Just a few months after the launch of the new FH series, Volvo Trucks is presenting another world-class technical innovation – Volvo Dynamic Steering. This combines conventional hydraulic power-steering with an electronically regulated electric motor fitted to the steering gear. The result is precise steering that gives the truck driver a safer, more comfortable and more enjoyable working environment.
Claes Nilsson, President Volvo Trucks, comments: “This innovative and patented technology benefits the truck driver in all operating conditions. On the highway the dynamic steering system offers unbeatable directional stability. At low speeds, even a heavily loaded truck is so easy to steer that you can do so with one finger.”
The electric motor, which works together with the truck’s hydraulic power steering, has a maximum of 25 Nm of torque and is regulated thousands of times per second by the electronic control unit.
Gustav Neander, project manager for Volvo Dynamic Steering, explains: “The task of the electric motor is to deliver perfect steering for every single moment of operation. For instance, the system’s sensors note that the driver wants to drive straight ahead and automatically ensures that no interference from the road surface is allowed to filter up through the steering wheel.”
He adds: “Truck drivers who have tested the system during the development process have all been highly impressed.”
Volvo Dynamic Steering addresses the most frequent occupational injuries suffered by heavy goods vehicle drivers. Official figures from the Swedish Work Environment Authority reveal that truck drivers are over-represented in occupational injury statistics.
“Almost four out of ten truck drivers complain of back, neck, arm and shoulder pain every week,” says Neander. “Our improved steering system offers a more relaxed driving experience that should counteract this kind of problem in the working environment.”
He concludes: “Volvo Dynamic Steering elevates the steering of heavy vehicles to an entirely new dimension. The technology makes the driver’s working conditions more relaxed and controlled.”
