Regularities of Changes in the Motion Resistance of Wheeled Vehicles along a Curvilinear Trajectory

The value of the motion resistance is one important characteristics that determines technical and operational properties vehicle, in particular its fuel economy under operating conditions. This article summarizes approaches to determining rolling a wheeled vehicle straight motion, which separate case from curved motion. this parameter components along path. regularities changes two-axle curvilinear trajectory are determined based on determination individual wheels, considers rectilinear additional path caused by twisting lateral displacement wheel disc relative tire patch. Analytical dependences vehicles with design features transmission, placement tires, their were obtained. It was found reducing radius curvature minimum turning increases coefficient for investigated 1.68−2.04 times relation
