Volvo Trucks is launching I-Shift Dual Clutch, the first transmission on the market with a dual clutch system for heavy vehicles. Transmissions with dual clutches are already used in cars, but Volvo Trucks is the first manufacturer in the world to offer a similar solution for series-produced heavy vehicles. I-Shift Dual Clutch is particularly effective in long haul operations and conditions that require a lot of gear changing, for instance on hills or on roads with lots of twists and turns, or when driving through cities with plenty of roundabouts and traffic lights. Thanks to power-shift gear changes without any interruption in power delivery, torque is maintained and the truck does not lose any speed during gear changes. For the driver, the result is more comfortable and efficient progress on the road.
"In situations that require a lot of gear changes, for instance on hills or roads with lots of curves and bends, I-Shift Dual Clutch brings an entirely new dimension to truck driving. Here at Volvo Trucks we are immensely proud to be able to offer this innovation to our customers," says Claes Nilsson, President, Volvo Trucks.
I-Shift Dual Clutch is a transmission consisting of two input shafts and a dual clutch. This means that two gears can be selected at the same time. It is the clutch that determines which of the gears is currently active. I-Shift Dual Clutch is based on I-Shift, but the front half of the gearbox has been redesigned with entirely new components.
"When driving it feels like you have access to two gearboxes. When one gear is selected in one gearbox, the next gear is already prepared in the other. With dual clutches, gear changes take place without any interruption in power delivery. As a result, engine torque is maintained and driving comfort is significantly improved," says Astrid Drewsen, Product Manager for drivelines at Volvo Trucks.
