Choosing an axle configuration used to be as simple as determining how many wheels you wanted on the ground and whether or not you wanted power to all of them.
Today, there’s a myriad of options available that blend some of the best parts of a traditional 6X2 or 6X4 into something entirely new.
Designed for segments with a high payload diversity, Volvo’s Adaptive Loading Axle uses an electronic control module and a hydraulic actuation system to create a fully automatic drive axle capable of adjusting weight and downforce as the unit’s load changes, providing maximum traction and fuel economy without input from the driver.
“98 percent of the time, the system will take care of itself especially when it comes to lifting and lowering the axle for the payload support,” Chris Stadler, Volvo Trucks North America product marketing manager for regional haul applications, said.
When the truck is loaded, the system uses pressure input from the suspension to balance weight between the two axles.
As the load lightens, more weight is automatically shifted onto the drive axle. Once the truck is empty, the non-drive front axle automatically lifts off the road and tucks out of the way, allowing the truck to operate in a 4×2 configuration.
The driver also has the ability to raise and lower the axle, and balance the payload, as conditions dictate.
