Evaluation of the influence of toe and camber of the steered wheels on fuel economy and tyre wear multipurpose vehicles

Abstract

Based on the analysis of elastic deformations of the wheel that occurs in the process of movement with an inclination along a curvilinear trajectory, an analytical relationship of the angles of the collapse of the convergence of the steered wheels of the vehicle, allowing at the design stage to select the most efficient ratio that provides minimum rolling resistance wheels, and, therefore, minimal tire wear and fuel consumption. Minimum rolling resistance is in direct proportion with fuel efficiency and tyre wear, This analytic dependence, allowed us to determine the relationship of the angles of the steered wheels on the basis of the condition of the minimum of rolling resistance of the wheels, live with the camber and the toe.Comparative analysis of the angles of camber and of toe-driven wheels, mass-produced cars and angles, calculated from the dependence allows to draw conclusions about the need for good tires, a wheel alignment which is close to the calculated one.
