additional five percent in fuel depending on the route, engine type and load condition. The transmission achieves maximum efficiency and is equipped with a powerful torque converter. All transmission functions are controlled by electronics fitted directly on the transmission (transmission control unit). ZF EcoWorld can be used for new vehicles and for the field of repowering.
The integrated primary retarder, which only requires a small installation space, provides for strong braking power even at low speeds. In addition to the oil cooler that has been integrated into the transmission, a heat exchanger contributes to the high cooling performance of the EcoWorld. The improved heat management extends the oil change intervals and service life, making the transmission even more reliable and easier to service. This keeps the life cycle costs low.
