As the transportation sector accelerates its shift towards electrification, Maxion Wheels is spearheading the development of specialised wheel technologies to address the distinct requirements of battery-electric trucks. The company's deep engineering expertise and innovative approach position it as a leader in creating solutions that meet the evolving demands of electric mobility.
Electric trucks present unique technical challenges due to their substantial battery weight, which can add 2-3 tonnes compared to conventional diesel vehicles. Proposed European regulations allowing increased gross vehicle weights for zero-emission trucks further intensify the demands on wheel systems. The instant torque characteristics of electric drivetrains, often delivering 2-3 times more torque than traditional engines, combined with the stresses of regenerative braking, create unprecedented loads. These factors can increase front axle loads by up to 500 kg per wheel, necessitating stronger yet lightweight wheel designs.
Maxion addresses these challenges through material science innovation, employing micro-alloyed high-strength steels with yield strengths exceeding 550 MPa – approximately 20 percent stronger than standard wheel steels. The company's proprietary Lightweighting Process integrates advanced engineering techniques including topology optimisation algorithms that simulate natural growth patterns, finite element analysis of over 5,000 load scenarios and precision forming methods that enhance material properties.
The company's substantial investments in high-performance computing have revolutionised its development capabilities. These powerful systems enable evaluation of more than 15,000 design iterations during development cycles, sophisticated multi-physics simulations combining mechanical, thermal and fatigue analysis and digital twin validation that has reduced physical prototyping requirements by 40 percent.
Current production solutions include certified 22.5-inch steel wheels with exceptional 4,250 kg load capacity, weight-optimised designs saving approximately 50 kg per axle compared to conventional wheels, and customized variants tailored to different battery configurations. Looking ahead, with market analysts projecting electric trucks will capture 25 percent of the commercial vehicle market by 2030, Maxion is actively developing next-generation solutions including aluminium hybrid wheels for premium applications, advanced composite materials for lightweight designs and enhanced testing protocols for extreme fast-charging thermal conditions.
Ralf Duning, Vice President of Global Engineering at Maxion Wheels, said, “At Maxion Wheels, we are committed to leading the charge in e-mobility by developing lightweight wheel solutions that meet the unique demands of battery-electric trucks. Our latest designs not only enhance payload capacity but also ensure that our customers can transition to sustainable transport without compromising on performance or durability.”
