Evaluation of the Tire Wear Possibility Due to Non-Steerable Twin Tire Lift Axle on Heavy Commercial Vehicle 2019-26-0066

The commercial vehicle market in India is shifting to higher payload capacity vehicles due to lower transportation cost of per unit goods. To cater this requirement, the vehicle manufacturers are designing the heavy multi-axle commercial vehicles and with higher per axle loading capacity. One of such a vehicle design involves five-axle vehicle with non-steerable, twin tire, lift axle. Though using twin tires have increased loading capacity of lift axle compared to single tire self-steerable lift axle, it can cause tire scrub while vehicle is turning and leads to more tire wear. The tire wear possibility due to use of non-steerable lift axle is estimated through simulation using full vehicle model in ADAMS. The operating zone of the vehicle, where maximum tire wear can occur, is identified through simulation. Different alternatives to reduce tire wear in this situation are also discussed.
