Commercial vehicle major Volvo Trucks has introduced the I-Shift Dual Clutch transmission which is set to equip the Volvo FH range of heavy vehicles starting from the end of 2014. While passenger cars have been using dual clutch transmissions for years, the Volvo I-Shift Dual Clutch is the first such gearbox to be introduced in heavy vehicles.
The I-Shift Dual Clutch transmission is based on Volvo's I-Shift AMT but the first half of the gearbox is redesigned with entirely new components. Just like in the passenger cars, the gearbox consists of two input shafts and two clutches which can pre-engage two gears at a time. The system determines which of these two gears should be engaged, based on the driving situation.

The advantage comes in the form of lightening quick gear shifts which enable an almost uninterrupted power and torque delivery to the wheels. In case of trucks which are operating in conditions that require frequent gear changes such as hilly terrain and twisty roads, the dual clutch transmission will ensure that there is no loss in momentum during gear shifts.
According to the company, the Volvo I-Shift Dual Clutch gearbox noticeably enhances the drivability of heavy trucks in tricky conditions thereby providing a safe and relaxed driving experience. Further, the seamless gear changes of a dual clutch unit causes less movement to the cargo making it easier to transport liquid cargo, animals, tankers, etc.
