Volvo Trucks unveils dual clutch system for heavy vehicles

Volvo Trucks is launching a dual clutch system for heavy vehicles. The I-Shift Dual Clutch is able to maintain torque and ensure the truck does not lose any speed during gear changes.

“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,” said Claes Nilsson, President of Volvo Trucks.

According to Nilsson, I-Shift Dual Clutch consists 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.

While transmissions with dual clutches are already used in cars, Volvo Trucks is said to be the first manufacturer in the world to offer a similar solution for series-produced heavy vehicles.

“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,” said Astrid Drewsen, product manager for drivelines at Volvo Trucks.

In Europe, I-Shift Dual Clutch will be available from autumn 2014 on the Volvo FH. It will be available on the Volvo FH with Euro 6 D13 engines and with 460, 500 and 540 hp. Volvo has not commented on an international roll-out as yet.
