| 摘要： | Automated manual transmissions are now accepted as standard fitment in the heavy segment of the British commercial vehicle market. It's taken some time to get there, with pioneers such as the Mercedes-Benz EPS (Electronic Power Shift) having a mixed reception at best back in the 1980s and '90s, but any buyer who now wants a tractor unit with a conventional gearstick has to at very least put a tick in an options box when ordering their truck. The original motive behind the introduction of the automated manual transmission (AMT) was concern over the ability of conventional synchromesh gearboxes to handle the increased torque generated by the then-new Euro I diesel engines, while retaining an acceptable shift effort for the driver. Plus there was a desire to offset the extra weight of the engine intercoolers and other equipment needed to control exhaust emissions by replacing a heavy mechanical linkage with electronics. |
