买一套棋牌app需要多少 www.jbqtck.com.cn ZF EcoLife開發的EcoLife傳輸，牢記不斷增長的需求上現代城市buses.The的重點是在中央要求，有關的車輛運營效率，操作，維護，修理和更換零件的成本（LCC）。方面的技術要求，LCC顯著影響油耗，壽命和可靠性，制動液和冷卻系統，以及潤滑油的更換周期。
一個新的技術允許快速鎖定的扭矩轉換器 - 燃料密集的液壓驅動階段相應縮短，從而導致更低的油耗。由于修改后的冷卻概念，ZF EcoLife是專為現代化的引擎，符合當今已知的所有排放標準?？梢允褂瞇碌暮頭淺Ｇ康淖酆銑前突核倨髦貧?，使服務的剎車的?；ず徒檔頭癯殺鏡慕峁?。由于^的行星齒輪組，齒輪改變順利的6速變速器的齒輪間距迅速加速，而不損害乘客的舒適性。后者甚至改善的事實，傳輸噪聲被減少到^低限度由于行星齒輪組的螺旋齒。
更高的扭矩的25％，15％較高的工作溫度，制動力相當高，約5％的燃料消耗比其前任：與ZF-EcoLife，公共交通運輸主管部門要擴展他們的能力，在未來同樣可以提高性能，經濟性，和乘客舒適度。因此，ZF EcoLife再次成為“綠色城市”提出了巨大的貢獻。這不僅是指較低的燃油消耗，從而降低尾氣排放;螺旋切ZF EcoLife行星齒輪組的第一次清晰地降低了噪音，乘客在公交車和行人時，總線驅動。
ZF Friedrichshafen AG developed the EcoLife transmission keeping in mind the increasing demands on modern city buses.The focus was on the central requirements of vehicle operators pertaining to the efficiency, or the LCC (costs for operating, maintenance, repair and replacement parts). In terms of the technical requirements, LCC are significantly affected by fuel consumption, life span and reliability, brake and cooling systems, as well as oil change intervals.
Currently, this technology,ZF-Ecolife, is available in India in the Volvo 8400 low floor CNG city Bus, which is undergoing trials in Mumbai with Brihan Mumbai Electricity Supply & Transport Undertaking (BEST). Similar trials of Volvo 8400 low floor CNG city Bus equipped with ZF-Ecolife has already been sucessfully run with Delhi Transport Corporation (DTC) in Delhi and Navi Mumbai Municipal Transport (NMMT) in Navi Mumbai.
ZF-EcoLife has considerable advantages over manual transmissions when it comes to comfort for both the passenger & the driver: Frequent starting, maneuvering, or operation at crawling speed optimally suit the transmission application.
A new technology permits a quick lockup of the torque converter - the fuel-intensive hydraulic driving phases are shortened correspondingly, which leads to lower fuel consumption. Due to the modified cooling concept, ZF-EcoLife is designed for modern engines complying with all emission standards known today. The new and extremely strong integrated CityBus retarder can be used for braking processes, so service brakes are protected and service costs are reduced as a result. Thanks to the precise planetary gearset, gears change smoothly; the gear spacing of the 6-speed transmission supports swift acceleration without impairing passenger comfort. The latter is even improved by the fact that transmission noise is reduced to a minimum due to the planetary gearsets’ helical teeth.
As a standard, the ZF-EcoLife transmissions have now also been programmed with the new topography-dependent TopoDyn Life control software. The continuously variable shifting program guarantees the transmission’s optimal operation at any point of the route. This process is enabled by means of individual shift points that are calculated in line with the respective route profile and the driving resistances.
25% higher torque, 15% higher operating temperature, considerably higher braking force, and about five percent less fuel consumption than its predecessor: with ZF-EcoLife, public transportation authorities that want to extend their capacities in the future can likewise increase performance, economy, and passenger comfort. Thus, ZF-EcoLife once again a makes considerable contribution to "Green Cities". This refers not only to lower fuel consumption and therefore lower exhaust emissions; the for the first time helical-cut ZF-EcoLife planetary gearset clearly reduces noise for passengers in the bus and for pedestrians when the bus is driving by.
