LANDMARK: Volvo innovation to hit FH models

Volvo Trucks are launching the first automated transmission for heavy vehicles with a dual-clutch system.

Available on FH models with Euro VI D13 engines with the 460, 500 or 540hp options from the autumn, I-Shift Dual Clutch aims to ensure improved driver comfort and efficiency.

Power-shift gear changes ensure torque is maintained without interruption in power delivery and, consequently, the truck loses no speed.

Claes Nilsson, President of Volvo Trucks, said: “In situations that require a lot of gear changes, for instance on hilly or windy roads, 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.”

I-Shift Dual Clutch is a transmission consisting of two input shafts and a dual clutch, meaning 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,” added Astrid Drewsen, Product Manager for Drivelines at Volvo Trucks.

“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.

“For trucks, this gearbox will truly make a major difference to driveability.

“The heavier the transport and the tougher the operating conditions, the more you will gain with I Shift Dual Clutch.

“Power-shift gear changes, where there is no interruption in power delivery, means it is easier to keep up with traffic, especially on difficult stretches of roads.

“The result is more relaxed and safe driving.”
