Abstract: As heavy truck users put forward higher requirements for vehicle maintenance costs, this article discusses how to solve the abnormal tire wear caused by steering problems and reduce customer operating costs. In this paper, Ackerman's theory of the angle relationship and its influence on the steering of automobiles are introduced. Under the condition of considering the lateral deflection angle of elastic tires, a theoretical angle relationship of elastic tires that is closer to reality is proposed, and theoretical analysis is carried out. Subsequently, the spatial trapezoidal model of the integral steering trapezoidal mechanism is established, and how to calculate the rotation angle of the outer wheel by using the graphical method is introduced. Finally, by sharing the case of optimizing the steering trapezoid, the case of abnormal wear of vehicle tires is solved. It is explained that the steering trapezoidal optimization method adopted in this paper is suitable for heavy-duty trucks with integral steering trapezoidal mechanism, and provides some references for the matching of integral steering trapezoid.
