Volvo Trucks First with Automatic All-Wheel Drive
Volvo Trucks’ new feature Automatic Traction Control activates the drive on the front axle automatically when in motion, if the truck risks getting stuck. The driver enjoys improved maneuvrability, and the owner benefits from lower fuel consumption and less wear and tear on the truck.
Volvo Trucks is the first truck manufacturer in the world to offer automatic engagement of all wheel drive on construction trucks. The Automatic Traction Control function activates the front wheel drive when the rear wheels lose traction on slippery or soft ground.
“Many drivers connect front-wheel drive or differential lock in good time before a difficult section of terrain, in order to avoid getting stuck. Volvo Automatic Traction Control engages the front wheel drive when in motion, and only for the short time that it is really needed,” says Jonas Odermalm, Construction Segment manager at Volvo Trucks.
Developed for tough industrial environments
The solution consists of software connected to the wheel speed sensors which detect and control wheel drive. When a rear wheel starts to slip, the power moves automatically to the front wheels without the truck losing torque or speed. A dog clutch activates the front-wheel drive in just half a second. The clutch is lighter and has fewer moving parts than a traditional solution with permanent all-wheel drive. If the driver encounters particularly rough ground, then it is possible to manually lock the other differentials at both front and rear.
Better maneuvrability and less fuel
The driver also avoids extra fuel consumption and wear on the driveline and tires, that the constant engagement of front-wheel drive normally results in. Automatic Traction Control ensures that the optimal drive combination is always enabled and removes the decision from the driver.
“Automatic Traction Control is yet another example of how innovative technology can make things easier and smarter than before. Just like the Volvo I-Shift revolutionized the gearbox, we are confident that this new development will do the same for the driven front axle,” says Ricard Fritz, vice president, Volvo Trucks Brand.
