New generation light commercial vehicles are expected to have lower steering effort, high self centering and less turning circle diameter covering large variety of wheelbases from 2.8 m to 4.5 m even with mechanical steering and keeping same number of total turns of steering wheel compared to old generation light commercial vehicles.To address above requirements, below parameters related to steering and rigid front axle were studied. The effect of above parameters was studied in isolation and combination. This optimization has resulted in least steering effort and least turning circle diameter in light commercial vehicles with mechanical steering and option of power steering could be eliminated for cost reduction.The changes which were done have reduced the steering effort by 44% and turning circle diameter by 13.5% compared to old generation light commercial vehicles.
