Unlike older transmissions, the 6AP1700B is engineered for typical in urban traffic. The primary pump maintains residual pressure, and the reinforced bearings ensure longevity even when the engine shuts off at traffic lights.
With the rise of electric buses and hybrid drives, the ZF EcoLife 6AP1700B is now considered "end of life" for new production (replaced by the ZF EcoLife 2 and the eLife electric drive). However, the sheer number of vehicles produced between 2008 and 2018 means this transmission will remain on the road for another 10 to 15 years.
The helical gear geometry significantly lowers planetary gear whine, resulting in a quieter cabin experience for passengers and reduced noise pollution in residential areas.
The genius is in the gearing. The 6AP1700B features six forward gears, allowing for a wide gear spread. The lower gears are short and punchy to get the heavy bus rolling from a dead stop (the most energy-intensive part of driving), while the higher gears are tall and efficient for cruising. This ensures that the massive torque is available when needed, but doesn't drain the fuel tank when it isn't. zf ecolife 6ap1700b
To combat the high heat generated by constant braking and heavy loads, the 6AP1700B features an integrated dual cooling system with a stainless steel heat exchanger to maintain optimal temperatures. Integrated Retarder:
| Gear | Ratio | | :--- | :--- | | 1st Gear | 3.36 : 1 | | 2nd Gear | 1.91 : 1 | | 3rd Gear | 1.42 : 1 | | 4th Gear | 1.00 : 1 | | 5th Gear | 0.72 : 1 | | 6th Gear | 0.61 : 1 | | Reverse | 4.23 : 1 |
