Volvo Trucks will soon release the I-Shift dual-clutch transmission , which will be the first heavy-duty vehicle gearbox equipped with dual clutches on the market. Uninterrupted power transmission and holding torque can be achieved when shifting, so that the vehicle speed will not drop. For the driver, driving is more comfortable and efficient. “The I-Shift dual-clutch gearbox delivers the best performance when there is a need for frequent gear shifts, such as driving on a mountain road or on many turns. We are proud to be able to provide this innovative design to our customers.†Volvo Truck president Claes Nilsson said. The I-Shift dual clutch transmission has two input shafts and two clutches. Two gears can be selected at the same time. The clutch determines which gear is currently enabled. The I-Shift dual-clutch gearbox is based on the original "I-Shift" gearbox, but the first half of the gearbox uses a redesigned new structure. "When one gearbox is activated, the other gearbox will preselect the next gear. With two clutches, power transmission will not be interrupted while shifting, but will also maintain torque, which has greatly improved The comfort of driving,†explains Astrid Drewsen, Volvo Truck Product Manager. Dual-clutch gearboxes have been used in the automotive sector, but Volvo Trucks is the world's first manufacturer to apply dual-clutch solutions to heavy-duty vehicles. The I-Shift dual-clutch gearbox is particularly suitable for long-distance transportation and road conditions that require frequent gear changes, such as mountain roads or roads with many turns or city roads with many traffic lights. The application of the I-Shift dual-clutch gearbox will also greatly improve the transport of live animals and tanks, and will reduce the occurrence of slippage and trapping in wet and slippery roads such as woodland. Another major advantage of the I-Shift dual-clutch transmission is improved driving comfort. "In addition to being able to drive efficiently, smooth shifts make the cabin environment quieter," added Astrid Drewsen. The I-Shift dual clutch transmission will be used in Volvo FH trucks equipped with Euro 6 standard D13 engines.
