ZF EcoLife milestone
ZF has manufactured 100,000 units of its EcoLife six-speed automotive transmission
ZF has managed to design a system that reduces fuel consumption with its start-stop function for city driving, designed for the 6-speed automatic transmission.
"Whether it’s for a city bus or coach, EcoLife meets the demands of all bus applications," ZF transmission systems manager Andreas Moser says.
The TopDyn Life control software is a feature that helps improve fuel efficiency, according to the company. It selects the best shifting strategy for the respective topography and also adjusts the braking force, while factoring-in driving resistances.
The integrated primary retarder is incorporated into the vehicle's brake management system and supports high braking power even at low speeds. This effectively reduces demand on the vehicle's service brakes.
The EcoLife automatic transmission is available in seven versions with input torques ranging from 1000 to 2300 newton meters, for buses with a gross vehicle weight of up to 32 tonnes.
ZF has been producing the EcoLife automatic transmissions since 2007.
"The market launch began parallel to the production of the preceding model, the Ecomat transmission, which was phased out in 2015," Moser says.
"EcoLife has become well-established on the global market. This is especially thanks to the technological innovations that we have continually added."
