ZF EcoLife
The ZF EcoLife transmission is a 6 speed planetary transmission for medium capacity applications with rapid speed variation, such as city buses and diesel commuter rail, designed by ZF Friedrichshafen. It features boosted operating economy, longer service life, and higher temperature resistance for operation with Euro 5-6 compatible engines, compared to ZF Ecomat. It also boasts an integral retarder, longer operational intervals between oil changes, higher torque capacity, and "Dynamic, topography-dependent drive program selection" among others. History The ZF Ecolife has been in manufacturing since 2007, parallel to the ZF Ecomat until 2016. The difference between Ecolife and Ecomat in structure mainly lies in the design of the planetary gear set - the connection method between the three-wave gear set and other gear sets has changed, so that the clutches at the front end of the planetary gear set are reduced from three to two; The spur gear was changed to a helical gear, which si ...

Commuter Rail
Commuter rail, or suburban rail, is a passenger rail transport service that primarily operates within a metropolitan area, connecting commuters to a central city from adjacent suburbs or commuter towns. Generally commuter rail systems are considered heavy rail, using electrified or diesel trains. Distance charges or zone pricing may be used. The term can refer to systems with a wide variety of different features and service frequencies, but is often used in contrast to rapid transit or light rail. Similar non-English terms include ''Treno suburbano'' in Italian, ''Cercanías'' in Spanish, Aldiriak in Basque, Rodalia in Catalan/Valencian, Proximidades in Galician, ''Proastiakos'' in Greek, ''Train de banlieue'' in French, '' Banliyö treni '' in Turkish, ''Příměstský vlak'' or ''Esko'' in Czech, ''Elektrichka'' in Russian, ''Pociąg podmiejski '' in Polish and ''Pendeltåg'' in Swedish. Some services share similarities with both commuter rail and high-frequency rapid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ZF Ecomat
The ZF Ecomat automotive transmission was specifically designed by ZF Friedrichshafen AG primarily for city-buses and motorcoaches. It has several generations – all of the automatic transmission type, and many variants. The latest variants use a lock-up torque converter along with a retarder. Some variants are listed below. Gear ratios Ecomat I (1980–1985) Gear ratios Ecomat I/II/IV (1985–2016) 1st generation — Ecomat (1980–2002) All generations of the Ecomat series are no longer in production. *4HP500 / 5HP500 / 6HP500 — four-, five- or six-speed; maximum input torque of 1100 Nm *4HP590 / 5HP590 / 6HP590 — four-, five- or six-speed; maximum input torque of 1250 Nm *4HP600 / 5HP600 / 6HP600 — four-, five- or six-speed; maximum input torque of 1400 Nm 2nd generation — Ecomat 2 (1997–2007) All generations of the Ecomat series are no longer in production. *4HP502/C / 5HP502/C / 6HP502/C — four-, five- or six-speed; maximum input torque of *4HP592/C / ...

List Of ZF Transmissions
This list of ZF transmissions details those automotive transmissions created by the German ZF Friedrichshafen AG engineering company. There are two fundamental types of motor vehicle transmission: *Manual – the driver has to perform each gear change (i.e., the driver is required to shift gears) * Automatic – once placed in drive (or any other 'automatic' selector position), it selects the gear ratio dependent on engine speed and load automatically. Furthermore, they may also be manufactured solely as a gearbox, and use an entirely separate final drive unit (including its differential) – or be supplied as a transaxle, which includes both the gearbox and final drive unit within one housing. Cars and light vehicles These may be used in motor cars (automobiles), or light commercial vehicles such as car-derived vans. Manual transmissions 4-speed longitudinal * S4-12 – Lotus Elite type 14 (optional), Autocars/Reliant Sabra sports * S4-18 – Bedford Van, Opel Blitz Van ...
